=Intro=
This is API for [[CudaText]] in Python.

* Module: cudatext. Constants, functions, class Editor, objects of class Editor.
* Module: cudatext_cmd. Constants for Editor.cmd().
* Module: cudatext_keys. Constants for on_key.
* Module: cudax_lib. High-level functions for plugins, e.g. read/write configs.
* Module: cudax_nodejs. Helper functions for plugins which use Node.js.

=Event plugins=

To make plugin react to some program event, add method to class Command. For example, method "Command.on_save" will be called by program event "on_save" - if plugin is subscribed to that event. Event methods have param "ed_self": this is Editor object in which event occured. This object is the same as object "ed" in most cases ("ed" always refers to focused editor), but in some cases event occurs in inactive editor, e.g. command "Save all tabs" calls event "on_save" for passive tabs.

Plugin can subscribe to events in several ways:

* Static subscribing in "install.inf". This is used, when plugin needs to always react to some events, with any combination of its options.

* Static subscribing via config file "settings/plugins.ini". This is used when plugin doesn't need some events initially, but after changing some options, it needs more events. File "plugins.ini" section [events] can contain lines like "cuda_modulename=event1,event2,...". File "plugins.ini" is read on plugins initialization, so after writing there, CudaText should be restarted.

* Run-time subscribing/unsubscribing via API. See description of action PROC_SET_EVENTS in app_proc().

Event handlers (Command.on_nnnnn methods) return-value is ignored is many cases, but sometimes return value True or False has special meaning. Usually the False return value blocks propagation of event to other plugins, so don't return False if not necessary.

==Events - General==

* on_open(self, ed_self): Called after file is opened from disk.
* on_open_pre(self, ed_self, filename): Called before file opening. Method can return False to disable opening, other value is ignored.
* on_open_none(self, ed_self): Called after file is opened, and none lexer was detected/set for it.

==Events - Smart commands==

* on_complete(self, ed_self): Called by "auto-completion menu" command (default hotkey: Ctrl+Space). Method should read editor text, find all needed data, and call Editor.complete() API to show the actual auto-completion listbox to user. True return value means that plugin handled the event, don't call other plugins.
* on_func_hint(self, ed_self): Called by "show function-hint" command (default hotkey: Ctrl+Shift+Space).

* on_output_nav(self, ed_self, text, tag): Called on clicking line, or pressing Enter, in the Output or Validate panel. Param "text" is clicked line, param "tag" is int value associated with line. Event is called only if app cannot parse output line by itself using given regex, or regex is not set. Param "ed_self" is None here.

==Events - Macros==

* on_macro(self, ed_self, text): Called when command "macros: stop recording" runs. In text the "\n"-separated list of macro items is passed. These items were run after command "macros: start recording" and before command "macros: stop recording".
** if item is "number" then it's simple command.
** if item is "number,string" then it's command with str parameter (usually it's command cCommand_TextInsert).
** if item is "py:string_module,string_method,string_param" then it's call of Python plugin (usually string_param is empty).

Note: To run each on_macro item (with number) later, call ed.cmd(): number is command code, string after comma is command text.

==Events priority==

By default all events in all plugins have priority=0. So for any event, if 2+ plugins handle this event, they're called in the order on module names (e.g. cuda_aa, then cuda_dd, then cuda_mmm).

You may want to handle some event first.
To change priority for your plugin event, write in install.inf event like this: "on_key+", "on_key++"... with any number of "+" up to 4. Each "+" makes higher priority. So first called "on_key" with maximal number of "+", last called "on_key" without "+".

==Lazy events==

By default all event handlers, except on_exit, are not "lazy". On_exit is always "lazy" - it means that it's called only for already loaded plugins. To make other event handlers lazy, write in install.inf event name with "~":

 events=on_focus~,on_open~,on_state~

It's allowed to combine "+" and "~" suffixes, like on_focus~++

=Callback parameter=

Callback parameter is supported in several API functions: dlg_proc, timer_proc, menu_proc, button_proc etc. For all functions, "string form" of callback is supported. For most but not all functions, "callable form" is supported too.

Parameter can be in these forms:

* callable, ie name of a Python function, or just "lambda". Internally, callable will be converted to a weird string. Note that some functions do not support "callable form". You can detect this support by reading the code of "py/cudatext.py" module, which performs the convertions from callable to string.
* string "module=mmm;cmd=nnn;" - to call method nnn (in class Command) in plugin mmm, where mmm is usually sub-dir in the "cudatext/py", but can be any module name
* string "module=mmm;cmd=nnn;info=iii;" - the same, and callback will get param "info" with your value
* string "mmm.nnn" - the same, to call method, short form
* string "module=mmm;func=nnn;" - to call function nnn in root of module mmm
* string "module=mmm;func=nnn;info=iii;" - the same, and callback will get param "info" with your value

For example:

* If you need to call function "f" from plugin cuda_my, from file "py/cuda_my/__init__.py", callback must be "module=cuda_my;func=f;"
* If you need to call it from file "py/cuda_my/lib/mod.py", callback must be "module=cuda_my.lib.mod;func=f;".

Value after "info=" can be of any type, e.g. "info=20;" will pass int 20 to callback, "info='my';" will pass string 'my'.

====app_proc - Search properties====

Actions work with props of Find/Replace dialog, and props of low-level search engine. When user runs some search command in the dialog, dialog applies its props to the search engine. So most of the time, props of dialog and search engine are sync'ed. But they aren't sync'ed if user just typed new text in the dialog.

* PROC_SAVE_SESSION: Saves session to file with given name. Returns bool: session was saved.
* PROC_LOAD_SESSION: Loads session from file with given name (closes all tabs first). Returns bool: tabs closed w/o pressing Cancel, session was loaded.
* PROC_SET_SESSION: Tells to app filename of session. Session with this filename will be saved on exit, loaded on start, shown in app title in {} brackets. Don't set here empty string. Default filename is "history session.json" without path. Missing path means that folder "settings" will be used.

====app_proc - Sidebar panels====

General notes:

* Word "tab" here means: sidebar button with attached embedded dialog, which looks like a tab.
* Caption of "tab" must not contain ",". Name of icon file - too. Tooltip string - too.
* Actions find "tabs" by caption, caption is some latin text, which is not affected by CudaText translation. E.g. caption "Code tree" always refers to Code-Tree tab, with any active translation.
* Name of icon file: path of PNG/BMP file. Icon size/dimensions should be equal to the size of current sidebar imagelist. Default is 20x20. You can detect size of this imagelist, by using PROC_SIDEBAR_GET_IMAGELIST and passing returned handle to imagelist_proc(). If filename is without path, CudaText subfolder "data/sideicons" is used.

Actions:

* PROC_SIDEPANEL_ADD_DIALOG: Adds tab, with embedded dialog. Returns bool: all parameters are correct, tab was added. Param "text" must be 3-tuple:
** Item[0]: Caption of tab.
** Item[1]: Int handle of dialog, from dlg_proc().
** Item[2]: Name of icon file.

* PROC_SIDEPANEL_REMOVE: Removes tab. Param "text" is caption of tab. (Note: actually it hides tab, dialog for this tab is still in memory). Returns bool: tab was found/removed.
* PROC_SIDEPANEL_ACTIVATE: Activates tab. Returns bool: tab was found/activated. Param "text" can be string or tuple:
** str: caption.
** 2-tuple (caption, bool_set_focus). Default for bool_set_focus is False.

* (deprecated) PROC_SIDEPANEL_ENUM: Enumerates tabs. Returns str, "\n"-separated captions of tabs.

* PROC_SIDEPANEL_ENUM_ALL: Enumerates tabs. Returns list of dict, each dict item has keys:
** "cap": str: Panel caption (not affected by translation)
** "hint": str: Button's floating tooltip (affected by translation).
** "dlg": int: Handle of panel's dialog. Can be 0, if dialog is not yet created. For example, plugins "Tabs" and "Snippet Panel" do not create the dialog until plugin is called.

** "ex3": int: mininal size of linked control (controlled by splitter)

====dlg_custom - Return value====

Dialog is closed by clicking any button or by changing of any control which has "act=1".

* If cancelled, returns None
* If get_dict=True, returns dict: {0: str_value_0, 1: str_value_1, ..., 'clicked': N, 'focused': N}
* If get_dict=False, returns 2-tuple: (clicked_index, state_text)
** "clicked_index": index of control which closed dialog (0-based).
** "state_text": "\n"-separated values of controls. Same count of items as in text, plus optional additional lines in the form "key=value". Line "focused=N" with index of last focused control (0-based) or -1.

====dlg_custom - Notes====

* Property "type" must be first.
* Property "act" must be set after "val".

* Controls sizes differ on Win/Linux/OSX, picture shows controls (Linux/Win) auto-aligned, not in CudaText, only example app:

[[File:controls_autosizes.png]]

* So it's good to use common height for single-line controls, 30 pixels is ok for edit/button/check/radio, 36 for combobox.
* Control "tabs" height cannot auto-size, please make correct height for control (it is usually like big buttons).

===dlg_proc===

 dlg_proc(id_dialog, id_action, prop="", index=-1, index2=-1, name="")

Advanced work with dialogs (forms). More advanced than "dlg_custom", forms can show in modal/nonmodal way, controls can change their value during form showing.

Often the function works with some control. To pass some control here, use one of 2 methods:

* Set param "name" to control's name. You give name to a control when you create this control. Param "name" is used if it's not empty.
* Set param "index" to control's index. You get index of newly created control from dlg_proc call. You can find the index from name, using DLG_CTL_FIND action. Param "index" is used if it's >=0 and param "name" is empty.

====dlg_proc - Types of controls====

Possible types of UI controls are described in "dlg_custom" topic.
Additional types, supported only by "dlg_proc":

* "button_ex": button, application-themed, works via button_proc()
* "editor": full-featured multi-line editor, accessible via Editor API
* "editor_edit": one-line variant of "editor"
* "editor_combo": one-line variant of "editor", with drop-down arrow
* "listbox_ex": listbox, application-themed, works via listbox_proc()
* "paintbox": control which must be painted by plugin via canvas_proc()
* "statusbar": statusbar: panel with one horizontal row of cells, works via statusbar_proc()
* "toolbar": toolbar: panel which holds buttons with icons, works via toolbar_proc()
* "treeview": tree structure with nodes and nested nodes, works via tree_proc()

====dlg_proc - Forms properties====

* "cap": str: Caption of form.
* "x", "y": int: Position (screen coordinates), left/top.

* "autosize": bool: Form resizes to minimal size, which shows all visible controls. Don't use it together with "resize".
* "keypreview": bool: If on, then key press calls on_key_down before passing key to focused control. Should be True if form needs to handle on_key_down.
* "p": int: Parent handle. Set this property to int handle of any windowed UI control or form, this control/form will be parent of form.
* "focused" (only for reading): index of currently focused control.
* (deprecated) "resize": bool: Border of form has "resizable" style.

====dlg_proc - Forms events====

These are also properties of forms.

* "on_resize": Called after form is resized.
* "on_close": Called after form is closed.
* "on_close_query": Called to ask plugin, is it allowed to close form (in any way: pressing Esc key, clicking X icon, pressing Alt+F4 or similar hotkey). Plugin must return bool, if True then form will be closed.

How to get nice key description in on_key_down, e.g. "Ctrl+Alt+Esc" from id_ctl=27 and data="ca":

<syntaxhighlight lang="python">
    str_key =\
      ('Meta+' if 'm' in data else '')+\
      ('Ctrl+' if 'c' in data else '')+\
      ('Alt+' if 'a' in data else '')+\
      ('Shift+' if 's' in data else '')+\
      app_proc(PROC_HOTKEY_INT_TO_STR, id_ctl)
</syntaxhighlight>

====dlg_proc - Signatures of event callbacks====

Callbacks must be in forms shown in the topic [[#Callback_parameter]].

Callbacks for "dlg_proc" must be declared as:

<syntaxhighlight lang="python">
# for functions
def my(id_dlg, id_ctl, data='', info=''):
  pass

# for class methods
class Command:
  def my(self, id_dlg, id_ctl, data='', info=''):
    pass
</syntaxhighlight>

Parameters:

* "id_dlg": Int handle of the form.
* "id_ctl": Int index of control. But for event "on_key_down" it has different meaning.
* "data": Value specific to event.
* "info": Additional value passed from CudaText, if extended form of callback is specified, with "info" part.

====dlg_proc - Actions====

Param "prop": it can be of any simple type (str, int, bool), also tuple/list (of any simple type), also dict (keys: str, values: simple type or tuple/list). Most used is dict. Example: prop={"cap": "...", "x": 10, "y": 10, "w": 600, "en": False}.

Param "id_dialog": int, form handle. Ignored only for DLG_CREATE action (pass 0 with it).

Possible values of "id_action":

* DLG_CREATE: Creates new empty form, returns form "handle". You must pass this handle (int) to next calls of dlg_proc().
* DLG_HIDE: Hides form.
* DLG_FREE: Hides and deletes form.
* DLG_SHOW_MODAL: Shows form in modal mode. Waits for form to hide, then returns.
* DLG_SHOW_NONMODAL: Shows form in non-modal mode. Returns immediately.
* DLG_FOCUS: Focuses form (in non-modal mode).
* DLG_SCALE: Scales form, with all controls, for the current OS high-DPI value. E.g. of OS scale is 150%, all will be scaled by 1.5.
* DLG_TO_FRONT: Puts form to the foreground (in Z-order of forms).

* DLG_PROP_GET: Returns form props, as dict. See example plugin, which props are returned.
* DLG_PROP_SET: Sets form props, from dict. Param "prop" is dict. Only props mentioned in "prop" are applied, other props don't change.

* DLG_DOCK: Docks (inserts) form into another form. Param "index" is handle of another form, and 0 means main CudaText form. Param "prop" can be: "L", "R", "T", "B" for sides left/right/top/bottom (default is bottom).
* DLG_UNDOCK: Undocks form from it's current parent form.

* DLG_LOCK: Disables updating of the form. This can be used before adding many controls at once, to remove flickering of these controls.
* DLG_UNLOCK: Enables updating of the form. This must be used in pair with DLG_LOCK.

* DLG_CTL_COUNT: Returns count of controls on form.
* DLG_CTL_ADD: Adds new control to form, returns its index, or None if cannot add. Param "prop" is type of control. See description in dlg_custom.
* DLG_CTL_PROP_GET: Returns control props, as dict. Control must be specified by name or index.
* DLG_CTL_PROP_SET: Sets control props.  Control must be specified by name or index. Param "prop" is dict with props. Only props mentioned in "prop" are applied, other props don't change. To "reset" some props, you must mention them with some value.
* DLG_CTL_FOCUS: Focuses control.  Control must be specified by name or index.
* DLG_CTL_DELETE: Deletes control.  Control must be specified by name or index. Controls are stored in list, so after a control deleted, indexes of next controls shift by -1. So don't use fixed indexes if you delete some, use DLG_CTL_FIND.
* DLG_CTL_DELETE_ALL: Deletes all controls.
* DLG_CTL_FIND: Returns index of control by name, or -1 if cannot find. Param "prop" is name.
* DLG_CTL_HANDLE: Returns int "handle" of control on a form. Control must be specified by name or index. This handle is currently useful for types:
** type "button_ex": pass handle to button_proc()
** types "editor"/"editor_edit"/"editor_combo": pass handle to Editor() constructor
** type "listbox_ex": pass handle to listbox_proc()
** type "paintbox": pass handle to canvas_proc()
** type "statusbar": pass handle to statusbar_proc()
** type "treeview": pass handle to tree_proc()
** type "toolbar": pass handle to toolbar_proc()

* DLG_CTL_TO_FRONT: Puts control to the foreground (in Z-order of controls).
* DLG_CTL_TO_BACK: Puts control to the background (in Z-order of controls).

* DLG_COORD_LOCAL_TO_SCREEN: Converts x/y coordinates from form-related, to screen-related. Param "index" is x, "index2" is y. Returns tuple (x,y).
* DLG_COORD_SCREEN_TO_LOCAL: Converts x/y coordinates from screen-related, to form-related. Param "index" is x, "index2" is y. Returns tuple (x,y).

* DLG_POS_GET_STR: Returns form position/size as string.
* DLG_POS_SET_FROM_STR: Sets form position/size from string. Param "prop" is string value.
** It is faster than setting form properties "x", "y", "w", "h", it makes single resize.
** String format is the same as in DLG_POS_GET_STR, comma-separated numbers "x,y,w,h", any number can be skipped to keep old value.

====dlg_proc - Anchors====

Anchor is attaching of control's side to another control, or to the parent form, so control is auto positioned, initially and on form resize. Lazarus IDE has such Anchor Editor dialog:

[[Image:Anchor_Editor_en.png]]

In this dialog you see, that all 4 sides of control attach to one of 3 sides of another control (or parent form).

* Anchors override absolute positions, e.g. anchor of left side overrides prop "x".
* Anchoring to invisible control is allowed.
* Anchoring circles (A to B to C to A) is not allowed, but should not give errors.

To change anchors of control, set its properties: a_l, a_r, a_t, a_b.
Initially left/top anchors are set (to the parent form).

Side value "[" aligns control to left/top side of target:

          +--------+
          | target |
          +--------+
  
          +--------------+
          |   control    |
          +--------------+

Side value "]" aligns control to right/bottom side of target:

           +--------+
           | target |
           +--------+
  
     +--------------+
     |   control    |
     +--------------+

Side value "-" centers control relative to target:

           +--------+
           | target |
           +--------+
  
        +--------------+
        |   control    |
        +--------------+

Useful information in the Lazarus wiki: [[Anchor_Docking#Why_use_Anchors_instead_of_Align.3F]].

Example: to attach "colorpanel" to the right side of form, clear left anchor (set to None), and add right/bottom anchors. This also sets spacing-aroung (padding) to 6 pixels.

<syntaxhighlight lang="python">
  #attach colorpanel to the right
  dlg_proc(id_form, DLG_CTL_PROP_SET, index=n, prop=
      { 'a_l': None, 'a_r': ('', ']'), 'a_b': ('', ']'), 'sp_a': 6  } )
</syntaxhighlight>

====dlg_proc - Example====

Params "w" and "h": if values>0, they are width and height of dialog.

Returns string if command selected, or None if cancelled.

===file_open===

 file_open(filename, group=-1, options="")
 file_open((filename1, filename2), group=-1, options="")

Opens editor tab with given filename. If filename already opened, activates its tab. Pass empty string to open untitled tab.

First parameter can be 2-tuple (or 2-list) of string, to open two files in a single tab, in a splitted view. In this case, second filename won't be handled specially for zip file, picture file, binary file etc.

Returns bool. True, if first filename is empty. Otherwise, returns True if first filename exists, and second filename is empty or exists.
For zip file (only first filename is checked for it), returns True only if zip file contains valid CudaText add-on, and it was installed.

* Param "group": index of tab-group, currently 0...8 (6 normal groups + 3 floating groups). Default means "current group". If you pass index of currently hidden group, group won't show, you need to call editor command to show it, see [[#cmd]].
* Param "options": string:
** If it has "/preview", then file opens in a "temporary preview" tab, with italic caption. Param "group" is ignored then, used 1st group.
** If it has "/nohistory", file's saved history (caret, scroll pos, etc) won't be used.
** If it has "/noloadundo", file's persistent-undo (additional file created by using option "undo_persistent") won't be loaded.
** If it has "/nolexerdetect", lexer won't be auto-detected.
** If it has "/noevent", then "on_open_pre" event won't fire.
** If it has "/noopenedevent", then "on_open" event won't fire.
** If it has "/nononeevent", then "on_open_none" event won't fire.
** If it has "/silent", then zipped add-on will install w/o prompt and report.
** If it has "/passive", then tab will not activate, it will be passive tab.
** If it has "/nonear", then app option "ui_tab_new_near_current" will be ignored, tab will append to end.
** If it has "/nozip", then .zip files will not be handled specially.
** If it has "/nopictures", then picture files will not be handled specially.

** If it has "/view-binary', then file will open in internal viewer, binary (fixed width) mode.
** If it has "/view-hex', then file will open in internal viewer, hex mode.
** If it has "/view-unicode', then file will open in internal viewer, unicode (variable width) mode.
** If it has "/nontext-view-text", then in the case of non-text file, file will open in internal viewer, text (variable width) mode.

** If it has "/nontext-view-hex", then in the case of non-text file, file will open in internal viewer, hex mode.
** If it has "/nontext-view-unicode", then in the case of non-text file, file will open in internal viewer, unicode mode.
** If it has "/nontext-view-uhex", then in the case of non-text file, file will open in internal viewer, unicode+hex mode.
** If it has "/nontext-cancel", then in the case of non-text file, function will fail and return False.

Note: "ed" is always the current editor, after file_open() current editor changes, and "ed" is the new cur editor.

Example opens untitled tab, and writes multi-line text to it:
<syntaxhighlight lang="python">
  file_open('')
  ed.set_text_all(text)
</syntaxhighlight>

===ed_handles===

 ed_handles()

Returns range object: it contains int handles of all editor tabs. Pass each handle to Editor() to make editor object from handle.

Example code, which shows filenames of all tabs:

<syntaxhighlight lang="python">
    #show all file names in console
    for h in ed_handles():
        e = Editor(h)
        print(e.get_filename())
</syntaxhighlight>

===ed_group===

* LEXER_REREAD_LIB: Re-reads lexer library from disk, updates lexer menu. Make sure that plugins' dialogs don't use editor with lexer, which may crash.

* LEXER_ADD_VIRTUAL: Adds virtual lexer, which doesn't have a file and doesn't highlight text, it's only an item in lexers list. The purpose of virtual lexers is to avoid creating lexer files, but allow plugins to be activated by some lexer name / some file types. Param "value" must be tuple of string: (lexer_name, file_types, line_comment, range_comment_begin, range_comment_end). Item file_types here must have the same notation as for "lite" lexers, e.g. "*.pas;*.pp;*.lpr". Virtual lexers are added to the "lite" lexers list, and show the same suffix in lexer menu. To activate such a lexer, call Editor.set_prop(PROP_LEXER_FILE, lexer_name+suffix). Action returns bool: lexer_name didn't exist, lexer was added.

=Editor class=

Editor class has methods to work with editor-controls.
Global object of Editor exist: "ed", it always refers to the currently focused editor in UI-tabs.

==Carets==
===Editor.get_carets===

 get_carets()

Returns list of 4-tuples, each item is info about one caret: (PosX, PosY, EndX, EndY).

* PosX is caret's column (0-base). Tab-chars give x increment 1, like others.
* PosY is caret's line (0-base).
* EndX/EndY is position of selection edge for this caret. Both -1 if no selection for caret.

Example shows text of first caret's selection:

<syntaxhighlight lang="Python">
    carets = ed.get_carets()
    x1, y1, x2, y2 = carets[0]
    if y2>=0:
        # sort (y,x) pairs
        if (y1, x1)>(y2, x2):
            x1, y1, x2, y2 = x2, y2, x1, y1
        s = ed.get_text_substr(x1, y1, x2, y2)
        msg_status('Selection: '+s)
</syntaxhighlight>

Controls carets. Possible values of "id":

* CARET_SET_ONE: Removes multi-carets and sets single caret with given position (posx, posy, endx, endy). To place caret without selection, set both "endx", "endy" to -1.
* CARET_ADD: Adds caret (multi-carets feature) with given position. Returns number of carets after that.
* CARET_DELETE_ALL: Deletes all carets. Note: you must add caret then to enable text editing to user.
* CARET_SET_INDEX + N, where N is 0...1e6: Changes single caret with index N to given position.
* CARET_DELETE_INDEX + N, where N is 0...1e6: Deletes single caret with index N.

Param "options" must be 0 or sum of the following flags:

Text can have any line-breaks (LF, CRLF, CR, mixed).

Notes:
* Function cannot work with read-only editor (see Editor.get_prop, Editor.set_prop and PROP_RO).
* Function looses Undo information. To support Undo, use another API to set text, e.g. Editor.replace().

Deletes range from position (x1, y1) to bigger position (x2, y2).

* Too big x1/x2 are allowed (after line-end)
* Too big y2 means delete to end of file

Note: don't pass tuple from get_carets()[0], this tuple has not sorted pos=(x1, y1), end=(x2, y2), you need to sort them (first sort by y, then by x).

Example replaces selection of 1st caret with text:

<syntaxhighlight lang="Python">
        x0, y0, x1, y1 = ed.get_carets()[0]
        if (y0, x0) >= (y1, x1): #note that y first
            x0, y0, x1, y1 = x1, y1, x0, y0

        ed.set_caret(x0, y0)
        ed.delete(x0, y0, x1, y1)
        ed.insert(x0, y0, text)
</syntaxhighlight>

===Editor.insert===

 insert(x, y, text)

Inserts given text at position (x, y). If y too big, appends block to end (even to final line w/out line-end).
Text can be multi-line, all CR LF are converted to currently used line-breaks.

Returns 2-tuple (x, y) of position after inserted text. It is on the same line, if text is single line. Returns None if cannot insert.

Replaces range from position (x1, y1) to bigger position (x2, y2), with new text.

* Too big x1/x2 are allowed (after line-end)
* Too big y2 means delete to end of file

Function does the same as delete+insert, but

* optimized for replace inside one line (when y1==y2 and no line-breaks in text)
* for multi-line it also makes grouped-undo for delete+insert

Returns 2-tuple (x, y) of position after inserted text.

===Editor.replace_lines===

 replace_lines(y1, y2, lines)

Deletes whole lines from index y1 to y2, then inserts new lines from specified list.

* Index y1 must be valid index (0 to count-1)
* Index y2 can be less than y1 (to not delete), and can be too big (to delete lines to end)
* Param lines is list/tuple of str. Can be empty list to just delete lines. Inside items should not be "\n" and "\r": "\n" will generate additonal lines, "\r" not handled.

Returns bool: index y1 correct, replace done.

Note: listbox disappears if you move caret or type text, unlike usual auto-completion listboxes (they can recalculate items for new caret pos).

===Editor.complete_alt===

 complete_alt(text, snippet_id, len_chars, selected=0)

Shows alternative completion listbox. This allows to insert complex snippets, not only simple words.

Function returns None and listbox stays open. When user chooses listbox item, event "on_snippet" is called in plugin.

Function params:

* Param "text": "\n"-separated lines, one line per snippet. Each line has 3 columns "\t"-separated.
** Column 1 is shown on left side of listbox (good to show here name of function)
** Column 2 is shown on right side of listbox (good to show here type of function)
** Column 3 is snippet text in any format. Can contain "\t" but not "\n". Can have any chars escaped in any form.
* Param "snippet_id": Some short string just to identify snippet between different plugins. Different plugins provide snippets in different formats, they must  insert only their own snippets, so each plugin must check kind of the snippet, passed to "on_snippet" event.
* Param "len_chars": Listbox is shown lefter than the caret, by specified count of chars.
* Param "selected": Index of initially selected listbox item (0-based).

After user has chosen some item in the completion listbox, event "on_snippet" will be called with parameters:

* Param "snippet_id": Value from complete_alt() call.
* Param "snippet_text": Text of chosen snippet.

===Editor.gap===

 gap(id, num1, num2, tag=-1, size=0, color=COLOR_NONE)

Performs action on inter-line gaps (they don't overlap text above/below).
Possible values of "id":

* GAP_GET_ALL: Returns list of gaps, as list of dict. Dict keys are:
** "line": int: Line index; or -1 for gap before the first line.
** "tag": int: Tag.
** "size": int: Height in pixels.
** "color": int: Color.
** "bitmap": 2-tuple of int: Size of bitmap, or (0, 0) if no bitmap.

* GAP_MAKE_BITMAP: Action is needed only if you want to paint bitmap in gap, it's not needed for empty gaps. Makes new bitmap for future gap. Size of bitmap is (num1, num2). Returns 2-tuple (id_bitmap, id_canvas).
** "id_bitmap": bitmap handle, needed to later call GAP_ADD.
** "id_canvas": canvas handle, needed to paint on bitmap, by canvas_proc().

* GAP_ADD: Adds gap to editor. Returns bool: params correct, gap added. Params:
** "num1": int: Line index; can be -1 for gap before the first line.
** "num2": int: If 0, gap will be empty; otherwise it is bitmap handle (id_bitmap), which you got from GAP_MAKE_BITMAP.
** "tag": int: Some value, to separate gaps from several plugins.
** "size": int: If >0, it is gap height in pixels. If 0, gap height is calculated from bitmap handle.
** "color": int: If not COLOR_NONE, then it's gap background color.

* GAP_DELETE: Deletes gaps, for line indexes from num1 to num2.
* GAP_DELETE_ALL: Deletes all gaps.

Example plugin:

<syntaxhighlight lang="python">
from cudatext import *
class Command:
    def run(self):
        for i in range(ed.get_line_count()//2):
            self.do_gap(i*2)

    def do_gap(self, num):
        id_bitmap, id_canvas = ed.gap(GAP_MAKE_BITMAP, 600, 50)
        canvas_proc(id_canvas, CANVAS_SET_BRUSH, color=0xa0ffa0)
        canvas_proc(id_canvas, CANVAS_POLYGON, '200,0,300,30,200,50')
        canvas_proc(id_canvas, CANVAS_SET_BRUSH, color=0xffffff, style=BRUSH_CLEAR)
        canvas_proc(id_canvas, CANVAS_TEXT, x=230, y=10, text='gap %d'%(num+1))
        canvas_proc(id_canvas, CANVAS_SET_BRUSH, color=0xffffff, style=BRUSH_SOLID)
        ed.gap(GAP_ADD, num, id_bitmap)
</syntaxhighlight>

===Editor.dim===

 dim(id, index=0, index2=0, value=100)

Controls dim (shade, fade) ranges, which blend text font color with background color. Dim value is 0..255, 0 means "no effect", 255 means "text is transparent".

Possible values of "id":

* DIM_ADD: Adds new range.
** Param "index": index of first range line (0-base).
** Param "index2": index if last range line (value bigger than line count is allowed).

Performs some action in editor. Possible values of "id":

* EDACTION_UPDATE: Repaint editor.
** "param1": Can be empty or "0" or "1". If "1", WrapInfo internal structure will be updated. WrapInfo update is needed after text changes, if program did not detect that changes automatically (in this case simple repaint will be incorrect).

* EDACTION_UNDOGROUP_BEGIN, EDACTION_UNDOGROUP_END: Begins/ends an undo-group. Text editions, which are enclosed in undo-group, are handled by Undo/Redo command in a single step. Other text editions are handled in a single or multiple steps, it depends on CudaText option.

* EDACTION_FIND_ONE: Perform text search, get match as 4-tuple of int (start_x, start_y, end_x, end_y) or None if not found. This uses finder independent from CudaText Find/Replace dialog, you must configure this finder via options string.
** "param1": Search string.
** "param2": Search options, see [[#Finder_options_as_string]].
** Note: returns False for incorrect RegEx.

* EDACTION_REPLACE_ONE: Perform text search+replace, get match as 4-tuple of int (start_x, start_y, end_x, end_y) or None if not found. This uses finder independent from CudaText Find/Replace dialog, you must configure this finder via options string.

** "param3": Search options, see [[#Finder_options_as_string]].
** Note: returns False for incorrect RegEx.

* EDACTION_REPLACE_ALL: Perform text search+replace in the entire document (note: ignoring caret position), get count of replacements. This uses finder independent from CudaText Find/Replace dialog, you must configure this finder via options string.
** "param1": String to find.
** "param2": String to replace with.
** "param3": Search options, see [[#Finder_options_as_string]].
** Note: returns False for incorrect RegEx.

* EDACTION_FIND_ALL: Perform text search and get all matches in a list. Result list items are 4-tuples of int: (start_x, start_y, end_x, end_y). This uses finder independent from CudaText Find/Replace dialog, you must configure this finder via options string.
** "param1": Search string.
** "param2": Search options, see [[#Finder_options_as_string]].
** "param3": Optional. Maximal line length (default is 0x7FFFFFFF). Lines longer than this value will be skipped during search.
** Note: returns False for incorrect RegEx.

* EDACTION_FIND_BRACKETS: Find position of nearest opening bracket with its pair bracket. Returns 4-tuple (col_start, line_start, col_end, line_end), where line_end<0 if brackets not found.
** "param1": Text position as 2-tuple (column, line).
** "param2": String with allowed bracket pairs. Can have these pairs: () [] {} <>.
** "param3": Max distance, in lines, to the pair bracket. Must be 32-bit signed int.

* EDACTION_SHOW_POS: Make text position visible without caret moving. Returns True if params correct and scrolling occured, returns False if params correct and no scrolling occured, returns None if params not correct.
** "param1": Text position as 2-tuple (column, line).
** "param2": Indentation of text position from edges as 2-tuple (indent_horz, indent_vert). Values meaning is like for CudaText options "find_indent_horz", "find_indent_vert".

* EDACTION_CODETREE_FILL: Fill some visual TreeView control (it can be standard code-tree control, or TreeView control in some form) with editor's code-tree information. Param "param1" must be TreeView handle (to use with tree_proc()). Returns True if lexer is set and information is read, otherwise False.

* EDACTION_LEXER_SCAN: Run lexer parsing (if lexer is set) from line index, given by "param1". Waits until parsing finishes.

* EDACTION_EXPORT_HTML: Create HTML file from editor's text with syntax highlighting. Returns bool: file is created. Param "param1" must be dict with the following keys:
** "file_name": str: Full path of file.
** "title": str: HTML page title.
** "font_name": str: Font name.
** "font_size": int: Font size, in HTML points.
** "with_numbers": bool: Show gutter with line numbers.
** "color_back": int: RGB color of page background.

** "param3": RGB color of column background, or COLOR_NONE for default themed color.

* MICROMAP_DELETE: Delete micromap column by its tag. Param "param1": tag. Returns bool: column was found and deleted.

=TreeHelpers=

CudaText contains built-in support for TreeHelpers. They build code-tree for additional lexers. TreeHelpers must be plugins, which have special install.inf file (Ini format).

Section "info":
* key "subdir" must begin with "cuda_tree_"

Section(s) "treehelper" followed by any string (e.g. "treehelper1"):
* key "lexers" is comma-separated lexers list
* key "method" is name of getter method in __init__.py

File __init__.py must contain getter method(s), referenced by install.inf. Getter has signature (with any name):

 def get_headers(filename, lines)

* param "lines" is list of str, editor contents in CudaText.
* param "filename" is full file path, it is to support included files or something.

Getter must return list of tuples: (pos, level, caption, icon).

* field "pos": tuple of int (x1, y1, x2, y2): range for tree node.
* field "level": 1-based level of node, node of level K+1 is nested into (nearest upper) node of level K.
* field "caption": caption of node.
* field "icon": 0-based index of icon from standard imagelist, or -1 if icon not used.
** 0: folder
** 1: parts1
** 2: parts2
** 3: parts3
** 4: box
** 5: func
** 6: arrow1
** 7: arrow2

Getter can also return value not of "list" type, in this case CudaText will not update the code-tree.

TreeHelpers can be written in Pascal too. This way they will work much faster.
To write/debug a TreeHelper in Pascal, use the project "treehelpertester" in the CudaText GitHub repo.
These TreeHelpers were rewritten from Python to Pascal and are built-in now:

* Markdown
* MediaWiki
* reST

=Linters=

Linters are 2nd-level plugins for CudaLint plugin. CudaLint was ported from SublimeLinter 3, and its linters should be ported from SublimeLinter linters.
Here is example:

* Original linter: https://github.com/SublimeLinter/SublimeLinter-javac
* Ported linter: https://github.com/cudatext-addons/cuda_lint_javac

To see how to port, compare files "linter.py". Other files must be added like in other CudaLint linters.

=Tech info=

==Format of text for cmd_MouseClick==

Text is "X,Y" where X/Y are position of caret relative to top-caret (other carets removed when command runs). If Y is 0, X is addition to caret's x.
If Y not 0, Y is addition to caret's y, and X is absolute caret's x.

==Finder options as string==

Some APIs allow to specify finder options as a string. Such string can have the following chars:

* "b": Backward search
* "c": Case sensitive
* "r": Regular expression
* "w": Whole words
* "f": Search from caret
* "s": Search in selection
* "o": Confirm replaces
* "a": Wrap search at edge of text
* "T" followed by a digit: Allowed syntax elements. Digit can be:
** "0": any
** "1": only comments
** "2": only strings
** "3": only comments/string
** "4": except comments
** "5": except strings
** "6": except comments/strings

==Format of text for cmd_FinderAction==

Text is chr(1) separated items:

* item 0: Finder action, one of:
** "findfirst": Find first
** "findnext": Find next
** "findprev": Find previous
** "rep": Replace next, and find next
** "repstop": Replace next, and don't find
** "repall": Replace all
** "findcnt": Count all
** "findsel": Find all, make selections
** "findmark": Find all, place markers
* item 1: Text to find
* item 2: Text to replace with
* item 3: Options string, see [[#Finder_options_as_string]]

==Format of serialized Undo==

Text is "\n"-separated undo/redo items. Each line is tab-separated elements:

* editing action, number 0..5:
** 0: line changed
** 1: end-of-line mark changed
** 2: line inserted
** 3: line deleted
** 4: cleared document "modified" flag
** 5: mouse clicked
* index of changed line (not for mouse clicks), 0-based.
* end-of-line kind, number 0..3:
** 0: none
** 1: CRLF
** 2: LF
** 3: CR
* line state, number 0..3:
** 0: none
** 1: changed
** 2: added
** 3: saved
* caret position(s). "x0,y0;" + "x1,y1;" + "x2,y2;" + ... ie 2*N numbers for N carets.
* soft mark flag, number 0/1 (boolean). Logic of soft/hard marks is described in wiki page [[ATSynEdit]].
* hard mark flag, number 0/1.
* line text, in UTF8. This text can have tab-chars, tab-char is not separator.

Note that field "line state" was inserted in API 1.0.328, new format of data became incompatible with old format.

=API of 3rd-party plugins=
==API of Options Editor==
Options Editor plugin (preinstalled in CudaText) has API which allows to call its dialog with custom options. Example shows dialog with 4 custom options, with custom title. Options which user changed in dialog will be saved to user.json or lexer-specific config.

<syntaxhighlight lang="Python">
import os
import cudax_lib as appx
import cuda_options_editor as op_ed

fn_config = 'cuda_my_plugin.json' # without path!
meta_info = [
        {
            "opt": "my_opt_1",
            "cmt": ["Comment line 1",
                    "Comment line 2",
                    "Comment line 3"],
            "def": True,        # Default value
            "frm": "bool",      # Value type from
                                #   bool float int str - simple types
                                #   font - font name
                                #   font-e - font name or empty
                                #   hotk - hotkey
                                #   file - file path
                                #   strs  - list of str
                                #   int2s - dict int to str
                                #   str2s - dict str to str
            "chp": "MySection"  # Section (can be empty)
        },
        {   "opt": "my_opt_2",
            "cmt": ["Comment"],
            "def": "v1",
            "frm": "strs",
            "lst": ["v1", "v2"]
        },
        {   "opt": "my_opt_3",
            "cmt": ["Comment"],
            "def": 11,
            "frm": "int2s",
            "dct": [[11, "value for 11"], [22, "value for 22"]]
        },
        {   "opt": "my_opt_4",
            "cmt": ["Comment"],
            "def": "a",
            "frm": "int2s",
            "dct": [["a", "value for a"], ["b", "value for b"]]
        }
        ]

class Command:
    def get_opt(path, val):
        return appx.get_opt(path, val, user_json=fn_config)

    def config(self):
        subset = '' # section in user.json, if user.json is used
        title = 'My Plugin Options'
        how = {'hide_lex_fil': True, 'stor_json': fn_config}
        op_ed.OptEdD(
            path_keys_info = meta_info,
            subset = subset,
            how = how
            ).show(title)
        do_load_plugin_options() # some plugin function to reread options
</syntaxhighlight>

This will show:

[[File:cudatext_options_editor.png]]

Options Editor stores values in JSON with trailing comma, so to read these options, plugin must use cudax_lib.get_opt() instead of json.load().

==API of Project Manager==
Project Manager plugin (preinstalled in CudaText) gives API to read properties of currently opened project. It has global variable '''global_project_info''', which is dict with keys:

* "filename": Path of project file (*.cuda-proj), or empty string if project is not saved.
* "mainfile": Path of "main file" (which must be set by user from Project Manager context menu).
* "nodes": List of root project nodes, ie folder and file paths in the root level.
* "vars": List of variables defined in the Project Properties dialog. List of strings in the form "name=value".

Example gets list of root project items:
<syntaxhighlight lang="Python">
     import cuda_project_man as p
     nodes = p.global_project_info['nodes']
</syntaxhighlight>

Result without opened project:

<syntaxhighlight lang="Python">
  >>> p.global_project_info
  {'filename': '', 'nodes': [], 'vars': [], 'mainfile': ''}
</syntaxhighlight>
 
Result with opened folder in unsaved project:

<syntaxhighlight lang="Python">
  >>> p.global_project_info
  {'filename': '', 'nodes': ['/home/name/datadir'], 'vars': [], 'mainfile': ''}
</syntaxhighlight>

Result with opened folder in saved project:

<syntaxhighlight lang="Python">
  >>> p.global_project_info
  {'filename': '/home/name/test.cuda-proj', 'nodes': ['/home/name/datadir'], 'vars': [], 'mainfile': ''}
</syntaxhighlight>

Also global function '''project_variables()''' exists, which is handy wrapper around global_project_info. It returns dict with keys:

* "ProjDir": Folder of project file (*.cuda-proj).
* "ProjMainFile": Path of "main file".
* "ProjMainFileNameOnly": Only name of "main file", without path.
* "ProjMainFileNameNoExt": Name of "main file", without path and extension.
* Additional keys for project variables.

Its code currently is:

<syntaxhighlight lang="Python">
def project_variables():
    res = collections.OrderedDict()
    data = global_project_info
    res['ProjDir'] = os.path.dirname(data.get('filename', ''))

    fn = data.get('mainfile', '')
    res['ProjMainFile'] = fn
    res['ProjMainFileNameOnly'] = os.path.basename(fn)
    res['ProjMainFileNameNoExt'] = '.'.join(os.path.basename(fn).split('.')[0:-1])

    data = global_project_info.get('vars', [])
    for item in data:
        s1, s2 = item.split('=', maxsplit=1)
        res[s1] = s2
    return res
</syntaxhighlight>

=Questions=

==How plugin can fill code-tree==

* Handle events on_open, on_focus, on_change_slow (better don't use on_change, it slows down the app)
* Get handle of code-tree: h_tree = app_proc(PROC_GET_CODETREE, "")
* Fill tree via tree_proc(h_tree, ...)
** Disable standard tree filling via ed.set_prop(PROP_CODETREE, False)
** Clear tree via tree_proc(h_tree, TREE_ITEM_DELETE, id_item=0)
** On adding tree items, set range for them via tree_proc(h_tree, TREE_ITEM_SET_RANGE...)

==How plugin can show tooltips on mouse-over==

* Create dialog for tooltip, via dlg_proc()

* Handle events on_open, on_focus, on_change_slow (better don't use on_change, it will slow down the app)
** Find text regions which need tooltip
** Delete old hotspots via ed.hotspot(HOTSPOT_DELETE_BY_TAG...)
** Add hotspots via ed.hotspots(HOTSPOT_ADD...)

* Handle event on_hotspot
** Find which text region is under cursor
** Fill dialog via dlg_proc()
** Set dialog prop "p" to the handle of editor, ed_self.h. Don't use ed.h, because it is virtual handle 0.
** Set dialog pos (props "x", "y") to editor-related pixel coords. It is complex. See example: plugin HTML Tooltips.
** Show dialog via dlg_proc(..., DLG_SHOW_NONMODAL)
* On exiting hotspot, hide dialog

==How to make auto-completion plugin==

Good example is "HTML Class Complete": https://github.com/CudaText-addons/cuda_html_class_complete

* Use CudaText menu item "Plugins / Make Plugin" to create empty plugin. In the "Make Plugin" dialog, check event "on_complete", so method Command.on_complete is called when user pressed Ctrl+Space.

* Plugin files are located in the "py/cuda_nnnn" folder. In install.inf, add line "lexers=NNNN" for the event on_complete, so event is called only for lexer NNN.

* In plugin .py file, in method on_complete, read editor text via ed.get_text_all() or ed.get_text_line(), read caret position via ed.get_carets(), make the completions list.

* Call ed.complete() or ed.complete_alt() to show completions list.
