=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 events, add method to class Command (like methods of command plugin). E.g. method "on_save" will be called by editor event "on_save". Event methods have param "ed_self": Editor object in which event occured (this object is the same as "ed" in 99% cases, but in some cases event occurs in inactive editor, e.g. "Save all tabs" calls "on_save" for inactive tabs).

Usually methods returns None, sometimes they can return True or False to block the default  handler. The False result blocks propagation of event to other plugins, so don't return False if not nessesary.

==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.
* on_close_pre(self, ed_self): Called before closing tab, before checking if tab modified or not. Method can return False to disable closing.
* on_close(self, ed_self): Called before closing tab, after modified file was saved, and editor is still active.
* on_save_pre(self, ed_self): Called before saving file. Method can return False to disable saving, other value is ignored.
* on_save(self, ed_self): Called after saving file.
* on_start(self, ed_self): Called once on program start (ignore ed_self).
* on_exit(self, ed_self): Called on exiting application. This event is lazy, ie it's called only for already loaded plugins.

==Tabs==

* on_tab_change(self, ed_self): Called after active tab is changed.
* on_tab_move(self, ed_self): Called after closing a tab (another tab is already activated), or moving a tab (by drag-n-drop, or UI command).
* on_tab_switch(self, ed_self, next, state): Called on running commands "switch active tab to next" (with next=True) and "switch active tab to prev" (with next=False). Param "state": same as in "on_key". Method must return True to skip default tab-switcher code.

==Editor==

* on_change(self, ed_self): Called after editor text is changed.
* on_change_slow(self, ed_self): Called after editor text is changed, and few seconds (option) passed. Used in CudaLint plugin, it needs to react to change after a delay.
* on_caret(self, ed_self): Called after editor caret position and/or selection is changed.
* on_insert(self, ed_self, text): Called before inserting a text. Method can return False to disable insertion, other return value is ignored.
* on_key(self, ed_self, key, state): Called when user presses a key in editor. Param "key" is int key code; values are listed in the module cudatext_keys. Param "state" is string of chars: "a" if Alt pressed, "c" if Ctrl pressed, "s" if Shift pressed, "m" if Meta (Windows-key) pressed. Method can return False to disable key processing, other return value is ignored.
* on_key_up(self, ed_self, key, state): Called when user depresses a key in editor. Params meaning is the same as in "on_key". Currently called only for Ctrl/Shift/Alt keys (to not slow down).
* on_focus(self, ed_self): Called after any editor gets focus.
* on_lexer(self, ed_self): Called after any editor's lexer is changed.
* on_paste(self, ed_self, keep_caret, select_then): Called before some Clipboard Paste command runs. Parameters are options of various paste commands. Method can return False to disable default operation.
* on_scroll(self, ed_self): Called on scrolling in editor.
* on_mouse_stop(self, ed_self, x, y): Called when mouse cursor stops (for a short delay) over editor. Params "x", "y" are mouse editor-related coords.
* on_hotspot(self, ed_self, entered, hotspot_index): Called when mouse cursor moves in/out of hotspot. See ed.hotspots() API.
* on_state(self, ed_self, state): Called after some app state is changed. Param "state" is one of EDSTATE_nnnn or APPSTATE_nnnn constants.
* on_snippet(self, ed_self, snippet_id, snippet_text): Called when user chooses snippet to insert, in ed.complete_alt() call.

==Editor clicks==

* on_click(self, ed_self, state): Called after mouse click on text area. Param "state": same meaning as in on_key.
* on_click_dbl(self, ed_self, state): Called after mouse double-click on text area. Param "state": same meaning as in on_key. Method can return False to disable default processing.
* on_click_gutter(self, ed_self, state, nline, nband): Called on mouse click on gutter area. Param "state": same as in on_key. Param "nline": index of editor line. Param "nband": index of gutter band. Method can return False to disable default processing.
* on_click_gap(self, ed_self, state, nline, ntag, size_x, size_y, pos_x, pos_y): Called after mouse click on inter-line gap: see Editor.gap(). Param "state": same meaning as in on_key. Other params: properties of clicked gap.

==Smart commands==

* on_complete(self, ed_self): Called by auto-completion command (default hotkey: Ctrl+Space). Method should call Editor.complete API. Method must return True if it handled command, otherwise None.  
* on_func_hint(self, ed_self): Called by function-hint command (default hotkey: Ctrl+Shift+Space). Method must return function-hint string (comma-separated parameters, brackets are optional). Empty str or None means no hint found.
* on_goto_def(self, ed_self): Called by go-to-definition command (in editor context menu). Method must return True if it handled command, otherwise None.

==Panels==

* on_console(self, ed_self, text): Called on entering text command in Python Console panel. Method can return False to disable internal command processing, other value is ignored. Ignore ed_self.
* on_console_print(self, ed_self, text): Called on adding line to Python Console memo. Also called on "print" commands. Method can return False to disable standard output to the Console panel. Ignore ed_self. Also called when app_log() clears console memo - with param text=None.
* on_console_nav(self, ed_self, text): Called on double-clicking line, or calling context menu item "Navigate", in Python Console panel. Ignore ed_self. Param "text" is line with caret.
* on_output_nav(self, ed_self, text, tag): Called on clicking line, or pressing Enter, in the Output or Validate panel. Ignore ed_self. 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.

==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 prior=0. So for any event, if 2+ plugins have this event, they're called in order on module names (e.g. cuda_aa, then cuda_dd, then cuda_mmm).

You may want to handle some event first.
To change prior 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 prior. So first called "on_key" with maximal number of "+", last called "on_key" w/o "+".

==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 param=

Callback parameter is supported in several API functions: dlg_proc, timer_proc, menu_proc, button_proc (maybe more later).

Parameter can be in these forms:

* callable, i.e. name of a function
* 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'.

=Global funcs=

===version===

 app_exe_version()

Gets version of program (string).

 app_api_version()

Gets version of API (string, contains 3 numbers, dot-separated).

Example of version check:

<syntaxhighlight lang="python">
  from cudatext import *
  
  if app_api_version() < '1.0.140':
      msg_box('Plugin NN needs newer app version', MB_OK+MB_ICONWARNING)
</syntaxhighlight>

====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. They also aren't sync'ed if user runs some search command via Command Palette or hotkey (e.g. "find current word, previous").

* 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.

====Side panel====

* PROC_SIDEPANEL_ADD_DIALOG: Adds tab, with embedded dialog, to sidebar. Gets bool: params correct, tab was added. Text must be 3-tuple (tab_caption, id_dlg, icon_filename):
** Caption of tab (must not contain ",")
** Handle of dialog, from dlg_proc()
** Name of icon file (must not contain ",")

* PROC_SIDEPANEL_REMOVE: Removes tab. Text is caption of tab. (Note: actually it hides tab, dialog for this tab is still in memory). Gets bool: tab was found/removed.
* PROC_SIDEPANEL_ACTIVATE: Activates tab in sidebar. Gets bool: tab was found/activated. Text can be:
** str: tab_caption.
** 2-tuple (tab_caption, bool_set_focus). Default for bool_set_focus is False.

* PROC_SIDEPANEL_GET_CONTROL: Gets int handle of dialog, inserted into tab. Text is caption of tab. Gets None if cannot find tab.

Notes:

* Name of icon file: name of png/bmp file. Icon size should be equal to size of current sidebar icon set, it's default is 20x20 (to detect size of icon set, you can read and parse CudaText option). If filename is without path, CudaText sub-dir "data/sideicons" is used (so only a standard icon name can be without path).

* If get_dict=False, gets 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.

====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 modal/nonmodal, controls can change value during form showing.

If an action needs control, you can use 2 ways: 
* set param "name" to control's name (name is searched if not empty), 
* set param "index" to control's index (you should use DLG_CTL_FIND to find it).

====Types====

Possible types of UI controls are described in dlg_custom, see [[#Types]]. Additional types only for dlg_proc:

* "button_ex": button, application-themed, works via button_proc()
* "editor": full featured editor, works via Editor class
* "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()

====Form properties====

* "cap": str: Caption of form.
* "x", "y": int: Position (screen coordinates), left/top.
* "w", "h": int: Size, width/height.
* "w_min", "w_max": int: Constraints for width, min/max value.
* "h_min", "h_max": int: Constraints for height, min/max value.
* "tag": str: Any string, set by plugin. 
* (deprecated) "resize": bool: Sets border of form to "resizable" style.
* "border": int: Sets border of form, DBORDER_nnn constants. Don't specify it together with deprecated "resize".
* "topmost": bool: Makes form stay on top of other forms in CudaText.
* "vis": bool: Visible state.
* "color": int: Background color.
* "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.

====Form events====

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 '')+\

====Callbacks====

Values of events are callbacks, must be in one of these forms: [[#Callback_param]].

Callbacks for dlg_proc must be declared as:

<syntaxhighlight lang="python">
#function
def my(id_dlg, id_ctl, data='', info=''):
  pass
#method
class Command:
  def my(self, id_dlg, id_ctl, data='', info=''):
    pass
</syntaxhighlight>

Parameters:

* id_dlg: Int handle of form.
* id_ctl: Int index of control. Used only for control events.
* data: Value, specific to event.
* info: Value from extended form of callback string.

====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 (pass 0).

Possible values of id_action:

* DLG_CREATE: Creates new empty form, gets 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_PROP_GET: Gets 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_CTL_COUNT: Gets count of controls on form.
* DLG_CTL_ADD: Adds new control to form, gets its index, or None if cannot add. Param "prop" is type of control. See description in dlg_custom.
* DLG_CTL_PROP_GET: Gets 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: Gets index of control by name, or -1 if cannot find. Param "prop" is name.
* DLG_CTL_HANDLE: Gets 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()
** type "editor": 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_COORD_LOCAL_TO_SCREEN: Converts x/y coordinates from form-related, to screen-related. Param "index" is x, "index2" is y. Gets 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. Gets tuple (x,y).

====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    |
        +--------------+

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>

====Example====

** If it has "/nohistory", file's saved history (caret, scroll pos, etc) won't be used.
** If it has "/noevent", then "on_open_pre" 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 "/view-text', then file will open in internal viewer, text (variable width) mode.

* ed_con_log: refers to log field (multi-line) in the "Console" panel.
* ed_con_in: refers to input field (single line) in the "Console" panel.

==Carets==
===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.

===set_caret===

Controls carets. Possible values of id:

* CARET_SET_ONE: Removes multi-carets and sets single caret with given coords (posx, posy, endx, endy). 
* CARET_ADD: Adds caret (multi-carets feature) with given coords. Also gets count of carets after that (same as len(get_carets()) ).
* CARET_DELETE_ALL: Removes all carets. (Note: you must add caret then to enable text editing to user.)
* CARET_SET_INDEX + N (any N>=0): Changes single caret with index N to given coords.

==Text read/write==

===get_text_all===

 get_text_all()

Gets entire text in the editor, as str.
Gives "\n" as line-breaks.

===set_text_all===

 set_text_all(text)

Sets entire text in the editor, to given str.
Text can have any line-breaks, they will be converted to currently used line-breaks.
It cannot work with read-only editor (see get_prop/set_prop and PROP_RO).

===get_text_line===

 get_text_line(index)

Gets single line (str) with given index (0-based).
Gets None if index incorrect.

===set_text_line===

 set_text_line(index, text)

Sets single line (str) with given index (0-based).
Text must be without line-breaks.
To add new line, pass index=-1.

===get_text_substr===

 get_text_substr(x1, y1, x2, y2)

Gets substring from position (x1, y1) to bigger position (x2, y2).

===delete===

 delete(x1, y1, x2, y2)

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>

===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.

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

===replace===

 replace(x1, y1, x2, y2, text)

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

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

===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.

If Y not 0, Y is addition to caret's y, and X is absolute caret's x.

==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

=FAQ=

==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 formatter plugin?==

* Fork plugin CSS Format (or JS Format). It has most of code done. It has 3 commands done: Format, Config global, Config local.
* Replace/delete its CSS (JS) modules
* Change options filename, change loading of options
* Change contents of func do_format()
