<hr><a name="activate"></a><h3><tt>geany.activate ( tab_id )</tt></h3><p>
Activates the document specified by <tt><b>tab_id</b></tt>.
</p>
<p>
If <tt><b>tab_id</b></tt> is a number, it activates the document at that index.
A <i>positive</i> number refers to the internal document array, and a <i>negative</i>
number refers to the (absolute) GtkNotebook index.<br>
Note that the indices begin at <tt>(1)</tt> and <tt>(-1)</tt> respectively.
</p>
<p>
If <tt><b>tab_id</b></tt> is a string, the function will try to activate the
notebook tab whose filename matches that string.<br>
( The full pathname is required! )

Returns the rightmost filename portion of <tt>pathstr</tt>, with the directory portion removed.
</p><br><br>
<hr><a name="batch"></a><h3><tt>geany.batch ( start )</tt></h3><p>
This function marks the beginning or ending of a group of operations<br>
that you want the user to be able to undo in a single step.</p>
<p>
If the <tt><b>start</b></tt> argument is <tt><b>true</b></tt>,
it marks the <i>beginning</i> of a group of operations.</p>
<p>
If the <tt><b>start</b></tt> argument is <tt><b>false</b></tt>,
it marks the <i>ending</i> of a group of operations.
</p><br><br>

When called with no arguments, returns the numeric value of the character at
the current caret position.</p><p>
When called with a numeric <tt><b>position</b></tt> argument, returns the
value of the character at that position.
</p><br><br>
<hr><a name="caret"></a><h3><tt>geany.caret ( [position] )</tt></h3><p>
When called with no arguments, returns the current caret position.</p>
<p>
When called with a single numeric argument, moves the caret to that position.<br>
Out-of-range values are adjusted to the nearest possible position (i.e. the start or end of the document.)
</p><br><br>
<a name="close"></a><hr><h3><tt>geany.close ( [filename]|[index] )</tt></h3>
<p>
When called with no arguments, closes the currently active document.
</p>
<p>
When called with a numeric argument, closes the file of that document index.
</p>
<p>
When called with a string argument, it will close that named document.
</p>
<p>
If the document has unsaved changes, the user will be prompted to save before closing,<br>
and will also be given the option to cancel the operation. To avoid this, you might <br>
want to consider using the <tt>geany.save()</tt> function beforehand.
</p>
<p>
Returns <tt><b>true</b></tt> if the document was successfully closed, or <tt><b>false</b></tt> otherwise.</p>
<br><br>
<hr><a name="copy"></a><h3><tt>geany.copy ( [content]|[start,stop] )</tt></h3><p>
When called with no arguments, copies the current selection to the clipboard.
</p><p>

</p>
<p>
When called with two arguments, copies the portion of the current document's text
that lies between the <tt><b>start</b></tt> and <tt><b>stop</b></tt> positions.
(Both positions must be positive numbers.)
</p>
<p>
Returns the number of characters copied, or <tt><b>nil</b></tt> if there is no open document.
</p>
<br><br>
<hr><a name="count"></a><h3><tt>geany.count ()</tt></h3><p>

</p><br><br>
<a name="dirlist"></a><hr><h3><tt>geany.dirlist ( path )</tt></h3><p>
Returns an iterator function that will be called once for each entry (file or subdirectory) in the specified folder.
The iterator produces only the name of each entry, and in no particular order.</p><p>
This function will generate an error dialog if the specified folder does not exist or cannot be accessed.
</p><br><br>
<a name="dirname"></a><hr><h3><tt>geany.dirname ( pathstr )</tt></h3><p>
Returns the directory portion of <tt>pathstr</tt>, with the rightmost filename portion removed.
</p><br><br>
<hr><a name="documents"></a><h3><tt>geany.documents ( [doc_id] )</tt></h3><p>
When called with a numeric argument, returns the full path and filename of <br>
the document at the index specified by <tt><b>doc_id</b></tt>.
</p>
<p>
When called with a string argument, returns the numeric index of the document with the<br>
path/filename that matches the <tt><b>doc_id</b></tt> string.<br>
</p>
<p>
Either of the two forms above may also return <tt><b>nil</b></tt> if the argument cannot be matched.</p>
<p>
Note: The <i>index</i> here refers to the editor's internal document array,
and might not be <br>
the same as the notebook tab index, since the tabs can be re-ordered by the user.
</p>
<p>
<br><br>
When called with no arguments, the function returns an iterator to list the full path and filename
of each document currently open in the editor.</p><p>
For example:</p>
<pre>
for filename in geany.documents()
do
print(filename)
end
</pre>
<br><br>
<a name="filename"></a><hr><h3><tt>geany.filename ()</tt></h3><p>
Returns the full path and filename of the current Geany document.</p><p>
If there is no open document, or if the current document is untitled, returns <tt><b>nil</b></tt>.
</p><br><br>
<a name="fileinfo"></a><hr><h3><tt>geany.fileinfo ()</tt></h3><p>
Returns a Lua table containing various information about the current document.<br>
If there is no open document, returns <tt><b>nil</b></tt>.
</p><p>
The returned table contains the following fields:

<br><br>
<a name="find"></a><hr><h3><tt>geany.find ( phrase, start, stop, options )</tt></h3><p>
Searches within the current document for the string <tt>phrase</tt>, beginning at <br>
the numeric <tt>start</tt> position and ending at the <tt>stop</tt> position.<br>
( To search backwards, specify a <tt>start</tt> value greater than <tt>stop</tt> . )<br><br>
</p><p>
The <tt>options</tt> argument is a table, each element may be one of the following strings:<br>
<table border="0" summary="search options">
<tr><td width="3%"> </td><td width="20%"><tt>
"matchcase"</tt></td><td> -- A match only occurs with text that matches the case of the search string.
</td></tr>

</td></tr>
<tr><td colspan="3">
( The empty set <tt><b>{}</b></tt> may also be specified, to search using the default options. )
</td></tr>
</table>
<p>
If a match is found, the function returns the starting and ending positions of the match,<br>
otherwise it returns <tt><b>nil</b>.</tt>
</p><p>
For example, to select the first case-sensitive whole-word match of the string
'<b>foobar</b>' you could use something like this:</p>
<pre>
a,b = geany.find( "foobar", 0, geany.length(), {"wholeword","matchcase"} )
if (a) then
geany.select(a,b)
else
geany.message("Search phrase not found.")
end

<a name="height"></a><hr><h3><tt>geany.height ()</tt></h3><p>
Returns the total number of lines in the current document.
</p><br><br>
<a name="keycmd"></a><hr><h3><tt>geany.keycmd ( command )</tt></h3><p>
Activates (runs) one of Geany's built-in menu commands.</p><p>
The <tt>command</tt> argument should be one the string constants defined in the
"<tt>glspi_keycmd.h</tt>" header from the plugin sources.
For example, to display Geany's preferences dialog, you could use:</p><p>
<tt> geany.keycmd("MENU_PREFERENCES")</tt>
</p>
<p>
This function raises an error if the command argument is invalid.
</p><br><br>
<a name="keygrab"></a><hr><h3><tt>geany.keygrab ( [prompt] )</tt></h3>
<p>Intercepts the next keyboard key pressed, preventing the editor from
receiving that keyboard event.</p>
<p>This function returns the value of the pressed key as a string.
Alphanumeric keys will return their keyboard value,
such as <tt>"a"</tt> or <tt>"1"</tt>,
while other keys may return a string describing the key,
such as <tt>"Return"</tt> or <tt>"Escape"</tt>.</p>
<p>Only one instance of this function may be active at a time.
This function will return <tt><b>nil</b></tt> if another instance is already waiting for a keypress.</p>
<p>If the optional <tt>prompt</tt> string argument is present, its text will be shown
in a "calltip" near the upper left-hand area of the current document.
The prompt will not be shown if no document is open.</p>
<p>Notes:
<ul>
<li>This function should work on non-US keyboards, although this has not been tested.
Scripts written for one keyboard may not be portable to other systems.</li>
<li>Key combinations with the modifier keys <b>[Ctrl]</b> or <b>[Alt]</b>
are not supported.</li>
<li>Detection of the <b>[Shift]</b> key state is unreliable.</li>
<li>Keys may be dropped when this function is called in rapid succession (as in a loop). For best results, use of this function should be confined to detecting single "lowercase" key presses.</li>
<li>Consult <tt>gdk/gdkkeysyms.h</tt> in the GTK sources for an idea of key names.</li>
<li>This function was primarily intended for assigning "chained" sets of hot key
options, in conjunction with user-defined <a href="geanylua-keys.html">keybindings</a>.</li>
</ul>
</p>
<br><br>
<a name="launch"></a><hr><h3><tt>geany.launch ( program [, arg1 [, arg2, ...]] )</tt></h3><p>
Executes the external application specified by <tt>program</tt>,
passing any additional arguments to its command line.
</p>
<p>
Returns <tt>true</tt> if the process was succesfully created, else it returns <tt>false</tt> plus an error message.</p>
<p>
For example:<br><tt>
local ok,msg = geany.launch("firefox", "http://www.yahoo.com/")<br>
if not ok then geany.message(msg) end</tt>
</p>
<p>
This function returns immediately, regardless of the status of the newly-created process.
If you need to wait for a process to complete before returning,
use Lua's built-in <tt>os.execute()</tt> function instead.
</p>
<p>Note that using this function on MS-Windows might require installing the
"<b><tt>gspawn-win32-helper.exe</tt></b>" program somewhere in your <tt>PATH</tt>.
( It is included in the GTK/GLib package. )</p>
<br><br>
<a name="length"></a><hr><h3><tt>geany.length ()</tt></h3><p>
Returns the text length of the current document.
</p><br><br>
<a name="lines"></a><hr><h3><tt>geany.lines ( [index] )</tt></h3><p>
When called with one argument, returns a string containing the text at
the specified line number of the current document.<br>
It may also return <tt><b>nil</b></tt> if there is no open document,
or if the specified <tt><b>index</b></tt> is outside the range of lines.
</p><p>
When called without any arguments, it returns an iterator that steps
through each line of the current document. <br>
So you can use it like this:<pre>
for line in geany.lines()
do
print(line)
end
</pre>
<br><br>
<a name="match"></a><hr><h3><tt>geany.match ( [position] )</tt></h3><p>
Attempts to find a corresponding matching brace from the given <tt><b>position</b></tt> of one brace.<br>
( If the <tt><b>position</b></tt> argument is omitted, the current caret position is assumed. )
</p>
<p>The brace characters handled are: <tt><b> () [] {} <></b></tt></p>
<p> The search is forwards from an opening brace and backwards from a closing brace.<br>
If the character at <tt><b>position</b></tt> is not a brace character, or a matching brace cannot be found,<br>
the return value is -1. Otherwise, the return value is the position of the matching brace.
</p><br><br>
<a name="navigate"></a><hr><h3><tt>geany.navigate ( mode, count [,extend [,rect]] )</tt></h3><p>
Moves the caret incrementally.</p>
<p>
The <tt><b>mode</b></tt> argument must be one of the following strings:
<ul>
<li><tt>"char"</tt> -- Move by characters.</li>
<li><tt>"part"</tt> -- Move by segments in <big>MixedCase</big> or <big>under_score</big> style identifiers.</li>
<li><tt>"word"</tt> -- Move by words.</li>
<li><tt>"edge"</tt> -- Move to beginning or end of current line.</li>
<li><tt>"line"</tt> -- Move up or down by lines.</li>
<li><tt>"para"</tt> -- Move up or down by paragraphs.</li>
<li><tt>"page"</tt> -- Move up or down by pages.</li>
<li><tt>"body"</tt> -- Move to the beginning or end of the entire document.</li>
</ul>
<p>
If the numeric <tt><b>count</b></tt> argument is <i>positive</i>, the caret is moved <i>forward</i> or <i>down</i> by that many steps.<br>
If it is <i>negative</i>, the caret is moved <i>backward</i> or <i>up</i> by that many steps.<br>
( If it is <i>zero</i> there is not much point in using this function. )<br>
There is also no point in using a magnitude greater than <i>one</i> for the <tt>"edge"</tt> or <tt>"body"</tt> modes.
</p>
<p>
If the optional boolean <tt><b>extend</b></tt> argument is <tt><b>true</b></tt>,
the selection is expanded or contracted to the new caret position,
similar to holding down the <big>[Shift]</big> key when navigating with the keyboard.
</p><p>
If the optional boolean <tt><b>rect</b></tt> argument is also <tt><b>true</b></tt>,
the selection is treated as <i>rectangular</i> rather than <i>linear</i>.<br>
( Rectangular selection is only supported for <tt>char</tt>, <tt>edge</tt>,
<tt>line</tt>, or <tt>page</tt> modes. )
</p>
<br><br>
<a name="newfile"></a><hr><h3><tt>geany.newfile ( [filename [, filetype] )</tt></h3><p>
<p>When called with no arguments, creates a new, untitled document.</p>
<p>When called with one argument, creates a new document with the specified <tt>filename</tt>.</p>
<p>When called with two argument, creates a new document with the specified
<tt>filename</tt> and <tt>filetype</tt> (a one-word description of the filetype,
e.g. "C" or "Python".). If you want untitled document then set <tt>filename</tt> as <tt>""</tt>.</p>
<p>So you can use it like this:</p>
<pre>local s = geany.selection();
if (s ~= "") and (s ~= nil) then
local t = geany.fileinfo();
geany.newfile("", t.type);
geany.selection(s);
end</pre>
<p>(create a new, untitled document, with selected text and auto set filetype).</p>
<br><br>
<a name="open"></a><hr><h3><tt>geany.open ( [filename]|[index] )</tt></h3><p>
When called with no arguments, reloads the currently active document from disk.
</p><p>
When called with a numeric argument, reloads the file of that document index.
</p><p>
When called with a string argument, it will reload that filename if it is already open,
or otherwise it will open it in a new tab. <br>
It will not create a non-existent file, for that you need to use <tt>geany.newfile()</tt>
</p>
<p>
Returns the <i>one-based</i> document index on success,
or <i>zero</i> if the document could not be opened or reloaded.</p>
<br><br>
<a name="optimize"></a><hr><h3><tt>geany.optimize ()</tt></h3><p>
Disables the Lua interpreter's "debug hook", the thing that
allows the plugin to track line number information and elapsed time.</p><p>
The advantage of calling <tt>optimize()</tt> is that a lengthy, CPU-intensive
script can sometimes run much faster.
</p><p>
The disadvantage is that you lose the line number information that helps in
debugging your script, and the built-in protection against things like endless loops.
For this reason you should only use this function if you really need it, and
only when you are reasonably sure that your script doesn't contain any errors.
</p><p>For best results this function should be called at the very
beginning of the script.
</p>
<br><br>
<a name="paste"></a><hr><h3><tt>geany.paste ()</tt></h3><p>
Pastes the text from the clipboard into the active document at the current caret position,<br>
replacing any current selection.
</p><p>
Returns <tt><b>nil</b></tt> if there is no open document,
or if the document is marked read-only.</p><p>
Otherwise it returns the effective change in the document's size. <br>
( Which may actually be negative, if the clipboard content size is less than the prior selection. )
</p>
<br><br>
<a name="reloadconf"></a><hr><h3><tt>geany.reloadconf ()</tt></h3>
<p>This function will cause Geany to reload most of it's configuration files without restarting
(as menu item <b><i>Tools-><u>R</u>eload Configuration</i></b>).</p>
<!-- The list was copied from https://geanypy.readthedocs.io/en/latest/api.html#geany.reload_configuration -->
<p>Currently the following files are reloaded:</p>
<ul>
<li>all template files;</li>
<li>new file templates;</li>
<li>the New (with template) menus will be updated;</li>
<li>Snippets (snippets.conf);</li>
<li>filetype extensions (filetype_extensions.conf);</li>
<li><i>setting</i>s and <i>build_settings</i> sections of the filetype definition files.</li>
</ul>
<p>This function which can be used if you updated one of these configuration files, or modified or added template files.</p>
<br><br>
<a name="rescan"></a><hr><h3><tt>geany.rescan ()</tt></h3><p>
Scans the scripts folder, rebuilds the <b><i>Tools-><u>L</u>ua Scripts</i></b> menu,
and re-initializes the GTK accelerator group (keybindings) associated with the plugin.
</p><br><br>
<a name="rowcol"></a><hr><h3><tt>geany.rowcol ( [position]|[line,column] )</tt></h3><p>
This function translates between line/column coordinates and linear position (offset from beginning of document).<br>
</p>
<p>The syntax takes three forms:</p>
<ul>
<li>
With <i>no</i> arguments, it returns the rectangular coordinates of the current caret position:<br>
<tt> line, column = geany.rowcol()</tt><br>
( Note that in Lua a single function call like the one above returns both values! )<br><br>
</li>
<li>
With <i>one</i> argument, it it returns the rectangular coordinates of the specified <tt><b>position</b></tt>
argument:<br>
<tt> line, column = geany.rowcol(position)</tt><br><br>
</li>
<li>
With <i>two</i> arguments, it translates from the given <tt><b>line</b></tt> and <tt><b>column</b></tt>
to the linear position:<br>
<tt> position = geany.rowcol(line,column)</tt>
</li>
</ul>
<p>
Out-of-range arguments are adjusted to the nearest valid possibility.
</p><br><br>
<a name="save"></a><hr><h3><tt>geany.save ( [filename]|[index] )</tt></h3><p>
When called with no arguments, saves the currently active document to disk.
</p><p>
When called with a numeric argument, saves the file of that document index.
</p><p>
When called with a string argument, it will save that named document ( That is, of course, if it is open. )
</p>
<p>
Returns <tt><b>true</b></tt> on success, or <tt><b>false</b></tt> if the document could not be saved.</p>
<br><br>
<a name="scintilla"></a><hr><h3><tt>geany.scintilla ( msg_id [, wparam [, lparam]] )</tt></h3><p>
<i>Power users only!</i>
</p>
<p>
Sends a <tt><b>SCI_*</b></tt> message directly to the Scintilla widget of the active document.</p>
<p>
The <tt><b>msg_id</b></tt> can be a numeric value, or a case-insensitive string with or
without the <tt>"SCI_"</tt> prefix,
such as <tt>"SCI_POSITIONFROMPOINT"</tt>, <tt>"POSITIONFROMPOINT"</tt>, or <tt>"PositionFromPoint"</tt>.
</p><p>
The wparam, lparam, and return types depend on the particular message, based on the
interface described in the "<tt><small>Scintilla.iface</small></tt>" file from the Scintilla sources.
</p><p>
For API calls which expect a pre-allocated char buffer as the lparam, the allocation is
automatically managed
by the GeanyLua module, your lparam is ignored, and the return value is a Lua string.
In cases where the length is specified
in the wparam, the null terminator is not counted - if you ask for 3 chars, you get 3 chars.
</p><p>
Currently only string, numeric, and boolean types are supported, any API call that
expects or returns complex types will result in an error. This function tries hard to
protect from garbage being passed to
Scintilla, but ultimately <i>you</i> are expected to know what you're doing!
</p><br><br>
<a name="select"></a><hr><h3><tt>geany.select ( [[start,] stop]] )</tt></h3><p>
When called with no arguments, returns the beginning <b><i>and</i></b> ending points of
the current selection, in the form:<br>
<tt>
start, stop = geany.select()
</tt><br>
( Note that in Lua a single function call like the one above returns both values! )</p>
<p>
To find out if the selection is rectangular, test the
boolean variable <tt><b>geany.rectsel</b></tt> immediately after this call.
</p>
<p><br>
If this function is called with two arguments, it creates a new selection in
the current document.
<br> The selection is <i>anchored</i> at the <tt><b>start</b></tt>
position, and <i>extended</i> to the <tt><b>stop</b></tt> position.</p><p>
The boolean variable <tt><b>geany.rectsel</b></tt> can be set prior to this
call to control
whether this selection is created in normal or rectangular mode.
</p>
<p><br>
If called with one argument, the caret is moved to that position, but no selection is created,<br>
and any existing selection is lost.
</p>
<p>
<br>
Note that in all cases, the value of <tt><b>stop</b></tt> is considered to be
the end of the selection where the caret is located.</p><p>
So, if <tt><b>stop</b></tt> is less than <tt><b>start</b></tt>, the caret is postioned
at the <i>beginning</i> of the selection, <br>similar to a selection created by
dragging the mouse <i>backwards</i> in the document.</p>
<p>
<b>Hint:</b> To select the entire document, you can use:
<tt>geany.select( 0, geany.length() )</tt>
</p><br><br>
<a name="selection"></a><hr><h3><tt>geany.selection ( [content] )</tt></h3><p>
When called with no arguments, returns the selected text in the current Geany
document as a string. <br>
Returns the empty string if no text is selected, or <tt><b>nil</b></tt>
if there is no open document.
</p><p>When called with one argument, the selected text of the current document
will be replaced with the specified <tt>content</tt>
string.<br>
If no text is currently selected, the text will be inserted at the current
(caret) position.
</p><br><br>
<a name="settype"></a><hr><h3><tt>geany.settype ( filetype )</tt></h3>
<p>Will change the current file type. Use one-word description of the
file type, e.g. "C" or "Python" (see the "<tt>filetype_extensions.conf</tt>"
file).
</p><br><br>
<a name="signal"></a><hr><h3><tt>geany.signal ( widget, signal )</tt></h3><p>
Emits a GTK signal to a given widget in the Geany user interface.</p><p>
The <tt>widget</tt> argument is a string identifying the widget by its Glade <tt><b>"id"</b></tt> attribute.<br>
The <tt>signal</tt> argument is a string identifying the signal to be emitted.
</p><p>
This function was primarily intended for activating Geany's builtin menu commands.<br>
For instance, to display the file open dialog you could do:<br>
<tt> geany.signal("menu_open1", "activate")</tt>
</p><p>
The function does not return a value, but may trigger an error message if the
widget name is not found or the signal name is not valid for the specified widget.
Note that it is generally easier and more reliable to use the <tt>keycmd()</tt> function whenever possible.
</p><br><br>
<a name="stat"></a><hr><h3><tt>geany.stat( filename [, lstat] )</tt></h3><p>
Returns a table providing some (limited) information about the specified file.<br>
If the information could not be obtained, the function returns <tt>nil</tt> plus an string describing the reason for failure.
</p>
<p>
If the file is a symbolic link, and the optional <tt>lstat</tt> argument is <tt>true</tt>, the
information is returned about the link itself, otherwise the table provides
information about the file that the link points to.
</p><p>
The returned table contains the following fields:
<table border="0" summary="stat table fields">
<tr><td width="5%"></td><td><tt>size </tt></td><td> -- The size of the file, in bytes.</td></tr>
<tr><td width="5%"></td><td><tt>time </tt></td><td> -- Modification time, in seconds from the epoch.</td></tr>
<tr><td width="5%"></td><td><tt>type </tt></td><td> -- A single-character string that denotes the type of file (see below)</td></tr>
<tr><td width="5%"></td><td><tt>read </tt></td><td> -- <tt>true</tt> if the effective user can read from the file.</td></tr>
<tr><td width="5%"></td><td><tt>write</tt></td><td> -- <tt>true</tt> if the effective user can modify the file.</td></tr>
<tr><td width="5%"></td><td><tt>exec </tt></td><td> -- <tt>true</tt> if the effective user can execute the file.</td></tr>
</table>
<p><br>
The <tt>type</tt> field contains one of the following values:
<table border="0" summary="stat table type field values">
<tr><td width="5%"></td><td><tt>"b" </tt></td><td> -- a block-oriented device.</td></tr>
<tr><td width="5%"></td><td><tt>"c" </tt></td><td> -- a character-special device.</td></tr>
<tr><td width="5%"></td><td><tt>"d" </tt></td><td> -- a directory.</td></tr>
<tr><td width="5%"></td><td><tt>"f" </tt></td><td> -- a FIFO or named pipe.</td></tr>
<tr><td width="5%"></td><td><tt>"l" </tt></td><td> -- a symbolic link.</td></tr>
<tr><td width="5%"></td><td><tt>"r" </tt></td><td> -- a regular file.</td></tr>
<tr><td width="5%"></td><td><tt>"s" </tt></td><td> -- a socket.</td></tr>
</table>
<p>
Note that this function does not support symbolic links or ACL permissions on MS-Windows.
</p><br><br>
<a name="status"></a><hr><h3><tt>geany.status ( message )</tt></h3>
<p>
Sends a message to the status tab of the messages window.
</p><p>
The <tt>message</tt> argument is the string to be displayed.
</p><p>
This function's purpose is to provide a user-friendly way to display messages without using the dialog popup.
</p><p>
This function does not return a value.</p><br><br>
<a name="text"></a><hr><h3><tt>geany.text ( [content] )</tt></h3><p>
When called with no arguments, returns the entire text of the currently
active Geany document as a string.<br>( Returns <tt><b>nil</b></tt>
if there is no open document.)
</p><p>
When called with one argument, the entire text of the current
document is replaced with the specified <tt>content</tt> string.
</p><br><br>
<a name="timeout"></a><hr><h3><tt>geany.timeout ( seconds )</tt></h3><p>
Attempts to control the maximum time allowed, in whole seconds, for the current script to
finish execution.</p><p>
By default, scripts are allowed 15 seconds to complete, but if your script needs
more time, you can increase it here.
</p><p>
Note that the interpreter is only able to trigger this "timeout exceeded" error when it is actually processing instructions.
This provides protection against things like accidentally creating an endless loop,
but it might still be possible to create a script that hangs indefinitely. ( For instance if
you call <tt>io.read()</tt> without access to a terminal. )</p><p>
The internal timer is paused whenever one of the dialog box functions is called,
to allow the user time to respond.
</p><p>
Setting the timeout to zero will disable it completely, that is, the script will never time out.
</p><p><br><br>
<a name="wkdir"></a><hr><h3><tt>geany.wkdir ( [folder] )</tt></h3><p>
When called with no arguments, returns the current working directory.</p>
<p>
When called with one argument, tries to change into that <tt>folder</tt>,
and returns <tt>true</tt> on sucess, or <tt>false</tt> plus an error message
on failure.
</p><br><br>
<a name="word"></a><hr><h3><tt>geany.word ( [position] )</tt></h3><p>
When called with no arguments, returns the word at the current caret position.
</p><p>
When called with one argument, returns the word at the specified
<tt><b>position</b></tt>.
</p><p>
This function can return an empty string if the position is not touching
a character that is considered to be part of a word. You can modify this
set of characters in the <tt><b>geany.wordchars</b></tt> variable.
</p><br><br>
<a name="xsel"></a><hr><h3><tt>geany.xsel ( [text] )</tt></h3><p>
When called with no arguments, returns the text-based contents of the primary X selection.
</p><p>
When called with one argument, assigns that <tt>text</tt> as the contents of the primary X selection.
</p><p>
This function is only valid for X-Window environments, on MS-Windows, it does nothing.
</p><br><br>
<a name="yield"></a><hr><h3><tt>geany.yield ()</tt></h3><p>
Temporarily returns control to the IDE, to allow user interface elements to
be refreshed/repainted during lengthy script operations.
</p><p>Since most scripts will probably have a run time of less than a couple of seconds,
you will likely never need this function. But if you do, it should be used with caution,
since it allows Geany's state to be changed during script execution. This could have
unpleasant consequences, for instance if the user closes a document that the script is referencing.
</p>
<br><br>
<br><br>
<hr><hr>
<!-- Dialog functions -->
<h3> Dialog functions</h3>
<hr>
<a name="choose"></a><hr><h3><tt>geany.choose ( prompt, items )</tt></h3><p>
Displays a dialog box to allow the user to choose from a list of items. </p><p>
The <tt>prompt</tt> argument string will display a message above the list box
to explain the request.</p><p>
The <tt>items</tt> argument is a Lua table, each element of the table must be
a string.
</p><p>
The function returns the selected item as a string:</p>
<ul>
<li>If the <b>OK</b> button is clicked,
<li>If the [Return] key is pressed while the item list is active.
<li>If the user double-clicks an item in the list.
</ul>
<p>
If the <b>Cancel</b> button is clicked, or if the dialog is is dismissed by
some other means, e.g. by pressing the [Escape] key, the function returns
<tt><b>nil</b></tt>.
</p><br><br>
<a name="confirm"></a><hr><h3><tt>geany.confirm ( title, question, default )</tt></h3><p>
Displays a simple yes-or-no style dialog box to ask the specified
<tt>question</tt>.<br>
The <tt>title</tt> argument is displayed as a bold-faced title for the dialog.
</p><p>
Returns <tt><b>true</b></tt> if the 'Yes' button is clicked,
or <tt><b>false</b></tt> if the 'No' button is
clicked.</p><p>
If the dialog is dismissed by some other means, e.g. by pressing the
[Escape] key, <br>the function will return the boolean value specified by the
<tt>default</tt> argument. </p>
<p>All three arguments are required, but you can pass <tt><b>nil</b></tt>
as the first argument to suppress the title.
</p><br><br>
<a name="input"></a><hr><h3><tt>geany.input ( [prompt] [,default] )</tt></h3><p>
Displays an input dialog to prompt the user for some text. </p><p>
The <tt>prompt</tt> argument string will display a message above the entry box
to explain what input is requested.</p><p>
The <tt>default</tt> argument string, if present, will add some pre-selected
text into the entry area.</p><p>
If the <b>OK</b> button is clicked, or if the [Return] key is pressed while the
entry field is active, the function will return the contents of the entry field
as a string.</p><p>
If the <b>Cancel</b> button is clicked, or if the dialog is is dismissed by
some other means, e.g. by pressing the
[Escape] key, the function returns <tt><b>nil</b></tt>.
</p><br><br>
<a name="message"></a><hr><h3><tt>geany.message ( [title,] message )</tt></h3><p>
When called with one argument, displays a simple dialog box containing
the specified <tt>message</tt> string. </p>
<p>When called with two arguments, the <tt>title</tt> argument is displayed as
a bold-faced title,
and the <tt>message</tt> argument will be the message text.
</p><br><br>
<hr>
<a name="pickfile"></a><hr><h3><tt>geany.pickfile ( [mode [,path [,filter]]] )</tt></h3>
<p>
Displays a dialog that allows the user to select a filename.</p><p>
All three arguments are optional, but you can pass <tt>nil</tt> as a placeholder to
use the default value for any of the arguments.</p><p>
The <tt>mode</tt> argument specifies the type of dialog, and must be one
of two strings, either <tt>"open"</tt> or <tt>"save"</tt>.<br>
( passing <tt>nil</tt> is the same as <tt>"open"</tt> )<br>
In <tt>"save"</tt> mode the function will issue an overwrite confirmation prompt if the targeted file already exists.
</p><p>
The <tt>path</tt> string argument sets the initial directory for the dialog, or <tt>nil</tt>
to use the current directory.<br>
If the last (rightmost) element of the path is an existing directory, the path will be used as-is,
otherwise the last element is assumed to be a filename (whether it actually exists on disk or not)
and will be parsed off and used as the suggested filename for the dialog.
</p><p>
The <tt>filter</tt> argument controls which files are displayed,
or it can be <tt>nil</tt> to display all files.<br>
It is a string consisting of pairs of substrings, where each substring
is separated by the pipe "<tt>|</tt>" symbol.<br>
The first element in each pair of substrings is the human-readable description of the filetype,<br>
and the second element of the
pair is a set of semicolon-delimited shell wildcards to filter on.<br>
For instance, a filter for web files might look like:<br>
<tt><b> "HTML files|*.html;*.htm|PHP files|*.php;*.php4|Style sheets|*.css"</b></tt>
<br>
( Those familiar with
<a href="http://en.wikipedia.org/wiki/Borland_Delphi">Borland Delphi</a>
might recognize this syntax from the
<a href="http://www.delphibasics.co.uk/RTL.asp?Name=TOpenDialog">TOpenDialog.Filter</a> property. )
</p>
<p><br>
Note that this function does not actually open or save anything, it merely returns the
full path and filename of the selected file, or <tt>nil</tt> if the user cancels the dialog.</p>
<br><br>
<hr>
<hr>
<h3>Module level variables</h3>
<hr>
<a name="wordchars"></a><hr><h3><tt>geany.wordchars</tt></h3><p>
This variable determines which characters are considered to be part of a word.
</p><p>
It is used by the <tt><b>geany.word()</b></tt> function and may also be reset by that
function if its current value cannot be interpreted as a string.</p><p>
The default value is:<br><tt>
<big> <big>
"_abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"</big> </big></tt>

If you need to modify this string, you may want to save a copy of the original
so you can restore it later.
</p><br><br>
<a name="rectsel"></a><hr><h3><tt>geany.rectsel</tt></h3><p>
This variable controls and/or returns the "selection mode" of the current document.
</p><p>
It is used by the <tt><b>geany.select()</b></tt> function and is adjusted
when the selection is queried, and examined when the selection is set. <br>
It may also be reset if its current value cannot be interpreted as a boolean.</p>
<p>
A value of <tt><b>true</b></tt> represents a rectangular selection
and <tt><b>false</b></tt> represents the normal linear selection mode.
</p><br><br>
<a name="banner"></a><hr><h3><tt>geany.banner</tt></h3><p>

</p><p>
It may be reset by the dialog functions if its value cannot be interpreted as a string.
</p><br><br>
<a name="caller"></a><hr><h3><tt>geany.caller</tt></h3><p>
This variable stores the internal index of the document that triggered one of the <a href="./geanylua-intro.html#events">event scripts</a>.</p>
<p>
For example, to print the filename of a file that has just been saved, you could put<br>
this line in your <b>~/.geany/plugins/lua/events/saved.lua</b> script file:</p><p>
<tt> print(geany.documents(geany.caller))</tt>
</p><p>
This variable is only relevant for the opened, created, activated, and saved event scripts,
for all other scripts it is set to zero.<br>
</p><br><br>
<a name="dirsep"></a><hr><h3><tt>geany.dirsep</tt></h3><p>

</p><br><br>
<a name="project"></a><hr><h3><tt>geany.project</tt></h3><p>
This variable provides a reference to the <a href="geanylua-keyfile.html">GKeyFile</a> object
for the project that triggered a
proj-* <a href="./geanylua-intro.html#events">event script</a>.</p>
<p>
The information stored in the object can be manipulated using the <tt>keyfile</tt> module.<br>
For example, to print the description of the project that has just been opened, you could put<br>
this line in your <b>~/.geany/plugins/lua/events/proj-opened.lua</b> script file:</p><p>
<tt> print(keyfile.value(geany.project, "project", "description"))</tt>
</p><p>
This variable is only relevant for the project-based event scripts, for all other scripts it is set to <tt>nil</tt>.<br>
</p><br><br>
<a name="script"></a><hr><h3><tt>geany.script</tt></h3><p>
This variable stores the full path and filename of the active script.</p>
