Functions

func CompletionErrorQuark 

func CompletionErrorQuark() glib.Quark

The function returns the following values:

func FileLoaderErrorQuark 

func FileLoaderErrorQuark() glib.Quark

The function returns the following values:

func FileSaverErrorQuark 

func FileSaverErrorQuark() glib.Quark

The function returns the following values:

func UtilsEscapeSearchText 

func UtilsEscapeSearchText(text string) string

UtilsEscapeSearchText: use this function to escape the following characters: \n, \r, \t and \.

For a regular expression search, use g_regex_escape_string() instead.

One possible use case is to take the TextBuffer's selection and put it in a search entry. The selection can contain tabulations, newlines, etc. So it's better to escape those special characters to better fit in the search entry.

See also: gtk_source_utils_unescape_search_text().

<warning> Warning: the escape and unescape functions are not reciprocal! For example, escape (unescape (\)) = \\. So avoid cycles such as: search entry -> unescape -> search settings -> escape -> search entry. The original search entry text may be modified. </warning>.

The function takes the following parameters:

  • text to escape.

The function returns the following values:

  • utf8: escaped text.

func UtilsUnescapeSearchText 

func UtilsUnescapeSearchText(text string) string

UtilsUnescapeSearchText: use this function before gtk_source_search_settings_set_search_text(), to unescape the following sequences of characters: \n, \r, \t and \\. The purpose is to easily write those characters in a search entry.

Note that unescaping the search text is not needed for regular expression searches.

See also: gtk_source_utils_escape_search_text().

The function takes the following parameters:

  • text to unescape.

The function returns the following values:

  • utf8: unescaped text.

The function returns the following values:

  • ok: whether iter was moved.

func (*Buffer) BeginNotUndoableAction 

func (buffer *Buffer) BeginNotUndoableAction()

BeginNotUndoableAction marks the beginning of a not undoable action on the buffer, disabling the undo manager. Typically you would call this function before initially setting the contents of the buffer (e.g. when loading a file in a text editor).

func (*Buffer) CreateSourceMark 

func (buffer *Buffer) CreateSourceMark(name, category string, where *gtk.TextIter) *Mark

CreateSourceMark creates a source mark in the buffer of category category. A source mark is a TextMark but organised into categories. Depending on the category a pixbuf can be specified that will be displayed along the line of the mark.

Like a TextMark, a SourceMark can be anonymous if the passed name is NULL. Also, the buffer owns the marks so you shouldn't unreference it.

Marks always have left gravity and are moved to the beginning of the line when the user deletes the line they were in.

Typical uses for a source mark are bookmarks, breakpoints, current executing instruction indication in a source file, etc..

The function takes the following parameters:

  • name (optional) of the mark, or NULL.
  • category: string defining the mark category.
  • where: location to place the mark.

The function returns the following values:

  • mark: new SourceMark, owned by the buffer.

func (*Buffer) EndNotUndoableAction 

func (buffer *Buffer) EndNotUndoableAction()

EndNotUndoableAction marks the end of a not undoable action on the buffer. When the last not undoable block is closed through the call to this function, the list of undo actions is cleared and the undo manager is re-enabled.

func (*Buffer) EnsureHighlight 

func (buffer *Buffer) EnsureHighlight(start, end *gtk.TextIter)

EnsureHighlight forces buffer to analyze and highlight the given area synchronously.

<note> <para> This is a potentially slow operation and should be used only when you need to make sure that some text not currently visible is highlighted, for instance before printing. </para> </note>.

The function takes the following parameters:

  • start of the area to highlight.
  • end of the area to highlight.

func (*Buffer) ForwardIterToSourceMark 

func (buffer *Buffer) ForwardIterToSourceMark(iter *gtk.TextIter, category string) bool

The function takes the following parameters:

  • highlight: TRUE if you want matching brackets highlighted.

func (*Buffer) SetHighlightSyntax 

func (buffer *Buffer) SetHighlightSyntax(highlight bool)

SetHighlightSyntax controls whether syntax is highlighted in the buffer.

If highlight is TRUE, the text will be highlighted according to the syntax patterns specified in the SourceLanguage set with gtk_source_buffer_set_language().

If highlight is FALSE, syntax highlighting is disabled and all the TextTag objects that have been added by the syntax highlighting engine are removed from the buffer.

The function takes the following parameters:

  • highlight: TRUE to enable syntax highlighting, FALSE to disable it.

func (*Buffer) SetImplicitTrailingNewline 

func (buffer *Buffer) SetImplicitTrailingNewline(implicitTrailingNewline bool)

SetImplicitTrailingNewline sets whether the buffer has an implicit trailing newline.

If an explicit trailing newline is present in a TextBuffer, TextView shows it as an empty line. This is generally not what the user expects.

If implicit_trailing_newline is TRUE (the default value): - when a SourceFileLoader loads the content of a file into the buffer, the trailing newline (if present in the file) is not inserted into the buffer. - when a SourceFileSaver saves the content of the buffer into a file, a trailing newline is added to the file.

On the other hand, if implicit_trailing_newline is FALSE, the file's content is not modified when loaded into the buffer, and the buffer's content is not modified when saved into a file.

The function takes the following parameters:

  • implicitTrailingNewline: new value.

func (*Buffer) SetLanguage 

func (buffer *Buffer) SetLanguage(language *Language)

SetLanguage associates a SourceLanguage with the buffer.

Note that a SourceLanguage affects not only the syntax highlighting, but also the [context classes][context-classes]. If you want to disable just the syntax highlighting, see gtk_source_buffer_set_highlight_syntax().

The buffer holds a reference to language.

The function takes the following parameters:

  • language (optional) to set, or NULL.

func (*Buffer) SetMaxUndoLevels 

func (buffer *Buffer) SetMaxUndoLevels(maxUndoLevels int)

SetMaxUndoLevels sets the number of undo levels for user actions the buffer will track. If the number of user actions exceeds the limit set by this function, older actions will be discarded.

If max_undo_levels is -1, the undo/redo is unlimited.

If max_undo_levels is 0, the undo/redo is disabled.

The function takes the following parameters:

  • maxUndoLevels: desired maximum number of undo levels.

func (*Buffer) SetStyleScheme 

func (buffer *Buffer) SetStyleScheme(scheme *StyleScheme)

SetStyleScheme sets a SourceStyleScheme to be used by the buffer and the view.

Note that a SourceStyleScheme affects not only the syntax highlighting, but also other SourceView features such as highlighting the current line, matching brackets, the line numbers, etc.

Instead of setting a NULL scheme, it is better to disable syntax highlighting with gtk_source_buffer_set_highlight_syntax(), and setting the SourceStyleScheme with the "classic" or "tango" ID, because those two style schemes follow more closely the GTK+ theme (for example for the background color).

The buffer holds a reference to scheme.

The function takes the following parameters:

  • scheme (optional) or NULL.

func (*Buffer) SetUndoManager 

func (buffer *Buffer) SetUndoManager(manager UndoManagerer)

func (search *SearchContext) Forward(iter *gtk.TextIter) (matchStart, matchEnd *gtk.TextIter, ok bool)

Forward synchronous forward search. It is recommended to use the asynchronous functions instead, to not block the user interface. However, if you are sure that the buffer is small, this function is more convenient to use.

Deprecated: Use gtk_source_search_context_forward2() instead.

The function takes the following parameters:

  • iter: start of search.

The function returns the following values:

  • matchStart (optional): return location for start of match, or NULL.
  • matchEnd (optional): return location for end of match, or NULL.

An example will be clearer: if the SourceView:indent-width is 4 and SourceView:tab-width is 8 and SourceView:insert-spaces-instead-of-tabs is FALSE, then pressing the tab key at the beginning of a line will insert 4 spaces. So far so good. Pressing the tab key a second time will remove the 4 spaces and insert a \t character instead (since SourceView:tab-width is 8). On the other hand, if SourceView:insert-spaces-instead-of-tabs is TRUE, the second tab key pressed will insert 4 more spaces for a total of 8 spaces in the TextBuffer.

The test-widget program (available in the GtkSourceView repository) may be useful to better understand the indentation settings (enable the space drawing!).
