gtksourceview.SourceBuffer.set_check_brackets

    def set_check_brackets(check_brackets)

The set_check_brackets() method controls the bracket match highlighting function in the buffer. If activated, when you position your cursor over a bracket character (a parenthesis, a square bracket, etc.) the matching opening or closing bracket character will be highlighted. You can specify the style with the set_bracket_match_style function.

gtksourceview.SourceBuffer.get_check_brackets

    def get_check_brackets()

The get_check_brackets() method returns the value of the "check-brackets" property which determines if the matching brackets highlight is active.

gtksourceview.SourceBuffer.set_bracket_match_style

    def set_bracket_match_style(style)

The set_bracket_match_style() method sets the style used for highlighting matching brackets.

gtksourceview.SourceBuffer.set_highlight

    def set_highlight(highlight)

The set_highlight() method controls whether text is highlighted in the buffer. If highlight is TRUE , the text will be highlighted according to the patterns installed in the buffer (either set with set_language or by adding individual gtksourceview.SourceTag tags to the buffer's tag table). Otherwise, any current highlighted text will be restored to the default buffer style.

Tags not of gtksourceview.SourceTag type will not be removed by this option, and normal GtkTextTag priority settings apply when highlighting is enabled.

If not using a gtksourceview.SourceLanguage for setting the highlighting patterns in the buffer, it is recommended for performance reasons that you add all the gtksourceview.SourceTag tags with highlighting disabled and enable it when finished.

gtksourceview.SourceBuffer.get_highlight

    def get_highlight()

The get_highlight() method returns the value of the "highlight" property which determines if the text highlighting is active.

gtksourceview.SourceBuffer.set_max_undo_levels

    def set_max_undo_levels(max_undo_levels)

The set_max_undo_levels() method 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.

A new action is started whenever the function begin_user_action is called. In general, this happens whenever the user presses any key which modifies the buffer, but the undo manager will try to merge similar consecutive actions, such as multiple character insertions into one action. But, inserting a newline does start a new action.

gtksourceview.SourceBuffer.get_max_undo_levels

    def get_max_undo_levels()

The get_max_undo_levels() method returns the value of the "max-undo-levels" property which determines the number of undo levels the buffer will track for buffer edits.

gtksourceview.SourceBuffer.set_language

    def set_language(language)

The set_check_brackets() method Sets the gtksourceview.SourceLanguage the source buffer will use, adding gtksourceview.SourceTag tags with the language's patterns and setting the escape character with set_escape_char. Note that this will remove any gtksourceview.SourceTag tags currently in the buffer's tag table. The buffer holds a reference to the language set.

gtksourceview.SourceBuffer.get_language

    def get_language()

The get_check_brackets() method determines the gtksourceview.SourceLanguage used by the buffer. The returned object should not be unreferenced by the user.

gtksourceview.SourceBuffer.set_escape_char

    def set_escape_char(escape_char)

The set_check_brackets() method sets the escape character to be used by the highlighting engine.

When performing the initial analysis, the engine will discard a matching syntax pattern if it's prefixed with an odd number of escape characters. This allows for example to correctly highlight strings with escaped quotes embedded.

This setting affects only syntax patterns (i.e. those defined in gtksourceview.SourceTag tags).

gtksourceview.SourceBuffer.get_escape_char

    def get_escape_char()

The get_escape_char() method determines the escaping character used by the source buffer highlighting engine.

gtksourceview.SourceBuffer.can_undo

    def can_undo()

The can_undo() method determines whether a source buffer can undo the last action.

gtksourceview.SourceBuffer.can_redo

    def can_redo()

The can_redo() method Determines whether a source buffer can redo the last action (i.e. if the last operation was an undo).

gtksourceview.SourceBuffer.undo

    def undo()

The undo() Undoes the last user action which modified the buffer. Use can_undo to check whether a call to this function will have any effect.

Actions are defined as groups of operations between a call to begin_user_action() and end_user_action(), or sequences of similar edits (inserts or deletes) on the same line.

gtksourceview.SourceBuffer.redo

    def redo()

The redo() method redoes the last undo operation. Use can_redo to check whether a call to this function will have any effect.

gtksourceview.SourceBuffer.begin_not_undoable_action

    def begin_not_undoable_action()

The begin_not_undoable_action() 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).

You may nest begin_not_undoable_action() / end_not_undoable_action() blocks.

gtksourceview.SourceBuffer.end_not_undoable_action

    def end_not_undoable_action()

The end_not_undoable_action() method 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.

gtksourceview.SourceBuffer.gtk_source_buffer_new_with_language

    def gtksourceview.SourceBuffer.gtk_source_buffer_new_with_language(language)

Creates a new source buffer using the highlighting patterns in language. This is equivalent to creating a new source buffer with the default tag table and then calling set_language
