Description
|
|
-----------
|
|
|
|
Base class for syntax highlighters. Provides syntax highlighting data to a :ref:`TextEdit<class_TextEdit>`. The associated :ref:`TextEdit<class_TextEdit>` will call into the **SyntaxHighlighter** on an as-needed basis.
|
|
|
|
\ **Note:** A **SyntaxHighlighter** instance should not be used across multiple :ref:`TextEdit<class_TextEdit>` nodes.

|void| **clear_highlighting_cache**\ (\ ) :ref:`🔗<class_SyntaxHighlighter_method_clear_highlighting_cache>`
|
|
|
|
Clears all cached syntax highlighting data.
|
|
|
|
Then calls overridable method :ref:`_clear_highlighting_cache()<class_SyntaxHighlighter_private_method__clear_highlighting_cache>`.

:ref:`Dictionary<class_Dictionary>` **get_line_syntax_highlighting**\ (\ line\: :ref:`int<class_int>`\ ) :ref:`🔗<class_SyntaxHighlighter_method_get_line_syntax_highlighting>`
|
|
|
|
Returns the syntax highlighting data for the line at index ``line``. If the line is not cached, calls :ref:`_get_line_syntax_highlighting()<class_SyntaxHighlighter_private_method__get_line_syntax_highlighting>` first to calculate the data.
|
|
|
|
Each entry is a column number containing a nested :ref:`Dictionary<class_Dictionary>`. The column number denotes the start of a region, the region will end if another region is found, or at the end of the line. The nested :ref:`Dictionary<class_Dictionary>` contains the data for that region. Currently only the key ``"color"`` is supported.
|
|
|
|
\ **Example:** Possible return value. This means columns ``0`` to ``4`` should be red, and columns ``5`` to the end of the line should be green:
|
|
|
|
::
|
|
|
|
{
|
|
0: {
|
|
"color": Color(1, 0, 0)
|
|
},
|
|
5: {
|
|
"color": Color(0, 1, 0)
|
|
}
|
|
}

:ref:`TextEdit<class_TextEdit>` **get_text_edit**\ (\ ) |const| :ref:`🔗<class_SyntaxHighlighter_method_get_text_edit>`

|void| **update_cache**\ (\ ) :ref:`🔗<class_SyntaxHighlighter_method_update_cache>`

Clears then updates the **SyntaxHighlighter** caches. Override :ref:`_update_cache()<class_SyntaxHighlighter_private_method__update_cache>` for a callback.
|
|
|
|
\ **Note:** This is called automatically when the associated :ref:`TextEdit<class_TextEdit>` node, updates its own cache.
