MarkdownGtk.Render – ollmchat – Vala Binding Reference

Description:

public class Render : RenderBase

Renders markdown content to a Gtk.TextBuffer using a state-based renderer.

Processes markdown blocks and spans, converting them to Pango markup and inserting them into the specified TextBuffer range.

## Entry Points

The Render class provides three public methods for processing content:

- add: Adds text to be parsed and rendered incrementally. Use this for streaming content where you receive chunks over time.

- add_start: Starts a new chunk of content. This resets the parser's internal state and should be called when beginning a new content block. You should call flush before calling this if you've been adding content with add.

- flush: Finalizes the current chunk. Call this before starting a new chunk with add_start to ensure all pending content is processed.

HTML tags embedded in the markdown content are automatically parsed and handled. The parser recognizes HTML tags and creates states for them. You only need to provide opening HTML tags in your content. The renderer automatically handles closing tags when the corresponding state is closed or when flush is called.

Package: ollmchat

Properties:

public Box? box { get; }

public TextBuffer? current_buffer { get; }

public State? current_state { get; }

public TextView? current_textview { get; }

public State? default_state { get; set; }

public bool scroll_to_end { get; set; }

public TopState? top_state { get; }

Creation methods:

public Render (Box box)

Creates a renderer that appends content to the given box.

Methods:

public override void add (string text)

Override add() to check that TextView is created (programming error if not).

public void clear ()

Clears all state, including sourceviews.

public void end_block ()

Ends the current block.

public override void on_a (bool is_start, string href, string title, bool is_reference)

Callback for link spans. Renders link text with shared style and stores href/title on a per-link tag.

public override void on_br ()

Callback for line breaks (hard breaks).

public override void on_code (bool is_start, string lang, char fence_char)

Callback for code blocks.

public override void on_code_block (bool is_start, string lang)

public override void on_code_span (bool is_start)

Callback for inline code spans.

public override void on_code_text (string text)

public override void on_del (bool is_start)

Callback for strikethrough spans.

public override void on_em (bool is_start)

Callback for emphasis/italic spans.

public override void on_entity (string text)

Callback for HTML entities. The entity is already decoded, so just add as text.

public override void on_h (bool is_start, uint level)

Callback for header blocks.

public override void on_hr ()

Callback for horizontal rule blocks.

public override void on_html (bool is_start, string tag, string attributes)

Callback for HTML tags. Parser sends the tag name and attributes, we create a new state, and parser will call on_html(false, ...) for the close tag.

public override void on_img (string src, string title)

Callback for image spans.

public override void on_li (bool is_start, int list_number = 0, uint space_skip = 0, int task_checked = -1)

public override void on_list (bool is_start)

public override void on_other (bool is_start, string tag_name)

Generic callback for unmapped block/span types.

public override void on_p (bool is_start)

Callback for paragraph blocks.

public override void on_quote (bool is_start, uint level)

Callback for blockquote blocks.

public override void on_softbr ()

Callback for soft line breaks. Inserts a space (or newline in code blocks).

public override void on_strong (bool is_start)

Callback for strong/bold spans.

public override void on_table (bool is_start)

public override void on_table_cell (bool is_start, int align)

public override void on_table_hcell (bool is_start, int align)

public override void on_table_row (bool is_start)

public override void on_task_list (bool is_start, bool is_checked)

public override void on_text (string text)

Callback for normal text content.

public override void on_u (bool is_start)

Callback for underline spans.

public void start ()

Starts/initializes the renderer for a new block.

Signals:

public signal void code_block_content_updated ()

public signal void code_block_ended (string content, string language)

public signal void link_clicked (string href, string title)

Emitted when the user activates a link. Connect to open URL or handle app-specific navigation.
