get_block_indent(tss, style_key) -> indent

Get block indentation from TSS for a style key

get_list_indent_per_level(tss) -> indent

Get indent columns per list nesting level from TSS

expand_tabs(line, tabstop) -> expanded

Expand tab characters to spaces

clamp_display_width(text, width) -> clamped

Clamp text to a maximum display width

clamp_display_width_measured(text, width) -> clamped, visual_width

Clamp text to a maximum display width, returning both clamped text and its visual width

take_prefix_by_display(text, max_width) -> prefix, char_count, display_width

Get a UTF-8 prefix that fits within a display width

wrap_content(content, width) -> lines

Wrap content with inline ranges to fit a display width

Word-wraps content.plain at width display columns, splitting content.ranges across the resulting lines. Returns an array of content tables {plain, ranges} — one per wrapped line — with range positions adjusted to each line's local coordinate system. Returns the original content in a single-element array when no wrapping is needed.

inline_elements_for_tag(tag, attrs) -> elements

Map an inline tag (with optional attrs) to TSS element names

normalize_table_cell_content(content) -> normalized

Normalize table cell content to {plain, ranges} form

render_thematic_break(tss, width) -> rendered

Render a thematic break and return the styled string with trailing newlines

compute_list_marker(tss, depth, list, item_count, task_info) -> marker_text, marker_width

Compute list marker text, width, and continuation indent

Computes the rendered list marker for a list item. list must have ordered (bool) and start (number) fields. task_info, when non-nil, must have a checked field. Returns the styled marker text (including base indent) and its display width.

clip_content_with_ranges(content, max_width) -> clipped, width

Clip content with inline ranges to a maximum display width

build_table_border_chars(tss) -> b

Build the 14-character table border map from TSS

build_table_border_line(styled_border, b, col_widths, line_type) -> line

Build a styled table border line (top, separator, or bottom)

line_type is one of "top", "separator", or "bottom". styled_border is a function that applies table.border styling to a string. b is the border char map from build_table_border_chars.

build_wrapped_cell_line_content(content, parts) -> line_content, line_width

Build wrapped cell line content with range remapping

Given the original cell content (with .plain and .ranges) and parts from table_layout.wrap_text_with_spans, builds a new content table for one wrapped line with ranges remapped to local coordinates. Returns {plain, ranges} and the display width.

render_bordered_block(tss, style_base, lines, width, label, indent, pad) -> rendered

Render a bordered block (code blocks) returning styled string

render_bordered_content(tss, style_base, content, width, label, indent, pad) -> rendered

Render pre-styled content with borders (for divs)

Unlike render_bordered_block, this takes already-rendered content with ANSI codes and wraps it in border characters.

compute_div_layout(tss, class, current_width) -> layout

Compute div layout parameters from TSS

Returns {style_base, el_width, pad, align} for a fenced div.

render_blockquote_lines(tss, content) -> lines

Render blockquote lines with bar prefix

Returns an array of bar-prefixed lines from captured blockquote content.
