Module flags 

Bit positions inside Cell::flags. Use the named constants; raw bit math here would be a future maintenance hazard.

Constants

BOLD

S3.a (2026-05-26): text-attribute modifier — bold glyph. Set by the cell-builder from host::Theme::syntax_style(style).modifiers.bold so the renderer paints the cell with its font’s bold weight.

DIM

Text-attribute modifier — dimmed cell. From host::Theme::syntax_style(style).modifiers.dim. The renderer typically blends fg toward the pane background.

INLAY

Cell came from an inlay-hint splice rather than source text. The body codepoint is still the inlay’s character; this bit only marks provenance so byte↔column remap can distinguish inlay positions from source bytes.

ITALIC

Text-attribute modifier — italic glyph. From host::Theme::syntax_style(style).modifiers.italic.

REVERSE

Text-attribute modifier — reverse video (swap fg/bg). From host::Theme::syntax_style(style).modifiers.reverse.

UNDERLINE

Text-attribute modifier — underlined glyph. From host::Theme::syntax_style(style).modifiers.underline. The renderer is responsible for the underline geometry (font baseline + 1px, etc.).

WS_MARKER

Whitespace-marker cell (e.g. tab indicator →, EOL ·). Source text at this position was whitespace; the renderer substituted a marker glyph. Used by listchars-style rendering.

WS_TRAILING

B2.2 (2026-06-04): trailing-whitespace marker. Set in addition to WS_MARKER when the marker glyph stands in for whitespace after the last non-blank char on the line (or on an all-blank line). Lets a consumer resolve the trailing-whitespace foreground (theme.whitespace_trailing_style) from the run/cell alone — the DisplayLine model carries no byte positions, so without this bit a DisplayLine → CellMatrix projection could not reproduce the cell path’s trailing-red.
