Overview ¶
Package display is the one canonical sanitizer for anything a hostile or careless bus payload (subject, body, reply preview) could put in front of an operator's terminal: the renderer, journal preview columns, and the station TUI all funnel through Sanitize rather than each rolling their own escaping. It has no dependency on internal/humancli or internal/daemon so the daemon can sanitize at journal time without importing the CLI.

Functions ¶
func Sanitize ¶
Sanitize strips control characters that could corrupt a terminal or a TUI pane — C0/C1 controls, NUL, full ESC/CSI escape sequences, and Unicode bidi override characters (U+202A-202E, U+2066-2069) — collapses runs of tab/newline/CR into a single space, and truncates the result to maxWidth display columns (wide/combining runes counted properly, not rune count), appending '…' when truncation actually cuts content. maxWidth <= 0 yields "" (there is no room even for the ellipsis). This is the one-line contract: every caller that renders a single terminal row (journal preview columns, the station TUI's list/status rows) funnels through this. A caller that needs to keep a multi-line body's paragraph/list structure — the station conversation view's message bodies — wants SanitizeLines instead, which shares this function's exact character-level cleaning via cleanControls but preserves newlines rather than collapsing them to spaces.
func SanitizeLines ¶
SanitizeLines cleans a multi-line body with the SAME character-level scrubbing Sanitize uses — C0/C1 controls, NUL, full ESC/CSI escape sequences, 8-bit and UTF-8-encoded C1 introducers, and Unicode bidi override characters — but, unlike Sanitize, preserves newlines (and blank lines) instead of collapsing them to a single space, then splits the result into lines. Intra-line runs of tab/CR still collapse to a single space exactly as Sanitize's do; only '\n' survives as a literal line break. No width cap: callers (the station conversation body path) wrap each returned line to their pane's width themselves, since word-wrapping a multi-line body needs per-line control the single maxWidth-and-truncate contract above doesn't offer.
