ECMA-48 defines rendition mode 2 as: faint, decreased intensity or second colour Faint mode shares its inverse (22) with bold (1): normal colour or normal intensity (neither bold nor faint) The Renditions::attribute_type enum already included 'faint' but the value remained unused until now.

ECMA-48 defines rendition mode 9 as: crossed-out (characters still legible but marked as to be deleted), and mode 29 as the inverse: not crossed out Modern terminals (including xterm, tmux, libvte, etc.) support rendering strikethrough. Further, ncurses since version 6.1 includes the smxx/rmxx user-defined terminal capabilities in the tmux and xterm-basic databases. Note that the new attribute still fits in the eight bits allocated for Renditions::attributes, so there is no need to increase the size of Cell. Signed-off-by: Stanislav Spassov <[email protected]>

What needs to be added or changed before this can be merged? It's a trivial change, it works, and it's a feature I'd really like to have. I'm currently patching mosh on several machines by hand, because a program uses faint text, which mosh does not yet support. It would support it with this PR. I've checked the resources, and the ANSI escape sequences used in these commits are correct, including the dual functionality of 22 which unsets both dim and bold. Please consider merging this PR. If any further work is needed, I might be willing to do it. But from the looks of it, it looks very correct and complete. |
