Juraj Lutter 3cf65f8a7f sh(1): Allow non-printing characters in prompt strings ... Introduce new prompt format characters: - '\[' starts the sequence of non-printing chatacters - '\]' ends the sequence of non-printing characters Within these sequences, the following characters are now supported: - '\a' emits ASCII BEL (0x07, 007) character - '\e' emits ASCII ESC (0x1b, 033) character - '\r' emits ASCII CR (0x0d, 015) character - '\n' emits ASCII CRLF sequence These can be used to embed ANSI sequences into prompt strings. Example in .shrc: PS1="\[\e[7m\]\u@\h\[\e[0m\]:\w \\$ " This tries to maintain some degree of compatibility with GNU bash, that uses GNU readline library (which behaves slightly different from BSD editline): It has two "non-printing boundary" characters: - RL_PROMPT_START_IGNORE (\001) - RL_PROMPT_END_IGNORE (\002) while BSD editline only has one (when using EL_PROMPT_ESC setting), so for this purpose, ASCII \001 was chosen and both \[ and \] emits this character. And while here, enlarge PROMPTLEN from 128 to 192 characters. Reviewed by: jilles Approved by: jilles Differential Revision: https://reviews.freebsd.org/D37701		2022-12-22 19:10:48 +01:00
