get_version

Description#

If tmux is built from git master, the version returned will be the latest version appended with -master, e.g. 2.4-master.

If using OpenBSD's base system tmux, the version will have -openbsd appended to the latest version, e.g. 2.4-openbsd.

Notes

Memoized via functools.cache , keyed on the tmux_bin argument (None is a distinct key from any explicit path), independently of get_version_str . The cache is sticky across PATH changes and on-disk binary swaps when tmux_bin is None or the same path string -- call get_version.cache_clear() to invalidate. Tests that monkey-patch tmux_cmd should call cache_clear() before asserting parsed-version behavior.
