I maintain a vcs repository with my collection of dotfiles, which
includes tmux.conf. As I like to use a common set of dot files on most
machines I use, the config changes in the 1.6 release have left me stuck
with pre-1.6 and 1.6 config entries to achieve the desired result on all
machines, some of which use 1.6 and others which I have less control
over and have not yet been updated.
I would like to request that the tmux.conf syntax include something
similar to vim's config file evaluation, which allows conditional
inclusion of config lines based on evaluation. The has(capability) of
vim seems overkill, but being able to specify app versions (<,=,>) seems
adequate.
The effected snippets of what I had:
set -g prefix `,"C-B"
setw -g window-status-alert-fg colour228
setw -g window-status-alert-attr dim
The new content to try and cover both cases
set -g prefix `
set -g prefix2 "C-B" # tmux 1.6+ only
bind ` send-prefix
bind "C-B" send-prefix -2 # tmux 1.6+ only
# Pre tmux 1.6
setw -g window-status-alert-fg colour228
setw -g window-status-alert-attr dim
# tmux 1.6
setw -g window-status-activity-fg colour228
setw -g window-status-activity-attr dim
setw -g window-status-bell-fg colour228
setw -g window-status-bell-attr dim
setw -g window-status-content-fg colour228
setw -g window-status-content-attr dim
The problem is that know I am guaranteed to get error messages for the
statements for the incorrect version, which I would like to be able to
exclude with something like:
set -g prefix `
bind ` send-prefix
if {tmuxver} < 1.6
set -g prefix `,"C-B"
setw -g window-status-alert-fg colour228
setw -g window-status-alert-attr dim
endif
if {tmuxver} = 1.6
set -g prefix2 "C-B"
bind "C-B" send-prefix -2
setw -g window-status-activity-fg colour228
setw -g window-status-activity-attr dim
setw -g window-status-bell-fg colour228
setw -g window-status-bell-attr dim
setw -g window-status-content-fg colour228
setw -g window-status-content-attr dim
endif
