🐛 Known Issues

This is a list of issues with Fig that for one reason or another cannot be resolved upstream.

vim

Issue # Description
set ttimeoutlen=0 in vimrc results in strange output when scrolling with the mouse

Workaround: remove this line or increase the timeout value.

vim-tmux-navigator

Issue # Description
#460 Unable to navigate between panes using vim-tmux-navigator

Workaround:

I found some time to wrestle with tmux's string escaping -- here is a more concise solution that is a drop in for the is_vim variable that robustly accounts for subshells. Rather than making the bash script listed above, you can replace the is_vim function with the following directly:

is_vim="children=(); i=0; pids=( $(ps -o pid= -t '#{pane_tty}') ); \
while read -r c p; do [[ -n c && c -ne p && p -ne 0 ]] && children[p]+=\" $\{c\}\"; done <<< \"$(ps -Ao pid=,ppid=)\"; \
while (( $\{#pids[@]\} > i )); do pid=$\{pids[i++]\}; pids+=( $\{children[pid]-\} ); done; \
ps -o state=,comm= -p \"$\{pids[@]\}\" | grep -iqE '^[^TXZ ]+ +(\\S+\\/)?g?(view|n?vim?x?)(diff)?$'"

It does the same thing as the shell script above - a quick explanation line by line:

  1. Initialize a list, pids, of processes running in the current pane_tty
  2. Construct a tree, children, that maps parent to child pids
  3. Loop through descendents of pids running in pane_tty (some of which may be running in descendant ttys)
  4. Apply normal is_vim function across all descendant processes + ttys

For those using this workaround, I'm hoping this approach is more easily adaptable to future updates to the vim-tmux-navigator logic if support for nested ttys is not merged upstream here. For example, if you are encountering the freezing described in #299, this approach can be modified in a similar way as #300 to not use the -t flag of ps in line 1:

is_vim="children=(); i=0; pids=( $(ps -o pid=,tty= | grep -iE '#{s|/dev/||:pane_tty}' | awk '\{print $1\}') ); \
while read -r c p; do [[ -n c && c -ne p && p -ne 0 ]] && children[p]+=\" $\{c\}\"; done <<< \"$(ps -Ao pid=,ppid=)\"; \
while (( $\{#pids[@]\} > i )); do pid=$\{pids[i++]\}; pids+=( $\{children[pid]-\} ); done; \
ps -o state=,comm= -p \"$\{pids[@]\}\" | grep -iqE '^[^TXZ ]+ +(\\S+\\/)?g?(view|n?vim?x?)(diff)?$'"
