bash - 编写启动 ncmpcpp 的 3 个 Pane 的功能性 tmux shell 脚本是不可能的吗？

Question

这是我第二次发布问题，因为整个情况最终比我想象的更令人困惑。

我正在尝试制作一个脚本来打开 tmux，将其分成 3 个 Pane ，使它们水平大小相等，然后在所有 Pane 中启动 ncmpcpp。这是我设法编写的脚本:

#!/bin/sh

tmux new-session -d 'ncmpcpp'
printf 'creating session\n'
tmux split-window -h 'ncmpcpp'
printf 'window split 1\n'
tmux split-window -h 'ncmpcpp'
printf 'window split 2\n'
tmux select-layout even-horizontal
printf 'evening out panes\n'
tmux a #
printf 'attaching session\n'

我是编写脚本的初学者，如果这里的错误很明显，我深表歉意。 printfs 在那里，这样我就可以确定脚本在何处使 tmux 崩溃。显然，它在 tmux a # 处崩溃。

奇怪的是，崩溃是瞬间发生的。由于它消失的速度太快，我无法截图。

terminate called after throwing an instance of `std::logic_error
what() : constructed window couldn't fit into terminal'

基本上，这些 Pane 对于 ncmpcpp 来说太小了，无法在其中启动。尽管我可以在更小的终端中手动启动 ncmpcpp。

然而，经过一番折腾，我不小心“有点”解决了问题。

我把脚本搞砸了，结果是这样的:

#!/bin/sh

printf '\033[8;29;252t'
tmux new-session -d 

tmux select-layout even-horizontal
tmux send-keys -t 0 'tput cols' Enter
tmux split-window -h 

sleep 1

tmux select-layout even-horizontal
tmux send-keys -t 1 'tput cols' Enter
tmux split-window -h 

sleep 1

tmux select-layout even-horizontal
tmux send-keys -t 2 'tput cols' Enter

sleep 1

tmux send-keys -t 0 'ncmpcpp' Enter
tmux send-keys -t 1 'ncmpcpp' Enter
tmux send-keys -t 2 'ncmpcpp' Enter
tmux a #

开始时暂停 3 秒，然后立即启动 tmux，有 3 个面板，所有面板上都有 ncmpcpp。

...有时。

它并非一直有效，有时某些 Pane 会彻底崩溃，有时则不会。

老实说，我对这里发生的事情感到很困惑。我的猜测是 Pane 的大小没有记录好，足以搞砸每个 Pane 有多少列/行的值。但老实说，我很难过。

这就是我问这个问题的原因 - ncmpcpp 仅在终端尺寸足够大时启动。由于 tmux 混淆了说明列是什么的实际值，是否不可能执行我在标题中所说的内容？

所以

#!/bin/sh

printf '\033[8;29;252t'
tmux new-session -d -x 252 -y 29

tmux select-layout even-horizontal
tmux send-keys -t 0 'tput cols' Enter
tmux split-window -h 

sleep 1

tmux select-layout even-horizontal
tmux send-keys -t 1 'tput cols' Enter
tmux split-window -h 

sleep 1

tmux select-layout even-horizontal
tmux send-keys -t 2 'tput cols' Enter

sleep 1

tmux send-keys -t 0 'ncmpcpp -s playlist' Enter
tmux send-keys -t 1 'ncmpcpp -s media_library' Enter
tmux send-keys -t 2 'ncmpcpp -s clock' Enter

# help,playlist,browser,search_engine,media_library,
# playlist_editor,tag_editor,outputs,visualizer,clock

tmux a #

是你自己的答案。您是否尝试过更改 ncmpcpp 布局: (用-c调用)

ncmpcpp -c ~/.my_ncmpcpp.conf

或者这可能是您想要的东西。
