前置き: 簡単なshell-scriptを設置してみる。
Read previous articles, if needed.
1. Call shell from yazi & variables(変数).
- Read following page to call & run shell command.
1-2. Outline.
- Find "shell" secsion like below.
Run a shell command.
Argument/Option Description
[template] Optional, command template to be run.
--block: Open in a blocking manner. After setting this, Yazi will hide into a secondary screen and display the program on the main screen until it exits. During this time, it can receive I/O signals, which is useful for interactive programs.
--orphan: Keep the process running even if Yazi has exited, once specified, the process will be detached from the task scheduling system.
--interactive: Request the user to input the command to be run interactively
--cursor: Set the initial position of the cursor in the interactive command input box.
For example, shell 'zip -r .zip "$0"' --cursor=7 --interactive places the cursor before .zip.
- Some Variables.
You can use the following shell variables in [run]:
$n (Unix) / %n (Windows): The N-th selected file, starting from 1. e.g. $2 represents the second selected file.
$@ (Unix) / %* (Windows): All selected files, i.e. $1, $2, ..., $n.
$0 (Unix) / %0 (Windows): The hovered file.
- ささやかな補足。（上の英語がわかる人は不要。）
次の章を読めば、わかりますが、例えば、以下のように使います。
'shell "command $0" --block'
- optionに注意。
--block # file managerの画面が切り替わり、terminalの画面に。exitでfile managerに戻ります。
--interactive # file manager 上で floatの sehllが現れ、そこに直接入力するようです。
BGで動くのか？ 動作は未確認。
以下の画面が --ineractive？
1-2. Variables
$n (Unix) : The N-th selected file, starting from 1. e.g. $2 represents the second selected file.
$@ (Unix) : All selected files, i.e. $1, $2, ..., $n.
## 以下がわかりにくいが、カーソルがあるfile？
$0 (Unix) : The hovered file.
white area: $0 カーソル下の白い部分のfileが $0 のようだ。
head yelow : $@ 黄色になっている部分が $@ ?
以下に興味深い記事がある。
Next Tab macros
以下のような変数が今も使えるのか、どうか不明？
Yazi has a set of equivalents like $0 for %c , $PWD for *%d, $@ and "$*" for %p. For %f and %s, you can get them using basename, like $(basename "$0"). I'm not sure what %t means in the context of "tagged files"
上の引用から推測。
間違っていたら、ごめんなさいね。
Sorry, if I missunderstand about blow vriables.
$PWD : current directory.
$(basename "$0") : the highlighted file basename
$(basename "$0") : the selected files basename in the current directory
%0 : the full paths of the currently copied/cut files
%@ : the full paths of selected files
2. Some examples of my script.
use prefix "x"
2-1. Display file using "less" or "bat".
Sometimes, I use less, lv to read a file.
Rust's bat has a nice way to display a file.
Display file under the cursor: $0 (white)
[[manager.prepend_keymap]]
on = [ "x", "i" ]
run = 'shell "/usr/bin/less $0" --block'
desc = show file, less "
[[manager.prepend_keymap]]
on = [ "x", "I" ]
run = 'shell "/usr/bin/bat $0" --block'
desc = "show file, bat "
2-2. Backup, copy etc a file or directory under the cursor.
Copy etc file or directory under the cursor: $0 (white)
You had better create a shell-script and place it in your PATH.
I place mine under "$HOME/bin/" .
[[manager.prepend_keymap]]
on = [ "x", "b" ]
run = 'shell "$HOME/bin/backup-file.sh $0" '
desc = "backup file"
2-3. Show "diff" between files, or open multiple files, using vim.
Select files using yazi's visual mode before run.: $@ (yellow)
## vim -d
[[manager.prepend_keymap]]
on = [ "x", "d" ]
run = 'shell "/usr/bin/vim -d $@" --block'
desc = "vim -d files"
## vim -o
[[manager.prepend_keymap]]
on = [ "x", "o" ]
run = 'shell "/usr/bin/vim -O $@" --block'
desc = "vim -O files"
