Allows using the fancy-ctrl-z functionality of toggling between the last two suspended jobs (`%+` and `%-`, respectively) even if there are more than two jobs suspended. Made the whole implementation more robust, especially in case Ctrl-Z is pressed with an existing non-empty prompt buffer. Fixed a bug where jobs with multiple different working directories would cause the back-and-forth functionality to not work.

# fancy-ctrl-z
|
|
|
|
Allows pressing <kbd>Ctrl</kbd>-<kbd>Z</kbd> is an empty prompt to bring to the
|
|
foreground the only suspended job, or, if there are more than one such jobs, to
|
|
switch between the two most recently suspended ones.
|
|
|
|
To use it, add `fancy-ctrl-z` to the `plugins` array in your `.zshrc` file:
|
|
|
|
```zsh
|
|
plugins=(... fancy-ctrl-z)
|
|
```
|
|
|
|
## Motivation
|
|
|
|
I frequently need to execute random commands in my shell.
|
|
To achieve it, I often pause Vim by pressing <kbd>Ctrl</kbd>-<kbd>Z</kbd>, type
|
|
a command and then would use `fg`<kbd>↵ Enter</kbd> to switch back to Vim.
|
|
Having to type in the `fg` part really hurt me.
|
|
I just wanted to hit <kbd>Ctrl</kbd>-<kbd>Z</kbd> once again to get back to Vim.
|
|
I could not find a solution, so I developed one on my own that works wonderfully
|
|
with Zsh.
|
|
|
|
Switching between the last two suspended jobs is motivated by both TV remotes
|
|
that had such feature, and tools like `cd -` and `git checkout -` that switch
|
|
between the current and the second most recent state (directory, branch, etc.).
|
|
Sometimes, you have your Vim where code is changed, and another longer-running
|
|
process (e.g., a `tail` on some logs, or a Python interpreter) where you want
|
|
to test or observe your changes.
|
|
There is no point in time where you would "have the editor open" and "have the
|
|
program open" together, and the workflow clearly mandates always switching
|
|
back and forth between the two.
|
|
That's why the original version of _fancy-ctrl-z_ was extended with this "even
|
|
fancier" behaviour, because the original version would've opened Vim back again
|
|
and again.
