This commit adds an improved reload code for Oh My Fish, besides
saving the history now the reloading technique keeps directory
history and stack and clears fish_greeting, for a transparent
transition.
The reloading code is now safe regarding to background jobs. exec
wipes fish job control, so the user-facing code under the (just-
introduced by this commit) `omf reload` command is kept safe by a
warning. For testing purposes, `omf update` and `omf remove` rolls
automatic refresh only when `OMF_AUTO_RELOAD` variable is set.
Recap of the commit:
- Add improved reload code (omf.reload)
- Add a safe reload code (omf.cli.reload)
- Add `omf reload` command
- Add opt-in reload to `omf update` and `omf remove` commands
With great power comes great responsibility. This function is
somewhat low level, and is harmful to shell's user, as it
completely screws up with job control (subprocesses).
This PR officially marks `refresh` as deprecated, moving the
deprecated functionality to omf plugin `compat` quarantine
directory.
This updates omf plugin to new architecture, moving
functions to `functions` directory. It also revamps the
separation of concerns between CLI and underlying
implementations, organizing them into directories,
whose are autoloaded in plugin startup.
When using basename without any arguments, a usage helper as following
is displayed:
```
usage: basename string [suffix]
basename [-a] [-s suffix] string [...]
```
When listing the installed packages, if no theme was installed (e.g.
first installation), the `themes/` folder are empty and the usage helper
is displayed. This change addresses it by suppressing the message.
Since `test` interprets arguments starting with a single dash as
options when comparing `test -h = --help` just swap parameter
orders as in `test --help = -h`. Also related to issue #161 is the
issue from fish repository at fish-shell/fish-shell#2332
As #115 migrated list functions, after updating Oh My Fish code
the omf.list_installed_packages gets removed, but is still being
used by the update code.
This commit fixes it by providing a wrapper function.
- Move theme installation to cli entry point (omf.fish)
- Generalize XDG_CONFIG_HOME code in `omf.xdg.config_home`
- Generalize prompt conflicts check in `omf.checks.fish_prompt`
* Migrate `omf.doctor` to use it
+ Change theme activation steps
- Create user function path if not existent
- Check for conflicts in fish_prompt, aborts if found
- Remove current theme from autoloading paths
- Add target theme to autoloading paths
- Link target theme's fish_prompt to user's
- Persist selected theme to $OMF_CONFIG/theme
This approach brings two major advantages:
- Theme prompt now shows accordingly in fish_config web interface
- Faster theme changes, reducing it from seconds to some milis
- Avoids calling refresh, which makes users much more happy
Instead of having every plugin function inside the same file, which
increases the loading time unnecessarily and is not fishy, source the
`uninstall.fish` file for the plugin before the `uninstall_$plugin_name`
event is emitted.
