Using '|' as the data separator caused crashes if
a path with a '|' char in it was in the data file.
Changing that separator to a null byte ensures
that this kind of issue can never happen again as
the null byte can't be in a path.
- Introduced new environment variable _ZL_ZSH_FZF to specify the fzf command
- Updated the eval statement to use the custom fzf command if provided by the user
Previously, you needed to set `_ZL_HYPHEN=1` to treat `-` as a normal
character. Otherwise, it was treated as a Lua regexp special character, see
https://www.lua.org/pil/20.2.html. Note that it is not super-useful to treat
`-` as a special character; it is almost the same as `*` and the difference
is not very useful in the context of fuzzy matching.
Now, if `_ZL_HYPHEN` is not set, z.lua first tries to treat it as a regexp
character. If there are no results (which is likely if the user does not know
it's a special character), z.lua tries again, treating `-` as a normal
character this time.
If `_ZL_HYPHEN=0` or `_ZL_HYPHEN=1`, z.lua will always treat `-` as
either a regex symbol or as a normal character (respectively).
Hopefully, this will make the FAQ at
https://github.com/skywind3000/z.lua/wiki/FAQ#how-to-input-a-hyphen---in-the-keyword-
unnecessary. It took me weeks to look into the question of why `z
home-manager` refused to work and to find that FAQ.
I only tested this briefly, but it seems to work.
1. `alias` command not available in some fishshell versions like 3.3.1. use fish-native `function` instead;
2. add autocompletion for cmd options benefitting from magic power of fish. just type `z -` and press tab. enjoy yourself.
If `z -b foo bar` finds no exact match in the path to the current directory,
it tries a "fuzzy" substitution with a frecent directory. For example, if
we are in `~/github/jekyll/test` and run `z -b jek gh`, it will try to
substitute the entire `jekyll` path component with `gh`. The result will
be equivalent to running `z ~/github gh test`.
- Makes Ranger plugin use the standard `$ZLUA_LUAEXE` and `$ZLUA_SCRIPT`
environment variables that `z.lua` itself uses.
- Better error handling; errors loading plugin no longer cause
`ranger` to quit entirely.
- Briefly document the plugin
`.zlua` file doesn't get created for Powershell users that use [Starship Prompt](https://starship.rs/) and place z.lua init command before starship init command in their `profile.ps1`.
Couldn't reproduce the bug in zsh. Didn't test other shells.
