- Optimize startup path #494
- Cuts fisher-related startup time to roughly 25ms
- Reduce legacy fish support (~~>=2.0~~ >=2.1)
- Read fishfile from `$fisher_path` instead of `$fish_config` #480, #479
- Don't add invalid packages to fishfile / validate fishfile #478#484#492
- Rewrite tar expansion logic / don't use `--strip-components` #489#496
- Better OpenBSD support
- Better msys2 on Windows 10 support
- Create symbolic links of original files when adding local packages #502
* With the addition of keybinding support for fish 2.x, fisher greatly
increases shell startup time (50-100ms in my testing). This is due to a
number of reasons, including using less-than-ideal builtins,
unconditionally running mkdir, unconditionally recreating
conf.d/fisher.fish, and checking for curl on startup (instead of when
curl is used).
* This patch cuts fisher-related startup time to roughly 25ms, simplifying
the code paths as much as I am able.
* The source function is removed as a compromise for speed. Fish 2.1 and
greater support `source`, and supporting fish 2.0 is not worth a hefty
speed penalty in my opinion.
* Remove curl checks, invert version logic.
* Update README to reflect fish 2.1+ requirement
SUMMARY
This PR rewrites fisher from the ground up and adds new
documentation. It introduces some breaking changes as described
in the next section. For a historical background of this work
see the original V3 proposal #307 and the more recent discussion
about the future of the project #443.
After much debate and careful consideration I decided it is in
the best interest of the project to keep the CLI-based approach
to dependency management as a facade to the fishfile-based
approach originally proposed.
The new `add` commands (previously `install`) and good ol' `rm`
interactively update your fishfile and commit all your changes
in one sweep. To the end user, it's as if you were adding or
removing packages like you already do now. Internally, these
commands affect how the fishfile is parsed and result in adding
new or replacing/removing existing entries followed by a regular
`fisher` run.
INSTALLING
- `install` has been renamed to `add`
- Installing from a gist is no longer supported (but it will be
back in a future release—removed only to simplify the rewrite)
- To install a package from a tag or branch use an at symbol
`@`—the colon `:` is deprecated
LISTING
- `ls` and `rm` are still available with a few minor differences
- `ls` followed by a package name does not list specific package
information (may be added back in a future release)
- `ls` output format no longer displays a legend to indicate
whether a package is a theme or a local package; now it's a flat
dump of every installed package specifier
- For local packages the full path is shown instead
- I want to add a `--tree` option in to display packages in a
tree-like format in the future
- `ls-remote` has been removed as there is no longer a preferred
organization to look for packages— there is no plan to add it
back
UPDATING
- A new `self-update` command has been introduced to update
fisher itself
- fisher will be only updated when a new version is actually
available
- `update` has been removed
- Everything is installed from scratch everytime you add or
remove something, so there is no need to update specific
packages—you're always up-to-date
- To lock on a specific package version install from a
tag/branch, e.g., `mypkg/foobar@1.3.2`
UNINSTALLING
- `self-uninstall` works as usual
HELP & VERSION
- `help` only displays fisher usage help
- help is dumped to stdout instead of creating a man page on the
fly and piping it to your pager `version` works as usual
ENVIRONMENT
- `$fish_path` been renamed to `$fisher_path` to make it clear
that this is a fisher specific extension, not your shell's
ECOSYSTEM
- Oh My Fish! packages are still supported, albeit less
attention is paid to them
- Some packages that use Oh My Fish! specific environment
variables or events might not work
- Most of Oh My Fish! extensions are no longer necessary since
fish 2.3, therefore it should be a simple matter to upgrade them
to modern fish
DEPENDENCIES
- fisher can now run on fish 2.0
- It's a good idea to upgrade to at least fish 2.3 to use the
string builtin and configuration snippets, but there's no reason
for fisher to force you to use any fish version
- `curl` is required for fetching packages
- I am considering adding a fallback to `wget` if `curl` is not
available on your system
- `git` is optional
- V3 fetches packages directly from github, gitlab and
bitbucket, if you are using them
- git is only used (implementation still wip) if you want to
install a package from an unknown git host like your own git
server
* Ensure fisherman's completions are placed in the correct fisherman directory when running self update.
* Update documentation to include the extra steps required when setting fish_path.
* -U instead of -g in README.
