* Fix a critical bug in the Makefile that was incorrectly merging any existing user configuration file and the generated Fisherman configuration. Closes #21. * Fix a bug in install and uninstall that was adding plugin names to fishfiles instead of the URL when interacting with custom URLs. Probably closes #23. * Fix a bug in install, update and uninstall that was displaying an incorrect plugin count if there was at least on failure. * Fix bug in `fisher install` that causes install to fail even though it succeeds, due to `wait(1)`'s behavior of returning `1` if there is any output to standard error. Closes #20. * Fix bug in `fisher uninstall` that was removing plugins from the cache by mistake. * Add feature to Makefile to download the index for the first time in order to provide auto-complete before the user can install/update/search, actions which would case the index to be updated. * Add link to Slack [room][wharf] in README. Thanks @simnalamburt. * Add new `$fisher_timeout` configuration variable that lets you specify `curl(1)` `--max-time` option. Without this, `curl` could hang for a long time if you are in a bad connection. * Add `fisher install --link` to allow installing plugins creating a symbolic link to each of the relevant files to be copied during the install process. If you use ***`--link`*** to install a plugin that is a _path to a directory_ or file, a symbolic link to the directory will be created making local testing more convenient as you are not required to update the plugin's repository to test changes within Fisherman. If you are testing using [Fishtape][fishtape] you do not even need to reset the shell session. * Add `fisher --alias[=<command>=<alias>]` to simplify creating new aliases for `fisher` commands. Use `fisher --alias` without arguments to list the current set of aliases. Also add auto-complete for aliases to install, update or uninstall. Note that aliases are **not** persisted this way. To save your aliases use `$fisher_alias` as described in `fisher help config`. Also note that aliases are only auto-complete if you call `fisher --alias`. To auto-complete aliases saved to `$fisher_alias` you can do `fisher --alias (fisher --alias)`. * Add short options for new and old fisher flags: * `--file` → `-f` * `--list` → `-l` * `--alias` → `-a` * Improve help message for failed installs. Closes * Improve `fisher --validate` to automatically correct common misspellings, for example when installing a oh-my-fish package, one often types ohmyifsh. * ☝️ Improve auto-complete performance by extracting the implementation of the different `fisher` flags to `__fisher_*` functions. `completions/fisher.fish` relies heavily in `fisher_search` to query what plugins are available to install/update/uninstall. In this process, numerous calls to `fisher --list` and `fisher --validate`, etc., are made. Now, auto-complete does not have to pay the penalty of entering `fisher`, parsing options, etc. Closes #27. @namandistro * Improve `fisher --help` output and show up until now poorly documented ***`--list`***, ***`--file`***, etc. flags consistently. Also display available commands after `make install` to improve usability. * Improve `fisher install` so that it checks whether the plugin you are trying to install, if it is already in the cache, is a symbolic link or not, and installs it as if the `--link` flag was specified. * Improve `fisher --validate` to retrieve the absolute path to the closest directory of the given items if they are valid local paths. Related #19. * Improve install to not `git clone` local plugins if a regular `path/to/file` is given to `fisher install`. Instead, copy to the cache using `cp(1)` and if `--link` is used, create a symlink. * Improve `fisher --validate` to invalidate items with repeated `.` and `-` and allow items that begin with `/` or `./` to support installing plugins from local paths. Related #19. * Modify `fisher update` default behavior. Now this command updates Fisherman by default. Use of `--self` and `--me` is also **deprecated**. To read from the standard input use a dash `-`. For example: `fisher --list | fisher update -`. Closes #25. * Rename `--cache` to more descriptive ***`--list`***. Thanks @colstrom. * Remove `fisher --cache=base` and make it return the base names of all directories in the path by default. To get the full path use printf `printf "$fisher_cache/%s" (fisher --list)` * Rename undocumented `fisher --translate` flag (again) to `fisher --cache`. This function reads the standard input for a name, URL or local path and calculates the plugin's path relative to the cache. For a name this is simple `$fisher_cache/<name>` for an URL, retrieve the remote URL of every repository until there is a match with the given URL and return the path in the cache of that repository. Finally, if the input is a * Revert #3. The reason `getopts.fish` was in its own file originally is because @bucaran wanted a standalone, dependency free cli parser solution, arguably slightly faster than having Awk read `getopts.awk` for each use. The performance improvement is negligible at best, but `getopts` is also used by every single command and future commands and plugins are very likely to use it as well, so we so we might as well use the slightly faster version.

|
|
\fBfisher\fR \- An Introduction to Fisherman
|
|
.
|
|
.SH "DESCRIPTION"
|
|
Fisherman is a plugin manager for \fBfish\fR(1) that lets you share and reuse code, prompts and configurations easily\.
|
|
.
|
|
.P
|
|
Some features include: minimalistic design, flat tree structure, unified plugin architecture, external self\-managed database, cache system, dependency manifest file and compatibility with oh-my-fish and other frameworks\.
|
|
.
|
|
.P
|
|
This document describes Fisherman features and some of their implementation details\. For usage and command help see also \fBfisher\fR(1)\.
|
|
.
|
|
.SH "FLAT TREE"
|
|
The configuration directory structure is optimized to help fish start new sessions as quickly as possible, regardless of the numbers of plugins or prompts enabled at any given time\.
|
|
.
|
|
.P
|
|
To explain how this is possible, we need to make a digression and discuss function scope first\. In fish, all functions share the same scope and you can use only one name per function\.
|
|
.
|
|
.P
|
|
In the following example:
|
|

function foo
|
|
echo $_
|
|
function bar
|
|
end
|
|
end
|
|
|
|
function bar
|
|
echo $_
|
|
end

|
|
\fIfoo\fR and \fIbar\fR are available immediately at the command line prompt and both print their names\. But there is a catch, calling \fIfoo\fR at least once will create a new \fIbar\fR function, effectively erasing the previous \fIbar\fR definition\. Subsequent calls to \fIbar\fR will print nothing\.
|
|
.
|
|
.P
|
|
By convention, functions that start with any number of underscores are \fIintentionally\fR private, but there is no mechanism that prevents you from calling them at any time once loaded\.
|
|
.
|
|
.P
|
|
With this in mind, it\'s possible to improve the slow shell start problem using a \fIflat\fR tree structure whose path is loaded only once\.
|
|
.
|
|
.P
|
|
The overhead of juggling multiple path hierarchies in a per\-plugin basis yields no benefits as everything is shared in the same scope\.
|
|
.
|
|
.P
|
|
Loading a path simply means adding the desired location to the \fB$fish_function_path\fR array\. See also \fBfunctions\fR(1)\.

Here is a snapshot of a typical configuration path with a single plugin and prompt:

If you are already familiar in the way fish handles your user configuration, you will find the above structure similar to \fB$XDG_CONFIG_HOME/fish\fR\. See \fBhelp fish\fR#{\fBInitialization Files\fR} to learn more about fish configuration\.
|
|
.
|
|
.P
|
|
\fBconf\.d\fR, short for configuration directory, is used for initialization files, i\.e\., files that should run at the start of the shell\. Files that follow the naming convention \fIname\fR\.config\.fish are added there\.
|
|
.
|
|
.SS "PLUGINS"
|
|
Plugins are components that extend and add features to your shell\. To see what plugins are available use \fBfisher search\fR\. You can also type \fBfisher install\fR and hit \fItab\fR once to get full name completions and plugin information\. The same works for \fBfisher update\fR and \fBfisher uninstall\fR\.
|
|
.
|

|
|
To learn how to create plugins, see \fBfisher help plugins\fR\.
|

Because of Fisherman\'s flat tree model, there is no technical distinction between plugins or prompts\. Installing a prompt is equivalent to switching themes in other systems\. The interface is always \fIinstall\fR, \fIupdate\fR or \fIuninstall\fR\.
|
|
.
|
|
.P
|
|
Throughout this document and other Fisherman manuals you will find the term prompt when referring to the \fIconcept\fR of a theme, i\.e\., a plugin that defines a \fBfish_prompt\fR and / or \fBfish_right_prompt\fR functions\.
|
|
.
|
|
.SS "INDEX"
|
|
You can install, update and uninstall plugins by name, querying the Fisherman index, or by url using several of the variations described in #{\fBPlugins\fR}\. The index is a plain text flat database \fIindependent\fR from Fisherman\. You can use a custom index file by setting \fB$fisher_index\fR to your own file or url\. Redirection urls are not supported due to security and performance concerns\. See \fBfisher help config\fR\.
|
|
.
|
|
.P
|
|
A copy of the index is downloaded each time a query happens\. This keeps the index up to date and allows you to search the database offline\.
|
|
.
|
|
.P
|
|
The index is a list of records, each consisting of the following fields:
|
|
.
|
|
.IP "\(bu" 4
|
|
\fBname\fR, \fBurl\fR, \fBinfo\fR, \fBauthor\fR and one or more \fBtags\fR\.

|
|
You can also submit a new plugin manually and create a pull request\.
|
|

|
|
Now you can create a new pull request in the upstream repository\.
|
|
.
|
|
.SS "CACHE"
|
|
Downloaded plugins are tracked as Git repositories under \fB$fisher_cache\fR\. See \fBfisher help config\fR to find out about other Fisherman configuration variables\.
|
|
.
|
|
.P
|
|
When you install or uninstall a plugin, Fisherman downloads the repository to the cache and copies only the relevant files from the cache to the loaded function and / or completion path\. In addition, man pages are added to the corresponding man directory and if a Makefile is detected, the command \fBmake\fR is run\.
|
|
.
|
|
.P
|
|
The cache also provides a location for a local copy of the Index\.
|
|
.
|
|
.SS "FISHFILES"
|
|
Dependency manifest file, or fishfiles for short, let you share plugin configurations across multiple installations, allow plugins to declare dependencies, and prevent information loss in case of system failure\. See \fBfisher help fishfile\fR\.
|
|
.
|
|
.P
|
|
Here is an example fishfile inside \fB$fisher_config\fR:

|
|
The fishfile updates as you install / uninstall plugins\. See also \fBfisher help install\fR or \fBfisher help uninstall\fR\.
|
|
.
|
|
.P
|
|
Plugins may list any number of dependencies to other plugins in a fishfile at the root of each project\. By default, when Fisherman installs a plugin, it will also fetch and install its dependencies\. If a dependency is already installed, it will not be updated as this could potentially break other plugins using an older version\. For the same reasons, uninstalling a plugin does not remove its dependencies\. See \fBfisher help update\fR\.
|
|
.
|
|
.SS "CONFIGURATION"
|
|
Fisherman allows a high level of configuration using \fB$fisher_*\fR variables\. You can customize the home and configuration directories, debug log file, cache location, index source url, command aliases, etc\. See \fBfisher help config\fR\.
|
|
.
|
|
.P
|
|
You can also extend Fisherman by adding new commands and ship them as plugins as well\. Fisherman automatically adds completions to \fIcommands\fR based in the function \fIdescription\fR and usage help if provided\. See \fBfisher help help\fR and \fBfisher help commands\fR\.
|
|
.
|
|
.P
|
|
To add completions to standalone utility plugins, use \fBcomplete\fR(1)\.
|
|
.
|
|
.SS "CLI"
|
|
If you are already familiar with other UNIX tools, you\'ll find Fisherman commands behave intuitively\.
|
|
.
|
|
.P
|
|
Most commands read the standard input by default when no options are given and produce easy to parse output, making Fisherman commands ideal for plumbing and building upon each other\.
|
|
.
|
|
.P
|
|
Fisherman also ships with a CLI options parser and a background job wait spinner that you can use to implement your own commands CLI\. See \fBgetopts\fR(1) and \fBwait\fR(1)\.
|
|
.
|
|
.SH "COMPATIBILITY"
|
|
Fisherman supports oh-my-fish (Wahoo) themes and plugins by default, but some features are turned off due to performance considerations\.
|
|
.
|
|
.P
|
|
oh-my-fish evaluates every \fI\.fish\fR file inside the root directory of every plugin during initialization\. This is necessary in order to register any existing \fBinit\fR events and invoke them using fish \fBemit\fR(1)\.
|
|
.
|
|
.P
|
|
Since it is not possible to determine whether a file defines an initialization event without evaluating its contents first, oh-my-fish sources all \fI\.fish\fR files and then emits events for each plugin\.
|
|
.
|
|
.P
|
|
Not all plugins opt in the initialization mechanism, therefore support for this behavior is turned off by default\. If you would like Fisherman to behave like oh-my-fish at the start of each session, install the \fBomf\fR compatibility plugin\.
