Jorge Bucaran 888a9a0cf3 Ahoy! Fisherman 0.5.0
=====================

Add user key bindings support.

Recall   $fisher_home/functions  are   always  before   user
functions in  $fish_function_path. This was an  early design
decision  in order  to  prevent users  from redefining  core
functions by  mistake or by  means other than  using plugins
(recommended).  In other  words, you  are free  to create  a
plugin  that modifies  a  Fisherman core  function, but  you
can't redefine  a Fisherman function privately  by saving it
to your user config fish. If  you found a bug in a Fisherman
function,  instead  of  creating  a private  patch  send  it
upstream.  If  you  created  a  function  that  overrides  a
Fisherman  core  feature,  create  a plugin.  This  way  the
community can benefit from your  code whenever you are ready
to publish it.

By  default, Fisherman  provides no  fish_user_key_bindings,
so   if   the   user   has   already   defined   their   own
fish_user_key_bindings that one will not be affected.

Now,  plugins can  define their  own key  bindings inside  a
fish_user_key_bindings.fish or key_bindings.fish at the root
of their repository or inside a functions directory. You can
put your key  bindings inside a function or not.  If you put
it inside a function, the function  name must be the same as
the file without the .fish extension.

$fisher_config/bindings.fish   When   a  plugin   with   key
bindings  is  installed  for  the first  time  or  the  only
one  with bindings  is  uninstalled,  Fisherman will  modify
~/.config/functions/fish_user_key_bindings.fish  (or  create
it for  the first  time) and  add a single  line at  the top
of  the fish_user_key_bindings  function to  source the  new
$fisher_config/bindings.fish. All  the key  bindings defined
by the enabled/installed plugins  are concatenated and saved
to this file.

This mechanism has the following advantages:

Does not slow  down shell start. Does  not require Fisherman
to  provide  his   own  fish_user_key_bindings  by  default.
Honors  any previously  existing user  key bindings.  Allows
plugin  to  define  their   own  key  bindings  and  coexist
with  the  user's key  bindings.  If  the user  updates  his
fish_user_key_bindings, re-running the  function does update
the key bindings. Mega Refactoring

The   entire   source   code   of   Fisherman   received   a
major   revision  and   refactoring.   The  validation   and
install/uninstall mechanisms were thoroughly revised and and
broken down into smaller functions easier to test as well as
several other sub parts of the system.

Rewrite fisher  search and  remove features that  are mostly
already covered by  fisher --list and remove  the ability to
generate information  about plugins  of unknown  origin. The
decision  to remove  this feature  was based  in performance
concerns  and the  result  of thinking  about the  usability
and  whether it  was really  worth the  speed tradeoff.  The
conclusion is I would rather  have better performance and if
I need  to query a  plugins origin  I can always  use fisher
--list or fisher --list=url or fisher --list=author.

Add $fisher_update_interval to determine if the index should
update  or not  when a  search  query is  taking place.  The
default value is  10 seconds. This means the  index will not
be updated  if less than  10 seconds have elapsed  since the
last action that triggered an update in the first place. See

Improve Install/Uninstall/Update status  output. If a plugin
fails  to install  decrease the  total. If  any plugins  are
skipped because  they are already  installed in the  case of
fisher install  or available in  the cache, but  disabled in
the  case of  fisher uninstall  they are  collected into  an
array and displayed in a  new section n plugin/s skipped (a,
b, c) at the bottom of the report.

Improve test coverage.

Tightly coupled  functions were making  testing increasingly
difficult.  Most of  the test  effort was  basically testing
whether git  clone or git  pull. New separation  of concerns
makes tests  run faster and the  difficult install/uninstall
algorithms has better coverage now. Other

Now  __fisher_list  can  list  plugins  from  the  cache,  a
fishfile/bundle  and plugins  that are  installed/enabled or
disabled. This  removes __fisher_file  and combines  it with
__fisher_list. This  also removes fisher -f  and replaces it
with fisher -l <file> or fisher --list=<file>.

Rename __fisher_parse_help to __fisher_complete and have the
function create  the completions automatically.  This allows
you  to complete  your  commands with  parseable usage  help
faster.  The  original  design  was fine,  but  this  change
improves auto-complete performance so it was preferred.

Use __fisher_index_update when building file with Make. This
helps prevent  an error when  using a fish version  < 2.2.0.
See #55 #50 #48.

Add  __fisher_index_update to  update the  index and  remove
previously   undocumented   fisher  update   --index.   This
function  is  designed  to bypass  GitHub's  server  network
cache  passing  an  arbitrary  query  string  to  curl  like
$fisher_index?RANDOM_NUMBER.  This means  index updates  are
immediately available now.

Add fisher --list=url option to  display local plugin url or
path.

Add fisher  --list=bare option  to display local  plugins in
the cache without the * enabled symbol.

Prepend > to  the currently enabled theme  when using fisher
--list[=cache]. Related #49.

Prepend *  to plugin  names to  indicate they  are currently
enabled when using fisher --list[=cache]. See #49.

.TH "FISHER\-TOUR" "7" "January 2016" "" "fisherman"
.
.SH "NAME"
\fBfisher\-tour\fR \- Fisherman Tour
.
.SH "DESCRIPTION"
Fisherman is a plugin manager and CLI toolkit for Fish to help you build powerful utilities and share your code easily\.
.
.P
Fisherman uses a flat tree structure that adds no cruft to your shell, making it as fast as no Fisherman\. The cache mechanism lets you query the index offline and enable or disable plugins as you wish\.
.
.P
Other features include dependency management, great plugin search capabilities and full compatibility with Tackle, Wahoo and oh\-my\-fish themes and packages\.
.
.P
This document describes Fisherman features and their implementation details\. For usage and command help see \fBfisher(1)\fR\.
.
.SH "FLAT TREE"
The configuration directory structure is optimized to help your shell start new sessions as quickly as possible, regardless of the numbers of plugins or prompts enabled at any given time\. An old saying goes that Fisherman is as fast as no Fisherman\.
.
.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:
.
.IP "" 4
.
.nf
function foo
echo $_
function bar
end
end
function bar
echo $_
end
.
.fi
.
.IP "" 0
.
.P
\fIfoo\fR and \fIbar\fR are available immediately at the command line prompt and both print their names\. But there is a catch, calling \fIfoo\fR at least once will create a new \fIbar\fR function, effectively erasing the previous \fIbar\fR definition\. Subsequent calls to \fIbar\fR will print nothing\.
.
.P
By convention, functions that start with any number of underscores are \fIintentionally\fR private, but there is no mechanism that prevents you from calling them at any time once loaded\.
.
.P
With this in mind, it\'s possible to improve the slow shell start problem using a \fIflat\fR tree structure whose path is loaded only once\.
.
.P
The overhead of juggling multiple path hierarchies in a per\-plugin basis yields no benefits as everything is shared in the same scope\.
.
.P
Loading a path simply means adding the desired location to the \fB$fish_function_path\fR array\. See also \fBfunctions(1)\fR\.
.
.P
Here is a snapshot of a typical configuration path with a single plugin and prompt:
.
.IP "" 4
.
.nf
$fisher_config
|\-\- cache/
|\-\- conf\.d/
|\-\- |\-\- my_plugin\.config\.fish
|\-\- functions/
| |\-\- my_plugin\.fish
| |\-\- fish_prompt\.fish
| |\-\- fish_right_prompt\.fish
|\-\- completions/
| |\-\- my_plugin\.fish
|\-\- man/
|\-\- man1/
|\-\- my_plugin\.1
.
.fi
.
.IP "" 0
.
.P
If you are already familiar in the way fish handles your user configuration, you will find the above structure similar to \fB$XDG_CONFIG_HOME/fish\fR\. See \fBInitialization Files\fR in \fBhelp fish\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 \fB<name>\.config\.fish\fR 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 formatted plugin information\. The same works for \fBfisher update\fR and \fBfisher uninstall\fR\.
.
.P
To learn how to create plugins, see \fBfisher help plugins\fR\.
.
.P
You can install a plugin by their name, URL or path to a local project\.
.
.P
If you use a \fIname\fR, this must be listed in the index database\. See \fBIndex\fR\.
.
.IP "" 4
.
.nf
fisher install shark
.
.fi
.
.IP "" 0
.
.P
You can use an URL too if you have one\.
.
.IP "" 4
.
.nf
fisher install simnalamburt/shellder
.
.fi
.
.IP "" 0
.
.P
If the domain or host is not provided, Fisherman will use \fBhttps://github\.com\fR by default\.
.
.P
In addition, all of the following \fBowner/repo\fR variations are accepted:
.
.IP "\(bu" 4
owner/repo \fB>\fR https://github\.com/owner/repo
.
.br
.
.IP "\(bu" 4
\fIgithub\fR/owner/repo \fB>\fR https://github\.com/owner/repo
.
.br
.
.IP "\(bu" 4
\fIgh\fR/owner/repo \fB>\fR https://github\.com/owner/repo
.
.br
.
.IP "" 0
.
.P
Shortcuts to other common Git repository hosting services are also available:
.
.IP "\(bu" 4
\fIbb\fR/owner/repo \fB>\fR https://bitbucket\.org/owner/repo
.
.br
.
.IP "\(bu" 4
\fIgl\fR/owner/repo \fB>\fR https://gitlab\.com/owner/repo
.
.br
.
.IP "\(bu" 4
\fIomf\fR/owner/repo \fB>\fR https://github\.com/oh\-my\-fish/repo
.
.br
.
.IP "" 0
.
.P
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\.
.
.IP "" 0
.
.P
Fields are separated by a new line \fB\'\en\'\fR\. Tags are separated by one \fIspace\fR\. Here is a sample record:
.
.IP "" 4
.
.nf
shark
https://github\.com/bucaran/shark
Sparklines for your Fish
graph spark data
bucaran
.
.fi
.
.IP "" 0
.
.P
To submit a new plugin for registration install the \fBsubmit\fR plugin:
.
.IP "" 4
.
.nf
fisher install submit
.
.fi
.
.IP "" 0
.
.P
For usage see the bundled documentation \fBfisher help submit\fR\.
.
.P
You can also submit a new plugin manually and create a pull request\.
.
.IP "" 4
.
.nf
git clone https://github\.com/fisherman/fisher\-index
cd index
echo "$name\en$URL\en$info\en$author\en$tags\en\en" >> index
git push origin master
open http://github\.com
.
.fi
.
.IP "" 0
.
.P
Now you can create a new pull request in the upstream repository\.
.
.SS "CACHE"
Downloaded plugins are tracked as Git repositories under \fB$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$fisher_config\fR:
.
.IP "" 4
.
.nf
# my plugins
gitio
fishtape
# my links
github/bucaran/shark
.
.fi
.
.IP "" 0
.
.P
The fishfile updates as you install / uninstall plugins\. See also \fBfisher help install\fR or \fBfisher help uninstall\fR\.
.
.P
Plugins may list any number of dependencies to other plugins in a fishfile at the root of each project\. By default, when Fisherman installs a plugin, it will also fetch and install its dependencies\. If a dependency is already installed, it will not be updated as this could potentially break other plugins using an older version\. For the same reasons, uninstalling a plugin does not remove its dependencies\. See \fBfisher help update\fR\.
.
.SS "CONFIGURATION"
Fisherman allows a high level of configuration using \fB$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(1)\fR\.
.
.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(1)\fR and \fBwait(1)\fR\.
.
.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(1)\fR\.
.
.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 \fB*\.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 every session, install the \fBomf\fR compatibility plugin\.
.
.IP "" 4
.
.nf
fisher install omf
.
.fi
.
.IP "" 0
.
.P
This plugin also adds definitions for some of oh\-my\-fish Core Library functions\.
