Convert Markdown files to RST We use sphinx with rst for our documentation, and github supports rst here, so it seems weird to have markdown just for these. It also allows us e.g. to include the CHANGELOG in the docs without requiring another build dependency.

`fish <https://fishshell.com/>`__ - the friendly interactive shell |Build Status|
=================================================================================
fish is a smart and user-friendly command line shell for macOS, Linux,
and the rest of the family. fish includes features like syntax
highlighting, autosuggest-as-you-type, and fancy tab completions that
just work, with no configuration required.
For more on fish’s design philosophy, see the `design
document <https://fishshell.com/docs/current/design.html>`__.
Quick Start
-----------
fish generally works like other shells, like bash or zsh. A few
important differences can be found at
https://fishshell.com/docs/current/tutorial.html by searching for the
magic phrase “unlike other shells”.
Detailed user documentation is available by running ``help`` within
fish, and also at https://fishshell.com/docs/current/index.html
You can quickly play with fish right in your browser by clicking the

Getting fish
------------
macOS
~~~~~
fish can be installed:
- using `Homebrew <http://brew.sh/>`__: ``brew install fish``
- using `MacPorts <https://www.macports.org/>`__:
``sudo port install fish``
- using the `installer from fishshell.com <https://fishshell.com/>`__
- as a `standalone app from fishshell.com <https://fishshell.com/>`__
Packages for Linux
~~~~~~~~~~~~~~~~~~
Packages for Debian, Fedora, openSUSE, and Red Hat Enterprise
Linux/CentOS are available from the `openSUSE Build
Service <https://software.opensuse.org/download.html?project=shells%3Afish&package=fish>`__.
Packages for Ubuntu are available from the `fish
PPA <https://launchpad.net/~fish-shell/+archive/ubuntu/release-3>`__,
and can be installed using the following commands:
::
sudo apt-add-repository ppa:fish-shell/release-3
sudo apt-get update
sudo apt-get install fish
Instructions for other distributions may be found at
`fishshell.com <https://fishshell.com>`__.
Windows
~~~~~~~
- On Windows 10, fish can be installed under the WSL Windows Subsystem
for Linux with the instructions for the appropriate distribution
listed above under “Packages for Linux”, or from source with the
instructions below.
- Fish can also be installed on all versions of Windows using
`Cygwin <https://cygwin.com/>`__ (from the **Shells** category).
Building from source
~~~~~~~~~~~~~~~~~~~~
If packages are not available for your platform, GPG-signed tarballs are
available from `fishshell.com <https://fishshell.com/>`__ and
`fish-shell on
GitHub <https://github.com/fish-shell/fish-shell/releases>`__. See the
*Building* section for instructions.
Running fish
------------
Once installed, run ``fish`` from your current shell to try fish out!
Dependencies
~~~~~~~~~~~~
Running fish requires:
- curses or ncurses (preinstalled on most \*nix systems)
- some common \*nix system utilities (currently ``mktemp``), in
addition to the basic POSIX utilities (``cat``, ``cut``, ``dirname``,
``ls``, ``mkdir``, ``mkfifo``, ``rm``, ``sort``, ``tee``, ``tr``,
``uname`` and ``sed`` at least, but the full coreutils plus find, sed
and awk is preferred)
- gettext (library and ``gettext`` command), if compiled with
translation support
The following optional features also have specific requirements:
- builtin commands that have the ``--help`` option or print usage
messages require ``ul`` and either ``nroff`` or ``mandoc`` for
display
- automated completion generation from manual pages requires Python
(2.7+ or 3.3+) and possibly the ``backports.lzma`` module for Python
2.7
- the ``fish_config`` web configuration tool requires Python (2.7+ or
3.3 +) and a web browser
- system clipboard integration (with the default Ctrl-V and Ctrl-X
bindings) require either the ``xsel``, ``xclip``,
``wl-copy``/``wl-paste`` or ``pbcopy``/``pbpaste`` utilities
- full completions for ``yarn`` and ``npm`` require the
``all-the-package-names`` NPM module
Switching to fish
~~~~~~~~~~~~~~~~~
If you wish to use fish as your default shell, use the following
command:
::
chsh -s /usr/local/bin/fish
``chsh`` will prompt you for your password and change your default
shell. (Substitute ``/usr/local/bin/fish`` with whatever path fish was
installed to, if it differs.) Log out, then log in again for the changes
to take effect.
Use the following command if fish isn’t already added to ``/etc/shells``
to permit fish to be your login shell:
::
echo /usr/local/bin/fish | sudo tee -a /etc/shells
To switch your default shell back, you can run ``chsh -s /bin/bash``
(substituting ``/bin/bash`` with ``/bin/tcsh`` or ``/bin/zsh`` as
appropriate).
Building
--------
.. _dependencies-1:
Dependencies
~~~~~~~~~~~~
Compiling fish requires:
- a C++11 compiler (g++ 4.8 or later, or clang 3.3 or later)
- CMake (version 3.2 or later)
- a curses implementation such as ncurses (headers and libraries)
- PCRE2 (headers and libraries) - a copy is included with fish
- gettext (headers and libraries) - optional, for translation support
Sphinx is also optionally required to build the documentation from a
cloned git repository.
Building from source (all platforms) - Makefile generator
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To install into ``/usr/local``, run:
.. code:: bash
mkdir build; cd build
cmake ..
make
sudo make install
The install directory can be changed using the
``-DCMAKE_INSTALL_PREFIX`` parameter for ``cmake``.
Building from source (macOS) - Xcode
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. code:: bash
mkdir build; cd build
cmake .. -G Xcode
An Xcode project will now be available in the ``build`` subdirectory.
You can open it with Xcode, or run the following to build and install in
``/usr/local``:
.. code:: bash
xcodebuild
xcodebuild -scheme install
The install directory can be changed using the
``-DCMAKE_INSTALL_PREFIX`` parameter for ``cmake``.
Help, it didn’t build!
~~~~~~~~~~~~~~~~~~~~~~
If fish reports that it could not find curses, try installing a curses
development package and build again.
On Debian or Ubuntu you want:
::
sudo apt-get install build-essential cmake ncurses-dev libncurses5-dev libpcre2-dev gettext
On RedHat, CentOS, or Amazon EC2:
::
sudo yum install ncurses-devel
