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

fish can be installed:
- using `Homebrew <http://brew.sh/>`__: ``brew install fish``

Running fish
------------
Once installed, run ``fish`` from your current shell to try fish out!
Dependencies
~~~~~~~~~~~~
Running fish requires:
Revert "README: note dependency on tput" This reverts commit 50398ea9f5300170e149436750429396f2a35e35. tput is only required as a fallback for backward compatibility.
2021-03-28 01:10:44 +00:00
- curses or ncurses (preinstalled on most \*nix systems)

messages require ``ul`` and either ``nroff`` or ``mandoc`` for
display

bindings) require either the ``xsel``, ``xclip``,
``wl-copy``/``wl-paste`` or ``pbcopy``/``pbpaste`` utilities
- full completions for ``yarn`` and ``npm`` require the

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).

Dependencies
~~~~~~~~~~~~
Compiling fish requires:
- a C++11 compiler (g++ 4.8 or later, or clang 3.3 or later)
CMake: bump minimum requirement to 3.5 CMake 3.5.0 was released in March 2016.
2021-06-28 15:56:02 +00:00
- CMake (version 3.5 or later)

2020-05-28 15:07:51 +00:00
- 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.

Additionally, running the test suite requires Python 3.5+ and the pexpect package.

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``.
README: Document build options
2021-06-06 10:21:32 +00:00
Build options
~~~~~~~~~~~~~
In addition to the normal cmake build options (like ``CMAKE_INSTALL_PREFIX``), fish has some other options available to customize it.
- BUILD_DOCS=ON|OFF - whether to build the documentation. This is automatically set to OFF when sphinx isn't installed.
- INSTALL_DOCS=ON|OFF - whether to install the docs. This is automatically set to on when BUILD_DOCS is or prebuilt documentation is available (like when building in-tree from a tarball).
- FISH_USE_SYSTEM_PCRE2=ON|OFF - whether to use an installed pcre2. This is normally autodetected.
- MAC_CODESIGN_ID=String|OFF - the codesign ID to use on Mac, or "OFF" to disable codesigning.
- WITH_GETTEXT=ON|OFF - whether to build with gettext support for translations.
Note that fish does *not* support static linking and will attempt to error out if it detects it.

2020-05-28 15:07:51 +00:00
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
