> The Fishshell Framework [](/LICENSE.md) [](http://fishshell.com) [](https://travis-ci.org/oh-my-fish/oh-my-fish) [](https://oh-my-fish-slack.herokuapp.com) Oh My Fish provides core infrastructure to allow you to install packages which extend or modify the look of your shell. It's fast, extensible and easy to use. > Also in  > 🇷🇺 > 🇨🇳 > 🇺🇦 > 🇧🇷
## Installation You can get started right away with the default setup by running this in your terminal: ```fish curl -L https://get.oh-my.fish | fish ``` This will download the installer script and start the installation. Alternatively, you can download the installer and customize your install: ```fish curl -L https://get.oh-my.fish > install fish install --path=~/.local/share/omf --config=~/.config/omf ``` You can verify the integrity of the downloaded installer by verifying the script against [this checksum](bin/install.sha256): ``` 92ca680df48640e744b361d376194c5f5f8d6b4f1ac775d22417a0d8a8108767 install ``` You can also install Oh My Fish with Git or with an offline source tarball downloaded from the [releases page][releases]: ```fish # with git $ git clone https://github.com/oh-my-fish/oh-my-fish $ cd oh-my-fish $ bin/install --offline # with a tarball $ curl -L https://get.oh-my.fish > install $ fish install --offline=omf.tar.gz ``` Run `install --help` for a complete list of install options you can customize. ## Getting Started Oh My Fish includes a small utility `omf` to fetch and install new packages and themes. #### `omf update` _`[omf]`_ _`[...]`_ Update Oh My Fish, all package repositories, and all installed packages. - When called without arguments, update core and all installed packages. - You can choose to update only the core, by running `omf update omf`. - For selective package update, list only the names of packages you wish to update. You may still include "omf" in the list to update the core as well. #### `omf install` _`[|]`_ Install one _or more_ packages. - You can install packages directly by URL via `omf install URL` - When called without arguments, install missing packages from [bundle](#dotfiles). #### `omf repositories` _`[list|add|remove]`_ Manage user-installed package repositories. Package repositories are where packages come from used by commands like `omf install`. By default the [official repository](https://github.com/oh-my-fish/packages-main) is always installed and available. #### `omf list` List installed packages. #### `omf theme` _``_ Apply a theme. To list available themes, type `omf theme`. You can also [preview available themes](./docs/Themes.md) before installing. #### `omf remove` _``_ Remove a theme or package. > Packages can use uninstall hooks, so custom cleanup of resources can be done when uninstalling it. See [Uninstall](/docs/en-US/Packages.md#uninstall) for more information. #### `omf reload` Reload Oh My Fish and all plugins by using `exec` to replace current shell process with a brand new. > This command tries to be as safe as possible, mitigating side-effects caused by `exec` and preventing the reload in case of background processes. #### `omf new pkg | theme` _``_ Scaffold out a new package or theme. > This creates a new directory under `$OMF_CONFIG/{pkg | themes}/` with a template. #### `omf search` _`-t|--theme / -p|--package`_ _``_ Searches Oh My Fish's database for a given package, theme or both. It also supports fuzzy search, so if you are not sure of the name you can simply `omf search simple`. #### `omf channel` Gets or changes the update channel. Two channels are available by default: the `stable` channel provides stable updates with the latest tagged version of Oh My Fish, and `dev` which provides the latest changes under development. The update channel currently set determines what version `omf update` will upgrade to. #### `omf doctor` Use to troubleshoot before [opening an issue][omf-issues-new]. #### `omf destroy` Uninstall Oh My Fish. ## Advanced Oh My Fish installer places its startup code in your fish config file (`~/.config/fish/config.fish`). ### Startup Every time you open a new shell, the startup code initializes Oh My Fish installation path and the _config_ path (`~/.config/omf` by default), sourcing the [`init.fish`](init.fish) script afterwards, which autoloads packages, themes and your custom init files. For more information check the [FAQ](docs/en-US/FAQ.md#what-does-oh-my-fish-do-exactly). ### Dotfiles The `$OMF_CONFIG` directory represents the user state of Oh My Fish. It is the perfect candidate for being added to your dotfiles and/or checked out to version control. There are four important files: - __`theme`__ - The current theme - __`bundle`__ - List of currently installed packages/themes - __`init.fish`__ - Custom script sourced after shell start - __`before.init.fish`__ - Custom script sourced before shell start - __`key_bindings.fish`__ - Custom key bindings where you can use the `bind` command freely It's highly recommended that your custom startup commands go into `init.fish` file instead of `~/.config/fish/config.fish`, as this allows you to keep the whole `$OMF_CONFIG` directory under version control. If you need startup commands to be run *before* Oh My Fish begins loading plugins, place them in `before.init.fish` instead. If you're unsure, it is usually best to put things in `init.fish`. #### Setting variables in `init.fish` One of the most common startup commands used in `init.fish` is variables definition. Quite likely, such variables need to be available in any shell session. To achieve this, define them globally. For example: ```fish # Golang developers might need this one set -xg GOPATH $HOME/gocode # Python developers otherwise set -xg PYTHONDONTWRITEBYTECODE 1 ``` #### About the bundle Every time a package/theme is installed or removed, the `bundle` file is updated. You can also edit it manually and run `omf install` afterwards to satisfy the changes. Please note that while packages/themes added to the bundle get automatically installed, a package/theme removed from bundle isn't removed from user installation. ## Creating Packages Oh My Fish uses an advanced and well defined plugin architecture to ease plugin development, including init/uninstall hooks, function and completion autoloading.
