It is similar in spirit to xmobar, but it differs in that it gives up some simplicity for a reasonable helping of eye candy. -Prerequisites--------------+Before Installing+----------------- -Taffybar has a number of non-haskell dependencies. It is recommended that you-follow the installation instructions for-[haskell-gi](https://github.com/haskell-gi/haskell-gi) before attempting to-install taffybar.+The installation method, and procedure that must be followed depends on whether+or not you intend to setup a new haskell project and use `startTaffybar`, or if+you want to use the `dyreTaffybar` approach. It is important for you to read+this section so you can understand what all of that means before you decide how+you want to install taffybar. -In addition the the dependencies needed by haskell-gi, taffybar also needs the-equivalent of `libdbusmenu-gtk3-dev` and `libgirepository1.0-dev` on Debian.+### Taffybar is a library -Installation-------------+As with window managers like XMonad and dwm, taffybar is most appropriately+described as a library that allows you to build an executable that is customized+to your tastes. This means that taffybar must be installed alongside a haskell+compiler (ghc) that can compile the user's configuration source file. -Taffybar itself can be installed in a number of different ways:+### The taffybar binary and `startTaffybar` vs `dyreTaffybar` -### Stack+Taffybar can be started from your configuration file in two different ways: -Though it is admittedly a bit complicated to set up properly, using stack is the-preferred approach for installing taffybar, because it makes the build process-stable and repeatable. Even if you are unfamiliar with stack, or even haskell in-general, you should be able to get things working by using the taffybar's-quick-start script:+#### `dyreTaffybar` -```-curl -sSL https://raw.githubusercontent.com/taffybar/taffybar/master/quick-start.sh | bash-```+The `dyreTaffybar` entry point to taffybar uses the [dyre+library](https://github.com/willdonnelly/dyre) to automatically recompile your+taffybar configuration whenever it detects that it has changed. The binary that+is distributed with taffybar does nothing more than call this entry point. The+main downside of this approach is that it does not allow the user to use any+sort of project files for their configuration, and they must have any packages+that are necessary for compilation of their configuration available in their+global ghc environment. -This script will clone the taffybar repository into a subdirectory of the-default taffybar configuration directory, and copy the example cabal, stack and-taffybar.hs files into the same location. It will then install a binary-`my-taffybar` to `$HOME/.local/bin`, which can be executed to run taffybar. Note-that with this approach, running the `taffybar` binary WILL NOT work; you must-run the binary that is produced by the stack build in your local directory. The-name of the binary can be changed in the cabal file in the taffybar-configuration directory.+#### `startTaffybar` -#### Running with stack+The `startTaffybar` entry point to taffybar simply starts taffybar with the+provided configuration. The user binary will not be automatically recompiled+when source files change. The advantage of using `startTaffybar` directly is+that you can use that in the main function of a cabal project. -When you build with stack, it is recommended that you start taffybar with-`startTaffybar` rather than `dyreTaffybar`, and use-https://github.com/yamadapc/stack-run to execute the custom executable specified-by your cabal and stack files. The maintainers have plans for a better solution-(that does not require the user to use stack-run themselves) in [#158](https://github.com/taffybar/taffybar/issues/158).+Distribution Packaging+----------------------+Several linux distributions package taffybar+([nixos](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/window-managers/taffybar/default.nix),+[arch/aur](https://aur.archlinux.org/packages/taffybar/),+[debian](https://aur.archlinux.org/packages/taffybar/)). Of these, only the+NixOS distribution is officially supported by the maintainers. Using any of the+others should be pretty similar to using a bare cabal installation of taffybar. +#### NixOS++If you wish to use the NixOS package for taffybar, make sure that you are using+the+[module](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/window-managers/taffybar/default.nix),+and not simply the haskellPackage for taffybar. If you need to add additional+haskell packages to the environment that compiles your taffybar.hs you will need+to invoke that module and use the packages parameter to allow this.++Installation From Hackage/Source+--------------------------------++### Prerequisites++If you are not using distribution packaging of taffybar or the nix package+manager (it will handle getting all the necessary packages for you), you will+need to install all of taffybar's non-haskell dependencies manually.++Start by making sure you have installed everything that is needed for [haskell-gi](https://github.com/haskell-gi/haskell-gi). Taffybar also needs the+equivalent of `libdbusmenu-gtk3-dev` and `libgirepository1.0-dev` on Debian.++You can also get some idea of what the necessary dependencies are by looking at+the nix section of the stack.yaml file in the taffybar repository.+ ### Cabal  Cabal installation is a simple matter of installing taffybar from hackage: ``` cabal install taffybar ```++You do not need to do this if you are using the project approach with cabal.++### The project approach+The project approach to installing/using taffybar involves maintaining a small+haskell project that produces the users taffybar binary. No matter which package+manager you choose to use you will need to make a .cabal file for this project.+It is recommended that you use [this+example](https://github.com/taffybar/taffybar/blob/master/example/my-taffybar.cabal)+as a template. In that example, the users configuration resides in the file+`taffybar.hs` in the same directory, but that can be changed as needed. As of+right now, `dyreTaffybar` is incompatible with this approach because dyre simply+calls ghc directly.++### Cabal++Simply run `cabal new-install` to install the binary.++### Stack++With stack, you will also need to maintain a stack.yaml file. Run `stack+install` to install the binary. See [this+example](https://github.com/taffybar/taffybar/blob/master/example/stack.yaml)++### Nix++You will need to add default.nix file to your package.
