- Get it from Hackage. Configure, compile and install Yi as you would do for any other Cabal package. See also above-mentioned (2.3 Platform Support).
- Setup configure fails with
Setup.hs: Package yi-0.4 can't be built on this system.
- It means that you have no UI package available. You need VTY or GTK2hs installed. Get them from Hackage.
- cabal install yi fails with dependency errors, e.g.:
$ cabal install yi
cabal.exe: dependencies conflict: ghc-6.8.3 requires bytestring ==0.9.0.1.1
bytestring-0.9.0.1.1 was excluded because bytestring-0.9.0.1 was selected
bytestring-0.9.0.1.1 was excluded because yi-0.3 requires bytestring =0.9.0.1
- Try removing all your old yi packages, and do
before attempting to install.
- cabal install -fghcAPI fails
- If you want GHC API special capabilities, you have to download, configure, build and copy separately:
cabal configure -fghcAPI
- Compilation fails with a message about alex not being available?
- Currently, Cabal doesn't track programs, just libraries, so it won't warn you if you are missing Alex (as many people are). The solution here is to just cabal install alex first. (Yi uses Alex to generate code for parsing stuff with syntax, like Haskell source.)
- I can't install yi-gtk or yi-vty! It wants sourceview or something.
- As the Hackage descriptions say, yi-gtk and yi-vty are only for versions of older than Yi 0.3. You really should be running the latest development (GitHub) or stable (Hackage) versions of Yi, so don't try to install these two packages. Yi supports VTY and Gtk2hs directly in the yi package now.
- On Mac OS X if you get an error message similar to this:
yi: can't load .so/.DLL for: gthread-2.0 (dlopen(libgthread-2.0.dylib, 10): image not found)
- then your dynamic library search path variable is probably not set correctly. You can set it (in Bash) using:
- (Adjust the specific path to your system. You can find the right location using locate libgthread)
- On Mac OS 10.6 (Snow Leopard) if you get the following error:
Loading package cairo-0.11.1 ... <command line>: can't load .so/.DLL for: pixman-1 (dlopen(/opt/local/lib/libpixman-1.dylib, 9): no suitable image found. Did find:
/opt/local/lib/libpixman-1.dylib: mach-o, but wrong architecture)
cabal: Error: some packages failed to install:
yi-0.6.2.4 failed during the building phase. The exception was:
- then the problem is that GHC currently only supports linking against i386 libraries, and your ports are compiled for x86_64. To fix, recompile your ports with the +universal variant like so:
port install installed +universal
- Compilation fails with errors about template-haskell or data-accessor:
Add constraints about which release of those libraries to use.
$ cabal install yi --constraint="data-accessor < 0.2.1" --constraint="template-haskell < 2.4"

- How do I install Yi for development?
- Fork the repository on GitHub, then clone your version to your machine. Push to your repo on GitHub, and then make merge requests.
- What are some of the dependancies?
- There is a rather long list of dependencies for Yi, check the yi.cabal file for a list.
- If you are on Mac OS X and are using MacPorts, then these will not be included in the GHC in that distribution. Many of the dependancies are in MacPorts (for example: ghc, ghc-devel, alex, and gtk2hs). However, you may have some trouble building with Cabal-1.5.2, since it is a development version of Cabal. To work around these issues, you might have to add the line "Build-Type: Simple" to the .cabal files in the above required packages.
How to Configure Yi
You can find configuration file examples in the 'examples/' directory, or online at http://code.haskell.org/yi/examples/.
You can find some user configs at https://github.com/yi-editor/yi/tree/master/yi-contrib/src/Yi/Config/Users
A good way to start is to copy yi.hs in your $XDG_CONFIG_HOME/yi directory (create it if needed), and hack as needed.
GError on startup
I get the error message "yi.exe: <<System.Glib.GError.GError>>" when I try to run yi.
Sometimes this is a result of yi not being able to find the contents of the art directory when trying to start in graphical mode (e.g. Gtk or Pango). Check that the install has be done correctly or use the VTY mode ($ yi -f vty).
For more detail on the error, modify main in Yi/Main.hs to catch GError:
Right finalCfg -> do catchGError (do
when (debugMode finalCfg) $ initDebug ".yi.dbg"
startEditor finalCfg state) (\(GError dom code msg) -> fail msg)
Note that more recent versions of Yi (e.g. from the GitHub repo) no longer simply display the anonymous GError but instead provide a more detailed error message (making the above code snippet unnecessary).
