- How do I install Yi?
- get it from Hackage. Configure, compile and install Yi as you would do for any other Cabal package.
- 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, eg:
$ cabal install yi Resolving dependencies... cabal.exe: dependencies conflict: ghc-6.8.3 requires bytestring ==0.9.0.1.1 however bytestring-0.9.0.1.1 was excluded because bytestring-0.9.0.1 was selected instead 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:
cd yi cabal configure -fghcAPI cabal build cabal copy
- 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)
- How do I install Yi for development?
- Get it from http://code.haskell.org/yi while there are other repositories of Yi out there, this is the latest.
- What are some of the dependancies?
- The development version of Yi currently requires Cabal-1.4, fingertree-0.0, and utf8-string-0.3.1.
- 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.
2.1 How to Configure Yi
You can find configuration file examples in the 'examples/' directory, or online at http://code.haskell.org/yi/examples/.
A good way to start is to copy yi.hs in your ~/.yi directory (create it if needed), and hack as needed.
