- How can I just compile and run in one go without having to type "ghc --make main.hs" as arguments for the "compile..." command and then typing "main.exe" for "shell command..."? This is what you do all the time when using Visual Studio, Eclipse, etc: just hit the F5 key which builds all the dependencies and runs one or more generated executables. Easy. Visual Haskell does this (in the cases it does not hang for some unknown reason). Of course I could dig into ELISP, but somehow I feel this must be supported somehow.
Use C-c C-l to load the file into GHCi. This is better than just compiling it: you get an interactive environment in which to play around with, test out functions, etc. You can still 'run' your program by typing 'main' in GHCi.
- There seems to be support for "Haskell Font Lock Symbols", which should convert \, -> and maybe other symbols to good looking Unicode fonts. I can't get the correct fonts working on Windows. Now as I understood this is not really supported because of indentation problems, as underneed the single Unicode arrow character is converted into ->? This is unfortunate, because that's one of the things I really like about Sun's Fortress: the usage of Unicode symbols makes the text look much more mathematically, versus the half-century-old ASCII text. Furthermore in almost all Haskell books the richer font symbols are used for clarity. Any hints on this topic?
I wouldn't be surprised if this code had bit-rotted, or if there never has been Windows support. It's a corner function, used by few and therefore not that polished. By all means, try it out, and if it doesn't work, feel free to submit patches, but I doubt it'll get changed any time soon by a haskell-mode developer :) -- -David House, dmhouse@gmail.com
