This quick 5/10 minute reference aimed towards new users to Spacemacs specifically with Haskell. It’s also used for my own reference.
- Project - any directory with a git repository it seems
- Helm - the line dialog interface / plugin
- Intero - A emacs plugin for Haskell
- Haskell-mode - Another alternative emacs plugin for Haskell
File / Project navigation:
- Navigate to recently used file
SPC f r
- Navigate to recently used file in project
SPC p r
- Navigate to file (fuzzy search)
SPC p f
- Switch / select a project (fuzzy search)
SPC p p
- Show and navigate to file browser -
SPC f T
Search for text in all files in project (you need to enter at least 3 chars)
SPC / Search using word under cursor (just like the above
- Add type annotation to expression under cursor
SPC m h T
- Restart intero - (if you modified the cabal file, it’ll fix old config errors being reported)
SPC m i r
- Reformat code in current buffer
SPC m f
- Rename an identifier in the current file
SPC s e
- Go to definition (you may need to generate a TAGS file)
SPC m g g
- Auto format the buffer
SPC SPC hindent-reformat-buffer(requires hindent to be installed)
- Smaller windows / frames / views seem much more responsive. With that in mind, instead of using ‘internal’ splitting for windows I instead make a ‘frame’
SPC w F(essentially another window) which I can then handle more conveniently with a windows tiling manager.
- The default theme seems much more laggy than then alternatives
SPC T s.
- The little circle with a number in it (bottom left) is the window number. Press
Nin is the number to navigate to that window.
- If you find Emacs ‘frozen’ or busy working on some operation - I usually have a lot of luck cancelling any action with
C-G(control g), which is the default Emacs keybinding to cancel an operation (like
