Setup

Required (Before You Install SublimeHaskell)

You will need to install the GHC Haskell compiler, the cabal build tool and a backend before you install SublimeHaskell.

  • The Glorious Haskell Computer (ghc). Preferably, you should install the Haskell Platform if you don't already have a Haskell development and hacking environment set up.
  • cabal. Under normal circumstances, cabal should come pre-installed with your Haskell environment, e.g., if you installed the Haskell Platform.
  • A backend. SublimeHaskell communicates with the backend to support the interesting editing features. The preferred backend is hsdev. You can use one of the deprecated backends, but know that support for these backends may be dropped or removed in a future SublimeHaskell release.
    • hsdev cabal package (cabal install hsdev) for inspection, enhanced completion, goto, symbol info etc.
    • Deprecated backends
    • ghc-mod (for import and LANGUAGE completions and type inference, cabal install ghc-mod, not used if hsdev enabled, ghc-mod is used by hsdev as a library)

Install SublimeHaskell

  1. Get Sublime Text: http://www.sublimetext.com/
  2. Install the Sublime Package Control package: http://wbond.net/sublime_packages/package_control/installation
  3. Use Package Control to install SublimeHaskell

Open a Haskell source file, cabal builder file or a stack.yaml builder and have a productive Haskell development session!

Optional Tools

  • stack. The Haskell Tool Stack. If you installed the Haskell Platform, you already have this installed. stack is a companion Haskell build tool that supplements cabal.
  • SublimeREPL package for REPL support, if you want to interact with GHCI from within SublimeText.
  • Code prettifier:

Tool Installation Location

Tools (cabal, hsdev, ghc-mod, ghc, etc.) are usually installed in a directory that is already added to your PATH environment variable. SublimeHaskell will also look for these tools in several “Haskell standard” places. These places include:

Builder *nix Platforms Windows
stack $HOME/.local/bin %APPDATA%/local/bin
cabal user $HOME/.cabal/bin %APPDATA/cabal/bin
cabal global /usr/local/bin %PROGRAMFILES%/Haskell/bin

More advanced users can configure cabal's user and global install paths in $HOME/.cabal/config. SublimeHaskell will use these values if configured and if the directories to which they refer exist.

If you have a non-standard installation location for your tools, you can configure this in SublimeHaskell's “User Settings” by adjusting add_to_PATH. You will have to restart SublimeText after you save your preferences.

SublimeHaskell Theme

There is a special theme with enhanced Haskell entities and marks (errors, warnings and hints) coloring. Note different coloring for types and constructors (in import list, data declaration etc.), special coloring of generic variables in types, pragmas and module imports

Quickstart

  • Open the SublimeText Command Palette ( Ctrl-Shift-P or Option-Command-P on OS X) and type haskell to explore SublimeHaskell's goodness.

  • When editing Haskell source files, automatic error highlighting and enhanced auto-completion is available.

  • Each time you save, any errors in your program will be listed at the bottom of the window and highlighted in the source code.

  • All source files in the project are scanned on change. Any symbols that they export are provided in the auto-complete suggestions.

  • Stylish-haskell can be used to stylish file or selected text.

  • Use F12 to go to declaration and ctrl+k ctrl+i to show symbol info with documentation. These commands are also available through context menu with right-click.

  • To show inferred types use Show type (ctrl-k ctrl-h ctrl-t) command.

  • To insert inferred type use Insert type (ctrl-k ctrl-h ctrl-i).

  • You can jump between the errors and warnings with alt+d alt+e and alt+shift+d alt+shift+e.

  • To show hidden error output, use command Show error panel (ctrl-alt-e)

Features and SublimeHaskell Goodness

Stack support

Build commands such as Build, Clean, Install, Rebuild uses stack if there is stack.yaml near .cabal. If you don't want to use stack, set haskell_build_tool setting to cabal.

hsdev uses stack to build dependencies and to get corresponding package-dbs. Since 0.1.7.2 it passes --compiler and --arch options to stack to get package-dbs built with hsdev-compatible compiler.

Enhanced completion

Works in export list (showing symbols in scope), import list, expressions. Completes after module qualifier (several modules can be import qualified as with same qualifier). Takes into account module reexports for sources. Autocompletion

Popups

  • Show popup with symbol info and with error/warning/hint details. Requires SublimeText 3 dev build > 3116 (https://forum.sublimetext.com/t/dev-build-3116/21148). Hover

  • It also shows inferred type when possible HoverTypes

  • And you can autofix warnings/hints on popup for warnings/hints AutoFixHover

  • SublimeHaskell: Toggle symbol info panel — toggle continuout symbol info panel, which show info about symbol under cursor. Useful when reading code. SymbolInfo

Inside and outside your project: codex

codex allows you to use ctags to jump to definitions that are declared in your cabal dependencies.

  • cabal install codex
  • Run codex set format sublime, that updates your ~/.codex file to Sublime's Ctags plugin's format
  • Change ~/.codex to tagsFileName: .tags
  • In your project, codex cache clean && codex update
  • You can now jump to the source code of definitions outside of your project.
  • The commands CTags: Show Symbols and CTags: Rebuild Tags currently don't work with codex
