パッケージ: hdevtools (0.1.6.1-1)

GHC powered daemon for fast Haskell development

hdevtools is a backend for text editor plugins, to allow for things such as syntax and type checking of Haskell code, and retrieving type information, all directly from within your text editor.

The advantage that hdevtools has over ghc-mod is that it runs silently in a persistent background process, and therefore is able to keeps all of your Haskell modules and dependent libraries loaded in memory. This way, when you change only a single source file, only it needs to be reloaded and rechecked, instead of having to reload everything.

This makes hdevtools very fast for checking syntax and type errors (runs just as fast as the ":reload" command in GHCi).

In fact, syntax and type checking is so fast, that you can safely enable auto checking on every save. Even for huge projects, checking is nearly instant.

In addition to checking Haskell source code for errors, `hdevtools` has tools for getting info about identifiers, and getting type information for snippets of code.
