-==============================================================================
- *haskellmode-overview*
-1. Overview ~
-
- The Haskell mode plugins provide advanced support for Haskell development
- using GHC/GHCi on Windows and Unix-like systems. The functionality is
- based on Haddock-generated library indices, on GHCi's interactive
- commands, or on simply activating (some of) Vim's built-in program editing
- support in Haskell-relevant fashion. These plugins live side-by-side with
- the pre-defined |syntax-highlighting| support for |haskell| sources, and
- any other Haskell-related plugins you might want to install (see
- |haskellmode-resources|).
-
- The Haskell mode plugins consist of three filetype plugins (haskell.vim,
- haskell_doc.vim, haskell_hpaste.vim), which by Vim's |filetype| detection
- mechanism will be auto-loaded whenever files with the extension '.hs' are
- opened, and one compiler plugin (ghc.vim) which you will need to load from
- your vimrc file (see |haskellmode-settings|).
-
-
- *haskellmode-requirements*
-1.1 Runtime Requirements ~
-
- The plugins require a recent installation of GHC/GHCi. The functionality
- derived from Haddock-generated library indices also requires a local
- installation of the Haddock documentation for GHC's libraries (if there is
- no documentation package for your system, you can download a tar-ball from
- haskell.org), as well as an HTML browser (see |haddock_browser|). If you
- want to use the experimental hpaste interface, you will also need Wget.
-
- * GHC/GHCi ~
- Provides core functionality. http://www.haskell.org/ghc
-
- * HTML library documentation files and indices generated by Haddock ~
- These usually come with your GHC installation, possibly as a separate
- package. If you cannot get them this way, you can download a tar-ball
- from http://www.haskell.org/ghc/docs/latest/
-
- * HTML browser with basic CSS support ~
- For browsing Haddock docs.
-
- * Wget ~
- For interfacing with http://hpaste.org.
-
- Wget is widely available for modern Unix-like operating systems. Several
- ports also exist for Windows, including:
-
- - Official GNU Wget (natively compiled for Win32)
- http://www.gnu.org/software/wget/#downloading
-
- - UnxUtils Wget (natively compiled for Win32, bundled with other ported
- Unix utilities)
- http://sourceforge.net/projects/unxutils/
-
- - Cygwin Wget (emulated POSIX in Win32, must be run under Cygwin)
- http://cygwin.com/packages/wget/

-==============================================================================
- *haskellmode-settings*
-2. Settings ~
-
- The plugins try to find their dependencies in standard locations, so if
- you're lucky, you will only need to set |compiler| to ghc, and configure
- the location of your favourite web browser. Given the variety of things to
- guess, however, some dependencies might not be found correctly, or the
- defaults might not be to your liking, in which case you can do some more
- fine tuning. All of this configuration should happen in your |vimrc|.
-
- *haskellmode-settings-main*
-2.1 GHC and web browser ~
-
- *compiler-ghc* *ghc-compiler*
- To use the features provided by the GHC |compiler| plugin, use the
- following |autocommand| in your vimrc:
->
- au BufEnter *.hs compiler ghc
-<
- *g:ghc*
- If the compiler plugin can't locate your GHC binary, or if you have
- several versions of GHC installed and have a preference as to which binary
- is used, set |g:ghc|:
->
- :let g:ghc="/usr/bin/ghc-6.6.1"
-<
-
- *:GHCStaticOptions*
-:GHCStaticOptions Edit the static GHC options for the current buffer.
- Useful for adding hidden packages (-package ghc).
-
- *g:haddock_browser*
- The preferred HTML browser for viewing Haddock documentation can be set as
- follows:
->
- :let g:haddock_browser="/usr/bin/firefox"
-<
-
- *haskellmode-settings-fine*
-2.2 Fine tuning - more configuration options ~
-
- Most of the fine tuning is likely to happen for the haskellmode_doc.vim
- plugin, so you can check the current settings for this plugin via the
- command |:DocSettings|. If all the settings reported there are to your
- liking, you probably won't need to do any fine tuning.
-
- *g:haddock_browser_callformat*
- By default, the web browser|g:haddock_browser| will be started
- asynchronously (in the background) on Windows or when vim is running in a
- GUI, and synchronously (in the foreground) otherwise. These settings seem
- to work fine if you are using a console mode browser (eg, when editing in
- a remote session), or if you are starting a GUI browser that will launch
- itself in the background. But if these settings do not work for you, you
- can change the default browser launching behavior.
-
- This is controlled by |g:haddock_browser_callformat|. It specifies a
- format string which uses two '%s' parameters, the first representing the
- path of the browser to launch, and the second is the documentation URL
- (minus the protocol specifier, i.e. file://) passed to it by the Haddock
- plugin. For instance, to launch a GUI browser on Unix-like systems and
- force it to the background (see also |shellredir|):
->
- :let g:haddock_browser_callformat = '%s file://%s '.printf(&shellredir,'/dev/null').' &'
-<
- *g:haddock_docdir*
- Your system's installed Haddock documentation for GHC and its libraries
- should be automatically detected. If the plugin can't locate them, you
- must point |g:haddock_docdir| to the path containing the master index.html
- file for the subdirectories 'libraries', 'Cabal', 'users_guide', etc.:
->
- :let g:haddock_docdir="/usr/local/share/doc/ghc/html/"
-<
- *g:haddock_indexfiledir*
- The information gathered from Haddock's index files will be stored in a
- file called 'haddock_index.vim' in a directory derived from the Haddock
- location, or in $HOME. To configure another directory for the index file,
- use:
->
- :let g:haddock_indexfiledir="~/.vim"
-<
- *g:wget*
- If you also want to try the experimental hpaste functionality, you might
- you need to set |g:wget| before the |hpaste| plugin is loaded (unless wget
- is in your PATH):
->
- :let g:wget="C:\Program Files\wget\wget.exe"
-<
-
- Finally, the mappings actually use|<LocalLeader>|behind the scenes, so if
- you have to, you can redefine|maplocalleader|to something other than '_'.
- Just remember that the docs still refer to mappings starting with '_', to
- avoid confusing the majority of users!-)
-
-==============================================================================
- *haskellmode-compiler* *ghc*
-3. GHC Compiler Integration ~
-
- The GHC |compiler| plugin sets the basic |errorformat| and |makeprg| to
- enable |quickfix| mode using GHCi, and provides functionality for show
- info (|_si|), show type (|_t| or mouse |balloon|), add type declaration
- (|_T|), create tag file (|_ct|), and insert-mode completion
- (|i_CTRL-X_CTRL-O|) based on GHCi browsing of the current and imported
- modules.
-
- To avoid frequent calls to GHCi, type information is cached in Vim. The
- cache will be populated the first time a command depends on it, and will
- be refreshed every time a |:make| goes through without generating errors
- (if the |:make| does not succeed, the old types will remain available in
- Vim). You can also unconditionally force reloading of type info using
- |:GHCReload| (if GHCi cannot load your file, the type info will be empty).
-
-
- In addition to the standard|quickfix| commands, the GHC compiler plugin
- provides:
-
- *:GHCReload*
-:GHCReload Reload modules and unconditionally refresh cache of
- type info. Usually, |:make| is prefered, as that will
- refresh the cache only if GHCi reports no errors, and
- show the errors otherwise.
-
- *:GHCi*
-:GHCi {command/expr} Run GHCi commands/expressions in the current module.
-
- *_ct*
-_ct Create |tags| file for the current Haskell source
- file. This uses GHCi's :ctags command, so it will work
- recursively, but will only list tags for exported
- entities.
-
- *_opt*
-_opt Shows a menu of frequently used GHC compiler options
- (selecting an entry adds the option as a pragma to the
- start of the file). Uses popup menu (GUI) or :emenu
- and command-line completion (CLI).
-
- *_lang*
-_lang Shows a menu of the LANGUAGE options supported by GHC
- (selecting an entry adds the language as a pragma to
- the start of the file). Uses popup menu (GUI) or
- :emenu and command-line completion (CLI).
-
- *_si*
-_si Show extended information for the name under the
- cursor. Uses GHCi's :info command.
-
- *_t*
-_t Show type for the name under the cursor. Uses cached
- info from GHCi's :browse command.
-
- *_T*
-_T Insert type declaration for the name under the cursor.
- Uses cached info from GHCi's :browse command.
-
- *haskellmode-XO* *haskellmode-omni-completion*
-CTRL-X CTRL-O Standard insert-mode omni-completion based on the
- cached type info from GHCi browsing current and
- imported modules. Only names from the current and from
- imported modules are included (the completion menu
- also show the type of each identifier).
-
-==============================================================================
- *haskellmode-haddock* *haddock*
-4. Haddock Integration ~
-
- Haskell mode integrates with Haddock-generated HTML documentation,
- providing features such as navigating to the Haddock entry for the
- identifier under the cursor (|_?|), completion for the identifier under
- the cursor (|i_CTRL-X_CTRL-U|), and adding import statements (|_i| |_im|
- |_iq| |_iqm|) or module qualifier (|_.|) for the identifier under the
- cursor.
-
- These commands operate on an internal Haddock index built from the
- platform's installed Haddock documentation for GHC's libraries. Since
- populating this index takes several seconds, it should be stored as a
- file called 'haddock_index.vim' in the directory specified by
- |g:haddock_indexfiledir|.
-
- Some commands present a different interface (popup menu or command-line
- completion) according to whether the current Vim instance is graphical or
- console-based (actually: whether or not the GUI is running). Such
- differences are marked below with the annotations (GUI) and (CLI),
- respectively.
-
- |:DocSettings| shows the settings for this plugin. If you are happy with
- them, you can call |:ExportDocIndex| to populate and write out the
- documentation index (should be called once for every new version of GHC).
-
- *:DocSettings*
-:DocSettings Show current Haddock-files-related plugin settings.
-
-
- *haskellmode-indexing*
-4.1 Indexing ~
-
- *:DocIndex*
-:DocIndex Populate the Haddock index from the GHC library
- documentation.
-
- *:ExportDocIndex*
-:ExportDocIndex Cache the current Haddock index to a file (populate
- index first, if empty).
-
-
- *haskellmode-lookup*
-4.2 Lookup ~
-
- *_?*
-_? Open the Haddock entry (in |haddock_browser|) for an
- identifier under the cursor, selecting full
- qualifications from a popup menu (GUI) or via
- command-line completion (CLI), if the identifier is
- not qualified.
-
- *:IDoc*
-:IDoc {identifier} Open the Haddock entry for the unqualified
- {identifier} in |haddock_browser|, suggesting possible
- full qualifications.
-
- *:MDoc*
-:MDoc {module} Open the Haddock entry for {module} in
- |haddock_browser| (with command-line completion for
- the fully qualified module name).
-
- *:FlagReference*
-:FlagReference {s} Browse Users Guide Flag Reference for section {s}
- (with command-line completion for section headers).
-
-
- *haskellmode-editing*
-4.3 Editing ~
-
- *_.*
-_. Fully qualify the unqualified name under the cursor
- selecting full qualifications from a popup menu (GUI)
- or via command-line completion (CLI).
-
- *_iq* *_i*
-_i _iq Add 'import [qualified] <module>(<identifier>)'
- statement for the identifier under the cursor,
- selecting fully qualified modules from a popup menu
- (GUI) or via command-line completion (CLI), if the
- identifier is not qualified. This currently adds one
- import statement per call instead of merging into
- existing import statements.
-
- *_iqm* *_im*
-_im Add 'import [qualified] <module>' statement for the
- identifier under the cursor, selecting fully qualified
- modules from a popup menu (GUI) or via command-line
- completion (CLI), if the identifier is not qualified.
- This currently adds one import statement per call
- instead of merging into existing import statements.
-
- *_ie*
-_ie On an 'import <module>' line, in a correctly loadable
- module, temporarily comment out import and use :make
- 'not in scope' errors to explicitly list imported
- identifiers.
-
- *haskellmode-XU* *haskellmode-user-completion*
-CTRL-X CTRL-U User-defined insert mode name completion based on all
- names known to the Haddock index, including package
- names. Completions are presented in a popup menu which
- also displays the fully qualified module from which
- each entry may be imported.
-
- CamelCode shortcuts are supported, meaning that
- lower-case letters can be elided, using only
- upper-case letters and module qualifier separators (.)
- for disambiguation:
-
- pSL -> putStrLn
- C.E.t -> Control.Exception.t
- C.M.MP -> Control.Monad.MonadPlus
-
- To reduce unwanted matches, the first letter of such
- shortcuts and the first letter after each '.' have to
- match directly.
-
-==============================================================================
- *haskellmode-hpaste* *hpaste*
-5. Hpaste Integration ~
-
- This experimental feature allows browsing and posting to
- http://hpaste.org, a Web-based pastebin tailored for Haskell code.
-
-
- *:HpasteIndex*
-:HpasteIndex Read the most recent entries from hpaste.org. Show an
- index of the entries in a new buffer, where ',r' will
- open the current highlighted entry and ',p' will
- annotate it with the current buffer.
-
- *:HpastePostNew*
-:HpastePostNew Submit current buffer as a new hpaste entry.
-
-==============================================================================
- *haskellmode-resources*
-6. Additional Resources ~
-
- An illustrated walk-through of these plugins is available at:
-
- http://www.cs.kent.ac.uk/people/staff/cr3/toolbox/haskell/Vim/vim.html
-
- Other Haskell-related Vim plugins can be found here:
-
- http://www.haskell.org/haskellwiki/Libraries_and_tools/Program_development#Vim
-
- Make sure to read about Vim's other program-editing features in its online
- |user-manual|. Also have a look at Vim tips and plugins at www.vim.org -
- two other plugins I tend to use when editing Haskell are AlignPlugin.vim
- (to line up regexps for definitions, keywords, comments, etc. in
- consecutive lines) and surround.vim (to surround text with quotes,
- brackets, parentheses, comments, etc.).
