Additional Resources |haskellmode-resources| - -============================================================================== - *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 - matching your GHC version from http://www.haskell.org/ghc/docs/ - - * 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-quickref* -1.2 Quick Reference ~ - -|:make| load into GHCi, show errors (|quickfix| |:copen|) -|_ct| create |tags| file -|_si| show info for id under cursor -|_t| show type for id under cursor -|_T| insert type declaration for id under cursor -|balloon| show type for id under mouse pointer -|_?| browse Haddock entry for id under cursor -|_?1| search Hoogle for id under cursor -|_?2| search Hayoo! for id under cursor -|:IDoc| {identifier} browse Haddock entry for unqualified {identifier} -|:MDoc| {module} browse Haddock entry for {module} -|:FlagReference| {s} browse Users Guide Flag Reference for section {s} -|_.| qualify unqualified id under cursor -|_i| add 'import <module>(<identifier>)' for id under cursor -|_im| add 'import <module>' for id under cursor -|_iq| add 'import qualified <module>(<identifier>)' for id under cursor -|_iqm| add 'import qualified <module>' for id under cursor -|_ie| make imports explit for import statement under cursor -|_opt| add OPTIONS_GHC pragma -|_lang| add LANGUAGE pragma -|i_CTRL-X_CTRL-O| insert-mode completion based on imported ids (|haskellmode-XO|) -|i_CTRL-X_CTRL-U| insert-mode completion based on documented ids (|haskellmode-XU|) -|i_CTRL-N| insert-mode completion based on imported sources -|:GHCi|{command/expr} run GHCi command/expr in current module - -|:GHCStaticOptions| edit static GHC options for this buffer -|:DocSettings| show current Haddock-files-related plugin settings -|:DocIndex| populate Haddock index -|:ExportDocIndex| cache current Haddock index to a file -|:HpasteIndex| Read index of most recent entries from hpaste.org -|:HpastePostNew| Submit current buffer as a new hpaste - - -============================================================================== - *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. You will also want to make - sure that |filetype| detection and |syntax| highlighting are on. 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|. -> - " enable syntax highlighting - syntax on - - " enable filetype detection and plugin loading - filetype plugin on -< - - *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" -< - *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. - - *:GHCStaticOptions* -:GHCStaticOptions Edit the static GHC options for the current buffer. - Useful for adding hidden packages (-package ghc). - - *: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. Output appears in - |preview-window| (when done, close with |:pclose|). - - *_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. - - *_?1* -_?1 Search Hoogle (using |haddock_browser|) for an - identifier under the cursor. - - - *_?2* -_?2 Search Hayoo! (using |haddock_browser|) for an - identifier under the cursor. - - *: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. - [This, and ',p' above, are temporarily disabled, - needs update to new hpaste.org layout] - -============================================================================== - *haskellmode-resources* -6. Additional Resources ~ - - An quick screencast tour through of these plugins is available at: - - http://projects.haskell.org/haskellmode-vim/screencasts.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.). - -============================================================================== - vim:tw=78:ts=8:ft=help: |
