                                                    *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*

                                                    *haskellmode-settings*
  1. 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_browser_nosilent*

If you find that on your system opening the documentation browser corrupts
the vim display, you can choose to not exec the browser silently. This
often fixes the display but means you have to press a key to continue
after opening the browser.

    :let g:haddock_browser_nosilent = 1

<

                                                        *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
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"

<

Another experimental functionality is caching the symbol information to a
background file. If you are importing big modules such as OpenGL, loading
the symbol information from GHCi by |:GHCReload| can take really long time. 
To shorten the time it takes to browse the symbols you can enable caching of
the symbol data to a background file every time |:GHCReload| is called. When 
browsing for a symbol, if the symbol table is empty and cached file is 
available, it is used to populate the symbol table. To enable the symbol 
cache set the following variable to 1:
    :let g:ghc_symbolcache=1

<

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*
  1. 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

    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 (more generally, options

                    that cannot be set by in-file OPTIONS_GHC pragmas)
                    for the current buffer. Useful for adding hidden 
                    packages (-package ghc), or additional import paths
                    (-isrc; you will then also want to augment |path|).
                    If you have static options you want to set as
                    defaults, you could use b:ghc_staticoptions, eg:
                    au FileType haskell let b:ghc_staticoptions = '-isrc'
                    au FileType haskell setlocal path += src

<

                                                                   *: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*
  1. 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*

                    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*

_?2 Search Hayoo! (using |haddock_browser|) for an

                    identifier under the cursor.

                                                                   *:IDoc*

                    {identifier} in |haddock_browser|, suggesting possible
                    full qualifications.

                                                                   *:MDoc*

                    |haddock_browser| (with command-line completion for
                    the fully qualified module name).

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.

  1. 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]

  1. 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.).
