SPELL CHECK

by Ingo Karkat

DESCRIPTION

Vim offers built-in spell checking; when you enable it via 'spell' and 'spelllang', you can jump to the highlighted spelling errors in the buffer via ]s. With spelling errors scattered across a large document, Vim does not provide an overview or report about the overall spell situation.

This plugin populates the |quickfix|-list with all spelling errors found in a buffer to give you that overview. You can use the built-in quickfix features to navigate to the first occurrence of a particular spell error. You can also manage the spelling errors (mark as good / bad word, globally replace with suggestion) directly from the quickfix window via the usual zg, zw, z= etc. mappings.

A typical workflow (e.g. when composing email, commit messages, or any form of documentation) includes writing and/or quitting the buffer, unless some remaining spelling errors require further intervention. This plugin offers auxiliary enhanced variants of :bdelete, :write and :quit that check for spelling errors and only execute the action if none were found. So by using these replacement commands, you'll never send or commit messages full of embarrassing typos any more!

USAGE

:[range]SpellCheck[!] [bad | rare | local | caps] [...] [{predicates}]
                        Show all / the passed type(s) of spelling errors as a
                        quickfix list [at locations where {predicates} yield
                        true] SpellCheck-predicates.
                        For multiple occurrences of the same error, the first
                        location and the number of occurrences is shown.
                        If [!] is not given the first error is jumped to.

                        In the quickfix list, spelling errors from other
                        buffers are kept, so you can use something like
                            :argdo SpellCheck
                        to gather the spelling errors from multiple buffers.

:[range]SpellLCheck[!] [bad | rare | local | caps] [...] [{predicates}]
                        Same as :SpellCheck, except the location list for the
                        current window is used instead of the quickfix list.

You can pass arbitrary Vimscript expressions that then need to match at the
current spell error location to consider the spelling error; else, that
particular error will be ignored. For example, the following will ignore spell
errors in a Vim modeline:
    :SpellCheck getline('.') !~ 'vim:'
If you define the following syntactic sugar function (in your vimrc)
    function! Syntax( pattern )
        return ingo#syntaxitem#IsOnSyntax(getpos('.'), a:pattern)
    endfunction
you can easily limit spell checking to certain syntax elements, e.g. to
exclude spell errors inside comments:
    :SpellCheck !Syntax('Comment')

MAPPINGS

                        Inside the quickfix window, the following mappings are
                        remapped so that they operate on the target spell
                        error: zg, zG, zw, zW, zug, zuG, zuw,
                        zuW, z=, u
                        For z=, all identical misspellings in the buffer are
                        replaced with the chosen suggestion (via
                        :spellrepall).
                        You can also quickly undo the last spell suggestion
                        from the quickfix window (i.e. without switching to
                        the target buffer) via u.
                        For the other commands, the taken action is appended
                        to the quickfix list entry, so that the list serves as
                        a record of done actions (until you refresh the list
                        with a new :SpellCheck).

AUXILIARY COMMANDS

The following set of commands just issue an error when spelling errors exist
in the buffer or passed [range] of lines.

:BDeleteUnlessSpellError[!] [bad | rare | local | caps] [...] [{predicates}]
                                :bdelete| the current buffer, unless it
                                contains spelling errors.
:WriteUnlessSpellError[!] [bad | rare | local | caps] [...] [{predicates}]
                                :write the current buffer, unless it
                                contains spelling errors.
:WriteDeleteUnlessSpellError[!]  [bad | rare | local | caps] [...] [{predicates}]
                                :write and :bdelete the current buffer,
                                unless it contains spelling errors.
:XitUnlessSpellError[!] [bad | rare | local | caps] [...] [{predicates}]
                                :write  the current buffer and :quit,
                                unless it contains spelling errors.

:NextUnlessSpellError[!] [bad | rare | local | caps] [...] [{predicates}]
                                Edit :next file, unless the current buffer
                                contains spelling errors.

This set of commands automatically opens the quickfix list in case of spelling
error in the buffer or passed [range] of lines.

:BDeleteOrSpellCheck[!] [bad | rare | local | caps] [...] [{predicates}]
                                :bdelete the current buffer, or show the
                                spelling errors in the quickfix list.
:WriteOrSpellCheck[!] [bad | rare | local | caps] [...] [{predicates}]
                                :write the current buffer, or show the
                                spelling errors in the quickfix list.
:WriteDeleteOrSpellCheck[!] [bad | rare | local | caps] [...] [{predicates}]
                                :write and :bdelete the current buffer,
                                or show the spelling errors in the quickfix
                                list.
:XitOrSpellCheck[!] [bad | rare | local | caps] [...] [{predicates}]
                                :write the current buffer and :quit, or
                                show the spelling errors in the quickfix list.

:NextOrSpellCheck[!] [bad | rare | local | caps] [...] [{predicates}]
                                Edit :next file, or show the current
                                buffer's spelling errors in the quickfix list.

:UpdateAndSpellCheck[!] [bad | rare | local | caps] [...] [{predicates}]
                                :update the current buffer, and show any
                                spelling errors in the quickfix list.

                                A [!] is passed to the :write / :bdelete /
                                :quit commands.

INSTALLATION

The code is hosted in a Git repo at https://github.com/inkarkat/vim-SpellCheck You can use your favorite plugin manager, or "git clone" into a directory used for Vim packages. Releases are on the "stable" branch, the latest unstable development snapshot on "master".

This script is also packaged as a vimball. If you have the "gunzip" decompressor in your PATH, simply edit the *.vmb.gz package in Vim; otherwise, decompress the archive first, e.g. using WinZip. Inside Vim, install by sourcing the vimball or via the :UseVimball command.

vim SpellCheck*.vmb.gz
:so %

To uninstall, use the :RmVimball command.

DEPENDENCIES

• Requires Vim 7.0 or higher.
• Requires the ingo-library.vim plugin (vimscript #4433), version 1.024 or higher.
• repeat.vim (vimscript #2136) plugin (optional)
• visualrepeat.vim (vimscript #3848) plugin (optional)

CONFIGURATION

For a permanent configuration, put the following commands into your vimrc:

If you don't want the auxiliary commands, just the core :SpellCheck command, use:

let g:SpellCheck_DefineAuxiliaryCommands = 0

If you just want some of the auxiliary commands, or under different names, or similar commands, you can easily define them yourself, as the core spell check functionality is available as global autoload functions. Have a look at plugin/SpellCheck.vim for inspiration.

If you don't want the SpellCheck-mappings that allow you to manage the spell errors directly from the quickfix window, use:

let g:SpellCheck_DefineQuickfixMappings = 0

The :SpellCheck command captures not just the misspelled word, but also some text around it, to provide context in the quickfix list. The number of occurrences of a particular spell error is set at:

let g:SpellCheck_ErrorContextNum = 99

You can tweak that, reduce it to 1 to only show the first, or 0 to completely turn off context.

What text around the current spell error gets captured can be tweaked via a regular expression that contains a %s parameter, which is replaced with the atom for the spell error start position. As Vim uses a special, spellfile-dependent definition of word characters, these can be tweaked separately.

The plugin can provide additional syntax highlighting for the quickfix window when it contains spell errors; to turn this off, use:

let g:SpellCheck_QuickfixHighlight = 0

To ignore some (e.g. rare) spell errors from the checks, you can define a List of considered types; these are overwritten by any [bad | rare | local | caps] argument(s) given to individual commands:

let g:SpellCheck_ConsideredErrorTypes = ['bad', 'local', 'caps']

Likewise, you can specify default predicates that limit the accepted spell errors unless any predicates are passed to the individual command:

let g:SpellCheck_Predicates = 'getline(".") !~ "^#"'

To change the highlighting colors, redefine (after any :colorscheme command) or link the two highlight groups:

highlight link qfSpellErrorWord             SpellBad
highlight link qfSpellErrorWordInContext    Normal
highlight link qfSpellContext               SpecialKey

INTEGRATION

By default, 'spell' will be automatically enabled when it's off, but you must have already set 'spelllang' for a functioning spell check. If you have written a custom auto-detection for the languages that you frequently use, you can integrate this here through a Funcref. The custom function must take no arguments, and set 'spell' and 'spelllang' accordingly.

let g:SpellCheck_OnNospell = function('SpellCheck#AutoEnableSpell')

If you want :SpellCheck to fail when 'spell' is off:

let g:SpellCheck_OnNospell = ''

All commands that manipulate the word lists are executed through a Funcref; by default, it automatically enables 'spell', like g:SpellCheck_OnNospell.

HISTORY

2.01 RELEASEME

• BUG: [count] of quickfix mappings gets clobbered by :normal.
• ENH: Employ optional repeat.vim / visualrepeat.vim plugins to allow repeat of quickfix mappings with . command from within the quickfix window.
• Skip spell checking in the quickfix window / location list window itself.

2.00 06-Oct-2017

• ENH: Make all commands take optional [bad | rare | local | caps] type argument (the forwarded [++opt] [file] accepted by some auxiliary commands probably aren't very important here) and use that for limiting the checks to those spell error types.
• ENH: Make all commands take optional predicates that limit the checked locations, e.g. to text within a certain syntax group only.
• Introduce g:SpellCheck_ConsideredErrorTypes configuration variable to limit the error types by default.
• Go to the first misspelling in the passed range (if any) instead of the first overall. I think this is more DWIM.
• Set the quickfix type to the capitalized first letter of the spell error type, except for the default "bad" ones. This allows for better differentiation than the previous lumping of rare + local as warning vs. errors.

You need to update to ingo-library (vimscript #4433) version 1.024!

1.30 24-Jul-2014

• ENH: Show words surrounding the spell error. The number of captured occurrences is controlled by g:SpellCheck_ErrorContextNum, what gets captured by g:SpellCheck_ErrorContextPattern. Thanks to Enno Nagel for the suggestion.
• ENH: Add syntax highlighting for the misspelled word, the error context text, and occurrences of the misspelled word inside the context. Enno Nagel also suggested this.
• FIX: Quickfix mappings are gone when closing and reopening the quickfix window (:cclose | copen), because a new scratch buffer is used, but the autocmd BufRead quickfix has been cleared.

1.21 23-Sep-2013

• Add :NextUnlessSpellError and :NextOrSpellCheck auxiliary commands.
• Allow to pass optional [++opt] [file] arguments to the :Write... commands.
• Add dependency to ingo-library (vimscript #4433).

You need to separately install ingo-library (vimscript #4433) version 1.001 (or higher)!

1.20 08-May-2012

• FIX: Line range is not defined and passed for :BDeleteOrSpellCheck and other :...OrSpellCheck commands, resulting in a script error.
• ENH: Allow [range] for :BDeleteUnlessSpellError and other :...UnlessSpellError commands, too.

1.13 02-May-2012

• ENH: In the quickfix list, apply undo via u to the target buffer to allow a quick revert of a spell correction.

1.12 01-May-2012

• ENH: Allow spell checking of partial buffers by allowing [range] for :SpellCheck command.

1.11 30-Apr-2012

• ENH: Capture corrected text and include in quickfix status message.

1.10 30-Apr-2012

• ENH: Allow to manage the spelling errors (mark as good / bad word, globally replace with suggestion) directly from the quickfix window via the usual zg, zw, z= etc. mappings.

1.01 14-Dec-2011

• ENH: Allow accumulating spelling errors from multiple buffers (e.g. via :argdo SpellCheck).

1.00 06-Dec-2011

• First published version.

0.01 02-Dec-2011

• Started development.
