" Vim syntax file " Language: Haskell Cabal Build file " Author: Vincent Berthoux <twinside@gmail.com> " Maintainer: Marcin Szamotulski <profunctor@pm.me> " Previous Maintainer: Vincent Berthoux <twinside@gmail.com> " File Types: .cabal " Last Change: 15 May 2018 " v1.5: Incorporated changes from " https://github.com/sdiehl/haskell-vim-proto/blob/master/vim/syntax/cabal.vim " Use `syn keyword` instead of `syn match`. " Added cabalStatementRegion to limit matches of keywords, which fixes " the highlighting of description's value. " Added cabalVersionRegion to limit the scope of cabalVersionOperator " and cabalVersion matches. " Added cabalLanguage keyword. " Added calbalTitle, cabalAuthor and cabalMaintainer syntax groups. " Added ! and ^>= operators (calbal 2.0) " Added build-type keywords " v1.4: Add benchmark support, thanks to Simon Meier " v1.3: Updated to the last version of cabal " Added more highlighting for cabal function, true/false " and version number. Also added missing comment highlighting. " Cabal known compiler are highlighted too. " " V1.2: Added cpp-options which was missing. Feature implemented " by GHC, found with a GHC warning, but undocumented. " Whatever... " " v1.1: Fixed operator problems and added ftdetect file " (thanks to Sebastian Schwarz) " " v1.0: Cabal syntax in vimball format " (thanks to Magnus Therning) " quit when a syntax file was already loaded if exists("b:current_syntax") finish endif " this file uses line continuation let s:cpo_save = &cpo set cpo&vim " set iskeyword for this syntax script syn iskeyword @,48-57,192-255,- " Case sensitive matches syn case match syn keyword cabalConditional if else syn keyword cabalFunction os arche impl flag syn match cabalComment /--.*$/ " Case insensitive matches syn case ignore syn keyword cabalCategory contained \ executable \ library \ benchmark \ test-suite \ source-repository \ flag \ custom-setup syn match cabalCategoryTitle contained /[^{]*\ze{\?/ syn match cabalCategoryRegion \ contains=cabalCategory,cabalCategoryTitle \ nextgroup=cabalCategory skipwhite \ /^\c\s*\(contained\|executable\|library\|benchmark\|test-suite\|source-repository\|flag\|custom-setup\)\+\s*\%(.*$\|$\)/ syn keyword cabalTruth true false " cabalStatementRegion which limits the scope of cabalStatement keywords, this " way they are not highlighted in description. syn region cabalStatementRegion start=+^\s*\(--\)\@<!\k\+\s*:+ end=+:+ syn keyword cabalStatement contained containedin=cabalStatementRegion \ default-language \ default-extensions \ author \ branch \ bug-reports \ build-depends \ build-tools \ build-type \ buildable \ c-sources \ cabal-version \ category \ cc-options \ copyright \ cpp-options \ data-dir \ data-files \ default \ description \ executable \ exposed-modules \ exposed \ extensions \ extra-tmp-files \ extra-doc-files \ extra-lib-dirs \ extra-libraries \ extra-source-files \ exta-tmp-files \ for example \ frameworks \ ghc-options \ ghc-prof-options \ ghc-shared-options \ homepage \ hs-source-dirs \ hugs-options \ include-dirs \ includes \ install-includes \ ld-options \ license \ license-file \ location \ main-is \ maintainer \ manual \ module \ name \ nhc98-options \ other-extensions \ other-modules \ package-url \ pkgconfig-depends \ setup-depends \ stability \ subdir \ synopsis \ tag \ tested-with \ type \ version \ virtual-modules " operators and version operators syn match cabalOperator /&&\|||\|!/ syn match cabalVersionOperator contained \ /!\|==\|\^\?>=\|<=\|<\|>/ " match version: `[%]\@<!` is to exclude `%20` in http addresses. syn match cabalVersion contained \ /[%$_-]\@<!\<\d\+\%(\.\d\+\)*\%(\.\*\)\?\>/ " cabalVersionRegion which limits the scope of cabalVersion pattern. syn match cabalVersionRegionA \ contains=cabalVersionOperator,cabalVersion \ keepend \ /\%(==\|\^\?>=\|<=\|<\|>\)\s*\d\+\%(\.\d\+\)*\%(\.\*\)\?\>/ " version inside `version: ...` syn match cabalVersionRegionB \ contains=cabalStatementRegion,cabalVersionOperator,cabalVersion \ /^\s*\%(cabal-\)\?version\s*:.*$/ syn keyword cabalLanguage Haskell98 Haskell2010 " title region syn match cabalName contained /:\@<=.*/ syn match cabalNameRegion \ contains=cabalStatementRegion,cabalName \ nextgroup=cabalStatementRegion \ oneline \ /^\c\s*name\s*:.*$/ " author region syn match cabalAuthor contained /:\@<=.*/ syn match cabalAuthorRegion \ contains=cabalStatementRegion,cabalStatement,cabalAuthor \ nextgroup=cabalStatementRegion \ oneline \ /^\c\s*author\s*:.*$/ " maintainer region syn match cabalMaintainer contained /:\@<=.*/ syn match cabalMaintainerRegion \ contains=cabalStatementRegion,cabalStatement,cabalMaintainer \ nextgroup=cabalStatementRegion \ oneline \ /^\c\s*maintainer\s*:.*$/ " license region syn match cabalLicense contained /:\@<=.*/ syn match cabalLicenseRegion \ contains=cabalStatementRegion,cabalStatement,cabalLicense \ nextgroup=cabalStatementRegion \ oneline \ /^\c\s*license\s*:.*$/ " license-file region syn match cabalLicenseFile contained /:\@<=.*/ syn match cabalLicenseFileRegion \ contains=cabalStatementRegion,cabalStatement,cabalLicenseFile \ nextgroup=cabalStatementRegion \ oneline \ /^\c\s*license-file\s*:.*$/ " tested-with region with compilers and versions syn keyword cabalCompiler contained ghc nhc yhc hugs hbc helium jhc lhc syn match cabalTestedWithRegion \ contains=cabalStatementRegion,cabalStatement,cabalCompiler,cabalVersionRegionA \ nextgroup=cabalStatementRegion \ oneline \ /^\c\s*tested-with\s*:.*$/ " build type keywords syn keyword cabalBuildType contained \ simple custom configure syn match cabalBuildTypeRegion \ contains=cabalStatementRegion,cabalStatement,cabalBuildType \ nextgroup=cabalStatementRegion \ /^\c\s*build-type\s*:.*$/ " Define the default highlighting.
