Revision history for skylighting and skylighting-core

0.14.3

  • Add crystal, racket, zip syntax (#194).

0.14.2

  • Add loadValidSyntaxesFromDir (Kevin Quick) [API change]. The loadSyntaxesFromDir function is an all-or-nothing function: a single invalid file results in a error and no loaded syntaxes. This adds the loadValidSyntaxesFromDir, which is resilient against individual syntax file load failures. It returns a map of the failure messages, and the SyntaxMap that is created from all the successful parsing.

0.14.1.2

  • Add terraform syntax (#190).

0.14.1.1

  • Add GPRBuild syntax.

  • Update syntax descriptions for clojure, cmake, coffee, cpp, cs, erlang, graphql, haskell, javascript, julia, kotlin, lilypond, markdown, objectivec, objectivecpp, ocaml, perl, python, ruby, rust, stan, typescript, yaml.

0.14.1

  • Update syntax definitions for julia, actionscript, bash, cpp, css, djangotemplate, dosbat, groovy, html, ini, isocpp, java, javadoc, json, jsp, latex, makefile, mustache, php, powershell, rest, rhtml, sass, scala, scss, toml, xml, raku (with patch).

  • Many improvements to regular expression compilation:

    • Properly recognize unicode characters.
    • Handle \Q..\E literal sequences.
    • Handle group modifiers like (?i:etc.). (The only one we actually pay attention to is i.)
    • Allow unicode category escapes outside of character classes.
    • Support one-letter unicode category escapes like \p{L}. These are found in some of the newer syntax definitions.

  • Improve regex matching:

    • Fix wordDetect to work around an issue in the new html.xml.
    • Refactor and fix atWordBoundary: remove redundant checks, and fix behavior (/x\b/ was behaving like /\bx\b/) (Côme ALLART).
    • Fix bug in lastCharOffset (Côme ALLART).

  • Style: Allow colors to be specified in ARGB format (#178). We currently just ignore the A part, but at least we don't fail.

0.14

  • Add rWeakDeliminators field to Rule. [API change]

  • Make WordDetect sensitive to weakDeliminator. This fixes parsing of floats beginning with '0.' in C (#174).

  • Add debiancontrol syntax (#173).

0.13.4.1

  • Update syntax definitions: ada, bash, cmake, css, html, isocpp, java, javascript, kotlin, latex, makefile, markdown, php, python, qml, r, sass, scss, typescript, zsh.

  • Don't require word boundary at end of Int, Float, HlCHex, HlCOct (#170). KDE does not. This fixes things like 7L in R.

0.13.4

  • Add dosbat syntax (MS DOS batch file) (#169).

  • Derive Bounded Instance for TokenType (#168, Pavan Pikhi). Add Bounded to the derived instances for the TokenType type. This allows consumers to use [minBound .. maxBound] to generate a list of all token types when writing a Style.

  • Require xml-conduit >= 1.9.1.3. This fixes a bug that prevents parsing certain DOCTYPE declarations, e.g. in agda.xml.

  • Updated cmake syntax definition.

0.13.3

  • Add gap language (#167).

  • Update syntax definitions.

  • Add patches for agda.xml and dtd.xml, to wor around a bug in xml-conduit: snoyberg/xml#187

  • Store compiled regexes in RE (#166, Jonathan Coates). This changes the RE type to (lazily) compile the regex when constructed, rather than in the tokenizer. This allows us to avoid re-compiling regexes for each separate tokenize call, instead sharing them globally. We try to hide the internals of this, exposing the previous interface (RE { reString, reCaseSensitive }) with pattern synonyms.

  • ConTeXt: fix handling of spaces in non-normal tokens (Albert Krewinkel). This ensures that multiple spaces won't be collapsed into a single space.

0.13.2.1

  • Update tango style for new token types (#164). The original tango style didn't have colors defined for many token types that have been added since it was added. This commit updates the style to support them. Thanks to @danbraswell for providing the values needed.

0.13.2

  • Support ConTeXt output via skylighting-format-context (Albert Krewinkel).

  • Update syntax definitions for markdown, nim, javascript.

0.13.1.2

  • Update syntax definitions for c, cmake, commonmlisp, css, go, ini, isocpp, javascript, json, powershell, python, rust, sass, scss, toml, xml.

  • Associate regex captures with a context. This is necessary for proper implementation of the KDE syntax highlighting algorithm. Captures are only available within the context to which the match creating the capture switches. (Closes #160.)

0.13.1.1

  • Add dart, purescript syntax definitions.

  • Update syntax definitions for isocpp, latex, alert, bash, cmake, nix, sql-postgresql, vhdl, zsh.

  • Remove obsoleote patch for lua.xml.

  • Add patches for latex.xml and isocpp.xml.

0.13.1

  • getCapture: fail instead of throwing error if dynamic match not found. I believe this is the intended behavior for StringDetect, judging from examples in the KDE documentation.

  • Update xml syntax definitions: asn1, bash, c, cmake, cpp, cs, d, elixir, fortran-fixed, gcc, glsl, go, html, java, javascript, lex, lua, markdown, mediawiki, noweb, ocaml, orgmode, php, powershell, prolog, python, r, ruby, rust, scheme, sql-postgresql, typescript, vhdl, xml, yacc, yaml, zsh

  • Replace a lambda with pointfree notation (shaving off some RAM usage) (0xd34df00d).

  • Use newtype for TokenizerM, giving about 5-10% boost on benchmark (0xd34df00d).

0.13

  • Update syntax definitions from upstream: bash, cmake, diff, ini, perl, php, sgml, xml.

  • Split out formatters into separate packages (#152). API changes:

    • Skylighting.Core no longer exports Skylighting.Format.ANSI, Skylighting.Format.HTML, Skylighting.Format.LaTeX. These are now provided by separate packages, skylighting-format-ansi, skylighting-format-blaze-html, skylighting-format-latex.
    • Skylighting.Types no longer exports XTerm256ColorCode. This has been moved to skylighting-format-ansi.

  • Change Makefile to use cabal instead of stack.

0.12.3.1

  • Allow mtl 2.3.

  • Update syntax defs from upstream: bash, cmake, go, haxe, lua, zsh.

  • Add nix.xml (#149).

  • Add Pygments styles for Import and BuiltIn token types (#147, Bryan A. Danielak).

  • Use StrictData.

  • Remove unused dependencies (silences cabal warnings) (Andreas Abel).

0.12.3

  • Add scss, sass, systemverilog, orgmode.

  • Update xml definitions from upstream: bash, css, python, r, zsh.

0.12.2

  • Parser: handle context shift to external context, e.g., BashOneLine##Bash. Closes #139 (issue with Dockerfile).

  • Update xml files from upstream: bash, cmake, markdown, objectivecpp, php, sql-postgresql, sql, stan, zshr

  • Fix formatting in Color doc-comment (Janek Spaderna).

  • Add stan.xml (Brian Ward).

0.12.1

  • Update syntax definitions: bash, cmake, dockerfile, gnuassembler, markdown, spdx-comments.

  • Support hex escapes using \x in regex char classes (#135). These occur in a number of syntax definitions and weren't correctly interpreted before. Thanks to @Agnishom.

  • Support regex property syntax, e.g. \p{Lu}.

  • Regex: support \B (non-word-boundary).

0.12

  • Properly handle include elements in keyword lists (#124). A number of syntaxes (e.g. typescript, scala) include keyword lists from other syntaxe,s and previously we weren't able to handle this.

    There are several pieces to this change. We need to store lists where other Syntaxes can look them up, so we add an sLists field to Syntax [API change], and modify the parser to fill this. We change lists so that their values are not just a Text, but a ListItem that can either be a textual value or an include directive, specifying a ListName (syntax name and list name).

    The Keyword constructor for Matcher now takes, instead of a WordSet, Either a ListName or a WordSet (API change).

    Skylighting.Parser now exports resolveKeywords (API change), which modifies all Keyword matchers in a syntax so that Left values with a ListName become Right values with resolved WordSets. The tokenizer applies this function automatically to the SyntaxMap given in Config. But it is more efficient to do this conversion just once, rather than every time tokenize is called. So we have loadSyntaxesFromDir call it on the SyntaxMap. With this optimization, there is not an appreciable performance cost to the changes described above.

  • Skylighting.Regex: Fix bug with regexes like a{10}b (#133). This requires exactly 10 a's; previously we interpreted it as "at least 10."

  • skylighting-extract: take a directory as argument rather than files. This allows us to use loadSyntaxesFromDir.

  • Update xml syntax definitions from upstream: julia, cmake, cpp, isocpp, markdown, python, toml.

0.11

  • Skylighting.Regex: Support regex subroutines (#118). For example, (?1) is replaced by the regex in the first capturing group. So far we only support this simple, absolute form, not the relative form (?-1) supported by some engines (but not used, I think, in KDE's syntax highlighters). This change involves an API change: Regex in Skylighting.Regex has a new Subroutine constructor, and the Recurse constructor has been removed. Instead of Recurse we use Subroutine 0, which unifies the code.

  • Skylighting.Regex: handle e.g. [\1] and [\123] (without initial 0) as octal escapes (#118). These occur in the zsh.xml syntax definition.

  • Pull xml definitions for bash, cmake, python, zsh from upstream.

  • README: Add a note about pulling syntax definitions from upstream (#138). Update build instructions for recent cabal versions (#131).

0.10.5.2

  • Added swift grammar definition (Igor Ranieri).

  • Simplify README.md instructions for two-step build.

  • Fix link to KDE documentation.

0.10.5.1

  • Regex: Allow lookaheads to capture groups. Previously captures in lookaheads, like (?=(a*)), were ignored. This led to errors highlighting xml and probably other formats (#121).

  • Throw an exception if a capture group isn't defined (with 'dynamic') rather than simply having getCapture fail so that the rule fails. This will make it easier to debug issues like #121.

0.10.5

  • Fix regression from 0.10.3 with Haskell highlighting of Char (#120).

  • Update xml syntax definitions from upstream. Updated syntaxes: abc apache asp bash bibtex boo c changelog clojure cmake commonlisp cs curry d diff djangotemplate doxygen elixir elm email erlang fortran-fixed fortran-free fsharp hamlet haskell haxe html idris ini javascript-react javascript json julia kotlin latex lex lilypond literate-curry literate-haskell makefile markdown mathematica maxima mediawiki metafont modula-2 mustache nasm nim noweb ocaml octave opencl perl powershell prolog pure python r roff ruby rust sed spdx-comments sql-mysql sql-postgresql tcl tcsh toml typescript verilog xml xslt xul yacc yaml. Not updated: rhtml (causes an error on our test suite), zsh (has a regex we can't parse).

0.10.4.1

  • Fixed logic for checking line-end-context (#119).

  • Use NonEmpty for the context stack.

  • Remove unneeded build-depends.

0.10.4

  • Move from hxt to xml-conduit for XML parsing.

    This gives about a 4X speedup in parsing syntax definitions. It also reduces the pandoc build dependency footprint, as we depend on xml-conduit anyway and now no longer need to compile HXT and its dependencies.

    There are improvements in accuracy as well: the change to xml-conduit improved parsing for one of the prolog rules; a matcher that should have been for tab characters had been set for a space instead.

  • Removed some unnecessary build-depends in skylighting-extract.

0.10.3

  • Add support for raku (#114).

  • Reimplement PR #40 and add haskell.xml.patch (#116).

  • Update syntax definitions: actionscript ada asp awk bash bibtex boo c cmake cpp cs d elm email fasm fsharp glsl gnuassembler go haskell haskell idris isocpp javascript julia latex lilypond makefile mediawiki metafont mustache objectivec objectivecpp octave opencl perl php php powershell prolog purebasic raku rest ruby sed spdx-comments sql-mysql sql-postgresql sql typescript verilog vhdl.

  • Fix php.xml.patch so it applies again.

0.10.2

  • Update syntax definitions for abc, actionscript, asn1, ats, bash, boo, coffee, comments, cpp, cs, css, curry, d, djangotemplate, dockerfile, doxygen, dtd, elixir, graphql, groovy, hamlet, haskell, haxe, idris, ini, j, java, javadoc, javascript-react, javascript, jsp, kotlin, lex, lilypond, literate-curry, literate-haskell, m4, makefile, mandoc, markdown, mediawiki, mips, modula-2, modula-3, monobasic, mustache, nim, noweb, objectivec, objectivecpp, ocaml, opencl, pascal, perl, php, pike, postscript, prolog, protobuf, pure, purebasic, python, qml, relaxng, relaxngcompact, rest, rhtml, roff, ruby, scala, sci, sed, sgml, sml, spdx-comments, stata, tcsh, texinfo, verilog, xml, xorg, xul.

  • Re-insert CSS line needed to make line numbers appear in HTML. See jgm/pandoc#6625.

0.10.1

  • Regex: handle (?|) modifier. This is used in bash.xml now. It resets the numbers of capturing groups in alternatives.

  • Improve regex handling of { and } not in quantifiers:

    • {} is literal (not a quantifier).
    • loose unescaped { and } that are not part of a quantifier are literal matchers.

  • Update xml syntax definitions from upstream. For: abc, actionscript, ada, agda, alert, apache, asn1, asp, ats, awk, bash, boo, c, clojure, cmake, coffee, coldfusion, commonlisp, cs, css, curry, d, djangotemplate, dockerfile, dot, doxygen, dtd, eiffel, elixir, elm, erlang, fasm, fortran-fixed, fortran-free, fsharp, glsl, gnuassembler, go, graphql, groovy, hamlet, haskell, haxe, html, idris, ini, isocpp, j, java, javadoc, javascript, jsp, julia, kotlin, latex, lex, lilypond, literate-curry, literate-haskell, llvm, lua, m4, makefile, markdown, mathematica, matlab, maxima, mediawiki, metafont, mips, modula-2, modula-3, monobasic, mustache, nasm, nim, noweb, objectivec, objectivecpp, ocaml, octave, opencl, pascal, perl, php, pike, postscript, povray, powershell, prolog, protobuf, pure, purebasic, python, r, relaxng, relaxngcompact, rest, rhtml, roff, ruby, rust, scala, scheme, sci, sed, sgml, sml, sql-mysql, sql-postgresql, sql, stata, tcl, tcsh, texinfo, toml, verilog, vhdl, xml, xorg, xslt, xul, yacc, yaml, zsh. Also added spdx-comments.xml and comments.xml, which are needed for these. Closes #111 (latex bug in matrix).

0.10.0.3

  • Add groovy syntax.

0.10.0.2

  • Improve DetectIdentifier to ensure that identifiers can't include non-ASCII characters.

0.10.0.1

  • Fix identifier detection in non-ASCII context (#110).

0.10

  • Add instructions for submitting patches upstream to KDE (#106).

  • Synced syntax definitions from KDE repo. Note that fortran has split into two: fortran-fixed and fortran-free.

  • Add test to ensure that all regexes in rules compile.

  • Regex: allow unescaped }.

  • Regex: allow empty regexes and groups.

  • Regex: support lazy and possessive quantifiers (#109).

  • Regex: support recursive regexes (?R) (#108).

  • Hide invisible line numbers from keyboard focus (#107, d10n). This fixes tabbing through elements on a page.

  • Remove some obsolete patches for xml definitions.

0.9

  • Use a pure Haskell regex implementation (in unexported module Text.Regex.KDE) instead of pcre. The implementation is not as efficient as pcre, but it seems good enough for this application, and it is desirable to avoid depending on a C library. (Available Haskell libraries weren't up to the task, because they don't do back-references, captures, lookahead/behind.) Some benchmarks (old/new): haskell (4.6/7.9) java (13.4/23.3) c (2.8/3.7) rhtml (4.7/6.1) lua (10.6/13.2) javascript (4.2/6.6). Though this is a significant slowdown, the tradeoff seems worth it to have a pure Haskell implementation.

  • Removed old system-pcre flag.

  • More efficient treatment of dynamic regexes. We put something in the Regex itself to represent the %1, and modify it later. This allows us to cache dynamic regexes in a way we couldn't before.

  • Add support for TOML (#105, Shiming Wang), GraphQL, and Nim syntax (#102, Daniel Pozo Escalona).

  • Update xml definitions for actionscript, bash, boo, c, cmake, elm, erlang, glsl, isocpp, java, lua, m4, mediawiki, perl, powershell, scala, tcsh, xul, zsh.

  • Fix fallthrough behavior (don't always consume a token).

  • Fix word boundary detection.

  • Remove RegexException. (API change)

  • Skylighting.Regex now exports isWordChar and testRegex, as well as the constructors underlying the new Regex type.

  • Remove some obsolete xml definition patches.

  • Fix escaped % in dynamic regex.

0.8.5

  • Respect dynamic flag on StringDetect elements (#99, Albert Krewinkel).

  • Increase test timeout to avoid failures with qemu-emulated environments, such as qemu and riscv64 in Ubuntu builders (William Grant).

  • Fix attribute for opening double quote in sql-postgresql.xml (Benjamin Wuethrich).

  • Update syntax descriptions for javascript, bash, coffee, javascript-react, javascript, latex, sql-postgresql, typescript.

0.8.4

  • HTML output: use aria-hidden="true" on empty a elements unless numberLines is specified (in which case the element is still empty but will have content added by CSS). This is to avoid excess noise when the code blocks are read by screen readers. See jgm/pandoc#6352.

0.8.3.4

  • Update syntax descriptions for: cmake agda c coffee doxygenlua html isocpp latex lua makefile markdown metafont mustache nasm python rust sql-postgresql typescript vhdl xml yacc yaml.

  • Fix invalid CSS: in some cases, the library produced code span. with no class for the NormalTok style (Michał Miszczyszyn). Now it produces a rule for code span.

0.8.3.3

  • Agda keywords updated to 2.6.0 (Andreas Abel).

0.8.3.2 -- 2020-01-21

  • This fixes a packaging error in 0.8.3.1, which didn't include the results of the bootsrap step and hence didn't update the syntax modules.

0.8.3.1 -- 2020-01-21

  • Escape < and > in latex to avoid ligatures (#91).

  • Fix and extend Idris keywords (Denis Buzdalov).

  • Update XML syntax definitions for javascript-react, qml, typescript, javascript, cmake, cofee, latex, perl, python, rest.

  • Fixed bug with context shifts using ## syntax for foreign context. Previously we only handled these in IncludeRules, but starting with the current batches of xml files they can occur elsewhere too.

0.8.3 -- 2019-11-26

  • Update XML syntax definitions for c, cmake, coffee, cpp, css, diff, djangotemplate, elixir, elm, glsl, haskell, html, isocpp, javascript-react, javascript, json, jsp, julia, latex, lua, markdown, matlab, mediawiki, modelines, mustache, perl, php, powershell, qml, rest, rust, typescript, vhdl.

  • Fix highlighting errors with non-ASCII characters in JSON (#90). This error was due to an optimization that made some incorrect assumptions.

0.8.2.3 -- 2019-10-03

  • Tests: ensure we read test files as UTF-8.

  • Fix compiler warnings around Monoid imports.

  • Add MonadFail constraint (allowing compilation with ghc 8.8.x).

  • Add cabal.project and move CI from Travis to GitHub Actions.

0.8.2.2 -- 2019-09-30

  • Remove upper bound on regex-base and require regex-pcre-builtin >= 0.95, to avoid a build conflict with earlier versions of regex-pcre-builtin and regex-base >= 0.94.

  • Remove unused system-pcre flag in skylighting.cabal. This flag only affects skylighting-core.

0.8.2.1 -- 2019-09-25

  • Add upper bound for regex-base if regex-pcre-builtin is used. Currently regex-pcre-builtin won't build on ghc 8.4+ with regex-base 0.94.0.0. When regex-pcre-builtin is updated, we can remove this.

  • Correct cabal wildcard to include .xml.patch files in distribution.

  • Update breezedark style (Kien Dang).

  • Update markdown.xml so first list marker is included in list (#84).

  • skylighting.cabal - removed some build dependencies which are not necessary (they're dependencies of skylighting-core).

0.8.2 -- 2019-07-14

  • Change matchRegex so it gives "no match" on a regex error instead of raising an exception. This seems to be how Kate works. Fixes an error on long integer literals (#81).

0.8.1.2 -- 2019-07-14

  • Fix HlCChar for one-character octal escapes like '\0' (#82). Due to a bug in pCStringChar, only multi-character octal escapes were being recognized. This affects not just C highlighting, but all of the following highlighters which use HlCChar: fasm eiffel pike objectivec ruby vhdl scala java jsp nasm protobuf pure go objectivecpp gnuassembler povray actionscript c cs opencl boo rhtml elixir. This fixes a regression introduced in version 0.3.1.
  • Ensure line span css only applied to lines (David Baynard).

0.8.1.1 -- 2019-06-13

  • Improved LaTeX escaping (#78).

0.8.1 -- 2019-06-04

  • Added support for stata (#74).
  • Added support for javascript-react, i.e. jsx (#56).
  • Added support for qml and mustache (new dependencies for markdown and html).
  • Update xml syntax definitions from KDE repository: cmake, doxygen, html, ini, javascript, julia, literate-haskell, markdown, octave, perl, tcsh, typescript, yaml.
  • Fix bug in detectIdentifier (#76). It behaved wrongly when applied to a string that was an valid identifier but had nothing else after it (as would naturally occur with inline code in pandoc). The bug caused it to match just one character in this case.
  • Add --number-lines-from option to cli program (David Baynard).
  • Override start number if nonzero (David Baynard, fixes regression in 0.8).

0.8 -- 2019-05-27

  • Wrap html source lines with <span>, not <a> (David Baynard). Fixes jgm/pandoc#4386. Also fixes #33 (and therefore fixes jgm/pandoc#4278).
  • Prevent line-wrap overlap in html by increasing padding (David Baynard).
  • Remove superfluous 'pointer-events: all' (David Baynard).
  • Simplify HTML generation code (David Baynard).
  • Remove sourceLine class from spans (David Baynard).
  • Display line numbers using css counters (David Baynard).
  • Add Elm syntax definition (#66, #68, Bonghyun Kim).
  • Put changelog in base directory, use symlinks to point to it. We have the same changelog for skylighting and skylighting-core, for simplicity. (Version numbers are kept in sync.)

0.7.7 -- 2019-02-27

  • Add parseSyntaxDefinitionFromString [API change].
  • Fix parseSyntaxDefinition so that language.dtd no longer needed. We strip out the SYSTEM "language.dtd" part of the doctype if present, leaving any inline entity definitions. This applies to both parseSyntaxDefinition and parseSyntaxDefinitionFromString.
  • Revised documentation of bootstrap build.
  • Makefile - fix bootstrap target.
  • Use FilePath instead of String for path (#64, anchpop).

0.7.6 -- 2019-02-08

  • Update xml definitions for C, CPP, D, Haskell, Maxima, PHP, Ruby, Typescript.
  • Fix regex problem in erlang.xml (#63).
  • Export WordSet constructors (#62, Chris Martin).
  • Add support for protobuf (#60).

0.7.5 -- 2018-12-01

  • Updated definitions for cmake, lua, prolog, rust, yacc, javascript.
  • Added definition for sml (#53).
  • Added definition for J (#50).
  • Added definition for typescript (#57).
  • Fix comments preceded by multiple spaces in bash.xml (#54).
  • Add *.txt extension and text/plain mime type to default.xml (#48).
  • Add file:/// if we have a Windows path with a drive. Otherwise HXT will take it to be a URI. See jgm/pandoc#4836.

0.7.4 -- 2018-10-08

  • HTML output: use title instead of data-line-number. data- attributes are not valid HTML 4, and we would like this to work with HTML 4 (e.g. in epub v2). See jgm/pandoc#4920.
  • Print FALLTHROUGH in --trace output.
  • Updated syntax definitions for actionscript, awk, bash, c, clojure, cmake, coffee, cs, css, dockerfile, email, fortran, gcc, haskell, ini, isocpp, java, javadoc, javascript, jsp, kotlin, latex, lua, mediawiki, modelines, modula-2, objectivec, objectivecpp, opencl, perl, powershell, prolog, python, r, rest, rhtml, ruby, rust, scala, sql-mysql, sql-postgresql, sql, tcl, vhdl, xml, xul, yaml, zsh.

0.7.3 -- 2018-08-27

  • Add 'default.xml' to syntax descriptions.
  • Raise base lower bounds to 4.8. Drop support for ghc 7.8.
  • Use absolute number for cabal version, as now required.

0.7.2 -- 2018-06-08

  • Update syntax definitions from upstream.
  • Added support for POV-Ray syntax (#46).
  • Display line numbers without absolute positioning (David Baynard, #32).

0.7.1 -- 2018-03-15

  • Fix benchmarks, which previously depended on a module defined in skylighting (#42).
  • Export Skylighting.Loader from Skylighting.Core.
  • Bump version bound for criterion.

0.7.0.2 -- 2018-03-06

  • Ensure that regex captures are not overwritten by regexes without captures.
  • Fixed bug in subDynamic (#41).
  • Added tracing information about rules tried and dynamic regexes, for debugging.
  • Fix highlighting for Haskell chars which breaks -XDataKinds (#40, Artyom Kazak).

0.7.0.1 -- 2018-03-03

  • Updated changelog.md.

0.7 -- 2018-03-03

  • Split skylighting into skylighting-core (BSD3) and skylighting (GPL) (#37, Jonathan Daugherty). skylighting-core (BSD3 licensed) includes the core library functionality and the source of the XML syntax, but not the compiled Syntax modules, and skylighting (GPL2 licensed) includes Syntax modules compiled from the XML syntax files.

  • We discontinue support for GHC before 7.10 (because we need to support the reexport-modules Cabal directive.)

  • Print message about loaded syntax defs to stderr (#36).

  • New module Skylighting.Loader, exporting loadSyntaxFromFile and loadSyntaxesFromDir (Jonathan Daugherty).

  • Adjust tests to load xml definitions dynamically.

0.6 -- 2018-01-18

  • Add ANSI color output (Alexander Ronald Altman, #22).

    • New package dependencies: ansi-terminal and colour.
    • New module: Skylighting.Format.ANSI, exporting formatANSI, (also reexported from the module Skylighting).
    • In Skylighting.Types, new types ANSIColorLevel and Xterm256ColorCode, and a new field ansiColorLevel in FormatOptions.
    • Main skylighting executable now supports ANSI output (use ansi as argument to --format), which is now the default output format. A new flag --color-level has been added to select the number of colors (with options 16, 256, true, and the default auto).

  • Reword error for missing contexts in IncludeRules.

  • Use ordNub instead of nub for missingIncludes.

0.5.1 -- 2018-01-07

  • Fixed tokenizer exceptions (#31). Previously throwError did not actually generate Left results in tokenize, because of the way the MonadPlus instance worked. Rewrote the TokenizerM monad from scratch so that exceptions would not be skipped.

  • Improved error message about undefined contexts.

  • Makefile: use cabal for bootstrap target.

  • README: remove stack bootstrap instructions. You can no longer bootstrap with stack, because it insists on building ALL the executables the first time, and of course that can't be done with this library.

  • Use quickcheck for fuzz test.

0.5.0.1 -- 2017-12-18

  • Small improvements to fuzz tests in test suite. We now ensure that we print the random text on test failure. Also, we now run the test with many smaller samples rather than one big one.

  • Add aeson lower bound (because of toEncoding) (#28).

0.5 -- 2017-12-10

  • Fix line spacing and overflowing content in generated HTML (David Baynard, #25, see jgm/pandoc#4128).

    • Fix empty line height, explicitly
    • Ensure long lines scroll on screen
    • Only apply colour to the outer div
    • Don't reset line number colour
    • Fix borders on empty code lines
    • Collapse divs correctly.

  • Changes to Style types and JSON instances. Previously we could not successfully round-trip through JSON.

    • tokenStyles is now a map rather than an association list.
    • We now use line-number-color instead of line-numbers at the top level in the JSON instances, falling back to line-numbers in editor-colors, for KDE theme compatibility.
    • We use line-number-background-color at the top level, falling back to the text background color.
    • We use text-color at the top level, falling back to the text-color of the Normal token style if it exists, for KDE compatibility.
    • We use background-color at the top level, falling back to the background-color in editor-colors, for KDE compatibility.
    • A round-trip JSON test has been added.

0.4.4.1 -- 2017-11-27

  • HTML formatting: fix color, bgcolor when numbering enabled. Previously, the code got the color and background color the numbers were supposed to get. See jgm/pandoc #4103.
  • Updated syntax descriptions for bash, clojure, commonlisp, diff, dockerfile, doxygen, doxygenlua, fsharp, hamlet, haskell, haxe, java, javascript, julia, latex, literate-curry, literate-haskell, makefile, mediawiki, monobasic, ocaml, prolog, r, relaxng, scala, sci, sql-mysql, sql-postgresql, sql, xslt.
  • test program: use --accept instead of --regen.

0.4.4 -- 2017-11-21

  • HTML formatter: always use an a element (rather than a div) for source lines. The divs were invalid, because code elements must contain phrasing content. Previously we used a elements when line anchors were called for, but there is no clear reason not to use them always.
  • skylighting binary: add doctype to generated HTML.

0.4.3.2 -- 2017-11-04

  • Fixed regression in data-line-number attributes in HTML output. We should not include the lineIdPrefix in front of this.

0.4.3.1 -- 2017-11-03

  • Fixed typo in css (Artymort).
  • Fixed travis build times.

0.4.3 --- 2017-11-02

  • FormatOptions: added lineIdPrefix (jgm/pandoc#4031). This is needed because a web page may contain several code samples, and we need to make sure that the ids on lines are unique.
  • HTML formatter: use lineIdPrefix in ids for lines.
  • HTML formatter: Don't put href attributes on divs.

0.4.2 --- 2017-10-26

  • HTML output: remove outer div. This prevented margin collapsing between the pre and surrounding block elements, and often gave us excess white space around code blocks. See jgm/pandoc#3996.

0.4.1 --- 2017-09-28

  • Updated XML definitions from KDE repository. Changed: actionscript, ada, agda, alert, alert_indent, asn1, awk, bash, boo, c, changelog, clojure, cmake, coldfusion, commonlisp, cpp, cs, css, curry, d, dockerfile, dot, doxygen, doxygenlua, eiffel, email, erlang, fortran, fsharp, gcc, haskell, haxe, isocpp, java, javascript, jsp, julia, lilypond, lua, m4, makefile, matlab, maxima, mips, modelines, modula-2, monobasic, objectivec, objectivecpp, ocaml, octave, opencl, pascal, perl, php, pike, postscript, prolog, purebasic, python, r, relaxng, relaxngcompact, rest, rhtml, ruby, rust, scala, scheme, sci, sql-mysql, sql-postgresql, sql, tcl, tcsh, verilog, vhdl, xml, xslt, xul, zsh.
  • Added support for powershell, using definition from KDE repository.
  • Stop terminating long builds on TravisCI (Kyle Ondy).

0.4 --- 2017-09-15

  • Removed ToJSON/FromJSON instances for KeywordAttr, WordSet, Matcher, Context, ContextSwitch, Rule, Syntax (added in 0.3.5). Creating these increased the memory requirements for compiling skylighting to a degree not justified by the usefulness of these instances.

0.3.5 --- 2017-09-14

  • Added ToJSON/FromJSON instances for all basic types.
  • Added some background colors to 'kate' style, matching default.theme, and made FromJSON for Style sensitive to background-color.

0.3.4.1 -- 2017-09-09

  • HTML formatting: do not use div elements for source lines in inline output.

0.3.4 -- 2017-09-09

  • HTML formatting changes (David Baynard). Note that these changes may require changes in hard-coded CSS that is used with skylighting's HTML output.

    • Wrap lines of source code in a div with display set to inline-block. The divs make per-line processing easier. They cannot be set as display: block as that introduces extra new lines when copying and pasting.
    • Render line numbers in html using CSS pseudo elements rather than a table. The line numbers are always produced, as data-line-number attributes, and css to display them as ::before elements are always produced. The option to switch on line numbering only toggles a class; this means it is possible to toggle line numbering without re-running skylighting.
    • If the linkAnchors option is set, wrap with an a element rather than a div, set so that clicking the line number (and only the line number) will jump to that line.
    • Code wraps by default when html is printed, with wrapped lines indented.

0.3.3.1 -- 2017-06-26

  • Updated xml syntax definitions and clojure test.
  • Improved 'make update-xml' target.
  • Updated version bound for criterion.

0.3.3 -- 2017-04-22

  • Revert change from 0.3.2; now entities from a DTD are resolved if the DTD element is included. This is needed for agda.xml and some others. If you want to use a custom xml definition without needing language.dtd, just remove the reference to language.dtd in your xml file.
  • Added case keyword for ats (Hanwen (Steinway) Wu).

0.3.2 -- 2017-04-01

  • Parse xml definitions without resolving entities from language.dtd. This allows xml definitions to be used even when language.dtd isn't available. Existing definitions don't rely on the two or three entities definied in language.dtd, so this is harmless.
  • Small optimizations.

0.3.1 -- 2017-02-28

  • Use handwritten parser for Float instead of regex. Fixes jgm/highlighting-kate#57 (again).
  • Added float parsing tests.
  • Use parsec parsers, not regex, for CStringChar and CChar.
  • Rewrote Int, Hex, Oct, CStringChar, CCHar parsers with parsec instead of regex. This speeds things up.
  • Don't include leading + in Int, Hex, Oct parsers. That gives bad results for things like i+1.

0.3 -- 2017-02-19

  • Store literal binary-encoded representations of the Syntax structure in Skylighting.Syntax.*.hs, instead of the structure itself. This works around a problem ghc has compiling modules with large structures. This indirect method produces faster compile times and avoids massive memory usage by ghc (especially in profiling builds). For background see http://stackoverflow.com/questions/16348340/. Closes #7.
  • Types: Internals of 'WordSet' are no longer exposed.

0.2 -- 2017-02-19

  • Restore Data, Typeable, Generic instances for basic types. To do this, we remove reCompiled field from RE (API change). Instead, we have the tokenizer compile regexes the first time it encounters them, memoizing the results. Performance is not significantly worse.
  • Skylighting.Syntax.*: use string representation of the Syntax, which is then 'read', rather than including the code for the data structure directly (#7). This indirect method produces faster compile times and avoids massive memory usage by ghc (especially in profiling builds). For background see http://stackoverflow.com/questions/16348340/compiling-very-large-constants-with-ghc
  • Use -fprof-auto-exported for profiling builds.
  • Added benchmark for xml syntax definition parsing.
  • Patched perl.xml (improperly escaped regex) (#8). This fixes a perl regex compilation error for regex patterns with backslash as delimiter, e.g. m\a.
  • Add a flag to build with system pcre (Felix Yan).

0.1.1.5 -- 2017-02-03

  • Avoid depending on a PrintfArg instance for Text (#5). This isn't provided in some older versions of the text library. This change should allow the package to build on older platforms.

0.1.1.4 -- 2017-01-31

  • Properly escape characters in subDynamic. This fixes a problem that caused failures with

    echo -e "s\0b\0c" | skylighting -s perl

  • More efficient rewrite of char escaping for regexes.

0.1.1.3 -- 2017-01-29

  • Increase test timeout to 6s.
  • Avoid double {{}} in latex macros.
  • Fixed problem compiling Format.LaTeX on older ghc versions (7.8.3) that can't take a Text as PrintfArg.

0.1.1.2 -- 2017-01-28

  • Added much more extensive testing to ensure that tokenizers don't hang or drop input.
  • Fixed some issues with line-end and fallthrough context handling.
  • Fixed a bug in WordDetect handling which caused it to drop input (#2).

0.1.1.1 -- 2017-01-21

  • Optimized. Speed is now comparable to highlighting-kate and often better.
  • Added benchmarks.

0.1.1 -- 2017-01-19

  • Added breezeDark style, from breeze-dark.theme.
  • Fixed performance bug in regex application (#1). This gives a significant speedup, especially for inputs with long lines.

0.1.0.1 -- 2016-12-23

  • Fixed bug in LaTeX renderer (backslash in wrong position).

0.1.0.0 -- 2016-12-23

  • Initial release
