Rust core team member!)
TypeScript updated with annotations and param lists inside constructors, by
Raphael Parree.
CoffeeScript updated with new keywords and fixed to recognize JavaScript
in ```, thanks to thanks to Geoffrey Booth.
Compiler directives in Delphi are now correctly highlighted as “meta”.
Version 9.8.0 “New York”
This version is the second one that deserved a name. Because I’m in New York,
and the release isn’t missing the deadline only because it’s still Tuesday on
West Coast.
Recognize struct as a class-level definition in Rust
Recognize b-prefixed chars and strings in Rust
Better numbers handling in Verilog
Version 9.0.0
The new major version brings a reworked styling system. Highlight.js now defines
a limited set of highlightable classes giving a consistent result across all the
styles and languages. You can read a more detailed explanation and background in
the tracking issue that started this long process back in May.
This change is backwards incompatible for those who uses highlight.js with a
custom stylesheet. The new style guide explains how to write styles
in this new world.
Bundled themes have also suffered a significant amount of improvements and may
look different in places, but all the things now consistent and make more sense.
Among others, the Default style has got a refresh and will probably be tweaked
some more in next releases. Please do give your feedback in our
issue tracker.
Notable fixes and improvements to existing languages:
ES6 features in JavaScript are better supported now by Gu Yiling.
Swift now recognizes body-less method definitions.
Single expression functions def foo, do: ... now work in Elixir.
More uniform detection of built-in classes in Objective C.
Fixes for number literals and processor directives in Rust.
HTML <script> tag now allows any language, not just JavaScript.
Multi-line comments are supported now in MatLab.
Version 8.4
We’ve got the new demo page! The obvious new feature is the new look, but
apart from that it’s got smarter: by presenting languages in groups it avoids
running 10000 highlighting attempts after first load which was slowing it down
and giving bad overall impression. It is now also being generated from test
code snippets so the authors of new languages don’t have to update both tests
and the demo page with the same thing.
Other notable changes:
The template_comment class is gone in favor of the more general comment.
Number parsing unified and improved across languages.
C++, Java and C# now use unified grammar to highlight titles in
function/method definitions.
The browser build is now usable as an AMD module, there’s no separate build
target for that anymore.
We streamlined our tool chain, it is now based entirely on node.js instead of
being a mix of node.js, Python and Java. The build script options and arguments
remained the same, and we’ve noted all the changes in the documentation.
Apart from reducing complexity, the new build script is also faster from not
having to start Java machine repeatedly. The credits for the work go to Jeremy
Hull.
Some notable fixes:
PHP and JavaScript mixed in HTML now live happily with each other.
JavaScript regexes now understand ES6 flags “u” and “y”.
throw keyword is no longer detected as a method name in Java.
We’ve finally got real tests and continuous testing on Travis
thanks to Jeremy Hull and Chris Eidhof. The tests designed to cover
everything: language detection, correct parsing of individual language features
and various special cases. This is a very important change that gives us
confidence in extending language definitions and refactoring library core.
We’re going to redesign the old demo/test suite into an interactive
demo web app. If you’re confident front-end developer or designer and want to
help us with it, drop a comment into the issue on GitHub.
As usually there’s a handful of new languages in this release:
Lisp variants (Lisp, Clojure and Scheme) are unified in regard to naming
the first symbol in parentheses: it’s “keyword” in general case and also
“built_in” for built-in functions in Clojure and Scheme.
The shorter lang- prefix for language names in HTML classes supported
alongside language-. Thanks to Jeff Escalante.
Ruby’s got support for interactive console sessions. Thanks to
Pascal Hurni.
Added built-in functions for R language. Thanks to Artem A. Klevtsov.
Rust’s got definition for lifetime parameters and improved string syntax.
Thanks to Roman Shmatov.
Various improvements to Objective-C definition by Matt Diephouse.
Fixed highlighting of generics in Java.
Version 8.0
This new major release is quite a big overhaul bringing both new features and
some backwards incompatible changes. However, chances are that the majority of
users won’t be affected by the latter: the basic scenario described in the
README is left intact.
Here’s what did change in an incompatible way:
We’re now prefixing all classes located in CSS classes reference with
hljs-, by default, because some class names would collide with other
people’s stylesheets. If you were using an older version, you might still want
the previous behavior, but still want to upgrade. To suppress this new
behavior, you would initialize like so:
tabReplace and useBR that were used in different places are also unified
into the global options object and are to be set using configure(options).
This function is documented in our API docs. Also note that these
parameters are gone from highlightBlock and fixMarkup which are now also
rely on configure.
We removed public-facing (though undocumented) object hljs.LANGUAGES which
was used to register languages with the library in favor of two new methods:
registerLanguage and getLanguage. Both are documented in our API docs.
Result returned from highlight and highlightAuto no longer contains two
separate attributes contributing to relevance score, relevance and
keyword_count. They are now unified in relevance.
Another technically compatible change that nonetheless might need attention:
The structure of the NPM package was refactored, so if you had installed it
locally, you’ll have to update your paths. The usual require('highlight.js')
works as before. This is contributed by Dmitry Smolin.
New features:
Languages now can be recognized by multiple names like “js” for JavaScript or
“html” for, well, HTML (which earlier insisted on calling it “xml”). These
aliases can be specified in the class attribute of the code container in your
HTML as well as in various API calls. For now there are only a few very common
aliases but we’ll expand it in the future. All of them are listed in the
class reference.
Language detection can now be restricted to a subset of languages relevant in
a given context — a web page or even a single highlighting call. This is
especially useful for node.js build that includes all the known languages.
Another example is a StackOverflow-style site where users specify languages
as tags rather than in the markdown-formatted code snippets. This is
documented in the API reference (see methods highlightAuto and
configure).
Objective C and C# now properly highlight titles in method definition.
Big overhaul of relevance counting for a number of languages. Please do report
bugs about mis-detection of non-trivial code snippets!
Version 7.5
A catch-up release dealing with some of the accumulated contributions. This one
is probably will be the last before the 8.0 which will be slightly backwards
incompatible regarding some advanced use-cases.
One outstanding change in this version is the addition of 6 languages to the
hosted script: Markdown, ObjectiveC, CoffeeScript, Apache, Nginx and
Makefile. It now weighs about 6K more but we’re going to keep it under 30K.
Ruby’s got support for characters like ?A, ?1, ?\012 etc. and %r{..}
regexps.
Clojure now allows a function call in the beginning of s-expressions
(($filter "myCount") (arr 1 2 3 4 5)).
Haskell’s got new keywords and now recognizes more things like pragmas,
preprocessors, modules, containers, FFIs etc. Thanks to Zena Treep
for the implementation and to Jeremy Hull for guiding it.
Miscellaneous fixes in PHP, Brainfuck, SCSS, Asciidoc, CMake, Python and F#.
New core developers
The latest long period of almost complete inactivity in the project coincided
with growing interest to it led to a decision that now seems completely obvious:
we need more core developers.
So without further ado let me welcome to the core team two long-time
contributors: Jeremy Hull and Oleg
Efimov.
Hope now we’ll be able to work through stuff faster!
P.S. The historical commit is here for the record.
Version 7.4
This long overdue version is a snapshot of the current source tree with all the
changes that happened during the past year. Sorry for taking so long!
Along with the changes in code highlight.js has finally got its new home at
http://highlightjs.org/, moving from its cradle on Software Maniacs which it
outgrew a long time ago. Be sure to report any bugs about the site to
info@highlightjs.org.
Literal regexes can now be used in language definitions.
CoffeeScript highlighting is now significantly more robust and rich due to
input from Cédric Néhémie.
Version 7.3
Since this version highlight.js no longer works in IE version 8 and older.
It’s made it possible to reduce the library size and dramatically improve code
readability and made it easier to maintain. Time to go forward!
Also Oleg Efimov did a great job of moving all the docs for language and style
developers and contributors from the old wiki under the source code in the
“docs” directory. Now these docs are nicely presented at
http://highlightjs.readthedocs.org/.
Version 7.2
A regular bug-fix release without any significant new features. Enjoy!
Version 7.1
A Summer crop:
Marc Fornos made the definition for Clojure along with the matching
style Rainbow (which, of course, works for other languages too).
CoffeeScript support continues to improve getting support for regular
expressions.
And last but not least, we’ve got a fair number of correctness and consistency
fixes, including a pretty significant refactoring of Ruby.
Version 7.0
The reason for the new major version update is a global change of keyword syntax
which resulted in the library getting smaller once again. For example, the
hosted build is 2K less than at the previous version while supporting two new
languages.
Notable changes:
The library now works not only in a browser but also with node.js. It is
installable with npm install highlight.js. API docs are available on our
wiki.
The new unique feature (apparently) among syntax highlighters is highlighting
HTTP headers and an arbitrary language in the request body. The most useful
languages here are XML and JSON both of which highlight.js does support.
Here’s the detailed post about the feature.
Two new style themes: a dark “south” Pojoaque by Jason Tate and an
emulation ofXCode IDE by Angel Olloqui.
Nginx syntax has become a million times smaller and more universal thanks to
remaking it in a more generic manner that doesn’t require listing all the
directives in the known universe.
Function titles are now highlighted in PHP.
Haskell and VHDL were significantly reworked to be more rich and correct
by their respective maintainers Jeremy Hull and Igor Kalnitsky.
And last but not least, many bugs have been fixed around correctness and
language detection.
Overall highlight.js currently supports 51 languages and 20 style themes.
Version 6.2
A lot of things happened in highlight.js since the last version! We’ve got nine
new contributors, the discussion group came alive, and the main branch on GitHub
now counts more than 350 followers. Here are most significant results coming
from all this activity:
Jeremy Hull has implemented my dream feature — a port of Solarized
style theme famous for being based on the intricate color theory to achieve
correct contrast and color perception. It is now available for highlight.js in
both variants — light and dark.
New major version of the highlighter has been built on a significantly
refactored syntax. Due to this it’s even smaller than the previous one while
supporting more languages!
P.S. New version is not yet available on a Yandex CDN, so for now you have to
download your own copy.
Version 5.14
Fixed bugs in HTML/XML detection and relevance introduced in previous
refactoring.
Also test.html now shows the second best result of language detection by
relevance.
Version 5.13
Past weekend began with a couple of simple additions for existing languages but
ended up in a big code refactoring bringing along nice improvements for language
developers.
For users
Description of C++ has got new keywords from the upcoming C++ 0x standard.
CSS-styles have been unified to use consistent padding and also have lost
pop-outs with names of detected languages.
Igor Kalnitsky has sent two new language descriptions: CMake & VHDL.
This makes total number of languages supported by highlight.js to reach 35.
Bug fixes:
Custom classes on <pre> tags are not being overridden anymore
More correct highlighting of code blocks inside non-<pre> containers:
highlighter now doesn’t insist on replacing them with its own container and
just replaces the contents.
Small fixes in browser compatibility and heuristics.
For developers
The most significant change is the ability to include language submodes right
under contains instead of defining explicit named submodes in the main array:
This is useful for auxiliary modes needed only in one place to define parsing.
Note that such modes often don’t have className and hence won’t generate a
separate <span> in the resulting markup. This is similar in effect to
noMarkup: true. All existing languages have been refactored accordingly.
Test file test.html has at last become a real test. Now it not only puts the
detected language name under the code snippet but also tests if it matches the
expected one. Test summary is displayed right above all language snippets.
CDN
Fine people at Yandex agreed to host highlight.js on their big fast servers.
Link up!
Version 5.10 — “Paris”.
Though I’m on a vacation in Paris, I decided to release a new version with a
couple of small fixes:
Tomas Vitvar discovered that TAB replacement doesn’t always work when used
with custom markup in code
SQL parsing is even more rigid now and doesn’t step over SmallTalk in tests
Version 5.9
A long-awaited version is finally released.
New languages:
Andrew Fedorov made a definition for Lua
a long-time highlight.js contributor Peter Leonov made a definition for
Nginx config
Loren Segal reworked the Ruby definition and added highlighting for
YARD inline documentation
the definition of SQL has become more solid and now it shouldn’t be overly
greedy when it comes to language detection
The highlighter has become more usable as a library allowing to do highlighting
from initialization code of JS frameworks and in ajax methods (see.
readme.eng.txt).
Jan Berkel has contributed a definition for Scala. +1 to hotness!
All CSS-styles are rewritten to work only inside <pre> tags to avoid
conflicts with host site styles.
Version 5.7.
Fixed escaping of quotes in VBScript strings.
Version 5.5
This version brings a small change: now .ini-files allow digits, underscores and
square brackets in key names.
Version 5.4
Fixed small but upsetting bug in the packer which caused incorrect highlighting
of explicitly specified languages. Thanks to Andrew Fedorov for precise
diagnostics!
Version 5.3
The version to fulfil old promises.
The most significant change is that highlight.js now preserves custom user
markup in code along with its own highlighting markup. This means that now it’s
possible to use, say, links in code. Thanks to Vladimir Dolzhenko for the
initial proposal and for making a proof-of-concept patch.
Also in this version:
Vasily Polovnyov has sent a GitHub-like style and has implemented
support for CSS @-rules and Ruby symbols.
Yura Zaripov has sent two styles: Brown Paper and School Book.
Ruslan Keba created highlighting for Apache config file. Also his
original visual style for it is now available for all highlight.js languages
under the name “Magula”.
The main change in the new major version of highlight.js is a mechanism for
packing several languages along with the library itself into a single compressed
file. Now sites using several languages will load considerably faster because
the library won’t dynamically include additional files while loading.
Also this version fixes a long-standing bug with Javascript highlighting that
couldn’t distinguish between regular expressions and division operations.
And as usually there were a couple of minor correctness fixes.
Great thanks to all contributors! Keep using highlight.js.
Version 4.3
This version comes with two contributions from Jason Diamond:
language definition for C# (yes! it was a long-missed thing!)
Visual Studio-like highlighting style
Plus there are a couple of minor bug fixes for parsing HTML and XML attributes.
Version 4.2
The biggest news is highlighting for Lisp, courtesy of Vasily Polovnyov. It’s
somewhat experimental meaning that for highlighting “keywords” it doesn’t use
any pre-defined set of a Lisp dialect. Instead it tries to highlight first word
in parentheses wherever it makes sense. I’d like to ask people programming in
Lisp to confirm if it’s a good idea and send feedback to the forum.
Other changes:
Smalltalk was excluded from DEFAULT_LANGUAGES to save traffic
Vladimir Epifanov has implemented javascript style switcher for
test.html
comments now allowed inside Ruby function definition
Ascetic from myself, as a realization of ideals of non-flashy highlighting:
just one color in only three gradations :-)
In other news. One small bug was fixed, built-in keywords were added for
Python and C++ which improved auto-detection for the latter (it was shame that
my wife’s blog had issues with it from time to time). And lastly
thanks go to Sam for getting rid of my stylistic comments in code that were
getting in the way of JSMin.
Version 4.0
New major version is a result of vast refactoring and of many contributions.
Visible new features:
Highlighting of embedded languages. Currently is implemented highlighting of
Javascript and CSS inside HTML.
Bundled 5 ready-made style themes!
Invisible new features:
Highlight.js no longer pollutes global namespace. Only one object and one
function for backward compatibility.
Performance is further increased by about 15%.
Changing of a major version number caused by a new format of language definition
files. If you use some third-party language files they should be updated.
Version 3.5
A very nice version in my opinion fixing a number of small bugs and slightly
increased speed in a couple of corner cases. Thanks to everybody who reports
bugs in he forum and by email!
There is also a new language — XML. A custom XML formerly was detected as HTML
and didn’t highlight custom tags. In this version I tried to make custom XML to
be detected and highlighted by its own rules. Which by the way include such
things as CDATA sections and processing instructions (<? ... ?>).
Version 3.3
Vladimir Gubarkov has provided an interesting and useful addition.
File export.html contains a little program that shows and allows to copy and
paste an HTML code generated by the highlighter for any code snippet. This can
be useful in situations when one can’t use the script itself on a site.
Version 3.2 consists completely of contributions:
Vladimir Gubarkov has described SmallTalk
Yuri Ivanov has described 1C
Peter Leonov has packaged the highlighter as a Firefox extension
Vladimir Ermakov has compiled a mod for phpBB
Many thanks to you all!
Version 3.1
Three new languages are available: Django templates, SQL and Axapta. The latter
two are sent by Dmitri Roudakov. However I’ve almost entirely rewrote an
SQL definition but I’d never started it be it from the ground up :-)
The engine itself has got a long awaited feature of grouping keywords
(“keyword”, “built-in function”, “literal”). No more hacks!
Version 3.0
It is major mainly because now highlight.js has grown large and has become
modular. Now when you pass it a list of languages to highlight it will
dynamically load into a browser only those languages.
Also:
Konstantin Evdokimenko of RibKit project has created a highlighting for
RenderMan Shading Language and RenderMan Interface Bytestream. Yay for more
languages!
Heuristics for C++ and HTML got better.
I’ve implemented (at last) a correct handling of backslash escapes in C-like
languages.
There is also a small backwards incompatible change in the new version. The
function initHighlighting that was used to initialize highlighting instead of
initHighlightingOnLoad a long time ago no longer works. If you by chance still
use it — replace it with the new one.
Version 2.9
Highlight.js is a parser, not just a couple of regular expressions. That said
I’m glad to announce that in the new version 2.9 has support for:
in-string substitutions for Ruby – #{...}
strings from from numeric symbol codes (like #XX) for Delphi
Version 2.8
A maintenance release with more tuned heuristics. Fully backwards compatible.
Version 2.7
Nikita Ledyaev presents highlighting for VBScript, yay!
A couple of bugs with escaping in strings were fixed thanks to Mickle
Ongoing tuning of heuristics
Fixed bugs were rather unpleasant so I encourage everyone to upgrade!
Version 2.4
Peter Leonov provides another improved highlighting for Perl
Javascript gets a new kind of keywords — “literals”. These are the words
“true”, “false” and “null”
Also highlight.js homepage now lists sites that use the library. Feel free to
add your site by dropping me a message until I find the time to build a
submit form.
Version 2.3
This version fixes IE breakage in previous version. My apologies to all who have
already downloaded that one!
Version 2.2
added highlighting for Javascript
at last fixed parsing of Delphi’s escaped apostrophes in strings
in Ruby fixed highlighting of keywords ‘def’ and ‘class’, same for ‘sub’ in
Perl
speed increased by orders of magnitude due to new way of parsing
this same way allows now correct highlighting of keywords in some tricky
places (like keyword “End” at the end of Delphi classes)
Version 1.0
Version 1.0 of javascript syntax highlighter is released!
It’s the first version available with English description. Feel free to post
your comments and question to highlight.js forum. And don’t be afraid
if you find there some fancy Cyrillic letters – it’s for Russian users too :-)
