GeSHi - Generic Syntax Highlighter

Welcome to the home of the Generic Syntax Highlighter - GeSHi. GeSHi started as an idea to create a generic syntax highlighter for the phpBB forum system, but has been generalised to this project. GeSHi aims to be a simple but powerful highlighting class, with the following goals:

Support for a wide range of popular languages
Easy to add a new language for highlighting
Highly customisable output formats

GeSHi aims to do this all as quickly as possible. Many customisable features of GeSHi facilitate speed increases, and you can easily find a balance between the amount of highlighting done and the speed in which it is done.

GeSHi supports PHP5 and Windows, and has even been used to highlight code on ASP pages. Numerous blogs, wikis and forums use GeSHi, including Dokuwiki, Mambo, phpBB and WikkaWiki.

GeSHi is an award winning piece of software - so you know you're using a top quality product.

GeSHi on GitHub

2013/11/16
Since this week GeSHi has migrated to use Git for version control of the source code. Parallel to this move the source code hosting has moved away from SourceForge to GitHub Thus the old code at SourceForge is there only for historical reasons and will no longer be updated.

You can find more details on this change in my blog.

GeSHi Website available encrypted

2012/11/25
I recently decided to make the GeSHi website available via SSL as a related project requires use of SSL anyway. Currently I'm not yet forcing SSL, but if you connected successfully via SSL once you'll use it automatically for the next six months due to HSTS.

The reason I'm currently not enforcing is that as the used Certification Authority CAcert is not in the trusted store of Mozilla and Internet Explorer (although the second is not relevant to me) you'd probably get alot of confusing warnings. Thus as of now you should make a conscious choice to use the encrypted version of this website. If you do and you get an error "Issuer not trusted" please check the Certificate or verify the Root Certificate of CAcert is installed properly.

This change is available for qbnz.com and geshi.org.

GeSHi 1.0.8.11 Released

2012/08/19
Again quite some time has passed but here it is: the new release of GeSHi with loads of new languages, some minor parser tweaks and fixes to existing language files. It adds 18 more languages thus making a total of 219 supported languages.

This release includes two minor bugfixes for the contrib scripts shipped with GeSHi which allowed for Remote File Inclusion and Cross Side Scripting. Thus if you have the contrib scripts installed it is strongly advised to update ASAP. Some more details can be seen in my blog or in the changelog.

As already noted previously there's a problem with PCRE not working properly with some large sources: As I'm not a developer of PCRE, but a mere user I ask you to report issues with PCRE crashes upstream to them, not me.

More information on current GeSHi developement can be found in the GeSHi corner of my blog.

Download from the usual place, bug reports to the sf.net tracker please etc. etc...

GeSHi 1.0.8.10 Released

2011/02/11
After a quite long time of inactivity there is finally a new release of GeSHi with loads of new languages, some minor parser tweaks and fixes to existing language files. It adds 15 more languages thus making a total of 201 supported languages.

This release does introduce some minor changes into the parser improving the way numbers are highlighted and extending support for common number formats. Additionally it fixes many issues with highlighting that people noticed in the various language files. Some more details can be seen in my blog or in the changelog.

Also given a recent attack on the SourceForge.net systems I decided to take action and finally do what I already planned for quite some time: starting with 1.0.8.10 ALL (including old) releases of GeSHi will be signed. For details on how to check the used GnuPG signatures please refer to my blog. It is furthermore highly recommended to check the signatures

As already noted previously there's a problem with PCRE not working properly with some large sources: As I'm not a developer of PCRE, but a mere user I ask you to report issues with PCRE bugs upstream to them, not me.
