Overview
iG:Syntax Hiliter allows you to post source code to your site with syntax highlighting and formatting (as seen in code editors, IDEs). You can paste the code as is from your code editor or IDE and this plugin will take care of all the code colouring and preserve your formatting. It uses the GeSHi library to colourize your code and supports over a 100 programming languages. Most common languages are included with the plugin and it includes drop in support for more languages used by GeSHi.
NOTE : For fast results and less load on your server, you should have a cache plugin installed. That way the plugin won’t have to parse the code blocks on a post every time its loaded in browser.
Minimum Requirements
- WordPress 4.1 or above
- PHP 7.4.0 or above

Frequently Asked Questions
Changelog
v5.1
- Minimum required PHP version bumped to 7.4.0. The plugin simply won’t load its code on lower versions.
- Refactored plugin code for PHP 7.4.x for better performing code.
- This is the last release using the GeSHi library. GeSHi library has not been updated in several years and it looks unlikely that it will continue. Next release of the plugin will use a different syntax highlighting library. All existing shortcodes will continue to work and so the update and transition would be seamless for the most part, except a feature or two that will phase out and a few changes in plugin configuration options.
