Frequently Asked Questions

Common questions about iG:Syntax Hiliter

If you are writing your post in the classic editor's Visual (WYSIWYG) tab then that is what is messing things up for you. That tab is TinyMCE, it treats your code as HTML and it does its damage before this plugin ever sees the content. It has never been supported. Use the block editor or the classic editor's Code view. If you are using either of those and still see this, please report it.

Because leaving them alone was worse. See the Important changes in 6.0.0 section above for the full explanation. Short version: the block editor loads a classic post into one big TinyMCE block, TinyMCE eats code and converting the snippets to blocks first is the only way to stop that. The conversion is only written to the post if you save it and it leaves the rest of your post byte-for-byte as it was.

Snippets still stored as shortcodes stay visible as [sourcecode]…[/sourcecode] text — ugly, but you can see them and do something about them. Snippets that have been converted to blocks render as nothing at all, because the block is no longer registered, and a Gist block goes the same way. Before deactivating, use the tool in the Before you deactivate section of the plugin's settings page to turn those blocks back into shortcodes — [sourcecode] for a code block and [github] for a Gist block. Every block converts, this plugin's own tags in the code included.

Both of those mechanisms are gone with GeSHi. Approx 300 languages ship with the plugin now, so start by checking whether yours is one of them — use it with [sourcecode language="…"] or pick it in the block.

[sourcecode language="php"] [[sourcecode language="php"]] echo 'hello'; [[/sourcecode]] [/sourcecode] Without this the snippet would end at the first closing tag in its code and everything after it would be lost. What is stored is what you typed — the extra brackets come off on the way to a reader and nowhere else — and the rule applies to itself, so [[[/php]]] shows a reader [[/php]].

By all means, feel free to submit a pull request.

Please feel free to suggest a new feature. Its inclusion might be speedier if you can provide the code to make it work.
