Frequently Asked Questions
Common questions about Preserve Code Formatting
Are you using the visual editor? The visual editor has a tendency to screw up some of your intent, especially when you are attempting to include raw code. This plugin does not make any claims about working when you create posts with the visual editor enabled. How to tell if you're using the visual editor: you're using what is now referred to as the Classic Editor (the editing experience in WordPress that pre-dates the block editor since WordPress 5.0). Above the post content field and to the right, there is a tab labeled "Visual" and another labeled "Text". If you're writing code, you want to use "Text" for such posts and not switch back to "Visual".
Yes, shortcodes within code tags (or any tag processed by this plugin) will be output as pure text and not be processed as shortcodes by WordPress.
Yes, in the sense that it doesn't do anything at all. The code and preformatted blocks in the block editor should preserve code formatting without the need for this plugin. In short, the plugin will completely skip processing posts containing blocks. Use the code or preformatted blocks to format and display your code.
Only if you have older posts written in the text editor from before you began using the block editor. If so, then you would still want this plugin to be enabled so that those older posts have their code formatting preserved. This plugin being active will not interfere with posts created with blocks, all of which will be ignored by the plugin.
Asides from its intentional incompatibility with the block editor or classic visual editor, the main known issue with the plugin is its inability to properly recognize (and thus preserve) nested tags that match the tag being preserved. So within, for example, a tag, the first encountered will be treated as its closing tag even if technically that closing tag belongs to a nested 'code' tag, e.g. ``This examplewith nested code tags</code> will be rendered as if that first/inner closing tag belonged to the first/outer 'code' tag. It was a choice between either supporting the above scenario (which seems pretty rare overall) or supporting having multiple adjacent preserved tags in a post (which is much more common). A more robust solution is being pursued.
Yes. The tests are not packaged in the release .zip file or included in plugins.svn.wordpress.org, but can be found in the plugin's GitHub repository. The tests are expecting to be run with PHPUnit 9 and you'll likely experience errors if running them under another version.
