Motivation: I didn’t like the first code snippet plugin that I used because you had to edit the code in a different place than the post edition.
Solution: Now I’m using the Better WordPress Syntax Highlighter plugin. It is very easy to use in the post edition, you only need to add a specific <pre> tag.
Note: this post is deprecated, I moved to another plugin, see this new post.
Motivation: I want to publish code into my posts. I’m not really motivated to search or code anything so I’ll go for a plugin this time.
Solution: I found this plugin called “WordPress Code Snippet” which for me it’s okay. Maybe in the future I’ll search for another solution but right now it does the trick.
