The discussion explores how to add line numbers to code blocks in Discourse. jmsachs references a 2021 post but seeks clarification on implementation. Unit_72 explains that Discourse doesn’t natively support line numbers, but the “Code Review” plugin can enable this feature using the line_numbers attribute in Markdown. merefield notes that the solution involves CSS and suggests checking the original thread for details, while also highlighting the need to verify AI-generated advice due to potential inaccuracies. Lilly shares a custom theme component for line numbers, providing a practical solution and linking to a new topic for further details Lilly.
I found this post from 2021 Is it possible to show line numbers in code block? but no idea how to apply it.
I asked the AI, I’m not sure if this will help:
To solve the problem of showing line numbers in a code block on Discourse, here’s what you need to do:
Discourse does not have a built-in feature to display line numbers in code blocks. However, there is a plugin that can help you achieve this.
The plugin is called “Code Review” (formerly known as “Code Line Numbers”). To use this plugin, you’ll need to:
line_numbers attribute to your code block Markdown. For example:```python line_numbers
def hello_world():
print("Hello, World!")
This will render the code block with line numbers.
Note: The line_numbers attribute may have been renamed or modified in newer versions of the plugin. If you’re unsure, check the plugin documentation or consult with your Discourse administrator.
If you’re still having trouble, feel free to ask, and I’ll do my best to help!
That Topic contains the CSS they used which you could experiment with in your own local Component.
See from this post onwards
Shame no one has packaged that into a Theme Component on GitHub for easier consumption?
Did you try it? It’s best I think to check AI provided solutions before posting as gospel.
I stated that I asked the AI, because it seems to be very helpful and underused in the case of helping. Though I did not have much knowledge on this plugin, I still wanted to help.
AI can hallucinate and old information it might have relied upon can get out of date and lose relevance - hence worth checking.
Which AI? (gratuitous content to meet the 10-character minimum)
Ah, ok… everyone is jumping on the AI bandwagon I guess
