How to filter away entire sections?

[chrgro]

Hi, excellent tool, thanks! :)

I am however stumped at one particular problem: I'd like to filter away particular sections, by section depth. I couldn't figure out that out even with a lot of trials in the playground. For example I may have this .md:

# My first main section

Some body text here

| Random table       |
|--------------------|
| Some table content | 

### Subsection

I want to filter away this entire level-3 section.

# Other section

## Not so deep section

This section should be kept

And I want to remove only the level-3 subsection but keep everything else, i.e. the output should be like this:

# My first main section

Some body text here

| Random table       |
|--------------------|
| Some table content | 

# Other section

## Not so deep section

This section should be kept

Doing this like for example

include "section"
 nodes | filter(fn(s): s || s.level < 2;) 

just leaves me with the headers and not the content. Any help is deeply appreciated :)

Hi!

Right now, you’ll need to write a custom function for this. But the next version of mq will have a built-in filter_sections function, so it’ll be much easier.

With the new release, you can just do:

include "section" | nodes | filter_sections(fn(x): level(x) < 3;) | collect()

You can try this feature in the playground:

If you want to try it, you can install the latest version with:

cargo install --git https://github.com/harehare/mq.git mq-run --bin mq

Hope that helps! If you have any other questions, just let me know!

That works beautifully, thanks a lot! I had to use include "section" instead of import to get the functions in scope and not use the full :: syntax, but otherwise ran out of the box with the newest version.
