Extract footnote definitions

Goal: Collect every footnote definition in a document — e.g. to pull out a paper’s citations as a standalone reference list.

Prerequisites: None.

Query

.footnote

$ mq '.footnote' paper.md

Input

# Doc

Here is a claim[^1] and another[^2].

[^1]: First source.
[^2]: Second source.

Output

[^1]: First source.
[^2]: Second source.

Notes

  • This selects the footnote definitions (the [^1]: ... lines), not the inline reference marks ([^1]) in the body text.
  • Pipe through to_text to strip the [^n]: marker and get just the citation text.
