In the last months I've been making a songbook with chordpro https://www.chordpro.org/, amazing CLI program that produces a PDF from text files.

I've been working on my own arrangements, putting chords in lyrics, and the program produces a page with the chord diagrams next to each song. ChordPro is a program that descends from a long lineage of programs that do this, but it's been actively under development in the last 3-4 years. The developer is quite nice, and attends bug reports.
