Subject: Question: libxdiff: text-patches: internal format
Message-ID: <20170323180026.7qdfdzqgyczt2s3f@darkstar>

Hi there,

Following up on an earlier question of mine from yesterday, is there any
formal documentation (save for source diving) on the internal format
used by libxdiff/xdiff when it generates a patch by comparing two
plaintext files?

I'd like to generate a human-readable "pretty" diff from the output
generated by libxdiff, and while the suggestion by Stefan yesterday is a
good idea (ie: go through diff.c), I'm trying to see if there's a
quicker way to pull this off. Also, I can't determine if lifting that
code from git would invoke LGPL licensing constraints (no problem), or
GPL licensing constraints (incompatible with my application). If the
format is easy enough to follow, I might just write my own parser,
provided it's a trivial task.

Thank you.
