Show all unchanged lines

[Zebradil]

How to instruct delta to output all lines when diffing two files?
This only shows differences with some context around them:

delta 1.txt 2.txt

For example, diff -y 1.txt 2.txt does show all lines from the files.

delta 1.txt 2.txt calls an external diff tool, but the passed arguments can't be changed. But you can call this tool yourself, and then pipe that to delta:

git diff --no-index -U9999 1.txt 2.txt | delta
or
diff -U9999 1.txt 2.txt | delta

I didn't know that you can specify a context size with the diff's -U flag. Thanks!

Thanks @th1000s. I've opened a PR #1697 adding an option --diff-args=... (short form -@=...) allowing extra arguments to git diff to be passed from the delta command line, as suggested by @calestyo in #1644 (comment).
