unexpected output when diffing files not in repository root

[seebi]

Hi norman and nate,

I tried to test quitdiff but got an unexpected diff output.

I opened an existing turtle file in a repository and added a triple there (an additional comment). Then I ran git diff in order to have the standard output to compare it with quitdiff. here it is:

∴ git diff
diff --git a/data/aksw.ttl b/data/aksw.ttl
index 0a1f015..680f2f9 100644
--- a/data/aksw.ttl
+++ b/data/aksw.ttl

The I ran quitdiff with the documented config (git difftool -t quitdiff-eccrev) but got a huge changeset of just deleting everything and then inserting everything.

I expected to get only one triple in the diff.

Hey @seebi can you try to run git difftool -dir-diff -t quitdiff-eccrev

It may be that rdf serializations using triples (not quads) will be parsed in a named graph assigned by the absolute file path (a/data/aksw.ttl vs. b/data/aksw.ttl).

Using -dir-diff may help until we fix this issue, since the files are handled in a different way.

Norm, by using --dir-diff only empty changesets are generated

3 should fix this.

Add a walk through subdirectories. Add a default named graph URI so file names won't be taken as named graph URI.
