Hi,

I would like to ignore files if certain other files are present. In my 
special case, I want to ignore foo.pdf and foo.eps if foo.fig is 
present (both pdf and eps are generated on the fly but don't belong 
into repository). In general, I do NOT want to ignore pdf or eps. There 
are a lot of foos so I would like to have a general solution.

Is this possible?

Cheers
Sebastian

No.

You can script around it by making e.g. your build process (which
generated pdf/eps from fig) add a specific foo.pdf etc to .gitignore.

In fact, at the the time you add a fig to your repo you should add (&
commit) corresponding lines to .gitignore. This is the common approach.

Alternatively, you can update your ignore with

rm -f .gitignore;find . -name \*.fig | while read i;do echo -e
${i%fig}pdf "\n" ${i%fig}eps >>.gitignore;done

if you have no other ignore patterns in there. (This is q&d, adjust if
you have spaces in file names or such.)

I suggesting adding to your makefile a rule like

.gitignore: $(wildcard *.fig)
	(grep -ve \.pdf$ \.eps$ .gitignore;
	for i in $^; do echo $i; done | \
		sed -n 's/fig$/eps/p; s/eps$/pdf/p') > .gitignore.tmp
	mv .gitignore.tmp .gitignore
