For my Swift project, I'm trying to identify changes in the project.pbxproj file that have a particular word or regex in the surrounding context lines (not within the actual diff changes).
I've tried to use
git diff -G"<searchterm>"
But this seems to only apply the regex to the changes in the diff, not the surrounding context lines.
Tried also:
git diff -U# -G"<searchterm>"
but this doesn't alter the searchable lines.
example:
targeted diff looks like:
repositoryURL = "git@github.com:myRepo.git"
requirement = {
- branch = main;
- kind = branch;
+ kind = upToNextMajorVersion;
+ minimumVersion = 1.0.0;
};
};
running git diff -G"kind" or git diff -G"branch" will return a success, but git diff -G"repositoryURL" does not.
I would use grep and not try to leverage gits search for this.
Something like git diff | grep -A 5 myRepo
In your example would produce:
repositoryURL = git@github.com:myRepo.git
requirement = {
- branch = main;
- kind = branch;
+ kind = upToNextMajorVersion;
+ minimumVersion = 1.0.0;
For context control in grep, from the man page:
-A NUM, --after-context=NUM
Print NUM lines of trailing context after matching lines.
Places a line containing a group separator (--) between
contiguous groups of matches. With the -o or
--only-matching option, this has no effect and a warning
is given.
-B NUM, --before-context=NUM
Print NUM lines of leading context before matching lines.
Places a line containing a group separator (--) between
contiguous groups of matches. With the -o or
--only-matching option, this has no effect and a warning
is given.
-C NUM, -NUM, --context=NUM
Print NUM lines of output context. Places a line
containing a group separator (--) between contiguous
groups of matches. With the -o or --only-matching option,
this has no effect and a warning is given.
