2018-08-23interpret-trailers: allow suppressing "---" dividerLibravatar Jeff King1-0/+1
Even with the newly-tightened "---" parser, it's still possible for a commit message to trigger a false positive if it contains something like "--- foo". If the caller knows that it has only a single commit message, it can now tell us with the "--no-divider" option, eliminating any false positives. If we were designing this from scratch, I'd probably make this the default. But we've advertised the "---" behavior in the documentation since interpret-trailers has existed. Since it's meant to be scripted, breaking that would be a bad idea. Note that the logic is in the underlying trailer.c code, which is used elsewhere. The default there will keep the current behavior, but many callers will benefit from setting this new option. That's left for future patches.

"git interpret-trailers" has been taught a "--parse" and a few other options to make it easier for scripts to grab existing trailer lines from a commit log message. * jk/trailers-parse: doc/interpret-trailers: fix "the this" typo pretty: support normalization options for %(trailers) t4205: refactor %(trailers) tests pretty: move trailer formatting to trailer.c interpret-trailers: add --parse convenience option interpret-trailers: add an option to unfold values interpret-trailers: add an option to show only existing trailers interpret-trailers: add an option to show only the trailers trailer: put process_trailers() options into a struct
2017-08-15interpret-trailers: add --parse convenience optionLibravatar Jeff King1-0/+12
The last few commits have added command line options that can turn interpret-trailers into a parsing tool. Since they'd most often be used together, let's provide a convenient single option for callers to invoke this mode. This is implemented as a callback rather than a boolean so that its effect is applied immediately, as if those options had been specified. Later options can then override them. E.g.: git interpret-trailers --parse --no-unfold would work. Let's also update the documentation to make clear that this parsing mode behaves quite differently than the normal "add trailers to the input" mode.

2017-08-15interpret-trailers: add an option to unfold valuesLibravatar Jeff King1-0/+1
The point of "--only-trailers" is to give a caller an output that's easy for them to parse. Getting rid of the non-trailer material helps, but we still may see more complicated syntax like whitespace continuation. Let's add an option to unfold any continuation, giving the output as a single "key: value" line per trailer. As a bonus, this could be used even without --only-trailers to clean up unusual formatting in the incoming data.

2017-08-15interpret-trailers: add an option to show only existing trailersLibravatar Jeff King1-0/+7
It can be useful to invoke interpret-trailers for the primary purpose of parsing existing trailers. But in that case, we don't want to apply existing ifMissing or ifExists rules from the config. Let's add a special mode where we avoid applying those rules. Coupled with --only-trailers, this gives us a reasonable parsing tool.

2017-08-15interpret-trailers: add an option to show only the trailersLibravatar Jeff King1-0/+1
In theory it's easy for any reader who wants to parse trailers to do so. But there are a lot of subtle corner cases around what counts as a trailer, when the trailer block begins and ends, etc. Since interpret-trailers already has our parsing logic, let's let callers ask it to just output the trailers. They still have to parse the "key: value" lines, but at least they can ignore all of the other corner cases. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-08-14interpret-trailers: add options for actionsLibravatar Paolo Bonzini1-0/+32
Allow using non-default values for trailers without having to set them up in .gitconfig first. For example, if you have the following configuration trailer.signed-off-by.where = end you may use "--where before" when a patch author forgets his Signed-off-by and provides it in a separate email. Likewise for --if-exists and --if-missing Reverting to the behavior specified by .gitconfig is done with --no-where, --no-if-exists and --no-if-missing.

2017-08-10trailer: put process_trailers() options into a structLibravatar Jeff King1-7/+6
We already have two options and are about to add a few more. To avoid having a huge number of boolean arguments, let's convert to an options struct which can be passed in. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-01-14interpret-trailers: add option for in-place editingLibravatar Tobias Klauser1-4/+9
Add a command line option --in-place to support in-place editing akin to sed -i. This allows to write commands like the following: git interpret-trailers --trailer "X: Y" a.txt > b.txt && mv b.txt a.txt in a more concise way: git interpret-trailers --trailer "X: Y" --in-place a.txt Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-10-13trailer: add interpret-trailers commandLibravatar Christian Couder1-0/+44
This patch adds the "git interpret-trailers" command. This command uses the previously added process_trailers() function in trailer.c. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
