I think that is a good idea. It also now quotes values that contain
control characters. In my experience quoting paths works well when one
is processing the output of one git command and feeding into the stdin
of another git command. In cases where the script itself wants to use
the path having to unquote them is a pain and it is much more convenient
to to read NUL terminated input "lines" that are not quoted. I think the
output from this command falls into that latter category and so I'm not
convinced that a LF terminated output is particularly useful. I think
using an output format generated by 'printf("%s\n%s\0", key, value)'
would be easier to parse. This format matches that used by 'git config
--list -z'.
As this is a plumbing command I think it would be clearer if the caller
was required to specify the output format and the information that they
require with an "--all" option for "show me everything" as Junio
suggested. If we were to set defaults for the format and keys now we
would be stuck with them forever.
I've not seen any discussion of how paths are going to be encoded in the
JSON output. As I understand it some JSON decoders only accept utf8
input but the paths reported by git are arbitrary NUL terminated byte
sequences. How is one expected to parse the output for a non utf8
encoded path using rust's JSON decoding for example?
On the subject of paths do you plan to support the equivalent of "git
rev-parse --git-path"? That is very useful in scripts as the script
author does not have to worry about the details of where exactly each
file lives and for paths like "index" or "hooks" it takes the relevant
environment variable or config setting into account. We should design
the output format so that it can accommodate keys with the requested
path. I think it would be reasonable to reject requests for paths
containing newlines which would be compatible with the output format
suggested above.
I'm not sure what the future plans for this command are but when I'm
scripting around git it would be nice to be able to a single process
that I could query for the things currently returned by "git rev-parse",
"git var" and "git config"
Best Wishes
Phillip
