I've given a quick look into `notmuch-show.c` (commit from
December 4) and indeed it seems quite trivial to add new formats.
Thus I wonder:
a) Is the code suitable for experimenting such a feature? (I mean
is the "overhaul" almost done, or still in progress?)
b) What would be the estimate for the "overhaul" completion? (To
start prototyping such a feature...)
c) Would someone else be interested in such a feature? (Or it's
something so remote that only the two of us stumbled upon it?)
I think it's quite hard to get this feature "right". I.e. I can
see the following different -- but equally likely -- use-cases:
* in my use-case I would need each line of the output to be a
standalone JSON object of an individual message; (thus I can script
with Bash `notmuch ... | while read message ; do ... ; done`;)
* maybe someone else would need that the output to contain
**exactly one** such message (maybe the first);
* and maybe for someone else the use case involves having no
`--entire-thread` by default;
* further more someone else would actually prefer a "flatten" list
of messages (not the currently nested list);
* or maybe the separator in the first use case should be `\0`
instead of `\n`;
Thanks,
Ciprian.
P.S.: I think all sub-commands that output line-feed separated
records should also have the option to split them instead with `\0`.
(I.e. `xargs` insists upon this I think, if not it separates by space
or new-line.)
