S3QL is a file system that stores all its data online using storage
services like Google Storage, Amazon S3, or OpenStack. S3QL effectively
provides a hard disk of dynamic, infinite capacity that can be accessed
from any computer with internet access running Linux, FreeBSD or OS-X.
This script gives status information for code repositories found
recursively under a root directory. In particular, it tells whether
there are uncommitted changes, untracked files, unpushed or unpulled
commits. Thanks to the -u option, it is also useful to fetch updates
for all the remotes in the encountered repositories.
This should fix#7366 for now, but using the (IMHO) pragmatic approach
of extending the sed expression to recognize strings.
However, this approach is obviously not parsing the full AST, nor does
it wrap Python itself (as pointed out by @spwhitt in #7366) but tries to
match Python strings as best as possible without getting TOO unreadable.
We also use a little bit of Nix to help generating the SED expression,
because doing the whole quote matching block over and over again would
be quite repetitious and error-prone to change. The reason why I'm using
imap here is that we need to have unique labels to avoid jumping into
the wrong branch.
So the new expression is not only able to match continous regions of
triple-quoted strings, but also regions with only one quote character
(even with escaped inner quotes) and empty strings.
However, what it doesn't correctly recognize is something like this:
"string1" "string2" "multi
line
string"
Which is very unlikely that we'll find something like this in the wild.
Of course, we could handle it as well, but it would mean that we need to
substitute the current line into hold space until we're finished parsing
the strings, branch off to another label where we match multiline
strings of all sorts and swap hold/pattern space and finally print the
result. So to summarize: The SED expression would be 3 to 4 times bigger
than now and we gain very little from that.
