This should bring a compilation time improvement when building static
buils of PCRE2 by enabling parallelism for C compilation.
Kudos to @JoshTriplett for the tip!
We use '+++' syntax to output a literal '**' for a '--glob' example.
This '+++' syntax is pretty ugly when rendered literally via --help. We
fix this by hackily inserting the '+++' syntax for its one specific case
that we need it during man page generation.
Not ideal but it works. And --help still has some '*foo*' markup, but we
live with that for now.
Fixes#1581
The steps are numerous, subtle and complex enough that it's worth
writing them down. In particular, getting the order correct is
important. (i.e., If we released to crates.io first and the GitHub
release infrastructure failed, then we'd be in a pickle.)
Adds `WalkBuilder::filter_entry` that takes a predicate to be applied to
all entries. If the predicate returns `false` on a given entry, that
entry and all children will be skipped.
Fixes#1555, Closes#1557
While Linux distributions (at least Arch Linux, RHEL, Debian) do not support
compressing files with compress(1), macOS & AIX do (the utility is part of
POSIX). Additionally, gzip is able to uncompress such compressed files and
provides an `uncompress` binary.
Closes#1547
It has grown quite long. It would be nice if we could shorten this only
when -h is used and keep it long for --help, but it seems clap doesn't
let this happen. (It does have `about` and `long_about` options, but
they don't work, even when I disable the use of the template.)
The longer prelude is now only available in the man page.
This addresses #189.
When a pattern with invalid UTF-8 is given, the error message suggests
unqualified use of hex escape sequences to match arbitrary bytes. But
you *also* need to disable Unicode mode. So include that in the error
message.
Fixes#1339
In order to implement --count-matches, we simply re-execute the regex on
the spans reported by the searcher. The spans always correspond to the
lines that participated in the match. This is the correct thing to do,
except when the regex contains look-ahead (or look-behind).
In particular, the look-around permits the regex's match success to
depends on an arbitrary point before or after the lines actually
reported as participating in the match. Since only the matched lines are
reported to the printer, it is possible for subsequent searching on
those lines to fail.
A true fix for this would somehow make the total span available to the
printer. But that seems tricky since it isn't always available. For
PCRE2's case in multiline mode, it is available because we force it to
be so for correctness.
For now, we simply detect this corner case heuristically. If the match
count is zero, then it necessarily means there is some kind of
look-around that isn't matching. So we set the match count to 1. This is
probably incorrect in some cases, although my brain can't quite come up
with a concrete example. Nevertheless, this is strictly better than the
status quo.
Fixes#1573
