Namely, if a .gitignore inside a sub-directory has an absolute pattern,
e.g., `/foo/`, then we should match it relative to the directory containing
the .gitignore.
We were erroneously neglecting to prefix a pattern like `foo/`
with `**/` (to make `**/foo/`) because it had a slash in it. In fact, the
only reason to neglect a **/ prefix is if the pattern already starts
with **/, or if the pattern is absolute.
Fixes#16, #49, #50, #65
For example, when only a single file (or stdin) is being searched, then we
should be able to print directly to the terminal instead of intermediate
buffers. (The buffers are only necessary for parallelism.)
Closes#4.
- Refactored interaction between CLI args and rest of xrep.
- Filling in a lot more options, including file type filtering.
- Fixing some bugs in globbing/ignoring.
- More documentation.
I'm pretty disappointed by the performance of regex sets. They are
apparently spending a lot of their time in construction of the DFA,
which probably means that the DFA is just too big.
It turns out that it's actually faster to build an *additional* normal
regex with the alternation of every glob and use it as a first-pass
filter over every file path. If there's a match, only then do we try the
more expensive RegexSet.
