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
Use-case: While not a vogue technology, VB is still a common file type taught in many university settings and used in many commercial settings. Working with VB files out-of-the-box would provide a lot of value to `ripgrep` users.
Example: I'm working on converting a legacy app to a modern infrastructure. The legacy app mixes CS and VB files liberally, so I always need to check both. For portability, it would be nice to just be able to ask for `-tcs -tvb` without registering with `--type-add` first.
Tests: I didn't notice any coverage aimed at this part of the code, but if I'm mistaken I'll amend the PR.
If you're in a directory that has a parent .gitignore (like, your $HOME),
then it can cause ripgrep to simply not do anything depending on your
ignore rules.
There are probably other scenarios where ripgrep applies some filter that
an end user doesn't expect, so try to catch the worst case (when ripgrep
doesn't search anything).
I don't like having multiple flags do the same thing, but -u, -uu and -uuu
are much easier to remember, particularly with -uuu meaning "search
everything."
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.
We do this by avoiding using a RegexSet (*sigh*). In particular, file
type matching has much simpler semantics than gitignore files, so we don't
actually need to care which file type matched. Therefore, we can get away
with a single regex with a giant alternation.
I though plain `read` had usurped them, but when searching a very small
number of files, mmaps can be around 20% faster on Linux. It'd be really
unfortunate to leave that on the table.
Mmap searching doesn't support contexts yet, but we probably don't really
care. And duplicating that logic doesn't sound fun. Without contexts, mmap
searching is delightfully simple.
