It seems silly, but on *nix, we can just dump the bytes of the path
straight to the terminal. There's no need to do a UTF-8 check, which
can be costly when printing lots of matches.
This means that `rg pat < file` won't do the expected thing and search
`fil`. Instead, it will recursively search the current directory for `pat`.
This isn't ideal, but is better than the previous behavior, which was to
wait for stdin when running `rg pat`, given the appearance of hanging
forever. The former is an important use case, but the latter is the
*central* use case of ripgrep, so we should make that work.
`rg` can still be used to search stdin on Windows, it just needs to be
done explicitly. e.g., `rg pat - < file` will search for `pat` in `file`.
Fixes#19
If no paths are given to ripgrep, only read from stdin if it's a file or
a FIFO. In particular, if something like `rg foo < /dev/null` is used,
then don't try to read from stdin.

Closes#26.
Acts like --count but emits only the paths of files with matches,
suitable for piping to xargs. Both mmap and no-mmap searches terminate
after the first match is found. Documentation updated and tests added.
Files like /proc/cpuinfo will advertise themselves as a normal file with
size 0. Normally, this isn't a problem, but if ripgrep decides to use a
memory map, it skipped searching if the file was empty since it's an error
to memory map an empty file. Instead of returning 0, we should just fall
back to standard read calls.
Fixes#55.
A standard glob of `foo/**` will match `foo`, but gitignore semantics
specify that `foo/**` should only match the contents of `foo` and not
`foo` itself. We capture those semantics by translating `foo/**` to
`foo/**/*`.
Fixes#30.
This is kind of a ticky-tack change. I do think ./ as a prefix is
reasonable default, *but* we strip ./ when showing search results, so it
does make sense to be consistent.
Fixes#21.
If a gitignore file in a *parent* directory is used, then it must be
matched relative to the directory it's in. ripgrep wasn't actually
adhering to this rule. Consider an example:
.gitignore
src
llvm
foo
Where `.gitignore` contains `/llvm/` and `foo` contains `test`. When
running `rg test` at the top-level directory, `foo` is correctly searched.
If you `cd` into `src` and re-run the same search, `foo` is ignored because
the `/llvm/` pattern is interpreted with respect to the current working
directory, which is wrong. The problem is that the path of `llvm` is
`./llvm`, which makes it look like it should match.
We fix this by rebuilding the directory path of each file when traversing
gitignores in parent directories. This does come with a small performance
hit.
Fixes#25.
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
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.
