* bin/, man/: -m: Add flag, and pass it to pcre2grep(1)HEADmainAlejandro Colomar4 days-0/+5

* bin/grepc, grepc.1: -c: Add option to count matchesAlejandro Colomar2023-11-05-0/+4
| | | | | | As in pcre2grep(1) and grep(1). Signed-off-by: Alejandro Colomar <alx@kernel.org>
* bin/grepc, grepc.1: Rename option -c to -rAlejandro Colomar2023-11-05-4/+5
| | | | | | | This leaves -c unused, so we can add -c with the same meaning of grep(1): count. Signed-off-by: Alejandro Colomar <alx@kernel.org>

| | | | | | These flags are passed to pcre2grep(1). Signed-off-by: Alejandro Colomar <alx@kernel.org>
* bin/grepc, grepc.1: -h: Add option to suppress prefixing file namesAlejandro Colomar2023-11-05-0/+3
| | | | | | Equivalent to grep(1)'s -h, except that we always default to -H behavior. Signed-off-by: Alejandro Colomar <alx@kernel.org>
* bin/grepc, grepc.1: Remove -h flagAlejandro Colomar2023-11-05-3/+0
| | | | | | | | There's already a manual page, and the short help from -h was quite unhelpful. I want to reuse -h for grep(1)'s meaning (don't print the filename). Signed-off-by: Alejandro Colomar <alx@kernel.org>
* bin/grepc, grepc.1: Always enable recursive mode; remove -rAlejandro Colomar2023-11-05-11/+12
| | | | | | | | | | | | | | | The non-recursive behavior is so slow that it's quite useless. It is only useful when reading from standard input, but for several files it's useless. Make '-r' the default when any files are specified, and remove the flag (since now it's always enabled). This happens to bring back a behavior close to what we had before 55dd5d7255c8 ("Don't find files recursively"). Non-seekable files can still be read, if redirected to standard input. Update the example from the manual page to reflect current usage. Signed-off-by: Alejandro Colomar <alx@kernel.org>

* bin/grepc: OptimizeAlejandro Colomar2023-11-03-0/+7
| | | | | | | | | | | | | Call pcre2grep(1) only once, which allows removing named pipes. This is an important optimization, and will also allow accepting several file names in the command line (in a future commit). The source code is also significantly simplified. It has a caveat: this single call to pcre2grep(1) will consume more resources, and will crash on certain input files. The workaround is to restrict the search to just one or a few types of code. Document this in the manual page. This caveat only applies to very specific files, which so far I've only found in the Linux kernel source tree.
* Don't find files recursivelyAlejandro Colomar2023-11-03-6/+4
| | | | | | | | | | | | | | | grep only one file (or stdin). The current implementation doesn't allow filterin standard input, which I miss some times. I'm removing this feature now, to be able to rewrite most of the program in a way that allows filtering stdin, and then will consider adding back a recursive mode if necessary. Also, don't remove the two blanks at the start of the output, for consistency when calling this program via xargs(1), which will become more common now that it only handles single files.

* grepc, grepc.1: Remove -tu from the defaultsAlejandro Colomar2022-05-22-2/+2
| | | | | | | | | | | Normally, one either wants to see a declaration/definition, or its uses, but not both at the same time. Also, there are usually many more use sites than than definitions, and therefore definitions are shadowed between all the noise. Restrict the default to declarations and definitions, which in my experience seems to be the most common use case. Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>

* COPYING: Remove relative pathAlejandro Colomar2022-05-17-2/+0
| | | | | | | | | We have <share/licenses/> and <LICENSES/> in the repo, which should be enough to let people find the license. Anyway, when installed, different systems will likely have licenses installed in different places. Let's remove probably incorrect data. Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
* README: Remove pointer to examples/Alejandro Colomar2022-05-17-3/+0
| | | | | | | | | | | It contained a relative path, that would need a complex Makefile to keep correct after installation. Let's assume that <share/doc/grepc/> is easy to find, as it follows FHS, and a bit of intuition should do the rest. Anyway, the manual page contains an example.
