* grepc: Remove constraints in the file prefilteringAlejandro Colomar2022-05-25-1/+1

* grepc: Don't search underlying structure of a typedefAlejandro Colomar2022-05-25-14/+0
| | | | | | | | In some cases it might be nice, but in some other cases, it might cause a lot of code to be printed. Let the user explicitly search for it or not in a separate run. Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
* grepc: Fix glitch with incorrectly indented codeAlejandro Colomar2022-05-25-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid this glich from glibc: ./sysdeps/unix/sysv/linux/x86/sys/ucontext.h:133: typedef struct { gregset_t __ctx(gregs); /* Note that fpregs is a pointer. */ fpregset_t __ctx(fpregs); __extension__ unsigned long long __reserved1 [8]; } mcontext_t; /* Userlevel context. */ typedef struct ucontext_t { unsigned long int __ctx(uc_flags); struct ucontext_t *uc_link; stack_t uc_stack; mcontext_t uc_mcontext; sigset_t uc_sigmask; struct _libc_fpstate __fpregs_mem; __extension__ unsigned long long int __ssp[4]; } ucontext_t; Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
* grepc: Fix some typedef corner casesAlejandro Colomar2022-05-24-3/+3
| | | | | | | - Typedefs to arrays of structures. - Typedefs to structures of the same name. Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
* grepc: Improve regexesAlejandro Colomar2022-05-24-16/+16
| | | | | | | | - Use the same ammount of spaces for the closing brace as for the opening brace. - Fix position of attributes. Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
* grepc: bugfixAlejandro Colomar2022-05-22-2/+2
| | | | | | | SC2068: Double quote array expansions to avoid re-splitting elements. Reported-by: shellcheck(1) Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
* grepc: srcfixAlejandro Colomar2022-05-22-1/+1
| | | | | | | SC2124: Use $* instead of $@ to concatenate. Reported-by: shellcheck(1) Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
* grepc: srcfixAlejandro Colomar2022-05-22-1/+1
| | | | | | | SC2004: $/${} is unnecessary on arithmetic variables. Reported-by: shellcheck(1) Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
* grepc, grepc.1: Add -i flag as in grep(1)Alejandro Colomar2022-05-22-8/+12
| | | | | | Also, add some symmetry between ${iflag} and ${lflag}. Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
* grepc, grepc.1: Remove -tu from the defaultsAlejandro Colomar2022-05-22-1/+0
| | | | | | | | | | | 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>
* grepc, grepc.1: -tu: Allow searching special charactersAlejandro Colomar2022-05-20-7/+7
| | | | Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
* grepc: Fix grepc_type_typedef_underlying_struct_union_enumAlejandro Colomar2022-05-20-26/+43
| | | | | | | | | | | When it calls grepc_type_struct_union_enum(), it needs to use a different file list, since it's searching for an identifier different from the one passed in the command line. Also, while at it, improve the quoting of the pattern passed to pcregrep(1). Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>

* grepc: Usage: ffixAlejandro Colomar2022-05-11-1/+1
| | | | | | | | | | | | | | | | | Using caps instead of <> will be nicer when we add options and optional arguments for the files/directories: Usage: grepc [OPTION]... IDENTIFIER [FILE]... vs Usage: grepc [<option>]... IDENTIFIER [<file>]... Also, it's what pcregrep(1) and GNU grep(1) use, so it's good to use the same syntax here.

* grepc: grepc_linux_syscall_def: Improve readability of regexAlejandro Colomar2022-05-10-1/+1
| | | | | | | This improves the readability of the regex, and also the robustness, at the cost of just a few ms. Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
* grepc: grepc_find_files: Get a reduced list of files onceAlejandro Colomar2022-05-10-18/+27
| | | | | | | | | | Instead of running find and grep -l for every function, store the result in a temporary file for reuse in all functions. This is a considerable speedup, between 3x and 10x in some tests within the Linux kernel source code. Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
* grepc: Fix some corner casesAlejandro Colomar2022-05-10-2/+2
| | | | | | | | Those two spaces are for handling some insane GNU style. Those are always spaces, so let's use ' ' instead of '\s\s' to make sure we don't match two tabs, or things like that. Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>

* grepc: OptimizeAlejandro Colomar2022-05-09-7/+18
| | | | | | | | Use 2 grep(1) filters instead of 1, to be able to filter better before the multiline pcregrep(1) filter, which is considerably slower. Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
