* grep: -r with no args now searches "."Paul Eggert2012-01-025-21/+60
| | | | | | | | | | | | | | | | | | | This is a patch I've been meaning to put in for years. When I added support for "grep -r", I forgot to have "grep -r PAT" search the working directory by default, instead of searching standard input (which makes no sense, even if stdin is a directory). This is not an upward compatible change, since "grep -r PAT <file" will no longer search standard input, but that's OK; nobody should be using "grep -r" that way anyway. * NEWS: Document this. * doc/grep.texi (File and Directory Selection, grep Programs, Usage): Likewise. * src/main.c (usage): Likewise. (grepdir): If DIR is null, search the working directory, but do not prepend "./" to the file names. (main): If recursing and no operands are given, search ".". * tests/Makefile.am (TESTS): Add r-dot. * tests/r-dot: New file.
* grep: prefer fgets to printf, _ to gettextPaul Eggert2012-01-023-4/+4
| | | | | | | * lib/colorize.h (print_end_colorize): * lib/ms/colorize-impl.c (print_end_colorize): Use fputs instead of printf. * src/main.c (usage): Likewise. Use _ instead of gettext.
* grep: check stdin like other filesPaul Eggert2012-01-013-59/+86
| | | | | | | | | | | * NEWS: Document this. * src/main.c (grepfile): Revamp tests for input files so that standard input is tested like other files. For example, report an error if standard input equals standard output. Prefer open+fstat to stat+open if possible, as open+fstat is usually a bit faster and avoids a race condition. * tests/in-eq-out-infloop: Add tests for cases like 'grep pat <file >>file'.
* maint: update all copyright year number rangesJim Meyering2012-01-0171-71/+72
| | | | Run "make update-copyright".
* grep: lower-case function namesPaul Eggert2011-12-311-19/+19
| | | | | | | | | These names used to be macros, but they're functions now. All callers changed. * src/main.c (pr_sgr_start): Rename from PR_SGR_START. (pr_sgr_end): Rename from PR_SGR_END. (pr_sgr_start_if): Rename from PR_SGR_START_IF. (pr_sgr_end_if): Rename from PR_SGR_END_IF.
* ms: move Microsoft-specific stuff to lib/msPaul Eggert2011-12-3110-226/+337
| | | | | | | | | | | | | | | | | | | | | | | * cfg.mk (exclude_file_name_regexp--sc_prohibit_strcmp) (exclude_file_name_regexp--sc_require_config_h) (exclude_file_name_regexp--sc_require_config_h_first): New rules. * lib/colorize.c, lib/colorize.h, lib/colorize-impl.c: * lib/ms/colorize.h, lib/ms/colorize-impl.c: New files. * configure.ac (GREP_SRC_INCLUDES): New macro. * lib/Makefile.am (libgreputils_a_SOURCES): Add colorize.[ch]. (EXTRA_DIST): New macro. * src/Makefile.am (DEFAULT_INCLUDES): New macro. * src/main.c: Include colorize.h. (PR_SGR_START, PR_SGR_END, PR_SGR_START_IF, PR_SGR_END_IF): Now static functions, not macros. (hstdout, norm_attr, w32_console_init, w32_sgr2attr) (w32_clreol) [__MINGW32__]: Move to lib/ms/colorize-impl.c. (pr_sgr_start, pr_sgr_end): Remove; callers changed to use new print_start_colorize, print_end_colorize from colorize.h. (init_colorize): Rename from w32_console_init and move to colorize module; caller changed. (should_colorize): Move to colorize module.
* grep: do input==output check more like dir loop checkPaul Eggert2011-12-312-41/+2
| | | | | | | | | | * src/main.c (grepfile): Just use SAME_INODE; don't bother with SAME_REGULAR_FILE. This works better on properly-working POSIX hosts, since it handles the case where the file is changing as we grep it. It works worse on hosts that don't support st_ino properly, but in practice this isn't that much of a problem here. * src/system.h (same_file_attributes, SAME_REGULAR_FILE): Remove; no longer needed.

* don't ignore errors when reading a directoryPaul Eggert2011-12-243-41/+11
| | | | | | | | | | | grep no longer silently suppresses errors when reading a directory as if it were a text file. For example, "grep x ." now reports a read error on most systems; formerly, it ignored the error. Problem reported as an aside by Bob Proulx (Bug#10355). * NEWS: Document this. * src/main.c (grep, grepfile): Implement this. Simplify the code considerably. * src/system.h (is_EISDIR): Remove; no longer needed.
* --include etc. now work on command-line args more consistentlyPaul Eggert2011-12-243-9/+31
| | | | | | | | | | --include and --exclude apply only to non-directories and --exclude-dir applies only to directories. "-" (standard input) is never excluded, since it is not a file name. This bug was discovered while fixing a read-directory bug (Bug#10355). * NEWS: Document this. * src/main.c (main): Implement this. * tests/include-exclude: Test for it.

* doc: improve grep.texiArnold D. Robbins2011-12-121-154/+190
| | | | | * doc/grep.texi: General editing for improved aesthetics. Also fix a few problems.
* build: use gnulib's iswctype wcscollJim Meyering2011-12-123-13/+4
| | | | | | | | | * bootstrap.conf (gnulib_modules): Add iswctype and wcscoll. * configure.ac: Remove explicit checks for those functions. * src/mbsupport.h (MBS_SUPPORT): Define to 1 if not already defined. Remove the conditional, now that we're guaranteed by gnulib to have wcscoll and iswctype. Suggested by Alan Hourihane in http://savannah.gnu.org/bugs/?34930
* disable the new input==output guard for additional optionsJim Meyering2011-12-123-4/+35
| | | | | | | * src/main.c (grepfile): Do not reject input == output also when using a few other options. * tests/in-eq-out-infloop: Test these new cases. * NEWS (Bug fixes): Mention it
* do not reject "grep -qr . > out"Nicolas Vigier2011-12-111-2/+4
| | | | | | | | | | | | The recent fix to avoid an infinite disk-filling loop, commit 5e20a38a, introduced a minor regression. If you use grep with -q and -r, and redirect output to a file that will be traversed, then grep would reject the command, even though it will generate no output. In that case, there is no risk of an infinite loop. * src/main.c (grepfile): Do not reject input == output when using --quiet/--silent (-q). Reported by J H Wilson in http://bugs.mageia.org/show_bug.cgi?id=3501 forwarded by Nicolas Vigier to https://savannah.gnu.org/bugs/?34917
* dfa: do not call nl_langinfo in !MBS_SUPPORT modeArnold Robbins2011-11-291-1/+1
| | | | | | * src/dfa.c (using_utf8) [!MBS_SUPPORT]: Remove erroneous "defined" in cpp test for MBS_SUPPORT. Since commit a163349d, MBS_SUPPORT is 0/1. This error caused trouble only in the !MBS_SUPPORT case.
* dfa: avoid warning from deficient compiler in !MBS_SUPPORT modeArnold Robbins2011-11-291-1/+7
| | | | | * src/dfa.c (setbit_wc) [!MBS_SUPPORT]: Add explicit "return false;" after "abort ();", to avoid a warning from deficient compilers.
