Teach 'git-grep(1)' a new option, '--column-number', to show the column number of the first match on a non-context line. For example: $ ./git-grep -n --column-number foo | head -n3 .clang-format:51:14:# myFunction(foo, bar, baz); .clang-format:64:7:# int foo(); .clang-format:75:8:# void foo() Signed-off-by: Taylor Blau <me@xxxxxxxxxxxx> --- Documentation/git-grep.txt | 5 ++++- builtin/grep.c | 1 + t/t7810-grep.sh | 22 ++++++++++++++++++++++ 3 files changed, 27 insertions(+), 1 deletion(-) diff --git a/Documentation/git-grep.txt b/Documentation/git-grep.txt index 18b494731f..51dcfa5093 100644 --- a/Documentation/git-grep.txt +++ b/Documentation/git-grep.txt @@ -13,7 +13,7 @@ SYNOPSIS [-v | --invert-match] [-h|-H] [--full-name] [-E | --extended-regexp] [-G | --basic-regexp] [-P | --perl-regexp] - [-F | --fixed-strings] [-n | --line-number] + [-F | --fixed-strings] [-n | --line-number] [--column-number] [-l | --files-with-matches] [-L | --files-without-match] [(-O | --open-files-in-pager) [<pager>]] [-z | --null] @@ -169,6 +169,9 @@ providing this option will cause it to die. --line-number:: Prefix the line number to matching lines. +--column-number:: + Prefix the 1-indexed column number of the first match on non-context lines. + -l:: --files-with-matches:: --name-only:: diff --git a/builtin/grep.c b/builtin/grep.c index 5f32d2ce84..512f60c591 100644 --- a/builtin/grep.c +++ b/builtin/grep.c @@ -829,6 +829,7 @@ int cmd_grep(int argc, const char **argv, const char *prefix) GREP_PATTERN_TYPE_PCRE), OPT_GROUP(""), OPT_BOOL('n', "line-number", &opt.linenum, N_("show line numbers")), + OPT_BOOL(0, "column-number", &opt.columnnum, N_("show column number of first match")), OPT_NEGBIT('h', NULL, &opt.pathname, N_("don't show filenames"), 1), OPT_BIT('H', NULL, &opt.pathname, N_("show filenames"), 1), OPT_NEGBIT(0, "full-name", &opt.relative, diff --git a/t/t7810-grep.sh b/t/t7810-grep.sh index 1797f632a3..bbce57c8b1 100755 --- a/t/t7810-grep.sh +++ b/t/t7810-grep.sh @@ -99,6 +99,28 @@ do test_cmp expected actual ' + test_expect_success "grep -w $L (with --column-number)" ' + { + echo ${HC}file:5:foo mmap bar + echo ${HC}file:14:foo_mmap bar mmap + echo ${HC}file:5:foo mmap bar_mmap + echo ${HC}file:14:foo_mmap bar mmap baz + } >expected && + git grep --column-number -w -e mmap $H >actual && + test_cmp expected actual + ' + + test_expect_success "grep -w $L (with --{line,column}-number)" ' + { + echo ${HC}file:1:5:foo mmap bar + echo ${HC}file:3:14:foo_mmap bar mmap + echo ${HC}file:4:5:foo mmap bar_mmap + echo ${HC}file:5:14:foo_mmap bar mmap baz + } >expected && + git grep -n --column-number -w -e mmap $H >actual && + test_cmp expected actual + ' + test_expect_success "grep -w $L" ' { echo ${HC}file:1:foo mmap bar -- 2.17.0
