Question

我有一个包含大约800个变更集的Mercurial存储库，我需要找到第一个变量集，其中出现了示例这个词。该单词出现在.php文件中，而不是在提交注释等中。

最快/最简单的方法是什么？

Answer 1

尝试hg grep Example *.php

hg grep [OPTION]... PATTERN [FILE]...

search for a pattern in specified files and revisions

    Search revisions of files for a regular expression.

    This command behaves differently than Unix grep. It only
    accepts Python/Perl regexps. It searches repository
    history, not the working directory. It always prints the
    revision number in which a match appears.

    By default, grep only prints output for the first
    revision of a file in which it finds a match. To get it
    to print every revision that contains a change in match
    status ("-" for a match that becomes a non-match, or "+"
    for a non-match that becomes a match), use the --all
    flag.

options:

 -0 --print0              end fields with NUL
    --all                 print all revisions that match
 -f --follow              follow changeset history, or file
                          history across copies and renames
 -i --ignore-case         ignore case when matching
 -l --files-with-matches  print only filenames and revisions
                          that match
 -n --line-number         print matching line numbers
 -r --rev                 search in given revision range
 -u --user                list the author (long with -v)
 -d --date                list the date (short with -q)
 -I --include             include names matching the given
                          patterns
 -X --exclude             exclude names matching the given
                          patterns

use "hg -v help grep" to show global options

Answer 2

所选答案不完整： hg grep --all --files-with-matches 'PATTERN' [FILES] 通常是你想要的。

Answer 3

hg help filesets
...
"grep(regex)"
      File contains the given regular expression.

hg locate "set:grep(Example) and **.php"

或

hg locate "set:**.php and (**Example*)"

Answer 4

您可能要使用hg grep的--diff（不推荐使用--all）标志。它搜索差异而不是文件内容本身，这将导致，您将获得所有更改集/修订，其中出现或删除了示例一词。

现在要获得第一个匹配，您需要通过-r标志以revlog顺序传递此匹配。也就是说，修订版将从0到小费搜索。（ -r 0：tip ）

对于.php文件，您需要传递-I标志，用于文件名模式。

所以您的命令将是：

hg grep --all -r 0:tip "Example" -I "*.php"
