NAME

Regexp::Pattern::Git - Regexp patterns related to git

VERSION

This document describes version 0.001 of Regexp::Pattern::Git (from Perl distribution Regexp-Pattern-Git), released on 2019-10-24.

SYNOPSIS

use Regexp::Pattern; # exports re()
my $re = re("Git::ref");

DESCRIPTION

Regexp::Pattern is a convention for organizing reusable regex patterns.

PATTERNS

  • ref

    Valid reference name.

    This single regex pattern enforces the rules defined by the git-check-ref-format manpage, reproduced below:

    1. They can include slash / for hierarchical (directory) grouping, but no slash-separated component can begin with a dot . or end with the sequence .lock.
    2. They must contain at least one /. This enforces the presence of a category like heads/, tags/ etc. but the actual names are not restricted.
    3. They cannot have two consecutive dots .. anywhere.
    4. They cannot have ASCII control characters (i.e. bytes whose values are lower than \040, or \177 DEL), space, tilde ~, caret ^, or colon : anywhere.
    5. They cannot have question-mark ?, asterisk *, or open bracket [ anywhere.
    6. They cannot begin or end with a slash / or contain multiple consecutive slashes.
    7. They cannot end with a dot ..
    8. They cannot contain a sequence @{.
    9. They cannot be the single character @.
    10. They cannot contain a .

    Examples:

    "foo/bar" =~ re("Git::ref");  # matches

# A slash-separated component begins with dot (rule 1)
".foo/bar" =~ re("Git::ref");  # doesn't match

# A slash-separated component begins with dot (rule 1)
"foo/.bar" =~ re("Git::ref");  # doesn't match

# A slash-separated component ends with ".lock" (rule 1)
"foo.lock/bar" =~ re("Git::ref");  # doesn't match

"foo.locker/bar" =~ re("Git::ref");  # matches

# A slash-separated component ends with ".lock" (rule 1)
"foo/bar.lock" =~ re("Git::ref");  # doesn't match

# A slash-separated component ends with ".lock" (rule 1)
"foo/bar.lock/baz" =~ re("Git::ref");  # doesn't match

"foo/bar.locker/baz" =~ re("Git::ref");  # matches

# Does not contain at least one / (rule 2)
"foo" =~ re("Git::ref");  # doesn't match

# Contains two consecutive dots (rule 3)
"foo../bar" =~ re("Git::ref");  # doesn't match

# Contains colon (rule 4)
"foo:/bar" =~ re("Git::ref");  # doesn't match

# Contains question mark (rule 5)
"foo?/bar" =~ re("Git::ref");  # doesn't match

# Contains open bracket (rule 5)
"foo[2]/bar" =~ re("Git::ref");  # doesn't match

# Begins with / (rule 6)
"/foo/bar" =~ re("Git::ref");  # doesn't match

# Ends with / (rule 6)
"foo/bar/" =~ re("Git::ref");  # doesn't match

# Contains multiple consecutive slashes
"foo//bar" =~ re("Git::ref");  # doesn't match

# Ends with . (rule 7)
"foo/bar." =~ re("Git::ref");  # doesn't match

# Contains sequence @{ (rule 8)
"foo\@{/bar" =~ re("Git::ref");  # doesn't match

# Contains sequence @{ (rule 8)
"foo\@{baz}/bar" =~ re("Git::ref");  # doesn't match

# Cannot be single character @ (rule 9)
"\@" =~ re("Git::ref");  # doesn't match

  • release_tag

    Common release tag pattern.

    This is not defined by git, but just common convention.

    Examples:

    # Does not contain digit
"release" =~ re("Git::release_tag");  # doesn't match

1 =~ re("Git::release_tag");  # matches

"1.23-456-foobar" =~ re("Git::release_tag");  # matches

"release-1.23" =~ re("Git::release_tag");  # matches

"v1.23" =~ re("Git::release_tag");  # matches

"ver-1.23" =~ re("Git::release_tag");  # matches
