Constant Summary collapse

Version = 
VERSION = '0.28.3.1'
SORT_NONE =

Sort the output with the same default time-order method from git. This is the default sorting for new walkers.

INT2FIX(GIT_SORT_NONE)
SORT_TOPO =

Sort the repository contents in topological order (parents before children); this sorting mode can be combined with time sorting to produce git’s “time-order”.

INT2FIX(GIT_SORT_TOPOLOGICAL)
SORT_DATE =

Sort the repository contents by commit time; this sorting mode can be combined with topological sorting.

INT2FIX(GIT_SORT_TIME)
SORT_REVERSE =

Iterate through the repository contents in reverse order; this sorting mode can be combined with any of the above.

.hex_to_raw(oid) ⇒ Object

Turn a string of 40 hexadecimal characters into the buffer of 20 bytes it represents.

	return rb_str_new((const char *)oid.id, 20);
}

.libgit2_version ⇒ Object

Returns an array representing the current libgit2 version in use. Using the array makes it easier for the end-user to take conditional actions based on each respective version attribute: major, minor, rev.

Rugged.libgit2_version #=> [0, 17, 0]

	// We return an array of three elements to represent the version components
	return rb_ary_new3(3, INT2NUM(major), INT2NUM(minor), INT2NUM(rev));
}

.minimize_oid(oid_iterator, min_length = 7) {|short_oid| ... } ⇒ Object .minimize_oid(oid_iterator, min_length = 7) ⇒ Object

Iterate through oid_iterator, which should yield any number of SHA1 OIDs (represented as 40-character hexadecimal strings), and tries to minify them.

Minifying a set of a SHA1 strings means finding the shortest root substring for each string that uniquely identifies it.

If no block is given, the function will return the minimal length as an integer value:

oids = [
  'd8786bfc974aaaaaaaaaaaaaaaaaaaaaaaaaaaaa',
  'd8786bfc974bbbbbbbbbbbbbbbbbbbbbbbbbbbbb',
  'd8786bfc974ccccccccccccccccccccccccccccc',
  '68d041ee999cb07c6496fbdd4f384095de6ca9e1',
]

Rugged.minimize_oids(oids) #=> 12

If a block is given, it will be called with each OID from iterator in its minified form:

Rugged.minimize_oid(oids) { |oid| puts oid }

produces:

d8786bfc974a
d8786bfc974b
d8786bfc974c
68d041ee999c

The optional min_length argument allows you to specify a lower bound for the minified strings; returned strings won’t be shorter than the given value, even if they would still be uniquely represented.

Rugged.minimize_oid(oids, 18) #=> 18

Overloads:

  • .minimize_oid(oid_iterator, min_length = 7) {|short_oid| ... } ⇒ Object

    Yields:

    • (short_oid)
