Constant Summary collapse
- Version =
VERSION = '0.27.7'
- 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.
INT2FIX(GIT_SORT_REVERSE)
Class Method Summary collapse
-
.__cache_usage__ ⇒ Array
Returns an array representing the current bytes in the internal libgit2 cache and the maximum size of the cache.
-
.features ⇒ Array
Returns an array representing the features that libgit2 was compiled with — this includes ‘:threads` (thread support), `:https` and `:ssh`.
-
.hex_to_raw(oid) ⇒ Object
Turn a string of 40 hexadecimal characters into the buffer of 20 bytes it represents.
-
.libgit2_version ⇒ Object
Returns an array representing the current libgit2 version in use.
-
.minimize_oid(*args) ⇒ Object
Iterate through
oid_iterator
, which should yield any number of SHA1 OIDs (represented as 40-character hexadecimal strings), and tries to minify them. -
.prettify_message(message, strip_comments = '#') ⇒ Object
Process a commit or tag message into standard form, by stripping trailing spaces and comments, and making sure that the message has a proper header line.
-
.raw_to_hex(buffer) ⇒ Object
Turn a buffer of 20 bytes (representing a SHA1 OID) into its readable hexadecimal representation.
-
.signature_from_buffer(buffer[, encoding_name]) ⇒ Object
Parse the signature from the given buffer.
-
.valid_full_oid?(oid) ⇒ Boolean
Checks to see if a string contains a full 40-character sha1.

.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.

.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
