6 | 6 | """extend schemes with shortcuts to repository swarms |
|
7 | 7 | |
|
8 | 8 | This extension allows you to specify shortcuts for parent URLs with a |
|
9 | 9 | lot of repositories to act like a scheme, for example:: |
|
10 | 10 | |
|
11 | 11 | [schemes] |
|
12 | 12 | py = http://code.python.org/hg/ |
|
13 | 13 | |
|
14 | 14 | After that you can use it like:: |
|
15 | 15 | |
|
16 | 16 | hg clone py://trunk/ |
|
17 | 17 | |
|
18 | 18 | Additionally there is support for some more complex schemas, for |
|
19 | 19 | example used by Google Code:: |
|
20 | 20 | |
|
21 | 21 | [schemes] |
|
22 | 22 | gcode = http://{1}.googlecode.com/hg/ |
|
23 | 23 | |
|
24 | 24 | The syntax is taken from Mercurial templates, and you have unlimited |
|
25 | 25 | number of variables, starting with ``{1}`` and continuing with |
|
26 | 26 | ``{2}``, ``{3}`` and so on. This variables will receive parts of URL |
|
27 | 27 | supplied, split by ``/``. Anything not specified as ``{part}`` will be |
|
28 | 28 | just appended to an URL. |
|
29 | 29 | |
|
30 | 30 | For convenience, the extension adds these schemes by default:: |
|
31 | 31 | |
|
32 | 32 | [schemes] |
|
33 | 33 | py = http://hg.python.org/ |
|
34 | 34 | bb = https://bitbucket.org/ |
|
35 | 35 | bb+ssh = ssh://hg@bitbucket.org/ |
|
36 | 36 | gcode = https://{1}.googlecode.com/hg/ |
|
37 | kiln = https://{1}.kilnhg.com/Repo/ | |
|
37 | 38 | |
|
38 | 39 | You can override a predefined scheme by defining a new scheme with the |
|
39 | 40 | same name. |
