10 | 10 | # Keyword expansion hack against the grain of a DSCM |
|
11 | 11 | # |
|
12 | 12 | # There are many good reasons why this is not needed in a distributed |
|
13 | 13 | # SCM, still it may be useful in very small projects based on single |
|
14 | 14 | # files (like LaTeX packages), that are mostly addressed to an |
|
15 | 15 | # audience not running a version control system. |
|
16 | 16 | # |
|
17 | 17 | # For in-depth discussion refer to |
|
18 | 18 | # <http://mercurial.selenic.com/wiki/KeywordPlan>. |
|
19 | 19 | # |
|
20 | 20 | # Keyword expansion is based on Mercurial's changeset template mappings. |
|
21 | 21 | # |
|
22 | 22 | # Binary files are not touched. |
|
23 | 23 | # |
|
24 | 24 | # Files to act upon/ignore are specified in the [keyword] section. |
|
25 | 25 | # Customized keyword template mappings in the [keywordmaps] section. |
|
26 | 26 | # |
|
27 | 27 | # Run "hg help keyword" and "hg kwdemo" to get info on configuration. |

29 | 29 | '''expand keywords in tracked files |
|
30 | 30 | |
|
31 | 31 | This extension expands RCS/CVS-like or self-customized $Keywords$ in |
|
32 | 32 | tracked text files selected by your configuration. |
|
33 | 33 | |
|
34 | 34 | Keywords are only expanded in local repositories and not stored in the |
|
35 | 35 | change history. The mechanism can be regarded as a convenience for the |
|
36 | 36 | current user or for archive distribution. |
|
37 | 37 | |
|
38 | 38 | Configuration is done in the [keyword] and [keywordmaps] sections of |
|
39 | 39 | hgrc files. |
|
40 | 40 | |
|
41 | 41 | Example:: |
|
42 | 42 | |
|
43 | 43 | [keyword] |
|
44 | 44 | # expand keywords in every python file except those matching "x*" |
|
45 | 45 | **.py = |
|
46 | 46 | x* = ignore |
|
47 | 47 | |
|
48 | 48 | NOTE: the more specific you are in your filename patterns the less you |
|
49 | 49 | lose speed in huge repositories. |
|
50 | 50 | |
|
51 | 51 | For [keywordmaps] template mapping and expansion demonstration and |
|
52 | 52 | control run "hg kwdemo". See "hg help templates" for a list of |
|
53 | 53 | available templates and filters. |
|
54 | 54 | |
|
55 | 55 | An additional date template filter {date|utcdate} is provided. It |
|
56 | 56 | returns a date like "2006/09/18 15:13:13". |
|
57 | 57 | |
|
58 | 58 | The default template mappings (view with "hg kwdemo -d") can be |
|
59 | 59 | replaced with customized keywords and templates. Again, run "hg |
|
60 | 60 | kwdemo" to control the results of your config changes. |
|
61 | 61 | |
|
62 | 62 | Before changing/disabling active keywords, run "hg kwshrink" to avoid |
|
63 | 63 | the risk of inadvertently storing expanded keywords in the change |
|
64 | 64 | history. |
|
65 | 65 | |
|
66 | 66 | To force expansion after enabling it, or a configuration change, run |
|
67 | 67 | "hg kwexpand". |
|
68 | 68 | |
|
69 | 69 | Also, when committing with the record extension or using mq's qrecord, |
|
70 | 70 | be aware that keywords cannot be updated. Again, run "hg kwexpand" on |
|
71 | 71 | the files in question to update keyword expansions after all changes |
|
72 | 72 | have been checked in. |
|
73 | 73 | |
|
74 | 74 | Expansions spanning more than one line and incremental expansions, |
|
75 | 75 | like CVS' $Log$, are not supported. A keyword template map "Log = |
|
76 | 76 | {desc}" expands to the first line of the changeset description. |
