|
297 | 302 | - CVS |
|
298 | 303 | - Darcs |
|
299 | 304 | - git |
|
300 | 305 | - Subversion |
|
301 | 306 | |
|
302 | 307 | Accepted destination formats: |
|
303 | 308 | - Mercurial |
|
304 | 309 | |
|
305 | 310 | If no revision is given, all revisions will be converted. Otherwise, |
|
306 | 311 | convert will only import up to the named revision (given in a format |
|
307 | 312 | understood by the source). |
|
308 | 313 | |
|
309 | 314 | If no destination directory name is specified, it defaults to the |
|
310 | 315 | basename of the source with '-hg' appended. If the destination |
|
311 | 316 | repository doesn't exist, it will be created. |
|
312 | 317 | |
|
313 | 318 | If <revmapfile> isn't given, it will be put in a default location |
|
314 | 319 | (<dest>/.hg/shamap by default). The <revmapfile> is a simple text |
|
315 | 320 | file that maps each source commit ID to the destination ID for |
|
316 | 321 | that revision, like so: |
|
317 | 322 | <source ID> <destination ID> |
|
318 | 323 | |
|
319 | 324 | If the file doesn't exist, it's automatically created. It's updated |
|
320 | 325 | on each commit copied, so convert-repo can be interrupted and can |
|
321 | 326 | be run repeatedly to copy new commits. |
|
322 | 327 | |
|
323 | 328 | The [username mapping] file is a simple text file that maps each source |
|
324 | 329 | commit author to a destination commit author. It is handy for source SCMs |
|
325 | 330 | that use unix logins to identify authors (eg: CVS). One line per author |
|
326 | 331 | mapping and the line format is: |
|
327 | 332 | srcauthor=whatever string you want |
|
328 | 333 | |
|
329 | 334 | The filemap is a file that allows filtering and remapping of files |
|
330 | 335 | and directories. Comment lines start with '#'. Each line can |
|
331 | 336 | contain one of the following directives: |
|
332 | 337 | |
|
333 | 338 | include path/to/file |
|
334 | 339 | |
|
335 | 340 | exclude path/to/file |
|
336 | 341 | |
|
337 | 342 | rename from/file to/file |
|
338 | 343 | |
|
339 | 344 | The 'include' directive causes a file, or all files under a |
|
340 | 345 | directory, to be included in the destination repository. The |
|
341 | 346 | 'exclude' directive causes files or directories to be omitted. |
|
342 | 347 | The 'rename' directive renames a file or directory. To rename |
|
343 | 348 | from a subdirectory into the root of the repository, use '.' as |
|
344 | 349 | the path to rename to. |

1 | hg convert [OPTION]... SOURCE [DEST [MAPFILE]] | |
|
2 | ||
|
3 | Convert a foreign SCM repository to a Mercurial one. | |
|
4 | ||
|
5 | Accepted source formats: | |
|
6 | - CVS | |
|
7 | - Darcs | |
|
8 | - git | |
|
9 | - Subversion | |
|
10 | ||
|
11 | Accepted destination formats: | |
|
12 | - Mercurial | |
|
13 | ||
|
14 | If no revision is given, all revisions will be converted. Otherwise, | |
|
15 | convert will only import up to the named revision (given in a format | |
|
16 | understood by the source). | |
|
17 | ||
|
18 | If no destination directory name is specified, it defaults to the | |
|
19 | basename of the source with '-hg' appended. If the destination | |
|
20 | repository doesn't exist, it will be created. | |
|
21 | ||
|
22 | If <revmapfile> isn't given, it will be put in a default location | |
|
23 | (<dest>/.hg/shamap by default). The <revmapfile> is a simple text | |
|
24 | file that maps each source commit ID to the destination ID for | |
|
25 | that revision, like so: | |
|
26 | <source ID> <destination ID> | |
|
27 | ||
|
28 | If the file doesn't exist, it's automatically created. It's updated | |
|
29 | on each commit copied, so convert-repo can be interrupted and can | |
|
30 | be run repeatedly to copy new commits. | |
|
31 | ||
|
32 | The [username mapping] file is a simple text file that maps each source | |
|
33 | commit author to a destination commit author. It is handy for source SCMs | |
|
34 | that use unix logins to identify authors (eg: CVS). One line per author | |
|
35 | mapping and the line format is: | |
|
36 | srcauthor=whatever string you want | |
|
37 | ||
|
38 | The filemap is a file that allows filtering and remapping of files | |
|
39 | and directories. Comment lines start with '#'. Each line can | |
|
40 | contain one of the following directives: | |
|
41 | ||
|
42 | include path/to/file | |
|
43 | ||
|
44 | exclude path/to/file | |
|
45 | ||
|
46 | rename from/file to/file | |
|
47 | ||
|
48 | The 'include' directive causes a file, or all files under a | |
|
49 | directory, to be included in the destination repository. The | |
|
50 | 'exclude' directive causes files or directories to be omitted. | |
|
51 | The 'rename' directive renames a file or directory. To rename | |
|
52 | from a subdirectory into the root of the repository, use '.' as | |
|
53 | the path to rename to. | |
|
