|
281 | 14 | """Convert a foreign SCM repository to a Mercurial one. |
|
282 | 15 | |
|
283 | 16 | Accepted source formats: |
|
284 | 17 | - Mercurial |
|
285 | 18 | - CVS |
|
286 | 19 | - Darcs |
|
287 | 20 | - git |
|
288 | 21 | - Subversion |
|
289 | 22 | |
|
290 | 23 | Accepted destination formats: |
|
291 | 24 | - Mercurial |
|
292 | 25 | - Subversion (history on branches is not preserved) |
|
293 | 26 | |
|
294 | 27 | If no revision is given, all revisions will be converted. Otherwise, |
|
295 | 28 | convert will only import up to the named revision (given in a format |
|
296 | 29 | understood by the source). |
|
297 | 30 | |
|
298 | 31 | If no destination directory name is specified, it defaults to the |
|
299 | 32 | basename of the source with '-hg' appended. If the destination |
|
300 | 33 | repository doesn't exist, it will be created. |
|
301 | 34 | |
|
302 | 35 | If <MAPFILE> isn't given, it will be put in a default location |
|
303 | 36 | (<dest>/.hg/shamap by default). The <MAPFILE> is a simple text |
|
304 | 37 | file that maps each source commit ID to the destination ID for |
|
305 | 38 | that revision, like so: |
|
306 | 39 | <source ID> <destination ID> |
|
307 | 40 | |
|
308 | 41 | If the file doesn't exist, it's automatically created. It's updated |
|
309 | 42 | on each commit copied, so convert-repo can be interrupted and can |
|
310 | 43 | be run repeatedly to copy new commits. |
|
311 | 44 | |
|
312 | 45 | The [username mapping] file is a simple text file that maps each source |
|
313 | 46 | commit author to a destination commit author. It is handy for source SCMs |
|
314 | 47 | that use unix logins to identify authors (eg: CVS). One line per author |
|
315 | 48 | mapping and the line format is: |
|
316 | 49 | srcauthor=whatever string you want |
|
317 | 50 | |
|
318 | 51 | The filemap is a file that allows filtering and remapping of files |
|
319 | 52 | and directories. Comment lines start with '#'. Each line can |
|
320 | 53 | contain one of the following directives: |
|
321 | 54 | |
|
322 | 55 | include path/to/file |
|
323 | 56 | |
|
324 | 57 | exclude path/to/file |
|
325 | 58 | |
|
326 | 59 | rename from/file to/file |
|
327 | 60 | |
|
328 | 61 | The 'include' directive causes a file, or all files under a |
|
329 | 62 | directory, to be included in the destination repository, and the |
|
330 | 63 | exclusion of all other files and dirs not explicitely included. |
|
331 | 64 | The 'exclude' directive causes files or directories to be omitted. |
|
332 | 65 | The 'rename' directive renames a file or directory. To rename from a |
|
333 | 66 | subdirectory into the root of the repository, use '.' as the path to |
|
334 | 67 | rename to. |

281 | """Convert a foreign SCM repository to a Mercurial one. | |
|
282 | ||
|
283 | Accepted source formats: | |
|
284 | - Mercurial | |
|
285 | - CVS | |
|
286 | - Darcs | |
|
287 | - git | |
|
288 | - Subversion | |
|
289 | ||
|
290 | Accepted destination formats: | |
|
291 | - Mercurial | |
|
292 | - Subversion (history on branches is not preserved) | |
|
293 | ||
|
294 | If no revision is given, all revisions will be converted. Otherwise, | |
|
295 | convert will only import up to the named revision (given in a format | |
|
296 | understood by the source). | |
|
297 | ||
|
298 | If no destination directory name is specified, it defaults to the | |
|
299 | basename of the source with '-hg' appended. If the destination | |
|
300 | repository doesn't exist, it will be created. | |
|
301 | ||
|
302 | If <MAPFILE> isn't given, it will be put in a default location | |
|
303 | (<dest>/.hg/shamap by default). The <MAPFILE> is a simple text | |
|
304 | file that maps each source commit ID to the destination ID for | |
|
305 | that revision, like so: | |
|
306 | <source ID> <destination ID> | |
|
307 | ||
|
308 | If the file doesn't exist, it's automatically created. It's updated | |
|
309 | on each commit copied, so convert-repo can be interrupted and can | |
|
310 | be run repeatedly to copy new commits. | |
|
311 | ||
|
312 | The [username mapping] file is a simple text file that maps each source | |
|
313 | commit author to a destination commit author. It is handy for source SCMs | |
|
314 | that use unix logins to identify authors (eg: CVS). One line per author | |
|
315 | mapping and the line format is: | |
|
316 | srcauthor=whatever string you want | |
|
317 | ||
|
318 | The filemap is a file that allows filtering and remapping of files | |
|
319 | and directories. Comment lines start with '#'. Each line can | |
|
320 | contain one of the following directives: | |
|
321 | ||
|
322 | include path/to/file | |
|
323 | ||
|
324 | exclude path/to/file | |
|
325 | ||
|
326 | rename from/file to/file | |
|
327 | ||
|
328 | The 'include' directive causes a file, or all files under a | |
|
329 | directory, to be included in the destination repository, and the | |
|
330 | exclusion of all other files and dirs not explicitely included. | |
|
331 | The 'exclude' directive causes files or directories to be omitted. | |
|
332 | The 'rename' directive renames a file or directory. To rename from a | |
|
333 | subdirectory into the root of the repository, use '.' as the path to | |
|
334 | rename to. | |
