2009-03-27 LEMON joins to the COIN-OR initiative |
|
2 |
|
|
3 |
COIN-OR (Computational Infrastructure for Operations Research, |
|
4 |
http://www.coin-or.org) project is an initiative to spur the |

* Graph -> Digraph, UGraph -> Graph |
11 | 18 |
* Edge -> Arc, UEdge -> Edge |
12 | 19 |
* source(UEdge)/target(UEdge) -> u(Edge)/v(Edge) |
13 | 20 |

--dry-run|-n |
286 | 291 |
Check the files, but do not modify them. |

--interactive|-i |
288 | 293 |
If --dry-run is specified and the checker emits warnings, |
289 | 294 |
then the user is asked if the warnings should be considered |
290 | 295 |
errors. |
291 | 296 |
--werror|-w |
292 | 297 |
Make all warnings into errors. |
293 | 298 |
--all|-a |
294 | 299 |
Check all source files in the repository. |
295 | 300 |
--modified|-m |
296 | 301 |
Check only the modified (and new) source files. This option is |
297 | 302 |
useful to check the modification before making a commit. |
298 | 303 |
--changed|-c |
299 | 304 |
Check only the changed source files compared to the parent(s) of |
300 | 305 |
the current hg node. This option is useful as hg hook script. |
301 | 306 |
To automatically check all your changes before making a commit, |
302 | 307 |
add the following section to the appropriate .hg/hgrc file. |
