This program is used to investigate how any changes inside your nixpkgs
|
||||||
|
repository may hurt. With these kind of information you may choose wisely
|
||||||
|
where you should commit your changes.
|
||||||
|
|
||||||
|
This program adapts it-self to your versionning system to avoid too much
|
||||||
|
effort on your Internet bandwidth. If you need to check more than one
|
||||||
|
commits / revisions, you may use the following commands:
|
||||||
|
|
||||||
|
--git remotes/trunk..master
|
||||||
|
--svn 17670:17677
|
||||||
|
|
||||||
|
Check the differences between each commit separating the first and the
|
||||||
|
last commit.
|
||||||
|
|
||||||
|
--path /etc/nixos/nixpkgs:/tmp/nixpkgs_1:/tmp/nixpkgs_2
|
||||||
|
|
||||||
|
Check the differences between multiple directories containing different
|
||||||
|
versions of nixpkgs.
|
||||||
|
|
||||||
|
All these options exist with one commit / revision argument. Such options
|
||||||
|
are used to compare your \$NIXPKGS path with the specified version.
|
||||||
|
|
||||||
|
If you omit to mention any other commit / revision, then your \$NIXPKGS path
|
||||||
|
is compared with its last update. This command is useful to test code from
|
||||||
|
a dirty repository.
