This program checks projects versions through RSS and Atom feeds and |
|

should only print those with new release version. |

It implements checking for projects in github.com and freshcode.club. |
|
41
|
|
|
Projects must be added to a YAML file (named by default |
|
42
|
|
|
~/.config/versions/versions.yaml). One can use --file=FILENAME option |
|
43
|
|
|
to specify an alternative YAML file. version.yaml is included as an |
|
44
|
|
|
example in this project. |
|
45
|
|
|
|
|
46
|
|
|
Versions uses and produces text files. Those files are cache files |
|
47
|
|
|
written into ~/.local/versions directory. "*.cache" are cache files |
|
48
|
|
|
containing the project list and their associated version (the latest). |
|
49
|
|
|
"*.feed" are information feed cache files containing on only one line |
|
50
|
|
|
the latest parsed post of the feed. |
