Hi Roger,

I cast a glance at your debian/watch file. You are using a rule
provided by the original debian/watch template. Personally, I don't
really like this format because I think it is very complex. You can
watch directly the "releases" link from any GitHub project. I intend
to help you with a light format.

There are several possibilities. I will show you two solutions. The
first solution is search for one or more digits (\d+), followed by a
dot (\.), followed by any character except blank spaces (\S+). It is a
Perl Regex. See below:

version=4
https://github.com/shadowsocks/v2ray-plugin/releases
.*/archive/v?(\d+\.\S+)\.tar\.(?:bz2|gz|xz)

Note that "v" (from version) is optional (v?) and we will accept
.tar.bz2, .tar.gz and .tar.xz extensions.

Another way is downgrading all versions starting with 2019. In this
case we can use any digit followed by any character except blank
spaces (\d\S+).

version=4
opts=uversionmangle=s/2019/0.2019/ \
https://github.com/shadowsocks/v2ray-plugin/releases
.*/archive/v?(\d\S+)\.tar\.(?:bz2|gz|xz)

There are several other solutions. In your original debian/watch (I
don't like this format) you can combine the last solution.

Regards,

Eriberto
