Re: watch file for Fiji

[Soren Stoutner <soren@debian.org>]

Frederic,

Uscan needs to be able to find the file to download based on the version number 
in the debian/changelog.  So, for example, if the changelog says:

privacybrowser (0.6-1) unstable; urgency=medium

It will look for a download with version number 0.6 (uscan automatically 
removes the `-1` Debian part of the version number).

For example, here is the watch file that, paired with that changelog, can find 
the correct download.

version=4
opts=pgpsigurlmangle=s/$/.asc/ https://download.stoutner.com/privacybrowser-pc/privacybrowser-(.+).tar.xz

This is pretty easy because all of the releases are in one directory and are 
named similar to the release number.

https://download.stoutner.com/privacybrowser-pc/

Your case is more complicated, because each release in the archive you are 
referencing is stored in a separate directory based on the date.

https://downloads.imagej.net/fiji/archive/

But, it looks like the source code is available on GitHub.

https://github.com/fiji/fiji

Uscan can download release artifacts from GitHub.  For example, the following 
watch file downloads two (manually uploaded) release assets from GitHub and 
combines them into one orig.tar.xz.

# uversionmangle rewrites the binary tarball releases to sort before the 
source releases.
# For example, 3.052R becomes 3.052~R.

version=4
opts="searchmode=plain,repacksuffix=+dfsg,dversionmangle=auto,\
    filenamemangle=s%.*/v?@ANY_VERSION@%@PACKAGE@-$1.tar.gz%,\
    uversionmangle=s/(\d)((R)\d*)$/$1~$2/" \
    https://api.github.com/repos/adobe-fonts/source-sans/tags?per_page=50 \
    https://api.github.com/repos/adobe-fonts/source-sans/tarball/refs/tags/v?
@ANY_VERSION@
opts="searchmode=plain,dversionmangle=auto,component=precompiled-binary-fonts,
\
    filenamemangle=s%.*/v?@ANY_VERSION@%@PACKAGE@-$1.tar.gz%" \
    https://api.github.com/repos/adobe-fonts/source-sans/tags?per_page=50 \
    https://api.github.com/repos/adobe-fonts/source-sans/tarball/refs/tags/v?
@ANY_VERSION@R same uupdate

It looks like you might only need much simpler options.  Try using these 
instructions:

P.S.  I find `uscan -vv` (extra verbose) to be really helpful in 
troubleshooting what uscan sees when it scans for a download.
