[Pkg-javascript-devel] Bug#1026974: Cannot exclude a component from consideration using !

[Julian Gilbey]

Package: pkg-js-tools
Version: 0.15.12
Severity: normal

I am working on a package (node-webfont) which requires a non-node
component.  The dh-nodejs tools keeps complaining, for example
debclean reports:

Found debian/nodejs/additional_components
/!\ woff2/package.json not found
Unable to load woff2 
/!\ brotli/package.json not found
Unable to load brotli 

My additional_components reads:
---
!brotli
!woff2
---
following the guidance in pkg-js-tools(7), if I've understood it
correctly.  But it seems that this syntax doesn't help;
list-node-components reports:

[...]
varstream
woff2
brotli
!brotli
!woff2

with the first occurrence being picked up from debian/watch and the !
occurrences being those in additional_components.  But
component_list in /usr/share/perl5/Debian/PkgJs/Utils.pm has a
different behaviour, and it would seem that that should work.
Unfortunately, though, it doesn't appear to do so, and I don't
understand why not.

Best wishes,

   Julian
