Rewriting POSIX prefixes in JSON files on Windows? #1788
Description
As always, thanks for rattler-build!
I'm trying to update ipykernel-feedstock to use rattler-build.
On Windows, I'm seeing a bad path coming from a build-time JSON file, deployed into $PREFIX/share, which also references $PREFIX, but fully resolved. To be encoded in JSON, the windows-style slashes get escaped.
Our old technique of replacing the peril-fraught \ (or, worse, \\) with / to avoid JSON issues is not working.
Without digging into the code, this looks like perhaps either or both of:
- the POSIX-style
$PREFIX(with/) is not sought - the Redmond-style
%PREFIX%(with\\) is not sought
