Version of cargo installed fj-app says "unreleased"

[hannobraun]

You can install a crates.io release of fj-app like this: cargo install fj-app

If you then run fj-app --version, it says something like this:

fj-app 0.20.0 (unreleased)

Official release binaries built by the release automation don't say "unreleased". This is controlled by setting an environment variable:
https://github.com/hannobraun/Fornjot/blob/49d3ac0d3795ccc20403e322c56e59570bc32e86/.github/workflows/cd.yml#L14-L16

While it makes sense to distinguish these official binaries from user-compiled ones, the "unreleased" here is confusing.

The version is currently controlled by fj-app's build.rs. Maybe it can be adapted to detect cargo install and create a more informative version string in that case? If not, maybe "unreleased" can be replaced with something more informative.

This issue is no longer up-to-date. This is the output now (as of #1367):

$ fj-app --version
fj-app 0.28.0 (development build)

It would be nice to somehow note that the binary was cargo installed, but that doesn't seem practical. At least I could find no way to get access to that information in build.rs.

In any case, even though the version output is far from perfect, this specific issue has been addressed. Closing.
