Hi,
I have a simple sw-description file like this:
software =
{
version = "1.0.0"
embedded-script = "
swupdate.warn(\"new version: \" .. version)
"
...
}
I would like to access the version field inside the Lua script, but all my attempts have failed. Could someone point me to documentation or an example that describes how to do this?
Thank you in advance,
Thank you in advance,

Version is exposed by SWUpdate:
embedded-script = "
require('swupdate')
swupdate.warn(\"new version: \" .. swupdate.getversion)
"

embedded-script = "
require('swupdate')
swupdate.warn(\"new version: \" .. swupdate.getversion)
"

It returns the swupdate's version (2024.0), not the content of the `version` field in sw-description (in my example 1.0.0).

There is currently no access to global attributes (like "version"). It
is not a big deal to add it, but it is currently unsupported. Versions
are likely managed by the core, and there wasn't yet a use case to add
an interface here.

Yes, you're right, I misunderstood.
