I'd prefer to use a generic library like reqs there and just have the check for the maximum requirement there. Michal do you have any preference ? FWIW I had originally written the reqs library for for rel-html [0] which enables arbitrary projects to make a shiny HTLM5 release project based on a naked release page provided, the inferring of release needs some generic heuristics on release matching (in the future the simpler

This is when spatch --cocci_version is passed ? Its still unclear how we can require in a clean way coccinelle version requirements in SmPL patches with this. Can you clarify? If we embrace this or assume we'll get this in the next release we'll have to just bump the kernel's coccinelle requirement recommendation, which I think is far due anyway.

I'm not sure that being backward compatible with older versions of Coccinelle is worth adding new libraries to the Linux kernel, and adding unpleasant python code to semantic patches. The above ocaml code just produces eg 1.0.5 or 1.0.5-dirty.

But surely if spatch --version-only was available we'd use that instead a well. Other than this though how can we require coccinelle version checks per SmPL file cleanly and also what should we do to make it backward compatible with older versions of coccinelle?

This lets one annotate version requirements and is backward compatible. Luis ___ Cocci mailing list Cocci@systeme.lip6.fr https://systeme.lip6.fr/mailman/listinfo/cocci

How about the following, since Coccinelle knows what its version is? This could of course be implemented in python as well. julia diff --git a/docs/Coccilib.3cocci b/docs/Coccilib.3cocci index 0e4fbb8..ca5b061 100644 --- a/docs/Coccilib.3cocci +++ b/docs/Coccilib.3cocci @@ -232,6 +232,15 @@ is the empty list if spatch is not currently working on any file (eg, in an initialize or finalize rule). .sp +.I val cocci_version +: +.B unit -> string +.sp +Returns the a string indicating the current version.
