Subject: [cocci] Searching for repeated source code with SmPL?
Date: Mon, 6 May 2024 12:08:22 +0200	[thread overview]
Message-ID: <bf850b64-b4bc-4738-9086-43018b8fbe93@web.de> (raw)

Hello,

Source code parts can occasionally be repeated.

* Loops
  The control flow can contain ordinary loops.

* Recursion
  A function may be called by itself.


Such constructs trigger special consequences also for further data processing
with higher level technologies.

+ Computation tree logic

+ Linear temporal logic


I am still looking for clarifications so that the Coccinelle software
can be applied in safer ways.


Regular expressions support some search operators for quantification.
A notation is accordingly supported for the specification of a minimum number
of matches which would be bigger than one item.

I imagine that such functionality would be helpful also for the semantic patch language.
How will the chances evolve to extend corresponding quantifiers anyhow?

I would appreciate if multiple occurrences of code elements can be better detected
and transformed.

Regards,
Markus
