* [Cocci] Fixing SmPL scripts for data output according to structured file formats @ 2019-11-08 12:15 Markus Elfring 2019-11-08 12:51 ` Julia Lawall 0 siblings, 1 reply; 3+ messages in thread From: Markus Elfring @ 2019-11-08 12:15 UTC (permalink / raw) To: Coccinelle Hello, I have taken another look at a script for the semantic patch language. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/scripts/coccinelle/free/iounmap.cocci?id=cd0207a7bfd29016a4eeb0b0203fa900b41e4eee It belongs to the category of SmPL scripts which support data output also for structured file formats. The output order matters then for the integration of additional information so that preferably valid data are provided at appropriate places. A well-known file format like “Org mode” expects then that specific contents should be enclosed by corresponding tags. https://orgmode.org/manual/Literal-Examples.html But a SmPL rule which uses the SmPL asterisk functionality triggers immediate output of diff hunks so far (if a source code fragment was matched). I find such a data processing approach questionable for this operation mode. I imagine the following solution possibilities. 1. Separate SmPL rules should be used without SmPL asterisks. 2. It would occasionally be more convenient to redirect the output to standard files into corresponding variables. How would you like to improve the software situation here?

Thanks for your reminder on this command option. How do you think about to look at possibilities around the redirection of output to files so that diff hunks from matched source code fragments (according to SmPL asterisk functionality) could be directly used from corresponding variables?
