1. Is there a way to adjust the 80 char line break limit?
2. When I?m using a python script that parses a token that crosses multiple lines for some reason the output gets merged onto a single line:
- printk(" Min latency from hw interrupt up to 'C' int. "
- "handler:"
- " %d tcs = %d nsec\n",
+ printk(" Min latency from hw interrupt up to 'C' int. " "handler:" " %lu tcs = %lu nsec\n?,
Is there something I should be doing special?
I?m using a modified version of Johann?s script for adjusting printf formatters:

Currently, it's a non-modifiable configuration variable. I can add a flag
for it.

I think that it would be difficult to do anything about this. The string
passes through python and gets modified, and then gets dumped back into
the code in the end. At that point, Coccinelle just sees it as one atomic
unit. Does the issue come up a lot?

That would be useful.

A fair amount for the code base I?m working on (Zephyr - https://www.zephyrproject.org). What?s interesting is this seems to bypass the line length check/breaking.

For parsing Zephyr, the main issue seems to be the __IO annotation. You
can take the existing standard.h, copy it to eg zephyr.h and add
#define __IO
then when you run Coccinelle, put --macro-file-builtins zephyr.h
You should also be able to put at the root of the zephyr directory a file
.cocciconfig
[spatch]
options = --macro-file-builtins zephyr.h
Or rather the complete path for zephyr.h. Then this file will always be
used when you run Coccinelle on code in the zephyr directory.

You can pull this from github. --max-width n

Thanks Julia!
This is helpful for my Wine work where the preferred line length is 100.
I just kept forgetting to ask for it.
