Bitbake.conf in isar and linting

Bitbake.conf in isar and linting

[-- Attachment #1.1: Type: text/plain, Size: 761 bytes --]

Hey,

I am wondering if a specific styleguide exists for isar? Normally for 
bitbake based projects I am using oelint-adv. 

When I played around with dpkg-raw and wanted to install some file under 
/etc, this caused the linker to complain about not using sysconfdir for etc.

Is there a specific reason why isars bitbake.conf would omit to also define 
variables got etc, bin and friends?


Best,
Simone

Hi,

let's loop Adriaan Schmidt in, as he already worked on an ISAR linter.

Well, yes and no...
Years ago I very briefly looked into technical solutions for bitbake linting (maybe it was oelint-adv, but I don't exactly remember), and how flexible/extensible those might be.
Even with that in place, it would be up to the Isar Community to actually define a style and rules, but as far as I'm aware nothing like this exists yet.

Hi I see thanks,

While oelint-adv is fairly configurable, I see another point here: Is it 
really advisable to hard code paths such as /etc, /usr/bin, bin and so on? 
I only noticed that those are hard-coded by running oelint-adv, If a distro 
(also in different versions I believe there was some switch with debian 
12(merged usr))
however handles bin usr etc differently then other it would be nice to 
configure them in variables.

We've looked at pylint but not at oelint-adv.

Ideally, we imagined our recipes as three-liners (inherit dpkg, SRC_URI, SRCREV
or similar) which wouldn't require much of style. In the (very distant) future,
we'd need automatically created recipes or even not need recipes at all (all
necessary metadata is already inside the Debian-style source packages). This
not being the case today :) , I think oelint-adv could be evaluated whether
it's useful and configurable enough for Isar. Experiences welcome.

Regarding your specific questions -- sysconfdir, etc, bin and friends -- those
vars are very OE-specific and in are in case of Isar all managed by the Debian
package building infrastructure. So my wish would be exactly about it -- if the
tool turns to be useful for Isar, we shouldn't force people to deal with many
false positives.

Other than that, seems that the tool is not intended to provide pure formatting
guidance, but also real style guidance -- in that case, I think major effort
would be needed to make it useful to check for Isar development patterns.

With kind regards,
Baurzhan

I was thinking about recipes that inherit dpkg-raw e.g. sdk-files.bb

we have ok experiences with the following config:


FILES="$(find . -name "*.conf" -o -name "*.bb*" -o -name "*.inc")"
oelint-adv \
    --suppress oelint.var.mandatoryvar.HOMEPAGE \
    --suppress oelint.var.mandatoryvar.DESCRIPTION \
    --suppress oelint.task.docstrings \
    --suppress oelint.task.heredocs \
    --suppress oelint.vars.homepageping \
    --suppress oelint.vars.mispell \
