oelint-adv 1.8.0

Advanced bitbake-recipe linter

Advanced oelint

Purpose

Based on the OpenEmbedded Styleguide and work done by oe-stylize-tool this module offers a (nearly) complete linter for bitbake-recipes.

The tool does handle includes/requires automatically so you don’t have to pass them via CLI.

NOTE: .bbappend-files have to be passed via CLI - these are NOT gathered automatically

Install

With pip

pip3 install oelint_adv

From Arch Linux:

yay -S oelint-adv

Usage

oelint-adv
usage: __main__.py [-h] [--suppress SUPPRESS] [--output OUTPUT] [--fix]
                   [--nobackup] [--addrules ADDRULES [ADDRULES ...]]
                   files [files ...]

Advanced OELint - Check bitbake recipes against OECore styleguide

positional arguments:
  files                 File to parse

optional arguments:
  -h, --help            show this help message and exit
  --suppress SUPPRESS   Rules to suppress
  --output OUTPUT       Where to flush the findings (default: stderr)
  --fix                 Automatically try to fix the issues
  --nobackup            Don't create backup file when auto fixing
  --addrules ADDRULES [ADDRULES ...]
                        Additional non-default rulessets to add

Output

Will be [file]:[line]:[severity]:[message].

Example:

/disk/meta-some/cppcheck-native/cppcheck.inc:26:error:oelint.task.nomkdir:'mkdir' shall not be used in do_install. Use 'install'
/disk/meta-some/cppcheck-native/cppcheck-native_1.87.bb:0:error:oelint.var.mandatoryvar:Variable 'SECTION' should be set

/disk/meta-some/cppcheck-native/cppcheck.inc:26:error:oelint.task.nocopy:'cp' shall not be used in do_install. Use 'install'
/disk/meta-some/cppcheck-native/cppcheck.inc:12:warning:oelint.var.order:'DEPENDS' should be placed before 'inherit'

Apply automatic fixing

Some of the rules are capable of fixing the issues found automatically. This will be done if you pass –fix as a startup parameter.

As long as you don’t pass –nobackup a backup copy (filename + .bak) will be created for all files fixed.

These rules are sometimes contrary to OE-style-guide, so use them with caution

jetm ruleset

To enable pass –addrules jetm to CLI
