Makefile Linting: By language target

Bulk sandbox linting
Make Target	Description
help \| grpe lint	Display available help for lint targets and flags.
make lint	Invoke all source linters, linting is conditional by language.

Language and tool specific linting targets
lint-{topic}-help	Display extended help for a topic, supported targets and flags, etc.
lint-{topic}-all	Lint everything available by file extension.
lint-{topic}-mod	Lint locally modified files (git ls-files -m \| lint)
lint-{topic}-src	Lint a list of files passed in (make lint-{topic}-src VAR=list-of-files)

All Sources

The generic lint target can be used to invoke all defined lint targets.

make clean
make lint 2>&1 | tee log

Makefile help

Individual Makefiles support a help target that will display a list of targets and functionality supported.

make help
make help | grep {topic}

help
Make Target	Description
help	Display available help for targets and flags
make help \| lint-{topic}	Display summary usage for lint-doc8, lint-license, lint-make
lint-{topic}-help	Display extended help for a topic, supported makefile targets, etc

Legacy Help Usage

make help
make help-verbose
make help VERBOSE=1

doc8 / restructuredText (rst)

Command: doc8

Makefile Targets
Target	Description
help	Display item `lint-doc8` as a summary help topic item.
lint-doc8-help	Display extended help for `lint-doc8` targets

lint-doc8	Build system lint target used to syntax check restructuredText sources.
lint-doc8-all	Filesystem traversal, check all `*.rst` sources.
lint-doc8-mod	Syntax check locally modified files (~git status)
lint-doc8-src	Syntax check a list of files passed in as an argument.

lint-doc8-install	Dependency driven installation of the doc8 tool.

make clean
make lint-doc8 2>&1 | tee log

Sources
Source	Description

Include repository URL
Include gerrit/github changeset if available.

Repositories

Notes

Volume problem reports require cleanup before linting can become a default.
- After bulk linting problems for a language source have been cleaned up default linting can be enabled by modifing {project-root}/config.mk.
Lint target support is globally available across repositories, given time it will be. Submit patches as needed or open a jira ticket to request linting support in specific repositories.
Makefile refactoring: yes absolutely! Baby steps are needed in the interim…
