Linting your project

Linting is the process of statically analyzing code to find code style violations and to detect errors. cookietemple implements a custom linting system, but depending on the template external tools linting tools may additionally be called.

cookietemple’s linting is divided into three distinct phases.

All linting functions, which all templates share are called and the results are collected.
Template specific linting functions are invoked and the results are appended to the results of phase 1

The linting results of the first two phases are assigned into 3 groups:

Passed
Passed with warning
Failed

If any of the checks failed linting stops and returns an error code.

Linting example — Linting applied to a newly created cli-java project.

To examine the reason for a failed linting test please follow the URL. All reasons are explained in the section Linting codes.

Usage

cookietemple lint can be invoked on an existing project using

$ cookietemple lint <PATH>

PATH [CWD]: The relative path to the project directory.

Flags

Linting codes

The following error numbers correspond to errors found during linting. If you are not sure why a specific linting error has occured you may find more information using the respective error code.

General

general-1

File not found. This error occurs when your project does not include all of cookietemple’s files, which all templates share.

Please create the file and populate it with appropriate values. You should also critically reflect why it is missing, since at the time of the project creation using cookietemple this file should not have been missing!

general-2

Dockerfile invalid. This error usually originates from empty Dockerfiles or missing FROM statements.

general-3

TODO string found. The origin of this error are COOKIETEMPLE TODO: or TODO COOKIETEMPLE: strings in the respective files. Usually, they point to things that should be manually configured or require other attention. You may remove them if there is no task for you to be solved.

general-4

Cookiecutter string found. This error occurs if something went wrong at the project creation stage. After a project has been created using cookietemple there should not be any jinja2 syntax statements left. Web development templates may pose exceptions. However, {{ *cookiecutter* }} statements should definitely not be present anymore.

general-5

Versions not consistent. If the version of all files specified in the [bumpversion] sections defined in the qube.cfg file are not consistent, this error may be found. Please ensure that the version is consistent! If you need to exclude specific lines from this check please consult Bumping the version of an existing project. To prevent this error you should only increase the version of your project using cookietemple bump-version.

general-6

changelog.rst invalid. The changelog.rst file requires that every changelog section has a header with the version and the corresponding release date. The version above another changelog section should always be greater than the section below (e.g. 1.1.0 above 1.0.0). Every section must have the headings **Added**, **Fixed**, **Dependencies** and **Deprecated**.

general-7

cookietemple.cfg linting failed. The cookietemple.cfg plays a major role in cookietemple’s sync and bump-version functionality.

The linter ensures that following requirements are met:

1.) Every config file should have at least the following sections: bumpversion, bumpversion_files_whitelisted, bumpversion_files_blacklisted, sync_files_blacklisted, sync_level

2.) bumpversion should only contain a current_version value (the project’s current version)

3.) bumpversion_files_whitelisted should contain at least the .cookietemple.yml file in the dot_cookietemple variable

4.) sync_level should only contain a ct_sync_level value (and this value should be one of either patch, minor or major)

5.) sync_files_blacklisted should contain at least the CHANGELOG.rst file (excluding it from syncing to avoid PR updates)

6.) sync should only contain a sync_enabled value (and this value should be one of either True|true|Yes|yes|Y|y|False|false|No|no|N|n)

cli-python

cli-python-1

File not found. This error occurs when your project does not include all of cli-python’s expected files.

Please create the file and populate it with appropriate values. You should also critically reflect why it is missing, since at the time of the project creation using cookietemple this file should not have been missing!

cli-python-2

PyPI dependency not up to date. The dependencies specified in the requirements.txt and requirements_dev.txt are not up to date.

It is up to you whether you can and want to update them.

cli-python-3

The cookietemple.cfg section called sync_files_blacklisted misses either requirements = requirements.txt, requirements_dev = requirements_dev.txt or changelog = CHANGELOG.rst. All are required to exclude them from syncing and interference with services like dependabot.

cli-java

cli-java-1

File not found. This error occurs when your project does not include all of cli-java’s expected files.

Please create the file and populate it with appropriate values. You should also critically reflect why it is missing, since at the time of the project creation using cookietemple this file should not have been missing!

cli-java-2

The cookietemple.cfg section called sync_files_blacklisted misses build_gradle = gradle.build or changelog = CHANGELOG.rst. Both are required to exclude the gradle build file from syncing.

lib-cpp

lib-cpp-1

File not found. This error occurs when your project does not include all of lib-cpp’s expected files.

Please create the file and populate it with appropriate values. You should also critically reflect why it is missing, since at the time of the project creation using cookietemple this file should not have been missing!

lib-cpp-2

The cookietemple.cfg section called sync_files_blacklisted misses changelog = CHANGELOG.rst. This is required to be excluded from syncing.

web-python

web-python-1

File not found. This error occurs when your project does not include all of web-python’s expected files.

Please create the file and populate it with appropriate values. You should also critically reflect why it is missing, since at the time of the project creation using cookietemple this file should not have been missing!

web-python-2

The cookietemple.cfg section called sync_files_blacklisted misses either requirements = requirements.txt, requirements_dev = requirements_dev.txt or changelog = CHANGELOG.rst. All are required to exclude them from syncing and interference with services like dependabot.

gui-java

gui-java-1

File not found. This error occurs when your project does not include all of gui-java’s expected files.
