ex_check v0.5.0 mix check View Source
One task to efficiently run all code analysis & testing tools in an Elixir project.
How it works
First it runs the compiler and aborts upon compilation errors (but not warnings). Further tools
are run in parallel (unless --no-parallel
option is passed) and their output is streamed one by one for instant insight.
After all tools are completed, output from those that have failed gets reprinted for sake of easily reading into them all at once.
Finally, a summary is presented with a list of all tools that have succeeded, failed or were
skipped due to missing files or project dependencies (unless --no-skipped
option is passed).
Tools
Following curated tools are configured by default:
:compiler
- produces compilation warnings that allow to early detect bugs & typos in the code eg. an attempt to call non-existing or deprecated function:formatter
- ensures that all the code follows the same basic formatting rules such as maximum number of chars in a line or function indentation:ex_unit
- starts the application in test mode and runs all runtime tests against it (defined as test modules or embedded in docs as doctests):credo
- ensures that all the code follows a further established set of software design, consistency, readability & misc rules and conventions (still statical):sobelow
- performs security-focused static analysis mainly focused on the Phoenix framework, but also detecting vulnerable dependencies in arbitrary Mix projects:dialyzer
- performs static code analysis around type mismatches and other issues that are commonly detected by static language compilers:ex_doc
- compiles the project documentation in order to ensure that there are no issues that would make it impossible for docs to get collected and assembled
You can disable or adjust curated tools as well as add custom ones via the config file.
Configuration file
Check configuration may be adjusted with the optional .check.exs
file. Task will load the
configuration in following order:
- Default stock configuration.
.check.exs
in user home directory..check.exs
in umbrella root directory when called from sub-project..check.exs
in current project directory.
Use the mix check.gen.config
task to generate sample configuration that comes with well-commented examples to help you get started.
Command line options
--only dialyzer --only credo ...
- run only specified check(s)--except dialyzer --except credo ...
- don't run specified check(s)--no-skipped
- don't print skipped tools in summary--no-exit-status
- don't halt EVM to return non-zero exit status--no-parallel
- don't run tools in parallel
