composer update edgedesign/phpqa:dev-phpmetrics-config

[cbastienbaron]

@zdenekdrahos seems has no effect

#.phpqa.yml
phpmetrics:
    config: .phpmetrics.yml

#.phpmetrics.yml
default:
    rules:
        cyclomaticComplexity: [ 10, 6, 2 ]
        maintainabilityIndex: [ 0, 75, 95 ]

    failure: average.maintainabilityIndex < 1  or sum.loc > 10

[phpqa] No failed tools

Hint: don't know if behaviour is expected but if i put

#.phpqa.yml
phpmetrics:
    config: .noexist.yml

i have no errors / exceptions :)

@cbastienbaron: you have to specify 0 in --tools. Take a look at change in bin/ci.sh.

phpqa --tools phpmetrics:0

When allowed errors cell is empty, it means that errors weren't analyzed.

It's optional feature that is by default turned off. You have to define number of allowed errors
