Question marks in a query don't match number of arguments lint check #220

geralt-encore · 2017-11-12T16:27:11Z

This is my first lint check so I am not sure if I've covered all the cases. I was using Timber lint checks as a reference. I'll appreciate any feedback!

JakeWharton · 2017-11-21T20:59:44Z

Thanks! I'll take a look soon here. If you're feeling generous you can rebase on the latest master for build fixes and version updates.

geralt-encore · 2017-11-22T10:24:11Z

Rebased generously :)

JakeWharton

This is great. I only have some small nits.

nit: missing space between "of" and "arguments" inside the concatenation. I would prefer it after "of" similar to the above string.

can you hoist the "arguments" word here and on the next line out to two local variables and check whether or not the respective count variable is 1. If so, make it the singular "argument" and if it's not 1 make it "arguments". It's a small detail, but an easy one to fix.

since you're using the new way of testing by using lint() you no longer need to extend from LintDetectorTest however you'll then need to use Junit4 and add the @test annotation on all of the methods

You could use the """ here with trimMargin() similiar to:

.expect(""" |res/layout/random.xml: Warning: Layout does not start with one of the following prefixes: activity_, view_, fragment_, dialog_, bottom_sheet_, adapter_item_, divider_, space_ [WrongLayoutName] |0 errors, 1 warnings """.trimMargin())

I don't know, I think that I got an idea how the function works, but I just can't make it work. Tbh, not even sure if it brings more readability than regular string concatenation in that case

This should be implementation since, in theory, future versions of lint could not be based on Kotlin and thus not have the stdlib already on the classpath.

If I mark it as implementation instead of compileOnly I have this error:

Execution failed for task :sqlbrite:prepareLintJar. Found more than one jar in the 'lintChecks' configuration. Only one file is supported. If using a separate Gradle project, make sure compilation dependencies are using compileOnly

That's... interesting. I mean it makes sense, but I guess we have to assume that lint will always contain the Kotlin stdlib as a result.

sqlbrite-lint/build.gradle

+dependencies {

@jrodbx We need both of these? Also is compileOnly correct for both?

At least in the official custom lint rule sample, they have it like that.
https://github.com/googlesamples/android-custom-lint-rules/blob/master/android-studio-3/checks/build.gradle

compileOnly is correct for both, since the runtime will provide the classes; however, good catch on the unnecessary lintChecks dependency. that's only needed when you're referencing/subclassing from the standard lint checks.

@geralt-encore it doesn't appear that you're relying on the standard lint checks, so you can remove the lintChecks dependency.

@jrodbx thanks for the explanation! Wasn't sure about this dependency
