JSHint VS Checkstyle

jshint -> Old library

also, if you are going to code for this sheet and do not know about the website jshint.com, you need to know about jshint.com

There is an error in some file. Or maybe some wine shenanigans (never used it). You can try searching for the file item-possessionLimit.js and paste it into something like https://jshint.com/ to get an analysis and try to fix it. But it might give you further errors or file might be packed somewhere.

If you are coding for this sheet and you do not know about jshint.com ...

JSHint

I came across a problem where I had to find the ES6 features used by any javascript project and other data regarding their use. When I reached out to stackoverflow, I could find only one relevant post which asks you to use linters like jshint/jshint or compilers like babel. Jslint didn't seem to report anything specific to ES6 and Babel converts all the ES6+ features to ES5 but doesn't report anything regarding which constructs were used or how many times they were used. However, Jshint reported all ES6 features used in the code along with some metadata. And, to suit my needs, I ended up writing a python script that calls Jshint on all JS files in a project and presents the features used in the project and the number of times they were used across all files. You can find the code here : jsHintRunner

Javascript Linting parses and checks if any syntax is violating the rule. If a violation occurs, a warning is shown explaining unexpected behavior. Use the online version for small projects: JSLint, ESLint or JSHint. For larger projects, it is recommended to use a task runner like Gulp or Grunt. Linters ensure developers are following the best practices as a result of which few bugs appear during project development.

If you don't know https://jshint.com/ and want to script for this sheet, then you should know https://jshint.com/

If you don't know it, you should: jshint.com That website has saved me a few headaches.

Did you try jshint.com ?

I'm trying to use Google's checkstyle. I want certain things to be an error, such as using Tabs for indentation. When I run mvn checkstyle:check with a file with a tab in the first column, it always gives a [WARN] rather than the error that I've asked for. Pom snippet: org.apache.maven.plugins maven-surefire-plugin ${maven-surefire-plugin.version} ${maven-surefire-plugin.skipUnitTests} org.apache.maven.plugins maven-checkstyle-plugin 3.1.2 checkstyle validate check google_checks.xml UTF-8 true true warning true I'm using google_checks.xml as from https://github.com/checkstyle/checkstyle/blob/master/src/main/resources/google_checks.xml. I have changed the severity for the FileTabCharacter to "error"

1. Conflicts between Spotless and Checkstyle Checkstyle is a tool for checking Java source code for compliance with code standards or a set of validation rules (best practices).

Never had anything like that though for four years my life revolved around getting PMD, checkstyle and Sonar rules to pass so my pull request would merge.

PMD, and checkstyle as well.

I’m a little out of date with Java, but I believe Checkstyle is currently popular: https://github.com/checkstyle/checkstyle

Another example can be applied to code quality itself. Most static analyzers are configurable. If you tried to set Checkstyle Google configuration to the mature project, you would probably get hundreds or even thousands of errors. You can start with just one rule. Ar first glance, it seems not so important. But after the moment when the configuration reaches the repository, you can be sure that no one else can violate this rule in the future.

Checkstyle: a tool that helps programmers write Java code that adheres to a coding standard: https://github.com/checkstyle/checkstyle

So I was there once, sharing my solution. For my current project I use the java formatter jar, but on my previous work I was using checkstyle, you can get it from here: Checkstyle. Then pass your checkstyle xml format config.
