Update tslint to the latest version 🚀

[greenkeeper]

Version 4.1.0 of tslint just got published.

Dependency	tslint
Current Version	3.15.1
Type	devDependency

The version 4.1.0 is not covered by your current version range.

Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of tslint.
Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.

Release Notes

v5.0.0

🔥 Breaking changes

• Minimum version of TypeScript version is now 2.1.0 (#2425)
• The severity level of rules are now configurable and defaults to severity "error". This affects the output of formatters:
  • [formatter] msbuild was outputting all failures as "warning".
  • [formatter] pmd was outputting all failures as priority 1. Now, it uses priority 3 for "error" (default) and priority 4 for "warning"
• [formatter] json changed the fix property to now contain either one replacement or an array of replacements (#2403)
• tslint:recommended configuration updated with tslint:latest rules & options (#2424)
• Removed no-unused-new rule, with logic moved into no-unused-expression (#2269)
• no-trailing-whitespace now checks template strings by default. Use the new options ignore-template-strings to restore the old behavior. (#2359)

API breaks for custom rules

• Removed method skip from RuleWalker (#2313)

• Removed all use of the TypeScript Language Service, use only Program APIs instead (#2235)

  • This means that some rules that previously worked without the type checker now require it. This includes:

    • no-unused-variable
    • no-use-before-declare

  • This breaks custom rule compilation. If your rule was not using the ts.LanguageService APIs, the migration is quite simple:

  - public applyWithProgram(srcFile: ts.SourceFile, langSvc: ts.LanguageService): Lint.RuleFailure[] {
  -     return this.applyWithWalker(new Walker(srcFile, this.getOptions(), langSvc.getProgram()));
  + public applyWithProgram(srcFile: ts.SourceFile, program: ts.Program): Lint.RuleFailure[] {
  +     return this.applyWithWalker(new Walker(srcFile, this.getOptions(), program));

  • N.B. If you are refactoring your custom rules, consider these performance tips for writing custom rules.

• Removed createFix. Replacements should be passed directly into addFailure. (#2403)

• Removed deprecated scanAllTokens and skippableTokenAwareRuleWalker (#2370)

🎉 Notable features & enhancements

• [feature] The severity level of rules are now individually configurable. Default severity can also be configured. (#629, #345)

  • Valid values for severity: default | error | warn | warning | none | off
  • Valid values for defaultSeverity: error | warn | warning | none | off
  • Old style:

  {
      "extends": "tslint:latest",
      "rules": {
          "callable-types": true,
          "max-line-length": [true, 140]
      }
  }

  • New style (in this example, callable-types outputs errors and max-line-length outputs warnings):

  {
      "extends": "tslint:latest",
      "defaultSeverity": "error",
      "rules": {
          "callable-types": true,
          "max-line-length": {
              "options": 140,
              "severity": "warning"
          }
      }

Version 5.9.0 just got published.

Update to this version instead 🚀

Release Notes

v5.9.0

⚠️ Deprecations

• [deprecation] Several utility functions from src/language/utils.ts have been deprecated (#3476)
• [deprecation] Linting non-existent files now outputs a warning. This will be an error in TSLint 6. (#3313)

Configuration inheritance changes

Significant changes have been made to configuration inheritance to address a long-standing UX issue around defualtSeverity: #2569.

defaultSeverity defined in a tslint.json file will now override the defaultSeverity value defined in any configurations you are extending.
This means that any rules specified in the base configurations can now take on a new defaultSeverity if you so choose. If you extend multiple
configuration files, the defaultSeverity defined in the last one wins.

In practice, this allows users to, for example, more easily use the built-in TSLint configurations (tslint:recommended, tslint:latest, tslint:all)
and treat all errors as warnings instead of errors.

For more details, see the relevant PRs:

• Override defaultSeverity defined in extended configs (#3449)
• Inherit defaultSeverity and apply it to preceding base configs (#3530)
