2016-05-08tools: lint for object literal spacingRich Trott
There has been occasional nits for spacing in object literals in PRs but the project does not lint for it and it is not always handled consistently in the existing code, even on adjacent lines of a file. This change enables a linting rule requiring no space between the key and the colon, and requiring at least one space (but allowing for more so property values can be lined up if desired) between the colon and the value. This appears to be the most common style used in the current code base. Example code the complies with lint rule: myObj = { foo: 'bar' }; Examples that do not comply with the lint rule: myObj = { foo : 'bar' }; myObj = { foo:'bar' }; PR-URL: https://github.com/nodejs/node/pull/6592 Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Brian White <mscdex@mscdex.net>

Add the following (seemingly non-controversial) ESLint rules: * `constructor-super`: Verify calls of `super()` in constructors. Flags situations that will result in runtime errors. Since we do not have 100% code coverage in tests, linting for runtime errors is useful. * `no-class-assign`: Flags cases where a class declaration is overwritten via variable assignment later. It is difficult to think of a situation where this is not an error, and easy to think of situations (particularly in lengthy test files) where it could come up. * `no-const-assign`: Assigning to a const after declaration is a runtime error. * `no-dupe-class-members`: Declare a class member twice, then only the second one counts. This is analogous to redeclaring a variable. * `no-this-before-super`: Using `this` or `super` in a derived class before a call to `super()` is a `ReferenceError` PR-URL: https://github.com/nodejs/node/pull/5210 Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Roman Reiss <me@silverwind.io> Reviewed-By: Johan Bergström <bugs@bergstroem.nu> Reviewed-By: Rod Vagg <rod@vagg.org>
