Complexity - 3

vscode-tslint is now supporting:

• The status of the TSLint linter is now shown in the status line.
• Ther tslint.nodePath setting enables to load tslint from a different location than the current workspace or the globally installed npm modules`.
• Added command to create an initial tslint.json file.

Set up

• Side install the latest vscode-tslint
  • git clone https://github.com/Microsoft/vscode-tslint
  • cd vscode-tslint
  • Run npm install on both folders "tslint" and "tslint-server"
  • In the "tslint" folder run vsce package -> produces tslint-0.5.40.vsix
  • code-insiders --install-extension tslint-0.5.40.vsix
• Note that the tslint module has a peer dependency on the typescript module, therefore you must install both tslint and typescript to enable vscode-tslint.

Test

• Without having tslint and typescript installed try to lint a .ts file. Create a tslint.json file using the command palette.
  • Verify that the status bar item shows an error and the output channel shows the reason.
• Install tslint and the typescript once locally and globally
  • Verify that you get warnings from tslint
• Use the setting tslint.nodepath to install tslint and typescript into another location
• Create an error in the tslint.json file. There are two different error situations:
  • a syntax error in the JSON file, then tslint doesn't attempt to lint
  • a misspelled rule name, this is detect at run-time only
  • Verify that the status item indicates an error in both cases. Clicking the status bar item opens the output channel.
