Make use of trailing semicolons optional

[demisx]

Many programmers are no longer using a semicolon to terminate code lines in languages where it's optional. Our team doesn't use trailing ; when programming in TypeScript and/or JavaScript. However, when Intellisense inserts a line, it automatically terminates it with ;. Would be really helpful if the option whether to end each line with a semicolon or not was configurable globally per language. Then, Intellisense and other plugins could honor it to make one's coding more efficient.

• VSCode Version: 1.18.1
• OS Version: macOS High Sierra 10.13.1

Steps to Reproduce:

1. Remove import statement for an existing type
2. Accept Intellisense suggestion to add import statement
3. When import is added a ; is auto added at the end of the line

Reproduces without extensions: Yes

Can you please explain what specific action is triggering the semicolon to be inserted?

[demisx]

Sure. It's just as I wrote in the description pretty much:

1. Let's say I write this line where IAd is a new type:

const ad: IAd = ctx.request.body

1. The TypeScript Intellisense kicks in and suggests me to import it, i.e.
   

2. I accept the suggestion and this is what's added to the import block. Note the trailing ;

import IAd from './ad.interface';

I'd like to be able to instruct VS Code that I don't use ending semicolons in some language, e.g. TypeScript, JavaScript etc. And then have Intellisense, plugins, snippets to honor that setting. Currently, I have to take care of the semicolons myself and that makes coding less efficient.

Hope this helps. Please let me know if you need more info.

Thanks for the additional info. This falls under microsoft/TypeScript#18780 and microsoft/TypeScript#19882

Using the TSlint workaround from the SO question may help for now: https://stackoverflow.com/a/47667384/306149

@mjbvz Thanks. Will those cover other languages (besides TypeScript) that also have ; optional?

[mjbvz]

Yes, those issues apply to both JavaScript and TypeScript. The TypeScript project is what provides our JS language support
