ECMAScript Explicit Resource Management & using Declarations #52955
Description
Activity
Does this one accept PRs? Happy to work on this.
I have already started this effort, but thanks for the interest!
I'm hoping we shouldn't have the same kind of conflict in the future given that
DisposableStackis the name of built-in class related to this feature. You generally don't perform other operations generically on a disposable like you do for iterators.https://github.com/tc39/proposal-async-explicit-resource-management is stage 3 (see tc39/proposals) and it's planned to merge it back with sync version of proposal so could you update this issue and 5.1 iteration plan?
Reacted by Toni Villena
Ron Buckton (@rbuckton)'s proposal for Explicit Resource Management has reached stage 3 in TC39!
As such, it's time for TypeScript to look into its implementation. This proposal carries a few new features that TypeScript should have
usingdeclarationsSymbol.disposeSuppressedErrorIterator.prototype[Symbol.dispose]Disposable(which I think we should consider callingDisposableLike)DisposableStackWe are in a slightly weird spot here since downlevel emit of
usingis possible, but will require alibofesnext.Given that the 5.1 timeframe will be shorter, it would be reasonable for our first stab at this feature to include only support for
--target esnext.Note that since Async Explicit Resource Management has been split off into its own proposal, I'm not suggesting we add it here.
