Allow underscore prefix to disable no-unused-vars #1058

fiesh · 2020-02-24T08:43:20Z

If one wants to repeat a block n times, a v-for="i in n" comes in handy.

Now vue/no-unused-vars will rightfully complain that i is unused.

In TypeScript, there's a similar issue with function arguments that are not used on purpose. These are ignored as unused if prefixed with a _.

How about allowing this for no-unused-vars as well? So that v-for="_i in n" would not warn, while v-for="i in n" would.

The text was updated successfully, but these errors were encountered:

I think _ is better, which is same as other lint rule, i can provide a pr for this

okey, no-unused-var is not only contains v-for stuff, so your proposal is better, 👍
