Derive name for `const` and `forEach` from expression

Hey! I have awesome idea to derive variable names for builtin const and forEach snippets.

const

Improve variable name for const, let (and var?) snippets.

I simply use regexs to derive const name from expression.

We can use the part after get|read|create|retrieve|select|modify|update|use

Some examples:

someObject.getUser().const         ; const user = someObject.getUser()
// react or vue
useRouter().const                  ; const router = useRouter()
fs.readFile().const                ; const file = fs.readFile()
await updateRect(...anyArgs).const ; const rect = await updateRect(...anyArgs)

UPDATE: special handling of expression starting with new:

• just lowercase variable (if class starts with uppercase)

const mutationObserver = new MutationObserver().const

forEach

Also for forof snippet.

Just use singular form of last part of expression (if appliable).

1. Skip if identifier doesn’t end with s or sList (or just List?)
2. Remove List part if appliable
3. Use pluralize with count 1 to get singular form

Example:

cookies.forEach(cookie => )

I’m using it for a while and can say its pretty neat.

Anyway I think it’s much better than just name or item variables that should be renamed in 99% cases.

What do you think? Should we make this behaviour disableable?

Some of the postfixes could probably be implemented this way

You’re right! I’d make it work in the web, reduce ext size (and probably parsing time, as it’d reuse sourcefiles). I think I’m going to give more details in https://github.com/ipatalas/vscode-postfix-ts/issues/13 within a few days.

it’s more effort to install a TS plugin than VSCode extension (which you do only once, not per workspace). Do you have this plugin released officially or still WIP?

Of course! You can look at repository URL. I’m using it on daily bases (also that’s why I don’t use webstorm anymore).

Actually I don’t have plugin published, because for now it’s not possible to install it in some workspace, because it relies on the extension itself. This is primarily a VSCode extension, that as you said you install only once.

No, its just disabled by default: "editor.suggest.preview": true
