Subject: Can el-search-query-replace replace mapcar with --map ?
Date: Fri, 22 Dec 2017 19:45:07 +0800	[thread overview]
Message-ID: <m21sjn6l6k.fsf@xuchunyang.me> (raw)

Hi.

'C-h P el-search' mentions 'el-search-query-replace' can replace 'mapc'
with 'dolist'. I would like to know if it is also possible to replace
'mapcar' with '--map' (from dash.el), for example, change

  (mapcar (lambda (x) (* x x)) '(1 2 3))

into

  (--map (* it it) '(1 2 3))

I have tried:

   M-x el-search-query-replace RET
   `(mapcar (lambda (,val) . ,body) ,list) -> `(--map ,@body ,list) RET

It gives me:

  (--map
   (* x x)
   '(1 2 3))

it is almost right except the variable name, '--map' only knows 'it',
not 'x'.

Any suggestion?

Thanks.
