"b")))) | (skeleton-insert `((completing-read "Input: " ',v) | "str = " str ?\n | "Output: " (cdr (assoc str ',v)) | str ?\n))) when entering/choosing "a" at prompt, the output is: | str = a | Output: b When entering "not-a", the output is: | str = not-a | Output: not-a Everything is working as expected. Now if the first line of the skeleton is removed: | (let | ((v '(("a" . "b")))) | (skeleton-insert `((completing-read "Input: " ',v) | "Output: " (cdr (assoc str ',v)) | str ?\n))) the output when entering "a" is: | Output: a The same happens if (completing-read "Input: " ',v) is re- placed by a simple "Input: ". skeleton-insert's documentation says: | […] The following local variables are | available: | str first time: read a string according to INTERACTOR | then: insert previously read string once more | […] so I can imagine that skeleton-insert gets confused by str being first used inside an expression. But what is the proper way to reliably use it "there"? TIA, Tim
