From cfe14bf11096ded649b57e2532302321044d51c6 Mon Sep 17 00:00:00 2001 From: Tomas Volf <~@wolfsden.cz> Date: Sat, 13 Jan 2024 14:18:04 +0100 Subject: edit: Add geiser-insert-actual-lambda. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some projects use λ, some use lambda, and it is convenient to be able to use the same mapping engraved into muscle memory for both. Therefore this commit adds a new variable that allow geiser-insert-lambda to do both, depending on the value. * elisp/geiser-edit.el (geiser-insert-actual-lambda): New variable.
