From ee08934a649b4a6c14d8b2ee1c24f849621284a9 Mon Sep 17 00:00:00 2001 From: Joseph Novakovich Date: Mon, 31 Aug 2020 10:14:15 -0400 Subject: [PATCH] ob-J.el: Add ability to customize sit duration * lisp/ob-J.el (org-babel-execute:J, org-babel-J-eval-string): Add customizability. (org-babel-execute:J): Lookup optional parameter `:sit' to allow one to wait for a specified amount of time before grabbing the output of the J subprocess. Pass this specified value or the previous default of .1 to `org-babel-J-eval-string'. (org-babel-eval-string): Pass new argument `sit-time' to `sit-for' before grabbing output. The problem is that we read the contents of the output after 0.1 seconds, which, for expensive computations, results in the mangling of output. Output from expensive computations gets propagated down to subsequent code-blocks' outputs, producing a horrible mess.
