>From bdb68585d5b0ddf5a6c9876028b5f2be2f17e66a Mon Sep 17 00:00:00 2001 From: Aaron Ecay Date: Wed, 10 Feb 2016 19:39:04 +0000 Subject: [PATCH] ob-core: remove cruft MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * lisp/ob-core.el (org-babel-execute-src-block): Simplify. (org-babel-tramp-handle-call-process-region): Remove. Commit 57104f9f changed an org-flet to a let, rendering the whole apparatus of modifying call-process-region inoperative. Supposedly this was put in place to work around a bug in tramp-handle-call-process-region, which was removed from tramp in 2012 (after being renamed tramp-sh-call-process-region). *shrug* This commit just removes the whole thing. It also no longer consults ‘org-src-lang-modes’, which is not helpful here. --- lisp/ob-core.el | 133 ++++++++++++++++++++------------------------------------ 1 file changed, 47 insertions(+), 86 deletions(-) diff --git a/lisp/ob-core.el b/lisp/ob-core.el index 025985d..77f464f 100644 --- a/lisp/ob-core.el +++ b/lisp/ob-core.el @@ -26,6 +26,7 @@ (eval-when-compile (require 'cl)) (require 'cl-lib) +(require 'subr-x) ; For `if-let' (require 'ob-eval) (require 'org-macs) (require 'org-compat) @@ -36,10 +37,8 @@ nil)) ;; dynamically scoped for tramp -(defvar org-babel-call-process-region-original nil) (defvar org-babel-library-of-babel) (defvar org-edit-src-content-indentation) -(defvar org-src-lang-modes) (declare-function outline-show-all "outline" ()) (declare-function org-get-indentation "org" (&optional line)) @@ -679,72 +678,53 @@ block."
