问题 I'm trying to capture the output of diff with org-babel, but for some reason it's not working. For the files 1 a b c 2 a c b diff 1 2 called from the command line returns 1c1 < a b c --- > a c b But with org-babel, nothing: #+begin_src sh diff 1 2 #+end_src #+RESULTS: The minibuffer reads "Code block produced no output". The org-babel error output window is empty. Other commands such as ls show the output as expected. I'm not familiar with org-babel. I tried using :results output verbatim ,

问题 Consider the following snippet of perl in org-babel, which uses <STDIN> . ** Ans 2 #+begin_src perl :results output use Math::Trig; $rad = <STDIN>; $circumference = 2*pi*$rad; print "Circumference of circle is $circumference"; #+end_src Is it possible to pipe the input to this block from another block ? Say : #+begin_src text :name test-input 12.5 #+end_src 回答1: You can pass $rad directly to the perl script from a #+results block : see passing arguments to code blocks in the manual. That

问题 In Orgmode, is there a way to tangle just the blocks in subtree matching (or not matching) a specific tag ? For instance with the following code * A #+BEGIN_SRC c printf("Not exported"); #+END_SRC * B :D: #+BEGIN_SRC c printf("Exported"); #+END_SRC exporting along tag D , the tangle C file will only contains printf("Exported"); I'm using org-mode to organise my emacs config, and my goal is to derive different configs from the master one emacs-config.org . (for instance a lightconfig by

问题 I want to know about my networking hardware. lspci | grep -i net From the terminal, this command gives the following output: 00:19.0 Ethernet controller: Intel Corporation 82577LM Gigabit Network Connection (rev 06) 02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35) But when I try running this from org-mode through a babel source block I get no output. #+BEGIN_SRC sh lspci | grep -i net #+END_SRC #+RESULTS: What gives? How can I get the same output I got from the

问题 I have an org file with lots of babel source blocks in it that only need to be re-executed when the code is changed. How do I prevent org from executing all of the blocks during export? In other words, set them all to manual execution only? I would prefer a single global option rather than having to edit each block individually. 回答1: The variable org-export-babel-evaluate , if set to nil , will prevent any code from being evaluated as part of the export process. This way, only the results
