Say I want to write about the count of my system’s processors at the time of my writing. Or my current location’s weather or stock shares or …use your imagination. Now I do it like that:

> At this very moment I’m writing this text on a machine with 4 processors.

Verbatim:

At this very moment I'm writing this text on a machine with src_bash{cat /proc/cpuinfo | grep processor | wc -l} processors.

Practically I expand a snippet, write any bash command into the curly braces and instantly have it’s evaluated result written into my prose.

Python example

Inline

Two plus two equals 4

Verbatim: > Two plus two equals src_python{return(2+2)} {{{results(=4=)}}}

Code block

Expand any code block’s result as well: 12

Verbatim: > Expand any [[python_example][code block]]'s result as well: call_python_example()

 #+name: python_example
 #+begin_src python
 def func():
     return 1+1+2+3+5

 return func()
 #+end_src
