If you hover over a child, you'd see dashed line to the left that outlines the span.

types of fusion

  • Thermonuclear fusion
  • Inertial confinement fusion
  • Inertial electrostatic confinement
  • Beam-beam or beam-target fusion

regular child 2

Nuclear fission of heavy elements was discovered on December 17, 1938 by German Otto Hahn and his assistant Fritz Strassmann, and explained theoretically in January 1939 by Lise Meitner and her nephew Otto Robert Frisch. Frisch named the process by analogy with biological fission of living cells. For heavy nuclides, it is an exothermic reaction which can release large amounts of energy both as electromagnetic radiation and as kinetic energy of the fragments (heating the bulk material where fission takes place). In order for fission to produce energy, the total binding energy of the resulting elements must be more negative (greater binding energy) than that of the starting element.

intrapage link to a future heading

That way you know you'd encounter linked item later on the page if you just keep reading.

Perhaps that's better to handle this via browser extension, then it'd work on all pages.

code exports (org-babel)

python

This is a code block:

a = "whatever"

Separate code block, but they are sharing a 'session', so the following block has access to a.

print(a)
whatever

Custom language (mypy as an example)

Custom mypy executor that runs both code and mypy

def whatever(s: str) -> int:
    return s + 1
Mypy output [exit code 1]:
input.py: note: In function "whatever":
input.py:2: error: Returning Any from function declared to return
"int"  [no-any-return]
        return s + 1
        ^
input.py:2: error: Unsupported operand types for + ("str" and "int")
 [operator]
        return s + 1
                   ^
Found 2 errors in 1 file (checked 1 source file)

TODO [2019-10-24 15:26] eh, need to implement proper eval for it somehow..

modifying Babel execution context

Set variables in Elisp code (remember to use :exports both):

;; perhaps more useful: (setenv "PATH" (concat "WHATEVER" ":" (getenv "PATH"))))
(setenv "BABEL" "yes")
yes

Use them in the code blocks in the rest of the document:

import os
print("Babel? ", os.environ['BABEL'])
Babel?  yes

After that, you can reference this table.

Again, compile-org.el is using some custom code for meaningful ids.
