Convert very simple markdown syntax to very simple pseudo-code.

Code markdown is line-oriented whereas pseudo-code is structure-oriented (braces indicate inclusion).

Basic Premise

Use markdown-mode of emacs to write code and elide details.

Elision in Emacs Org-Mode

Position mouse over a line containing an octothorpe #.

Press TAB key.

This will open/close a layer.

Pressing TAB key again and again will toggle between elided and non-elided forms of the text.

Italicized Identifiers

Possible convention, italicized identifiers can include spaces (but not underscores - this can be changed later to be some other character or sequence) and are considered to be comments.

Example

Input

# _containment_

## _fb pipeline_
	allContains1
	printAllDeepContains
	printAllDirectContains



## _details_
### allContains1
	load fb
	load onSameDiagram
	load contain1
### printAllDeepContains
	load fb
	load onSameDiagram
	load contains2
### printAllDirectContains
	load fb
	load onSameDiagram
	load contains3

Output

{_containment_

{_fb pipeline_
	allContains1
	printAllDeepContains
	printAllDirectContains



}
{_details_
{allContains1
	load fb
	load onSameDiagram
	load contain1
}
{printAllDeepContains
	load fb
	load onSameDiagram
	load contains2
}
{printAllDirectContains
	load fb
	load onSameDiagram
	load contains3
}}}

Algorithm

A section beginning with an octothorpe # is composed of 3 parts:

The octothorpe #
The first text up to \n
The rest of the text up to the next octothorpe (incl. \n’s).

# a b 
## c d
## e f

is converted to

{ a b { c d } { e f }}

using a simple algorithm, see md2brace.html and support.js.

Set two counters to 0. (depth and openbrackets).
When a # is encountered, determine new depth as the number of #s. If newdepth > depth, emit an open brace {, if newdepth === depth emit close and open }\n{, otherwise panic. Set depth to newdepth, increment openbrackets by number of { that were added.
At the end, emit one ‘}’ for each openbracket.

No judgement is made about the contents of a,b,c,d,e,f. (That is left up to other tools).
