Lambda Example Generation Tool

[Collin Fagan]

Hi Everybody,

With this talk about syntax I thought I would put together a quick tool to
help generate lambda examples.

https://sourceforge.net/projects/project-strum/files/lambda-gen.zip/download

lambda-gen takes a very simple xml syntax file and combines it with a
template to generate example lambdas. The README  file explains more but
here is the gist.

Syntax

<?xml version="1.0" encoding="ISO-8859-1"?>
<syntax name="Strawman with Colon">
  <prefix>:</prefix>
  <startParamList>(</startParamList>
  <endParamList>)</endParamList>
  <startBlock>{</startBlock>
  <endBlock>}</endBlock>
</syntax>

+

Template

/*
 * Syntax Poll Example:
 */
list.filter(<syntax.prefix><syntax.startParamList>Foo
t<syntax.endParamList><syntax.startBlock>t.length() \> 3<syntax.endBlock>)
    .map(<syntax.prefix><syntax.startParamList>Foo
t<syntax.endParamList><syntax.startBlock>t.barCount<syntax.endBlock>)
    .max();

=

Example:

/*
 * Syntax Poll Example:
 */
list.filter(:(Foo t){t.length() > 3})
    .map(:(Foo t){t.barCount})
    .max();


I've put together a number of different syntax files for the strawman, BGGA
and others. That said, it is a simple tool meant for experimentation and
syntax comparison only.

I have a few examples already in the template. I would be happy to add more
if people think they have a good use case.

Enjoy,

Collin
