Added codeRepr and dumpCode to the macros module.

[PMunch]

This allows those writing macros to write examples, get the code to generate the AST for that example, and then modify that code to be dynamic with the macro function.

[Araq]

DRY.

[PMunch]

Dry?

[Araq]

Line too long.

[Araq]

Add a test case please, but the code bloat bothers me.

In what way is this different to echo toStrLit(node)?

[PMunch]

@dom96 echo toStrLit(node) outputs the code represented by that node. codeRepr creates the code to generate the AST. An example:

toStrLitMacro:
  echo "Hello world"

outputs:

echo "Hello world"

dumpCode:
  echo "Hello world"

outputs:

nnkStmtList.newTree(
  nnkCommand.newTree(
    newIdentNode(!"echo"),
    newLit("Hello world")
  )
)

As you can see dumpCode outputs code you can put into your macro to generate the code you give it. This is helpful as you can write up an example output, then run dumpCode on it and copy the contents into your macro while editing in the macro logic.

[dom96]

I see. It should get a different name then (dumpCodeGen?), and the docs need to have this explanation.

[PMunch]

Hmm, a different name sure is possible. But not sure what you mean by the docs, I've tried to explain what it does in the doc-strings added to the file. If you have another wording I'd be happy to change it!

[dom96]

I mean: show what this produces, just like you've shown above.

[PMunch]

Something like that?

[Araq]

Add a test case please.
