Auto format DML?

[Deron Eriksson <de...@gmail.com>]

Hi,

I experimented with Atom's Beautify to see if I could automatically format
DML using their R format.

Since DML is quite similar to R, I found that making a few minor tweaks to
DML made it possible to run DML scripts through the R formatter.

DML vs R syntax differences (there may be more):
1) DML has input parameters preceded by $
2) DML has parfor
3) DML for/parfor can take unrecognized parameters such as "check=0"
4) DML functions can return multiple values
5) DML function signatures are different from R
6) certain # comments at the end of lines seem to produce
%InLiNe_IdEnTiFiEr% errors using Beautify

Does anyone happen to know if there's a way that DML could be automatically
formatted (using any tool) without needing to tweak the DML before/after
formatting due to the syntax differences?

BTW I took a look at this because currently our DML format is only defined
as having 2-space indentations (see
http://apache.github.io/systemml/contributing-to-systemml#dml-code-format),
and it would be nice if we had a standard format that could automatically
be applied to DML using a tool.
