Hi, I'm seeking for ideas/comments/experiences how to best implement a
DSL in D.
What I would like to do is something like this:
... my D code ...
my-dsl {
... my multi-line DSL code ...
trade 100 shares(x) when (time < 20:00) and timingisright()
}
... my D code ...
Some things that circle in my head:
* Can the D parser somehow be missued for a DSL? So I can skip all the
generic features for types etc.?
* I could use a PEG grammer for parsing the DSL, but this leads to
quite some overhead for a tiny DSL.
* For static DSL code I would like to use CTFE to convert it into D code
* Does this requires a CTFE compatible PEG parser tookit?
* Could I somehow call an external program during compilation which
gets the DSL block as input and returns D code?
* For dynamic DSL code I think I need to create something like an interpreter
* How can I reference D variables from DSL code? Is there a lookup
meachnisam or do I have to create a dictonary?
* Is it possible to populate such a dictonary via CTFE?
