(This is going to be cool. I'm totally geeked out about Oslo and I want me some Textual DSL goodness)
((Also, I have approx 51 mins of battery left so I might have to leave early.)
MGrammar is actually a DSL over MGraph the lowest level of M
We will be implmenting a grammar to parse: "Contact: giodl - 555-1212"
Inside of IntelliPad there will be 3 panes
- Left is the input
- Center is the Grammar
- Right is Output
- Errors are listed on the bottom
Module is the top level Container for MGrammar
Language is the top level structure "Think void main"
token == word
syntax == sentence
Range expressions is ".."
How to model whitespace?
- Explicitly model wherever we want it
- OR "interleave"
You can use single or double quotes
Step 1 in creating a DSL is tokenizing
Step 2 is parsing
Step 3 is shaping
FYI, this is mostly a demo based presentation so it's hard to make good notes. Go watch this online.
