Webcast – BAML – A DSL for BAM

I never really “got” the idea of the need to build a textual DSL when I was first introduced to MGrammar. The light really switched on when I looked into developing a DSL that would make it easier for developers to create BAM activities.

The BAML language only took a couple of hours to develop. I had experimented with simple text based DSLs before, so this was my first “real” language.

I have recorded a 20 minute webcast showing how the language works, and how it can be used. If you want to experiment with it yourself, the language is here.

language BAML

{

syntax Main = Activity;

syntax Activity =

ActivityToken

n:NameToken

'{'

p:List(PKI)

'}'

=> { activity { n,{ p }} };

syntax PKI = Milestone | Integer | Decimal | Text;

syntax Milestone = t:MilestoneToken n:NameToken ';'

=> { t, { n } };

syntax Integer = t:IntegerToken n:NameToken ';'

=> { t, { n } };

syntax Decimal = t:DecimalToken n:NameToken ';'

=> { t, { n } };

syntax Text = t:TextToken n:NameToken ';'

=> { t, { n } };

syntax List (Element) =

e:Element => { e } |

list:List(Element) e:Element => { valuesof(list), e };

token NameToken = ('A'..'Z' | 'a'..'z')+;
