Longer term, I wonder whether our DSL syntax is too weak?
Even the ability to declare blocks would be nicer than long lines
(and line split markers):-
I'd rather see us progress go a constraint and data driven
templating system. I'll discuss it more with you when we meet up.
The DSLs are just sentence templates and we needmore than that.
So what? Leave the current DSL with all its deficiencies and bugs?
DSLs are just template fragments, with any luck we can figure out how
they can fit into the larger picture of a more constrained and validated
approach.
We haven't planned anything yet, so really don't know. I just know that
pure fragment templates, with no constraints no data driven suggestions,
no validation is not an ideal long term approach.
Also being OSS nothing ever dies as long as someone is out there using
stuff and producing patches for it.

Currently each entry must be a single line of text. This
results in long lines, especially on the RHS.
I have experimentally inserted a transformation of the DSL
text (in DSLTokenizedMappingFile)
which converts '\'+EOL on the fly to a space. (The passed-in
reader is read into a buffer, '\'+EOL
is translated to space, and EOLs are inserted later to
readjust the line number.) In a text editor,
I can now write, e.g.,
then][][Bb]ook the customer for the flight=\
$f.setAvailable( $f.getAvailable() - 1 );\
update( $f ); \
Booking booking = new Booking(); \
booking.setCustomer( $r.getCustomer() ); \
booking.setFlight( $f ); \
insert( booking );
Of course, the DSL editor will not preserve this, but future
development might provide more
convenient editing there, too.
Any objections?
