Hi all!
I am not sure I understood this fully, but I understand that I could
create a parser in J so that I could write explicit J code and get a
tacit result. I just want it included in the J language.
As we can see here, Jpp addresses another tacit J problem with the
'double/multi adverbs' extension:
https://github.com/Pascal-J/jpp
This problem is not that visible if not most of your code is chains of
conjunctions, like in tacit J.
Cheers,

quotes is the essence of any dsl, but you/we want to avoid the tedium of
escaping quotes at many levels.
in jpp, this expression contains an explicit definition within another
x + (+: y bb. 3.. y bb. 4..
4 : 'x + ''+: y'' bb ( 3 : ) y'
x + (+: y bb. 3.. y bb. 4../2 3
'x + ''+: y'' bb ( 3 : ) y' bb ( 4 : ) / 2 3
8
the remaining bb is harmless, though a better dsl parser might tunnel into the
dsl definition looking for specific sub-dsl definitions that is relevant to it.
Basically if you can make a tacit-v adverb that takes a string as parameter
(called say TV), then jpp lets you integrate it into J code with auto-quoting
and auto-paren balancing by calling it with TV. , or if it were a verb TV:
quotes is the right delimiter compared to {} (due to existing J meaning of
those). Its a matter of reducing the annoyance of quotes IMO. It looks like
you want to compile your t-v expressions into J code, and jpp is suited for
this too.

Subject: [Jprogramming] Tacit Expressions with Explicit J Syntax
Hi all !
I entered a request for tacit expressions with explicit J syntax.
http://code.jsoftware.com/wiki/System/Interpreter/Requests#Tacit_expressions_with_explicit_J_syntax
I use J only for fun so I am not going to finance development, but maybe
others want to. As I see it it would solve most of the problems we
struggle with daily since 20 years or something.
Cheers,
