Felix has a new feature. Using this file:
/////// xx.flx /////////////////
#import <nugram.flxh>
open syntax felix;
////////////////////////////////
and this command (on Unix ..)
bin/flxp --document-grammar -Ilib xx
then point your browser at
misc/gramdoc/index.html
This is (supposed to be) a fully cross-referenced specification
of the Felix grammar. For example misc/gramdoc/stype_constraint.html:
stype_constraint :=
| epsilon
| with squalified_name_comma_list
| where sexpr
| where sexpr with squalified_name_comma_list
| with squalified_name_comma_list where sexpr
Currently, the productions for a non-terminal are all listed,
no matter which DSSL they're from. Might be worth specifying
the DSSL. There's an index of all nonterminals. DSSL's aren't
listed.
The idea here is to add 'documentary text' which will also
print: that text might be embedded in the grammar spec.
It's clear more of the 'meta' productions (such as ?+* etc)
need to be used to reduce the number of 'spurious' nonterminals.
Also, with one page for each nonteminal, some coherence is
lost that might arise if related non-terminals are listed
together.
