[Parseperl-discuss] [Introduction] About myself

[Jeffrey G. <dr...@po...>]

As near as I can remember I've been writing Perl since...'96 or so. 
Since then I've written a few articles for O'Reilly and managed the 
first few Parrot releases after Simon passed on the torch. More to the 
point, I've been fiddling with a pure-Perl vim-style editor for some 
months in Curses and POE.

Once I've gotten a visual mode done (or have given up and hacked 
vim+perlinterp sufficently) I'd like to see (for instance, I've got 
other ideas) a ':Makesub' macro come out of this, that takes a block of 
code, picks out the free variables and creates a 'sub foo { my 
($free_1,$free_2) = @_; my @internal_array = @$free_2; 
code_block_here() }' text block in a separate buffer that they can 
paste into another file and replace the original code block with a call 
to the procedure.

Of course, other transforms and, more importantly, the ability to 
perform dataflow tracing on code to determine whether a given variable 
is free or bound have to precede this. I've tried writing some simpler 
transforms, but these were with early versions of PPI, and if I 
remember, walking the internal data structures (which was required, as 
there weren't splicing operations that worked) was fraught with some 
peril.

In any case, with the new release I'll go back and revisit the old 
code, and hopefully make things work.
