Re: [Factor-talk] Saving the definitions in the scratchpad vocabulary

[John Benediktsson]

Hi Joan,

That looks handy.

The "scratchpad" vocabulary is persisted in the image, so if you ``save``,
then exit and restart Factor, all the words you had defined will be
available.

Your technique looks fine, only thing I might add is a newline for spacing
between definitions and maybe sort them alphabetically instead of randomly,
and to fix mutually recursive definitions potentially being ordered wrong,
we DEFER: all words first.

: dump-words ( vocab path -- )
utf8 [
vocab-words [ name>> ] sort-with
[ "IN: scratchpad" print [ "DEFER: " write name>> print ] each
nl ]
[ [ see nl ] each ] bi
] with-file-writer ;

To save a vocab's words:

 "scratchpad" "~/dump.factor" dump-words

To restore your words from a file:

"~/dump.factor" parse-file

You'll probably get some "Already using ``...`` vocabulary" warnings,
because each definitions is "complete" and that saving code doesn't
aggregate the using list for all definitions that are being persisted.  We
could work some better code to do that if you care.

Best,
John.

Re: [Factor-talk] Saving the definitions in the scratchpad vocabulary

[Joan Arnaldich]

That "dump-words" word is enough for my needs most of the time. If I ever
need to improve on that (eg. by factoring out the "USE:") , I think I could
do that myself by looking at the implementation of "see" in the browser...

Thanks a lot! :)
