Re: [Factor-talk] sequences and the stack
Aha! How could I rewrite for-all? so that it prints the first stack that fails the predicate?

The most straightforward thing I can think of is to package up the generated
values with outputsequence, then feed the array to the predicate via
inputsequence:
:: for-all ( generator: ( -- ..a ) predicate: ( ..a -- ? ) -- ? )
1000 iota [ drop
generator { } outputsequence : generated
generated predicate inputsequence : ok?
ok? [ generated . ] unless
ok? not
] find drop not ; inline

[Factor-talk] Relative vocab roots
Here's a patch to have the vocab loader save Factor's initial current directory at startup time and use it as the base for relative vocab roots such as .. That way, the program changing the current directory as part of its normal operation won't affect the vocab loader. https://github.com/jckarter/factor/commit/dc619acbfc4ba4b6f2c6d0ff93f909ff718881b5 Is this a good approach? Will this break anything? -Joe smime.p7s Description: S/MIME cryptographic signature -- EMC VNX: the world's simplest storage, starting under $10K The only unified storage solution that offers unified management Up to 160% more powerful than alternatives and 25% more efficient.

Re: [Factor-talk] Relative vocab roots
Hi Joe, This looks good. I assume you tested it :-) My only objection is the name vocab-base-directory. Is there a better name for this?

I'm not crazy about the name either, but I couldn't think of anything better. My other choice was initial-current-directory, but I wasn't sure if that adequately described the variable's purpose. -Joe smime.p7s Description: S/MIME cryptographic signature -- EMC VNX: the world's simplest storage, starting under $10K The only unified storage solution that offers unified management Up to 160% more powerful than alternatives and 25% more efficient.
