LOOK here if you are doing something in the Listener and having issues
in your file, set them with set-global, instead of set
Anything set with set will get lost when the top level expressions finish evaluating since files are parsed inside a with-scope
The only way to change the listener's search path is by entering USING:, USE:, etc in the listener
the first time, USE: will load the vocabulary, but any USE: or USING: in the source file that gets loaded will not affect the listener
slava: methods don't belong to a vocabulary
slava: methods belong to a generic word
slava: to invoke a generic word, you have to have the generic word's vocabulary in your search path
metaperl: I think that might trip up a lot of people
slava: well, its how java import statements owrk
slava: it only affects the source file being parsed
slava: I guess python and ruby just stick everything in one global namespace
slava: so you load a source file which loads another source file and suddently you've got 30 new identifiers in the global scope, some of which clash with your existing ones :)
If you just want to reload the source file, do refresh-all in the listener
you don't have to restart it
slava: 5 1 swap 3 3array
slava: or 5 :> x { 1 x 3 }
slava: prunedtree would suggest something like 5 1array { 1 } { 3 } surround [ ] map
Notwithstanding Gertm's suggestion that you should write them with luck, you can have tests assert that the result is a string, of the right length, etc.
How about seed-random? Don't use that word. But you can do this:
1234 <mersenne-twister> [ ... ] with-random
Now a sequence of calls to 'random' will produce the same results every time inside the quotation.
=== If I were going to create a series of vocabularies based around text, is there hierarchy support? e.g. text.lorem, text.leetspeak, text.balanced
or should they have just underscores in their name? textlorem ===
there's hierarchy support. USE: foo.bar
loads foo/bar/bar.factor
