<lloda>where does and=> come from? shouldn't it handle > 1 args like and does?

<nalaginrut>lloda: well, it's unrelated to > it's a product like symbol =>, (and=> x func) means (if x (func x))

<nalaginrut>(if x (func x) #f)

<lloda>i meant, is there some standard to respect or something? I kinda expected (and=> a b c proc) to work too

<lloda>something else, I have a string and a list of separators, is there a function to tokenize? I tried string-split but that throws away the separators, (string-split "hello.x+(bye)" (string->char-set ".+()")) -> '("hello" "x" "" "bye" "") and I'd like -> '("hello" "." "x" "+" "(" "bye" ")")

<nalaginrut>seems you need pipe-line

<nalaginrut>hmm...let me see

*nalaginrut is trying to solve this with compose

<lloda>thanks. but don't bother if it isn't very simple, I can always do a loop...

<nalaginrut>I think it could be a generic method, so it's cool to find it ou

<nalaginrut>out

<lloda>yeah...

<nalaginrut>anyway, it's easy to use fold I think

<nalaginrut>lloda: alright, I think I made a new high-order-function for that, seems useful as a generic way ;-)

*nalaginrut has the ability to make simple things complicated

<nalaginrut>lloda: https://gist.github.com/NalaGinrut/4ddc9839683bd4c9aff4

*nalaginrut has a new post idea for blog now~

<nalaginrut>hmm...shouldn't be parser, it's lexer...

<lloda>lexer, yes

<lloda>I was reading intros to parsing and they all say ---your input is already tokenized, then... :p

<lloda>but thanks a lot

<lloda>(parser "hello(,99)abc" "(),") -> ERROR: In procedure string: Wrong type (expecting character): #<eof>

<lloda>am i calling it wrong?

<nalaginrut>hmm...seems a bug?

<nalaginrut>well, I should check EOF in lexer function

<nalaginrut>anyway, the k function is generic high order function, and the pred checks exit condition

<nalaginrut>ah, I see, it's a bug in tokenizer

<nalaginrut>lloda: fixed https://gist.github.com/NalaGinrut/4ddc9839683bd4c9aff4

<nalaginrut>anyway, it's users duty to check in the customized r function

<lloda>thanks, this seems useful enough to go in a library

<nalaginrut>I'll post to blog for detailed discuss, and consider what cases can be solved with this high order function

<nalaginrut>I don't know if there's a one before

***brendyyn is now known as brendyn

<lloda>there's also string-tokenize, but it does (string-tokenize "hello(abc+xyz*a)" char-set:letter+digit) -> '("hello" "abc" "xyz" "a")...

<lloda>what do people use to tokenize?

<jmd>What is the license of guile?

<lloda>LGPL v3

<dsmith-work>Morning Greetings, Guileers

<civodul>congrats, sneek :-)

<janneke>how do i get guile to enter the debugger upon error?

<davexunit>janneke: call-with-error-handling

<davexunit>in the (system repl error-handling) module

***wleslie is now known as w5e

<janneke>davexunit: thanks, i remember something like (debug 'debugger)

***w5e is now known as v3e

***v3e is now known as wleslie
