direct string comparision?

hi -

is there any chance to come to a direct string comparision with the new
parser?
for instance:

<CsoundSynthesizer>
<CsInstruments>
instr cmp
if "a" == "a" then
prints "well done\n"
endif
endin
</CsInstruments>
<CsScore>
i "cmp" 0 1
</CsScore>
</CsoundSynthesizer>

instead of:

<CsoundSynthesizer>
<CsInstruments>
instr cmp
i_a strcmp "a", "a"
if i_a == 0 then
prints "well done\n"
endif
endin
</CsInstruments>
<CsScore>
i "cmp" 0 1
</CsScore>
</CsoundSynthesizer>

(which is very clumsy if there are many comparisions)

thanks -

joachim

Re: direct string comparision?

With 6 lines of code I have

instr 1
if strcmp("foo", "foo") == 0 then
prints "well done ?\n"
else
prints "noooooooooooooo\n"
endif

print strcmp("foo", "foo")
print strcmp("foo", "bar")
printk2 strcmpk("foo", "foo")
printk2 strcmpk("foo", "bar")
endin

...
new alloc for instr 1:
well done ?
instr 1: #i1 = 0.000
instr 1: #i2 = 1.000
i1 0.00000
i1 1.00000
...

Is it useful ?

Re: direct string comparision?

It is not possible to use the same name for the func
and the opcode. We have to find a name for the string functions
related to strcmp and strcmpk. Ideas?

hmm ...
in hannover, i understood from something john was saying, that one
benefit of the new parser can be to allow a more functional syntax.
so i am not sure if it is wise to add some functions now. perhaps it is
better to wait until the new feature is possible, and many opcodes can
be written as opcode(arg1, arg2)?

Re: direct string comparision?

the only difference between func and opcode is the syntax

For example, with a new strcmp??? function, a new symbol is added only.
Internally, the function becomes the strcmp opcode.

Re: direct string comparision?

Question for all: is it worth adding new functions, or is it better to
wait and try to get the parser to allow calling opcodes as functions?

If the syntax `strcmp???(Str)' is obsolete before being born,
it's not to add. Then we should make the accounts with
the compatibility of the code.

If the syntax is useful and forever, it's to add

It might be easier to implement == as an operator between strings as
originally suggested.

I had thought about this solution (in yacc) but is `==' irate or krate ?

About the functions, I think that a good alias is forever.
If today I write a function `foo()' as an alias for the foobarbazquux
opcode, because it's short and many users find it useful, it's to add.
In an only-opcode-wolrd it's simple to add an alias for the
foobarbazquux opcode. Therefore, I think that to add a function is not
a problem if we see it like an alias.

It's a no-fear post and only the opinion of the
my left neuron (the other doesn't know csound)
