1. Printing numbers
Hi,
OK, I've only been playing with Euphoria for a couple of years, but I have
an elementary question that's driving me nuts.
I want to take a sequence of integers and turn it into a .csv file - ie a
text file with the numbers as numbers, with commas in between (and maybe
semicolons for line delimiters). No braces or anything, just numbers.
I've tried print, puts etc, and a couple of libraries in the archives, but
nothing I do seems to work.
It surely can't be that hard???
Apologies if I'm being really stupid and have missed something blindingly
obvious, but can anyone help?
TIA
Sid

Sid,
If you use Gabriel Boehme's "print.e" from the archives, it's pretty easy
(and this is why it really should be in Euphoria in the first place):
<code follows>
include print.e
sequence someNumbers
someNumbers = {1,2,3,4}
procedure someProcedure()
integer outFile
outFile = open("num.txt", "w")
for n = 1 to length(someNumbers) do
print(outFile, someNumbers[n])
if n < length(someNumbers) then
puts(outFile, ",")
end if
end for
close(outFile)
end procedure
<end code>
result is:
1,2,3,4

Not to knock Gabriel's library, but if you change the line:
> print(outFile, someNumbers[n])
into:
> printf(outFile, "%d", {someNumbers[n]})
you should get the same result, without having to use Gabriels's library.

i would have always thought that to be the logical way to print decimals
because i came from a C/C++ (not much though) background before euphoria

Here is one way of doing this...
sequence NumberList
integer FldDelim, LineDelim, Delim
FldDelim = ','
LineDelim = ';'
for i = 1 to length(NumberList) do
if i != length(NumberList) then
Delim = FldDelim
else
Delim = LineDelim
end if
printf(file, "%d%s", {NumberList[i]), Delim})
end for
