I am reading a text file into an array. I would have expected the array size to grow to the same as the number of lines/elements in the text file but it seems to default to a size of 100. Is there a way for the size of the array to take on the size of the text file automatically? If not how do I get the number of lines in the text file so I can resize the array accordingly?
Thanks,
Jim
Hi Jim,
Like [soundfiler]’s “-resize” flag, this would be a very useful feature for array loading.
You can load a text file and then query its size, something like:
[read -c your_file, bang(
|
[text]
|
[text size]
|
[array size your_array]

Hmm, not sure this patch will work fine. Did you try it ?
Jim, What do you want to store in the array. That doesn't seem entirely clear to me ? Do you need to store each character ? [array]s, in Pd, only store floats. So you will be able to store each character as its decimal ASCII representation (or maybe better to use Unicode here) in the array. For instance, "A" will be 65. ++

Hi Jack,
Well, yes, it was something ‘like’ that.
here it is with the missing [t b p] and [text size -s text t]

OK, thanks. Nice example using pointer. On My side, I used to use [text define] (to load the text file) and [text size] (to query the size with a 'bang' message). ++

So you will be able to store each character as its decimal ASCII representation (or maybe better to use Unicode here) in the array. For instance, "A" will be 65.
Even simpler in Pd (instead of unicode), use directly 'UTF8' encodage to store a character as number in an array. For instance, 'Ɲ' will be store as '198 157'. With [list tosymbol], you can get back the right character. ++
