If you need [array] or [table] to do operations on them, you could use : [text define] to load your list of float, [0( on [text size] to get the number of float in your text file.

Then use this number to resize your [array] and then load your textfile in this array.

I don't test it, and maybe there is a more elegant way to achieve this. ++

Hello Jack,

Yes [text] is great, but I'm currently using tables/arrays that I want to be stored on filesystem. I actually can [read array.txt ( containing an array (i.e. a list of floats) with [text], and the whole array is loaded as a list on first line, but I'm concerned about performance while loading/parsing data.

Then this would mean using :

[0 $1 1 ( | [text get dataAsText]

instead of :

[$1 ( | [tabread dataAsArray]

I will give this solution a try, but I'm using quite large tables (more than 10,000 float values)... do you think it's as fast as [tabread] ?

(PS : I'm also looking for a way to know if a specified file (giving its path) exists or not. I did this once with the [shell] external, but I would prefer a vanilla solution...)

have a nice day,

Raphaël

Hello Raphaël,

For textfiles ?
Maybe you should use [text] ?

Also, if the file has numbers on separate lines, you can use the "-cr" flag to the "read" message to text to get each one on its own line in the object - this should make it easier to manipulate. But "array" objects are much more efficient - it might be worth writing a loop that simply loads the numbers from text into an array one by one at startup.

OTOH the "soundfiler" object really should be able to read/write ascii numbers - that's been on my dolist for a decade or more.

I think, it is better to do : [0( on [text get] (instead of reload the text file) and send result to [array set]. ++
