--------- I am trying to write a little script which checks on the disk for a file to be written, then read the values and uses in a xpresso network. I am starting now. First task is check that the file is there or not. First trouble, the code I am writing does not work. this is it:
> main() \> { \> \> var filename = ("test.txt"); \> \> var a = FALSE; \> while ( a == FALSE){ \> println("the file is not there"); \> //something is wrong here: \> a = GeFileExist(filename, FALSE); \> //what is it? \> } \> \> println("Now the file IS there"); \> } \>
main() \> { \> \> var filename = ("test.txt"); \> \> var a = FALSE; \> while ( a == FALSE){ \> println("the file is not there"); \> //something is wrong here: \> a = GeFileExist(filename, FALSE); \> //what is it? \> } \> \> println("Now the file IS there"); \> } \>
I am sure it's a simple thing but I am not yet familiar with coffee. Could you help me? Thanks G>

If this is in an expression, it won't work as COFFEE Expressions cannot do any form of file system access (for security reasons). The way to go then is to create a COFFEE plugin (say, a CommandData plugin).
Also, realize that the Filename 'filename' should be a full path. Relative paths don't work ... or may only refer to the current working directory set up by Cinema 4D - that is, the Cinema 4D install folder (you'll have to check this).

thanks, would be the plugin accessible through the xpresso interface? what ultimately I am looking for is: and external applications generates a string of values in a file. Cinema is open and checks for the file to be written. As soon as the file changes the file is read and values fired in a xpresso network, which is used to simplify parametric modelling... is this possible at all?
If I write a COFEE plugin, would this be a module in the xpresso network or something else?
Thanks again G.

I don't think this is possible in COFFEE.

so shall I use C++? or is it not possible at all?
rui_mac wrote an expresso block which reads and writes texts... it was on a magazine in 2005... unfortunately the code is encrypt...
would it be possible, by having such an xpresso block, to say something like: if the frame is [0], look for this file, if the file exist read and if not keep looking for it, take values and do something, start again.
please help :-)
thanks G.
