String Expression Problem

[stass3d]

Hello!!!

I trying to make OTL

In OTL I`ve a File parameter

in which i have a value like this:

$HIP/cache/armour.$F.bgeo

In File node in OTL I need to set this:

$HIP/cache/armour.`trunc($FF)`.bgeo

I wrote a function:

string createFileName(string in){
    string filename = chsraw(in);
    string res = strreplace(filename, '.$F.', '.`trunc($FF)`.');
    return res;
}

If i testing this function in textport, it returns right result:

/ -> echo `createFileName("/obj/geo1/s3d_FileBlender1/File_path")`
$HIP/cache/armour.`trunc($FF)`.bgeo

But a File sop errors with a message:

Error: Unable to read file : "$HIP/cache/armour.`trunc($FF)`.bgeo"

What is wrong?

Thanx!

Are you sure : "$HIP/cache/armour.`trunc($FF)`.bgeo"

evaluates to the exact names of existing files?

Maybe try including the whole string in backticks, not only "trunc($FF)".

Not sure though

If I put this string direct in file parameter of File sop, it works perfect

What if you instead did:

return evals(res);

[stass3d]

string createFileName(string in){
    string filename = chsraw(in);
    string res = strreplace(filename, '.$F.', '.`trunc($FF)`.');
    return evals(res);
}

/ -> echo `createFileName("/obj/geo1/s3d_FileBlender1/File_path")`
Expression error: Syntax error
/ ->

string createFileName(string in){
    string filename = chsraw(in);
    string res = strreplace(filename, '.$F.', '.`trunc($FF)`.');
    return evals($res);
}

/ -> echo `createFileName("/obj/geo1/s3d_FileBlender1/File_path")`
Expression error: Undefined variable
/ ->

Shouldn't it be evals(res) without the $ sign?

[stass3d]

I tried both , with $ sign and without:

string createFileName(string in){

string filename = chsraw(in);

string res = strreplace(filename, '.$F.', '.`trunc($FF)`.');

return evals(res);

}

/ -> echo `createFileName("/obj/geo1/s3d_FileBlender1/File_path")`

Expression error: Syntax error

/ ->

Oh right, that's because the name of the file path is not valid.

string createFileName(string in){
string filename = chsraw(in);
string res = strreplace(filename, '.$F.', "." + trunc($FF) + ".");
return evals(res);
}
