Hi,
I am looking for help with a script or to help guide me to a script that will allow me to read contents from a saved file and compare to a string value.
I already have a script that will get the value of a servo, and store it to a file. I would like to read that same file and compare the values.
Thanks.
After you have created and saved data to your file you can use these commands to retrieve data from the file after you open or re-open it
So something like this?
So, lets say you stored a value in a test file, to read it you can use
@RichardR , Thank You, is there a way to read each line in the file and then compare? Variable Watcher has a bunch of numbers all into one string value.
Yes, you can do it like this for simplicity...
So $contents1 through $contents4 variables store the data of the first 4 lines of data that was in the file respectively...
I then would need to read the file, see how many lines, then create the $contents string variable according to how many lines I have... am I thinking right on this? Or is there a better way?
Maybe I need to read from the file and then make an array then compare all the array entries to the servo value?
If you're the one writing to the file, u shouldn't need to check how many lines are there because u will already know. You're the creator
I assume you want to write servo positions to be saved and resumed at a later date?
@DJ Silly Me.. Yes, you are correct!
:)
