Writing values

With Proctal not only can you read the contents in memory straight from your terminal, you can also easily modify them. The write command is able to write text, integers, IEEE754 floating point numbers, CPU instructions and more.
The command accepts type options. You can find out all about them here.
Here's how you would write a 32-bit integer with the value 0 at the memory address 7FFE79DEA90C in a program whose PID is 12345.

$ proctal write --pid=12345 --address=7FFE79DEA90C --type=integer --integer-bits=32 0

You can pass the --pause option to keep the program paused while writing.

Writing arrays

But what if you had an array of 32-bit integers in memory? One way to write all the elements would be to execute the write command at the corresponding address for each element. But a better way is to take advantage of the --array option. It takes the number of elements as its value.
Here's how you would write an array of 5 32-bit integers.

$ proctal write --pid=12345 --address=7FFE79DEA90C --type=integer --integer-bits=32 --array=5 0 0 0 0 0

You can also let the command loop back to the first value if you don't provide the same number of values as the array option. This means that the previous command is equivalent to this one:

$ proctal write --pid=12345 --address=7FFE79DEA90C --type=integer --integer-bits=32 --array=5 0

Repeat writing

With the --repeat option you can make the command repeatedly write the same values over and over again. With the --repeat-delay option you can even specify the delay in milliseconds between writes.
The command will keep running until you tell it to stop. You can stop it by sending it the SIGINT signal (^C on most terminals).
By default the delay is set to be 5 milliseconds.

Binary input

The --binary option makes the command write values from the standard input stream in binary.
