The 'flow' book

Passing Command Line Arguments

Arguments are passed to the flow being executed by flowc by placing them after the flow name in the execution string (either using cargo run -p flowc or flowc directly). e.g. cargo run -p flowc -- flowr/examples/mandlebrot mandel.png 4000x3000 -1.20,0.35 -1,0.20

The context functions include a function called args/get that can be used to read the arguments, allowing them to then be processed in the flow like any other inputs.

Include the args/get function in your flow:

[[process]]
source = "lib://flkowr/args/get"

Then create a connection from the desired output (second arg in this example) of args/get to another function:

[[connection]]
from = "function/get/2"
to = "function/parse_bounds/input"
