The pratt command is a stripped-down expression parser based on the
Pratt parser. To help understand Pratt parsing, the command also
provides a naive, recursive, right-associative expression parser and a naive,
iterative, left-associative expression parser.
Try it with:
go run ./main.go '1 + 2 * 3'
The svg command is meant to be used with the pratt command. It generates
and opens an SVG image of the expression tree in the default SVG viewer.
Try it with:
go install ./...
pratt '1 * 2 + 3 * 4' | svg -o
You can install by using the following command.
