rust-automate

This is a simple automate written in Rust that takes a grammar file and an input file and outputs the result if the input is accepted by the grammar.

Usage

In order to use this automate, you need to have Rust installed on your machine. You can install it from here.

git clone https://github.com/iverly/rust-automate
cd rust-automate
cargo run --release -- -g <grammar_file> -i <input_file>

To build the project, you can use the following command:

cargo build --release

The binary will be located in the target/release folder.

The --release flag is optional, but it is recommended to use it for better performance.

Grammar file

You can find some examples of a grammar file in the examples folder.

The grammar file must be a json file and follow the format located in the src/grammar.rs file.

Input file

The input file must be a text file containing the input for the automate.

Examples

To run the examples, you can use the following command:

cargo run -- -g example/complex-correct/grammar.json -i example/complex-correct/input

Replace complex-correct with the example you want to run.

You can also use the --release flag for better performance.

This will run the automate with the complex-correct example. The output should be:

📚 Grammar to use:

S -> C
C -> contact identifier identifier number number | contact identifier identifier number number D | contact identifier identifier number number R | None
R -> rate number number number R | rate number number number D | rate number number number C
D -> delay number number number R | delay number number number D | delay number number number C

📝 Input to be analyzed:

contact A B 20 32
rate 1 10 3
rate 5 1 26
delay 3 50 300

contact T A 10 3
delay 1 5 20

contact Y U 5 16

✅ The input is correct
