catto 😺🖥️

The embeddable C runtime library for the atto programming language. It's used by the DigiCron smartwatch and atto.js.

Building

To build the catto library, run:

./build.sh

The library will be built as a single header file in the dist directory, which will also include a header file used to configure catto. The interpreter and example code will also be built.

Running the interpreter

To start the interpreter, run:

runtime/build/catto

To interrupt running programs, press esc. To exit the interpreter, type exit.

You can also run atto files by running this command, where $FILE is the atto file you want to run:

runtime/build/catto $FILE

Compile with DEBUG_MEMORY defined to get debug information about memory usage for every command entered.

Running the example

To run the example code (found at examples/hello.c), run:

examples/build/hello

Compile with TEST_MEMORY defined to run the example in an infinite loop, which can then be used with a process monitor to check for memory leaks.
