Methan0l

A dynamically-typed multi-paradigm interpreted programming language.

Language Reference Documentation

Available here.

How to Use the Interpreter CLI

Execute a program:

./methan0l [interpreter-args] /path/to/src-file.mt0 [script-args]

Start the interpreter in interactive mode:

./methan0l [interpreter-args]

Interpreter arguments:

• Pause after program execution (by requesting user input):
  --no-exit

• Launch interactive session in CAS mode (save and print out evalution result for each expression):
  --cas

• Set max allocatable heap capacity (in bytes):
  --max-mem=123

• Set initial heap capacity (in bytes):
  --initial-mem=123

• Allocate the whole heap fully (capacity is determined by the --max-mem value) on interpreter launch:
  --allocate-fully

• Disable the heap limit. Stops the interpreter from throwing an exception on allocating more than max heap capacity:
  --no-heap-limit

• Disable monotonic buffer upstream for heap allocations (for testing purposes, may get removed):
  --no-flat-buffer

• Print version string:
  --version

Building Methan0l

Build requirements:
* GNU make 4.2+ * g++ 10+ * libboost

For Windows machines you need to have ports of everything listed above installed and added to PATH (MSYS2 ports are recommended).

Build interpreter & CLI:

cd build && make all

Build interpreter only (libmethan0l.so):

cd build && make lib

As a result, libmethan0l.so and / or CLI binary will be located in build directory and all headers will be copied under build/include/ preserving their directory structure.

Build modules:

cd build && make modules

or to build a specific module:

cd modules/[module_name] && make

where [module_name] is the name of the directory that contains the module’s sources.

Create an archive with CLI binary, libmethan0l.so, all modules and development headers:

cd build && make release

Resulting methan0l-<OS_NAME><BITS>.tar.gz will be located in build directory.
