COMMON_EXPORTED_FUNCTIONS =

It may appear that mode 0 and mode 1 requires the same set of functions since they both load bytecodes, but due to the fact that mode 0 only loads pre-defined bytecode array, chances are optimizers may perform some tricks to eliminate parts of the source code for mode 0. Hence we still distinguish mode 0 from mode 1 here

  • Functions required by loading modes

  • Functions that are customly added by users

Attributes

  • gem_function_file - File name of functions exported by mrbgems, this is

generated by scripts/gen_gems_config.rb

  • loading_mode - Loading mode

  • custom_functions - Array of custom functions added by user
