  • YOMIKOMU_STORAGE (default: fs): choose storage type.
    • 'fs' (default) stores binaries in the same directory (for examlple, x.rb will be compiled to x.rb.yarb in the same directory).
    • 'fs2' stores binaries in specific directory.
    • 'fsgz' stores files same as 'fs', but gz compressed.
    • 'fs2gz' stores files same as 'fs2', but gz compressed.
    • 'dbm' stores binaries using dbm.
    • 'flatfile' stores binaries in one flat file. Updating is not supported. Use with YOMIKOMU_AUTO_COMPILE.
  • YOMIKOMU_STORAGE_DIR (default: "~/.ruby_binaries"): choose directory where binary files are stored.
  • YOMIKOMU_AUTO_COMPILE (default: false): if this value is true, then compile all required scripts implicitly.

  • YOMIKOMU_DEBUG (default: not defined): show more information.
