This release updates our examples to include demonstration of new features.

New features in this release include:

• The pragma built-in command.
  • This allows getting/setting interpreter flags.
  • Currently the only supported pragma is pragma("strict");, but this might change in the future.
• Support for string matching against regular expressions, via the match() function.
  • This supports captures as well as truthiness testing.
• The registration of all known environmental-variables at startup-time.
  • Each variable is prefixed with a $ symbol, which should be familiar to shell-users.

This release updates the parser to add some new features:

• <= and >= may be used as comparison/boolean functions.
• ** is a POW operator (2 ** 3 => 8).
• ` is a backtick operator allowing command execution.

The backtick operator returns NULL on failure, otherwise a hash with two keys:

• stdout
  • The output hte command produced on STDOUT.
• stderr
  • The output the command produced on STDERR.

The backtick operator is demonstrated in examples/exec.mon

We've also added support for writing to files, and STDOUT/STDERR via the new standard-library function write.

• Example of writing to a file examples/file-writing.mon
• Example of writing explicitly to STDOUT or STDERR examples/stdout-stderr.mon

The standard-library was also updated to include support for reading directory-contents via the function directory.glob, as demonstrated in examples/glob.mon

Finally it is now possible to return an array of hash-keys via the new standard library function keys - which is demonstrated in examples/hash.mon

This is a bug-fix release primarily affecting multibyte characters.

• Bugfix: The string-length calculation is now correct for multibyte characters.
  • len("狐犬") -> 2
• Bugfix: Indexing operations on strings are now correct for multibyte characters:
  • "狐犬"[0] -> "狐"
  • "狐犬"[1] -> "犬"
• Bugfix: The interpreter correctly loads files from the shebang line.

This is the initial binary release of monkey, future releases will have a useful changelog.
