mirai 0.6.0.9000 (development)

mirai 0.6.02022-09-16

  • Notice: older package versions will no longer be supported by ‘nanonext’ >= 0.6.0. Please ensure you are using the latest version of ‘mirai’ or else refrain from upgrading ‘nanonext’.
  • Internal enhancements to daemons() and %>>% deferred evaluation pipe.

mirai 0.5.32022-08-16

  • mirai() gains a ‘.args’ argument for passing a list of objects already in the calling environment, allowing for example mirai(func(x, y, z), .args = list(x, y, z)) rather than having to specify mirai(func(x, y, z), x = x, y = y, z = z).
  • Errors from inside a mirai will now return the error message as a character string of class ‘miraiError’ and ‘errorValue’, rather than just a nul byte. Utility function is_mirai_error() should be used in place of is_nul_byte(), which is no longer re-exported.
  • is_error_value() can be used to test for all errors, including timeouts where the ‘.timeout’ argument has been used.
  • All re-exports from ‘nanonext’ have been brought in-package for better documentation.

mirai 0.5.22022-07-21

  • Internal optimisations requiring nanonext >= 0.5.2.

mirai 0.5.02022-06-21

  • Implements the %>>% deferred evaluation pipe.
  • Adds ‘.timeout’ argument to mirai() to ensure a mirai always resolves even if the child process crashes etc.

mirai 0.4.12022-04-21

  • Exits cleanly when daemons have not been explicitly zeroed prior to ending an R session.
  • Fixes possible hang on Windows when shutting down daemons.

mirai 0.4.02022-04-14

  • Back to a pure R implementation thanks to enhanced internal design at nanonext.
  • Adds auxiliary function is_mirai() to test if an object is a mirai.
  • Versioning system to synchronise with nanonext e.g. v0.4.x requires nanonext >= 0.4.0.

mirai 0.2.02022-03-28

  • The value of a mirai is now stored at $data to optimally align with the underlying implementation.
  • Package now contains C code (requires compilation), using weak references for simpler management of resources.
  • Switch to abstract sockets on Linux.

mirai 0.1.12022-03-15

  • mirai() added as an alias for eval_mirai(); supports evaluating arbitrary length expressions wrapped in {}.
  • A mirai now resolves automatically without requiring call_mirai(). Access the $value directly and an ‘unresolved’ logical NA will be returned if the async operation is yet to complete.
  • stop_mirai() added as a function to stop evaluation of an ongoing async operation.
  • Auxiliary functions is_nul_byte() and unresolved() re-exported from {nanonext} to test for evaluation errors and resolution of a ‘mirai’ respectively.
  • New daemons() interface to set and manage persistent background processes for receiving ‘mirai’ requests.

mirai 0.1.02022-02-16

  • Initial release.
