r-argparse - argparse v2.2.3

• Character values are now passed as "raw" strings to Python (#51).

  • In particular this avoids triggering an error in Python 3.12 when creating a string with escapes not supported by Python e.g. default = "\\D" will continue to return a default value of "\\D" instead of triggering an error.
  • However, this also means that any Python accepted escape sequences will no longer be interpreted as an escape sequence. If relying on such behaviour you may need to instead use the appropriate R escape sequences or Unicode values instead of Python escape sequences:
  • E.g. default = "\\t" will now return a default value of "\\t" (a t preceded by an (escaped) backslash) instead of "\t" (a horizontal tab).

r-argparse - argparse v2.2.1

• We now support the following ArgumentParser() methods:

  • format_help()
  • format_usage()
  • parse_intermixed_args() (#45)
  • parse_known_intermixed_args() (#45)
  • set_defaults() (#43). Suggestion of @oliverbothe.

• When an error is thrown by ArgumentParser()$parse_args() and interactive() is FALSE and getOption("error") is NULL then we now use a quieter default error handler that doesn't output a trailing "Execution halted".

• add_argument() now allows "numeric" as an alias for "double" for the type argument (#42). Suggestion of @dariober.

• ArgumentParser() now handles description arguments with newlines in them (#44). Thanks Arthur Gilly (@agilly) for bug report.

r-argparse - argparse v2.1.6

• The errors raised by ArgumentParser()$parse_args() are now of class "argparseparseerror".

They are now less verbose when interactive() is FALSE (#40).

There may still be a trailing "Execution halted" line output by R's default error handler (when interactive() is FALSE). This can be silenced by setting a new error handler near the top of your Rscript e.g.

r if (!interactive()) options(error=function(e) quit('no', status = 1, runLast = FALSE))

r-argparse - argparse v2.1.5

• add_argument now uses as.logical() logic to cast variables to logical values if type = "logical" and action = "store" or action = "append" instead of using Python's bool() logic (#39).

  • We throw an error if we would get an NA by coercion.
  • We no longer throw a warning when using type = "logical" and action = "store" suggesting users instead use action = "store_true" or action = "store_false".

• Now uses R6 classes instead of proto classes (#25).
  The typical user shouldn't need to change any argparse code but I did make private the previously public python_code element of the object returned by ArgumentParser().
• Parsers now support add_subparsers (#14). Suggestion of Zebulun Arendsee.
• Parsers now support add_argument_group (#26).
  Suggestion of Dario Beraldi.
• Parsers now support add_mutually_exclusive_group (#23).
  Suggestion of Vince Reuter.
