argparse 2.0.3
- Fixes bug when accidentally passing a positional argument to
ArgumentParser()
when using Python 3.9. Thanks Kurt Hornik for bug report.
argparse 2.0.1
- Improved passing of arguments to Python from R. In particular should fix bug in using
add_help
argument in ArgumentParser
. Thanks George Chlipala for bug report.
- Removes
getopt
as a dependency.
argparse 2.0.0
- 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.
argparse 1.1.1
- Better support for machines only running Python 2.7.
- DESCRIPTION makes explicit that it requires version 1.0.0 of
proto
dependency.
Thanks Christophe Poulet for bug report.
argparse 1.1.0
- Better support for Unicode arguments/options. Thanks Erick Rocha Fonseca for bug report.
- Fix bug when setting
type='integer'
in add_argument
. Thanks Dominik Mueller for bug report and suggested solution.
- The package
proto
has been moved from Depends
to Imports
in DESCRIPTION
. We now use jsonlite
package instead of rjson
to parse JSON
.
- Better error message when accidentally trying to define a positional argument in
ArgumentParser()
Suggestion of Alex Reinhart.
- Other error message output when an parsing error is detected have been tweaked slightly.
argparse 1.0.7
- Now supports showing program’s version with
action='version'
. Suggestion of Dario Beraldi.
- Fix bug when setting
required=FALSE
in add_argument
. Thanks Claire D. McWhite for bug report.
argparse 1.0.4
- You can now pass in a character vector to the
metavar
argument of add_argument
. Thanks Paul Newell for bug report and a patch.
add_argument
now throws a warning recommending using action “store_true” or “store_false” if type set to “logical” and action set to “store”. Suggestion of Martí Duran Ferrer
- You can now explicitly set a
NULL
default in add_argument
.
Previously one could only implicitly set a NULL
default by not setting any default at all. Suggestion of Hyunsoo Kim.
- Fixes parsing bug when using a very large argument list. Thanks Taylor Pospisil for bug report.
- Parse error usage message now prints to standard error. User requested help message quit status is now zero.
Thanks to PlasmaBinturong for report/request.
- If Python script fails with error pass on error message to user. Thanks to Martí Duran Ferrer for report/request.
argparse 1.0.1
- Fix minor bug when running package tests on machines with both old and new versions of Python. Thanks Prof. Brian Ripley for bug report.
argparse 1.0.0
- Some support for
choices
argument in parser$add_argument
. Thanks Christopher Small for report/request.
- Some support for
formatter_class
argument in ArgumentParser
. Thanks Costas Bouyioukos for report/request.
- Package now looks for Python binaries with
findpython::find_python_cmd
which is a little bit more robust than the previous argparse::find_python_cmd
.
- If
interactive() == TRUE
then parse_args
will no longer quit(status=1)
after printing a help message but will instead throw an error. argparse
will continue to quit(status=1)
after printing a help message for non-interactive Rscripts.
argparse 0.5.3
- Fix bug in
parser$add_argument
for case when we specify a default vector instead of scalar. Thanks Martin Diehl for bug report.
find_python_cmd
will now also look for a python2.7
binary.
