Currently, the supported operations are:
canonize: canonize the Unicode representation of the IPA stringchars: list all IPA characters appearing in the IPA stringcheck: check if the given Unicode string is IPA validclean: remove characters that are not IPA validu2a: print the corresponding ARPABET (ASCII IPA) stringu2k: print the corresponding Kirshenbaum (ASCII IPA) string
Run with the --help parameter to list all the available options:
$ python -m ipapy --help
usage: __main__.py [-h] [-i] [-p] [--separator [SEPARATOR]] [-s] [-u]
command string
ipapy perform a command on the given IPA/Unicode string
positional arguments:
command [canonize|chars|check|clean|u2a|u2k]
string String to canonize, check, clean, or convert
optional arguments:
-h, --help show this help message and exit
-i, --ignore Ignore Unicode characters that are not IPA valid
-p, --print-invalid Print Unicode characters that are not IPA valid
--separator [SEPARATOR]
Print IPA chars separated by this character (default:
'')
-s, --single-char-parsing
Perform single character parsing instead of maximal
parsing
-u, --unicode Print each Unicode character that is not IPA valid
with its Unicode codepoint and nameExamples:
