NAME Devel::JSON - Easy JSON output for one-liners SYNOPSIS $ perl -d:JSON -e '[ 1..3 ]' [ 1, 2, 3 ] $ perl -d:JSON -e '{b => 2, c => 4}' { "b": 2, "c": 4 } Default output encoding is UTF-x if this is the charset of the locale: $ perl -d:JSON -e "qq<\N{SNOWMAN}>" "☃" Force ASCII output: $ perl -d:JSON=ascii -e "qq<\N{SNOWMAN}>" "\u2603" Booleans: $ perl -d:JSON -MJSON::PP -e 'JSON::PP::true' true DESCRIPTION If you use this module from the command-line, the last value of your one-liner (-e) code will be serialized as JSON data. The expression is evaluated in scalar context. The output will be either UTF-x (UTF-8, UTF-16...) or just ASCII, depending on your locale (check LC_CTYPE on Unix or GNU). As a convenience (because you may want to deal with non-ASCII content in your -e source), your code is converted from bytes using the current locale. The following JSON options are enabled by default: pretty canonical allow_nonref You can enable more options by giving import arguments (a '-' prefix disables the option): # Force ASCII output $ perl -d:JSON=ascii -e '[1..3]' # Disable pretty (note '-' before the name) $ perl -d:JSON=-pretty -e '[1..3]' # Non-ASCII in -e $ perl -d:JSON=ascii -e '"Mengué"' "Mengu\u00e9" SEE ALSO JSON, JSON::MaybeXS, json-to (App::JSON::to).
