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"
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"
