NAME

json2yaml.pl : convert JSON to YAML with formatting options.

VERSION

Version 0.13

SYNOPSIS

    json2yaml.pl -i "input.json" -o "output.yaml" --(no-)escape-unicode

    json2yaml.pl -e < "input.json" > "output.yaml"

    # press CTRL-D when done typing JSON to STDIN
    # input must be less than 4K long!
    json2yaml.pl

    # Read input from clipboard or write output to clipboard
    # Only in: Unix / Linux / OSX                
    # (must have already installed xclip or xsel or pbpaste (on OSX))
    json2json.pl -e < $(xclip -o)
    json2json.pl -e < $(pbaste)
    # write the output to the clipboard for further pasting
    json2json.pl -i input.json | xclip -i
    # clicking mouse's middle-button will paste the result

USAGE

json2yaml.pl

Options:

  • --i filename : specify a filename which contains a JSON data structure.

  • --I "string" : specify a string which contains a JSON data structure.

  • --o outputfilename : specify the output filename to write the result to, which will be YAML.

  • --escape-unicode : it will escape all unicode characters, and convert them to something like "\u0386". This is the default option.

  • --no-escape-unicode : it will NOT escape unicode characters. Output will not contain "\u0386" or "\x{386}" but "α" (that's a greek alpha).

Input can be read from an input file (--i), from a string at the command line (--I) (properly quoted!), from STDIN (which also includes a file redirection json2yaml.pl < inputfile.json > outputfile.yaml

For more information see Data::Roundtrip.

CAVEATS

Under Unix/Linux, the maximum number of characters that can be read on a terminal is 4096. So, in reading-from-STDIN mode beware how much you type or how much you copy-paste onto the script. If it complains about malformed input then this is the case. The workaround is to type/paste onto a file and operate on that using --i afile or redirection < afile.
