JSON String Encoder for scripters
Properly encode arbitrary input into JSON strings.
Use in conjunction with jpt to quickly encode strings into JSON strings that can be written en masse with a JSONPatch document.
% jse
jse (v1.1) - JSON String Encoder (https://github.com/brunerd/jse)
Usage: jse [-u] [-f] [argument]
-f file flag, treat argument as a filepath
-u encode Unicode characters with \u escaping
argument – string or filepath to encode as JSON string
Input can also be via file redirection, piped input, here doc, or here string
#input as a parameter
% jse 'Wow "cool" 😎'
"Wow \"cool\" 😎"
#same with -u to escape unicode above 0x7e
% jse -u 'Wow "cool" 😎'
"Wow \"cool\" \ud83d\ude0e"
#input via pipe
% echo 'Totally "rad" 🤙' | jse
"Totally \"rad\" 🤙"
#input as a here doc
% jse <<EOT
This line
tabbed line 2
EOT
"This line\n\ttabbed line 2"
#input from file
% jse -f /private/etc/shells
"# List of acceptable shells for chpass(1).\n# Ftpd will not allow users to connect who are not using\n# one of these shells.\n\n/bin/bash\n/bin/csh\n/bin/dash\n/bin/ksh\n/bin/sh\n/bin/tcsh\n/bin/zsh\n"
