DESCRIPTION
jsesc escapes strings for use in JavaScript string literals while gener-
ating the shortest possible valid ASCII-only output.
OPTIONS
-s, --single-quotes
Escape any occurrences of ' in the input string as \', so that the out-
put can be used in a JavaScript string literal wrapped in single quotes.
-d, --double-quotes
Escape any occurrences of " in the input string as \", so that the out-
put can be used in a JavaScript string literal wrapped in double quotes.
-w, --wrap
Make sure the output is a valid JavaScript string literal wrapped in
quotes. The type of quotes can be specified using the -s |
--single-quotes or -d | --double-quotes settings.
-6, --es6
Escape any astral Unicode symbols using ECMAScript 6 Unicode code point
escape sequences.
-e, --escape-everything
Escape all the symbols in the output, even printable ASCII symbols.
-j, --json
Make sure the output is valid JSON. Hexadecimal character escape se-
quences and the \v or \0 escape sequences will not be used. Setting this
flag enables the -d | --double-quotes and -w | --wrap settings.
-o, --object
Treat the input as a JavaScript object rather than a string. Accepted
values are flat arrays containing only string values, and flat objects
containing only string values.
-p, --pretty
Pretty-print the output for objects, using whitespace to make it more
readable. Setting this flag enables the
-l, --lowercase-hex
Use lowercase for alphabetical hexadecimal digits in escape sequences.
-o | --object setting.
-v, --version
Print jsesc's version.
-h, --help
Show the help screen.
EXIT STATUS
The jsesc utility exits with one of the following values:
0 jsesc successfully escaped the given string and printed the re-
sult.
1 jsesc wasn't instructed to escape anything (for example, the
--help flag was set); or, an error occurred.
EXAMPLES
jsesc 'foo bar baz'
Print an escaped version of the given string.
echo 'foo bar baz' | jsesc
Print an escaped version of the string that gets piped in.
