.Sh DESCRIPTION
|
|
.Nm
|
|
escapes strings for use in JavaScript string literals while generating the shortest possible valid ASCII-only output.
|
|
.Sh OPTIONS
|
|
.Bl -ohang -offset
|
|
.It Sy "-s, --single-quotes"
|
|
Escape any occurrences of ' in the input string as \\', so that the output can be used in a JavaScript string literal wrapped in single quotes.
|
|
.It Sy "-d, --double-quotes"
|
|
Escape any occurrences of " in the input string as \\", so that the output can be used in a JavaScript string literal wrapped in double quotes.
|
|
.It Sy "-w, --wrap"
|
|
Make sure the output is a valid JavaScript string literal wrapped in quotes. The type of quotes can be specified using the
|
|
.Ar -s | --single-quotes
|
|
or
|
|
.Ar -d | --double-quotes
|
|
settings.
|
|
.It Sy "-6, --es6"
|
|
Escape any astral Unicode symbols using ECMAScript 6 Unicode code point escape sequences.
|
|
.It Sy "-e, --escape-everything"
|
|
Escape all the symbols in the output, even printable ASCII symbols.
|
|
.It Sy "-j, --json"
|
|
Make sure the output is valid JSON. Hexadecimal character escape sequences and the \\v or \\0 escape sequences will not be used. Setting this flag enables the
|
|
.Ar -d | --double-quotes
|
|
and
|
|
.Ar -w | --wrap
|
|
settings.
|
|
.It Sy "-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.
|
|
.It Sy "-p, --pretty"
|
|
Pretty-print the output for objects, using whitespace to make it more readable. Setting this flag enables the
|
|
.It Sy "-l, --lowercase-hex"
|
|
Use lowercase for alphabetical hexadecimal digits in escape sequences.
|
|
.Ar -o | --object
|
|
setting.
|
|
.It Sy "-v, --version"
|
|
Print jsesc's version.
|
|
.It Sy "-h, --help"
|
|
Show the help screen.
