| 29 | .Sh DESCRIPTION
|
|---|
| 30 | .Nm
|
|---|
| 31 | escapes strings for use in JavaScript string literals while generating the shortest possible valid ASCII-only output.
|
|---|
| 32 | .Sh OPTIONS
|
|---|
| 33 | .Bl -ohang -offset
|
|---|
| 34 | .It Sy "-s, --single-quotes"
|
|---|
| 35 | 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.
|
|---|
| 36 | .It Sy "-d, --double-quotes"
|
|---|
| 37 | 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.
|
|---|
| 38 | .It Sy "-w, --wrap"
|
|---|
| 39 | Make sure the output is a valid JavaScript string literal wrapped in quotes. The type of quotes can be specified using the
|
|---|
| 40 | .Ar -s | --single-quotes
|
|---|
| 41 | or
|
|---|
| 42 | .Ar -d | --double-quotes
|
|---|
| 43 | settings.
|
|---|
| 44 | .It Sy "-6, --es6"
|
|---|
| 45 | Escape any astral Unicode symbols using ECMAScript 6 Unicode code point escape sequences.
|
|---|
| 46 | .It Sy "-e, --escape-everything"
|
|---|
| 47 | Escape all the symbols in the output, even printable ASCII symbols.
|
|---|
| 48 | .It Sy "-j, --json"
|
|---|
| 49 | 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
|
|---|
| 50 | .Ar -d | --double-quotes
|
|---|
| 51 | and
|
|---|
| 52 | .Ar -w | --wrap
|
|---|
| 53 | settings.
|
|---|
| 54 | .It Sy "-o, --object"
|
|---|
| 55 | 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.
|
|---|
| 56 | .It Sy "-p, --pretty"
|
|---|
| 57 | Pretty-print the output for objects, using whitespace to make it more readable. Setting this flag enables the
|
|---|
| 58 | .It Sy "-l, --lowercase-hex"
|
|---|
| 59 | Use lowercase for alphabetical hexadecimal digits in escape sequences.
|
|---|
| 60 | .Ar -o | --object
|
|---|
| 61 | setting.
|
|---|
| 62 | .It Sy "-v, --version"
|
|---|
| 63 | Print jsesc's version.
|
|---|
| 64 | .It Sy "-h, --help"
|
|---|
| 65 | Show the help screen.
