# babel-generator
> Turns an AST into code.
## Install
```sh
npm install --save-dev babel-generator
```
## Usage
```js
import {parse} from 'babylon';
import generate from 'babel-generator';
const code = 'class Example {}';
const ast = parse(code);
const output = generate(ast, { /* options */ }, code);
```
## Options
Options for formatting output:
name | type | default | description
-----------------------|----------|-----------------|--------------------------------------------------------------------------
auxiliaryCommentBefore | string | | Optional string to add as a block comment at the start of the output file
auxiliaryCommentAfter | string | | Optional string to add as a block comment at the end of the output file
shouldPrintComment | function | `opts.comments` | Function that takes a comment (as a string) and returns `true` if the comment should be included in the output. By default, comments are included if `opts.comments` is `true` or if `opts.minifed` is `false` and the comment contains `@preserve` or `@license`
retainLines | boolean | `false` | Attempt to use the same line numbers in the output code as in the source code (helps preserve stack traces)
retainFunctionParens | boolean | `false` | Retain parens around function expressions (could be used to change engine parsing behavior)
comments | boolean | `true` | Should comments be included in output
compact | boolean or `'auto'` | `opts.minified` | Set to `true` to avoid adding whitespace for formatting
minified | boolean | `false` | Should the output be minified
concise | boolean | `false` | Set to `true` to reduce whitespace (but not as much as `opts.compact`)
quotes | `'single'` or `'double'` | autodetect based on `ast.tokens` | The type of quote to use in the output
filename | string | | Used in warning messages
flowCommaSeparator | boolean | `false` | Set to `true` to use commas instead of semicolons as Flow property separators
jsonCompatibleStrings | boolean | `false` | Set to true to run `jsesc` with "json": true to print "\u00A9" vs. "©";
Options for source maps:
name | type | default | description
-----------------------|----------|-----------------|--------------------------------------------------------------------------
sourceMaps | boolean | `false` | Enable generating source maps
sourceMapTarget | string | | The filename of the generated code that the source map will be associated with
sourceRoot | string | | A root for all relative URLs in the source map
sourceFileName | string | | The filename for the source code (i.e. the code in the `code` argument). This will only be used if `code` is a string.
## AST from Multiple Sources
In most cases, Babel does a 1:1 transformation of input-file to output-file. However,
you may be dealing with AST constructed from multiple sources - JS files, templates, etc.
If this is the case, and you want the sourcemaps to reflect the correct sources, you'll need
to pass an object to `generate` as the `code` parameter. Keys
should be the source filenames, and values should be the source content.
Here's an example of what that might look like:
```js
import {parse} from 'babylon';
import generate from 'babel-generator';
const a = 'var a = 1;';
const b = 'var b = 2;';
const astA = parse(a, { sourceFilename: 'a.js' });
const astB = parse(b, { sourceFilename: 'b.js' });
const ast = {
type: 'Program',
body: [].concat(astA.program.body, astB.program.body)
};
const { code, map } = generate(ast, { sourceMaps: true }, {
'a.js': a,
'b.js': b
});
// Sourcemap will point to both a.js and b.js where appropriate.
```

.Sh NAME
.Nm jsesc
.Nd escape strings for use in JavaScript string literals
.Sh SYNOPSIS
.Nm
.Op Fl s | -single-quotes Ar string
.br
.Op Fl d | -double-quotes Ar string
.br
.Op Fl w | -wrap Ar string
.br
.Op Fl e | -escape-everything Ar string
.br
.Op Fl 6 | -es6 Ar string
.br
.Op Fl l | -lowercase-hex Ar string
.br
.Op Fl j | -json Ar string

.br
.Op Fl v | -version
.br
.Op Fl h | -help
.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.
.El
.Sh EXIT STATUS
The
.Nm jsesc
utility exits with one of the following values:
.Pp
.Bl -tag -width flag -compact
.It Li 0
.Nm
successfully escaped the given string and printed the result.
.It Li 1
.Nm
wasn't instructed to escape anything (for example, the
.Ar --help
flag was set); or, an error occurred.
.El
.Sh EXAMPLES
.Bl -ohang -offset
.It Sy "jsesc 'foo bar baz'"
Print an escaped version of the given string.
.It Sy echo\ 'foo bar baz'\ |\ jsesc
Print an escaped version of the string that gets piped in.
.El
.Sh BUGS
jsesc's bug tracker is located at <https://github.com/mathiasbynens/jsesc/issues>.
