- Now Terser takes into account side effects inside class `extends` clauses.
- Added parens whenever there's a comment between a return statement and the returned value, to prevent issues with ASI.
- Stopped using raw RegExp objects, since the spec is going to continue to evolve. This ensures Terser is able to process new, unknown RegExp flags and features. This is a breaking change in the AST node AST_RegExp.
## v4.3.2
- Typescript typing fix
- Ensure that functions can't be inlined, by reduce_vars, into places where they're accessing variables with the same name, but from somewhere else.
## v4.3.1
- Fixed an issue from 4.3.0 where any block scope within a for loop erroneously had its parent set to the function scopee
- Fixed an issue where compressing IIFEs with argument expansions would result in some parameters becoming undefined
- addEventListener options argument's properties are now part of the DOM properties list.
## v4.3.0
- Do not drop computed object keys with side effects
- Functions passed to other functions in calls are now wrapped in parentheses by default, which speeds up loading most modules
- Objects with computed properties are now less likely to be hoisted
- Speed and memory efficiency optimizations
- Fixed scoping issues with `try` and `switch`
## v4.2.1
- Minor refactors
- Fixed a bug similar to #369 in collapse_vars
- Functions can no longer be inlined into a place where they're going to be compared with themselves.
- reduce_funcs option is now legacy, as using reduce_vars without reduce_funcs caused some weird corner cases. As a result, it is now implied in reduce_vars and can't be turned off without turning off reduce_vars.
- Bug which would cause a random stack overflow has now been fixed.
## v4.2.0
- When the source map URL is `inline`, don't write it to a file.
- Fixed output parens when a lambda literal is the tag on a tagged template string.
- The `mangle.properties.undeclared` option was added. This enables the property mangler to mangle properties of variables which can be found in the name cache, but whose properties are not known to this Terser run.
- The v8 bug where the toString and source representations of regexes like `RegExp("\\\n")` includes an actual newline is now fixed.
- Now we're guaranteed to not have duplicate comments in the output
- Domprops updates
## v4.1.4
- Fixed a crash when inlining a function into somewhere else when it has interdependent, non-removable variables.
## v4.1.3
- Several issues with the `reduce_vars` option were fixed.
- Starting this version, we only have a dist/bundle.min.js
## v4.1.2
- The hotfix was hotfixed
## v4.1.1
- Fixed a bug where toplevel scopes were being mixed up with lambda scopes
## v4.1.0
- Internal functions were replaced by `Object.assign`, `Array.prototype.some`, `Array.prototype.find` and `Array.prototype.every`.
- A serious issue where some ESM-native code was broken was fixed.
- Performance improvements were made.
- Support for BigInt was added.
- Inline efficiency was improved. Functions are now being inlined more proactively instead of being inlined only after another Compressor pass.
## v4.0.2
(Hotfix release. Reverts unmapped segments PR [#342](https://github.com/terser/terser/pull/342), which will be put back on Terser when the upstream issue is resolved)
## v4.0.1
- Collisions between the arguments of inlined functions and names in the outer scope are now being avoided while inlining
- Unmapped segments are now preserved when compressing a file which has source maps
- Default values of functions are now correctly converted from Mozilla AST to Terser AST
- JSON ⊂ ECMAScript spec (if you don't know what this is you don't need to)
- Export AST_* classes to library users
- Fixed issue with `collapse_vars` when functions are created with the same name as a variable which already exists
- Added `MutationObserverInit` (Object with options for initialising a mutation observer) properties to the DOM property list
- Custom `Error` subclasses are now internally used instead of old-school Error inheritance hacks.
- Documentation fixes
- Performance optimizations
## v4.0.0
- **breaking change**: The `variables` property of all scopes has become a standard JavaScript `Map` as opposed to the old bespoke `Dictionary` object.
- Typescript definitions were fixed
- `terser --help` was fixed
- The public interface was cleaned up
- Fixed optimisation of `Array` and `new Array`
- Added the `keep_quoted=strict` mode to mangle_props, which behaves more like Google Closure Compiler by mangling all unquoted property names, instead of reserving quoted property names automatically.
- Fixed parent functions' parameters being shadowed in some cases
- Allowed Terser to run in a situation where there are custom functions attached to Object.prototype
- And more bug fixes, optimisations and internal changes
## v3.17.0
- More DOM properties added to --mangle-properties's DOM property list
- Closed issue where if 2 functions had the same argument name, Terser would not inline them together properly
- Fixed issue with `hasOwnProperty.call`
- You can now list files to minify in a Terser config file
- Started replacing `new Array(<number>)` with an array literal
- Started using ES6 capabilities like `Set` and the `includes` method for strings and arrays
## v3.16.1
- Fixed issue where Terser being imported with `import` would cause it not to work due to the `__esModule` property. (PR #254 was submitted, which was nice, but since it wasn't a pure commonJS approach I decided to go with my own solution)
## v3.16.0
- No longer leaves names like Array or Object or window as a SimpleStatement (statement which is just a single expression).
- Add support for sections sourcemaps (IndexedSourceMapConsumer)
- Drops node.js v4 and starts using commonJS
- Is now built with rollup
## v3.15.0
- Inlined spread syntax (`[...[1, 2, 3], 4, 5] => [1, 2, 3, 4, 5]`) in arrays and objects.
- Fixed typo in compressor warning
- Fixed inline source map input bug
- Fixed parsing of template literals with unnecessary escapes (Like `\\a`)

The complete solution for [node.js](http://nodejs.org) command-line interfaces, inspired by Ruby's [commander](https://github.com/commander-rb/commander).
[API documentation](http://tj.github.com/commander.js/)
## Installation
$ npm install commander
## Option parsing
Options with commander are defined with the `.option()` method, also serving as documentation for the options. The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options.
```js
#!/usr/bin/env node
/**
* Module dependencies.
*/
var program = require('commander');
program
.version('0.1.0')
.option('-p, --peppers', 'Add peppers')
.option('-P, --pineapple', 'Add pineapple')
.option('-b, --bbq-sauce', 'Add bbq sauce')
.option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')
.parse(process.argv);
console.log('you ordered a pizza with:');
if (program.peppers) console.log(' - peppers');
if (program.pineapple) console.log(' - pineapple');
if (program.bbqSauce) console.log(' - bbq');
console.log(' - %s cheese', program.cheese);
```
Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc.
Note that multi-word options starting with `--no` prefix negate the boolean value of the following word. For example, `--no-sauce` sets the value of `program.sauce` to false.
```js
#!/usr/bin/env node
/**
* Module dependencies.
*/
var program = require('commander');
program
.option('--no-sauce', 'Remove sauce')
.parse(process.argv);
console.log('you ordered a pizza');
if (program.sauce) console.log(' with sauce');
else console.log(' without sauce');
```
To get string arguments from options you will need to use angle brackets <> for required inputs or square brackets [] for optional inputs.
e.g. ```.option('-m --myarg [myVar]', 'my super cool description')```
Then to access the input if it was passed in.
e.g. ```var myInput = program.myarg```
**NOTE**: If you pass a argument without using brackets the example above will return true and not the value passed in.
## Version option
Calling the `version` implicitly adds the `-V` and `--version` options to the command.
When either of these options is present, the command prints the version number and exits.
$ ./examples/pizza -V
0.0.1
If you want your program to respond to the `-v` option instead of the `-V` option, simply pass custom flags to the `version` method using the same syntax as the `option` method.
```js
program
.version('0.0.1', '-v, --version')
```
The version flags can be named anything, but the long option is required.
## Command-specific options
You can attach options to a command.
```js
#!/usr/bin/env node
var program = require('commander');
program
.command('rm <dir>')
.option('-r, --recursive', 'Remove recursively')
.action(function (dir, cmd) {
console.log('remove ' + dir + (cmd.recursive ? ' recursively' : ''))
})
program.parse(process.argv)
```
A command's options are validated when the command is used. Any unknown options will be reported as an error. However, if an action-based command does not define an action, then the options are not validated.
## Coercion
```js
function range(val) {
return val.split('..').map(Number);
}
function list(val) {
return val.split(',');
}
function collect(val, memo) {
memo.push(val);
return memo;
}
function increaseVerbosity(v, total) {
return total + 1;
}
program
.version('0.1.0')
.usage('[options] <file ...>')
.option('-i, --integer <n>', 'An integer argument', parseInt)
.option('-f, --float <n>', 'A float argument', parseFloat)
.option('-r, --range <a>..<b>', 'A range', range)
.option('-l, --list <items>', 'A list', list)
.option('-o, --optional [value]', 'An optional value')
.option('-c, --collect [value]', 'A repeatable value', collect, [])
.option('-v, --verbose', 'A value that can be increased', increaseVerbosity, 0)
.parse(process.argv);
console.log(' int: %j', program.integer);
console.log(' float: %j', program.float);
console.log(' optional: %j', program.optional);
program.range = program.range || [];
console.log(' range: %j..%j', program.range[0], program.range[1]);
console.log(' list: %j', program.list);
console.log(' collect: %j', program.collect);
console.log(' verbosity: %j', program.verbose);
console.log(' args: %j', program.args);
```
## Regular Expression
```js
program
.version('0.1.0')
.option('-s --size <size>', 'Pizza size', /^(large|medium|small)$/i, 'medium')
.option('-d --drink [drink]', 'Drink', /^(coke|pepsi|izze)$/i)
.parse(process.argv);
console.log(' size: %j', program.size);
console.log(' drink: %j', program.drink);
```
## Variadic arguments
The last argument of a command can be variadic, and only the last argument. To make an argument variadic you have to
append `...` to the argument name. Here is an example:
```js
#!/usr/bin/env node
/**
* Module dependencies.
*/
var program = require('commander');
program
.version('0.1.0')
.command('rmdir <dir> [otherDirs...]')
.action(function (dir, otherDirs) {
console.log('rmdir %s', dir);
if (otherDirs) {
otherDirs.forEach(function (oDir) {
console.log('rmdir %s', oDir);
});
}
});
program.parse(process.argv);
```
An `Array` is used for the value of a variadic argument. This applies to `program.args` as well as the argument passed
to your action as demonstrated above.
## Specify the argument syntax
```js
#!/usr/bin/env node
var program = require('commander');
program
.version('0.1.0')
.arguments('<cmd> [env]')
.action(function (cmd, env) {
cmdValue = cmd;
envValue = env;
});
program.parse(process.argv);
if (typeof cmdValue === 'undefined') {
console.error('no command given!');
process.exit(1);
}
console.log('command:', cmdValue);
console.log('environment:', envValue || "no environment given");
```
Angled brackets (e.g. `<cmd>`) indicate required input. Square brackets (e.g. `[env]`) indicate optional input.
## Git-style sub-commands
```js
// file: ./examples/pm
var program = require('commander');
program
.version('0.1.0')
.command('install [name]', 'install one or more packages')
.command('search [query]', 'search with optional query')
.command('list', 'list packages installed', {isDefault: true})
.parse(process.argv);
```
When `.command()` is invoked with a description argument, no `.action(callback)` should be called to handle sub-commands, otherwise there will be an error. This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools.
The commander will try to search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-command`, like `pm-install`, `pm-search`.
Options can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the subcommand from the generated help output. Specifying `true` for `opts.isDefault` will run the subcommand if no other subcommand is specified.
If the program is designed to be installed globally, make sure the executables have proper modes, like `755`.
### `--harmony`
You can enable `--harmony` option in two ways:
* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. Note some os version don’t support this pattern.
* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process.
## Automated --help
The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:
```
$ ./examples/pizza --help
Usage: pizza [options]
An application for pizzas ordering
Options:
-h, --help output usage information
-V, --version output the version number
-p, --peppers Add peppers
-P, --pineapple Add pineapple
-b, --bbq Add bbq sauce
-c, --cheese <type> Add the specified type of cheese [marble]
-C, --no-cheese You do not want any cheese
```
## Custom help
You can display arbitrary `-h, --help` information
by listening for "--help". Commander will automatically
exit once you are done so that the remainder of your program
does not execute causing undesired behaviors, for example
in the following executable "stuff" will not output when
`--help` is used.
```js
#!/usr/bin/env node
/**
* Module dependencies.
*/
var program = require('commander');
program
.version('0.1.0')
.option('-f, --foo', 'enable some foo')
.option('-b, --bar', 'enable some bar')
.option('-B, --baz', 'enable some baz');
// must be before .parse() since
// node's emit() is immediate
program.on('--help', function(){
console.log('')
console.log('Examples:');
console.log(' $ custom-help --help');
console.log(' $ custom-help -h');
});
program.parse(process.argv);
console.log('stuff');
```
Yields the following help output when `node script-name.js -h` or `node script-name.js --help` are run:
```
Usage: custom-help [options]
Options:
-h, --help output usage information
-V, --version output the version number
-f, --foo enable some foo
-b, --bar enable some bar
-B, --baz enable some baz
Examples:
$ custom-help --help
$ custom-help -h
```
## .outputHelp(cb)
Output help information without exiting.
Optional callback cb allows post-processing of help text before it is displayed.
If you want to display help by default (e.g. if no command was provided), you can use something like:
```js
var program = require('commander');
var colors = require('colors');
program
.version('0.1.0')
.command('getstream [url]', 'get stream URL')
.parse(process.argv);
if (!process.argv.slice(2).length) {
program.outputHelp(make_red);
}
function make_red(txt) {
return colors.red(txt); //display the help text in red on the console
}
```
## .help(cb)
Output help information and exit immediately.
Optional callback cb allows post-processing of help text before it is displayed.
## Custom event listeners
You can execute custom actions by listening to command and option events.
```js
program.on('option:verbose', function () {
process.env.VERBOSE = this.verbose;
});
// error on unknown commands
program.on('command:*', function () {
console.error('Invalid command: %s\nSee --help for a list of available commands.', program.args.join(' '));
process.exit(1);
});
```
## Examples
```js
var program = require('commander');
program
.version('0.1.0')
.option('-C, --chdir <path>', 'change the working directory')
.option('-c, --config <path>', 'set config path. defaults to ./deploy.conf')
.option('-T, --no-tests', 'ignore test hook');
program
.command('setup [env]')
.description('run setup commands for all envs')
.option("-s, --setup_mode [mode]", "Which setup mode to use")
.action(function(env, options){
var mode = options.setup_mode || "normal";
env = env || 'all';
console.log('setup for %s env(s) with %s mode', env, mode);
});
program
.command('exec <cmd>')
.alias('ex')
.description('execute the given remote cmd')
.option("-e, --exec_mode <mode>", "Which exec mode to use")
.action(function(cmd, options){
console.log('exec "%s" using %s mode', cmd, options.exec_mode);
}).on('--help', function() {
console.log('');
console.log('Examples:');
console.log('');
console.log(' $ deploy exec sequential');
console.log(' $ deploy exec async');
});
program
.command('*')
.action(function(env){
console.log('deploying "%s"', env);
});
program.parse(process.argv);
```
