# Unique number allocator for JavaScript.
Version 1.0.14 [![number-allocator CI](https://github.com/redboltz/number-allocator/workflows/number-allocator%20CI/badge.svg)](https://github.com/redboltz/number-allocator/actions) [![codecov](https://codecov.io/gh/redboltz/number-allocator/branch/main/graph/badge.svg)](https://codecov.io/gh/redboltz/number-allocator)
## How to use
```js
const NumberAllocator = require('number-allocator').NumberAllocator
// Construct a NumerAllocator that has [0-10] numbers.
// All numbers are vacant.
const a = new NumberAllocator(0, 10)
// Allocate the least vacant number.
const num0 = a.alloc()
console.log(num0) // 0
// Allocate the least vacant number.
const num1 = a.alloc()
console.log(num1) // 1
// Use any vacant number.
const ret1 = a.use(5) // 5 is marked as used(occupied) in the NumberAllocator.
console.log(ret1) // true
// If use the used number, then return false.
const ret2 = a.use(1) // 1 has already been used, then return false
console.log(ret2) // false
// Free the used number.
a.free(1)
// Now 1 becomes vacant again.
const ret3 = a.use(1)
console.log(ret3) // true
// Get the lowest vacant number without marking used.
const num2 = a.firstVacant()
console.log(num2) // 2
// Clear all used mark. Now [0-10] are allocatable again.
a.clear()
```
## Reference
### NumberAllocator(min, max)
Constructor
- min: Number
- The maximum number of allocatable. The number must be integer.
- max: Number
- The minimum number of allocatable. The number must be integer.
The all numbers are set to vacant status.
Time Complexity O(1)
### firstVacant()
Get the first vacant number. The status of the number is not updated.
Time Complexity O(1)
- return: Number
- The first vacant number. If all numbers are occupied, return null.
When alloc() is called then the same value will be allocated.
### alloc()
Allocate the first vacant number. The number become occupied status.
Time Complexity O(1)
- return: Number
- The first vacant number. If all numbers are occupied, return null.
### use(num)
Use the number. The number become occupied status.
If the number has already been occupied, then return false.
Time Complexity O(logN) : N is the number of intervals (not numbers)
- num: Number
- The number to request use.
- return: Boolean
- If `num` was not occupied, then return true, otherwise return false.
### free(num)
Deallocate the number. The number become vacant status.
Time Complexity O(logN) : N is the number of intervals (not numbers)
- num: Number
- The number to deallocate. The number must be occupied status.
In other words, the number must be allocated by alloc() or occupied be use().
### clear()
Clear all occupied numbers.
The all numbers are set to vacant status.
Time Complexity O(1)
### intervalCount()
Get the number of intervals. Interval is internal structure of this library.
This function is for debugging.
Time Complexity O(1)
- return: Number
- The number of intervals.
### dump()
Dump the internal structor of the library.
This function is for debugging.
Time Complexity O(N) : N is the number of intervals (not numbers)
## Internal structure
NumberAllocator has a sorted-set of Interval.
Interval has `low` and `high` property.
I use `[low-high]` notation to describe Interval.
When NumberAllocator is constructed, it has only one Interval(min, max).
Let's say `new NumberAllocator(1, 9)` then the internal structure become as follows:
```
[1-------9]
```
When `alloc()` is called, the first Interval.low is returned.
And then the interval is shrinked.
```
alloc()
return 1
[2------9]
```
When `use(5)` is called, the interval is separated to the two intervals.
```
use(5)
[2-4] [6--9]
```
When `alloc()` is called again, the first Interval.low is returned.
And then the interval is shrinked.
```
alloc()
return 2
[3-4] [6--9]
```
When `free(1)` is called. the interval is inseted.
```
free(1)
[1] [3-4] [6--9]
```
When `free(2)` is called. the interval is inseted.
And check the left and right intervals. If they are continuours, then concatinate to them.
```
free(1)
[1][2][3-4] [6--9]
[1-------4] [6--9]
```
When `clear()` is called, then reset the interval as follows:
```
[1-------9]
```
When `intervalCount()` is called, then the number of intervals is retuned.
In the following case, return 3.
```
intervalCount()
return 3
[1] [3-4] [6--9]
```
Interval management (insertion/concatination/shrinking) is using efficient way.
Insert/Delete operation to sorted-set is minimized.
Some of operations requires O(logN) time complexity. N is number of intervals.
If the maximum count of allocatable values is M, N is at most floor((M + 1) / 2),
In this example, M is 9 so N is at most 5 as follows:
```
[1] [3] [5] [7] [9]
```

# debug
[![OpenCollective](https://opencollective.com/debug/backers/badge.svg)](#backers)
[![OpenCollective](https://opencollective.com/debug/sponsors/badge.svg)](#sponsors)
<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
A tiny JavaScript debugging utility modelled after Node.js core's debugging
technique. Works in Node.js and web browsers.
## Installation
```bash
$ npm install debug
```
## Usage
`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
Example [_app.js_](./examples/node/app.js):
```js
var debug = require('debug')('http')
, http = require('http')
, name = 'My App';
// fake app
debug('booting %o', name);
http.createServer(function(req, res){
debug(req.method + ' ' + req.url);
res.end('hello\n');
}).listen(3000, function(){
debug('listening');
});
// fake worker of some kind
require('./worker');
```
Example [_worker.js_](./examples/node/worker.js):
```js
var a = require('debug')('worker:a')
, b = require('debug')('worker:b');
function work() {
a('doing lots of uninteresting work');
setTimeout(work, Math.random() * 1000);
}
work();
function workb() {
b('doing some work');
setTimeout(workb, Math.random() * 2000);
}
workb();
```
The `DEBUG` environment variable is then used to enable these based on space or
comma-delimited names.
Here are some examples:
<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
#### Windows command prompt notes
##### CMD
On Windows the environment variable is set using the `set` command.
```cmd
set DEBUG=*,-not_this
```
Example:
```cmd
set DEBUG=* & node app.js
```
##### PowerShell (VS Code default)
PowerShell uses different syntax to set environment variables.
```cmd
$env:DEBUG = "*,-not_this"
```
Example:
```cmd
$env:DEBUG='app';node app.js
```
Then, run the program to be debugged as usual.
npm script example:
```js
"windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
```
## Namespace Colors
Every debug instance has a color generated for it based on its namespace name.
This helps when visually parsing the debug output to identify which debug instance
a debug line belongs to.
#### Node.js
In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
otherwise debug will only use a small handful of basic colors.
<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
#### Web Browser
Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
option. These are WebKit web inspectors, Firefox ([since version
31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
and the Firebug plugin for Firefox (any version).
<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
## Millisecond diff
When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
## Conventions
If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
## Wildcards
The `*` character may be used as a wildcard. Suppose for example your library has
debuggers named "connect:bodyParser", "connect:compress", "connect:session",
instead of listing all three with
`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
You can also exclude specific debuggers by prefixing them with a "-" character.
For example, `DEBUG=*,-connect:*` would include all debuggers except those
starting with "connect:".
## Environment Variables
When running through Node.js, you can set a few environment variables that will
change the behavior of the debug logging:
| Name | Purpose |
|-----------|-------------------------------------------------|
| `DEBUG` | Enables/disables specific debugging namespaces. |
| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). |
| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
| `DEBUG_DEPTH` | Object inspection depth. |
| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
__Note:__ The environment variables beginning with `DEBUG_` end up being
converted into an Options object that gets used with `%o`/`%O` formatters.
See the Node.js documentation for
[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
for the complete list.
## Formatters
Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
Below are the officially supported formatters:
| Formatter | Representation |
|-----------|----------------|
| `%O` | Pretty-print an Object on multiple lines. |
| `%o` | Pretty-print an Object all on a single line. |
| `%s` | String. |
| `%d` | Number (both integer and float). |
| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
| `%%` | Single percent sign ('%'). This does not consume an argument. |
### Custom formatters
You can add custom formatters by extending the `debug.formatters` object.
For example, if you wanted to add support for rendering a Buffer as hex with
`%h`, you could do something like:
```js
const createDebug = require('debug')
createDebug.formatters.h = (v) => {
return v.toString('hex')
}
// …elsewhere
const debug = createDebug('foo')
debug('this is hex: %h', new Buffer('hello world'))
// foo this is hex: 68656c6c6f20776f726c6421 +0ms
```
## Browser Support
You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
if you don't want to build it yourself.
Debug's enable state is currently persisted by `localStorage`.
Consider the situation shown below where you have `worker:a` and `worker:b`,
and wish to debug both. You can enable this using `localStorage.debug`:
```js
localStorage.debug = 'worker:*'
```
And then refresh the page.
```js
a = debug('worker:a');
b = debug('worker:b');
setInterval(function(){
a('doing some work');
}, 1000);
setInterval(function(){
b('doing some work');
}, 1200);
```
In Chromium-based web browsers (e.g. Brave, Chrome, and Electron), the JavaScript console will—by default—only show messages logged by `debug` if the "Verbose" log level is _enabled_.

## Output streams
By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
Example [_stdout.js_](./examples/node/stdout.js):
```js
var debug = require('debug');
var error = debug('app:error');
// by default stderr is used
error('goes to stderr!');
var log = debug('app:log');
// set this namespace to log via console.log
log.log = console.log.bind(console); // don't forget to bind to console!
log('goes to stdout');
error('still goes to stderr!');
// set all output to go via console.info
// overrides all per-namespace log settings
debug.log = console.info.bind(console);
error('now goes to stdout via console.info');
log('still goes to stdout, but via console.info now');
```
## Extend
You can simply extend debugger
```js
const log = require('debug')('auth');
//creates new debug instance with extended namespace
const logSign = log.extend('sign');
const logLogin = log.extend('login');
log('hello'); // auth hello
logSign('hello'); //auth:sign hello
logLogin('hello'); //auth:login hello
```
## Set dynamically
You can also enable debug dynamically by calling the `enable()` method :
```js
let debug = require('debug');
console.log(1, debug.enabled('test'));
debug.enable('test');
console.log(2, debug.enabled('test'));
debug.disable();
console.log(3, debug.enabled('test'));
```
print :
```
1 false
2 true
3 false
```
Usage :
`enable(namespaces)`
`namespaces` can include modes separated by a colon and wildcards.
Note that calling `enable()` completely overrides previously set DEBUG variable :
```
$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
=> false
```
`disable()`
Will disable all namespaces. The functions returns the namespaces currently
enabled (and skipped). This can be useful if you want to disable debugging
temporarily without knowing what was enabled to begin with.
For example:
```js
let debug = require('debug');
debug.enable('foo:*,-foo:bar');
let namespaces = debug.disable();
debug.enable(namespaces);
```
Note: There is no guarantee that the string will be identical to the initial
enable string, but semantically they will be identical.
## Checking whether a debug target is enabled
After you've created a debug instance, you can determine whether or not it is
enabled by checking the `enabled` property:
```javascript
const debug = require('debug')('http');
if (debug.enabled) {
// do stuff...
}
```
You can also manually toggle this property to force the debug instance to be
enabled or disabled.
## Usage in child processes
Due to the way `debug` detects if the output is a TTY or not, colors are not shown in child processes when `stderr` is piped. A solution is to pass the `DEBUG_COLORS=1` environment variable to the child process.
For example:
```javascript
worker = fork(WORKER_WRAP_PATH, [workerPath], {
stdio: [
/* stdin: */ 0,
/* stdout: */ 'pipe',
/* stderr: */ 'pipe',
'ipc',
],
env: Object.assign({}, process.env, {
DEBUG_COLORS: 1 // without this settings, colors won't be shown
}),
});
worker.stderr.pipe(process.stderr, { end: false });
```

# ms
![CI](https://github.com/vercel/ms/workflows/CI/badge.svg)
Use this package to easily convert various time formats to milliseconds.
## Examples
```js
ms('2 days') // 172800000
ms('1d') // 86400000
ms('10h') // 36000000
ms('2.5 hrs') // 9000000
ms('2h') // 7200000
ms('1m') // 60000
ms('5s') // 5000
ms('1y') // 31557600000
ms('100') // 100
ms('-3 days') // -259200000
ms('-1h') // -3600000
ms('-200') // -200
```
### Convert from Milliseconds
```js
ms(60000) // "1m"
ms(2 * 60000) // "2m"
ms(-3 * 60000) // "-3m"
ms(ms('10 hours')) // "10h"
```
### Time Format Written-Out
```js
ms(60000, { long: true }) // "1 minute"
ms(2 * 60000, { long: true }) // "2 minutes"
ms(-3 * 60000, { long: true }) // "-3 minutes"
ms(ms('10 hours'), { long: true }) // "10 hours"
```
## Features
- Works both in [Node.js](https://nodejs.org) and in the browser
- If a number is supplied to `ms`, a string with a unit is returned
- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
## Related Packages
- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
## Caught a Bug?
1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
2. Link the package to the global module directory: `npm link`
3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
As always, you can run the tests using: `npm test`
