# upath v1.2.0
|
||
|
|
||
|
[![Build Status](https://travis-ci.org/anodynos/upath.svg?branch=master)](https://travis-ci.org/anodynos/upath)
|
||
|
[![Up to date Status](https://david-dm.org/anodynos/upath.png)](https://david-dm.org/anodynos/upath)
|
||
|
|
||
|
A drop-in replacement / proxy to nodejs's `path` that:
|
||
|
|
||
|
* Replaces the windows `\` with the unix `/` in all string params & results. This has significant positives - see below.
|
||
|
|
||
|
* Adds **filename extensions** functions `addExt`, `trimExt`, `removeExt`, `changeExt`, and `defaultExt`.
|
||
|
|
||
|
* Add a `normalizeSafe` function to preserve any meaningful leading `./` & a `normalizeTrim` which additionally trims any useless ending `/`.
|
||
|
|
||
|
* Plus a helper `toUnix` that simply converts `\` to `/` and consolidates duplicates.
|
||
|
|
||
|
**Useful note: these docs are actually auto generated from [specs](https://github.com/anodynos/upath/blob/master/source/spec/upath-spec.coffee), running on Linux.**
|
||
|
|
||
|
Notes:
|
||
|
|
||
|
* `upath.sep` is set to `'/'` for seamless replacement (as of 1.0.3).
|
||
|
|
||
|
* upath has no runtime dependencies, except built-in `path` (as of 1.0.4)
|
||
|
|
||
|
* travis-ci tested in node versions 4 to 12
|
||
|

||
|
## Why ?
|
||
|
|
||
|
Normal `path` doesn't convert paths to a unified format (ie `/`) before calculating paths (`normalize`, `join`), which can lead to numerous problems.
|
||
|
Also path joining, normalization etc on the two formats is not consistent, depending on where it runs. Running `path` on Windows yields different results than when it runs on Linux / Mac.
|
||
|
|
||
|
In general, if you code your paths logic while developing on Unix/Mac and it runs on Windows, you may run into problems when using `path`.
|
||
|
|
||
|
Note that using **Unix `/` on Windows** works perfectly inside nodejs (and other languages), so there's no reason to stick to the Windows legacy at all.
|
||
|
|
||
|
##### Examples / specs
|
||
|
|
||
|
|
||
|
Check out the different (improved) behavior to vanilla `path`:
|
||
|
|
||
|
`upath.normalize(path)` --returns-->
|
||
|
|
||
|
✓ `'c:/windows/nodejs/path'` ---> `'c:/windows/nodejs/path'` // equal to `path.normalize()`
|
||
|
✓ `'c:/windows/../nodejs/path'` ---> `'c:/nodejs/path'` // equal to `path.normalize()`
|
||
|
✓ `'c:\\windows\\nodejs\\path'` ---> `'c:/windows/nodejs/path'` // `path.normalize()` gives `'c:\windows\nodejs\path'`
|
||
|
✓ `'c:\\windows\\..\\nodejs\\path'` ---> `'c:/nodejs/path'` // `path.normalize()` gives `'c:\windows\..\nodejs\path'`
|
||
|
✓ `'//windows\\unix/mixed'` ---> `'/windows/unix/mixed'` // `path.normalize()` gives `'/windows\unix/mixed'`
|
||
|
✓ `'\\windows//unix/mixed'` ---> `'/windows/unix/mixed'` // `path.normalize()` gives `'\windows/unix/mixed'`
|
||
|
✓ `'////\\windows\\..\\unix/mixed/'` ---> `'/unix/mixed/'` // `path.normalize()` gives `'/\windows\..\unix/mixed/'`
|
||
|
|
||
|
|
||
|
Joining paths can also be a problem:
|
||
|
|
||
|
`upath.join(paths...)` --returns-->
|
||
|
|
||
|
✓ `'some/nodejs/deep', '../path'` ---> `'some/nodejs/path'` // equal to `path.join()`
|
||
|
✓ `'some/nodejs\\windows', '../path'` ---> `'some/nodejs/path'` // `path.join()` gives `'some/path'`
|
||
|
✓ `'some\\windows\\only', '..\\path'` ---> `'some/windows/path'` // `path.join()` gives `'some\windows\only/..\path'`
|
||
|
|
||
|
|
||
|
Parsing with `path.parse()` should also be consistent across OSes:
|
||
|
|
||
|
`upath.parse(path)` --returns-->
|
||
|
|
||
|
✓ `'c:\Windows\Directory\somefile.ext'` ---> `{ root: '', dir: 'c:/Windows/Directory', base: 'somefile.ext', ext: '.ext', name: 'somefile' }`
|
||
|
// `path.parse()` gives `'{ root: '', dir: '', base: 'c:\\Windows\\Directory\\somefile.ext', ext: '.ext', name: 'c:\\Windows\\Directory\\somefile' }'`
|
||
|
✓ `'/root/of/unix/somefile.ext'` ---> `{ root: '/', dir: '/root/of/unix', base: 'somefile.ext', ext: '.ext', name: 'somefile' }` // equal to `path.parse()`
|
||
|
|
||
|
|
||
|
## Added functions
|
||
|
|
||
|
|
||
|
#### `upath.toUnix(path)`
|
||
|
|
||
|
Just converts all `` to `/` and consolidates duplicates, without performing any normalization.
|
||
|
|
||
|
##### Examples / specs
|
||
|
|
||
|
`upath.toUnix(path)` --returns-->
|
||
|
|
||
|
✓ `'.//windows\//unix//mixed////'` ---> `'./windows/unix/mixed/'`
|
||
|
✓ `'..///windows\..\\unix/mixed'` ---> `'../windows/../unix/mixed'`
|
||
|
|
||
|
|
||
|
#### `upath.normalizeSafe(path)`
|
||
|
|
||
|
Exactly like `path.normalize(path)`, but it keeps the first meaningful `./`.
|
||
|
|
||
|
Note that the unix `/` is returned everywhere, so windows `\` is always converted to unix `/`.
|
||
|
|
||
|
##### Examples / specs & how it differs from vanilla `path`
|
||
|
|
||
|
`upath.normalizeSafe(path)` --returns-->
|
||
|
|
||
|
✓ `''` ---> `'.'` // equal to `path.normalize()`
|
||
|
✓ `'.'` ---> `'.'` // equal to `path.normalize()`
|

|
✓ `'./'` ---> `'./'` // equal to `path.normalize()`
|
||
|
✓ `'.//'` ---> `'./'` // equal to `path.normalize()`
|
||
|
✓ `'.\\'` ---> `'./'` // `path.normalize()` gives `'.\'`
|
||
|
✓ `'.\\//'` ---> `'./'` // `path.normalize()` gives `'.\/'`
|
||
|
✓ `'./..'` ---> `'..'` // equal to `path.normalize()`
|
||
|
✓ `'.//..'` ---> `'..'` // equal to `path.normalize()`
|
||
|
✓ `'./../'` ---> `'../'` // equal to `path.normalize()`
|
||
|
✓ `'.\\..\\'` ---> `'../'` // `path.normalize()` gives `'.\..\'`
|
||
|
✓ `'./../dep'` ---> `'../dep'` // equal to `path.normalize()`
|
||
|
✓ `'../dep'` ---> `'../dep'` // equal to `path.normalize()`
|
||
|

|
||
|
✓ `'../path/../dep'` ---> `'../dep'` // equal to `path.normalize()`
|

|
||
|
✓ `'path//dep'` ---> `'path/dep'` // equal to `path.normalize()`
|
||
|

|
||
|
✓ `'./path/dep'` ---> `'./path/dep'` // `path.normalize()` gives `'path/dep'`
|
||
|
✓ `'./path/../dep'` ---> `'./dep'` // `path.normalize()` gives `'dep'`
|
||
|
✓ `'.//windows\\unix/mixed/'` ---> `'./windows/unix/mixed/'` // `path.normalize()` gives `'windows\unix/mixed/'`
|
||
|
✓ `'..//windows\\unix/mixed'` ---> `'../windows/unix/mixed'` // `path.normalize()` gives `'../windows\unix/mixed'`
|
||
|
✓ `'windows\\unix/mixed/'` ---> `'windows/unix/mixed/'` // `path.normalize()` gives `'windows\unix/mixed/'`
|
||
|
✓ `'..//windows\\..\\unix/mixed'` ---> `'../unix/mixed'` // `path.normalize()` gives `'../windows\..\unix/mixed'`
|
||
|
|
||
|
|
||
|
#### `upath.normalizeTrim(path)`
|
||
|
|
||
|
Exactly like `path.normalizeSafe(path)`, but it trims any useless ending `/`.
|
||
|
|
||
|
##### Examples / specs
|
||
|
|
||
|
`upath.normalizeTrim(path)` --returns-->

|
||
|

|
||
|
✓ `'./../dep/'` ---> `'../dep'` // `upath.normalizeSafe()` gives `'../dep/'`

||
|

|
||
|

|
||
|
|
||
|
|
||
|
#### `upath.joinSafe([path1][, path2][, ...])`
|
||
|
|
||
|
Exactly like `path.join()`, but it keeps the first meaningful `./`.
|
||
|
|
||
|
Note that the unix `/` is returned everywhere, so windows `\` is always converted to unix `/`.
|
||
|
|
||
|

## Added functions for *filename extension* manipulation.
|
||
|
|
||
|
**Happy notes:**
|
||
|
|
||
|
In all functions you can:
|
||
|
|
||
|
* use both `.ext` & `ext` - the dot `.` on the extension is always adjusted correctly.
|
||
|
|
||
|
* omit the `ext` param (pass null/undefined/empty string) and the common sense thing will happen.
|
||
|
|
||
|
* ignore specific extensions from being considered as valid ones (eg `.min`, `.dev` `.aLongExtIsNotAnExt` etc), hence no trimming or replacement takes place on them.
|
||
|
|
||
|
|
||
|
|
||
|
#### `upath.addExt(filename, [ext])`
|
||
|
|
||
|
Adds `.ext` to `filename`, but only if it doesn't already have the exact extension.
|
||
|
|
||
|
##### Examples / specs
|
||
|
|
||
|
`upath.addExt(filename, 'js')` --returns-->
|
||
|
|
||
|
✓ `'myfile/addExt'` ---> `'myfile/addExt.js'`
|
||
|
✓ `'myfile/addExt.txt'` ---> `'myfile/addExt.txt.js'`
|
||
|
✓ `'myfile/addExt.js'` ---> `'myfile/addExt.js'`
|
||
|
✓ `'myfile/addExt.min.'` ---> `'myfile/addExt.min..js'`
|
||
|
|
||
|
|
||
|
It adds nothing if no `ext` param is passed.
|
||
|
|
||
|
`upath.addExt(filename)` --returns-->
|
||
|
|
||
|
✓ `'myfile/addExt'` ---> `'myfile/addExt'`
|
||
|
✓ `'myfile/addExt.txt'` ---> `'myfile/addExt.txt'`
|
||
|
✓ `'myfile/addExt.js'` ---> `'myfile/addExt.js'`
|
||
|
✓ `'myfile/addExt.min.'` ---> `'myfile/addExt.min.'`
|
||
|
|
||
|
|
||
|
#### `upath.trimExt(filename, [ignoreExts], [maxSize=7])`
|
||
|
|
||
|
Trims a filename's extension.
|
||
|
|
||
|
* Extensions are considered to be up to `maxSize` chars long, counting the dot (defaults to 7).
|
||
|
|
||
|
* An `Array` of `ignoreExts` (eg `['.min']`) prevents these from being considered as extension, thus are not trimmed.
|
||
|
|
||
|
##### Examples / specs
|
||
|
|
||
|
`upath.trimExt(filename)` --returns-->
|
||
|
|
||
|
✓ `'my/trimedExt.txt'` ---> `'my/trimedExt'`
|
||
|
✓ `'my/trimedExt'` ---> `'my/trimedExt'`
|
||
|
✓ `'my/trimedExt.min'` ---> `'my/trimedExt'`
|
||
|
✓ `'my/trimedExt.min.js'` ---> `'my/trimedExt.min'`
|
||
|
✓ `'../my/trimedExt.longExt'` ---> `'../my/trimedExt.longExt'`
|
||
|
|
||
|
|
||
|
It is ignoring `.min` & `.dev` as extensions, and considers exts with up to 8 chars.
|
||
|
|
||
|
`upath.trimExt(filename, ['min', '.dev'], 8)` --returns-->
|
||
|
|
||
|
✓ `'my/trimedExt.txt'` ---> `'my/trimedExt'`
|
||
|
✓ `'my/trimedExt.min'` ---> `'my/trimedExt.min'`
|
||
|
✓ `'my/trimedExt.dev'` ---> `'my/trimedExt.dev'`
|
||
|
✓ `'../my/trimedExt.longExt'` ---> `'../my/trimedExt'`
|
||
|
✓ `'../my/trimedExt.longRExt'` ---> `'../my/trimedExt.longRExt'`
|
||
|
|
||
|
|
||
|
#### `upath.removeExt(filename, ext)`
|
||
|
|
||
|
Removes the specific `ext` extension from filename, if it has it. Otherwise it leaves it as is.
|
||
|
As in all upath functions, it be `.ext` or `ext`.
|
||
|
|
||
|
##### Examples / specs
|
||
|
|
||
|
`upath.removeExt(filename, '.js')` --returns-->
|
||
|
|
||
|
✓ `'removedExt.js'` ---> `'removedExt'`
|
||
|
✓ `'removedExt.txt.js'` ---> `'removedExt.txt'`
|
||
|
✓ `'notRemoved.txt'` ---> `'notRemoved.txt'`
|
||
|
|
||
|
It does not care about the length of exts.
|
||
|
|
||
|
`upath.removeExt(filename, '.longExt')` --returns-->
|
||
|
|
||
|
✓ `'removedExt.longExt'` ---> `'removedExt'`
|
||
|
✓ `'removedExt.txt.longExt'` ---> `'removedExt.txt'`
|
||
|
✓ `'notRemoved.txt'` ---> `'notRemoved.txt'`
|
||
|
|
||
|
|
||
|
#### `upath.changeExt(filename, [ext], [ignoreExts], [maxSize=7])`
|
||
|
|
||
|
Changes a filename's extension to `ext`. If it has no (valid) extension, it adds it.
|
||
|
|
||
|
* Valid extensions are considered to be up to `maxSize` chars long, counting the dot (defaults to 7).
|
||
|
|
||
|
* An `Array` of `ignoreExts` (eg `['.min']`) prevents these from being considered as extension, thus are not changed - the new extension is added instead.
|
||
|
|
||
|
##### Examples / specs
|
||
|
|
||
|
`upath.changeExt(filename, '.js')` --returns-->
|
||
|
|
||
|
✓ `'my/module.min'` ---> `'my/module.js'`
|
||
|
✓ `'my/module.coffee'` ---> `'my/module.js'`
|
||
|
✓ `'my/module'` ---> `'my/module.js'`
|
||
|
✓ `'file/withDot.'` ---> `'file/withDot.js'`
|
||
|
✓ `'file/change.longExt'` ---> `'file/change.longExt.js'`
|
||
|
|
||
|
|
||
|
If no `ext` param is given, it trims the current extension (if any).
|
||
|
|
||
|
`upath.changeExt(filename)` --returns-->
|
||
|
|
||
|
✓ `'my/module.min'` ---> `'my/module'`

|
✓ `'my/module'` ---> `'my/module'`
|
||
|

|
||
|
✓ `'file/change.longExt'` ---> `'file/change.longExt'`
|
||
|
|
||
|
|
||
|
It is ignoring `.min` & `.dev` as extensions, and considers exts with up to 8 chars.
|
||
|
|
||
|
`upath.changeExt(filename, 'js', ['min', '.dev'], 8)` --returns-->

|
✓ `'file/change.longExt'` ---> `'file/change.js'`
|
||
|
✓ `'file/change.longRExt'` ---> `'file/change.longRExt.js'`
|
||
|
|
||
|
|
||
|
#### `upath.defaultExt(filename, [ext], [ignoreExts], [maxSize=7])`
|
||
|
|
||
|
Adds `.ext` to `filename`, only if it doesn't already have _any_ *old* extension.
|
||
|
|
||
|
* (Old) extensions are considered to be up to `maxSize` chars long, counting the dot (defaults to 7).
|
||
|
|
||
|
* An `Array` of `ignoreExts` (eg `['.min']`) will force adding default `.ext` even if one of these is present.
|
||
|
|
||
|
##### Examples / specs
|
||
|
|
||
|
`upath.defaultExt(filename, 'js')` --returns-->

|
|
||
|
|
||
|
If no `ext` param is passed, it leaves filename intact.
|
||
|
|
||
|
`upath.defaultExt(filename)` --returns-->
|
||
|
|
||
|
✓ `'fileWith/defaultExt'` ---> `'fileWith/defaultExt'`

|
||
|
✓ `'fileWith/defaultExt.longExt'` ---> `'fileWith/defaultExt.longExt'`
|
||
|
|
||
|
|
||
|
It is ignoring `.min` & `.dev` as extensions, and considers exts with up to 8 chars.
