+# 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()`

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

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

+        ✓ `'path//dep'`                      --->                   `'path/dep'`  // equal to `path.normalize()`
+        ✓ `'./dep'`                          --->                      `'./dep'`  // `path.normalize()` gives `'dep'`
+        ✓ `'./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'`    --->              `'../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-->
+
+        ✓ `'./'`                          --->                         `'.'`  // `upath.normalizeSafe()` gives `'./'`
+        ✓ `'./../'`                       --->                        `'..'`  // `upath.normalizeSafe()` gives `'../'`

+
+#### `upath.joinSafe([path1][, path2][, ...])`
+
+Exactly like `path.join()`, but it keeps the first meaningful `./`.

+
+        ✓ `'some/nodejs/deep', '../path'`                --->           `'some/nodejs/path'`  // equal to `path.join()`

+    
+
+## 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'`

+        ✓ `'file/change.longExt'`      --->      `'file/change.longExt.js'`
+        
+
+If no `ext` param is given, it trims the current extension (if any).

+          ✓ `'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.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

+        
+
+If no `ext` param is passed, it leaves filename intact.
