| # upath v1.2.0 |
| |
| [](https://travis-ci.org/anodynos/upath) |
| [](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'` ---> `'../path/dep'` // equal to `path.normalize()` |
| ✓ `'../path/../dep'` ---> `'../dep'` // 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/'` ---> `'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 `'../'` |
| ✓ `'./../dep/'` ---> `'../dep'` // `upath.normalizeSafe()` gives `'../dep/'` |
| ✓ `'path//dep\\'` ---> `'path/dep'` // `upath.normalizeSafe()` gives `'path/dep/'` |
| ✓ `'.//windows\\unix/mixed/'` ---> `'./windows/unix/mixed'` // `upath.normalizeSafe()` gives `'./windows/unix/mixed/'` |
| |
| |
| #### `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 `/`. |
| |
| ##### Examples / specs & how it differs from vanilla `path` |
| |
| `upath.joinSafe(path)` --returns--> |
| |
| ✓ `'some/nodejs/deep', '../path'` ---> `'some/nodejs/path'` // equal to `path.join()` |
| ✓ `'./some/local/unix/', '../path'` ---> `'./some/local/path'` // `path.join()` gives `'some/local/path'` |
| ✓ `'./some\\current\\mixed', '..\\path'` ---> `'./some/current/path'` // `path.join()` gives `'some\current\mixed/..\path'` |
| ✓ `'../some/relative/destination', '..\\path'` ---> `'../some/relative/path'` // `path.join()` gives `'../some/relative/destination/..\path'` |
| |
| |
| ## 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.coffee'` ---> `'my/module'` |
| ✓ `'my/module'` ---> `'my/module'` |
| ✓ `'file/withDot.'` ---> `'file/withDot'` |
| ✓ `'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--> |
| |
| ✓ `'my/module.coffee'` ---> `'my/module.js'` |
| ✓ `'file/notValidExt.min'` ---> `'file/notValidExt.min.js'` |
| ✓ `'file/notValidExt.dev'` ---> `'file/notValidExt.dev.js'` |
| ✓ `'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--> |
| |
| ✓ `'fileWith/defaultExt'` ---> `'fileWith/defaultExt.js'` |
| ✓ `'fileWith/defaultExt.js'` ---> `'fileWith/defaultExt.js'` |
| ✓ `'fileWith/defaultExt.min'` ---> `'fileWith/defaultExt.min'` |
| ✓ `'fileWith/defaultExt.longExt'` ---> `'fileWith/defaultExt.longExt.js'` |
| |
| |
| If no `ext` param is passed, it leaves filename intact. |
| |
| `upath.defaultExt(filename)` --returns--> |
| |
| ✓ `'fileWith/defaultExt'` ---> `'fileWith/defaultExt'` |
| ✓ `'fileWith/defaultExt.js'` ---> `'fileWith/defaultExt.js'` |
| ✓ `'fileWith/defaultExt.min'` ---> `'fileWith/defaultExt.min'` |
| ✓ `'fileWith/defaultExt.longExt'` ---> `'fileWith/defaultExt.longExt'` |
| |
| |
| It is ignoring `.min` & `.dev` as extensions, and considers exts with up to 8 chars. |
| |
| `upath.defaultExt(filename, 'js', ['min', '.dev'], 8)` --returns--> |
| |
| ✓ `'fileWith/defaultExt'` ---> `'fileWith/defaultExt.js'` |
| ✓ `'fileWith/defaultExt.min'` ---> `'fileWith/defaultExt.min.js'` |
| ✓ `'fileWith/defaultExt.dev'` ---> `'fileWith/defaultExt.dev.js'` |
| ✓ `'fileWith/defaultExt.longExt'` ---> `'fileWith/defaultExt.longExt'` |
| ✓ `'fileWith/defaultExt.longRext'` ---> `'fileWith/defaultExt.longRext.js'` |
