About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Convert Path

Convert between POSIX and Windows paths.

Installation

npm install @stdlib/utils-convert-path

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
• If you are using Deno, visit the deno branch (see README for usage intructions).
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).
• To use as a general utility for the command line, install the corresponding CLI package globally.

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

var convertPath = require( '@stdlib/utils-convert-path' );

convertPath( from, to )

Converts between POSIX and Windows paths.

var p = convertPath( 'C:\\foo\\bar', 'posix' );
// returns '/c/foo/bar'

The following output path conventions are supported:

• win32: Windows path convention; e.g., C:\\foo\\bar.
• mixed: mixed path convention (Windows volume convention and POSIX path separator); e.g., C:/foo/bar.
• posix: POSIX path convention; e.g., /c/foo/bar.

Notes

• A Windows extended-length path cannot be converted to either a mixed or posix path convention, as forward slashes cannot be used as path separators.
• If a POSIX path begins with /[A-Za-z]/ (e.g., /c/), the path is assumed to begin with a volume name.
• The function makes no attempt to verify that a provided path is valid.

Examples

var convertPath = require( '@stdlib/utils-convert-path' );

var p1;
var p2;

p1 = '/c/foo/bar/beep.c';
p2 = convertPath( p1, 'win32' );
// returns 'c:\foo\bar\beep.c'

p1 = '/c/foo/bar/beep.c';
p2 = convertPath( p1, 'mixed' );
// returns 'c:/foo/bar/beep.c'

p1 = '/c/foo/bar/beep.c';
p2 = convertPath( p1, 'posix' );
// returns '/c/foo/bar/beep.c'

p1 = 'C:\\\\foo\\bar\\beep.c';
p2 = convertPath( p1, 'win32' );
// returns 'C:\\foo\bar\beep.c'

p1 = 'C:\\\\foo\\bar\\beep.c';
p2 = convertPath( p1, 'mixed' );
// returns 'C:/foo/bar/beep.c'

p1 = 'C:\\\\foo\\bar\\beep.c';
p2 = convertPath( p1, 'posix' );
// returns '/c/foo/bar/beep.c'

CLI

Installation

To use as a general utility, install the CLI package globally

npm install -g @stdlib/utils-convert-path-cli

Usage

Usage: convert-path [options] [<path>] --out=<output>

Options:

  -h,    --help                Print this message.
  -V,    --version             Print the package version.
  -o,    --out output          Output path convention.
         --split sep           Delimiter for stdin data. Default: '/\\r?\\n/'.

Notes

• If the split separator is a regular expression, ensure that the split option is either properly escaped or enclosed in quotes.

  # Not escaped...
  $ echo -n $'c:/foo/bar\n./docs/eslint' | convert-path --out=posix --split /\r?\n/
  # Escaped...
  $ echo -n $'c:/foo/bar\n./docs/eslint' | convert-path --out=posix --split /\\r?\\n/

• The implementation ignores trailing delimiters.

Examples

$ convert-path /c/foo/bar --out=mixed
c:/foo/bar

To use as a standard stream,

$ echo -n '/c/foo/bar' | convert-path --out=win32
c:\foo\bar

By default, when used as a standard stream, the implementation assumes newline-delimited data. To specify an alternative delimiter, set the split option.

$ echo -n 'c:/foo/bar\t./docs/eslint' | convert-path  --out=win32 --split '\t'
c:\foo\bar
.\docs\eslint
