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!

NPM version Build Status Coverage Status

Return the next extended grapheme cluster break in a string after a specified position.

Installation

npm install @stdlib/string-next-grapheme-cluster-break

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 nextGraphemeClusterBreak = require( '@stdlib/string-next-grapheme-cluster-break' );

nextGraphemeClusterBreak( string[, fromIndex] )

Returns the next extended grapheme cluster break in a string after a specified position.

var out = nextGraphemeClusterBreak( 'last man standing' );
// returns 1

By default, the function searches for a grapheme cluster break starting from the first index. To specify an alternative starting search index, provide a fromIndex argument.

var out = nextGraphemeClusterBreak( 'last man standing', 4 );
// returns 5

Notes

  • If string is an empty string, the function returns -1 irrespective of fromIndex.
  • If an extended grapheme cluster break does not exist after fromIndex, the function returns -1.
  • Note that fromIndex does not refer to a visual character position, but to an index in the ordered sequence of UTF-16 code units.

Examples

var nextGraphemeClusterBreak = require( '@stdlib/string-next-grapheme-cluster-break' );

var out = nextGraphemeClusterBreak( 'last man standing', 4 );
// returns 5

out = nextGraphemeClusterBreak( 'presidential election', 8 );
// returns 9

out = nextGraphemeClusterBreak( 'अनुच्छेद', 1 );
// returns 3

out = nextGraphemeClusterBreak( '🌷', 0 );
// returns -1

CLI

Installation

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

npm install -g @stdlib/string-next-grapheme-cluster-break-cli

Usage

Usage: next-grapheme-cluster-break [options] [<string>]

Options:

  -h,    --help                Print this message.
  -V,    --version             Print the package version.
         --from index          Starting search position in string. Default: 0.

Examples

$ next-grapheme-cluster-break --from=1 अनुच्छेद
3

To use as a standard stream,

$ echo -n 'अनुच्छेद' | next-grapheme-cluster-break --from=1
3
