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!
Return the error identifier prefix associated with a specified package name.
npm install @stdlib/error-tools-pkg2id
Alternatively,
- To load the package in a website via a
script
tag without installation and bundlers, use the ES Module available on theesm
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.
var pkg2id = require( '@stdlib/error-tools-pkg2id' );
Returns the error identifier prefix associated with a specified package name.
var v = pkg2id( '@stdlib/math-base-special-sin' );
// returns '0YK'
If provided an unrecognized pkg
, the function returns null
.
var v = pkg2id( 'unrecognized_pkg_beep_boop_bop_bip' );
// returns null
-
The function supports providing both internal and standalone package names.
var v = pkg2id( '@stdlib/math-base-special-sin' ); // returns '0YK'
var formatProdErrorMessage = require( '@stdlib/error-tools-fmtprodmsg' );
var pkg2id = require( '@stdlib/error-tools-pkg2id' );
var prefix = pkg2id( '@stdlib/math-base-special-sin' );
var errorCode = '23';
var code = prefix + errorCode;
var msg = formatProdErrorMessage( code );
console.log( msg );
// => <string>
To use as a general utility, install the CLI package globally
npm install -g @stdlib/error-tools-pkg2id-cli
Usage: stdlib-pkg2id [options] error-tools-pkg2id
Options:
-h, --help Print this message.
-V, --version Print the package version.
$ stdlib-pkg2id '@stdlib/math-base-special-sin'
0YK
