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 <!-- dependencies -->

Replace the substring before the first occurrence of a specified search string.

## Installation ```bash npm install @stdlib/string-replace-before ``` Alternatively, - To load the package in a website via a `script` tag without installation and bundlers, use the [ES Module][es-module] available on the [`esm`][esm-url] branch (see [README][esm-readme]). - If you are using Deno, visit the [`deno`][deno-url] branch (see [README][deno-readme] for usage intructions). - For use in Observable, or in browser/node environments, use the [Universal Module Definition (UMD)][umd] build available on the [`umd`][umd-url] branch (see [README][umd-readme]). - To use as a general utility for the command line, install the corresponding [CLI package][cli-section] globally. The [branches.md][branches-url] 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 ```javascript var replaceBefore = require( '@stdlib/string-replace-before' ); ``` #### replaceBefore( str, search, replacement ) Replaces the substring before the first occurrence of a specified search string. ```javascript var out = replaceBefore( 'beep boop', ' ', 'loop' ); // returns 'loop boop' out = replaceBefore( 'beep boop', 'o', 'bar' ); // returns 'baroop' ```
## Notes - If a search string is not present in a provided string, the function returns the provided string unchanged. - If a search string is an empty string, the function returns the provided string unchanged.
## Examples ```javascript var replaceBefore = require( '@stdlib/string-replace-before' ); var out = replaceBefore( 'beep boop', 'p', 'see' ); // returns 'seep boop' out = replaceBefore( 'Hello World!', 'xyz', 'foo' ); // returns 'Hello World!' out = replaceBefore( 'Hello World!', '', 'foo' ); // returns 'Hello World!' out = replaceBefore( '', 'xyz', 'foo' ); // returns '' ```
## CLI
## Installation To use as a general utility, install the CLI package globally ```bash npm install -g @stdlib/string-replace-before-cli ```
### Usage ```text Usage: replace-before [options] --search= --replacement= [] Options: -h, --help Print this message. -V, --version Print the package version. --search string Search string. --replacement string Replacement string. --split sep Delimiter for stdin data. Default: '/\\r?\\n/'. ```
### Notes - If the split separator is a [regular expression][mdn-regexp], ensure that the `split` option is either properly escaped or enclosed in quotes. ```bash # Not escaped... $ echo -n $'foo\nbar\nbaz' | replace-before --search a --replacement b --split /\r?\n/ # Escaped... $ echo -n $'foo\nbar\nbaz' | replace-before --search a --replacement b --split /\\r?\\n/ ``` - The implementation ignores trailing delimiters.
### Examples ```bash $ replace-before abcdefg --search d --replacement pqr pqrdefg ``` To use as a [standard stream][standard-streams], ```bash $ echo -n $'beep\nboop' | replace-before --search p --replacement see seep seep ``` By default, when used as a [standard stream][standard-streams], the implementation assumes newline-delimited data. To specify an alternative delimiter, set the `split` option. ```bash $ echo -n 'beep\tboop' | replace-before --search p --replacement see --split '\t' seep seep ```
