Readme
startsWith
Test if a string starts with the characters of another string.
Installation
To use as a general utility, install the CLI package globally
npm install -g @stdlib/string-starts-with-cli
Usage
Usage: starts-with [options] --search=<string> [<string>]
Options:
-h, --help Print this message.
-V, --version Print the package version.
--search string Search string.
--pos int Search position.
--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 $'Hello, World!\nBeep Boop Baz' | starts-with --search=Beep --split /\r?\n/ # Escaped... $ echo -n $'Hello, World!\nBeep Boop Baz' | starts-with --search=Beep --split /\\r?\\n/
The implementation ignores trailing delimiters.
Examples
$ starts-with --search=be beep
true
To use as a standard stream,
$ echo -n 'boop' | starts-with --search=bo
true
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 'Hello, World!\tBeep Boop' | starts-with --search=Beep --split '\t'
false
true
