Test if a value is an alphagram.
var isAlphagram = require( '@stdlib/assert/is-alphagram' );Tests if a value is an alphagram (i.e., a sequence of characters arranged in alphabetical order).
var value = 'beep';
var bool = isAlphagram( value );
// returns true- The function first checks that an input
valueis astringbefore validating that thevalueis an alphagram. For non-string values, the function returnsfalse.
var isAlphagram = require( '@stdlib/assert/is-alphagram' );
var out = isAlphagram( 'beep' );
// returns true
out = isAlphagram( new String( 'beep' ) );
// returns true
out = isAlphagram( '' );
// returns false
out = isAlphagram( 'zba' );
// returns false
out = isAlphagram( 123 );
// returns falseUsage: is-alphagram [options] [<string>]

--split sep Delimiter for stdin data. Default: '/\\r?\\n/'.
-
If the split separator is a regular expression, ensure that the
splitoption is either properly escaped or enclosed in quotes.# Not escaped... $ echo -n $'beep\nhello' | is-alphagram --split /\r?\n/ # Escaped... $ echo -n $'beep\nhello' | is-alphagram --split /\\r?\\n/
-
The implementation ignores trailing delimiters.
$ is-alphagram beep
trueTo use as a standard stream,
$ echo -n 'hello' | is-alphagram
falseBy default, when used as a standard stream, the implementation assumes newline-delimited data. To specify an alternative delimiter, set the split option.
$ echo -n 'beep\thello' | is-alphagram --split '\t'
true
