var constantcase = require( '@stdlib/string/constantcase' );
constantcase( str )
Converts a string to constant case.
var str = constantcase( 'foo bar' );
// returns 'FOO_BAR'
str = constantcase( 'foo bar baz' );
// returns 'FOO_BAR_BAZ'
str = constantcase( 'foo_bar' );
// returns 'FOO_BAR'
Examples
var constantcase = require( '@stdlib/string/constantcase' );
var str = 'Hello World!';
var out = constantcase( str );
// returns 'HELLO_WORLD'
str = 'I am a tiny little teapot';
out = constantcase( str );
// returns 'I_AM_A_TINY_LITTLE_TEAPOT'
str = 'with big problems';

// returns 'TO_BE_OR_NOT_TO_BE_THAT_IS_THE_QUESTION'
str = 'isMobile';
out = constantcase( str );

CLI
Usage
Usage: constantcase [options] [<string>]
Options:
-h, --help Print this message.
-V, --version Print the package version.
--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 $'beEp booP\nisMobile' | constantcase --split /\r?\n/ # Escaped... $ echo -n $'beEp booP\nisMobile' | constantcase --split /\\r?\\n/
-
The implementation ignores trailing delimiters.
Examples
$ constantcase 'hello world'
HELLO_WORLD
To use as a standard stream,
$ echo -n 'beEp booP' | constantcase
BEEP_BOOP
To use as a standard stream,
$ echo -n 'isMobile' | constantcase
IS_MOBILE
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 'beep_boop\tisMobile' | constantcase --split '\t'
BEEP_BOOP
IS_MOBILE
