truncateMiddle
Truncate a string in the middle to a specified length.
Installation
To use as a general utility, install the CLI package globally
npm install -g @stdlib/string-truncate-middle-cli
Usage
Usage: truncate-middle [options] [<string>] --len <length>
Options:
-h, --help Print this message.
-V, --version Print the package version.
--len length String length.
--seq str Custom replacement sequence. Default: '...'.
--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' | truncate-middle --len 6 --split /\r?\n/ # Escaped... $ echo -n $'Hello, World!\nBeep Boop Baz' | truncate-middle --len 6 --split /\\r?\\n/
The implementation ignores trailing delimiters.
Examples
$ truncate-middle 'Hello, World!' --len 8
Hel...d!
$ truncate-middle 'Hello, World!' --len 6 --seq '!'
Hel|d!
To use as a standard stream,
$ echo -n 'Hello, World!' | truncate-middle --len 8
Hel...d!
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' | truncate-middle --split '\t' --len 6 --seq '!'
Hel|d!
Bee|op
