An option to add a space either side of the ellipsis would be nice. thanks

Currently it's truncated at the end, but an option could enable truncating at the start or in the middle.

Not something I need right now, but might be useful in the future.

A good pull request would be much welcome :)

Hello,

I just installed this package, which by the way, seems to be the only one that does truncation and is currently maintained.

However, I have an issue while using this package inside my Next.Js application (in Typescript).

Here is how I import the package :

import cliTruncate from "cli-truncate";
// I also tried
import * as cliTruncate from "cli-truncate";

And here is the error on runtime:

Error: Must use import to load ES Module: D:\workspace\my-app\node_modules\cli-truncate\index.js
require() of ES modules is not supported.
require() of D:\workspace\my-app\node_modules\cli-truncate\index.js from D:\workspace\my-app\packages\website\.next\server\pages\blog.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from D:\workspace\my-app\node_modules\cli-truncate\package.json.

Do you have any idea why is this happening?

This PR adds an option ellipsis that allows the user to replace the default … with another character.

Example:

import cliTruncate from 'cli-truncate';

// Without option
cliTruncate('unicorns', 5, {position: 'end'});
//=> 'unic…'

// With option set to '.'
cliTruncate('unicorns', 5, {position: 'end', ellipsis: '.'});
//=> 'unic.'

// With option set to ''
cliTruncate('unicorns', 5, {position: "end", ellipsis: ''});
//=> 'unico'

Includes type definitions and documentation.

Closes #18

just finding a space within next 3 characters form actual breeaking point. If the string has to be truncated from start then it searches towards left and if the string has to be truncated from end then it searched towards right, so that the length of the truncated string is not more than the columns argument passed.

some changes to the code were done by xo --fix (xo asked for them) like doing destructuring.

Fixes #8

Depends on https://github.com/chalk/wrap-ansi/issues/10 and https://github.com/chalk/wrap-ansi/issues/11.

Note to self: Update the readme description when this is fixed.

Object rest operator was introduced in ES2018, and was not fully supported in Node.js 8 until 8.6.0: https://node.green/#ES2018-features-object-rest-spread-properties

Hope we can keep compatibility with all the Node.js 8 version. We can revert this commit when we drop support of Node.js 8.

Hi,

in cliTruncate( chalk.gray( someLongFileName ), process.stdout.columns, { position: 'middle' } ) the ellipsis color is white (not gray).

Better having a color property in the options, like { position: 'middle', color: 'gray' } ?

Note: tested only on Win10

Current library uses ES6 code in main output file. Safari 10.11.* (El Captain) does not support ES6 "const" in "strict mode" (as well as arrow functions). Original console error message: "Const declarations are not supported in strict mode".

On "prepublish" command I suggest transpile all ES6 code (include node_modules) to ES5, minify and make ES5 /lib/bundle.js as a main library file (for NPM). In github ES6 source code will be available in /src folder.

This is a great tool, but the one thing preventing me from using it the fact that in my use case i'd like the text to be truncated w/o an ellipsis.

Could we have an option truncateChar or so that allows us replace the ellipsis with another character (or none at all)?

Reproduction from the readme:

cliTruncate('unicorn', 4);
//=> 'un…', not 'uni…'

Can be reproduced without any changes by pulling a fresh clone of this repository and running npm test.

❯ npm t

> [email protected] test
> xo && ava && tsd


  main

  Difference:

  - 'un…'
  + 'uni…'

  › file://test.js:5:4



  space option

  Difference:

  - 'un …'
  + 'uni …'

  › file://test.js:25:4

I reverted https://github.com/sindresorhus/cli-truncate/commit/23b40dc576d53f83a88caa2001ce5341d9f3241c locally and tests are passing now, so it has to be a regression from https://github.com/sindresorhus/cli-truncate/pull/19. cc @codemaster138

It'd be cool, although probably a bit unnecessary and overcomplicated, if for example when truncating at the end the style of the character preceding the ellipses is detected and the ellipsis is written using the same style.
