How to change the replacement behaviour for dash ("-")

[Vacilando]

Dashes ("-") are simply removed by slugify. We need to have them replaced by something else.

Is the replacement of dashes configurable?

Dashes ("-") are simply removed by slugify.

Can you provide sample code or at least sample input and desired output? That is not the behavior I see. Dashes, at least in the middle of words and with a letter on either side, are preserved as far as I can tell.

> slugify('foo-bar')
'foo-bar'

In our case we have a string like "1952--", so the dashes are at the end.

• The expected output of slugify() is "1952--".
• The actual output is "1952".

[Trott]

By default, slugify will compress multiple occurrences of the separator and will also trim the separator at the start and end of the string.

To suppress the trimming behavior, set trim to false:

> slugify('1952--')
'1952'
> slugify('1952--', { trim: false})
'1952-'
>

That gets you part of the way there, but not quite.

Not sure about slugify on this one, but if using the slug module, you can add - to the charmap and then get the behavior you want:

> slug.charmap['-'] = '-'
'-'
> slug('1952--')
'1952--'

I'm not sure what the equivalent in slugify is but I'd be surprised if there wasn't one somewhere.

If you look at slugify.js line 37 you'll see that each character gets checked against the replacement and if it's the same it gets replaced with a space.

If you pass josh- to slugify and replacement: '-' then you'll get josh as the output.

I'm running into this issue right now where I want - to be the replacement, but I don't want it to be replaced with a space

Those spaces get turned into dashes again. I don't understand the problem you're describing. This seems to work as expected:

console.log(slugify('josh-', {trim: false})) // 'josh-'

[joshuabyler]

I'll double check and make sure this is still happening, hopefully the trim: false is the change I need to make

[stevenwoodson]

Here's another scenario to consider, if you pass either step -1 or step 1 you'll get step-1 as the response.

It'd be nice to have an option not to automatically replace instances of the replacement option with a space so we can choose to get step--1 for step -1 and step-1 for step 1 in the same example noted above. This will help avoid collisions of the same response from potentially different inputs.

mw we switched to sindresorhus/slugify where we can preserveCharacters: ['--'] in options
