What is the reason because is removing - and _ from the begging and the end of the name. I want to represent an endpoint for a item that is named ______. How to do it in your case?

Real example: Magic The Gathering card

Debug to understand why tests are passing if 'trSub' is not added in init?

Hello,

Can you please tag and version this project?

I am the Debian Maintainer for slug and versioning would help Debian keep up with development.

This code panics:

slug.Make("𐀀")

This is due to the internal use of rainycape/unidecode, which can not handle Unicode character U+10000, see rainycape/unidecode#8.

Given the inactivity of the upstream package, it might be worth filtering out the character in question before passing it to unidecode.

When using the truncate function, the slug can be longer than MaxLength on specific conditions. See this example:

• original string (of length 11): "abcde-fghij"
• MaxLength: 10
• expected string: "abcde"
• output string: "abcde-fghij"

Current function fails on this edge case because the last word doesn't end with a "-" during the max length test here so the - 1 is wrongfully applied.

This seems like a silly use case at first, but when creating a slug from a string containing emojis or pictograms, there is no representation of those characters. For example:

slug.Make("🐛")
slug.Make("☺")
slug.Make("𝕗𝕒𝕟𝕔𝕪 𝕥𝕖𝕩𝕥")

all yield empty strings.

I'm not sure how such a character would best be represented in a slug, but simply removing them could be problematic in some cases. Is this intentional?

Looks like default substitutions are not running for some langs:

More tests needed and fixing it in a way that will not force adding every lang by hand.

When trying to truncate a string with a value greater than its size, we get the below error.

Example of failed test: {"DOBROSLAWZYBORT", 17, "dobroslawzybort", false}

--- FAIL: TestSlugMakeSmartTruncate (0.01s)
panic: runtime error: slice bounds out of range [:17] with length 15 [recovered]
	panic: runtime error: slice bounds out of range [:17] with length 15

It fails about 12% of the time for me:

--- FAIL: TestSubstituteLang (0.00s)
    slug_test.go:155: 1. Substitute("o a o", map[string]string{"o":"no", "a":"or"}) = "no nor no"; want "no or no"
FAIL

text := slug.Make("Hellö Wörld & хелло ворлд")
fmt.Println(text) // Will print: "hello-world-(and)-khello-vorld"

correct
fmt.Println(text) // Will print: "hello-world-khello-vorld"

For German, @ is replaced with en. I am a native speaker, and I have never heard of read this “en”. Where does it come from? It is mostly called “at” in German (as in English). Other Geman words for it are very long.

getting- started ## should become getting-started

How to achieve this ?

When something new is added there should be info if it's tested properly.

As it exists the validation for MaxLength of a slug, I thought it sould exists MinLength also.

The 2 main functions in which this will affect are MakeLang (Make uses it so no need for it) and IsSlug.

For IsSlug it's easy, it's just a validation and if not then return false.
For MakeLang is more complex as the current signature does not return an error, and changing that would be a HUGE change on the API, so not an option, the other options would be:

• Fill the missing characters with something, maybe defined by the user on another var
• Only use it on the IsSlug and not on the MakeLang

WDYT?

Hello,

Please update to latest the import path for unidecode to: github.com/rainycape/unidecode. See: https://github.com/rainycape/unidecode

It would be awesome if there's a function that checks whether an input string is a valid slug or not like this one: https://github.com/extemporalgenome/slug/blob/master/slug.go#L94

IDK exatly if it's a bug or it's supose to be this way really hehe.

package main

import (
        "fmt"

        "github.com/gosimple/slug"
)

func main() {
        text := ""
        fmt.Printf("IsSlug: %t\n", slug.IsSlug(text))
}

the output is:

IsSlug: true

IMO an empty string should not be considred a slug but before opening a PR I wanted to know if it should be 😄

Is there any way we could have it auto detect the language with the slug.Make and then default to English?

Would be great if there was an option to allow uppercase characters to not be converted.

Thanks!

Hi there! Thanks for this awesome lib!
I'm not sure if this is a valid use-case or not, but I've found a set of custom substitutions that seem to break Make().
In the code below, IsSlug() returns false for every item in slugs.

names := []string{
	"Ciudad Autónoma de Buenos Aires AR",
	"Córdoba AR",
	"Entre Ríos AR",
	"Neuquén AR",
	"Tucumán AR",
}

slug.CustomSub = map[string]string{
	"AR": "",
	"BR": "",
	"CL": "",
	"UY": "",
}

slug.CustomRuneSub = map[rune]string{
    'á': "aa",
    'é': "ee",
    'í': "ii",
    'ó': "oo",
    'ú': "uu",
    ' ': "_",
}

var slugs []string

for _, n := range names {
	slugs = append(slugs, slug.Make(n))
}

I've already found a way to work around this in my code, using SubstituteRune() first.
