isAlpha enhancement #1286

resolve #1282

profnandaa

This so far looks good to me, thanks for getting this quick.

Just one thing you forgot, could you update the README too.

mum-never-proud · 2020-04-25T02:10:38Z

@profnandaa thanks for the review, but I see one problem with the above implementation.

since we are allowing the user to pass strings, there are chances that the user might pass some invalid regex characters and the code might break.

we may also experience regex weird behavior, one of the examples is try adding
'h.e.-llo'.replace(/[ -\/]/g, '') paste it in the dev tools you will see that it will also remove dots from the word

so my proposal for strings is to go with the below code

ignore.split('').forEach(ignoredCharacter => str = str.split(ignoredCharacter))

with little tweaks, this code should work but at least it's safe and I hope it gives you the rough idea on what it's doing

validator.js/es/lib/isAlpha.js

Lines 12 to 13 in 5ff4998

    
           } else if (typeof ignore === 'string') { 
        
             str = str.replace(new RegExp("[".concat(ignore, "]"), 'g'), '');

ping @profnandaa

profnandaa · 2020-04-28T08:14:46Z

@mum-never-proud -- I see, nice catch. What if we limited the ignore chars that we support? Pragmatically, I think we should support only the known in-between characters for words, i.e. space, ' and -; Have I left anything?

mum-never-proud · 2020-04-28T14:56:54Z

@profnandaa but again we are narrowing down the use cases, some may raise an issue saying he needs to ignore a back tick or @

it's better to support all the characters in order to avoid reworking for additions

your thoughts?

mum-never-proud · 2020-05-05T03:09:43Z

pong @profnandaa

profnandaa · 2020-05-05T18:30:22Z

@mum-never-proud - makes sense. How about if just support a string with a list of characters to ignore; but not regex for now?

mum-never-proud · 2020-05-06T12:16:36Z

@profnandaa but anyhow we will be using regex to check right?

mum-never-proud · 2020-05-14T11:23:56Z

pong @profnandaa

profnandaa · 2020-05-19T20:41:43Z

@mum-never-proud -- sure, still use regex to check, but don't take regex option from users.

mum-never-proud · 2020-05-29T03:55:41Z

@profnandaa i think we can allow both string and regex, i guess the key solution here will be to escape the regex for string which seemed to work

let me know your thoughts

ps: let me know if you are fin with the approach, so that i can do one final optimization of not modifying the params directly, a bad practice

profnandaa · 2020-05-29T12:17:55Z

@mum-never-proud -- I'm okay with this, thanks.

mum-never-proud · 2020-05-29T13:10:26Z

@profnandaa done,

profnandaa

LGTM You can update the README too?

mum-never-proud · 2020-05-29T15:03:49Z

cool, thanks!

mind providing text?

kinda stuck here

options is optional, valid option is ignore which can either be a String or RegExp to ignore certain characters

anything better than this?

@profnandaa

profnandaa · 2020-05-29T18:11:54Z

I could re-jig it to be similar to the rest, something like:

options is an optional object that can be supplied with the following key(s): ignore which can either be a String or RegExp of characters to be ignored e.g. " -" will ignore spaces and -'s.

mum-never-proud · 2020-05-30T01:03:22Z

@profnandaa done!

profnandaa

Thanks! LGTM 🎉

profnandaa · 2020-05-30T07:21:04Z

In case I have missed anything, I will appreciate a second look from @ezkemboi @tux-tn or @rubiin

profnandaa · 2020-06-13T20:21:59Z

ping @tux-tn -- can review please before @mum-never-proud fixes the merge conflicts...

ezkemboi · 2020-07-04T17:02:12Z

src/lib/isAlpha.js

+  assertString(_str);
+
+  let str = _str;
+  const { ignore } = options;


I am with the opinion that ignore characters should be optional.
This actually fails if a user does not pass ignore values (It is not guaranteed that a user needs to have some values ignored).
Also, if I pass options as args: [{ ignore: /[\s/-]/g }], it will fail or I do pass an args: ['en-US', { }] it also fails.
I am open to discussion on way forward.

Cc. @profnandaa

hmm technically i don't see a possibility of failing for any of the above args, may be i can add those

validator.js/src/lib/isAlpha.js

Lines 8 to 10 in a919d99

const { ignore } = options;

if (ignore) {

the above line says that ignore is optional which means, args: ['en-US', { }] should pass

as far as about this [{ ignore: /[\s/-]/g }] we are already asserting first argument to be string

let me know if it makes sense @profnandaa @ezkemboi

ezkemboi

LGTM, just check my comment @mum-never-proud and resolve conflicts.

ezkemboi · 2020-09-28T17:06:14Z

-export default function isAlpha(str, locale = 'en-US') {

I am just curious why change str to _str and later do

let str = _str

I thought we could pass str as before and do:

assertString(str);

But, all in all, it looks good to me.

@ezkemboi ah it's not good practice to directly change the arguments, just following best practices, will resolve the conflict in sometime

Hey, I'm getting an error in typescript (but it is working and validates)

body('field').isAlpha('en-US', {ignore: ' '})

(property) IsAlphaOptions.ignore?: string[] | undefined
Type 'string' is not assignable to type 'string[] | undefined'.ts(2322)

A string[] does not work

body('field').isAlpha('en-US', {ignore: [' ']})

Error: ignore should be instance of a String or RegExp

Am I missing something?

profnandaa · 2020-12-14T10:13:39Z

Yes, ignore is not an [array], should be a "string" or /regex/ Are the docs saying otherwise? ./na

Was looking at the docs here https://github.com/validatorjs/validator.js#validators, hard to see what is the key(s) there.

In options.d.ts

export interface IsAlphaOptions { ignore?: string[]; }

Should be just a string ?

Nice that it works now otherwise.
