N.A.N.Y. 2019: libvldmail: Your friendly e-mail address validation library.

[Tuxman]

Just throwing together my other 2019 applications before writing new ones...

NANY 2019 Entry Information

Application Name	libvldmail
Version	0.1.1
Short Description	A library that can validate e-mail addresses according to RFC 6531 with a fallback to RFC 5321 ff.
Supported OSes	Any, I hope.
Web Page	https://www.donationcoder.com/forum/index.php?topic=45118
Download Link	None, actually. This is a library, it needs to be integrated with your own applications...
System Requirements	You will need a C compiler. Nothing else.
Version History	0.1.1 [2018-02-25]: - Introducing the BREAK_LOOP_FAIL macro. (Thank you, stsc.) - Improved output of one of the validation messages. 0.1.0 [2018-02-24]: - Initial version.
Author	when in doubt, me

Description
Your friendly e-mail address validation library.

Features
- Can validate e-mail addresses.
- Comes with a test

Usage
Using the Application

You can use libvldmail from inside your own applications.
Example code (C):

Code

    #include <vldmail.h>
    
    int main(void) {
        /* ... your code ... */
        
        vldmail validator = validate_email(L"foo@bar.quux");
        if (0 == validator.success) {
            /* success == 0 means that something was wrong. */
            printf(L"Validating foo@bar.quux failed: %ls\n", validator.message);
        }
        
        /* ... more of your code ... */
    }

Uninstallation
Just remove it, I guess.

Code

    #include <vldmail.h>
    
    int main(void) {
        /* ... your code ... */
        
        vldmail validator = validate_email(L"foo@bar.quux");
        if (0 == validator.success) {
            /* success == 0 means that something was wrong. */
            printf(L"Validating foo@bar.quux failed: %ls\n", validator.message);
        }
        
        /* ... more of your code ... */
    }

Does your library perform online check to see if its valid or how does it work?

[Tuxman]

No, it is a complete offline implementation of the RFCs. It basically parses the string according to given rules.

[KodeZwerg]

Will you later integrate at least a "does domain exists" function or will it never evolve to such?
Thank you for answering Mr. Tuxman.

[Tuxman]

That would not make sense as the RFCs don't require the "domain" part to be a registered and reachable domain. Additionally, the application which uses the library does not have to access the internet at all.

There are libraries for that.

There are libraries for that.

Okay, thank you again for answering.
