So, again, why did I write the EBNF grammar for AWK?

Basically, I have two ongoing projects where AWK is involved. Firs is Squawk, and implementation of AWK and second is AWK2c, which obviously translates AWK to C.

Plus, I am thinking of making a Github page called 'The Internet Grammar Database' where I would post EBNF, Yacc, PEG, Lex, definitions of languages. However, I don't have much experience in web development, so if you can help me, let me know (chubakbidpaa [at] riseup [dot] net).

So anyways, awk.ebnf contains the EBNF grammar for AWK. Some considerations:

Chubek

c.ebnf contains grammar ofr C99. Note that this is ANSI C, not ISO C, so there are some omissions. The reason I wrote this is, I am currently writing a C compiler, with my own backend (and hopefully, frontend) in OCaml. And I needed to collect the grammar in one place.

How to Read EBNF Grammars?

Reading EBNF grammars is pretty simple:

• Enclosed within two ?s is a global capture, it does not mean optional. It means 'I am writing a free-style sentence'.
• Enclosed within { and } means : repeat at least zero times
• Enclosed within [ and ] means : this is optional
• Enclosed within ( and ) means : this is a group

All American Regex

(Credit card # validation regular expression)

The regex \b(?:\d[ -]*?){13,16}\b is a powerful tool used for validating credit card numbers. Credit card numbers typically consist of a sequence of 13 to 16 digits, with optional spaces or dashes in between. This regular expression applies the Luhn algorithm to ensure the validity of credit card numbers by checking for the correct number of digits and the proper formatting. By using this regular expression, developers can easily implement credit card number validation in their applications, helping to enhance security and prevent errors during data entry.

ANSI escape sequences

ANSI escape sequences can be printed to a shell to as instructions. The below is a list of codes I have used often in my CLI programs and I find myself looking up over and over again.

A great article about it can be found here.
