✨ form_variables(3X) ✨

okay bestie, so this is a library calls page from the ncurses crew, and it's all about the form system's global variables. iykyk. let's get into it 💖

🌸 NAME 🌸

TYPE_ALNUM, TYPE_ALPHA, TYPE_ENUM, TYPE_INTEGER, TYPE_IPV4, TYPE_NUMERIC, TYPE_REGEXP — these are the form system's global variables, and they are lowkey iconic 💅

FIELDTYPE * TYPE_ALNUM;
FIELDTYPE * TYPE_ALPHA;
FIELDTYPE * TYPE_ENUM;
FIELDTYPE * TYPE_INTEGER;
FIELDTYPE * TYPE_IPV4;
FIELDTYPE * TYPE_NUMERIC;
FIELDTYPE * TYPE_REGEXP;

💜 DESCRIPTION 💜

okay so these are literally the building blocks of the form library 🧱✨ they define the fields you can create using the form_fieldtype(3X) functions. each one brings its own lil validation squad — functions for field-validation AND character-validation — all according to the datatype it reps. no cap.

🦋 TYPE_ALNUM

this one holds alphanumeric data. letters AND numbers, she's versatile. main character energy fr.

🌸 TYPE_ALPHA

this one holds alphabetic data. letters only bestie, no digits allowed at this party.

🌈 TYPE_ENUM

this one holds an enumerated type. pick from the list, periodt.

👑 TYPE_INTEGER

this one holds a decimal integer. whole numbers, zero drama.

🧚 TYPE_IPV4

this one holds an IPv4 internet address, e.g., "127.0.0.1". yes the localhost queen herself.

🍓 TYPE_NUMERIC

this one holds a decimal number, with optional sign and decimal point. so like, she can be negative, she can have decimals, she contains multitudes 💖

⭐ TYPE_REGEXP

this one holds a regular expression. regex girlies rise 🙈

💀 PORTABILITY 💀

heads up bestie — the TYPE_IPV4 variable is an extension not provided by older implementations of the form library. so if you're on some ancient setup, don't come for her, she simply wasn't there yet 😭
