form_variables(3X)

💅 form_variables(3X) — Library calls, bestie ✨

Okay so real talk, this is one of those pages from the ncurses form library crew, and the manual name on the tin is literally form_variables. It's short, it's sweet, it's giving "reference card energy" — let's go 🎀

---

✨ NAME ✨

TYPE_ALNUM, TYPE_ALPHA, TYPE_ENUM, TYPE_INTEGER, TYPE_IPV4, TYPE_NUMERIC, TYPE_REGEXP — these are the form system global variables, and yes they're all in caps because they're that iconic 💅

🌸 SYNOPSIS 🌸

#include <form.h>

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

🦋 DESCRIPTION 🦋

So these bad boys right here are the building blocks of the form library ✨ They define fields — like, the actual field types you can create using the form_fieldtype(3X) functions. Each one comes with its own little function squad for field-validation and character-validation, and it all depends on which datatype you're rolling with. No cap 🫶

🍓 TYPE_ALNUM

This one holds alphanumeric data. Letters AND numbers, the whole package 💖

🎀 TYPE_ALPHA

This one holds alphabetic data. Just letters, keep it cute 🌸

⭐ TYPE_ENUM

This one holds an enumerated type. iykyk 👑

🔥 TYPE_INTEGER

This one holds a decimal integer. Whole numbers only, bestie 💜

🌈 TYPE_IPV4

This one holds an IPv4 internet address, e.g., "127.0.0.1". Localhost era 🧚

💫 TYPE_NUMERIC

This one holds a decimal number, with optional sign and decimal point. Flexible queen behavior ✨

🦄 TYPE_REGEXP

This one holds a regular expression. Regex girlies rise 🙈

💀 PORTABILITY 💀

Heads up, bestie: the TYPE_IPV4 variable is an extension — it is not provided by older implementations of the form library 😭 So if you're on some ancient build, don't come for her when she's not there.

👑 SEE ALSO 👑

• form(3X) — go read it, it's the main character 💅
