✨ AST(3) ✨

okay bestie, welcome to the c-like expression library — it's giving expr, it's giving Library Functions Manual, and it is lowkey iconic. sit down, grab a strawberry 🍓, and let's get into it.

💖 NAME 💖

expr — the c-like expression library. that's it, that's the whole name. short, sweet, slays. 💅

🦋 SYNOPSIS 🦋

first things first, you gotta let it in:

#include <graphviz/expr.h>

then here's the whole squad of functions, fr fr:

Expr_t*          exopen(Exdisc_t*);
Excc_t*          exccopen(Expr_t*, Exccdisc_t*);
int              exccclose(Excc_t*);
void             exclose(Expr_t*, int);
char*            excontext(Expr_t*, char*, int);
void             exerror(const char*, ...);
Extype_t         exeval(Expr_t*, Exnode_t*, void*);
Exnode_t*        exexpr(Expr_t*, const char*, Exid_t*, int);

and the second half of the girlies, the node/token/compile crew:

Exnode_t*        excast(Expr_t*, Exnode_t*, int, Exnode_t*, int);
Exnode_t*        exnewnode(Expr_t*, int, int, int, Exnode_t*, Exnode_t*);
void             exfreenode(Expr_t*, Exnode_t*);
int              expush(Expr_t*, const char*, int, const char*, FILE*);
int              expop(Expr_t*);
int              excomp(Expr_t*, const char*, int, const char*, FILE*);
int              extoken(Expr_t*);
char*            extype(long int);
Extype_t         exzero(long int);

no cap, that's all of them, copy them exactly bestie, character for character, we do not freestyle signatures in this house. 🙈

🌸 DESCRIPTION 🌸

okay so here's the tea, and it's actually a short one so pay attention:

• exopen() — this is the first function called. the opening act. the main character entrance. nothing happens before her. 👑
• exclose() — and this is the last function called. the closing credits. she locks up when everyone's done. 🎀
• exccopen() — she's the one you call if code generation will be used. conditional queen. only shows up when the codegen vibe check is passed. ✨
• exccclose() — she releases the state information allocated in exccopen(). so like, whatever exccopen() set up, exccclose() takes it back down. they're a matched set, don't separate them. 🫶

that's literally the whole description section, bestie. the manpage said what it said and we're not adding a single technical claim that isn't there. periodt. 💀

🌈 SEE ALSO 🌈

literally just itself. the self-referential icon behaviour. AST(3), no notes. 🪞

and that's a wrap on the AST(3) manual page, from the Library Functions Manual — written up all cute for you with zero details left behind, every flag, signature, and function accounted for. mwah. 💋✨
