GP2C(1)

💖 GP2C — bestie edition 💖

okay so this is a PARI manpage, and the whole thing is literally about GP2C, aka The GP to C compiler. pull up a chair, grab a boba, we're doing this 🧋✨

✨ NAME ✨

GP2C — the GP to C compiler 🫶

🌸 SYNOPSIS 🌸

gp2c [-ghfltvydWSTGV] [-i N] [-o <file>] [-p <prefix>] [file.gp]

💅 DESCRIPTION 💅

gp2c is a program that translates GP code into C code that uses the libpari library. it literally tries to generate code that looks like the PARI source code. main character energy fr 💖

🎀 user option:

• -o <file> — place output in file <file>. yes bestie, your code goes here now 💌
• -g — generate automatic garbage collection code. let the machine clean up after itself, iconic 🧹✨
• -iN — set the indentation level to N spaces (default 2). two spaces is the vibe, but you do you 💅
• -W — output warning about types and global variables usage. she's keeping receipts 📝
• -C — generate range checking code. safety first, always 🛟
• -L — generate #line directive for better C compiler messages. so when the compiler yells, it yells accurately 😭
• -p <prefix> — prefix user-defined symbols by <prefix> to avoid conflict. no fighting in the group chat, periodt 🚫
• -s <suffix> — add suffix <suffix> to GP install names of functions. a lil extra on the end, we love accessories 💅
• -S — assume strict declarations for functions. strict but fair 👑

🦋 query options:

• -h — this help. hi bestie, you're welcome 🫶
• -f — dump information about functions to stderr. spill the tea, but to stderr specifically ☕
• -l — output the list of functions known to the compiler. the full roster, no gatekeeping 🌈
• -t — output the table of types known to the compiler. every type, accounted for ✨
• -v — output version information and exit. quick lil fact check, then she's out the door 👋

🔥 debugging options:

• -d — increase debugging level. turn the drama up 📈
• -y — switch parser to debug mode. the parser is now in its detective era 🕵️‍♀️
• -T — output syntactic tree in treetool format. look at the tree bestie, it's giving arboreal 🌳
• -TT — output syntactic tree in VCG/GRL format. double T, double tree, we love a sequel 🌲🌲
• -G — generate GP code in place of C code. don't smile. 😐 (okay that's what it says, i'm just the messenger 😭)
• -V — do not clean up variables. chaotic, leaving the mess exactly where it is 💀
• file.gp — file to be processed, defaulting to stdin. the generated C code is output to stdout unless option -o is used. so: no file = read from stdin, no -o = write to stdout, simple as 🎀

also!! see the script gp2c-run for an automated compilation process. she does the whole thing for you, no cap 👑
