SPVM::D...riables(3)

📦 version 0.990125, in alpine 3.24

🎀 Name 🎀

okay so the header on this one is SPVM::D...riables(3) and the manual name is User Contributed Perl Documentation — but the actual page name is SPVM::Document::EnvironmentVariables - Environment Variables. It's giving environment variable lore, bestie 💅✨

✨ Description ✨

This document explains environment variables. That's the whole assignment, no cap. 🫶

🌸 Environment Variables 🌸

⚠️ first vibe check: if an environment variable is an empty string, it is treated as an undefined value. Periodt.

🦋 SPVM_BUILD_DIR 🦋

SPVM_BUILD_DIR is a directory for files generated by the compiler and linker.

C source codes for precompilation, dynamic link libraries and object files are stored into this directory.

These files are output when attempting to build a module containing methods with the native attribute or the precompile attribute.

🚨 if these files are output and the directory given by SPVM_BUILD_DIR environment variable does not exist, an exception is thrown. Like, exception city. Not a vibe.

Examples:

# bash
export SPVM_BUILD_DIR=~/.spvm_build

# csh
setenv SPVM_BUILD_DIR ~/.spvm_build

💅 SPVM_CC_DEBUG 💅

If SPVM_CC_DEBUG environment variable is a true value of Perl, debug messages and messages from SPVM native class compiler and linker are printed to stderr. Yep, everything goes straight to stderr, iykyk.

🎀 SPVM_CC_QUIET 🎀

If SPVM_CC_QUIET environment variable is a true value of Perl, messages from the SPVM native class compiler and linker are not printed to stderr.

If it is defined and a false value of Perl, the messages are printed.

👑 this setting has a higher priority than SPVM::Builder::Config#quiet field. Iconic priority behavior, honestly.

🔥 SPVM_CC_FORCE 🔥

If SPVM_CC_FORCE environment variable is a true value of Perl, the compilation and link by SPVM native class compiler and linker are forced.

💀 this setting has a higher priority than SPVM::Builder::Config#force field. Forced. Feral. We love to see it.
