DIAGTOOL(1)

🌸 NAME 🌸

diagtool — clang diagnostics tool. This is the DIAGTOOL(1) page from the Clang manual, and honestly it’s giving very “I have my diagnostic life together” energy, bestie 💅✨.

✨ SYNOPSIS ✨

diagtool command [args]

💖 DESCRIPTION 💖

okay so diagtool is a combination of four tools for dealing with diagnostics in clang. That’s the whole tea: four little diagnostic besties, all here to help you deal with diagnostics in clang 🫶🔥.

🎀 SUBCOMMANDS 🎀

diagtool is separated into several subcommands, each one tailored to a different purpose. Here’s the quick rundown, with more detail in the sections that follow — iykyk 💫.

• find-diagnostic-id — prints the id of the given diagnostic. 🦋
• list-warnings — lists warnings and their corresponding flags. ✨
• show-enabled — shows which warnings are enabled for a given command line. 🔥
• tree — shows warning flags in a tree view. 🌳
