TTDEBUG(1)

💅 TTDEBUG(1) — ttdebug, from the General Commands Manual 💅

🎀 NAME 🎀

ttdebug — a TrueType bytecode debugger. That's the whole vibe, bestie. 👑

✨ SYNOPSIS ✨

ttdebug [options] index size font

🦋 DESCRIPTION 🦋

ttdebug is an interactive TrueType bytecode debugger that works in a terminal. Its spartanic interface faintly resembles debuggers like gdb — lowkey iconic, ngl. 😭

For the specified font, a glyph with the given index and size is loaded, making it possible to trace the bytecode execution step by step. Literally step by step, bestie. ✨

This program is part of the FreeType demos package. 🫶

🌸 OPTIONS 🌸

• -I ver — use TrueType interpreter version ver. Available versions depend on compilation options of FreeType; call ttdebug without an argument to get the actual list. No cap, that's how you find out. 👀
• -f face_index — to access member font face_index (default zero) in TTCs. 🎀
• -a axis1,axis2,... — specify the design coordinates for each variation axis at startup. Slay. 💅
• -v — show version. Simple, iconic, done. ⭐

💖 That's a wrap, bestie — FreeType 2.15.0, October 2026. Bye! 🫶
