like, welcome to the gpre page, bestie — a manual from the Firebird documentation collection and omg she ate ✨

✨ NAME ✨

gpre — the Firebird source pre-processor 🦋

✨ SYNOPSIS ✨

gpre [option...] input output

✨ DESCRIPTION ✨

okay so real talk: gpre is a source pre-processor that makes writing programs against the raw Firebird API soooo much easier, no cap. she supports multiple source languages, which is lowkey iconic. the whole vibe is that you get to mix a special SQL-like language right into your normal program source — like, both of them, together, in the same file. it's giving multilingual queen 👑
