CudaText

CudaText is a cross-platform text editor, written in Object Pascal. It is open source project and can be used free of charge, even for business. It starts quite fast: ~0.3 sec with ~30 plugins, on Linux on CPU Intel Core i3 3GHz. It is extensible by Python add-ons: plugins, linters, code tree parsers, external tools. Syntax parser is feature-rich, based on EControl engine (though not as fast as in some competitors).
