| # By A "Clap First" plugin, we mean a plugin which is *just* implmented as | ||
| # CLAP and uses this wrapper to project into the various other platforms. | ||
| # | ||
| # One special form of clap first plugin does that by creating a | ||
| # the platform plugins with the entire clap library built in. While there's | ||
| # a few ways to do this the pattern which eemse to work best is | ||
| # | ||
| # 1. Write the etnire DSP, handling, etc... of your clap as a library without | ||
| # the clap entry | ||
| # 2. Have a minimal clap entry c++ file which just exposes the entry points from | ||
| # that static library | ||
| # 3. Make each of the clap, vst3, auv2 etc... link the static library from 1 but | ||
| # recomile the entry from 2, so the resulting plugin has the entry point exposed. | ||
| # | ||
| # We show an example of that here with a slightly modified version of the | ||
| # basic c99 distortion plugin, here re-coded using a C++ compiler. | ||
