* Add go code generator for coremodels * Just generate the entire coremodel for now Maybe we'll need more flexibility as more coremodels are added, but for now this is fine. * Add note on type comment about stability, grodkit * Remove local replace directive for thema * Generate typescript from coremodel * Update pkg/coremodel/dashboard/addenda.go Co-authored-by: Ryan McKinley <ryantxu@gmail.com> * Update cuetsy to new release * Update thema to latest * Fix enum generation for FieldColorModeId * Put main generated object at the end of the file * Tweaks to generated Go output * Retweak back to var * Add generated coremodel test * Remove local replace statement again * Add Make target and call into cuetsy cmd from gen * Rename and comment linsrc for readability * Move key codegen bits into reusable package * Move body of cuetsifier into codegen pkg Also genericize the diffing output into reusable WriteDiffer. * Refactor coremodel generator to use WriteDiffer * Add gen-cue step to CI * Whip all the codegen automation into shape * Add simplistic coremodel canonicality controls * Remove erroneously committed test * Bump thema version * Remove dead code * Improve wording of non-canonicality comment Co-authored-by: Ryan McKinley <ryantxu@gmail.com>
