// Search a SpellGrid level (Module 10) for solutions, by brute force, with the course's
|
|
// TypeScript reference engine. Used in Module 11 to check that a level has the solution
|
|
// its designer meant and no other.
|
|
//
|
|
// node tools/solve-spellgrid.mjs [level] [--dir <dir>] [--max N] [--naive] [--never-rule "X IS Y"] [--all]
|
|
// npm run solve:spellgrid -- l1 --never-rule "DEATHRATTLE IS DOUBLE"
|

//
|
|
// Stages the Module 10 TypeScript reference with its cards and levels, as play-spellgrid
|
|
// does, copies tools/solver/solve.ts beside it and runs it there. `level` is a level of
|
|
// course/10-spellgrid/levels by name or prefix (`l1`), or a path to a level file; default `l1`.
|
|
// The other options are the solver's: see tools/solver/solve.ts.
