% This file is written in Prolog
% It contains rules that the project must respect.
% In order to see them in action, run `berry constraints detail`

% This rule will prevent two of our workspaces from depending on different versions of a same dependency
gen_invalid_dependency(WorkspaceCwd, DependencyIdent, 'This dependency conflicts with another one from another workspace') :-
  workspace_has_dependency(WorkspaceCwd, DependencyIdent, DependencyRange),
  workspace_has_dependency(_, DependencyIdent, DependencyRange2),
  DependencyRange \= DependencyRange2,
  \+(gen_enforced_dependency_range(WorkspaceCwd, DependencyIdent, _)).

% This rule will prevent workspaces from depending on non-workspace versions of available workspaces
gen_enforced_dependency_range(WorkspaceCwd, DependencyIdent, 'workspace:*') :-
  workspace_ident(_, DependencyIdent),
  workspace_has_dependency(WorkspaceCwd, DependencyIdent, _).

% The following rules describes which workspaces are allowed to depend on respectively "webpack" and "typescript"
workspace_allowed_dependency(WorkspaceCwd, 'webpack') :-
  workspace_ident(WorkspaceCwd, '@berry/builder').
workspace_allowed_dependency(WorkspaceCwd, 'typescript'):-
  workspace_ident(WorkspaceCwd, '@berry/builder').

% This rule will prevent workspaces from depending any blacklisted package
gen_enforced_dependency_range(WorkspaceCwd, DependencyIdent, null) :-
  workspace_has_dependency(WorkspaceCwd, DependencyIdent, _),
  workspace_allowed_dependency(_, DependencyIdent),
  \+(workspace_allowed_dependency(WorkspaceIdent, DependencyIdent)).

% This rule will prevent all workspaces from depending on tslib
gen_enforced_dependency_range(WorkspaceCwd, 'tslib', null) :-
  workspace_has_dependency(WorkspaceCwd, 'tslib', _).
