Examples with VarDec ast.Ast.VarDec used on opensource projects

Example 1 with VarDec

use of ast.Ast.VarDec in project L42 by ElvisResearchGroup.

the class Desugar method visit1Step.

public MCall visit1Step(SquareCall s) {
    //we can assumethe receivers are normalized after DesugarContext
    //assert s.getReceiver() instanceof Ast.Atom:      s.getReceiver();
    //but nor really, since vars accesses are replaced by meth calls. In that case is fine to not have an atom.
    //(b=r.builder() b.a() b.b() b.c() .... b)
    List<VarDec> vd = new ArrayList<>();
    Expression k = getMCall(s.getP(), s.getReceiver(), "#seqBuilder", getPs());
    String x = Functions.freshName("b", usedVars);
    X b = new X(s.getP(), x);
    vd.add(new VarDecXE(false, Optional.empty(), x, k));
    for (Parameters ps : s.getPss()) {
        vd.add(new VarDecE(getMCall(s.getP(), b, "#add", ps)));
    }
    Expression inner = getBlock(s.getP(), vd, b);
    Parameters ps = new Parameters(Optional.empty(), Collections.singletonList("seqBuilder"), Collections.singletonList(inner));
    return getMCall(s.getP(), s.getReceiver(), "#from", ps);
}
