Tests

Some expressions to test (none of them should raise exceptions nor syntax errors ; if not preceded with "?.", all the properties are non-null):

• a?.b.c =>
  • if a == null: a
  • otherwise: a.b.c
• a?.b.c?.d.e =>
  • if a == null: a
  • otherwise if a.b.c == null: a.b.c
  • otherwise a.b.c.d.e
• a?.b.c["key"].d =>
  • if a == null: a
  • otherwise if a.b.c["key"].d
• a?.b.c[k.e.y].d =>
  • if a == null: a
  • otheriwse: a.b.c[k.e.y].d
• a.b.c[k.e.y]?.d =>
  • if a.b.c[k.e.y] == null: a.b.c[k.e.y] == null
  • otheriwse: a.b.c[k.e.y].d
• a.b?.c(a, r, g).d =>
  • if a.b == null: a.b
  • otherwise: a.b.c(a, r, g).d
• if (a?.b.c) { print(Condition Fulfilled, evaluate: ${a.b.c.d.?e}); } else { print("Condition Rejected"); }
  • if a == null: "Condition Rejected"
  • if a.b.c == null: "Condition Rejected"
  • if a.b.c.d == null: "Condition Fulfilled, evaluate: null"
  • otherwise: "Condition Fulfilled, evaluate: "
• (function test(arg) { print(arg); })(a?.b.c)
  • if a == null: print a
  • otherwise: print a.b.c
• tests with switch-case

These expressions should raise syntax error:

• a?.
• a.b?.("ko")
• a.?b["ko"]

These expressions should raise exceptions:

• a?.b.c
  • (a != null and b == null)
