feat(examples): improve p/demo/ufmt #2553

grepsuzette · 2024-07-09T07:38:50Z

support for stringer, error
support for %c verb
allow to show value as in Go fmt.Sprintf
allow to show verb/type mismatches as in Go fmt.Sprintf
add some tests

@moul

- add p/demo/tictactoe (basically @moul's model gnolang#613) - add p/demo/tictactoe1p (human VS cpu logic, extending the above) - add p/demo/ternary (to cope w/ not having C `a ? b : c` ternary operator) - add r/demo/games (start addressing gnolang#611) - add r/demo/games/tictactoe This last realm is a playable demo against a parrot which, somehow learned how to play Tic-tac-toe. This is a stateless realm which uses gnoweb as a webserver and uses css to offer a game-like experience without javascript. this depends on gnolang#2553 (improved ufmt)

* support for stringer, error * support for %c verb * allow to show <nil> value as in Go fmt.Sprintf * allow to show verb/type mismatches as in Go fmt.Sprintf * add tests

This line // {"error: %s", []interface{}{errorToBePrinted}, "error: can I be printed?"}, gave panic: reflect: reflect.Value.SetString using value obtained using unexported field Seems to have to do with the for loop using []interface{} and what was being done in the body of the for. in gnovm/stdlibs/error, exporting s in errorString fixed the error: type errorString struct { S /* <- this */ string } But moved the test in its own function, this passes: ``` func TestPrintErrors(t *testing.T) { got := Sprintf("error: %s", errors.New("can I be printed?")) expectedOutput := "error: can I be printed?" if got != expectedOutput { t.Errorf("got %q, want %q.", got, expectedOutput) } } ```
