Description
Right now to support nested table we must either reimplement it or reuse TableInterceptor with some plumbing:
@Command
@ApplicationScoped
public class Commands {
@Inject
private JiraService jira;
@Table(border = asciiSeparated)
@Command(value = "list-projects")
public List<FormattedProject> listProjects(@Option("jira-login") final JiraService.JiraLogin login,
@Option("jira-client") final JiraService.JiraClient configuration) {
final var formatter = new TableInterceptor();
return jira.findProjectsWithTasks(login, configuration).stream()
.map(p -> new FormattedProject(p.id(), p.label(), asTable(formatter, p.tasks())))
.collect(toList());
}
@Table(border = asciiSeparated)
private String asTable(final TableInterceptor formatter, final List<JiraService.Task> tasks) {
final var formatted = formatter.intercept(new CrestContext() {
@Override
public Object proceed() {
return tasks;
}
@Override
public Method getMethod() {
try {
return Commands.class.getDeclaredMethod("asTable", TableInterceptor.class, List.class);
} catch (final NoSuchMethodException e) {
throw new IllegalStateException(e);
}
}
@Override
public List<Object> getParameters() {
return List.of();
}
@Override
public String getName() {
return "formatAsTable";
}
@Override
public List<ParameterMetadata> getParameterMetadata() {
return List.of();
}
});
if (formatted instanceof PrintOutput po) {
final var out = new ByteArrayOutputStream();
try (final var ps = new PrintStream(out)) {
po.write(ps);
} catch (final IOException e) {
throw new IllegalStateException(e);
}
return out.toString(UTF_8);
}
throw new IllegalStateException("Unknown type: " + formatted);
}
public record FormattedProject(String id, String label, String tasks) {
}
}
This works but I would expect asTable to be replacable by @Table on the nested type (public record Project(String id, String label, @Table(...config...) List<Task> tasks) { }) which would make it simpler but would also avoid to depend on the implementation module in commands.
Tip if you need the same feature: you can move this code in an utility class and call it to preformat your data before the rendering:
@Table(border = asciiSeparated)
@Command(value = "list-projects")
public List<FormattedProject> listProjects(....) {
return jira.findProjects(login, configuration).stream()
.map(p -> new FormattedProject(p.id(), p.label(), AsTable.asTable(p.tasks()))) // here is the trick, AsTable is previous code in a static utility class
.collect(toList());
}
