目标: Handle Symfony Console silent verbosity suppressing exception rendering, VALUE_NEGATABLE tri-state and boolean default resolution, ArgvInput greedy optional token capture, ArrayInput argument key prefix isolation, non-interactive Question normalizer skipping, and ChoiceQuestion associative key returns HOW
包: symfony/console 8.1.4
环境: php
创建时间: 2026-08-16T08:54:46Z

Running a failing command with --silent (VERBOSITY_SILENT) exits with code 1 but completely suppresses exception rendering, while --quiet (VERBOSITY_QUIET) renders the exception message to error output
Under --silent verbosity, isSilent() is true, isQuiet() is false, and input interactive mode is forced to false
InputOption::VALUE_NEGATABLE defaults to null (tri-state unset) when omitted rather than false, sets true on --flag and false on --no-flag, and accepts boolean defaults in 8.1 while throwing LogicException on non-boolean defaults
ArgvInput greedily consumes the next token as the value for VALUE_OPTIONAL options without an equals sign, leaving subsequent required positional arguments unfulfilled
ArrayInput requires '--' prefix for option keys; passing an unprefixed key sets a matching InputArgument instead and leaves the option at its default value
In ArrayInput, the '--' delimiter key immediately terminates parsing of all subsequent arguments and options
QuestionHelper::ask() in non-interactive mode executes question validators but silently skips normalizers on the default answer
ChoiceQuestion with an associative choice map returns the matching key string rather than the choice label, even when selected by label
