spdlog level alignment question

[wanzzhehe]

Hello everyone, is there any simple way to align level just like this?

[2018-11-01] [info]     INFO MESSAGE
[2018-11-01] [error]    ERROR MESSAGE
[2018-11-01] [critical] CTRITICAL MESSAGE

Or I should write a custom formatter to achieve this goal?

Yes, the Align flag only affects format patterns, so alignments are generated in square brackets that appear before or after the format pattern.
Please create a custom formatter with reference to level_formatter:

spdlog/include/spdlog/pattern_formatter-inl.h

Lines 115 to 127 in b18a234

	// log level appender
	template <typename ScopedPadder>
	class level_formatter final : public flag_formatter {
	public:
	explicit level_formatter(padding_info padinfo)
	: flag_formatter(padinfo) {}
	void format(const details::log_msg &msg, const std::tm &, memory_buf_t &dest) override {
	const string_view_t &level_name = level::to_string_view(msg.level);
	ScopedPadder p(level_name.size(), padinfo_, dest);
	fmt_helper::append_string_view(level_name, dest);
	}
	};

Thanks a lot for your answer.

I think you can simply use the align flags without any custom code.

Thanks for your answer. However, the align flags can't achieve my goal.
