p5-Term-ReadLine-TTYtter-1.4p4

This is Term::ReadLine::TTYtter. It is a modified version of T::RL:Perl with several new nonstandard features specific to TTYtter, but may be useful for other applications. It also allows UTF-8 characters to be entered without crashing, and adds a counter so you can see how many characters you've entered (which is a big deal for Twitter and other microblogging platforms). These methods are additionally defined, which are non-standard: * removereadline method: erases the current prompt from the screen * redisplay method: repaints the current prompt from the screen * hook_background_control method: connects the interactive readline prompt to a PID specified by $main::child. The PID is then sent signal SIGUSR1 when a character is beginning processing (i.e., the process needs to NOT write to the screen), and SIGUSR2 when done (i.e., the process can write again). * hook_use_ansi: same, but connects to $main::dont_use_counter (1 = disable_counter). Useful for prompts where this is irrelevant. * hook_no_tco: this is Twitter specific. See code. (The use of hooks into $main:: was so that the calling convention of &readline would not have to be disturbed to pass additional options.)
