247 | There are some issues with readline that can be problematic in event-based |
|
|
248 | programs: |

|
252 | =item blocking I/O |
|
|
253 | |
|
|
254 | Readline uses blocking terminal I/O. Under most circumstances, this does |
|
|
255 | not cause big delays, but ttys have the potential to block programs |
|
|
256 | indefinitely (e.g. on XOFF). |
|
|
257 | |
|
|
258 | =item unexpected disk I/O |
|
|
259 | |
|
|
260 | By default, readline does filename completion on TAB, and reads its |
|
|
261 | config files. |
|
|
262 | |
|
|
263 | =item tty settings |
|
|
264 | |
|
|
265 | After readline has been initialised, it will mangle the termios tty |
|
|
266 | settings. This does not normally affect output very much, but should be |
|
|
267 | taken into consideration. |
|
|
268 | |
|
|
269 | =item output intermixing |
|
|
270 | |
|
|
271 | Your program might wish to print messages (for example, log messages) to |
|
|
272 | STDOUT or STDERR. This will usually cause confusion, unless readline is |
|
|
273 | hidden with the hide method. |

|
277 | Oh, and the above list is probably not complete. |
