Bug 65829 – search text not displayed in pinfo emerged with readline support

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Jaroslav Sladek 2004-09-29 09:43:05 UTC]

When pinfo is emerged with USE=+readline set, after user invokes search (either with / or s key), prompt is displayed, but typed text is invisible, and bottom status line ends up being garbled. Little research reveals that pinfo uses readline function to read search string from user, which doesn't really play well with ncurses. Without readline in USE flags, it uses its own implementation of search, which works fine for me (except small troubles with backspace in Konsole).

All major distributions I was able to check (Fedora, Mandrake) seem to contain pinfo which is not linked against readline, so I'd suggest considering if it's not better to disregard +readline flag in this case, since readline functionality doesn't seem to be well tested. Another possibility is using little patch, which envelopes call to readline() with endwin and refresh, to temporary leave curses. This works, but looks somehow wierd.

Reproducible: Always
Steps to Reproduce:
1. USE=+readline emerge pinfo
2. pinfo
3. press s and try writing search term

Actual Results:  
Search term is not visible

Expected Results:  
Search term should normally display

Created attachment 40713 [details, diff]
Patch that leaves curses before search term is entered.

Patch against current pinfo-0.6.8 version of pinfo. It leaves curses before
calling readline and restores them back again after it. However, being dumped
on text screen doesn't seem to be user friendly very much.

Re-assign.

Fixed in new app-text/pinfo-0.6.9 release. Thank you for reporting this!
