Next time you have to send a patch, could you please: - use 'git send-email': that will properly format the patch for sending via email, especially, it does not attach the patch, but in-lines it in the body of the mail, which makes it easier to review - when you send a second (or third...) version of a patch, append a 'v2' (or v3, and so on...) to the subject, like: [PATCH v2] Bla blabla... > From 490668696c253bef74e8acd2ff943f20cc4da26b Mon Sep 17 00:00:00 2001 > From: Dirk Gouders <dirk@gouders.net> > Date: Wed, 8 May 2013 14:28:30 +0200 > Subject: [PATCH] mconf: let print_autowrap() handle newline characters. > > When exiting menuconfig with unsaved changes, a dialog like the following is > shown > > Do you wish to save your new configuration ? <ESC><ESC> > to continue. Did you try to replace all the spaces there with newlines, and see what happens? Hint: it's ugly, but not because of the newlines: the window is not resized accordingly to the new number of lines, so better fix that before, too. > The author of the dialog text specified a newline and probably > expected it to be processed, so let print_autowrap() handle newlines propperly. Also, please add your SoB (Signed-off-by) line: http://elinux.org/Developer_Certificate_Of_Origin Otherwise, looks good. I'll do a more thorough review (and testing) later (hopefully when you have fixed that window height issue). Thank you! Regards, Yann E. MORIN.

Yes, I noticed that when I put just two newlines into that text. In general it happens for any text (also without newlines) that does not fit the window height. I solved the problem by adjusting the third parameter in the call to dialog_yesno() and thought that that is the correct way to handle the window-height-problem if the text does not fit, because print_autowrap() currently does not care at all if the given text breaks the window. But I agree, I would be nice if print_autowrap() could handle such cases and I will see if I find a way to do that. I am unsure if that should go into one single patch/commit, though. >> The author of the dialog text specified a newline and probably >> expected it to be processed, so let print_autowrap() handle newlines propperly. > > Also, please add your SoB (Signed-off-by) line: > http://elinux.org/Developer_Certificate_Of_Origin > > Otherwise, looks good.

You are right: it is a non-issue so far; all rendered text currently fit in their respective windows. If those texts get updated, it will be the responsibility to the author to adjust the windows height. Note: the english texts do fit, but I did not check that all translations do. But are there anyone really using the localised texts at all? I'll get your patch as-is in my tree. Depending on Michal, maybe we can queue it in for 3.10. Not too sure, though: the merge window is on the verge of closing, and I'd prefer changes linger for a while in Michal' then next's trees before getting mainlined. > But I agree, I would be nice if print_autowrap() could handle such cases > and I will see if I find a way to do that. I am unsure if that should > go into one single patch/commit, though. Not needed for now, but if you want to work on this, then please do one patch for each semantically self-contained change. Adjusting the height of the window is not tied to rendering the '\n'. Regards, Yann E. MORIN.
