-V message goes insane in most terminals

[fosskers]

I wonder which ones? My method for animating pacman is pretty reliant on manually moving the cursor around. If the terminal is ignoring that I don't really know what else to do.

[Kwpolska]

most. mate-terminal gnome-terminal terminal/Xfce konsole xterm sakura roxterm, and I haven’t tested everything.

[fosskers]

Wow, thanks for testing this. I had a hell of a day at work yesterday and had no time to look at anything.
So, what is it about urxvt that makes this work? Also, quick question. What happens when you aura -Cb in those terminals? It's update message thingy works on the same principle. (using /r and /b to move back up a line)

[Kwpolska]

[kwpolska@kwpolska-lin ~]% sudo aura -Cb ./bkp
aura >>= Backing up cache to `./bkp`
aura >>= Package files to backup: `47`
aura >>= Proceed with backup? [y/n] y
aura >>= Backing up. This may take a few minutes...

aura >>= Copying #[1]
aura >>= Copying #[2]
aura >>= Copying #[3]
...

On a side note, for stuff like that, early versions of Trashman (those done in the old kru repo) used \b (0x08) for stuff like that and it worked.

[fosskers]

That copy dialog is supposed to stay on the same line! Hmm... so why isn't it?

[Kwpolska]

FOR FUTURE REFERENCE, GIST.

Haskell problem. You are using a fancy raiseCursorBy function. So, I guess this is \r. I decided to do some testing.

#!/usr/bin/python3
print('Hello world #0', end='')

for i in range(1, 50):
    print(len(str(i-1)) * '\b' + str(i), end='')

print()
###
print('Hello world #0', end='')

for i in range(50, 100):
    print('\rHello world #' + str(i), end='')


print()

Output is, in all the terminals mentioned in this thread + guake:

Hello world #49
Hello world #99

It is important that end='' is used for the print() commands. This is important, as without that (i.e. if a newlne is added below), the output is:

Hello world #0
1
[...]
49

Hello world #0
Hello world #50
[...]
Hello world #99

(note the extra newline at the end)

BUT! I ran the code without end='' in urxvt. And:

So, there are some newlines you need to kill in -V and -Cb. Problem solved.

[fosskers]

Thank you.

[Kwpolska]

No problem, I was just bored.

[fosskers]

I was poking at this yesterday. It's hard to void newline characters, since the images I'm animating are multiple lines long.

[fosskers]

Latest commit should have fixed this. By the way, how do you reference commits to issues?

[Kwpolska]

Will test in a minute.

Kwpolska/pkgbuilder#16:

There's one or two lines over in aura to change as well if you could.

It should be right, and if it isn’t, I will provide a pull request in a while.

BTW: if you have a spare moment, I have four strings to translate in PB. Just send them here, in the exact order.

"Running PKGBUILDer as root can break your system!"
"Interrupt signal received\n"
"Synchronizing package databases..."
"Starting full system upgrade..."

[fosskers]

Thanks! And here:

管理者としてPKGBUILDerを実行すると危険性あり！
(actually, could you give me some context for the second line?)
パッケージデーターベースを同期中・・・
完全アップグレードを開始・・・

[Kwpolska]

The second line = ^C message, copied verbatim from Pacman. (#3 and #4 are also straight from pacman)

[fosskers]

Yeah, they looked familiar.
Here's the line:

途中切断

[Kwpolska]

Okay, added in. Releasing when it’s done (and that will be when I will finish testing because of some nasty changes). Thanks!

AuraLogo.hs:6:8:
    Could not find module `System.Console.ANSI'
    Use -v to see a list of the files searched for.

Dep required: haskell-ansi-terminal (another AUR dep, and I’m wrapping the @ArChPm thing up right now, BTW)

Now, it seems to work. But it still fails when using Konsole, yours truly’s terminal emulator of choice. http://bugs.kde.org would love to see a report.

[fosskers]

No problem!

I've already added haskell-ansi-terminal to the PKGBUILD, so people building it officially via the AUR won't have this problem.

As for Konsole.... :( I tried it in sakura and xterm and it worked there so I figured it was problem solved.

As I said, report a bug to the KDE team. That should be enough.
