Not getting past writing colors in save_file

[Aerol]

Seems to be getting stuck at writing colors or something, when i run
wal -i ~/wallpapers/16.9/
never exits and when I hit ^c twice

~
❯ wal -i ~/wallpapers/16.9

During handling of the above exception, another exception occurred:

Running Maui Linux 17.03, Ubuntu 16.04 based.
Odd thing is, it doesn't always happen, but it happens more so than not.

Does it hang when the -n flag is used?

[Aerol]

Yes it does

[dylanaraps]

Can you send me the output of ls /dev/pts?

[Aerol]

❯ ls /dev/pts
0  1  10  11  12  13  14  15  16  17  18  2  3  4  5  6  7  8  9  ptmx

[dylanaraps]

Can you try and install these packages? Then let me know if this changes anything.

apt-get install libatk-adaptor libgail-common

[Aerol]

No change in end result, other than the errors about atk and gail modules are gone.

[dylanaraps]

What about ls -l /dev/pts? This could be a permissions issue.

[Aerol]

❯ ls -l /dev/pts

Doing some testing, I closed down all tmux windows and tmux server, ran wal outside of tmux and it ran fine some 30 times, started tmux and it ran fine continually again....
and now it seems no matter what I try I can't get wal to hang again

I have this issue too with arch linux where the /dev/pts/* files are owned by nobody instead of the current user, and it causes this same problem. Not sure what's changing the owership of my ttys.

[dylanaraps]

I'll add a check to the code so that we only write to the files if they're writable. If they're not writable we can at least display a helpful message on how to fix the issue.

From googling you can just chmod the files to fix them. (chmod a+rw /dev/pts/1)

[dylanaraps]

Closing this.

If you come across the issue again feel free to reopen the issue.

I got the similar issue that pywal hangs when tring to write data to /dev/ptsX, e.g.:

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/bin/wal", line 11, in <module>

I'm on Manjaro cinnamon and my pywal installed from AUR is 0.6.9.
I greped the ps aux output and found a tmux session is still alive, killed it and now pywal runs OK.
