blanks are printed instead of stack trace in simple example
My first attempt to use this project failed.
#!/bin/bash
source "$( cd "${BASH_SOURCE[0]%/*}" && pwd )/lib/oo-bootstrap.sh"
import util/exception
ta() {
touch /untouchable
}
ta
running it:
$ /t/bash-oo-framework/x.sh
touch: cannot touch '/untouchable': Permission denied
! Press [CTRL+C] to exit or [Return] to continue execution.
I'm on bash 4.3.48(1)-release, and for this project, 903fd74533631c9e46a7554833f494838f645731
Hi @ian-kelling ,
The same script works for me:
# cat 1.sh
#!/bin/bash
source "$( cd "${BASH_SOURCE[0]%/*}" && pwd )/lib/oo-bootstrap.sh"
import util/exception
ta() {
touch /tmp/a/untouchable
}
ta
Output:
# ./1.sh
touch: cannot touch â/tmp/a/untouchableâ: No such file or directory
â UNCAUGHT EXCEPTION: /tmp/a/untouchable (1)
î ⦠touch /tmp/a/untouchable [1.sh:7]
î ⦠ta [1.sh:9]
â¡ Press [CTRL+C] to exit or [Return] to continue execution.
â Continuing...
â UNCAUGHT EXCEPTION: ta (1)
î ⦠[[ $index -lt $backtraceNo ]] [1.sh:170]
î â [1.sh:170]
â¡ Press [CTRL+C] to exit or [Return] to continue execution.
â Continuing...
Run from root bash 4.2.46(2)-release bash-oo-framework from master branch: https://github.com/niieani/bash-oo-framework/tree/master
@ian-kelling I guess something is wrong with the way your terminal prints -- either unicode characters or colors, and we don't manage to catch that it's a non-colored terminal.
You could try forcing the unicode off by setting this global variable: NO_UNICODE=1. Let me know if this helps.
What kind of terminal are you using?
I'm runing GNU bash, version 4.3.48(1)-release (x86_64-pc-linux-gnu)
I ran this in konsole, mate-terminal, and xterm all with export NO_UNICODE=1. All had the same result. All terminals print color just fine.
And if I run ./x.sh |& out, i can inspect the file and see that those empty lines are just empty.
That's super odd @ian-kelling. I'm not able to reproduce it. I'd have to try it in a linux virtual machine, but you've been the only one so far to report this behavior.
I can reproduce this too, my setup is:
- bash-oo-framework: v2.1
- Ubuntu 16.04, Linux kernel 4.4.0-142-generic
- terminals: Terminator 0.98 and xfce4-terminal v0.6.3 (Xfce 4.12)
- Bash version 4.3.48(1)-release
It looks like the problem is only present in non-fancy (non-colorized) output mode.
I checked that tput colors returns 8 on my terminal, so UI.Color.IsAvailable is 0. I also checked that changing $TERM from xterm to xterm-256color (which seems valid for my terminal) restores the correct output - backtrace is now fully visible.
