error handling with throw / command_not_found_handle #107

Closed rogard closed 6 months ago

rogard commented 6 months ago

Under the section in the title one reads:

"You may also force an error by throwing your own Exception:" e="The hard disk is not connected properly!" throw

Is there really supposed to be no ; between the two instructions? Executing it outputs several blank lines whereas I expected a "call stack". I don't know how to interpret the trace from set -x.

Please provide some troubleshooting guidance.

rogard commented 6 months ago

The export command below is necessary in my setup in order to get the call stack to produces visible output. However, the predicate UI.Color.IsAvailable seems too strong, because the terminal does allow for colorized fonts by default. Further, it's unfortunate that the fallback mechanism outputs blank lines.

Colors.sh

alias UI.Color.IsAvailable='[ $(tput colors 2>/dev/null || echo 0) -ge 16 ] && [ -t 1 ]'
if UI.Color.IsAvailable
then
  alias UI.Color.Default="echo \$'\033[0m'"

# truncated code

else
  alias UI.Color.Default="echo"

# truncated code

fi

Terminal:

$ source tangled.sh
$ alias UI.Color.IsAvailable
alias UI.Color.IsAvailable='[ $(tput colors 2>/dev/null || echo 0) -ge 16 ] && [ -t 1 ]'
$ UI.Color.IsAvailable && echo 'true' || echo 'false' 
false
$ tput colors            
tput: No value for $TERM and no -T specified
$ echo $TERM
dumb
$ export TERM=xterm-256color
$ source tangled.sh

This solves the problem permanently:

~/.bashrc
