Watch Variables can't be resolved after a Debugging Restart and Debugger does not start

[daniel-brosche]

Hallo,

I have noticed that when I add a Variable to the Watch Window the Debugger is not able to resolve this Variable when I restart the Debugger and the Debugging will not be started.

My concrete use case:
1.) Start Debugger
2.) Add Variable to Watch Window -> no problem, variable value will be resolved
3.) continue debugging (some steps)
4.) restart the debugger -> debugger can't resolve variable and does not start debugging

In the Watch window appears the following error message:

TypeError: Cannot read property 'stdin' of undefined

I was able to reproduce this.

Please try following package to check the fix:
bash-debug-0.0.5.vsix.zip

code --install-extension bash-debug-0.0.5.vsix

Hello,

the Bug is bassically gone.
I can now restart the Debugging without any issues.
During my checks I have noticed another problem.
I have added a Variable to the Watch Window which is called DebPath.
The Watch Windows shows the following value:

DebPath = 'declare -- DebPath="/sdcard/20160316_armhf.deb"'

Probably there is a issue in the parsing of the value. For my understanding it should look like:

/sdcard/20160316_armhf.deb

When the value is not defined resp. assigned it looks like:

DebPath = 'DebPath'

It think it would be event better and more consistent when the value is not defined / assigned to show just:

not available

This corresponds to the same value when the Debugging has been stopped.

Best regards, Daniel...

I am connecting watch and peek features of debug adapter to "examine" command of bashdb. It will return those "declare .." words if watch is "DebPath", not "$DebPath". However, I noticed that the expression name "DebPath" is redundant in response, so I will remove it so that only value is shown in single quotes.

I will need to properly document how watch works, since i do not want to make any workarounds related to the problem at this point...

Is this fix already public available in Form of a Release?

[rogalmic]

v0.0.7 should contain all the fixes I could do for now. It is published to VS Code marketplace...
