[DSF Extension] Exec On MCode (was: Shutdown SBC)

wilriker

@gtj0 Glad to hear about any use-cases.

I myself use it to run poweroff as well as activating and deactivating my webcam (starting/stopping a systemd unit).

Tempting to try with a small I2C OLED on the Pi, but not top of the list just yet

This sounds really good. I would like to use it to activate a bash script on my system but I have attempted to install it and I cant get it to work.
I followed your instructions in your first post but using execonmode V3:

I downloaded execonmode and placed it into /usr/local/bin.
I tried to run it using sudo ./execonmode -help (just to see if it works) but I get the error message "cant open binary".

Could you instruct me where i'm going wrong.

BTW I am on the latest version of RRF3 and up to date with DSF etc.

Thanks in advance.

@chas2706 If you run

sudo ./execonmcode -help

It will try to find the executable in the current directory you issue this command. To have your shell locate it in your $PATH remove the ./ in front of execonmcode. For -help you don't need sudo BTW.

To make sure that it can find it also check if

echo $PATH

actually does contain /use/local/bin.

Last thing: you spelled it execonmode instead of execonmcode (extra "c" after "m") above. Make sure that's only a typo here. I might rename the executable in the future to something less error-prone.

@wilriker
Thanks for the info. I will give it another go.

execonmode was just a typo error in my post lol.

Thanks

./execonmcode -help

I have placed execonmcode in /usr/local/bin and typed the following in the terminal without success:

pi@Duet3:~ $ cd /usr/local/bin
pi@Duet3:/usr/local/bin $ ls
execonmcode listen-for-shutdown.py
pi@Duet3:/usr/local/bin $ ./execonmcode -help
bash: ./execonmcode: Permission denied
pi@Duet3:/usr/local/bin $ sudo ./execonmcode -help
sudo: ./execonmcode: command not found
pi@Duet3:/usr/local/bin $ execonmcode -help
bash: /usr/local/bin/execonmcode: Permission denied
pi@Duet3:/usr/local/bin $ sudo execonmcode -help
sudo: execonmcode: command not found
pi@Duet3:/usr/local/bin $

@chas2706 Have you made execonmcode executable via sudo chmod +x /usr/local/bin/execonmcode? I think that's missing from the installation instructions.

chas2706

@wilriker

No I forgot!!

My silly mistake! It works a treat now.

Thank you for your help.

wilriker

@chas2706 Thank you for implicitly pointing out a hole in the installation instructions. I amended that to GitHub already and will fix it above in an instant.

chas2706

@wilriker

No problem, again thanks for your help and for producing a fantastic plugin.

Important Note

The current version of Exec On MCode is NOT compatible with DSF 1.3.0+. It will connect but fail at a random point in time which might lead to breaking side-effects. I will release a new version tomorrow or Monday. Until then, don't use this tool with DSF 1.3.0+.

Important Note

I plan to temporarily remove this feature can you confirm that all I need to do this is to delete the extension?
I did not enable it to run at start up.
Many thanks for pointing this out.

wilriker

@chas2706 If you don't start it (automatically or manually) there is no need to do anything. It can sit in the filesystem that won't have any effect until you execute it.

Release 4.0

This version works with DuetSoftwareFramework 1.3.0 and later.

Unfortunately due to breaking changes in the API of DSF this is NOT backwards-compatible with older versions of DuetSoftwareFramework.

This release also has a new parameter -trace that will enable output of the underlying requests/responses to/from DuetControlServer.

It can be downloaded as usual from GitHub Releases page.

wilriker

Release v5.0

This release updates godsfapi to v2 and thus is only compatible with Duet Software Framework 2.1.0 and later.

New Features

A new command-line paramter -version to output the version and exit

Bug fixes

After a handled code is intercepted and before the assigned command is executed Flush will be called to make sure we are in sync with the machine

It can be downloaded as usual from GitHub Releases page

So many possibilities, so little time. I'd like to take a week off from my day job to do all the things that things like this can enable.

wilriker

Release 5.1

This release makes execonmcode compatible with Duet Software Framework 2.2.0 and later.

It can be found at GitHub Releases page as usual.

 dial unix /var/run/dsf/dcs.sock: connect: no such file or directory

Sorted it out! The PI has to be connected to the Duet!
