Allow to add commandline option, specially -audit

[opensource21]

On commandline I can set -audit to get audit-log files. It seems impossible for syncthing-macos.
Since the ui only works with embedded syncthing, I don't see any workaroung.

Hi @opensource21, this is currently not possible to inject custom command-line parameters. What you could do is run syncthing from the terminal application on the commandline directly /Applications/Syncthing.app/Contents/Resources/syncthing/syncthing.

First you need to stop it from the tray icon menu:

Thanks for the hint. I choose the following workaround.
In folder
cd /Applications/Syncthing.app/Contents/Resources/syncthing/
Rename the original file
mv syncthing syncthing.org
Created a file mysyncthing.sh

echo "#!/bin/zsh" > mysyncthing.sh
echo "/Applications/Syncthing.app/Contents/Resources/syncthing/syncthing.org -audit $@" >> mysyncthing.sh
chmod a+x mysyncthing.sh

and create a link
ln mysyncthing.sh syncthing

So I can be sure to always has audit enabled.
The audit-files can be found at ~/Library/Application Support/Syncthing/.

Only drawback: At each update I need to call

mv  /Applications/Syncthing.app/Contents/Resources/syncthing/syncthing 	/Applications/Syncthing.app/Contents/Resources/syncthing/syncthing.org 
ln /Applications/Syncthing.app/Contents/Resources/syncthing/syncthing /Applications/Syncthing.app/Contents/Resources/syncthing/mysyncthing.sh

So I would really appreciate if you can make possibility to a permanent customization.

Dear @opensource21,

As requested I added (preliminary) support for adding "power user" arguments to syncthing. It is currently a hidden feature which is not available from the GUI because I have a not enough experience programming in Swift/Objective C and using XCode Interface Builder.

You can download a v1.16.1-2 release from https://build.syncthing.net/repository/download/SyncthingMacOS_BuildReleaseDmg/101990:id/Syncthing-1.16.1-2.dmg

And you should set the arguments from terminal this way:

defaults write com.github.xor-gate.syncthing-macosx Arguments '--audit --auditfile=/Users/jerry/staudtifilefromcfg.log'

See also the above commit.

Please let me know if it works for you. And consider donating my hard work ;-)

[opensource21]

Works like a charm. Perfect solution in my eyes. I think persons who want this feature, will read the Readme.md and will be happy. I had tried to change the executable in defaults, but it can't be changed.

Thanks for your work. For me the issue can be closed.

[xor-gate]

The executable in the defaults is an old/deprecated feature. So yes this is not working (anymore). Have fun!

[xor-gate]

I have released v1.16.1-2 which is the addition of this feature request.

Just adding this note here related to debugging going on over at https://forum.syncthing.net/t/com-apple-provenance/19262/17

For anyone who wants to increase the logfile size using the macOS bundle, you can use:

# sets logfile size to 50MB, and keep the last 5 during logrotate 
defaults write com.github.xor-gate.syncthing-macosx Arguments '--log-max-size=52428800 --log-max-old-files=5'

And when you're done debugging, use this to revert things back to default:

defaults delete com.github.xor-gate.syncthing-macosx Arguments

I believe you need to fully quit the Syncthing app after each of these changes (not just stop/start the service) for it to take effect.

Commenting on your findings:

Yes the Arguments are loaded only on startup. Not when changed.
