How to specify (all) Chrome://flags via command line

[JoachimHenze]

OS: WinXP SP3 32 bit
Supermium version: Supermium 122.0.6261.85 Hotfix (R2) 32bit https://github.com/win32ss/supermium/releases/tag/v122-hf

part of the settings I do specify for Supermium as cmdline flags, and part as Chrome://flags
For me the cmdline generally is more user-friendly, as it allows me to save a set of flags for later reusage into a txt file, e.g. for when installing the browser onto a different computer.
Dreaming of specifying all my chrome flags via cmd-line therefore.

By googling I found some sites mentioning various syntax-options, but none of them worked for me:
--disable-sharing-hub did not work
--chrome-labs=false did not work
--chrome-labs=disabled did not work
--chrome-labs=0 did not work
--flag-switches-begin --enable-features=disable-sharing-hub --flag-switches-end did not work
--flag-switches-begin --disable-features=chrome-labs --flag-switches-end did not work

It seems as if the set of legit cmdline flags is different to the chrome://flags .

Is that possible? E.g. How would I have to extend my existing cmdline
C:\Programme\Supermium\chrome.exe --disable-remote-fonts --safebrowsing-disable-download-protection --use-angle=gl --in-process-gpu
if I additionally wanted to set #disable-sharing-hub to "enabled" and #chrome-labs to "disabled" at cmd-line for example?

Is that possible? If not, is there a way to export and reimport the chrome://flags into some file?

For Chrome Labs, it is a FEATURE_WITH_PARAMS_VALUE_TYPE, and it can be disabled using the command line syntax --disable-features=ChromeLabs. The problem is that the string is not referenced on the chrome://flags page, but only in chrome/browser/about_flags.cc as the last parameter in the FEATURE_WITH_PARAMS_VALUE_TYPE macro.

--disable-sharing-hub is a standard single value type flag, and as such is the valid syntax. It works for me.

You are correct. Both works. I must have made a typo when I initially tested --disable-sharing-hub
I do confirm that both do work.
Initially I wanted to ask you for all my other flags too (as the syntax is not super easy for me to understand), but I just realized now that the length of the string one can enter in the Windows shortcut dialog is not endless, but limited, and not long enough for all my flags. So if I really wanted to specify everything via the command line, I would have to use some kind of intermediate batch file. That's rather ugly. Therefore I guess what I had in mind here is not really possible (under Windows at least).

If you want to take at least some kind of idea then from this report as a possible future improvement for Supermium, then it would be a feature to have a button in the chrome://flags page that would allow saving all the flags that are currently set explicitly by the user into some txt-file.
One button to save them, and one to restore them from a file.
But I will resolve this ticket here now nevertheless, no matter whether you will implement that or not. Thank you for your time.
