Hello Again: Still struggling with my xmobar config and workspaces issues. Figured out something I don't quite get why it is not working, but in xmobarrc I am using ", RUN StdinReader" (and have tried the UnsafeStdinReader variation as well) and this causes xmobar not to run at startup again. If I start xmobar from the terminal it runs and does not error. in my xmobar.hs it is called via xproc inside my main do block. I am attaching both files as they appear today. Thank you guys for all the help so far. Please do tell me if I am missing some imports or something I need! Also all the fonts listed are installed and verified as in my fc-cache on the EOS system. -- Kind Regards, *John Michael Needham*

I'm hoping someone else can help you because I don't use and am not familiar with xmobar. You might also be able to get help on Reddit. On Fri, Apr 8, 2022 at 11:56 AM Michael Needham wrote:

Brandon: I appreciate your help so far. I am further along because of your suggestions and advice, so I am appreciative! Perhaps someone does know, Reddit in my experience is not that helpful and I have also asked the forums at EOS since that is my Linux flavor. But I digress, thanks again!

You are calling spawnPipe in you startup hook > myStartupHook :: X () > myStartupHook = do > xproc <- spawnPipe ("xmobar -x 0") > […] but you never do anything with that pipe; e.g., normally you would feed information about the workspaces to xmobar. Note that, in particular, this

is not quite right. xproc is simply a name you give to the handle returned by spawnPipe. Whether you want to use pipes or not, I would suggest going through the tutorial[1] to learn how to correctly set up xmobar. It also tells you a little bit about Haskell, which may be useful when you have to debug something again in the future. Tony [1]: https://xmonad.org/TUTORIAL.html

Hi! It could be because you never actually write to xmobar's stdin. You start the process and store the handle in `xproc` - but it is never used. You need to modify xmonad's logHook to log to xmobar's stdin - something like this: , logHook = logHook myConfig <+> dynamicLogWithPP myXmobarPP { ppOutput = hPutStrLn xmproc } In order to get it all to compile you'll probably need to also move xmobar startup from `myStartupHook` into `main` before actual xmonad startup -- Best regards, Platon Pronko PGP 7A2CB94E On 2022-04-08 18:56, Michael Needham wrote:

Thank you Platon. I think that might be exactly what I was missing. I will make the addition you suggest and I have already moved the xproc line to main. Thanks Again to all and for your kind help and advice. Now wish me luck learning Haskell and I may better understand the “why” of all this. Have a great weekend! Regards, Michael Needham
