Limited number of modules

[ChouangTseu]

Hello unix121,
first of all, thank you for your work; I like what you did.
I successfully installed everything on my machine, and it seems to be working well in general. However, I would like to have more than 4 modules with polybar. Currently it shows: the wifi; the workspace numbers; the time/date; the power button. I would like to add cpu & memory usage, battery status, xkeyboard, and volume.
Modifying the polybar config file, I tried to add a few modules, but they do not appear on the bar on restart. I guess it has something to do with the parameters in the section [bar/i3wmthemer_bar]? Or do I have to change some other config file in the /i3wm-themer folder?
Here is my polybar config file:

I would appreciate if you could help me out.

Hello sir,
All you have to do is change those lines:

modules-left = wlan eth
modules-center = i3
modules-right = date powermenu

to:

modules-left = wlan eth
modules-center = i3
modules-right = battery cpu date powermenu

Reading the documentation of 'Polybar' would help you.

Thank you. Adding modules to the lines you mentioned does the trick... as long as I don't switch the theme. Whenever I switch, the added modules disappear from the config files, meaning that the lines revert back to the default:

modules-left = wlan eth
modules-center = i3
modules-right = date powermenu

How could I keep the polybar config file intact when changing a theme?

I don't know if it's of any importance for the question, but since I installed the themer, most of the Fn keys do not respond anymore; also the alternative keyboard layouts I had configured seem to be inaccessible via my usual Alt+Shift shortcut.

Hello again sir.

I've thought of a way to fix this issue by adding tags to the lines that must be changed through the there. It needs a bit of work but I might be able to pull it out some time soon.

About the Fn thing, most of those keys are configured inside your ~/.i3/config file, so if you have saved a backup of your original config file, just go in there and copy-paste them into your new ones.
