Calling charging from xterm by 1/2 short commands seems reasonable for script, that works from xterm anyway. Forcing user to *always* do charge.sh, or modify scripts itself to get rid of it, isn't fun. Nor it resemble the "ideological" Open/Linux way of doing things.

Of course, if it gets implemented as "force to use it", I can live with that, and modify script / fork it if others would be interested in using such version (like it was for a long time with backupmenu, and backupmenu-multiboot - while, t was very easy to implement one version working for all). After all, final decision belongs to blue_led. Still, I don't think it's good idea, to *force* such commands on user.

Not to mention complications on script-side (determining, when it should do boostoff/charge, or not - trying that without external power source would break hostmode), but that's different topic.

dude, H-E-N is first and foremost meant for mobile hostmode where you can not charge and need vboost power from device.
I'd never suggest to change that to a "you need an external power supply or it won't work".

What I thought of though is displaying a notifier "if you want to use charging, plug in your power supply NOW!", then for maybe 5s detect/check if there's already 5V applied, then depending on the result either enter charging hostmode or vboost hostmode. In the specs for my never finished jrbme/hostmode script this was dealt with by parameter --power-auto (as opposed by --power-external and --power-vboost [default]).
[edit] anyway note that due to speed settings need to be done with NO vbus power applied, any external power supply will be mutually exclusive to speed autodetection :-S (blue-led will know what I'm talking of, as he already implemented vboost joggling to do the speed detection)[/edit]
Further related parameters were --power-notify-timeout <seconds>, with "0" meaning that user has to click on "ok" in that notifier, and there's been another specified parameter --power-manual which would open a "charging? yes/no" requester. Quite obviously any script (also) for charging hostmode needs to wait for external power to get applied before ENUM etc gets started. And once we started vboost we can't detect presence of external power anymore. Thus the above sketched scheme.

:-D :-D
cheers
