Missing fonts in wavemon? #50

sliddjur · 2018-05-22T09:30:02Z

Hello I am missing some fonts when I start wavemon. I am using fresh install of Ubuntu 18.04 and both gnome terminal and tilix terminal shows the same font error (I suppose).

Troubleshooting steps:

check locale settings: https://help.ubuntu.com/community/Locale
ncurses requires ANSI escape sequences, your $TERM should support this (known working examples are xterm and vt100)
try running this from xterm, after checking locale.

@sliddjur - has this been resolved, did you find a fix?

@grrtrr I installed xterm from apt. It still looks the same.

olof@olof-ubuntu ~> echo $TERM
xterm-256color

In xterm app, $TERM is xterm.

Thanks for getting back. I still think that this related to locale settings, of which there are quite a few.

In the above picture the 'funny' characters appear between

thousand separator for RX/TX (220,293 and 226,402 respectively);
thousand separator for retries (number seems to be 2,904 but is cut off -- seems a lot).

The numerical setting is set via the LC_LOCALE, which is in turn affected by other settings.

In addition, instead of a dot (".") the dBm setting above uses a comma ("1,26nW"), which is unusual. This too would indicate an unusual locale setting.

Under the hood, this is all done using the setlocale() call.

All of these settings can be bypassed by setting LC_ALL.

Can you please try this: export LC_ALL=C, and then run wavemon?

Likely you will then have no thousand-separator between numbers. If that works I can take it from there, maybe the use of setlocale can be improved.

yes, if I set export LC_ALL=C and run wavemon, it works.

Thank you. I will work on a fix that does not require setting an environment variable. The downside is that it will use US/GB numeric separator (a . between 1 and fractions of 1, and a , between groups of thousands). This may look strange in other countries, but is still better than the funny fonts - which might have to do with the ncurses library.

This caused funny fonts to appear in some locales. Replaced by using a custom function which switches to pseudo-scientific notation for larger counts.

As promised - if you are able to compile from master, could you give the above a quick run?

It should resolve the locale-specific issues. It is now locale-independent.

sliddjur · 2018-09-04T12:07:52Z

It looks better now.

Thank you, I will integrate this into the next release.
