08:31:21	speachy	looks like bluebot is MIA, so as a heads-up, the re-adding of mpegplayer is currently building.
08:31:42	speachy	I'm not terribly happy about it, but such is life. :)
08:33:17	speachy	othello7: you should be good to rebase against git master now

09:03:12	spork	next time you want a discussion, you know the approach
09:12:52	spork	it is also a great way to notice how many people still use a feature and rockbox in general

09:52:09	speachy	there's not much desire to nuke (working) features in general
09:53:37	spork	no, but other than downloads it is hard to guess how popular/relevant a software project is
09:53:59	speachy	we don't even have that. :)
09:54:50	spork	or even features
09:55:08	speachy	So on average mpegplayer is a 1.7K bump in core image size, ranging from ~300B to over 3KB.
10:00
10:01:51	speachy	it would be interesting though, adding some sort of analytics.
10:02:48	speachy	eg keep counters of every time a plugin is launched, along with our uptime, codec, players, etc. have rbutil collect and upload them.
10:03:11	speachy	unfortuantely rbutil is probably only ever used once, if ever...
10:03:16	speachy	no itunes-like lockin

11:29:33	amachronic	speachy: to my surprise I successfully built a freestanding mips C++ toolchain with GCC 12.
11:30:34	amachronic	the options I used are here -> amachronic/31222be96330f85362751c3ee844b23b">https://gist.github.com/amachronic/31222be96330f85362751c3ee844b23b
11:30:59	amachronic	this does not work on GCC 8 though, I already tried.
11:36:05	speachy	ah, thanks for that! glad to hear it's been fixed upstream. Maybe I should have been more ambitious..
11:40:26	amachronic	sticking with GCC 8 is probably ok for now
11:40:54	amachronic	c++ is still unusable because the rb headers do a lot of things that isn't legal in C++
11:40:58	speachy	The odds of any c++ we'd want to use working in a pure freestanding environment are slim
11:41:22	amachronic	just try turning on -Wc++-compat...
11:41:38	speachy	we already have C++ support turned on in our hosted toolchains fwiw.
11:41:51	speachy	... so I guess we should start cleaning up our headers. :)
11:42:19	amachronic	that'll consume the next 2 years until we update to GCC 12 ;)
11:43:20	amachronic	and yeah, we are definitely going to need to port a hosted c++ stdlib to rockbox for it to be of any use.
11:45:51	speachy	what does (eg) arm's mbed use?
11:47:54	amachronic	not sure.
11:50:33	amachronic	"modern c++" is probably nightmarish on a microcontroller.
11:51:41	speachy	heh, less so than "older c++" :D
11:52:01	amachronic	yeah, there are some newer stdlib features like polymorphic allocators that could be useful.

17:54:18	othello7	speachy: thanks! I just built latest. all this has reminded me about how great rockbox is and I'm probably gonna finish the dodgeblock rockbox port
17:56:13	othello7	one of the issues I have is that I couldn't find a bigger monospace font. I saw how to change the font but all available fonts are not fixed-width. I was thinking I might just do what the N64 port does which is to use a spritemap font and just have that be different based on the screen resolution.
18:00
18:08:19	braewoods	othello7: you need a bitmap monospace font? I know one that covers a large range of options.
18:08:57	braewoods	Terminus, Fixed (the original font used in X11 even), and maybe other Linux console fonts.
18:09:50	braewoods	Fixed had the most options that I recall. It might be possible to convert to a compatible format.
18:10:03	braewoods	PCF fonts were the norm in the old days of X.
18:10:19	braewoods	https://fontforge.org/docs/techref/pcf-format.html
18:11:25	braewoods	I used to love Fixed back in the lower DPI days. These days I prefer ttf and the like.
18:24:05	othello7	oh neat. I did have the font from my N64 project but this looks nice. The question is, how would one use a custom font other than just using a spritemap?

18:45:57	braewoods	othello7: no idea, not an expert on fonts for embedded setups. I just suggested some older ones that might work out if you can convert them to a compatible data stream.
18:53:29	speachy	IIRC we do have a monosppaced font, Terminus. not a full set of sizes but it's there.
18:55:08	speachy	it's also not installed by default but it part of the separate font pack

23:00
23:40:20	othello7	ah, I wonder how one would address that consistently from a plugin. also would it be possible to draw text in a manner in which it would be easy to change the color?
