print unicode music symbols with lua

[reddiesel41264]

How does one output Unicode symbols with Lua inside Reaper?

Thanks

I'm giving this post a little bump and I also want to ask is it possible to use external Lua libraries inside Reaper?

[reddiesel41264]

For those interested I figured out a couple of ways to print Unicode characters. You have to use a hex notation or use the utf8 library.

The two links below showed me the way
http://www.lua.org/manual/5.3/manual...utf8.codepoint
http://lua.2524044.n2.nabble.com/Uni...td7056298.html

I also found this useful tool for converting between "U+EA03" style notation and hex and decimal.

Thanks for posting your findings in the absence of any replies.

To draw U+EA03 for example, you can use reaper.drawchar(0xEA03), which will do the unicode conversion internally. Also, reaper.measurechar(0xEA03) will give you the dimensions of the character in the currently selected font.

Ah, that's much better. Thank you!

I got an error with reaper.drawchar but gfx.drawchar worked
Any news on the includes, I keep getting messages that Reaper can't find the files, I'm using things like require "myluafile". And should it also work with .h files?

[schwa]

Right, gfx.drawchar.

require and dofile should work. If the files aren't being found, it's probably a path problem. Remember that lua paths are wildcard patterns, not just directory listings.

Cool, thank you

reaper.drawchar(0xEA03) draws an empty rectangle here and not the correct character

gfx.drawchar(0x1D15D) does not draw anything, while it should draw a whole note (at least with Reavura). Any ideas?

BTW, is this supported? :

gfx.setfont(1,"Reavura", 60)

I can confirm, that it seems to use Arial on Windows instead...

At least it looks identical...

gfx.init("")

gfx.setfont(1,"Times", 60)
gfx.drawchar(65)
gfx.setfont(1,"Arial", 60)
gfx.drawchar(65)
gfx.setfont(1,"Reavura", 60)
gfx.drawchar(65)

tested on Windows 7, Reaper 6.11.

In general, some fonts seem not being supported. I noticed, that you can't use all installed fonts in video-processor as well, only a handful.

Edit:
Yes, it seems like it can't find the font and uses Arial as default instead, like the following example loads the exact same font.

gfx.setfont(1,"", 60)
gfx.drawchar(65)

Thanks for testing mespotine!

It would be nice if at least Reavura was supported.
