luaradio VS luarocks

Hi all, I'm currently working on some control systems and need a high/low-pass filter in lua. I've found a radiofilter library on github but I dont want to use the whole thing, and am not able to reverse engineer the high/low-pass filter part (tried and failed :/ ) and am also not able to derive it from the wikipedia page.

You can do this using Luaradio. From the example here : https://github.com/vsergeev/luaradio/blob/master/examples/rtlsdr_rds.lua and here : https://luaradio.io/examples/rtlsdr-rds.html replace the line local source = radio.RtlSdrSource(frequency + tune_offset, 1102500) by by an (IQFileSource)[https://luaradio.io/docs/reference-manual.html#iqfilesource] : local source = radio.IQFileSource('/tmp/myfile.cf32, 'f32le', 1102500) Take care to the samplerate, or adapt the script to your samplerate. Tip: use luaradio -v to check samplerate coherence along the chain.

Instead maybe have a look to this jewel : https://luaradio.io/ Easy to install (a couple of dependencies and a simple copy from git). Using scripting instead of GUI, and based and blocks. Latest version includes built-in applications for demodulation and decoding. Well documented with valuable examples, easy to understand. Linux only, all platforms. I'm a big fan.

Good news. Following informations on this link (https://github.com/vsergeev/luaradio/issues/64) , I was able to write a little GUI using luaradio embedded in love2d script, change/display frequency using keyboard shortcuts. That was just a quick test, really interesting ;) Have to find the files on my backup.

LUA_INCDIR is not listed on either https://github.com/luarocks/luarocks/wiki/Installation-instructions-for-Unix or https://github.com/luarocks/luarocks/wiki/Installation-instructions-for-Unix but luarocks complains that it's not set. What does it do?

Luarocks packages (or "rocks") provide a rockspec, which luarocks uses to build the package and resolve dependencies.

The luarocks.loader module is provided by Luarocks and basically replace the standard require function by a version that handles Rocks installed with Luarocks (https://github.com/luarocks/luarocks/wiki/Using-LuaRocks#multiple-versions-using-the-luarocks-package-loader and https://github.com/luarocks/luarocks/blob/master/src/luarocks/loader.lua). Note that this is safer than your implementation since it "knows" the running Lua version and the corresponding Luarocks installed files. So it will automatically load modules at the correct version / path (without additional set_path and hard coded string).

I would reccomend you use luarocks for the project. It’s the “standard” package manager for lua, and supports building the C parts (using autotools). It also manages the dependencies for you!

What kinds of trouble? It looks like it's under active development https://github.com/luarocks/luarocks/commits/master ...have your troubles with it been specific enough things that you could post them in the issue queue?

what luarocks version are you running? If it is the one from luaForWindows, then I recommend upgrading it (https://github.com/luarocks/luarocks/wiki/Download). Solved my include problems but requires a bit of configration
