fatal error: module 'LuaSkin' not found

[farzadmf]

Hi, I'm super new to Hammerspoon, and I saw a post somewhere that required the spaces module from here.

This is how I'm trying to install:

1. Clone the repo
2. Go into spaces directory
3. I have an Intel Mac, so I do make install-x86_64
4. I get the following error:

Skipping Lua Compile Verification
mkdir -p ~/.hammerspoon/hs/spaces
install -m 0644 init.lua ~/.hammerspoon/hs/spaces
test -f docs.json && install -m 0644 docs.json ~/.hammerspoon/hs/spaces || echo "No docs.json file to install"
spacesObjc.m:2:9: fatal error: module 'LuaSkin' not found
@import LuaSkin ;
 ~~~~~~~^~~~~~~
1 error generated.
make: *** [obj_x86_64/spacesObjc.so] Error 1

Is there something I need to do? Is this module bundled with Hammerspoon or I need to install it from somewhere?

Probably just easier to download the pre-compiled version here:

Thank you @latenitefilms for the quick reply,

Sorry for the stupid question, but where should I extract the file? As I mentioned, I'm very new to Hammersppon and trying to learn it 😛

[latenitefilms]

Just unzip it and put it in your ~/.hammerspoon folder. You can then use it by using require("hs.spaces").

Thank you @latenitefilms , will update the issue once I try that

Hey @latenitefilms , sorry to bother you if this is a stupid question (I'm new to Mac)

I downloaded and extracted the zip file, copied the files to ~/.hammerspoon/hs/spaces, and when I try to import it, I see the following:

I've learned how to get around that for applications, but I'm not sure how to do that with individual files likes this. Can you please help me?

@latenitefilms pinging you again just in case you missed my last message 😝

[latenitefilms]

Pinging @cmsj as he might have some ideas as @asmagill seems very busy at the moment.

I think you might have to code sign this extension yourself to get around macOS's security requirements.

[farzadmf]

Thank you @latenitefilms . Not sure who to tag here, but that's something I don't know how to do and I'd really appreciate if someone can give some pointers as to where I can find instructions on how to do it

[asmagill]

Sorry, yeah, I'm out of town and somewhat limited in access at the moment...

A while back I did finally get an Apple code signing key, so I guess I should start signing the universal binaries in these repos if I'm going to continue offering prebuilt versions.

In the mean time, I think the following should work for you, though I haven't actually tried it on just a module yet (just the Hammerspoon app when I made local development builds)...

Before I bit the bullet and purchased an Apple developer key, I used a local privately signed key... I used this link for a guide on creating the key... it's a bit dated, I think there are a couple of extra steps now, but if I remember correctly, the defaults should be ok to just click through.

https://bd808.com/blog/2013/10/21/creating-a-self-signed-code-certificate-for-xcode/

Once that's done, you can sign a file (usually only the binary files require it, so for modules, anything that ends with .so after building or downloading) with the following command:

$ codesign --verbose --sign "<SIGNING_CERT>" "internal.so"

<SIGNING_CERT> should match the name given to the key you created in the key chain, and internal.so would be the binary component you're needing to sign.

[farzadmf]

Thank you very much @asmagill for the detailed answer.

I'm not in a rush for this, so I was wondering if you have a timeframe of when you'll be signing the pre-built packages (if you're gonna do it of course).

If not, I can look into the link and try to do it myself.

@asmagill / @cmsj - Curious, if this is an extension that people really want/need - any reason we can't bring into the Hammerspoon core?

We've resisted putting Spaces into the core because it's private API that has had a history of changing a lot, unfortunately.

[asmagill]

As I recall, this version was one I was considering suggesting for core as it mostly leverages accessibility elements of the Dock, and the private API elements it uses are the ones that have remained pretty constant since about 10.8 or so.

Then I got distracted and haven't had a chance to get back to it...

I'm hoping to be back home late Sunday so hopefully I can take a look at Hammerspoon again next week and come up with a timeframe for getting back to maintaining things like this.

[farzadmf]

Hey @asmagill , I hope you got back to your home safe and sound 🙂

Just wondering if there's any update on this

[latenitefilms]

I believe he's been working hard to bring this across to Hammerspoon's core!
