Build on OSX

[erf]

The new LUA addition looks exiting. I tried to install the third party libraries manually, but i think i screwed something up, because i can't see syntax highlighting. This is probably due to LUA or LPEG, but i did not get any errors. Anyone successful at building for OSX ?

[martanne]

Your subject refers to a build issue, but then you state that you do not get any errors (hence the build was successful)? Did you do make install or set VIS_PATH=. ./vis?

[erf]

I ran make and it built without errors but I guess i was making the assumption that some third party library was not working correctly since syntax highlighting was not showing, and that the build process could be improved upon for OSX. But i guess it could be another issue as well. Feel free to rename it.

[erf]

I did do make install

[martanne]

Run VIS_PATH=. ./vis from the build directory. If it does not work, use the Mac OS X equivalent of strace(1) and check what files it tries to open.

[erf]

I ran VIS_PATH=. ./vis but i get the following warning:

Warning: failed to load theme `default-256' set $VIS_PATH

I believe it's because lpeg is not properly installed, and i'm not sure how to install it. The make local does not work.

[martanne]

I assume you have built lpeg using make macosx? After that you must place the resulting lpeg.so file somewhere in the lua package path. Start the interactive lua interpreter and execute: print(package.cpath).

Anyway, except for the non-existing error reporting this is not a vis issue ...

[erf]

Got it working by putting the lpeg.so in the right place.

I'm surely lacking some know-how in the linux / unix world, but automating the install process for vis on osx would be sweet.

@erf Once there is a version we can look at getting it on homebrew.

[erf]

@twe4ked Yes let's do that.

[martanne]

@twe4ked did you ever start packaging for homebrew? This would at least partially cover #162.

[twe4ked]

I had a quick look into it over the weekend but I ran out of time. I'll try get around to it soon.

[martanne]

Thanks, looking forward to it! I had a quick look at the package repository, both libtermkey and Lua 5.2 are already packaged and should not cause any problems. LPeg might be a bit more tricky because homebrew seems to have some issues with Lua dependency management? The sile formula refers to it in some way ...

[twe4ked]

I've opened a PR to add vis to homebrew.

Edit: It conflicts with an OS X app so hopefully it's allowed.

[twe4ked]

There were a few issues with the PR that I've fixed up. Here's what it looks like to install. The lua dependencies and the vis(1) conflict make things a bit more difficult.

[martanne]

Thanks! So the installation procedure would be:

$ brew install lua && luarocks-5.2 install lpeg
$ brew install vis && brew link --force vis

Better than compiling from source I guess. Not sure why homebrew does not manage to properly handle Lua dependencies.

As for the name clash, I was aware of it, but at the time thought it would still be a fitting project name. Partly because of cat -v considered harmful which is the reason the original vis command exists. After all a goal of vis (the editor) is to handle arbitrary files and visually display them ...

The other main reason is that the computer science student organization at my university is also called vis, and they "sponsored" development with their free coffee service. Because the starting point for the whole project was a university course covering Project Oberon this reference seemed appropriate.
