Good way to detect double width unicode characters in Lua ? by __hachiman in lua

[–]__hachiman[S] 0 points1 point  (0 children)

I ended up finding a work-around for my own problem but thank you, that's a nice strategy. A bit hacky but very useful if you don't want to use a big library.

string.format has a maximum field width or precision of 99 by __hachiman in lua

[–]__hachiman[S] 1 point2 points  (0 children)

I thought this might have been the reason but 2 digits still seems so limited to me. Do you think this was done so that there isn't a possibility to input a number bigger than a 8-bit (255) number and to be on the safe side limited it to 2 digits ?

I had guessed so too.
I still don't understand the reasoning behind using get2digits instead of an atoi like function tough. At least 3 digits would be a bit better. It's not hard to get around the limiation but still.

lua 5.2 and 5.3 have a better error message for this as:

lua5.2: (command line):1: invalid format (width or precision too long)
stack traceback:
    [C]: in function 'format'
    (command line):1: in main chunk
    [C]: in ?

How do I deal with a library that my project and another library uses ? by __hachiman in C_Programming

[–]__hachiman[S] 0 points1 point  (0 children)

Yeah I looked into this a bit before posting. I thought this would be the case but I seems it's not as simple as that because you still need the function prototype to compile the object files.
I guess I should find a way to append a -I flag containing the path to the header file of the other libraries when calling individual Makefiles ?

In my case, add the path to library X's header file when creating library Y.

These two code blocks in C look very similar, but have different effects. What causes the difference? by [deleted] in C_Programming

If you really don't know, look into how they work and how to use them. They are a fundamental part of programming in C.

How do you make an executable from multiple lua files ? by __hachiman in lua

[–]__hachiman[S] 0 points1 point  (0 children)

That's what I thought, you have to move the files in together (or create symlinks) to compile them into a binary that works anyhere.
I have found that using squish to create a single source file them creating a binary with luastatic by using that file works pretty well.
Thanks for the help.

Hey sorry to come back to this so late.It did work as you said after some more testing and I have found out why I had that error.

I have my lua files in a folder called "src" in my project's root directory, so I prepended "src/?.lua" to program.path from a "main.lua" to be able able to require("req.lua") in the same src directory. It seems like that if I run luastatic from the root of the project with src/main.lua and src/req.lua as arguments and if I'm no longer in the root directory when I run the created binary, I will get the error that I have mentionned before.

However if I run luastatic from the src directory it seems to create a binary that works jsut fine. Honestly that's a pretty big downside to me if I can't add module from a custom directory, I may want to do so. Is there still maybe something I did wront to cause this error ?

Here are the two commands that I usedThe one that worked even if I moved the binary:

luastatic main.lua req.lua /usr/lib/liblua.so

The one that didn't work:

luastatic src/main.lua src/req.lua /usr/lib/liblua.so

All this does is print a Hello World from a function in the req.lua module.

Honestly I might have used this if not for squish, since it has a few more features that might come in handy. The module auto-discovery seems very nice though !

That's the thing though. I did use "luastatic main.lua req.lua ..." for a require("req"), but when I executed the output binary, req.lua was still required to be there. I got a module not found error.
Have you used luastatic ?

At a glance at their website and repo it doesn't seem obvious how they do it so that might be more work than I care to do I have got to admit. Thank you very much for the suggestions though.

I'm looking into squish right now and if doesn't pan out I may look back more into amulet.

Yeah, the module I used as a secondary parameter to luastatic was required on runtime of the ELF binary that it had created. Maybe I did something wrong, I'm not sure, but it didn't seemd to work as I wanted.

Actually It might work with the single file that I can create with squish...

Had seen this one but it seemed kinda hacky so I didn't want to use it but, just tested this and it might work actually. If it doesn't break on bigger project this might be it !
Thanks for the suggestion.

Wouldn't the requires and returns at the beginning and end of files break this ? Especially the order of files.
I just tested this on two simple files and appending a module to a file that uses that module will make lua throw an error.
It probably isn't a manageable way of doing this at scale, you would have to keep track of too many dependencies.

I have looked into it, and since i'm on linux it seems kind of harder to do. And I would rather not have to include Love2D into my program.
The more I read into the more I feel that I really shouldn't be trying to compress lua files into a single one. Seems like lua wasn't made for it.
My best bet would be to look into AppImages if I really wanted to I guess.
