Love Command-line How-To

[sanyaade]

Hi All,

Good day to everybody!

I am a newbe here and I am trying to use Love 2D with my 14-16 year Students. My Questions are:

1.) Is it possible to run Love 2D within and ide? For example from within Scite or any ide like compile and run mode.

2.) Is there any information on running Love 2D from command-line? If so where can I find the information?

We are using Windows XP

Any pointer, guide-lines, advices, examples will be highly appreciated.

Thanks in advanced and Happy Xmas!

God blesses!!!

Best regards,
Sanyaade

Command-line:

Code: Select all

love.exe "folder, zip or .love"

IDE:
Notepad++. Take a look at http://love2d.org/forum/viewtopic.php?f=4&t=235

Thank you Kaze! Thank you everybody!

I have tried the .love command-line with some of the examples/demos but does not work. The folder command-line seem to work once but in most cases I get error --> Game (F:\Love2D\LOVE\example1.love) does not exist." but the file does exist and same with other tried files. Some of the files are actually those that case with the Love package.

Is there anything I am doing wrong?

Is there documentation or any text on running love from command-line that I could consult or do I have to consult the Lua documentation on Lua website? I went through the love 5.0 document but I could find anything or command-line.

I will like to start using Love with the students by 5th of January 2009, so I am ready to learn and explore.

Thank you for your support.

God blesses!!!

Hi sanyaade, welcome to this lövely forum

I'm not aware of any documentation on the topic and the Lua docs will not contain any clues since command-line parameters are managed by LÖVE itself and not Lua.

Now, as Kaze said, LÖVE expects its parameters in one of the following forms:

Code: Select all

love.exe my_game.love

or

Code: Select all

love.exe my_game_directory

On my tests (on Windows), LÖVE seems to do fine with stuff like

Code: Select all

love.exe demos/no.love

but fails to open stuff like

Code: Select all

love.exe C:\Program files\LOVE\demos\no.love

But Kaze's link seems to suggest otherwise, so colour me confused

[Kaze]

but fails to open stuff like

Code: Select all

love.exe C:\Program files\LOVE\demos\no.love

Program files, there's a space, so it takes it as two arguments. It needs to be in quotes like this:

Code: Select all

love.exe "C:\Program files\LOVE\demos\no.love"

I fail at Windows, period. Thanks

Thanks Merkoth! Thank you everybody!,

Merkoth, I think it is the path problem as I am investigating now. I did the following and got the following errors:

Case 1.) On Windows XP:
1: I copy the love program to f:\love, then I run the cmd and cd to f:\love
2: I copy the animations.love from the demos folder to love directory then I issue the command:-

Code: Select all

 love.exe animations.love 

I got the stderr:- Game (F:\love/love) does not exist. It seems to be appending extra folder argument to itself. If I cd to F:\ (root drive) and I issue the same command:-

Code: Select all

 love.exe animations.love 

then the love program starts up and about to show its window but then died, the stderr was:- Game could not be loaded. By suprise if I drag the file --> animations.love onto the love.exe, it runs smoothly but I dont know how it works internally (know this may help). But we definitely having path level problems here!

3.) I am going to download more love packages (may be perious ones -> just to see if command-line used) and current source code to see the API and the extern interface, hopefully the problem will surface.

Thanks in advanced!!!

God blesses!!!

Maybe I'm missing something, but if love.exe is located in f:\love\, calling love.exe from the root directory shouldn't be possible at all

By the way, the LÖVE installer automatically binds the .love file extension to love.exe, maybe you can use that? It'll be kind of annoying for your students though, having to create a zipfile and rename it each time they want to try their projects.

In any case, I strongly suggest to follow Kaze's advice and use Notepad++ as shown in the link he posted before. Notepad++ is a feature-packed, free open source text editor. IMO, it's also easier to configure than SciTE.

All of these worked for me: (Windows XP)

Code: Select all

C:\Program Files\LOVE>love.exe "J:\Lua\LOVE\Text box.love"

C:\Documents and Settings\Compaq_Owner>"%ProgramFiles%/LOVE/love.exe" J:\Lua\LOVE\test.love

-- I copied the LOVE directory to the J drive
J:\>"LOVE/love.exe" Lua/LOVE/test.love

J:\LOVE>love.exe ../Lua/LOVE/test.love
J:\LOVE>love.exe J:\Lua/LOVE/test.love

No problems for me.
