.sm to .dwi converter

Re: .sm to .dwi converter

So I'd actually be doing something with my time, I started going through some lessons in Ruby a few days ago. The first original script I made was to count left- and right-hand arrows in a simfile to check global bias.

Then I saw your Lua script and found it interesting how nice all the stuff with the tables and fields look. I'm wondering, though, what does the most recent version of your script look like? I'd like to see how you fixed the latest version you've linked to.

Arf, but, so I thought I'd try to make one in Ruby ... I've worked a couple days, and here's where I am.

It looks really chunky, some of the stuff I did is convoluted, I didn't put comments to say what any of the weird stuff does, (and it certainly doesn't look as nice as yours) ... but it's worked for the .sm, .ds, and .ssc files I've tried ... as long as they have only one difficulty and only tap steps. This will only be used for files for FFR, so I didn't try to do anything more.

The code:

The executable:

dwi2

MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.

Throw dwi.exe into the folder with the file you wish to convert, double-click/run it, and watch a .dwi file magically appear out of nowhere.
I'm sooo not like trying to "steal your thunder" or however you say it, so I'm sorry if this irks you like even the slightest bit, me just doing this after you've been working so hard and you know and sorry and uwrawrf
EDIT: I realized the script had a mistake in it like three weeks ago (used ' instead of ` for opening 192nds) but didn't bother to fix it for this, because like one person downloaded it when I posted it, and I didn't think anyone else would. But I saw it got a second download, so I just uploaded a fix. The batchdwi executable in my second post has already been fixed.

Re: .sm to .dwi converter

Not sure how I can help, but if you do need any let me know.

You are a champ for taking this on.

Hey, thanks to the both of ya. I can see how this could help for steppers who don't use 3.9.

Re: .sm to .dwi converter

for those who are interested, here is a pastebin of the source:

dwi converter - Pastebin.com

http://pastebin.com/MHJtWLXA

Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.

some things might be a little sloppy, and i'll work on improving them later. i just wanted to write something that works for now.

this will successfully convert a file named "test.sm" to "test.dwi". this assumes, like silvuh's script, no holds, mines, etc.

i have yet to implement directory searching. going to work on that soon. after that, i'm going to add recursive conversion from a root directory to convert a whole bunch of files at once. that way, everybody can send .sm files to batches instead of having to convert to .dwis

Re: .sm to .dwi converter

haha, it's not quite done yet. it will work if you have lua installed on your pc, but i really want to make this a standalone executable.

going to edit the op with what i have so far in terms of code from now on and my future direction.

Re: .sm to .dwi converter

This is excellent. The .dwi format has never made sense to me. Keep it up 8)

Re: .sm to .dwi converter

Awesome! I was actually thinking about making one myself.

Ohh, I didn't even think about that! Yeah, it would definitely be more convenient to be able to convert all batch files at once than having to make everyone convert their own files before sending them in.

I added the following lines to my script: ("..." is where all the old scripty stuff goes)

Code:

Dir.glob("**").each do |folder|
    next if folder =~ /.*\..{1,2}[^\)]$/
    Dir.chdir(folder)
...
    Dir.chdir("..")
end

These lines makes the old script loop through each folder in the directory ... so it now works for batches if you put the .exe in the song superfolder.

Here's the new executable:

batchdwi2

http://www.mediafire.com/download/kkuchnajxr80mf2/batchdwi2.zip

MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.

Extra notes: It only searches one directory down. The "next if" line is so the script skips any file with any two- or three-character extension without skipping anything ending with ")" (as all files in the batch should; it won't confuse a file with stepartist "asdfk.as" as not being a directory.) Without this line, the script would break when it tries to enter "batchdwi.exe".

I don't know how to make the executable show a pop-up if it catches something that FFR doesn't support in a file, but that should be something the stepartist should check before sending the file in.

... And I don't know how to search directories and files and stuff in Lua, but here's an explanation of what I did in Ruby in case it helps:

Code:

filearray = Dir.glob("*.{sm,ds,ssc}")
simfile = open(filearray[0]).read()
dwifile = File.new("#{filearray[0].sub(/\..+/, "")}.dwi", 'w')

This Dir.glob expression saves the file name of every .sm, .ds, and .ssc file in the folder into an array. The next line opens the first entry in the array and reads it (so it will read a .ds file if no .sm is present and only read one file). The next line creates the .dwi file, naming it by substituting the file extension of the simfile with nothing and sticking ".dwi" onto it.

Re: .sm to .dwi converter

if I remember VB, I'd convert this to a standalone but the only thing I'm working with is powershell lol

can you package powershell scripts?

i'm not really worried about this yet. in terms of lua, my approach is probably going to be something along the lines of returning data about the conversion process in a lua table to c and using c to handle said data.

http://keplerproject.github.io/luafilesystem/

lua doesn't offer as extensive of a file io library as ruby because it is designed to only include what is maximally portable. luafilesystem isn't quite as portable as the base io libraries, so that's why it isn't included in the standard lua libraries. it will offer all of the functionality i need, though.

**Fission** · 07-19-2013, 04:32 PM

Re: .sm to .dwi converter

updated op. removed some silly unnecessary code and cleaned up some of the structure. going to work on compiling luafilesystem into a c library in the near future.

**Fission** · 08-4-2013, 04:41 AM

Re: .sm to .dwi converter

updated op with new version of the script. recursive searching and converting should work now. going to work on getting a standalone executable out now.
