I have been working on a small script in Python for some time now and I think some people would appreciate.
I have always, from when I first started playing osu, wanted to be up-to-date with all of the new maps that are available.
Keeping up with the beatmap packs is a bit of a hassle, and somehow people are still having issues with them.

What I've made is a auto-downloader that works through Bloodcat (my favorite beatmap mirror).
Just a quick explanation as to what it does.

I know the code isn't pretty or the best. I'm still learning Python, but it works on my side and wanted to share.
I've also gotten hold of the owner of bloodcat. "I'm very happy that people makes application with my site." -방성환
I just wanted to get the ok from the owner before posting the code for everyone to use.

Downloads
One thing you will need before running this script is either Python 2.7 or 3.4.
The current version of both are 2.7.8 and 3.4.1.

Now for the script.
The code for Python 2.7 can be either viewed of downloaded from here.
The code for Python 3.4 can be either viewed of downloaded from here.
This only includes the auto-download.py file. The Recent.num file will be created when you finish a download.

I am trying to learn how to make a GUI for it. I will update this page if/when I ever get finished with it.
I hope you enjoy it.

P.S.: Once started, you can minimize the window. It will run in the background and beep if there are any errors.

P.P.S.: As of Aug. 14, 2014, I've been taking my Advanced Systems Project class and started making a GUI application in Java. I will be learning more in depth about GUIs in the next few months.

Updates

Off to a good start, just one thing I noticed:

conn = urllib2.urlopen('http://bloodcat.com/osu/?mod=json')
data = conn.read().split('},{')
conn.close()
items, s = [], ['{"id":', 
				',"artist":"',
				'","source":',
				'","title":"',
				'","date":']
for l in data:
	items.append([l[l.find(s[0])+len(s[0]):l.find(s[1])],
				l[l.find(s[1])+len(s[1]):l.find(s[2])]+' - '+
				l[l.find(s[3])+len(s[3]):l.find(s[4])]])

Doing it like that maybe works, but might break with slightest layout change ( even when actual data behind it is same ).
So you are better off just using standard JSON parsing functions.

import simplejson

url = "http://bloodcat.com/osu/?mod=json"
json = simplejson.load(url)

id = json[0]['id']
artist = json[0]['artist']
source = json[0]['source']
title = json[0]['title']
date = json[0]['date']

Or something like that.

To be honest, i only thought JSON was something for bloodcat.
I've never herd of if before looking at the information page.
There are still a lot of things with Python i still don't know about.

Thank you Hexide and Avail for showing me this.
I'll look into this a little more and will see about updating it.

Edit: I have changed the code a little bit to use the json module.
I will have this test for about an hour while i get lunch.
If there are no errors by the time i get back, i'll update my code using the same link on my first post.

Edit 2: It's been running well for an hour now and have just updated the file. Same link in the first post.
ps. i love mediafire's edit file. Don't have to reupload files if it's a small change and keeps the same link.

I have just finished the code working with Python 3.3 and added a couple extra things.

Good way to start!
(I would release my downloader months ago but it's based on some parts of osu site(but uses bloodcat to dl) so it's no-go for mass use)
suggestions:
-Ask if user want to download only ranked beatmap sets or all (or only unranked?)
-ability to download upto ~60(or more)last ranked maps(I think I could provide public api for this- not promising tough)

This wouldn't be too difficult to add.
Having 2+ windows pop-up isn't something i like for small options like this.
Definitely something to remember if / when i make a GUI for it.

I don't think checking the last 60 updated songs every time will do much. Maybe at just the start.
20 is what json brings up by default, and that seems to work quite well.

Thread is about 5months old, would not surprise me if the program was broken by an update to the bloodcat website or something similar

I'm sorry for not replying earlier.
I've fixed the issue. Bloodcat no longer provides the source of the songs any more.

I've been busy with my Java class in college and have had hardly any time for anything else.
I'm thinking of making a Java version of this. Almost everyone has java so no need to install python or downloading the appropriate version of the code depending on what version of python you're using.
Also, GUI's in Java is much easier to understand than python, imo.
I'm still not very good with them though.

Just updated my program again. Bloodcat no longer stores the genre or status as an integer. Everything is strings.
Was asked by neptune23 how to get it working and decided to check to see if it was still working. It wasn't.

I can no longer use my own program every day. My ISP has put a data cap on my house. 300GB split 5 ways.
One more reason why i hate Comcast. No matter how fast your internet is, the cap is the same.
And I've checked other ISPs. It's all i have in the area...

Edit.
One more small edit. I don't know why this wan't in there in the first place.
Added status code 8 for Qualified maps.

How do we make it so that it downloads to a specific folder without asking us to later on?

I did not add anything like that to this program. I haven't touched this program for quite some time now, so it's kinda dated.

It throws me a permission error while it downloaded the map succesfully.

I'll take some time to look into this tonight. I'm a bit busy setting up my computer and a few other things while watching over someone's house for a few days.
YAY for no data caps over here.

I've looked around and the only things i can find are:
1) The file is being used by something already, but the file is saved once the program has the entire file and once the file is opened by the default program (osu!) it's moved to the songs directory and unpackaged as all the files for the map. (what i guess happens. i could be wrong, but not too far off)
2) You or the user you are logged in as doesn't have permission to write to that directory. However, it looks like you were able to write one file there in the first place... I assume you're the owner of the computer and also have admin privileges. If not, try with the admin/owner of the computer.

I made a small script to check if you've got permission to write to a directory. You can paste it into a text file, make sure it has the .py extension, and the save type as "all files" to prevent it from making it a .txt file. If it passes, try the downloader again in the same folder.

And for anyone else who wants to try this, this is for python 3.x.

import tkinter, tkinter.filedialog, tkinter.messagebox, os
root = tkinter.Tk()
root.withdraw()
folder = tkinter.filedialog.askdirectory(parent=root, initialdir='/', title='Select folder to test read/write permissions.')

if os.access(folder, os.W_OK):
	if os.access(folder, os.R_OK):
		tkinter.messagebox.showinfo('Directory permission','You are allowed to read/write here.')
	else:
		tkinter.messagebox.showinfo('Directory permission','You are NOT allowed to write here.')
else:
	if os.access(folder, os.R_OK):
		tkinter.messagebox.showinfo('Directory permission','You are NOT allowed to read here.')
	else:
		tkinter.messagebox.showinfo('Directory permission','You are NOT allowed to read/write here.')

I don't know how but it seems to have fixed itself. Thanks alot though for looking into it.

RavenMac, you should make it in java. 1+ is a good idea
Also if it sorted all the ranked from the unranked in 2 folders and kept that up to date would be an awesome addition.

So this is maybe a bit far fetched but it would be awesome if you could make a program that runs in the background that downloads and updates all the maps. Maybe I should start programming something myself sometime :/ I only do web related stuff and it would be good to explore some different areas. If so in what language should I write it?

Python would be a good place to start but java would make it a lot more easier for other people to use it.

I had the same idea as you.

Keeping every map would be quite space consuming, and would also make the game run inefficiently and become a nightmare for reprocessing.

That's what I would've thought at first but it will only take like 100gb (I'm guessing) which isn't that much to me and reprocessing (25k beatmaps) only takes like 2 minutes for me and doesn't happen that often.

Oh goodness, it's been a while. I've just updated the code. One major thing i left out of the code is to set a timeout limit. Personally, i've had the program just sitting at one song or checking one page for hours. Not sure if anyone else has noticed this, because there weren't any messages about this, but it's fixed.

One other thing I've realized, I've used an RSS notification thing for Chrome for some time and have noticed that (either because of the RSS thing or bloodcat) the updates were kinda scattered. It seemed that it wasn't sorted at all and i may have missed an update or new song because of this. So i have gone back on my word and made it check 100 at a time. One problem i can see with this is, it'll want to download 80 songs if you haven't check for 100 songs before. I may add an option if the change between the number of songs last checked and just checked are greater than 20 or somethin like that. Maybe just add the first 100 on the list to start off and keep updating from there? Let me know what yall think.

I've also changed how i save the recently checked items. Instead of using just the IDs, i now just use the entire JSON item array. When comparing with JSON items, if the times for updates are different, then there should have been an update to the song and therefor needs to redownload. And in doing so, I've changed the file used from Recent.num to Recent.json. The program will check to see if you have the .json file first and update, if not it'll check for the .num file and update. In changing the file type, it will delete the Recent.num file and replace it with the .json file.

The last thing i added, and many people probably won't even bother with looking at it, are comments in the code. Basically anything to the right of a # is a comment.



Now for comments. For some reason, i became unsubscribed from my own thread. So i never got notified when yall commented here. Not sure why, but i'm resubscribing again so this shouldn't happen again.

I'm workin on it. And (much more likely than with Python) maybe a GUI.

Language is all personal preference and what you know. As for doing this, each song added to osu is given an ID. You could see about gettin all of the numbers in a list/array and maybe checking the date created on your computer and comparing it with the last update on osu or bloodcat. I know osu you'll need to get permission to get the API for it, or somethin like that.

This is the reason why i'd like to make this in Java. That way nobody would have to download anything for it...That is unless they don't have java...

Space consuming? Yes. Game running inefficiently / Reprocessing nightmare? Eh... it depends. Having a ton of songs, i haven't seen much problem playing the game. Preprocessing though, that takes a few minutes though.

I've got a folder of just the .osz files and then the songs folder. My songs folder is over 116GB with 16K song folders and almost 50K maps. Reprocessing takes about 2-3 minutes. It does add up, but i'm a very patient person. And i have 6TB of storage and am looking at upgrading fairly soon. So it's nothing.

Just updated the code a little bit more. I'm not sure how much detail i should go into what i've changed, so i'll just cover basics. I changed the song info display while downloading. It now shows what number of however many songs you are downloading (downloading 2 of 5). If there's an error, it won't display all of the info again. Just the id artist and title plus the error message.

I changed two functions and added another. One to cut down coding a little. The other was the song info function. Just a slight change. The added function is used to return the song id artist and title to a few parts of the program. It also can return the unicode info if needed.

I've added a little more information in the error messages. It gives a message as to what function the code had an error and then the regular error message.

Not a huge update, but i was mainly hoping to get the display for how many songs are being downloaded finished. Not entirely sure if there will be another update for python, unless asked for.

Sorry for the late reply. I was attending a convention.
For some reason when editing the code on Mediafire, it converts the first tab into 4 spaces.
I have to reuploaded the code in order to prevent this.

I'm getting this error for some reason.

Saving the beatmap without unicode characters fixed the problem for me.

EDIT

I know exactly what the problem is. I've noticed this on a few songs before. When it grabs the title and artist, sometimes there are unicode characters in them. I've updated the code.

And for a side note. I'm no longer using mediafire to share the code. I'm using pastebin now. I hope this will help when making small edits like i have been doing. For some reason it saved my last edit as one entire line. With some programming languages that's fine, but not with python.

Is it even possible for it to check all the songs you have and download the ones you don't?

Aistify wrote:

With this code, no.
However, it can be done.

I've got some relatives coming in today, so I'm gonna be busy for a little while.
I can look at doing this afterwords.

Hangs on the first song, with or without unicode

I've just downloaded and tested downloading 4 songs with each for 2.7 and 3.4

2.7:

3.4:

Make sure you're using the 2.7 code with Python 2.7 or 3.4 with 3.4.
There are slight syntax differences between the two and some components are named differently.

Also without a screen shot or description of what's going on or what the error is, i can't help all too much.

Used unicode again and got that again. I did change the code to look through 20 and only that. Works with no unicode though. Also is it possible to add a progress bar (or just the %) with the download speed somewhere? (Sorry if it looks like I'm asking too much but I'm just suggesting additional features that might be useful in the future )

I may have time tonight to look at the problem.

I don't mind the requests at all. I'll look more into it. It may help me when i start the GUI for Java. But I've gotta get school work finished first.

I've fixed the problem. I wasn't using a function incorrectly. I'll look into the progress bar soon and download speeds soon.

I was trying to make a GUI and I came across a nice application to do so Glade 3. Why not try using that? I'm actually working on one myself at the moment.

I've been looking at the GUI builder in NetBeans. I'm currently working on a semester long group project for my class and learned how to use it properly. I already have a program running just like this one in Java, but I've been busy with so many things.

I will take a look at this though. It looks quite interesting. Thanks

If you've already got working code in python, I suggest that you take a look at pyqt or pyside.

I know getting it to work in a GUI isn't hard, but i want to make it so that nobody will need to download anything before using it.
Virtually everybody has Java and that's why i'm trying to work more toward it.
Python is great, but people need to get the right stuff for it to run. Unless there's something i'm missing...

Are you using the most current version? I've had problems with MediaFire in the past that caused this issue. I've switched over to pastebin now.
I assume you're using the correct version of python for the code or else it would have given a different error.

Besides those two, I should look into what Howl said earlier and just make it into an exe and just submit the source code.

I'm using the most current version of both your script and python ^,^`
And yeah, I agree with that

At the moment, there isn't. I'm planning on making the GUI version probably some time in December and that will have several options such as downloading ranked or approved maps.

I've gotta finish my college project before playing with anything else. This thing is worth 70% of my grade so it's just a little more important.

Ok, no problem! I can wait until then. After all this is just clicking some circles to pass the time.

Done with classes! I'm fairly certain i passed, but can't be sure until grades are posted.
I've learned quite a bit with NetBeans over the past couple weeks so i'm certain i can get this working.
I have just a plain command window java version working right now. Works almost exactly like the python version.
However i can add options to a GUI program much easier than command window versions.

Here's what i have as for the options:
Download location (where it's saving the files)
Song title format (ASCII or Unicode)
Illegal characters replaced with (unicode equivalent or underscore or maybe a custom one)
(＼／：＂＊？＜＞｜ or _)
Number of pages checked (10 songs per page; no upper limit)
Number of threads (simultaneous downloads; up to 4)
Status filter (ranked, approved, unranked, etc.)
Genre filter (video games, anime, rock, etc.; genre set for songs may not be accurate)
Mode filter (Standard, taiko, CTB, mania)
Search popular songs (I would have to add filters manually)

I remember seeing updating songs as one request. I'm fairly certain i can get this to work. Check download folder for already downloaded songs and search for their numbers or somethin like that.
One option that i've been thinking of is download from a certain date. Sometimes i don't have my downloader running after a reset or someting, so i check for the date the last song was created and start downloading from that date.

Let me know if there are any other options you'd like added.

I've just tested both versions 2.7 ans 3.4. They are both working on my end.
What i think happened was that the site bloodcat.com was down for a little bit.
It happens from time to time. Go ahead and try again and let me know if it's working.
