In the new launcher I've been trying to install single player commands and world edit 1.2.5, but when I try to launch the game, every single time it deletes the modified version jar, and downloads a new one. It won't let me mod. I have the same problem with MultiMC, and basically every other launcher.

'bout 4 days to a week and a half if I recall correctly.
It should be alright 'round 4 days. Was quite the build that came around with the new blocks and such.
Websites updating and such too. It'll be alright though. Have you went to see if the old launcher does what you need it to?

I can't find the old one anywhere, and every other launcher does the same thing. MultiMC, ATlauncher, Technic, FTB, Curse...

Well if it aint down they must be doin' somethin' under the hood then.
I'd give it some time.
I'm enjoying each day til' my new graphics card arrives. Old card went kaput or somethin', I'm on vga and can't get the old or the new launcher to launch(play the game).
So that is a change right there. I know when I was back in shreveport, I was able to update my mod with a vga monitor no problem and get the game to run with 20fps.
Somethings going on though, aint no tellin'.
By editing the json they mean doing what is shown here; this has been an issue for over a year now, and even befor ethne you had to rename (and still do) the jar, folder, json and the "id" inside the json:
MCL-4334 Minecraft gets reinstalled everytime you launch it - see the attachment; you want to make it look like the left side. You do not need to delete any other "downloads" just the one that refers to the client jar. Be careful that the braces and commas match up or the launcher will complain that it is corrupt, or just not recognize it.
Otherwise follow the instructions given here - except DO NOT just use Windows to open the jar as a zip; many versions have certain class files which are illegal Windows filenames and will be renamed or not copied (apparently, the version they used as an example does not, but this caught me when I first tried modding back in 1.5.1): http://minecraft.gamepedia.com/Mods/Installing_mods#Installation_for_the_1.6_launcher
I have not had any issues with this; the launcher does complain that it can't get the hash for my modded jar but it runs the game (note the error about legacy.json, which gets redownloaded every time I play for some reason because it thinks the hash is wrong (missing?), which is what the launcher normally does if a file doesn't match it):
12:25:32 launcher Preparing to launch minecraft client for TMCWv4
12:25:32 launcher Local file C:/Users\\AppData\Roaming\.minecraft\assets\indexes/legacy.json has wrong SHA-1 hash, expected but was c0fd82e8ce9fbc93119e40d96d5a4e62cfa3f729

For some odd reason though this does not seem to work for everybody, even when I sent them a modified json that worked on my computer, which just has a normal Minecraft installation using the default launcher:
Also, I tested your JSON file on both the new and current(the one installed when you download Mojang's installer) launcher(both using latest version available), and it didn't work on either of them. It would bring up the error about the SHA-1 hashes being missing. However, it worked on an older version of the current launcher, meaning that something in the code of the launchers have changed.
Note that the new launcher did rewrite my custom json when I upgraded because it thought that it had an incorrect hash (which isn't even in the file), the only difference I can see is that it compressed everything into one line, which it is also apparently doing with vanilla jsons.
Also, custom launchers like Magic Launcher add jar mods to the game when it is launched, similar to Forge mods - you are supposed to choose which mods to use from a menu:
the Magic Launcher is a new Minecraft launcher which can load mods dynamically without changing or patching the minecraft.jar.
Actually, you can even do this with the vanilla launcher by adding the mods as libraries in the json file (change the extensions to jar), similar to what is shown here (I did this to install my own non-Forge mods and Optifine when I used Forge, though Forge still complained that the jar had been modified): http://minecraft.gamepedia.com/Mods/Installing_OptiForge/Forge_Installer
Wow, this is one of the more detailed and helpful comments on this subject that I've found. Maybe you can help me. I'm trying to install a .class only mod (no forge, liteloader, jar version etc) for 1.7.10, and I can't seem to find any combination of messing around that will make the mod work. I've tried deleting lots of things in the .json file, specific things, and all manner of related stuff but nothing works, it simply redownloads itself every time. I also found a copy of the archived 1.6 launcher, and that didn't work either, its still redownloads everything. I tried magic launcher, but I don't know how to get it to recognize my mod since its just a class mod. I've been at this for ages, and at this point I'm very close to giving up and saying its simple not possible to use .class mods on minecraft anymore. I've used some other simple mods (light level overlay, which is a forgemod, and chunkborders, which is a .litemod) but this one doesn't work.
I wouldn't be trying to hard except that using this mod is kinda essential to what I'm doing. I'm making an Iron Golem Farm and its a village marker that shows where villages has been formed. Without it, there is no way to troubleshoot the farm.
I guess I need help:
Knowing exactly what to delete in the .json file. And I am having the "Everything is compressed to one line" problem so its incredibly difficult to tell what I should delete.
How to configure my mod as something that Magic Launcher can recognize.
