Playlist Undo (v1.11 - 23/10/2013)

[DrO]

Playlist Undo v0.1.0

• Initial version of the plugin which adds the ability to undo a number of actions made to the current playlist in Winamp
• Requires Winamp v5.0+ to get full functionality
• Adds an 'Alt+Z' and playlist editor right click menu to allow for quick access
• Basic undo queue viewer to see what is in the undo queue(since not all possible modification actions to the playlist are handled)
• Supports most full playlist removal actions, delete actions in the playlist editor, modification to the playlist when Winamp is initially loaded (e.g. Winamp is made to open with a 'Play in Winamp' command)

Egg seems to be happy with this and considering it's so early on in its development life-cycle it's already looking good. My aim is to eventually add in support for more playlist modification actions but i'm also looking to add in playlist change locking features to this plugin (ref this) since it fits in with the idea of controlling the playlist editor actions i think Enjoy (and thank Egg for pestering for the last 2 years about getting this one done... at last, hehe)

Latest version: v1.11

"Egg seems to be happy with this"

That's an understatement.
This plugin fulfils my 5-year+ long wish for Playlist Undo functionality. Awesome! :-)

[billyvnilly]

get the f*** out!

[JonnyMac]

Dammit

Why do you release your new plug-ins when I am at work? Now I have to wait all day until I can go home and try it out.

[fisher819]

you rule drO

[Squadman]

This rocks.

I've been hoping you'd do something like this, for SOOOO long.

Could you possibly make it possbile to make CTRL+Z a the basic undo key, because using ALT+Z is weird.

[DrO]

JonnyMac: hehe

billyvnilly: yes, both Egg and i need to get out more

Squadman: Ctrl+Z is already taken for 'move to start of list' (is the same as a ctrl+click on the previous button)

@ billy
You should know by now that mods don't have a life.

@ DrO
Very nice!

Now, is there anything you can do about Egg's other wish?....
Different icons and file descriptions for associated file types.

[d3x7r0]

Hum... You can't undo adding a file (enquee) from the playlist?

Oh well it's better than nothing, took quite some time for this one to come out but it's great to see it arround

[DrO]

d3x7r0: enqueue isn't currently supported since that will be part of the next stage of development (i went for the easy bits first) and you can't expect everything for an initial version

JonnyMac: heh, i thought the extended playlist plugin was the main other one he wanted

-daz

[billyvnilly]

It was lost on both of you,lol. Its an expression of amazement. impressive beta.

well....both the extended playlist and file icons sound nice...

ohh, happy forum bday.... great. its the terrible two's.

[JonnyMac]

@ DrO
Maybe the icon thing is third on his list.

DJ Egg, care to share some light on this????

@ billy

So I was lost. Whatever.

[DJ Egg]

I guess plex is #2 on the list, seeing as there's known workarounds for different icons/descriptions, heh. There's plenty of others in the wishlist, though Playlist Undo was always #1 for me.

[fisher819]

let's hope we can see some improvments on plex.

[DrO]

fisher: hopefully since i spent most of yesterday updating the code base and trying to make it useable again (at least it now saves settings and will parse the playlist(s) again without crashing )

-daz

[d3x7r0]

so DrO any updates to this?

[DrO]

Playlist Undo v0.1.2

• Fixed the creation of the temp backup playlists to now work correctly in all cases and to be unique to prevent potential issues

get v0.1.2

Functionally this is the same as 0.1.0 but fixes a glaring issue with the temp files that the plugin uses when alterations are made where the api call used was incorrectly handled causing .tmp files to be incorrectly created and could allow duplication of filenames which could cause undo list corruption.

-daz

[d3x7r0]

Here they are, just installed it

I can't imagine living without it now

[DrO]

just make sure to clean out the contents of the gen_undo folder (since i bet there's some unwanted files in there) and hopefully this new build should never allow that to happen again

now which plugin will be the first to have an '06 update..

-daz

[DrO]

Playlist Undo v0.2.0

• Added resizing to the queue list dialog and also the time the undoable actions happened at
• Added configurable option to allow the undo list to be preserved after Winamp has been closed
• Added right click options to the undo list dialog to allow for quick clearing of the undo queue and to allow the selected entry to be saved to another playlist (may be useful)
• Altered the backup playlists to be set to read-only (incase someone tries to overwrite them)
• Added in two new event handlers which should catch most enqueue / external add / ml enqueue actions
• Slight code tweaks/clean ups

get v0.2.0

Apart from the newly added methods, there is a slight change in the way that the plugin handles it's detections to now include adding to an empty playlist since it was missing some valid enqueues from the ml with the existing check.

Also when ml play/enqueues are done (which uses the WM_WA_IPC version of IPC_ENQUEUEFILE), there is likely to be multiple undo actions added depending on the size of the undo action. This will be the case until i code up a smarter way to handle mutliple fast playlist additions but other than a few extra alt+z's it's not a major issue for the time being

[lexel]

Great, thx a lot!

[alexbarb]

Great plugin! Big thnx!!!

But from where it takes the time? Is it GMT? My time in windows is GMT+3 and it disagrees with the time in the Undo log

[DrO]

Playlist Undo v0.2.1a

• Made it happy to work with DEP enabled
• Fixed to use local time and not system time (UTC)

get v0.2.1a

alexbarb: How's that for bug fix speed

-daz

[alexbarb]

not bad

[airmind]

First of all, I loved this plugin. You have no idea how much time have I lost by not having a undo menu.
And now that I have I would like to help you out. Just a problem that I noticed. I'm on Windows XP SP2, and if it helps I have brazilian regional settings (but the Windows XP itself is in English).
And this picture pretty much explains the problem:



I've done a few extra testing and the situation is that those characters appears in that order and after that the date is blank, but only for dragging operations.
Oh, and, do you need the miliseconds? It looks a little too complicated with all that numbers when all you want is to know is how old is that change.

[drewmacphee]

Hey..

I noticed that if you do an undo while a song is playing.. it thinks that the currently playing song is the first one in the list.. even if it's not.

example

first song
second song <-- currently playing song <-- currently highlighted song
third song
fourth song

first song
second song <-- currently playing song <-- currently highlighted song
fourth song
third song <-- oops moved this song by mistake


first song <-- currently highlighted song
second song <-- currently playing song
third song <-- undo moves this song back
fourth song

so at the end of second song, second song plays again when third song should play.

Great Plugin though.. keep up the good work.

[Rijk]

Can you make it able to undo an explorer click? Sometimes, when I'm dragging files (I do that a lot) I accidentally click one, and Winamp starts playing and I lose my playlist. I thought this was the solution, but at the moment this plugin can only undo Media Library actions.

Is it possible to put this in it?

Great plugin btw!

[DrO]

it should be handling accidental explorer clicks since that uses the same message actions as media library and other internal enqueue actions. if i ever get the time to do coding i could have a check over of it

-daz

[Koopa]

DrO, is it possible to add an option, wich deletes old playlists in the gen_undo folder after x days?

[d3x7r0]

That would be great, my winamp is starting to get slower startup times and it looks like deleting the gen_undo info brings them down... I might be wrong in my assumption though...

[DrO]

i agree with the request (and i remember Egg pestering me about it). and yes, if the number of undo actions becomes too large then startup times will slow down (which i need to optimise in a few ways along with the limiting option).

-daz

[DrO]

Playlist Undo v0.4.0

• Reworked the internal cache handling so it will save out only what's needed to winamp.ini and better protects itself against unexpected issues ie someone tampering with the backups
• Improved the clear queue code so that it'll remove all files in the queue and those that are left over and to full clear anything from winamp.ini
• Removed the millisecond display from the time of the queue event in the undo queue viewer
• Added in ability to limit the number of undo queue events that are held by the plugin
• Added a clear undo queue and backup folder option to the plugin's preferences (same as the clear undo option on the undo queue viewer but is accessible when there's no undo queue
• Improved the handling of an internal message used on startup to work better on Win9x systems
• Added the option to save the current state of the undo queue out to winamp.ini on all undo queue changes (default off since it may cause some slow downs but will handle Winamp crashes correctly so the queue list would be preserved)
• Added in the ability to block a number of user actions on the playlist editor (left-click,right-click,double-click(though should still allow winshade to be activated),keyboard and mousewheel (*)

get v0.4.0

has been a while since the last official build but here's a new one with some noticeable changes and improvements to it. i'll post a full changelog in the morning but i need to get some sleep in. also i've not had a chance to verify the issues reported by airmind and drewmacphee (i hope things are fixed now but will double check again). the limit by x days needs a bit more work to get it implemented but i hope that one of the new features will help enough for the time being

(*) This is complete for classic skins however due to the way in which modern skins work, there's still some more work which needs to be done with this feature since the modern skin frame is still effectively active for a number of the actions (which may be a pain to implement)

-daz

[Koopa]

Nice, you've integrated the ability to delete the gen_undo folder and it's now possible to limit the number of the undo actions.

I'm glad to see these improvements. I'll test the plugin within the next few days.

[DrO]

changelog up now

yeah, this new version should be a lot better on handling of the undo queue (especially with the new save on the fly option incase of Winamp crashing)

-daz

[priestlyboy]

lol, btw it's may not june...

[DrO]

dunno what you mean

-daz

[lexel]

I cannot DL the v0.4.0 file.

[DrO]

-daz

[lexel]

Thx, the attachment works well!

[Koopa]

can't see why it wouldn't work since i can get to the file fine here from work.

The download just works fine.
