Port CHDK file browser (file_man.mo)

[minimimi]

made a repo
https://bitbucket.org/minimimi/magic-lantern-filer-alex-based

and Found reason for number issue . Solved it now.
Next, I will think about how to implement multiple-selection and "file operation status window".

[1%]

Ok, I'll keep updating.

[g3gg0]

ah sorry, i already checked in your new source code.
just wanted to write that here then i saw you forked on bitbucket

btw the numbers come from a missing
    e->menu_entry.priv = NULL;
after every menu entry.

i also added functions so that registering custom file types by other modules is possible.
so we can playback raw from within the filemanager.

[a1ex]

I wouldn't recommend deleting the priv entry, since it was designed to identify the item. Just make sure you call the default update_action if you use a custom update function.

For actions, please use TYPE_ACTION.

Progress updates can be displayed from update_status (displayed at the bottom).

ScanDir is not thread safe, it needs a semaphore.

[minimimi]

G3gg0:
Thanks , I already used alex method(Used TYPE_ACTION).But I'm override menu_entry->update myself.It was problem. Solved it now.
And , I'm also thinking RAW playback from filer.
See here.

Code Select Expand

enum _FILER_OP {
    FILE_OP_NONE,
    FILE_OP_COPY,
    FILE_OP_MOVE,
    FILE_OP_PREVIEW
};


So I want to know, how to know raw_rac.mo is already loaded, and how to call funcstion in anothers.
If you have a patch file, share it please,

Alex:
Thanks suggestions for making Progress. Will try it.

ScanDir things. need a "menu_sem" ? . So I added functions in menu.c in previous codes src/filer.c version.
Need to add, GetSemWrapper()/ReleaseSemWrapper() in menu.c?
Is this better way? How do you think?

[minimimi]

You already have write permission on my repo. Because I'm used same permission with main repo.

[a1ex]

ScanDir things. need a "menu_sem" ?

menu_add already has semaphores, so I think it should be alright. ScanDir was manipulating a linked list, so I've added the scandir_sem just in case. The only situation when things could have gone wrong was if you pressed some key exactly when a copy/move operation finished.

G3gg0 and Alex

Thank you for your merge/implove/brush up.
It's perfect for me. I'm using 64gig SD and 32gig CF. So I wanted to move RAW to SD.

Maybe here and
http://www.magiclantern.fm/forum/index.php?topic=5936.new#new
are close-able.

Multiple file selection is future TODO...I have no idea to make multiple file selection now...

[minimimi]

OK!!!!
I found answer for multiple file selection!!!!!
Soon will open new repo.
Already , almost codes are working. Yay, wait a moment

[1%]

EOSM now have to touch screen to go up

[minimimi]

https://bitbucket.org/minimimi/magic-lantern-filer-multiselect

basic functions are working. push file twice.

now debugging
-already registerd check when we push copy menu.
-cancel copy operation when we un-select all files

1% ,
we need "../" ?? or need ifdef for EOSM?

[1%]

Q on eos M is 1 finger tap. No q button, only set. I don't know if you "need" it. I can use it either way.

[aaphotog]

......

[minimimi]

1%
I mean , use ifdef for :
-disable Q
-show "../"
Then you can use file manager with cursol keys. Is this a correct understanding?

I think almost fine on my multiple select codes. please check it except M(sorry.

[a1ex]

Modules were designed to be portable, so... better just add it back?

[minimimi]

I got it. Never use ifdefs in modules.
Then, how do you think about M 1%?

[1%]

Either leave as is or add ../ back. Its only an issue where it will be confusing to people.

* Although probably only 2 people with eos M care.

[minimimi]

Alex:
Oh! important point is conflicted.

Are you already disabled "Q" ??

[a1ex]

?! Q works fine here, it goes back by default (unless you override it when creating menu entries).

[minimimi]

https://bitbucket.org/minimimi/magic-lantern-filer-multiselect/compare/hudson/magic-lantern:unified..unified#chg-modules/file_man/file_man.c

see here.
If you have no problem, enbale selectQ plz for multiple file selection.

Modified
Alex. sorry for confusing. I just understood you are not disable Q everyware. So I can solve myself.

[a1ex]

File selection works very well, you can even select files from multiple folders and copy them to the same destination dir, very nice!

I've changed the buttons as follows:
- PLAY selects individual files
- menu entry for selecting all files with the same extension (e.g. if you shoot raw+jpeg and you want to delete all jpegs)

We need to be very careful with background tasks and exclusive access to certain data structures; for example, it was trivial to break the copy operation just by navigating to some other directory while copying (!)

[minimimi]

Thanks your daily cooperation and polish it up.
I think we need to add some more miner chagens. When I make it, I will make a pull req.

-we need skip , when src & dst files are idential
-disable automatic power save (However we can't use half-push tric here. and we don't wanna change NVRAM value...)

[a1ex]

For powersave I would add only a warning in menu.

[minimimi]

I see. It's one of solution for current our knowlege.
And , pushed small pathces for "src&dst files are idential " and "cleanup memory when unloading".
Please review it.

Um, on my 60d the file browser is extremely slow when I try to browse a directory with a lot of files (like 1000) - is that just me, is it being worked on, or is this just the way it is?
