File Browser upgrade

[grch87]

Hi,
as my ESP Tonuino is finished, I got the request from friends, if I can build them as well one. However, they don't feel confident enough to deal with an FTP client to upload the files.
Therefore I decided to extend the current file browser with the possibility to upload files and add some basic functionalities:

• Create Folder
• Delete File/Folder (nested)
• Rename File/Folder
• Refresh
• PlayAudio

I used the current solution with jstree, but had to change the way how the data of the filesystem is synchronized between the ESP and the client.
I tried to use a more dynamic approach. Instead of one big json file, containing all files and folders of the filesystem, the client is requesting the content of a folder from the ESP, when the folder is entered or something got changed in the folder (e.g. upload, deletion...).

I perfomed the commit under:
grch87@5ba8fb4

And here a picture how it looks like:

Maybe this is as well a nice feature for the master branch.

I just faced one issue. I store the html file on the sdcard which is working fine. When I use the processHtml script to integrate the html code into the source code the html page is not properly shown on the client side. Any idea? Maybe the page got too big?

Wow, cool! Will have a look at it.
Regarding the problem... rust a rough guess: Have to been commenting out stuff using //? Problem is that the whole html-file is finally a one-liner. So commenting out can lead to commenting out all subsequent stuff :-) And yes, I ran into this problem, hehe.

I got it running using send_p(), but it's to fully functional. So yes, maybe it's way to big now.
However, when serving via SD, you also need the template-processor:
request->send(FSystem, "/index.html", String(), false, templateProcessor);

Tested the upload-function. Is around 140 kB/s. Way slower than FTP, but it's working anyway :-)

Cherry-picked your commit into a new feature-branch: https://github.com/biologist79/Tonuino-ESP32-I2S/tree/feature_filebrowser

Moin,
I fixed the problem, that the website couldn't be loaded from the ROM:

Reason was that some semicolons were missing. This causes of course problems when everything is in one line :D

Hi,
I did an update in the upload part. I moved the writing of the data onto the SD card to another task. So aquisition of the data via the network and SD storage is now done in parallel, which increases the speed by 50% (280-360kB/s jitters quite a lot). I know it is increasing the complexity, but for the speed increase it is worth I think.
My commit is here:

There was as well a bug. The sleep timer is not reseted during the upload, so the tonuino can go into sleep. This is as well now fixed with this commit.

Cheers

Well done, integrated the commit yesterday. But still had an issue when uploading large files as Tonuino went to sleep after the period configured.
