Status Lines in logfile

[Eve00000]

Feature Description

Hello, Is it possible to add concrete (readable) statuslines for plateractions in the logiles? Type of Date/Timestamp - Deck/Sampler[NR] - Action (Loaded/Start Play/Stop Play/Eject) - Track (Artist/Title) Thank you

hey there. Lets look at this from a usecase perspektive. From what I could gather from your various forum posts and comments on issues/PRs is that you want to send the name of the currently playing/loaded song of deck to your hardware and you're currently working around shortcomings within mixxx by inspecting the log. Wouldn't you agree that it would be better to fix the shortcomings within mixxx instead of requesting features that would hack around it?

The functionality you want (accessing the players from the javascript mapping engine) is already partially implemented for QML (see mixxx::qml::QmlPlayerManagerProxy). All that's really needed to do is figure out how to make the QmlPlayerManagerProxy accessible from plain Javascript as well. Would you agree that this is suits your needs better?

I assume you want to use it for displaying the track data on your Denon player https://mixxx.discourse.group/t/explanation-logfiles-sending-tracktitle-to-controller-lcd-need-help/28986/2

I think parsing the log is a okayish but brittle hack, a more robust / easier solution would be to write the state changes to individual files (per deck). Please check #3483. That PR is huge and does a lot more than writing files, but it contains the building blocks for watching play/pause changes and writing per-deck files, incl. preferences options where to put those files.

Hi, thank you for answering. First of all: off course it would be better to transmit the data directly from within mixxx. I'm not so familiar with github and pull requests etc. Could you please explane what happens when later a new version 'main' comes out, does that include all the work people did on pull requests or is all the work gone... FYI I had already another workaround with screenshot -> define areas -> ocr -> combine ocr text with variables to new javascript file. For what I know javascript is and will always be blocked for accessing local files on pc, this for security reasons. That is why parsing to javascript / including local files is impossible. I think there are 2 solutions possible: A: using an ' object'-type. For changes in my itynes-library I use the itunes-object. B: using a simple webserver. I'm not sure but I think this will always cause installation problems.

So please can you explane me first how working with pull request really works? Thank you

main is the development branch. PRs are targeting a certain branch (version) and the new feature / bugfix will be available as soon as that version has been released. No work is gone, not sure what you mean.

Sounds like a great hack : p

Maybe lets start from the beginning. What controller are you using? Is there already a mapping in mixxx? How do you communicate with it (midi&sysex)?

[evelynnev]

Is there a way to communicate directly? fi chat or so? I have a denon hc4500, I've found a midi file on the board here from 10 years old that I'm tweaking

Oh i downloaded github again (after a long time) and it recognized my old username :-) I downloadad the PR as you call it, I can't find the architecture-map in it do you have a map?

[evelynnev]

this does the trick:

for /f "delims=" %%a in (title1.txt) do set "line3b=%%a"&goto :stop :stop

-> midi.js file has new values for vars Artist1 Artist2 Title1 Title2 ;-) -> updated in mixxx on-the-fly and displayed directly -> script is run every 5 or 10 sec :-)

I have been reading a lot, looking at code .... How can I compile this version to try it? (I am not good in github stuff, sorry)

yes, you're welcome to open a new topic at https://mixxx.zulipchat.com/#narrow/stream/113295-controller-mapping

I downloadad the PR as you call it, I can't find the architecture-map in it do you have a map?

I don't have a mapping, but you're welcome to add one. If you want to add the feature you want (reading out data from the decks from the JS), you'll need to do a little C++ coding though. I already gave you the appropriate pointers above (with the QMLPlayerManagerProxy). I encourage you to check out the Controller Mapping docs and the developer docs. Both should help you to get started developing and submitting this feature.
