libcw Testing and Development App

GDB Setup:

set env LD_LIBRARY_PATH /home/kevin/src/libcm/build/linux/debug/lib
r ~/src/cwtest/src/cwtest/cfg/main.cfg mtx

// if problems occur with gdb hanging while download debuginfo 
sudo dnf upgrade --enablerepo=*-debuginfo "*-debuginfo"   # update all debuginfo files

r ~/src/cwtest/src/cwtest/cfg/video/video.cfg preset_sel  record_fn m302-325 beg_play_loc 9187 end_play_loc 10109
r ~/src/cwtest/src/cwtest/cfg/video/video.cfg preset_sel  record_fn m350-458 beg_play_loc 12431 end_play_loc 14726
r ~/src/cwtest/src/cwtest/cfg/video/video.cfg preset_sel  record_fn m1_283 beg_play_loc 0 end_play_loc 8452

r ~/src/cwtest/src/cwtest/cfg/gutim_full/gutim.cfg preset_sel  record_fn m1_458 beg_play_loc 327 end_play_loc 396

Valgrind setup

export LD_LIBRARY_PATH=~/src/libcm/build/linux/debug/lib
valgrind --leak-check=yes --log-file=vg0.txt ./cwtest  ~/src/cwtest/src/cwtest/cfg/main.cfg mtx

Installation

Dependencies:

• libwebsockets-devel
• fftw-devel
• libcm: lapack-devel

•   atlas-devel
  

#Design Questions:

How should errors be presented to the user? developer?

#To Do:

All callbacks should return meaningful result codes.

UI Properties

name            - becomes the HTML id for this element
appId             application id for this element
title             label or title for this element
className         Base class name for this element. All elements have a built-in default class name.
addClassName      Add this class name to the class name.
clickable         This elemnt will send a 'click' msg when clicked.
enable            This element is enabled
visible           This element is visible.

Preset Select

• If the the parsing of the main cfg file fails the app crashes in main.cpp with a double free.
• play on preset letter select
• allow the network to be reloaded without restarting the program
• create an interactive spec-dist panel to experiment with presets

REVIEW:

• gain problem

• was it really the transition bug and not a gain bug?
• FFT normalization
• Float/Int conversion on ALSA output
• create a metering object to examine signal at various places in network
• add compressor/limiter like in cm based network

DONE:

• save preset check box state.

• verify that all fragments are saved and restored

• UI: remove 'Filename' entry box.

• flow proc: gain, audio channel split map, audio channel merge map, fixed delay

• Fix CPU usage: work around for serial port server.

• App: apply wet/dry and gain when new presets are loaded.

• App: add 'Note' to fragment

• App: add per fragment play control with begin/end locations

• UI: reorganinze top panel layout

• App: Add a status box to report errors and warnings to the user.

• App: Send log output to "Log" UI.

• App: When a invalid value is entered (thereby disabling a control) a message should be written to the status box.

• App: Add ranges to numeric controls.

• App: What happens when an invalid value is entered in a GUI control?

• App: interactive wet in gain, wet out gain, dry gain, piano midi enable, sampler midi enable, sampler delay

• App: interactive print network

• App: automatically load on start

• flow: Allow setting a specific variable value from a network preset

• preset_sel: The sampler requires a different velocity map than the piano. The piano was scaled down but now the sampler is too quiet.

• preset_set: deleting a fragment does not automatically fill in the missing location space.

• preset_sel: backup to numbered file on save

• preset_sel: Velocity of the individual notes of chords should be scaled to such that their sum matches the dynamic value.

• libcw: Make IO sub-systems optionally synchronous

• UI: clear UI when the app disconnects.

• UI: Add an error indicator and API for each control (e.g. border set to red)

• UI: Add the ability to order child lists via the 'order' attribute.

• UI: Add API to delete a UI element

• UI: add HTML class and name assignments to row/col div's. (See 'name' and 'addClassName' attribute.)

• UI: add min/max/incr/decpl attributes to numeric variables (See uiSetNumbRange.)

• PresetSel: Select and highlight a fragment.

• PresetSel: + test adding,deleting, saving and restoring fragment records

• Enable 'Delete' button when a fragment is selected.
