# cwtest Testing and Development Application for libcw.
`cwtest` is a command line interface to [`libcw`](https://gitea.currawongproject.org/cml/libcw).
It is primarily used to as a minimal interface to develop and test `libcw` subsystems.
See the [Currawong audio processing language and environment `caw`](https://gitea.currawongproject.org/cml/caw)
for an example of a complete application based on [`libcw`](https://gitea.currawongproject.org/cml/libcw).
`cwtest` command line:
```
cwtest <file.cfg> <label>
```
Where `<file.cfg>` refers to a libcw configuration file file with the form:
```
{
test: {
`program_0`: {
a:1
b:"hello"
},
`program_1`: {
arg0:["abc","def"]
b:{ a:73, z:[19] }
}
}
```
`<label>` refers to a specific set of named parameters
(e.g. `program_0`,`program_1`) which are associated with a library
function. See `main.cpp` `mode_array[]` for the mapping of labels to
functions.
The goal of `cwtest` is to be able to easily exercise `libcw`
functions, or build simple utilities based on them, with a flexible
sets of parameters. The primary parameter file used for the programs
and tests below is `src/cwtest/cfg/main.cfg`.
Below is a list of named parameter sets from `src/cwtest/cfg/main.cfg`.
The `label` field refers to the name given to a parameter set
in the `main.cfg` and is also used to select the associated program
from the command line utility. Searching for the label in 'main.cfg'
will show the complete set of editable parameters available for a given
test function.
The `Source File` and `Function` field gives the source code
location for the function associated with each parameter set.

## Run Unit Tests:
These test are run by the libcw testing framework in cwTest.h/cpp.
The configuraton for the unit tests is in `src/cwtest/src/cfg/test/main.cfg`.
1. Add a new test:
- Create a function like this: rc_t my_test_func(const test_args_t& args);
- Add the module name, function pair to the `_test_map[]` in cwTest.cpp.
- Add an entry to the test parameters cfg. below.
+ Name the test case (e.g. `test_0`) and give the test parameters.
+ On the call to my_test_func() the args.module_args is set to the 'module_args' dictionary defined in the cfg.
+ Likewise args.test_args is set to the 'test_args' dictionary referenced by the test name label 'e.g. test_0:{ my_arg:1 }'.
- Run the test like this: `cwtest test/main.cfg test /my_module test_0 echo` to see the results of the test run.
The results of this run will be written into `/cur/my_test/test_0/log.txt`
- Once the results have been validated copy the output from 'cur' to the `/ref/my_test/test_0/log.txt.`
- Verify that the test passes: `cwtest test/main.cfg test /my_module test_0 compare`
2. The test spec. is recursive. Modules can be listed inside of modules. (e.g. 'lex' and 'flow').
3. If a module spec. does not have an embedded
'module' or 'module_args' then the cases may
be listed without a 'cases' label.
(e.g. 'filesys','object', 'vop')
4. Command line args:
Parameter | Description
----------------|------------------------------------------------------------------
<module_path> | 'all' (required) The module path always begins with a '/'.
<test_label> | 'all' (required)
'gen_report' | Print modulue/test label.
'compare' | Run compare pass.
'echo' | Print the generated test output to the console.
'args' | All command line args after 'args' are passed to the tests.
5. Example command lines:
```
cwtest ~/src/cwtest/src/cwtest/cfg/test/main.cfg test /lex test_0 gen
cwtest ~/src/cwtest/src/cwtest/cfg/test/main.cfg test /flow test_0 compare
```

# 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.
