## Getting Started



### Running an application



Clone one of the above [applications](#Applications) and follow the instructions there to run them.



### Prerequisites



#### Homebrew



[Homebrew](https://brew.sh/) is a useful package manager for Mac OS X, to install it follow the

instructions on their homepage.



#### Python



Most of the repositories require a Python version of *at least 3.8 and at most 3.10*.

For the provided build tooling the `python` and `pip` command must be linked to an

appropriate version, You can check the version and used installation with the



    python --version

    which python



commands. One option to manage Python versions is to use [pyenv](https://github.com/pyenv/pyenv).

Note, however, that `pyenv` doesn't work well together with anaconda. To detect if you

are using anaconda use the command above.

On OS X you can alternatively you install specific Python version using homebrew by installing



    brew install python@3.10



and adding it to your PATH variable, like



    export PATH="$(brew --prefix)/opt/python@3.10/libexec/bin:$PATH"



in `~/.zshrc` (see also their [their documentation](https://docs.brew.sh/Homebrew-and-Python)).



*Note* that using an alias for the `python` command in the shell configuration script does not

work as aliases are eventually not expanded if the shell is not in interactive mode.



##### Anaconda



If you are using anaconda the installation of some of the dependencies with pip can cause

issues. For this reason we recommend *not* to use anaconda to build and run the Leolanii

platform. As mentioned above, anaconda does not work well together with _pyenv_ as both use

the same mechanism to intercept the system PATH. If you are usually using anaconda to manage your

Python version, one option is to set the system Python installation to a version compatible with

Leolani and deactivate anaconda for the time working with Leolani. Note that anaconda typically

activates the _base_ environment by default when starting an interactive shell.



To set the system Python version with homebrew on Max OS X run



    brew install python@3.10



and follow the instructions in the output messages to prepend the PATH variable in your

`~/.zshrc` file and add your modifications _before_ the anaconda setup in `~/.zshrc`.



#### make



To build the application, `make` is used.



On OS X it is recommended to upgrade `make`. Since OS X doesn't use standard GNU

utils due their restrictive licence, default `make` on OS X is way outdated.



One option is to use homebrew:



    brew install make



and add the installed `gmake` command by adding



    PATH="$(brew --prefix)/opt/make/libexec/gnubin:$PATH"



to your `~/.zshrc`



#### Docker



[Docker](https://www.docker.com/) is a tool to run our applications or components in a

containerized runtime environment. To install it follow the instructions on their homepage

or use [Homebrew](https://formulae.brew.sh/cask/docker). *Note* that you need to use the

`--cask` option with Homebrew!



#### Java



To check if Java is installed on your system you can run



    java --version



in the command line. If this does not work, install Java, e.g. with



    brew install openjdk



#### Graph DB



Some components use GraphDB, to install it register on their

[homepage](https://www.ontotext.com/products/graphdb/download) and follow the provided instructions.



#### C compiler



Some dependencies require a C compiler to be installed. On Mac OS X you may need to install



        sudo xcode-select —install



If you encounter error messages regarding an invalid version of clang, you may need to reinstall

by first running



        sudo rm -rf /Library/Developer/CommandLineTools



followed by the installation command above.



#### Rust compiler



Some dependencies require a Rust compiler to be installed, follow the instructions on their

[homepage](https://www.rust-lang.org/tools/install) to install it.



#### System libraries



##### Audio



Python audio libraries may need portaudio to be installed, on Mac OS X you can use

[homebrew](https://formulae.brew.sh/formula/portaudio#default) to install it. To

figure out specific instructions regarding your hardware a simple internet search should

find you the answers.



Also *libsndfile* and *ffmpeg*  may need to be installed on your system.



Mac OS X the above can be installed with homebrew:



    brew install portaudio libsndfile ffmpeg



It is possible though that homebrew does not link the *libsndfile* properly, in this case follow

the instructions in this [stackoverflow](https://stackoverflow.com/questions/67973223/cannot-import-soundfile-mac) post

and pay attention to the output of homebrew. A likely fix is to add the following line to your

shell initialization script (`~/.zshrc`):



    export DYLD_LIBRARY_PATH="/opt/homebrew/lib:$DYLD_LIBRARY_PATH"



##### Video



Pillow eventually needs additional system libraries to be installed, check the *External Libraries* section in their

[installation instructions](https://pillow.readthedocs.io/en/stable/installation/building-from-source.html#external-libraries)

if you run into errors related to Pillow.



## Development



To work on the development of a specific [application](#applications), start from the parent repository and follow the

steps described below. The description uses the [Eliza app](https://github.com/leolani/eliza-parent) as example.



### Check-out



To check out all code needed for the Eliza App, follow the instructions in the

[Eliza app](https://github.com/leolani/eliza-parent).



### Build and run the application



The application is structured into separate components which have their own *git* repositories

and can be run as separate Python applications. The parent repository of the application contains

all those component repositories as *git* submodules.



There is a central application ([cltl-eliza-app](https://github.com/leolani/cltl-eliza-app)) that configures and runs

all the necessary components it needs, either inside a Python application or as containerized services in a *Kubernetes*

cluster or using *docker compose*. To run the application, first all components need to be packaged and made available

to the application. For this purpose there are *makefiles* available in the components and the application parent that

automate this process. To build the application run



    make build



from the **parent repository**. This command will download external dependencies to

[cltl-requirements](https://github.com/leolani/cltl-requirements), setup virtual environments for all components,

package them and publish the packages to [cltl-requirements](https://github.com/leolani/cltl-requirements) to make them

available to the application and other components.



To run the application follow the instructions in the [Eliza qparent](https://github.com/leolani/eliza-parent).



### Make changes to the code



Individual components in the parent repository are edited and committed separately, and, after a stable version is

reached, the state of the components is commited in the parent repository, for the workflow see

[Working with git submodules](HOWTO/gitsubmodules.md).   

Modularization allows developing components in isolation. The application and other components depend on a packaged

version of a component only, therefore changes will become available outside of the component only after rebuilding

the application, see above.



To use PyCharm for development see the instructions in [Workflow using PyCharm](HOWTO/pycharm.md).



To commit changes made to the application see the instructions in [Working with git submodules](HOWTO/gitsubmodules.md).



### Adding a new component



To add a new component to an application follow the instruction in the

[template component](https://github.com/leolani/cltl-template).



### Create a new application



### HOWTOs



* [Workflow using PyCharm](HOWTO/pycharm.md)

* [Working with git submodules](HOWTO/gitsubmodules.md)

* [Setup a new component](https://github.com/leolani/cltl-template.git)

* [Add a component to a Python app]()



## Content of this repository



This repo provides infrastructre and general code for the platform:



### Infrastructure



The `cltl.combot.infra` module contains library code for infrastructre used in

qthe application.



#### Event bus



Components of the application can communicate via an event bus. The

`cltl.combot.infra.event` module provides the interface and different implementations

of the event bus.



The `cltl.combot.infra.topic_worker` module provides a convenience class to

implement the subscription to one or multiple topics in the event bus.



#### Configuration manager



Configuration is made available in the application via a configuration manager.

The `cltl.combot.infra.config` module provides the interface and different

implementations of the configuration manager.



#### Resource manager



Access to resources in the application is made available via a resource manager.

This includes providing resources and waiting for resources to become available

as well as managing access to shared resources. The `cltl.combot.infra.resource`

module provides the interface and different implementations of the resource

manager.



#### Time util



The `cltl.combot.infra.time_util` module provides time related utilities to

ease the usage of a consistent time format throughout the application.



#### Dependency injection



The `cltl.combot.infra.di_container` module provides a simple utility to use

dependency inject in the application.
