## Rationale

These utilities are meant to solve a problem with related repositories and their dependency relationships

Projects may have hierarchical dependencies.  See the following [Pyut](https://github.com/hasii2011/PyUt) dependency diagram.

```

The above diagram illustrates how low-level dependencies ripple up the dependency tree.  

## Dependency Locations

Additionally, projects may specify dependencies in different places.  Examples of the dependency locations are

* setup.py
* requirements.txt
* .circleci/config.yml
* .travis.yml



## Python Console Scripts

VersionOverlord means to handle this problem by providing a set of Python command line scripts to automate updating the first three of the above dependency specification locations

* querySlugs          -- queries repositories for their latest release version
* createSpecification -- creates a dependency specification for a project 
* updateDependencies  -- updates the supported dependency locations using the generated specification



## Required Environment Variables

The above commands depend on the following environment variables.

```bash
GITHUB_ACCESS_TOKEN - A personal GitHub access token necessary to read repository release information
PROJECTS_BASE             - The local directory where the python projects are based
PROJECT                          - The name of the project;  It should be a directory name
```

See the [GitHub Documentation](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token) for instructions on how to create a usable access token.  These scripts assume  that a developer keeps all checked out repositories in a single directory.  An example, of a PROJECTS_BASE is:

```bash
export PROJECTS_BASE="${HOME}/PycharmProjects" 
```

This should be set in your shell startup script.  For example `.bash_profile`.

The developer sets the PROJECT environment variable on a project by project basis.  
I recommend you use [direnv](https://direnv.net) to manage these.  
An example of a .envrc follows:

```bash
export PROJECT=pyutmodel
source pyenv-3.10.6/bin/activate
```

## Advanced Slugs

The command line options for querySlug and createSpec are advanced GitHub slugs.  For example, for the following repositories

https://github.com/hasii2011/pyutmodel

https://github.com/hasii2011/hasiicommon

https://github.com/hasii2011/code-ally-basic

The slugs are `hasii2011/pyutmodel` and `hasii2011/hasiicommon` and `hasii2011/code-ally-basic,codeallybasic`, respectively.
Note the advanced part of the third slugs because the package name does not match the repository name;  



## Usage

From the above dependency diagram assume the following:

Both the `pyutmodel` and `hasiicommon` repositories have been updated.  We need to update the `ogl` dependencies to match the latest of both.  Assume both `GITHUB_ACCESS_TOKEN` and `PROJECTS_BASE` are correctly set and `PROJECT` is set to `'ogl'`.  Use the following CLI invocation to create the specification file.

```
createSpecification -s hasii2011/pyutmodel -s hasii2011/hasiicommon
```

The command creates the file `versionSpecification.csv` with the following contents.

```
PackageName,OldVersion,NewVersion
pyutmodel,1.4.0,1.4.1
hasiicommon,0.0.7,0.1.0                   
```

Again assuming, the previously mentioned environment variables are set the following CLI invocation;

```
updateDependencies
```

correctly updates the following

* setup.py
* requirements.txt
* .circleci/config.yml

## Installation

```
pip install versionoverlord
```

I am concerned about GitHub's Copilot project

![](https://github.com/hasii2011/code-ally-basic/blob/master/developer/SillyGitHub.png)

I urge you to read about the
[Give up GitHub](https://GiveUpGitHub.org) campaign from
[the Software Freedom Conservancy](https://sfconservancy.org).

While I do not advocate for all the issues listed there, I do not like that
a company like Microsoft may profit from open source projects.

I continue to use GitHub because it offers the services I need for free.  
I continue to monitor their terms of service.

Any use of this project's code by GitHub Copilot, past or present, is done
without my permission.  I do not consent to GitHub's use of this project's
code in Copilot.
