system-updater/README.md

# Description
A tool to help keeping your system up to date.

This tool will remember the applications you installed and update them all (even from a git repo). To do that you will need to configure all the commands you want to run when upgrating your system (see the `example_config` folder).

See also [topgrade](https://github.com/topgrade-rs/topgrade) for a solution that auto-detect everything it can.

# Roadmap
* [X] Run commands found in different configuration files
* [X] Have Pre / Post commands to do before / after the upgrade
* [X] Do all the installations and give a summary of success and errors at the end
* [X] Improve errors ^^'
* [ ] Executors from a packagers need to be executed in order and only if all of the previous failed
* [ ] Tests
* [ ] Prevent the usage of `sudo` and equivalent, add a config to say "needAdminRights"
* [ ] Parallel execution of commands
  * [ ] Packagers need to state their dependency
  * [ ] Show a progress bar general and the list of task in execution (with their stepNumber): "helix PostInstall (1/2)"
  * [ ] All input should be prevented (even asking for `sudo`’s password)
  * [ ] All output (standard and errors) needs to be redirected in files. Maybe something like: /tmp/system-updater/<DATETIME>-<packagerName>-<executorName?/stepNumber??>.log
* [ ] Start self and command "Nicer" (Not sure it is possible in all systems, or in the same way)
* [ ] Documentation
  * [X] Readme
  * [ ] Code

## Nice to have
* [ ] Being usable as a lib (I set the minimum possible in main.rs but the insterface have not been thought out)
  * [ ] Being given a directory and/or a list of files
  * [ ] Being given an already populated `Updater`’s struct
* [ ] Have subcommands to interactively act on packagers’s config
  * [ ] List
  * [ ] Show
  * [ ] Create
  * [ ] Delete
  * [ ] Update? (Bad way: Show + Delete + Create? ^^')
* [ ] More config examples
  * [ ] System executors for all/most famous systems (openSUSE, Fedora, Arch, …)
  * [ ] At least an example of binary downlowd (curl or wget)

# Usage
The configuration folder is at [the standard path for configuration on your system](https://docs.rs/directories/latest/directories/struct.ProjectDirs.html#method.config_dir) and the commads should be in the packagers subfolder.
Example on linux it is at `~/.config/systemupdater/packagers/`

Just start the program, no option needed in you day to day usage.
```sh
sup
```

# Installation
```sh
cargo install --locked system-updater
```
