@ -6,50 +6,61 @@ This helps to protect against installing broken dotfiles by providing a way to r
|
|||
and return the system back to the previous state.
|
||||
|
||||
The installation process creates symbolic links, much like what you would expect when using [stow](https://linux.die.net/man/8/stow).
|
||||
`kot` can install dotfiles from any directory, using any target directory. To test how `kot` might behave,
|
||||
you could point `--install-dir` to any directory that you've created for testing.
|
||||
This directory could be empty, or it could contain another set of dotfiles. `kot` will attempt
|
||||
to install the configurations. If conflicts are detected, output shows the conflicts and
|
||||
`kot` can install dotfiles from any source directory, to any target directory.
|
||||
To test how `kot` might behave, you could point `--install` to any directory that you've created for testing.
|
||||
This directory could be empty, or it could contain another set of dotfiles.
|
||||
Alternatively, you could set the `--dry-run` flag that will automatically install to a predefined path (`$HOME/.local/share/kot/dry-runs/$USER`)
|
||||
Note that this directory will never be cleared automatically, each subsequent `--dry-run`
|
||||
will stack configurations into this default directory until it is manually cleared.
|
||||
|
||||
If conflicts are detected, `kot` shows the conflicts found and
|
||||
prompts to abort or continue. An example of this is seen below.
|
||||
This prompt will be skipped if the `--force` flag is set.
|
||||
|
||||
```bash
|
||||
kot dotfiles/dot/
|
||||
|
||||
args: Cli { dotfiles_dir: "/home/kapper/Code/kot/dotfiles/dot", install_dir: "/home/kapper/Code/kot/dry-runs/kapper", backup_dir: "/home/kapper/Code/kot/backups/kapper", force: false }

|
||||
If you continue, backups will be made in "/home/kapper/.local/share/kot/backups/dot:2022-05-29T19:03:27".
|
||||
Any configurations there will be overwritten.
|
||||
Continue? Enter Y/y or N/n:
|
||||
|
||||
|
||||
```
|
||||
|
||||
If there are already files within the backup directory, `kot` will exit and show an error message.
|
||||
This is to protect existing backups from being merged with configs from subsequent runs.
|
||||
If you want to erase these backups and create a new backup, rerun the command with the `--force` flag set.
|
||||
Otherwise, specify a different backup directory with the `--backup-dir` option.
|
||||
If the backup directory does not exist, it will be created.
|
||||
#### User Data
|
||||
|
||||
`kot` stores user data within `$HOME/.local/share/kot/`
|
||||
|
||||
```bash
|
||||
kot dotfiles/dot/
|
||||
When we provide a repository URL as our `dotfiles` to install, the repo will be *recursively* cloned into
|
||||
`$HOME/.local/share/kot/dotfiles/<REPO_NAME>`.
|
||||
This is to ensure each user of `kot` maintains their own dotfiles in a location that is accessible but not easy to accidentally modify or erase.
|
||||
If needed, the user can provide a preferred clone directory to the CLI by setting the `--clone-dir` option
|
||||
|
||||

||||
Error: Backups already exist at "/home/kapper/Code/kot/backups/kapper"
|
||||
Set the --force flag to overwrite configurations stored here', src/kot/kcli.rs:94:17
|
||||
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
|
||||
```
|
||||
When we encounter conflicts during installation of these dotfiles, backups will be created in
|
||||
`$HOME/.local/share/kot/backups/<DOTFILES_NAME>:<DATE(%Y-%m-%dT%H:%M:%S)>`
|
||||
If there are no conflicts found during installation, no backup is created.
|
||||
Configurations are said to be conflicting if the `--install` path contains configuration files that are
|
||||
also within the dotfiles we are currently installing.
|
||||
|
||||
#### Installation
|
||||
Backups are intended to reverse changes applied during installation of dotfiles.
|
||||
These backups are not exhaustive of all configurations tied to the system or user.
|
||||
The backups only include files that were direct conflicts with configurations being installed.
|
||||
When we reach an error during installation, `kot` will restore the configurations within the last backup, and then removes unused configurations.
|
||||
|
||||
#### Installing kot
|
||||
|
||||
Follow [Rustup instructions](https://rustup.rs/) to setup the Rust toolchain

Installs configurations to $HOME/.local/shared/kot/dry-runs
|

|

Useful flag to set when testing what an install would do to your home directory. This is synonymous with
|

setting --install $HOME/.local/shared/kot/dry-runs/$USER. Subsequent runs with this flag set will not delete
|
||||
the contents of this directory.
|

-f, --force

Overwrites existing backups
|

|

This flag will replace existing backups if during installation we encounter conflicts and the backup-dir

||||
provided already contains previous backups.
|
||||
-h, --help
|

OPTIONS:
|

-b, --backup-dir <backup-dir>
|
||||
The location to store backups for this user
|
||||
|
||||
If no backup-dir is provided, we create one within the default kot data directory:
|
||||
$HOME/.local/share/kot/backups/
|
||||
-c, --clone-dir <clone-dir>
|
||||
An alternate path to clone a dotfiles repository to
|
||||
|
||||
If the clone-dir option is provided to the CLI, kot will clone the dotfiles repository into this directory.
|
||||
If clone-dir is not provided, the repository is cloned into $HOME/.local/share/kot/dotfiles Custom clone-dir
|
||||
will be used literally, and no subdirectory is created to store the cloned repository For example, clone-dir
|
||||
of $HOME/clonedir for repo named Dotfiles We will clone into $HOME/clonedir, and NOT $HOME/clonedir/Dotfiles
|
||||
The default path for cloned repos is $HOME/.local/share/kot/dotfiles/
|
||||
-i, --install <install>
|
||||
The location to attempt installation of user configurations
|
||||
|
||||
The desired installation directory for user configurations. By default this is your $HOME directory This
|
||||
could optionally point to some other directory to perform a dry run, or the --dry-run flag could be set
|
||||
[env: HOME=/home/kapper]
|
||||
|
||||
ARGS:
|
||||
<dotfiles>
|
||||
Local or full path to user configurations to install. Can also be a git repository.
|
||||
|
||||
System path or repository URL for dotfiles we want to install. If a path is used, it can either be local to
|
||||
CWD or absolute. If a URL is used for a dotfiles repository, the repo is cloned into
|
||||
$HOME/.local/shared/kot/dotfiles/
|
||||
```
|
||||
|
||||
If you don't want to install `kot`, you can also use the following `cargo` command
|
||||
where all arguments after the `--` are passed as arguments to `kot` and not `cargo`.
|

Below is an example of the short-help output text provided with the `-h` flag

#### Dotfiles Management
|
||||
#### TODO
|
||||
|
||||
To store dotfiles, this repository uses submodules. To update surface-level submodules, we can run the following commands
|
||||
```bash
|
||||
git submodule update --init
|
||||
|
||||
Submodule path 'dot': checked out '7877117d5bd413ecf35c86efb4514742d8136843'
|
||||
```
|
||||
|
||||
But in the case of my dotfiles repository, [shaunrd0/dot](https://gitlab.com/shaunrd0/dot), I use submodules to clone repositories for vim plugins. To update all submodules *and their nested submodules*, we can run the following commands
|
||||
```bash
|
||||
git submodule update --init --recursive
|
||||
|
||||

```
|
||||
* Ensure empty backups are not created
|
||||
* Provide interface for managing agreed-upon /etc/skel/ configurations
|
||||
* Provide more CLI options for git functionality; Branches, update submodules, etc
|
||||
* Clean up warnings during build / installation
|
||||
* Automate testing
|
||||
*
