## How to Pay Respects

Please follow the instruction for your shell:

<details>
	<summary>Bash / Zsh / Fish</summary>

> Append the following line to your configuration file:
> ```shell
> eval "$(pay-respects bash --alias)"
> eval "$(pay-respects zsh --alias)"
> pay-respects fish --alias | source
> ```
> Arguments:
> - `--alias [alias]`: Alias to a custom key, defaults to `f`
> - `--nocnf`: Disables `command_not_found` handler

> Manual aliasing (**DEPRECATED**, do not use):
> ```shell
> alias f="$(pay-respects bash)"
> alias f="$(pay-respects zsh)"
> alias f="$(pay-respects fish)"
> ```

</details>

<details>
	<summary>Nushell</summary>

> Add the following output to your configuration file:
> ```shell
> pay-respects nushell --alias [<alias>]
> ```

> Or save it as a file:
> ```shell
> pay-respects nushell --alias [<alias>] | save -f ~/.pay-respects.nu
> ```
> and source from your config file:
> ```shell
> source ~/.pay-respects.nu
> ```

</details>

<details>
	<summary>PowerShell</summary>

> Append the following to your profile:
> ```pwsh
> pay-respects pwsh --alias [<alias>] [--nocnf] [>> $PROFILE] # use the pipe to directly append it to your profile if you like
> ```

</details>

<details>
	<summary>Custom initialization for arbitrary shell</summary>

> pay-respects only requires 2 environment variables to function:
>
> - `_PR_SHELL`: The binary name of the current working shell.
> - `_PR_LAST_COMMAND`: The last command.
>
> pay-respects echos back, if applicable, a `cd` command that can be evaluated by the current working shell.

> General example:
> ```shell
> eval $(_PR_SHELL=sh _PR_LAST_COMMAND="git comit" pay-respects)
> ```

</details>

<details>
	<summary>Environment variable configurations</summary>

> - `_PR_LIB`: Directory of modules, analogous to `PATH`. If not provided, search in `PATH` or compile-time provided value.
> - `_PR_PACKAGE_MANAGER`: Use defined package manager instead of auto-detecting alphabetically

	<summary>AI and API Configuration</summary>

> Configuration is done via environment variables:
>
> - `_PR_AI_API_KEY`: Your own API key
> - `_PR_AI_URL`: URL used. Any OpenAI compatible URL can be used, e.g.:
>	- `https://api.openai.com/v1/chat/completions` (Note: OpenAI's ChatGPT is very slow)
>	- `https://api.groq.com/openai/v1/chat/completions`
> - `_PR_AI_MODEL`: Model used
> - `_PR_AI_DISABLE`: Setting to any value disables AI integration
> - `_PR_AI_LOCALE`: Locale in which the AI explains the suggestion. Defaults to user system locale

> Compile time variables: Default values for the respective variables above when not set
>
> - `_DEF_PR_AI_API_KEY`
> - `_DEF_PR_AI_URL`
> - `_DEF_PR_AI_MODEL`
>
>  If default values were not provided, pay-respects' own values will be used. Your request will be filtered to avoid abuse usages. Request will then be forwarded to a LLM provider that will not use your data for training.
