aichat -e install nvim                          # Execute
aichat -c fibonacci in js                       # Code

aichat -s                                       # REPL + New session
aichat -s session1                              # REPL + New/Reuse 'session1'

aichat -r role1 --info                          # View role info
aichat -s session1 --info                       # View session info

cat data.toml | aichat -c to json > data.json   # Pipe stdio/stdout

aichat -f data.toml -c to json > data.json      # Attach files

aichat -f a.png -f b.png diff images            # Attach images

Shell commands

Simply input what you want to do in natural language, and aichat will prompt and run the command that achieves your intent.

aichat -e <text>...

Aichat is aware of OS and shell you are using, it will provide shell command for specific system you have. For instance, if you ask aichat to update your system, it will return a command based on your OS. Here's an example using macOS:

$ aichat -e update my system
# sudo softwareupdate -i -a
? [1]:execute [2]:explain [3]:revise [4]:cancel (1)

The same prompt, when used on Ubuntu, will generate a different suggestion:

$ aichat -e update my system
sudo apt update && sudo apt upgrade -y
? [1]:execute [2]:explain [3]:revise [4]:cancel (1)

Shell integration

This is a very handy feature, which allows you to use aichat shell completions directly in your terminal, without the need to type aichat with prompt and arguments. This feature puts aichat completions directly into terminal buffer (input line), allowing for immediate editing of suggested commands.

To install shell integration, go to ./scripts/shell-integration to download the script and source the script in rc file. After that restart your shell. You can invoke the completion with alt+e hotkey.

Generating code

By using the --code or -c parameter, you can specifically request pure code output.

The -c/--code option ensures the extraction of code from Markdown.

Chat REPL

Aichat has a powerful Chat REPL.

REPL Features:

• Convenient Tab Autocompletion: Get suggestions for commands and functions while typing.
• Customizable REPL Prompt: Personalize the REPL interface by defining your own prompt.
• Streamlined Keybindings: Use familiar Emacs/Vi keybindings for efficient navigation and editing.
• Multi-line Editing: Create and edit multi-line inputs with ease.
• External Editor Integration: Open an external editor to refine the current inputs or write longer inputs.
• History and Undo Support: Access previously executed commands and undo any actions you make.

.model - choose a model

> .model openai:gpt-4
> .model ollama:llama2

You can easily enter model name using tab autocompletion.

.role - let the AI play a role

Select a role:

> .role emoji

Send message with the role:

emoji> hello
👋

Leave current role:

emoji> .exit role

> hello
Hello there! How can I assist you today?

Show role info:

emoji> .info role
name: emoji
prompt: I want you to translate the sentences I write into emojis. I will write the sentence, and you will express it with emojis. I just want you to express it with emojis. I don't want you to reply with anything but emoji. When I need to tell you something in English, I will do it by wrapping it in curly brackets like {like this}.
temperature: null

Temporarily use a role to send a message.

> ::: .role emoji
hello world
:::
👋🌍

> 

.session - context-aware conversation

By default, aichat behaves in a one-off request/response manner.

You should run aichat with -s/--session or use the .session command to start a session.

> .session

temp) 1 to 5, odd only                                                                    0
1, 3, 5

temp) to 7                                                                        19(0.46%)
1, 3, 5, 7

temp) .exit session                                                               42(1.03%)
? Save session? (y/N)  

The prompt on the right side is about the current usage of tokens and the proportion of tokens used, compared to the maximum number of tokens allowed by the model.

.prompt - make a temporary role using a prompt

There are situations where setting a system message is necessary, but modifying the roles.yaml file is undesirable. To address this, we leverage the .prompt to create a temporary role specifically for this purpose.

> .prompt write unit tests for the rust functions

%%>

.file - include files with the message

Usage: .file <file>... [-- text...]

.file message.txt
.file config.yaml -- convert to toml
.file a.jpg b.jpg -- What’s in these images?
.file https://ibb.co/a.png https://ibb.co/b.png -- what is the difference?

Only the current model that supports vision can process images submitted through .file command.

.set - modify the configuration temporarily

.set temperature 1.2
.set compress_threshold 1000
.set dry_run true
.set highlight false
.set save false
.set save_session true
.set auto_copy true

Roles

We can define a batch of roles in roles.yaml.

Get roles.yaml path with command aichat --info or repl command .info.

For example, we can define a role:

- name: shell
  prompt: >
    I want you to act as a Linux shell expert.
    I want you to answer only with bash code.
    Do not provide explanations.    

Let LLM answer questions in the role of a Linux shell expert.

> .role shell

shell>  extract encrypted zipfile app.zip to /tmp/app
mkdir /tmp/app
unzip -P PASSWORD app.zip -d /tmp/app
