# lmcli - Large Language Model CLI
|
||||||
|
|
||||||
`lmcli` is a (Large) Language Model CLI.
|
`lmcli` is a versatile command-line interface for interacting with LLMs and LMMs.
|
||||||
|
|
||||||
Current features:
|
## Features
|
||||||
- Perform one-shot prompts with `lmcli prompt <message>`
|
|
||||||
- Manage persistent conversations with the `new`, `reply`, `view`, `rm`,
|
|
||||||
`edit`, `retry`, `continue` sub-commands.
|
|
||||||
- Syntax highlighted output
|
|
||||||
- Tool calling, see the [Tools](#tools) section.
|
|
||||||
|
|
||||||
Maybe features:
|
- Multiple model backends (Ollama, OpenAI, Anthropic, Google)
|
||||||
- Chat-like interface (`lmcli chat`) for rapid back-and-forth conversations
|
- Customizable agents with tool calling
|
||||||
- Support for additional models/APIs besides just OpenAI
|
- Persistent conversation management
|
||||||
|
- Interactive terminal interface for seamless chat experiences
|
||||||
|
- Syntax highlighting!
|
||||||
|
|
||||||
## Tools
|
## Screenshots
|
||||||
Tools must be explicitly enabled by adding the tool's name to the
|
|
||||||
`openai.enabledTools` array in `config.yaml`.
|
|
||||||
|
|
||||||
Note: all filesystem related tools operate relative to the current directory
|
[TODO: Add screenshots of the TUI in action, showing different views and features]
|
||||||
only. They do not accept absolute paths, and efforts are made to ensure they
|
|
||||||
cannot escape above the working directory). **Close attention must be paid to
|
|
||||||
where you are running `lmcli`, as the model could at any time decide to use one
|
|
||||||
of these tools to discover and read potentially sensitive information from your
|
|
||||||
filesystem.**
|
|
||||||
|
|
||||||
It's best to only have tools enabled in `config.yaml` when you intend to be
|
## Installation
|
||||||
using them, since their descriptions (see `pkg/cli/functions.go`) count towards
|
|
||||||
context usage.
|
|
||||||
|
|
||||||
Available tools:
|
To install `lmcli`, make sure you have Go installed on your system, then run:
|
||||||
|
|
||||||
- `read_dir` - Read the contents of a directory.
|
```sh
|
||||||
- `read_file` - Read the contents of a file.
|
go install git.mlow.ca/mlow/lmcli@latest
|
||||||
- `write_file` - Write contents to a file.
|
|
||||||
- `file_insert_lines` - Insert lines at a position within a file. Tricky for
|
|
||||||
the model to use, but can potentially save tokens.
|
|
||||||
- `file_replace_lines` - Remove or replace a range of lines within a file. Even
|
|
||||||
trickier for the model to use.
|
|
||||||
|
|
||||||
## Install
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ go install git.mlow.ca/mlow/lmcli@latest
|
|
||||||
```
|
```
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
`lmcli` uses a YAML configuration file located at `~/.config/lmcli/config.yaml`. Here's a sample configuration:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
defaults:
|
||||||
|
model: claude-3-5-sonnet-20240620

|
||||||
|
|
||||||

|
### Examples
|
||||||
|
|
||||||
Refer back to the output of `lmcli help` for usage.
|
Start a new chat with the `code-helper` agent:
|
||||||
|
|
||||||
Enjoy!
|
```console
|
||||||
|
$ lmcli chat --agent code-helper
|
||||||
|
```
|
||||||
|
|
||||||
|
Start a new conversation, imperative style (no tui):
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ lmcli new "Help me plan meals for the next week"
|
||||||
|
```
|
||||||
|
|
||||||
|
Send a one-shot prompt (no persistence):
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ lmcli prompt "What is the answer to life, the universe, and everything?"
|
||||||
|
```
|
||||||
|
|
||||||
|
## Agents
|
||||||
|
|
||||||
|
Agents in `lmcli` are configurations that combine a system prompt with a set of available tools. You can define agents in the `config.yaml` file and switch between them using the `--agent` or `-a` flag.
|
||||||
|
|
||||||
|
Example:
|
||||||
|
```sh
|
||||||
|
lmcli chat -a financier
|
||||||
|
```
|
||||||
|
|
||||||
|
## Tools
|
||||||
|
|
||||||
|
`lmcli` supports tool calling. The following built-in tools are currently available:
|
||||||
|
|
||||||
|
- `dir_tree`: Display a directory structure
|
||||||
|
- `read_file`: Read the contents of a file
|
||||||
|
- `write_file`: Write content to a file
|
||||||
|
- `file_insert_lines`: Insert lines at a specific position in a file
|
||||||
|
- `file_replace_lines`: Replace a range of lines in a file
|
||||||
|
|
||||||
|
Obviously, some of these tools carry significant risk. Use wisely :)
|
||||||
|
|
||||||
|
More tool features are planned, including the to define arbitrary tools which call out to external scripts, tools to spawn sub-agents, perform web searches, etc.
