VarAI

An AI-powered tool that recommends variable names with Ollama, ChatGPT, Gemini, Claude, Mistral and other AI

Introduction

VarAI is a cutting-edge command-line tool that leverages diverse AI techniques to provide tailored recommendations for variable names in your projects. Unlock the power of AI to streamline your coding process and effortlessly craft meaningful variable names, tailored to your needs.

Supported Providers

Remote

• OpenAI
• Anthropic Claude
• Gemini
• Mistral AI
• Huggingface (Unofficial)
• Clova X (Unofficial)

Local

• Ollama

Setup

The minimum supported version of Node.js is the v18. Check your Node.js version with node --version.

• Install VarAI:

npm install -g varai

• Retrieve and set API keys or Cookie you intend to use:

It is not necessary to set all keys. But at least one key must be set up.

You may need to create an account and set up billing.

• OpenAI

varai config set OPENAI_KEY=<your key>

• Anthropic Claude

varai config set ANTHROPIC_KEY=<your key>

• Gemini

varai config set GEMINI_KEY=<your key>

• Mistral AI

varai config set MISTRAL_KEY=<your key>

• Huggingface (Unofficial)

# Please be cautious of Escape characters(\", \') in browser cookie string 
varai config set HUGGING_COOKIE="<your browser cookie>"

• Clova X (Unofficial)

# Please be cautious of Escape characters(\", \') in browser cookie string 
varai config set CLOVAX_COOKIE="<your browser cookie>"

This will create a .varai file in your home directory.

• Run VarAI with your staged in git repository:

varai -m "this class is for generating variable names"

Using Locally

You can also use your model for free with Ollama and is available to use both Ollama and remote providers simultaneously.

• Install Ollama from https://ollama.com

• Start it with your model

ollama run llama3 # model you want use. ex) codellama, deepseek-coder

• Set the model and host

varai config set OLLAMA_MODEL=<your model> 
varai config set OLLAMA_HOST=<host> # Optional. The default host for ollama is http://localhost:11434.
varai config set OLLAMA_TIMEOUT=<timout> # Optional. default is 100000ms (100s)

If you want to use ollama, you must set OLLAMA_MODEL.

• Run VarAI with your staged in git repository

varai -m "this class is managing session"

Usage

CLI mode

You can call varai directly to generate a variable name for your message:

varai -m "class names for managing session"

CLI Options

--message or -m

• Message that represents the user's request or instruction to your AI (Required)

varai --message "Please generate some class names for managing session"  # or -m <s>

--language or -l

• Code Language to use for the generated variables

varai --language <s> # or -l <s>

--generate or -g

• Number of messages to generate (Warning: generating multiple costs more) (default: 3)

varai --generate <i> # or -g <i>

Warning: this uses more tokens, meaning it costs more.

--prompt or -p

• Additional prompt to let users fine-tune provided prompt

varai --prompt <s> # or -p <s>

--clipboard or -c

• Copy the selected variable name to the clipboard (default: true)

varai --clipboard=false # or -c=false

Configuration

Reading a configuration value

To retrieve a configuration option, use the command:

varai config get <key>

For example, to retrieve the API key, you can use:

varai config get OPENAI_KEY

You can also retrieve multiple configuration options at once by separating them with spaces:

varai config get OPENAI_KEY OPENAI_MODEL GEMINI_KEY 

Setting a configuration value

To set a configuration option, use the command:

varai config set <key>=<value>

For example, to set the API key, you can use:

varai config set OPENAI_KEY=<your-api-key>

You can also set multiple configuration options at once by separating them with spaces, like

varai config set OPENAI_KEY=<your-api-key> generate=3 language=C++

Common Options

language

Code Language to use for the generated variables. (ex. typescript, c++)

generate

Default: 3

The number of variable names to generate to pick from.

Note, this will use more tokens as it generates more results.

proxy

Set a HTTP/HTTPS proxy to use for requests.

To clear the proxy option, you can use the command (note the empty value after the equals sign):

Only supported within the OpenAI

varai config set proxy=

timeout

The timeout for network requests to the OpenAI API in milliseconds.

Default: 10000 (10 seconds)

varai config set timeout=20000 # 20s

max-length

The maximum character length of the generated variable names.

Default: 15

varai config set max-length=30

max-tokens

The maximum number of tokens that the AI models can generate.

Default: 200

varai config set max-tokens=1000

temperature

The temperature (0.0-2.0) is used to control the randomness of the output
