fyai

A command-line tool to combine files from a directory into a single file for AI processing, with flexible filtering options.

Features

• Combines multiple text files into one output file
• Supports configuration via CLI options and config files (YAML)
• Filters files by:
  • Size
  • File extensions (e.g., .txt, .md)
  • Directory inclusion/exclusion
  • File inclusion/exclusion
  • Optionally respects .gitignore rules (can be disabled)
• Preserves file boundaries with headers showing filename and size
• Customizable input directory and output file

Installation

Prerequisites

• Rust (latest stable version recommended)

Install via Cargo

cargo install feedyourai

Or,

cargo install --git https://github.com/alexandretrotel/feedyourai.git

This installs the fyai binary to ~/.cargo/bin/. Ensure this directory is in your PATH.

Usage

Run fyai in your terminal to combine files:

Config File Support

You can specify options in a config file (YAML format):

• Local config: ./fyai.yaml (used if present in current directory)
• Global config: ~/.config/fyai.yaml (used if no local config found)
• Precedence: Local config overrides global config. CLI options override both config files.

Example fyai.yaml

directory: ./src
output: combined.txt
include_ext:
  - md
  - txt
exclude_dirs:
  - node_modules
  - dist
min_size: 10240
max_size: 512000
respect_gitignore: true
tree_only: false

All CLI options can be set in the config file. CLI flags always take precedence.

Basic Usage

fyai

• Combines all files from the current directory into fyai.txt

Examples

• Combine only .txt and .md files from a specific directory:

  fyai -d ./docs --include-ext txt,md
  

• Exclude all .log and .tmp files from the output:

  fyai --exclude-ext log,tmp
  

• Include only files named README.md and main.rs from the src and docs directories:

  fyai --include-dirs src,docs --include-files README.md,main.rs
  

• Exclude all files named LICENSE and config.json from any directory:

  fyai --exclude-files LICENSE,config.json
  

• Include all files (no size minimum) up to 1MB:

  fyai -n 0 -m 1048576
  

• Custom output file with files between 10KB and 500KB, excluding dist and node_modules directories:

  fyai -n 10240 -m 512000 -o ai_input.txt -x dist,node_modules
  

• Output only the project directory structure (no file contents):

  fyai --tree-only -o tree.txt
  

• Ignore .gitignore rules and include all files (even those normally excluded):

  fyai --respect-gitignore false
  

Output Format

The combined file includes headers for each source file:

=== File: example.txt (12345 bytes) ===
[contents of example.txt]

=== File: notes.md (67890 bytes) ===
[contents of notes.md]
