🕶 file-mapper

file-mapper is a versatile CLI tool that combines the power of the Linux tree command (for hierarchical directory listings) and the cat command (for file content viewing)—all rolled into one convenient package. Recursively map out your project structure, filter files, and optionally display file contents (with features like line numbering). It's ideal for developers who want a comprehensive project overview or need to share both file structure and content with others (e.g., in code reviews or AI tools).

Features

1. Tree or Flat

   • By default, file-mapper displays a hierarchical tree of your files and directories (like tree).
   • Use the --flat flag for a flat listing instead.

2. Git-Tracked-Only

   • Restrict the output to only files that are tracked by Git (--git).

3. Include / Exclude Patterns

   • Filter specific file types (e.g. --include="*.go,*.md")
   • Exclude directories/files (e.g. --exclude=".git,node_modules").

4. Hidden & Binary Skips

   • Hidden files/directories (those starting with .) are ignored by default.
   • Uses a naive approach to skip binary files.

5. Content Viewing

   • Inline content right below each file (similar to cat, but recursive) (--content).
   • Or separate: list all files, then dump their contents afterward.
   • Enable line numbers (--line-numbers) for quick reference.
   • Show or hide content headers (----- CONTENT START ----- / ----- CONTENT END -----).

6. Output to File

   • Save your entire listing and contents to a file (--output=out.txt).

Why Use file-mapper?

• One-Stop Command: Instead of running tree to see the structure and then cat or less for file contents, file-mapper does it all in one go, recursively.
• Share With AI or Peers: Perfect for pasting a project’s structure and file contents into ChatGPT or sending it to teammates.
• Saves Time: No manual copy-pasting or multiple commands—filter, track only Git files, and see everything at a glance.

Installation

Make sure you have Go 1.18+ installed, then run:

go install github.com/sky93/file-mapper@latest

This will download, build, and install the file-mapper binary (the main CLI for file-mapper) into your Go bin directory (e.g., ~/go/bin).

Tip: Ensure your ~/go/bin (or the equivalent on your system) is in your $PATH so that you can run file-mapper from anywhere.

Usage

Once installed:

file-mapper [flags...]

Alternatively, if you cloned the repo locally and want to run without installing:

git clone https://github.com/sky93/file-mapper.git
cd file-mapper/cmd/projectMapper
go run main.go [flags...]

Examples

1. Default Tree

   file-mapper
   

   • Displays the folder/file structure in a tree.
   • Skips hidden directories and binary files.

2. Display File Contents Inline

   file-mapper --content
   

   • Combines tree + cat for each file, printing content right below the file.

3. Only Git-Tracked Files

   file-mapper --git
   

   • Recursively traverses your directories, showing only files tracked by Git.

4. Tree + Separate Content

   file-mapper --content --separate-content
   

   • Prints the tree, then appends file contents at the end.

5. Flat Listing

   file-mapper --flat
   

   • Shows a simple list of files/directories.

6. Include/Exclude Patterns

   file-mapper --include="*.go,*.txt" --exclude=".git,.idea,node_modules"
   

7. Output to a File

   file-mapper --output=map.txt
   

   • Saves the entire listing and optional content to map.txt.

8. Line Numbers + Content

   file-mapper --content --line-numbers
