2. Prerequisites for Installing GRV#

Before installing GRV, ensure your Linux system meets these requirements:

• Git: Installed and configured (required to interact with repositories). Verify with git --version.
• Linux Distro: Any modern distro (Ubuntu, Fedora, Arch, etc.).
• Build Essentials (Optional): For compiling from source (requires build-essential on Debian/Ubuntu, development-tools on Fedora).
• Go Language (Optional): Needed if you plan to build GRV from source (version 1.11 or later recommended).

To install Git on Debian/Ubuntu:

sudo apt update && sudo apt install git

On Fedora/RHEL:

sudo dnf install git

3. Installing GRV on Linux#

GRV can be installed via package managers (for most distros) or compiled from source. Below are step-by-step instructions for common Linux distributions:

3.1 Ubuntu/Debian-based Distros#

Download the official .deb package from the GRV releases page and install it:

# Replace X.X.X with the latest version number
wget https://github.com/rgburke/grv/releases/download/vX.X.X/grv_X.X.X_amd64.deb
sudo dpkg -i grv_X.X.X_amd64.deb
# Fix any missing dependencies
sudo apt install -f

3.2 Fedora/RHEL-based Distros#

Download the .rpm package and install using DNF:

wget https://github.com/rgburke/grv/releases/download/vX.X.X/grv-X.X.X-1.x86_64.rpm
sudo dnf install grv-X.X.X-1.x86_64.rpm

3.3 Arch Linux#

GRV is available in the Arch User Repository (AUR). Install it using an AUR helper like yay:

yay -S grv

3.4 Compile from Source#

If no pre-built package exists for your distro, compile GRV from source:

# Install Go (Debian/Ubuntu example)
sudo apt install golang-go build-essential
 
# Set Go environment variables (add to ~/.bashrc for persistence)
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin
 
# Clone the GRV repository
git clone https://github.com/rgburke/grv.git
cd grv
 
# Build and install GRV
make install

Verify installation with grv --version.

4. Getting Started with GRV#

Once installed, using GRV is straightforward. Here’s how to launch and navigate the interface:

4.1 Launch GRV#

Navigate to any Git repository and run:

grv

You can also launch GRV from outside a repository by specifying the repo path:

grv --repo /path/to/your/git/repo

4.2 Interface Overview#

GRV’s interface is divided into three main panels:

• Top Bar: Displays the repository path, current branch, and commit stats (ahead/behind remote).
• Main Panel: Shows the active view (commits, branches, stashes, etc.). For commits, it includes a visual graph of branch history.
• Detail Panel: Shows detailed information about the selected object (e.g., full commit message, author details, or diff).

4.3 Basic Navigation#

GRV uses keyboard shortcuts for navigation. Here are the most essential ones:

5. Core Functionalities in Depth#

Let’s dive into GRV’s most powerful features and how to use them effectively.

5.1 Commit History Exploration#

The default view in GRV is the commit list, which includes:

• A visual graph of branch merges and splits.
• Commit SHA, author name, date, and truncated message.

To explore commits:

1. Use arrow keys to navigate to a commit.
2. Press d to view the diff between the commit and its parent.
3. Press Enter to expand the full commit message and author details.
4. Use Ctrl+Left/Right to switch between parent commits of a merge.

5.2 Branch Management#

Switch to Branch View with b to manage local and remote branches:

• Local Branches: Highlighted in green.
• Remote Branches: Displayed with the remote name (e.g., origin/main).

Key actions in Branch View:

• Press o to checkout the selected branch.
• Press D to delete a local branch (confirm with y).
• Press r to fetch updates from the remote.

5.3 Stash View#

Access your stashes with s:

• Each stash entry shows the stash message, date, and author.
• Press a to apply the selected stash.
• Press d to drop the selected stash (permanently delete it).
• Press p to pop the stash (apply and delete it).

5.4 Tag View#

Switch to Tag View with t to browse repository tags:

• Select a tag to jump to its associated commit.
• Press d to view the diff between the tagged commit and its parent.

5.5 Search and Filter#

GRV’s search functionality lets you quickly find specific objects:

1. Press / to open the search bar.
2. Type your query (e.g., fix bug to find commits with "fix bug" in the message).
3. Use n/p to navigate through matches.

For advanced filtering, use the command bar (press : to open it):

• Filter by author: :filter author:"John Doe"
• Filter by date range: :filter date:"2023-01-01..2023-12-31"
• Filter by branch: :filter branch:"main"

5.6 Diff Viewing#

GRV lets you view diffs directly in the terminal:

• For commits: Press d to see the diff between the selected commit and its parent.
• For stashes: Press d to see the changes stored in the stash.
• Use Arrow Keys to navigate through the diff, and q to exit the diff view.

6. Customizing GRV#

GRV is highly customizable via its configuration file. The default config is located at /etc/grv/config, but you should create a user-specific config at ~/.grv/config to avoid overwriting system-wide settings.

6.1 Creating a User Config#

Copy the default config to your home directory:

mkdir -p ~/.grv
cp /etc/grv/config ~/.grv/config

6.2 Customizing Key Bindings#

Edit ~/.grv/config to modify key bindings. For example, to change the "checkout branch" shortcut from o to c:

[bindings branchList]
checkout = c

6.3 Theme Customization#

GRV supports theme customization via style sections. For example, change the commit message color to yellow:

[style commitList.message]
color = yellow
 
# Change branch name color to blue in Branch View
[style branchList.branchName]
color = blue

You can use standard terminal colors: black, red, green, yellow, blue, magenta, cyan, white, or their bright variants (e.g., brightred).

6.4 Modifying Interface Layout#

Adjust the default view or panel sizes in the config. For example, set the default view to Branch View:

[view branchList]
default = true

7. Tips and Tricks for Efficient Use#

Here are some pro tips to maximize your productivity with GRV:

1. Launch GRV from Anywhere: Use grv --repo /path/to/repo to open a repository without navigating to it.
2. Sort Commits: Press : to open the command bar and type :sort date desc to sort commits by newest first, or :sort author asc to sort by author name.
3. Export Commit Info: Use :export /path/to/file.txt to export the current list of commits to a text file.
4. Debug Issues: Launch GRV with grv --log-level debug to generate detailed logs for troubleshooting.
5. Quick Reflog Access: Press r to switch to Reflog View, which shows all recent HEAD changes (useful for recovering lost commits).

8. Pros and Cons of GRV#

Before adopting GRV, consider these advantages and limitations:

Pros#

• Lightweight: No GUI dependencies, making it ideal for remote servers or low-resource systems.
• Intuitive Interface: Balances power with ease of use, even for intermediate Git users.
