Usage

First Run

On first run, GiTime creates a configuration file at:

• Linux/Mac: ~/.gitime/config.json

Your git user email is auto-detected from git config user.email.

Add Repositories

Add repositories using absolute or relative paths:

# Absolute path
gitime --add-repo C:\repos\my-project

# Relative path
cd C:\repos
gitime --add-repo .\my-project

# Current directory
cd C:\repos\my-project
gitime --add-repo .

All paths are converted to absolute paths and stored in the configuration.

List Configured Repositories

gitime --list-repos

Show Configuration

gitime --show-config

Notes:

• Uses Norwegian ISO 8601 week numbering (weeks start Monday, Week 1 = first week with Thursday)
• Dates displayed in d/M/yy format (e.g., 3/2/26 for February 3rd, 2026)
• Always shows Mon-Fri, includes Sat/Sun only if commits exist on those days
• "Lines" column = total change volume (additions + deletions + modifications)
• Multiple weeks show separate tables with an overall total at the end
• Verbose mode shows ALL commits in chronological order (oldest first)
• Verbose mode shows up to 5 commits per repo, then "... (N more commits)"

Remove Repository

Remove repositories using absolute or relative paths:

gitime --remove-repo C:\repos\my-project
# or
gitime --remove-repo .\my-project

Configuration File

The configuration file is automatically created in your user profile:

• Windows: %APPDATA%\.gitime\config.json (typically C:\Users\YourName\AppData\Roaming\.gitime\config.json)
• Linux/Mac: ~/.gitime/config.json

Example configuration:

{
  "Repositories": [
    "C:\\repos\\project1",
    "C:\\repos\\project2"
  ],
  "AuthorEmails": [
    "your.email@example.com",
    "another.email@example.com"
  ],
  "DefaultLookbackDays": 30,
  "AzureTenantId": "your-tenant-id",
  "AzureClientId": "your-client-id"
}

You can manually edit this file to:

• Add multiple author emails (useful if you commit with different emails)
• Modify the list of repositories
• Change the default lookback period
• Configure calendar integration (see below)

Calendar Integration

GiTime can show your Microsoft Teams/Outlook meetings alongside your commits!

Setup

1. Create Azure AD app registration - See CALENDAR_SETUP.md for detailed instructions
2. Add to config - Add AzureTenantId and AzureClientId to your config.json
3. First run - GiTime will prompt you to sign in via browser (one-time setup)
4. Done! - Meetings will now appear in your reports

Note: Calendar integration is optional. If not configured, GiTime works normally showing only git commits.

Command Reference

Output Format

Week Numbering

GiTime uses ISO 8601 week numbering (Norwegian standard):

• Weeks start on Monday
• Week 1 is the week containing the first Thursday of the year
• Week numbers range from 1 to 52 (or 53 in some years)

Display Rules

• Weekdays: Monday-Friday always shown (even with 0 commits)
• Weekends: Saturday/Sunday only shown if commits exist on those days
• Multiple repos per day: Day name shown on first row, blank on subsequent rows
• Week totals: Sum shown at bottom of each week's table
• Overall totals: Grand total displayed after all weeks (when multiple weeks present)

Metrics Explained

• Commits: Number of commits made on that day in that repository
• Lines: Total line changes (additions + deletions + modifications combined)
  • Represents the total volume of code changes
  • Useful for estimating time/effort spent on different projects
