create-release-tags

Overview

Automates Debian package version releases by updating debian/changelog and linglong.yaml (if present), generating change summaries from git log, and creating version commits.

When to Use

digraph when_to_use {
    "Need to release version?" [shape=diamond];
    "Debian project?" [shape=diamond];
    "Use this skill" [shape=box];
    "Wrong tool" [shape=box];

    "Need to release version?" -> "Debian project?" [label="yes"];
    "Debian project?" -> "Use this skill" [label="yes"];
    "Debian project?" -> "Wrong tool" [label="no"];
}

Use when:

• Releasing new version for Debian-based projects
• Preparing test releases (tag prepare-test)
• Bumping version numbers with changelog updates
• Projects with or without linglong.yaml

Trigger phrases:

• "tag release "
• "tag release" (auto-increment)
• "tag prepare-test "
• "release new version"
• "bump version"
• "update version"
• "prepare for release"
• "prepare for testing"

Do NOT use when:

• Projects without debian/changelog
• Creating git tags (this skill only commits changes)
• Non-Debian projects

Quick Reference

Implementation

Step 1: Detect Project Type

# Check required files
if [ ! -f debian/changelog ]; then
    echo "Error: Not a Debian project (debian/changelog not found)"
    exit 1
fi

# Check for linglong.yaml files
LINGLONG_FILES=$(find . -name "linglong.yaml" -type f)
HAS_LINGLONG=1
if [ -z "$LINGLONG_FILES" ]; then
    HAS_LINGLONG=0
fi

Step 2: Determine Target Version

Default behavior: If no version specified, auto-increment patch version (e.g., 6.5.26 → 6.5.27)

If version specified:

TARGET_VERSION="$1"  # e.g., 6.5.47

If auto-increment (no version specified):

# Extract current version from changelog
CURRENT_VERSION=$(head -1 debian/changelog | sed -n 's/.*(\(.*\)).*/\1/p')
# Extract and increment patch version (only increments patch: X.Y.Z → X.Y.Z+1)
MAJOR=$(echo $CURRENT_VERSION | cut -d. -f1)
MINOR=$(echo $CURRENT_VERSION | cut -d. -f2)
PATCH=$(echo $CURRENT_VERSION | cut -d. -f3)
TARGET_VERSION="${MAJOR}.${MINOR}.$((PATCH + 1))"

Step 3: Generate Change Summary

IMPORTANT: Get commits from current changelog version (NOT from git tags, as tags may not always be created).

# Extract date from first author line in changelog
# Format: "Mon, 05 Jan 2026 15:29:58 +0800"
# This finds the line starting with " -- " and extracts the date part
CURRENT_DATE=$(grep -m1 "^ -- " debian/changelog | sed 's/.*  //')

# Get commit titles since that date (note: two spaces before *)
if [ -n "$CURRENT_DATE" ]; then
    CHANGES=$(git log --since="${CURRENT_DATE}" --pretty=format:"  * %s")
else
    # Fallback: get recent commits if date extraction fails
    CHANGES=$(git log --pretty=format:"  * %s" -10)
fi

# If no changes, use generic message
if [ -z "$CHANGES" ]; then
    CHANGES="  * chore: bump version to ${TARGET_VERSION}"
fi

Step 4: Get Author Information

AUTHOR_NAME=$(git config user.name)
AUTHOR_EMAIL=$(git config user.email)

if [ -z "$AUTHOR_EMAIL" ]; then
    echo "Error: Git user.email not configured"
    echo "Please run: git config user.email 'your@email.com'"
    exit 1
fi

DATE_R=$(date -R)

Step 5: Get Package Name

PACKAGE_NAME=$(head -1 debian/changelog | sed -n 's/\([^ ]*\) .*/\1/p')

Step 6: Update debian/changelog

Create new entry at top of file:

${PACKAGE_NAME} (${TARGET_VERSION}) unstable; urgency=medium

${CHANGES}

 -- ${AUTHOR_NAME} <${AUTHOR_EMAIL}>  ${DATE_R}

<existing entries follow>

Example:

deepin-reader (6.5.47) unstable; urgency=medium

  * fix: correct .tx/config
  * chore: enhance service security
  * feat: add new feature

 -- Author Name <email@example.com>  Mon, 05 Jan 2026 15:29:58 +0800

deepin-reader (6.5.46) unstable; urgency=medium
...

Implementation:

# Read existing changelog
EXISTING=$(cat debian/changelog)

# Create new entry (note: two spaces before each * and author line)
NEW_ENTRY="${PACKAGE_NAME} (${TARGET_VERSION}) unstable; urgency=medium

${CHANGES}

 -- ${AUTHOR_NAME} <${AUTHOR_EMAIL}>  ${DATE_R}

"

# Write new content
echo "${NEW_ENTRY}${EXISTING}" > debian/changelog

Important formatting notes:

• Each change line starts with two spaces + *: * fix: something
• Author line starts with two spaces + --: -- Author <email>
• Double newline between version entries

Step 7: Update linglong.yaml (if exists)

For each linglong.yaml file:

• Update version field: X.Y.Z.N → X.Y.Z.N (update only first three parts)
• Keep last number unchanged

Example: version: 6.5.46.1 → version: 6.5.47.1

Implementation:

if [ $HAS_LINGLONG -eq 1 ]; then
    TARGET_VERSION_NO_PATCH=$(echo $TARGET_VERSION | cut -d. -f1-3)
    find . -name "linglong.yaml" -type f -exec sed -i "s/version: [0-9]\+\.[0-9]\+\.[0-9]\+\.[0-9]\+/version: ${TARGET_VERSION_NO_PATCH}.1/g" {} \;
fi

Step 8: Commit Changes

git add debian/changelog
if [ $HAS_LINGLONG -eq 1 ]; then
    git add $(find . -name "linglong.yaml" -type f)
fi

git commit -m "chore: update version to ${TARGET_VERSION}

- bump version to ${TARGET_VERSION}

Log : bump version to ${TARGET_VERSION}"

Commit message format:

• Line 1: chore: update version to <version> (lowercase)
• Empty line
• Bullet: - bump version to <version> (lowercase)
• Log prefix: Log: bump version to <version> (note space after colon)

Common Mistakes

Red Flags - STOP and Check

• Commit message doesn't follow exact format
• Using git tags instead of changelog for change summary
• linglong.yaml version changes all four parts
• Missing git user.email configuration
• debian/changelog doesn't exist
• Trying to create git tags (not supported)

If any red flag appears, STOP and review the implementation section above.
