29-29: Update Zig Version in DocumentationThe version requirement update from
zig (0.13+)tozig (0.14)is correctly applied. This clearly informs users about the new minimum requirement and matches the PR objectives.solutions/zig/01-jm1/code/README.md (1)
29-29: Update Zig Version in DocumentationThe change to require
zig (0.14)instead of the previous version is accurately reflected here. It ensures consistency with the updated configuration across the project.starter_templates/zig/config.yml (1)
2-2: Updated Zig Version RequirementThe
required_executableattribute now correctly specifieszig (0.14), aligning with the overall upgrade objective. This change helps enforce the new minimum version for execution.solutions/zig/01-jm1/code/codecrafters.yml (1)
10-11: Updated Language Pack VersionChanging the language pack from
zig-0.13tozig-0.14ensures that the new version is consistently used in the Codecrafters environment. The inline comment clarifies the available version, which is a helpful touch.compiled_starters/zig/codecrafters.yml (1)
10-11: Consistent Zig Version ConfigurationThe update to
zig-0.14in thelanguage_packfield is correctly implemented and consistent with the other configuration files and documentation. This uniform update helps prevent version mismatches.solutions/zig/01-jm1/code/build.zig.zon (1)
2-3: Correct update for Zig 0.14 compatibilityThe changes to the package metadata are necessary for compatibility with Zig 0.14's package system. Using the
.codecrafters_redisreference instead of a string literal and adding the.fingerprintfield align with Zig 0.14's enhanced package identification requirements.compiled_starters/zig/build.zig.zon (1)
2-3: Properly updated package metadata for Zig 0.14These changes correctly adapt the package configuration to Zig 0.14's package system requirements. The consistent use of
.codecrafters_redisreference and identical.fingerprintvalue across build files ensures compatibility throughout the project.starter_templates/zig/code/build.zig.zon (1)
2-3: Consistent package metadata updatesThe package metadata changes match those in the other build.zig.zon files, ensuring consistent configuration across all project templates. This uniformity is important for maintaining compatibility with Zig 0.14 throughout the codebase.

4-4:❓ Verification inconclusive
Verify package versions
The specified minimum versions for xz (5.6) and curl (8.9) are quite high. Verify that Alpine 3.20 provides these versions to avoid build failures.
🏁 Script executed:
#!/bin/bash # Check what versions of xz and curl are available in Alpine 3.20 echo "Checking Alpine package repository for xz and curl versions..." docker run --rm alpine:3.20 apk info -v xz curlLength of output: 281
Manual Verification Required: Confirm Package Versions in Alpine 3.20
The automated script did not produce the expected output due to the missing Docker command, so please verify manually that Alpine 3.20 indeed provides at least xz version 5.6 and curl version 8.9 to prevent potential build failures. Specifically, ensure:
- xz is version 5.6 or newer.
- curl is version 8.9 or newer.
Once verified, adjust the version constraints in the Dockerfile if necessary.

Dockerfile uses experimental syntax
The
docker/dockerfile:1.7-labssyntax is an experimental feature that enables advanced capabilities like the--excludeflag. This is appropriate if the build environment supports it, but consider documenting this requirement.
🌐 Web query:
What is docker/dockerfile:1.7-labs syntax?💡 Result:
The
docker/dockerfile:1.7-labssyntax enables experimental Dockerfile features through Docker's labs channel, which provides early access to cutting-edge capabilities before they reach the stable release[2][4]. This syntax version introduces several advanced features:Key Experimental Features:
Enhanced
COPYCommand:
--parentsflag replicates source directory structure in the image (similar tocp --parents):COPY --parents ./nested/file.txt /destination/ # Creates /destination/nested/file.txt[1][5]--excludefilters files during copy operations:COPY --exclude=*.tmp ./src/ ./dest/[3][6]Advanced Variable Expansion:
- String manipulation directly in
${variable}substitutions:ARG VERSION=v2.1.0 RUN wget https://example.com/pkg/${VERSION#v}-linux.tar.gz # Resolves to 2.1.0-linux.tar.gz[3]Git Repository Integration:
- Direct cloning into images using
ADD:ADD [email protected]:user/repo.git /app/src[1][5]Path Pivot Syntax (
/./):
- Granular control over copied directory structure:
COPY --parents /out/./**/bin/ / # Copies only bin/ subdirectories[3]Usage Requirements:
# syntax=docker/dockerfile:1.7-labs FROM base-imageImportant Notes:
- Features might change incompatibly between versions[2]
- To access both 1.7 features and older labs capabilities, use
docker/dockerfile:1-labs[2]- Stable counterparts for these features may arrive in future non-labs releases like
docker/dockerfile:1.8[4]This syntax version is particularly useful for developers needing cutting-edge Docker capabilities, though production environments should prefer stable releases[2][4].

Experimental Dockerfile Syntax: Document Build Environment Requirements
- The Dockerfile in
dockerfiles/zig-0.14.Dockerfileuses the experimentaldocker/dockerfile:1.7-labsdirective. This syntax unlocks advanced features such as enhancedCOPYcapabilities (e.g., using the--excludeflag), advanced variable expansion, Git integration, and path pivot syntax.- These features require that the build environment supports BuildKit with labs channel capabilities. Please consider documenting this prerequisite in the project’s build documentation or README to ensure that all users are aware of the needed environmental configurations.

Fix invalid COPY flag in Dockerfile
The --exclude flag isn't supported in standard Docker COPY commands. Consider using a .dockerignore file or multi-stage builds to achieve the same result.

Fix invalid COPY flag in Dockerfile
The Dockerfile is using the experimental BuildKit syntax (# syntax=docker/dockerfile:1.7-labs), but even with this syntax, the COPY command does not support the --exclude flags. To exclude files like .git and README.md, please use a .dockerignore file and update the COPY command accordingly.

3-3: Added fingerprint for package identificationThe fingerprint
0xf806bb97907ce4a5has been added, which helps with package identification in Zig 0.14+. This is a good practice for package management.
12-12: Minimum Zig version updated to 0.14.0The minimum required Zig version has been updated from 0.11.0 to 0.14.0, which aligns with the PR objective of upgrading to Zig 0.14.
2-2:❓ Verification inconclusive
Check variable reference
.codecrafters_redisThe package name has been changed from a hardcoded string to a variable reference
.codecrafters_redis. Make sure this variable is defined somewhere in your build system, otherwise this will cause build failures.
🏁 Script executed:
#!/bin/bash # Check if .codecrafters_redis is defined in any Zig build files rg -l "codecrafters_redis" --type zigLength of output: 37
I'll run a more generic search (without restricting the file type) to verify if the variable reference
.codecrafters_redisis defined anywhere in the repository. This will help ensure we're not missing it due to file extension filtering.
🏁 Script executed:
#!/bin/bash # Re-run search across the repository for "codecrafters_redis" (not limiting to Zig file types) rg -l "codecrafters_redis" # Additionally, check for a definition pattern (e.g., a constant assignment) rg -l "const\s\+codecrafters_redis"Length of output: 1024
Action Required: Verify
.codecrafters_redisVariable DefinitionIn the file
solutions/zig/01-jm1/code/build.zig.zon(line 2), the package name is now referenced as.codecrafters_redisinstead of a hardcoded string. Automated searches did not reveal any corresponding definition (e.g., aconstassignment or similar binding) in the Zig build files. Please perform a manual check—if this variable isn’t defined or injected by your build configuration, it could lead to build failures.dockerfiles/zig-0.14.Dockerfile (3)
1-2: New Dockerfile for Zig 0.14 with modern syntaxGood use of the experimental BuildKit syntax and Alpine 3.20 as the base image for the new Zig 0.14 Dockerfile.
4-4: Package versions are pinned with minimumsGood practice using version constraints (
'xz>=5.6' 'curl>=8.9') to ensure minimum required versions while still allowing security updates.
7-10: Zig 0.14.0 installation looks goodThe Zig installation process correctly downloads, extracts, and places the binary in an appropriate location, then cleans up temporary files.
