lowk geen idee waarom ik dit stuur mr was wat aan het uittesten en beetje aan het kloten met iets van google en hij zei dit ineens dus idfk doe ermee wat je wilt de changes zijn wel goed in principe

This pull request introduces several major improvements to the codebase, focusing on modularizing the build process, improving reliability and testability, and enhancing CI/CD automation. The most important changes are grouped below:

Build Process Refactoring and Reliability Improvements:

  • Refactored the build() function in main.go into multiple smaller, focused functions (e.g., checkXcode, checkHomebrew, installDependencies, cloneRepository, configureBuild, buildGame, installGameToTemp, copyFilesToGameFolder), improving readability, maintainability, and error handling. Command execution now uses argument lists instead of shell strings for greater safety and reliability. (main.go [1] [2] [3] [4] [5] [6] [7] [8]
  • Improved Steam library folder detection by caching results and using concurrency-safe initialization, with associated regexes precompiled for performance. (main.go [1] [2]
  • Enhanced beta key validation logic by using precompiled regexes for better performance and clarity. (main.go main.goL210-R251)

Testing Enhancements:

  • Added new unit tests in main_test.go for findSteamLibraries, normalizeGameName, and validateGameName, increasing test coverage and ensuring correctness of utility functions. (main_test.go main_test.goR1-R172)
  • Added a benchmark test for findSteamLibraries in main_bench_test.go to monitor performance. (main_bench_test.go main_bench_test.goR1-R11)

Installer and Integrity Improvements:

  • Updated install.sh to download and verify a SHA256 checksum for the release artifact, ensuring users only install verified and untampered binaries. (install.sh install.shR42-R62)

Continuous Integration and Release Automation:

  • Added a GitHub Actions workflow .github/workflows/go-tests.yml to automatically run Go tests on pushes and pull requests to main, improving CI reliability. (.github/workflows/go-tests.yml .github/workflows/go-tests.ymlR1-R24)
  • Added .github/workflows/release.yml workflow to automate building, packaging, checksumming, and releasing the macOS app on pushes to main. (.github/workflows/release.yml .github/workflows/release.ymlR1-R49)

Dependency and Environment Management:

  • Changed the way temporary directories are created for repository cloning to use os.MkdirTemp for improved security and uniqueness, and ensures the base directory exists. (main.go [1] [2]
  • Updated the Go version in go.mod (downgraded from 1.26.1 to 1.24.3). (go.mod go.modL3-R3)

These changes collectively improve the maintainability, reliability, and security of the build tool, and establish a solid foundation for automated testing and releases.

Removed the ARE_WE_BUILDING_TO_A_APP global variable from main.go
as it was identified as dead code and was not being accessed anywhere
in the codebase. This improves code maintainability and readability.
Replace O(N) slice iteration with a O(1) map-based lookup to improve
deduplication efficiency when parsing Steam library folders.

⚡ Optimize Steam library membership check in findSteamLibraries
…124985451206947

🧹 remove unused global variable ARE_WE_BUILDING_TO_A_APP
Added a new file `main_test.go` with a table-driven test for the `validateGameName` function. The test cases cover valid game names, cases requiring normalization (casing, leading/trailing spaces), and invalid/empty inputs. Also adjusted the Go version in `go.mod` to 1.24.3 to match the local toolchain.
…ation

Refactored `checkSteamBetaRequirement` and `findSteamLibraries` to utilize global precompiled regex objects (`regexp.MustCompile`). This optimization replaces the costly implicit compilation happening on every invocation via `regexp.MatchString` or local `MustCompile` calls.

Benchmark testing demonstrated a ~12x speedup and a 100% reduction in memory allocations (from ~12.4 KB to 0) in the optimized logic paths.
Created `main_test.go` implementing comprehensive table-driven testing
for `shellQuote`, `normalizeGameName`, and `validateGameName` functions.
Tests cover happy paths, string variations (spaces, capitalization),
and various failure edge cases. Downgraded `go.mod` to match the local
development toolchain (Go 1.24.3) to allow for test execution.
Addresses arbitrary code execution vulnerability where a downloaded executable was run directly without integrity verification.

Risk: Allowed for supply chain attacks where a compromised GitHub release could execute malicious code on the user's machine.

Solution: Download a published .sha256 file and verify the zip archive using shasum before extracting and executing its contents.
Implement caching using sync.Once to avoid repetitive disk I/O and regex operations during Steam library lookup. Added a benchmark to verify the speedup. Returns a copy of the slice to protect the cache from caller mutation.
Extracted discrete steps from the monolithic `build()` function into 9 separate, well-named boolean functions (e.g. prepareTempRepoDir, checkXcode, installDependencies) to improve code readability and maintainability. The core execution flow in `build()` now elegantly chains these functions together.
- Created `main_test.go`
- Added table-driven tests for `normalizeGameName`
- Covered edge cases like mixed casing, whitespace, and empty strings
- Bumped go.mod version locally to match the build toolchain
The execSafe function previously concatenated strings into a single bash command executed via `bash -c`, which was vulnerable to command injection. This commit removes the `bash -c` pattern and updates `execSafe` to accept a slice of strings, passing arguments directly to `exec.Command`. It also introduces `execSafeDirEnv` to safely handle directory and environment configurations without relying on shell operators (`&&`, `export`, `cd`). All callers are updated to use this safer invocation method.

🔒 Fix command injection vulnerability in execSafe function
This caches the compilation of the `regexp.MustCompile` to avoid recompiling it every time `findSteamLibraries` is run.

Tested with a benchmark `BenchmarkFindSteamLibraries` with improvements in speed and memory allocations per operation.

Migrated away from using the user-controlled `--temp-repo-dir` flag value directly as the exact directory to clone into and delete during cleanup.

Instead, the `--temp-repo-dir` is now treated as a base directory where a unique temporary folder is created via `os.MkdirTemp`. This ensures that even if a user supplies a sensitive path (like `/` or `~`), the tool will only ever delete the random, freshly created subdirectory it explicitly owns, preventing unintended or malicious arbitrary file deletion.

This commit updates the `go` version specified in `go.mod` from `1.24.3` to `1.26.2`. It also brings in the Github actions test workflow and updates it to use `1.26.x` so it automatically picks up the latest patch version.

Correctly resolved remaining Git merge conflict markers in main.go that were causing syntax errors. Removed the extra markers and kept the optimal global precompiled regex vars as recommended. Verified the build runs cleanly via `go test ./...`.

@siemvk

- Change `.github/workflows/release.yml` trigger from `on: push` to `on: workflow_dispatch`.
- Add required `version` string input to specify the release tag.
- Update the "Create Release" step to use `github.event.inputs.version` instead of auto-generated `github.run_number` to prevent overwriting existing releases.
