Summary of Changes
Hello @ReneWerner87, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request introduces a new Go-based formatter specifically designed to align benchmark results within the README.md file. It replaces a previous Python-based solution and integrates this new formatting capability into the project's Makefile for easy execution.
Highlights
- New Go-based Benchmark Formatter: A new Go program (
scripts/format_benchmarks.go) has been added. This script is designed to automatically format and align benchmark and memory allocation results found within Go code blocks in theREADME.mdfile, ensuring consistent presentation. - Dedicated
benchfmtMake Target: A newmake benchfmtcommand is now available. This target executes the newly introduced Go benchmark formatter, streamlining the process of keeping benchmark outputs consistently formatted in theREADME.md.

scripts/format_benchmarks.go (3)
11-16: Address error handling best practice.The error output in main should be handled properly according to static analysis.
func main() { if err := formatBenchmarks("README.md"); err != nil { - fmt.Fprintln(os.Stderr, err) + _, _ = fmt.Fprintln(os.Stderr, err) os.Exit(1) } }
44-44: Consider using a more specific regex pattern.The current regex
\S+matches any non-whitespace sequence, which may be overly broad for parsing benchmark output.- re := regexp.MustCompile(`\S+`) + re := regexp.MustCompile(`[^\s]+`)Or consider a more specific pattern if the benchmark format is well-defined:
re := regexp.MustCompile(`\w+[-\w.]*|\d+(?:\.\d+)?(?:ns|op|MB|allocs)/op`)
88-117: Consider extracting formatting logic into separate functions.The formatting logic is complex and could benefit from extraction for better readability and testability.
func formatBenchmarkLine(toks []string, widths []int) string { formatted := make([]string, len(toks)) for j, t := range toks { switch j { case 0: formatted[j] = padRight(t, widths[j]) case 1, 2, 4, 6: formatted[j] = padLeft(t, widths[j]) default: formatted[j] = t } } return strings.Join(formatted, " ") } func formatMemoryLine(toks []string, widths []int) string { formatted := make([]string, len(toks)) for j, t := range toks { switch j { case 0, 2: formatted[j] = padLeft(t, widths[j]) default: formatted[j] = t } } return strings.Join(formatted, " ") }

Learning: For future contributions to the `gofiber/recipes` repository, ensure that the tasks outlined in `.github/CONTRIBUTING.md` are incorporated, including creating a new directory without a "fiber" prefix, adding a `README.md` with Docusaurus metadata, and updating the overview by running `make generate`.

Timestamp: 2024-12-01T01:15:48.126Z
Learning: In the GoFiber `tableflip` recipe (`tableflip/main.go`), the implementation matches the upstream reference implementation. Future code suggestions should consider maintaining this alignment to ensure consistency.

scripts/format_benchmarks.go (3)
46-67: LGTM! Solid parsing logic with proper state management.The code correctly:
- Tracks Go code block boundaries
- Identifies benchmark and memory allocation lines
- Handles tab-to-space conversion
- Maintains proper indexing for later formatting
126-143: LGTM! Efficient column width calculation.The implementation correctly calculates maximum column widths across all entries, handling variable column counts properly.
145-157: LGTM! Clean and efficient padding functions.Both padding functions handle edge cases properly and use efficient string operations.
Makefile (2)
29-29: Good fix! Proper tab indentation in Makefile.The change from spaces to tab indentation follows Makefile conventions correctly.
31-34: LGTM! Well-integrated new target following project conventions.The new
benchfmttarget:
- Uses descriptive emoji and documentation comment
- Marked as
.PHONYcorrectly- Follows the same pattern as other targets
- Provides easy access to the new Go-based benchmark formatter
