From 33f562177f2f307a07a7e76ac65911bfcb73c610 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 20 Apr 2026 04:36:52 +0000 Subject: [PATCH 1/2] fix: code quality improvements across codebase MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bugs fixed: - classifyTarget: handle EvalSymlinks error instead of silently discarding it (fall back to raw source path) - validate: replace os.Exit inside RunE with ExitError type so Execute() controls the exit code — fixes testability and double-print - All unchecked fmt.Fprintf calls now use _, _ = (errcheck) Design: - loadConfig: use DefaultKnotfilePath (~/.dotfiles/Knotfile, $KNOT_DIR) instead of upward CWD walk (FindConfigFile) - config: add KnownOS, DefaultDir, DefaultKnotfilePath, KnotfileName, EnvKnotDir; document ~/path resolution asymmetry in Load - resolver: document that ShouldIgnore matches base name only Code quality: - Execute: set SilenceErrors=true, print errors once with "Error:" prefix - --config flag description now mentions $HOME/.dotfiles/Knotfile and KNOT_DIR - resolvePackageArgs: remove duplicate package-name validation (linker already validates); sort --all output alphabetically - validate: extract runValidation() for testability; use config.KnownOS; sort packages alphabetically; set SilenceUsage=true - Status: sort package names alphabetically before printing https://claude.ai/code/session_018s5iF8MKZAobUjAuR1AHJ4 --- cmd/root.go | 39 ++++++------ cmd/validate.go | 110 +++++++++++++++++----------------- internal/config/config.go | 44 ++++++++++++-- internal/linker/linker.go | 41 +++++++------ internal/resolver/resolver.go | 4 +- 5 files changed, 141 insertions(+), 97 deletions(-) diff --git a/cmd/root.go b/cmd/root.go index ce6a44b..bae6114 100644 --- a/cmd/root.go +++ b/cmd/root.go @@ -1,8 +1,10 @@ package cmd import ( + "errors" "fmt" "os" + "sort" "github.com/oxgrad/knot/internal/config" "github.com/spf13/cobra" @@ -13,6 +15,12 @@ var ( dryRun bool ) +// ExitError signals a specific OS exit code to Execute without triggering +// Cobra's error printer — the command is responsible for its own output. +type ExitError struct{ Code int } + +func (e *ExitError) Error() string { return "" } + var rootCmd = &cobra.Command{ Use: "knot", Short: "A lightweight, configurable dotfiles manager", @@ -23,14 +31,20 @@ based on your package definitions.`, // Execute runs the root command. func Execute() { + rootCmd.SilenceErrors = true // we handle printing to avoid Cobra's double-print if err := rootCmd.Execute();
