[filepath:%s]格式化注入代码失败
Error message
[filepath:%s]格式化注入代码失败
What it means
After injecting, value.Format renders the modified AST back to formatted Go source; failure is wrapped as '[filepath:%s]格式化注入代码失败'. The injection happened, but go/format could not pretty-print the resulting tree — usually a malformed AST or an issue serializing positions/comments.

Solutions
- Read the wrapped format error (it names the offending node/token) and fix the injection template that produced it.
- Check for duplicate identifiers — if the generated function/import already exists in <filepath>, remove the old one or skip re-running the injection.
- Run gofmt on <filepath> after fixing, and verify the file compiles with go build.
Example fix
// before: injection created duplicate import import "gin-vue-admin/utils" import "gin-vue-admin/utils" // after: single import merged import "gin-vue-admin/utils"
Defensive patterns
Strategy: try-catch
Try / catch
if err != nil && strings.Contains(err.Error(), "格式化注入代码失败") {
// read wrapped go/format error, fix the injection template, then:
// exec: gofmt -w <filepath> && go build ./...
return fmt.Errorf("fix injection template output: %w", err)
} Prevention
- Ensure injection templates emit syntactically valid, non-duplicating Go.
- Skip already-injected code (check for existing identifiers before injecting).
- Run go build after each generation to catch formatting fallout immediately.
When it happens
Trigger: renderAutoCodeInjections when the injected snippet produces an AST that go/format rejects — e.g. injected code with invalid tokens, duplicate declarations, or the template emitted text that breaks Go syntax after merge.
Common situations: Custom injection templates generating syntactically invalid Go (bad imports, stray characters); injected identifier collides with an existing declaration in the file; format_node receiving comments positioned outside the file set.
