# Odin Standards Standards for Odin code. Odin is underrepresented in training data — do not transplant Go/Rust/C error-handling patterns verbatim; reach for Odin constructs first. ## Idioms Prefer `or_else` when every failure path returns the same default: ```odin // Don't — all branches return the same fallback parse_env_int :: proc(key: string, default: int = 0) -> int { v, ok := os.lookup_env(key, context.temp_allocator) if !ok || v == "" { return default } x, ok2 := strconv.parse_int(strings.trim_space(v), 10) if !ok2 { return default } return x } // Do parse_env_int :: proc(key: string, default: int = 0) -> int { v := os.lookup_env(key, context.temp_allocator) or_else "" return strconv.parse_int(strings.trim_space(v), 10) or_else default } ``` Domain validation after parse is one line, not a rewrite: ```odin parse_env_f64_nonneg :: proc(key: string, default: f64 = 0) -> f64 { v := os.lookup_env(key, context.temp_allocator) or_else "" x := strconv.parse_f64(strings.trim_space(v)) or_else default return max(0, x) } ``` Use `or_return` to propagate errors instead of check-and-return blocks: ```odin // Don't data, err := os.read_entire_file_or_err(path) if err != nil { return nil, err } // Do data := os.read_entire_file_or_err(path) or_return ``` Use explicit `(value, ok)` checks only when failure modes differ (log, branch, or propagate differently per case). Mark file-local helpers and must-use results with attributes: `
