@ir-kit/codegen-core

Spec-agnostic codegen primitives shared by every native-SDK generator family — identifier transforms (pascal, camel, safeIdent, safeCaseName, softCamel, synthName, avoidLeadingDigit, escapeIfReserved), filesystem safety (assertSafeOutputDir), and project-name derivation (defaultProjectName). Pure functions, no spec dependencies.

Install

npm install @ir-kit/codegen-core

Zero runtime dependencies.

Identifier helpers

import {
  avoidLeadingDigit,
  camel,
  escapeIfReserved,
  pascal,
  safeCaseName,
  safeIdent,
  softCamel,
  synthName,
} from "@ir-kit/codegen-core";

pascal("first_name");     // "FirstName"
camel("first_name");      // "firstName"
softCamel("FirstName");   // "FirstName"  (preserves first-letter casing)
camel("FirstName");       // "firstName"  (lowercases first letter)
safeIdent("2024_release"); // "_2024Release"  (digit guard + pascal)
safeCaseName("4xx");      // "_4xx"
synthName("User", ["Address", "Street"]);   // "User_Address_Street"

avoidLeadingDigit("2value");                // "_2value"
escapeIfReserved("class", new Set(["class"]), (s) => `\`${s}\``);  // "`class`"

Filesystem helpers

import { assertSafeOutputDir, defaultProjectName } from "@ir-kit/codegen-core";

assertSafeOutputDir("./out/sdk");           // throws if outside CWD or in . / ..
defaultProjectName("./out/petstore-sdk");   // "petstore-sdk"

Status

0.1.0 — first release under the @ir-kit/* scope. Replaces the legacy @ahmedrowaihi/codegen-core (deprecated).
