Kodrix — Current Session & Task Status

Last Sync: 2026-06-25

This file serves as a persistent record of the project's progress, ensuring context is preserved across AI sessions.

Current Milestone

Milestone 2: Language Intelligence & Native Toolchains

Completed Phases

Phase 3 — Core Native Environment (✅ Complete)

  • Native SWC Integration — compiled aarch64-linux-android binaries, patched with $ORIGIN RUNPATH logic for Next.js.
  • PtyBridge Symlinks — automated SWC symlink creation in node_modules after npm runs.
  • Multi-arch APK splits — arm64-v8a, armeabi-v7a, x86, x86_64.

Phase 4 — LSP Autocomplete (✅ Complete)

  • LSP Client Completion — prefix backtracking to prevent duplicate text insertion.
  • Syntax Highlighting — red/orange underlines driven by LSP diagnostics.
  • Multi-Tab Polish — suggestion cleanup on tab switch and closure.
  • Python LSP (pylsp) — zero-config background pip install with --no-deps workaround for ujson.
  • LSP path bug fix — corrected projDir to use projectsRoot so ProcessBuilder starts in the correct project directory.

Phase 5 — C/C++ Toolchain (✅ Complete — June 2026)

  • installCppToolchain() — on-demand download of Clang 21.1.8 + 6 dependency packages from Termux repositories.
  • Pure-Java XZ decompression — replaced broken tar -xJf (no system xz on Android) with org.tukaani:xz XZInputStream in Java, then tar -xf on the plain .tar.
  • Symlink-aware copyDirContents() — uses java.nio.file.Files.isSymbolicLink() + Files.createSymbolicLink() to handle windres → llvm-windres and other symlinks in the clang package.
  • Concurrency guard — isInstallingCpp synchronized flag prevents multiple parallel download coroutines.
  • tar exit-code check — throws with full output if extraction fails, ending the silent-failure loop.
  • BinaryManager.markToolInstalled("clang", "21.1.8") — skips VersionChecker (clangd can't self-exec in the Android sandbox); writes active version to prefs and rebuilds wrappers.
  • clangd LSP startup — full startNativeLsp flow for .c/.cpp after toolchain install completes.

Active Phase

Phase 6 — Polish & Stability

Pending / Next Up

  • Verify clangd autocomplete end-to-end after toolchain extraction completes on real hardware.
  • Add compile_commands.json generation support so clangd resolves project-specific include paths.
  • React Native support.
  • Flutter support.
