runcode v2.6 (2026/06/13)

What's new in v2.6

New auxiliary tools

• wait_for_server.py — polls a talk2stat server until it is ready to accept connections, eliminating the nohup startup race condition. Supports R, Python, Julia, and Matlab.
• runcode-Makefile.sample — sample Makefile encoding three best practices for nohup builds: restart server before each build, wait for readiness, send a sync barrier after the draft pass.
• consolidate.py — produces a self-contained copy of a runcode project with all cached outputs inlined into the .tex source, so the result compiles without talk2stat or any language runtime (e.g. for Overleaf or journal submission).

Checksum-based cache invalidation

Source files are now fingerprinted with MD5. A script is re-executed only when its source has changed or the output file is missing — no more unnecessary reruns, and no need to toggle the cache/run option manually.

Documentation

• runcode.tex / runcode.pdf: documentation rewritten directly in LaTeX (replacing the Emacs org→tex workflow); covers all new features.
• runcode_troubleshoot.tex: new entry for the nohup race-condition problem; updated cache-clearing section to reflect v2.5+ auto-invalidation.

Fixes

• Renamed wait_for_rserver.py → wait_for_server.py (works for all four languages).
• .ctan.sh: README is now generated from CTAN/README with the version placeholder correctly substituted.
