Fetch Tcl Source
Downloads Tcl release source tarballs from GitHub's codeload CDN
(https://codeload.github.com/tcltk/tcl/tar.gz/refs/tags/<tag>) and
extracts them to tmp/ so test suites, bytecode snippets, and reference
data are available without bundling Tcl source in the repository. Tarballs
are preferred over git clone because they are CDN-cached, smaller on
disk (no .git metadata), and easier on the upstream Tcl project.
Usage
bash .claude/skills/fetch-tcl-source/fetch_tcl_source.sh <version|all|status>
Commands
| Command | What it does |
|---|
84 or 8.4 | Fetch Tcl 8.4.20 source |
85 or 8.5 | Fetch Tcl 8.5.19 source |
86 or 8.6 | Fetch Tcl 8.6.16 source |
90 or 9.0 | Fetch Tcl 9.0.3 source |
all | Fetch all four versions |
status | Show which versions are present in tmp/ |
What it provides
After fetching, the following directories are available:
| Directory | Key contents |
|---|
tmp/tcl8.4.20/tests/ | Tcl 8.4 test suite (for reference capture) |
tmp/tcl8.5.19/tests/ | Tcl 8.5 test suite |
tmp/tcl8.6.16/tests/ | Tcl 8.6 test suite |
tmp/tcl9.0.3/tests/ | Tcl 9.0 test suite (primary reference) |
Each source tree also contains generic/, library/, doc/, and build files.
When to use
- At the start of a cloud session that needs Tcl test files
- Before running
scripts/capture/test_results.sh
- Before running
scripts/capture/bytecode.sh
- When investigating Tcl test suite behaviour across versions
Notes
tmp/ is gitignored — downloads are local only- Idempotent: re-running skips existing directories
- Downloads from
codeload.github.com with retry logic (4 attempts,
exponential backoff)
- Version numbers are hardcoded; update
fetch_tcl_source.sh when new
patch releases come out
