pywayne-bin-gettool

name: pywayne-bin-gettool description: Fetch and install C++ tools/libraries from cpp_tools repository. Use when users need to download or clone third-party C++ libraries such as eigen, opencv, pcl, fmt. Use for building tools from source using CMake, installing tools with installation scripts, listing available tools, or managing cpp_tools repository URL. Triggered by requests to fetch, get, download, clone, or install C++ tools or libraries.

Pywayne Bin Gettool

Tool fetcher for C++ libraries from cpp_tools repository. Supports sparse/partial checkout, optional building with CMake, runtime dependency bundling for pybind modules, import verification, and installation scripts.

Quick Start

# List all supported tools
gettool -l

# Fetch a tool to default path (based on name_to_path_map.yaml)
gettool <tool_name>

# Fetch to specific path
gettool <tool_name> -t <target_path>

# Fetch and build (if buildable)
gettool <tool_name> -b

# Fetch and install (if installable)
gettool <tool_name> -i

Usage Patterns

1. List Available Tools

When user wants to see what tools are available:

gettool -l

2. Simple Fetch

Download tool source code to default path (determined by name_to_path_map.yaml in current directory):

gettool opencv
gettool eigen

3. Fetch with Custom Target

Download tool to a specific directory:

gettool opencv -t third_party/opencv
gettool eigen -t external/eigen

4. Build from Source

Build the tool using CMake. Requirements:

• Tool must be marked as buildable: true in name_to_path_map.yaml
• Tool must have a CMakeLists.txt file
• Build output (lib/) is copied to target directory
• The active Python interpreter is passed to CMake as PYTHON_EXECUTABLE
• If configured, runtime libraries are bundled into the target directory and the Python module import is verified

gettool apriltag_detection -b
gettool <tool_name> -b -t build/<tool_name>

5. Clean Copy (src + include only)

Fetch only src/ and include/ directories if they exist:

gettool eigen -c

6. Fetch and Install

After fetching, execute the tool's installation script (if configured):

gettool pcl -i
gettool pcl -i --global-install-flag true  # Use sudo make install

7. Fetch Specific Version

Check out a specific version/tag/branch (only works for tools that are submodules):

gettool fmt -v 9.1.0

8. Manage Repository URL

# Show current URL
gettool --get-url

# Set custom URL
gettool --set-url <URL>

# Reset to default URL
gettool --reset-url

Command Reference

Tool Types and Behavior

Submodule Tools

• Cloned as full independent repositories
• Support -v for version checkout
• Not built via CMake (use -b for source-level build if configured)

Non-Submodule Tools (Sparse Checkout)

• Fetched via git sparse-checkout from cpp_tools repo
• The fetcher should prefer git clone --sparse --filter=blob:none --depth 1 and fall back to plain sparse clone for compatibility
• Can be built with -b (requires buildable=true and CMakeLists.txt)
• Build output (lib/) copied to target directory

Default Path Mapping

When -t is not specified, the target path is determined by the path field in name_to_path_map.yaml relative to the current working directory.

Example: If opencv maps to third_party/opencv, running gettool opencv creates ./third_party/opencv.

Prerequisites

• Git
• CMake and a platform build tool (for -b flag)
• Appropriate C++ toolchain (for building)
• Write permissions for target directory

Network, Proxy, And Sandbox Troubleshooting

When gettool, git clone, curl, or git sparse-checkout fails against GitHub, do not assume the user's proxy is off. In Codex or another restricted sandbox, localhost TCP connections can fail even when the host machine proxy is running.

Use this diagnostic sequence:

git config --global --get http.proxy
git config --global --get https.proxy
lsof -nP -iTCP:7890 -sTCP:LISTEN
nc -vz 127.0.0.1 7890
curl -I --proxy http://127.0.0.1:7890 https://github.com --connect-timeout 5

Interpretation:

• If lsof shows a proxy process listening on *:7890, the proxy is probably enabled.
• If nc or curl fails with Operation not permitted or Couldn't connect to server inside the sandbox, rerun the same essential check with tool escalation.
• In Codex, use exec_command with sandbox_permissions: "require_escalated" and a short justification instead of asking the user to rerun it manually.
• Good escalation prefix rules are specific, for example ["nc", "-vz", "127.0.0.1", "7890"], ["curl", "-I", "--proxy", "http://127.0.0.1:7890"], or ["gettool", "<tool_name>"].
• If elevated nc/curl succeeds but sandboxed gettool fails, report it as a sandbox networking limitation, not as a proxy configuration problem.
• If elevated proxy checks fail too, then inspect proxy app settings, port number, and whether Git is configured to use the same proxy.
