compile_wasuro.sh

Pulls the Wasuro WASM runtime Pascal sources into the build tree.

Overview

compile_wasuro.sh fetches the Wasuro WebAssembly runtime from its Git repository using a sparse checkout (only the src/wasm subtree) and copies the Pascal source files into the local wasuro/ directory. This makes the Wasuro units available to the FPC compiler via -Fu include paths during compile_sources.sh.

Prerequisites

• git must be available and able to reach https://gitea.spexeah.com/Spexeah/Wasuro.git.
• The find and cp utilities must be available.

Inputs

Source	Description
Wasuro Git repository	Cloned (sparse, depth 1) from the develop branch.

Outputs

File	Description
wasuro/*.pas	Pascal source files for the WASM runtime, ready for inclusion in the FPC build.

Behavior

1. Cache check: If .pas files already exist in wasuro/, the script prints a message and exits immediately, skipping the network fetch.
2. Sparse clone: Clones the Wasuro repository into /tmp/wasuro with --depth 1, --filter=blob:none, and --sparse, then sets the sparse-checkout to src/wasm.
3. Copy: Copies the contents of the cloned src/wasm/ directory into wasuro/.
4. Cleanup: Removes the temporary clone from /tmp.
5. Reports the number of Pascal files copied.

Notes

• The sparse checkout minimizes download size by fetching only the src/wasm subtree.
• Once wasuro/ is populated, subsequent builds reuse the cached files without re-cloning. To force a fresh pull, delete the wasuro/ directory.
• The script uses set -e, so any failure (network error, git error) aborts the build.
