Empty bindings.json file breaks build

[lucsoft]

• When deno_bindgen errors out it creates a empty bindings.json which should be fixed
• Marko should check before if the file is a valid json if not recreate it

@lucsoft I believe this was fixed in #28
Does this still happen if you use the CLI and Rust crate from the main branch?

[lucsoft]

@littledivy yes it still happens and I'm on main

[littledivy]

Ah okay. Just to confirm this is how you updated to main? :-)

# Cargo.toml
[dependencies]
deno_bindgen = { git = "https://github.com/littledivy/deno_bindgen", rev = "60a6f8a" }

deno install -n deno_bindgen -f -A --unstable https://raw.githubusercontent.com/littledivy/deno_bindgen/main/cli.ts

[lucsoft]

Can confirm this still happens
i think it's a race condition or something

i can't reproduce it consistently sadly

[littledivy]

Hmm I can't reproduce it.
There might be an issue with a bindings.json from previous version conflicting with main. Try rm bindings.json and see if you can reproduce it anymore.
Also a console output of the issue you're facing will be helpful.

i deleted it and it worked for some time but after some saves it breaks

and you get
called Result::unwrap() on an Err value: Error("EOF while parsing a value", line: 1, column: 0)rust-analyzermacro-error and the json file is empty

[lucsoft]

mostly when i make bigger changes like renaming the exported function

[littledivy]

I've added error handling for broken bindings.json. @lucsoft Can you still reproduce from latest main (update both crate and CLI)?
