`cargo fullstack` issues on Windows

[XBagon]

After following the instruction to the point where I used cargo fullstack I encountered this:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error { kind: NotFound, message: "program not found" }', .cargo/bin/fullstack.rs:17:10

I found out the problem probably has to do something with this:

〉which yarn
╭───┬──────┬──────────────────────────────────┬──────────╮
│ # │ arg  │               path               │ built-in │
├───┼──────┼──────────────────────────────────┼──────────┤
│ 0 │ yarn │ C:\Program Files\nodejs\yarn.CMD │ false    │
╰───┴──────┴──────────────────────────────────┴──────────╯

After some research I found some fitting issues.. #issuecomment-368300622 https://github.com/rust-lang/rust/issues/94743

For now the only idea I have to fix this, would be some Windows specific code to check for .CMD or maybe use which, which should support that?

This problem can be easily fixed by adding the .cmd extension. In addition to that, the yarn install location has to be added to the PATH environment variable.

#[cfg(windows)]
pub const YARN: &'static str = "yarn.cmd";

#[cfg(not(windows))]
pub const YARN: &'static str = "yarn";

Command::new(YARN)

Another problem is that Command::new("..").arg("fullstack") calls cargo tsync instead of tsync -i .. -o ... It's probably a cargo bug because calling the .exe directly works fine and gives expected results.

One way to fix this is to change the [[bin]] section in Cargo.toml

[[bin]]
name = "tsync"
path = ".cargo/bin/tsync.rs"

The problem with tsync is that when yarn is invoked from cargo tsync, the PATH has more stuff on it and prioritizes the wrong binary named "tsync":

C:\code\my-create-rust-app\.cargo\.build\debug\deps\tsync.exe  // wrong one, not normally on PATH
C:\code\my-create-rust-app\.cargo\.build\debug\tsync.exe       // wrong one, not normally on PATH
C:\Users\lynn\.cargo\bin\tsync.exe                             // right one

(I got this by modifying the yarn script in package.json to "tsync": "where tsync && tsync -i ...")

So instead of yarn actually calling tsync, it calls cargo tsync again, recursing until it gets confused and dies:

Running `yarn tsync` in `$project_dir/frontend/`...
yarn run v1.22.15
$ tsync -i ../backend -o ./src/types/rust.d.ts
Running `yarn tsync` in `$project_dir/frontend/`...
$ tsync -i ../backend -o ./src/types/rust.d.ts
Running `yarn tsync` in `$project_dir/frontend/`...
$ tsync -i ../backend -o ./src/types/rust.d.ts
Running `yarn tsync` in `$project_dir/frontend/`...
$ tsync -i ../backend -o ./src/types/rust.d.ts
Running `yarn tsync` in `$project_dir/frontend/`...
...

I can't think of a good fix. Maybe we can call %USERPROFILE%\.cargo\bin\tsync explicitly somehow?

The fix @mayhemdot seems to hint at is to rename the wrapper under [[bin]] to something else (like "teesync" 😄):

  [[bin]]
- name = "tsync"
+ name = "teesync"
  path = ".cargo/bin/tsync.rs"

Now delete .cargo\.build\debug\deps\tsync.exe and .cargo\.build\debug\tsync.exe, and run cargo run --bin teesync instead of cargo tsync.
