Fable: fable-compiler-js not working on Windows

[nojaf]

Description

I've tried to compile from F# with fable-compiler-js npm package.

Repro code

dotnet new classlib -o src -n App -lang F#

Changed Library.fs to

module App.Entry

printfn "no dotnet"

npx fable .\src\App.fsproj out

Expected

Output would be JavaScript file with that console.log statement.

Actual results

PS C:\temp\js-f> npx fable .\src\App.fsproj out

I know this stuff is alpha and I'm just letting you guys know what my findings are.
Low prio to solve this one, as I was merely to curious to check it out.

@ncave has been so kind to fix this :) @nojaf Can you please try with 1.0.0-alpha-009?

[alfonsogarciacaro]

Sorry! I made a mistake when publishing 🤦‍♂️ Please try with 1.0.0-alpha-010.

[nojaf]

Works with 010! Thanks @ncave and @alfonsogarciacaro.
I still have

Done in 2.19s.

But compilation does work. Each file in my fsproj was compiled individually.
I don't mind this however how does this related to fable-splitter?
Are the --options the same then?

[alfonsogarciacaro]

Yes, we should hide those logs somehow :) Maybe @ncave can make this line dependent on a "verbose" flag or something?

Because fable-compiler-js is pure JS, it doesn't rely on JS clients atm. Think of it for now as a fusion of fable-compiler and fable-splitter (though options are not the same). But yes, we're discussing right now how to restructure the repo to share more code between the different components and make everything more maintainable.

@alfonsogarciacaro I made it go away.
