Rescript-compiler: Can't use -bs-gen-tds switch

[antoine1fr]

When trying to generate .d.ts files as described in the documentation, I get the following error:

$ bsb -make-world -bs-gen-tds
/Users/antoine/Documents/work/bucklescript/hello/node_modules/bs-platform/bin/bsb.exe: unknown option '-bs-gen-tds'.
Usage : bsb.exe <bsb-options> -- <ninja_options>
For ninja options, try ninja -h 
ninja will be loaded either by just running `bsb.exe' or `bsb.exe .. -- ..`
It is always recommended to run ninja via bsb.exe 
Bsb options are:
  -color  forced color output
  -no-color  forced no color output
  -w  Watch mode
  -regen  (internal)Always regenerate build.ninja no matter bsconfig.json is changed or not (for debugging purpose)
  -clean-world  Clean all bs dependencies
  -clean  Clean only current project
  -make-world  Build all dependencies and itself 
  -init  Init sample project to get started
  -theme  The theme for project initialization, default is basic(https://github.com/bloomberg/bucklescript/tree/master/jscomp/bsb/templates)
  -themes  List all available themes
  -help  Display this list of options
  --help  Display this list of options
Error happened when running command /Users/antoine/Documents/work/bucklescript/hello/node_modules/bs-platform/bin/bsb.exe with args [ '-bs-gen-tds' ]

Is it normal?

You are passing -bs-gen-tds to bsb instead of bsc. If you are using the bsb build system then options for bsc go in the bsconfig.json file. :-)

[antoine1fr]

Ah ok, it totally makes sense now you say it. :)

[antoine1fr]

Where should I put it in the bsconfig.json file? The documentation is a bit lacking on this.

[OvermindDL1]

I always refer to https://github.com/bloomberg/bucklescript/blob/master/bsconfig.json for those, there is documentation somewhere but I cannot find where it is linked to from the manual?

Either way, you'll put it in to the "bsc-flags" list. :-)

seems already answered above

[mmiszy]

Is this still supported? When I try to use it I get the following error message:

…/lib/node_modules/bs-platform/lib/bsc.exe: unknown option '-bs-gen-tds'.

[bobzhang]

hi @mmiszy unfortunately, we removed it recently to reduce the maintenance overhead, (the generated .d.ts was never of production quality though)

[mmiszy]

@bobzhang do you know if there's currently anyone working on implementing this as a separate project? That would be useful.

Also: Do you accept PRs to the docs? -bs-gen-tds should be removed :)

[bobzhang]

Yes, PRs are welcome. There are some effort to make better integration with flow, but I am not sure when it will be production ready
