[haskell-servant][haskell-yesod] Use table-based conversion for field name conversion (#16232)
* [haskell-servant][haskell-yesod] use table-based conversion for field name conversion

Current fieldLabelModifier implementation always produces uncapitalize
name, but it is inappropriate if the original JSON field name begins
with a capital letter.

Haskell Setup

  1. If you haven't already, install Stack
    • On POSIX systems, this is usually curl -sSL https://get.haskellstack.org/ | sh
  2. Install the yesod command line tool: stack install yesod-bin --install-ghc
  3. Build libraries: stack build

If you have trouble, refer to the Yesod Quickstart guide for additional detail.

Development

Start a development server with:

stack exec -- yesod devel

As your code changes, your site will be automatically recompiled and redeployed to localhost.

Tests

stack test --flag open-api-petstore:library-only --flag open-api-petstore:dev

(Because yesod devel passes the library-only and dev flags, matching those flags means you don't need to recompile between tests and development, and it disables optimization to speed up your test compile times).

Documentation

  • Read the Yesod Book online for free
  • Check Stackage for documentation on the packages in your LTS Haskell version, or search it using Hoogle. Tip: Your LTS version is in your stack.yaml file.
  • For local documentation, use:
    • stack haddock --open to generate Haddock documentation for your dependencies, and open that documentation in a browser
    • stack hoogle <function, module or type signature> to generate a Hoogle database and search for your query
  • The Yesod cookbook has sample code for various needs
