Import PluginFunctionType?

[jablko]

Is there a way to import the PluginFunctionType type?

I tried to use it like so, to type a custom function method:
https://github.com/jablko/import-prepared-csv/blob/c44ed2c9047e2361e5631224e1d2a37e29e99161/Code.js#L431

... and import it like so:
https://github.com/jablko/import-prepared-csv/blob/c44ed2c9047e2361e5631224e1d2a37e29e99161/Code.js#L1

... however I get:

Code.js:1:44 - error TS2614: Module '"hyperformula"' has no exported member 'PluginFunctionType'.

This is a similar question, maybe. Thank you for HyperFormula!

Hi @jablko, thank you for reaching out!

Usually, extending from FunctionPlugin is enough to make the typechecking and other dev tooling work, as demonstrated in this example: https://hyperformula.handsontable.com/guide/custom-functions.html#add-a-simple-custom-function

However, if your setup requires PluginFunctionType, we could consider exposing it as a public API. Please describe your project setup and explain why you think PluginFunctionType should be exported.

Thank you @sequba! I did follow that example and extend FunctionPlugin however I named my "implementation method" parseDate() (it's named greet() in that simple custom function example).

If I named it differently, would it get typed? From looking at the implementation I don't understand how extending FunctionPlugin could automatically type either greet() or parseDate() because neither of those properties exist on the FunctionPlugin type (FunctionPlugin.greet/FunctionPlugin.parseDate)?

That's why I tried to import the PluginFunctionType type ...

Hi @jablko I had a quick chat with @sequba, extending FunctionPlugin is enough to register and type your custom functions. If ESLint (or another tool) still complains, you can disable or override the rule for that line or file.

@AMBudnik Thanks for looking into this! Extending FunctionPlugin isn't working in my own code --- my implementation method remains untyped. Can you please direct me to a working example? In the working demo section of the custom function docs if I hover over greet(), doubleRange() or their parameters I get any vs. e.g. ProcedureAst or InterpreterState ...
