[v5] Allow configuration of allowed_extenstions for the migrations

[roderik]

I'm using https://github.com/ethereum-ts/truffle-typechain-example to get everything into typescript but truffle migrate cannot find any migrations ending in .ts due to thus config option:

truffle/packages/truffle-migrate/index.js

Line 30 in 46fc7bd

options.allowed_extensions = options.allowed_extensions || /^\.(js|es6?)$/;

There is however no option to configure this in the truffle.js file.

Thanks @roderik for making Truffle Typescript-compatible , I hope it will be included in beta.2 👍

Yes thank you @roderik for getting the ball rolling. Right now we have our hands full prepping for Devcon, but shooting to have some of this included in beta.2 👍
