nv-cli-ifif

• cli tool

• create a simple project ONLY USING if/else WITHIN a top-while-loop

• this is a simple version of 【nv-cli-many-block】 + 【nv-cli-state】 + 【nv-cli-ifelse】

• only support 2 layers

• only generate sync functions

• without using parser, just concat string

• suitable for small-scale(not-many-if-branch). if many if-branch(hundred * hundred: nv-cli-state is suitable

• nvlang has a ctx-dsl, it convert most code to while + if/else + a-matrix , this pkg for test it.

install

• npm install nv-cli-ifif -g
