The `camelCase` function was not called properly

[xinbenlv]

• Expected Output: getSignedReplayProtectionPacketHash
• Actual Output: getSignedreplayprotectionPacketHash

To Reproduce:

Setup

git clone git@github.com:danfinlay/eip712-codegen.git
git checkout 73b411e83250755c2a1bd068d9f5eaf7b42be039
cd eip712-codegen
yarn install

Run

node cli.js --input sampleTypes.js --entryPoints ReplayProtection > ReplayProtection.sol

Root Cause

It seems the function camelCase is not being called properly.

For example

eip712-codegen/index.ts

Lines 5 to 9 in 73b411e

	function camelCase (str) {
	return str.toLowerCase().replace(/_(.)/g, function(match, group1) {
	return group1.toUpperCase();
	});
	}

• Input: camelCase("FooBar")
• Expected Output: fooBar
• Actual Output: foobar

It seems the root cause is that the camelCase above is meant to convert snake_case or SCREAMING_SNAKE_CASE into camelCase.

• Input: camelCase("foo_bar")

• Expected Output: fooBar

• Actual Output: fooBar (same as Expected Output)

• Input: camelCase("FOO_BAR")

• Expected Output: fooBar

• Actual Output: fooBar (same as Expected Output)

Therefore, I'd suggest make the following update:

1. Rename camelCase to snakeToCamelCase
2. Add assertion that the input is snake_case and SCREAMING_SNAKE_CASE
