Get all events from contracts

Get all events from contracts:	
	
	find . -type f -name '*.sol' ! -path '*node_modules/*' -print0 | xargs -0 sed -z "s/\/\/[^\n]*\n//g" | awk '/event/,/;/' | sed "s/[[:space:]]+event/event/" | sed -z "s/\n[\t ]*//g" | sed -z "s/;/;\n/g" | egrep "^event "
	
Get all event selectors from contracts:	
	
	find . -type f -name '*.sol' ! -path '*node_modules/*' -print0 | xargs -0 sed -z "s/\/\/[^\n]*\n//g" | awk '/event/,/;/' | sed "s/[[:space:]]+event/event/" | sed -z "s/\n[\t ]*//g" | sed -z "s/;/;\n/g" | egrep "^event " | sed "s/ indexed / /g" | sed -E "s/(address|u*int[0-9]+|bytes[0-9]*|bool|string)(\[\])* [^,\)]+/\1/g" | sed "s/event //" | sed -r "s/\s+//g"
	
NodeJS Script to compute topic hash:	
	
	const keccak256 = require('keccak256')
	console.log("0x" + keccak256('Transfer(address,address,uint256)').toString('hex'))
	...

Extracting all function complete declarations:
    find . -type f -name '*.sol' ! -path '*node_modules/*' -print0 | xargs -0 sed -z "s/\/\/[^\n]*\n//g" | awk '/function/,/{/' | awk '/function/,/;/' | sed "s/[[:space:]]+function/function/" | sed -z "s/\n[\t ]*//g" | sed -z "s/{/\n/g" | sed -z "s/;/\n/g" | egrep --text "^function "


Extracting all function names and corresponding contracts:
    egrep -rInH --include "*.sol" --exclude-dir=node_modules "^\W*function " | sed -r "s/(sol:[0-9]+):.*function /\1\t/g" | sed -r "s/\(+.*$//g"

Extracting all function signatures:
    find . -type f -name '*.sol' ! -path '*node_modules/*' -print0 | xargs -0 sed -z "s/\/\/[^\n]*\n//g" | awk '/function/,/{/' | awk '/function/,/;/' | sed "s/[[:space:]]+function/function/" | sed -z "s/\n[\t ]*//g" | sed -z "s/{/\n/g" | sed -z "s/;/\n/g" | egrep --text "^function " | egrep --text " (public|external) " | sed -E "s/(address|u*int[0-9]+|bytes[0-9]*|bool|string)(\[[0-9]*\])* [^,\)]+/\1/g" | sed "s/function //" | sed -r "s/ (public|external).*$//" | sed -r "s/\s+//g"
