changed
changed to typed enum by genenum (https://github.com/kasworld/genenum)
tokentype
objecttype
precedence
change builtin function init
interpreter/evaluator/builtin_init.go
change parse function init
interpreter/parser/parser.go
prefixParseFns
infixParseFns
postfixParseFns
add repl from waig_code
add runmon for runfile, runstring with env
update nonkey, run 1 line ,run file, repl
add autoload arg
add global data package builtinfunctions, pragmas
change some map to slice for performance

enum/tokentype/attrib.go
Token2Precedences
add "I" to interface name
split asti interface package
change version handle (use https://github.com/kasworld/version)
update build script
update build version, args handle
add tokentype.attrib
change switch by operator string to tokentype
add NodeI(token.Token) to object.Error for source code line, posinline
TODO
replace ';' with '\n' or '\r'
del method call (tokentype PERIOD .) implement incomplete
If the implementation is hard to explain, it's a bad idea.
del redundant function define (tokentype DEFINE_FUNCTION function)
There should be one--and preferably only one--obvious way to do it.
del redundant ternary operator( tokentype QUESTION "? :" )
del indentifier composite char ( ? . % )
identifier start char must letter and _ , not digit, following letter,_ and digit
change "for" keyword to "while"
bug to fix
method call act oddly

Overview ¶
Monkey is a scripting language implemented in golang, based upon the book "Write an Interpreter in Go", written by Thorsten Ball.
This implementation adds a number of tweaks, improvements, and new features. For example we support file-based I/O, regular expressions, the ternary operator, and more.
For full details please consult the project homepage https://github.com/skx/monkey/
