CallbackEditor by MTP3
edit callbacks without necessarily having to deal with terrible string manipulation directly™
CallbackEditor.prototype
disassemble(Function func): Object funcobj
Converts a function into a form that CallbackEditor can manipulate
reassemble(Object funcobj): Function func
Converts a funcobj generated by this.disassemble back to a new Function.
toFuncString(Object funcobj): String string
Returns a string that defines an anonymous arrow function with the funcobj's arguments and code.
funcToString(Function func): String string
Returns a string that defines an anonymous arrow function with the function's arguments and code.
Disassembles func and runs this.toFuncString with the resulting funcobj.
getCallString(String str, String args): String string
getCallString(String str, Array args): String string
Appends `args` to str, surrounded with parentheses. This creates a function call when converted to code.
`args` is treated like in 'new Function(args, code)'.
! Actual functions that I expect people to call.
prepend(Function func, String string): Function func
Prepends an arbitrary string to the beginning of the function.
Automatically appends a semicolon during concatenation.
append(Function func, String string): Function func
Appends an arbitrary string to the end of the function.
Automatically prepends a semicolon during concatenation.
callBefore(Function func, String funcref, String args): Function func
callBefore(Function func, String funcref, Array args): Function func
Prepends a function call to the beginning of `func`. Does not overwrite the original reference.
`funcref` is expected to be a path to the function accessible from the calling function.
`args` is treated like in 'new Function(args, code)'.
callAfter(Function func, String funcref, String args): Function func
callAfter(Function func, String funcref, Array args): Function func
Appends a function call to the end of `func`. Does not overwrite the original reference.
`funcref` is expected to be a path to the Function variable accessible from the calling function.
`args` is treated like in 'new Function(args, code)'.
runBefore(Function func, Function func2, String args): Function func
runBefore(Function func, Function func2, Array args): Function func
Prepends a copy of `func2` to the beginning of `func`. Does not overwrite the original reference.
`func2` inherits `func`'s scope.
`args` is treated like in 'new Function(args, code)'.
runAfter(Function func, Function func2, String args): Function func
runAfter(Function func, Function func2, Array args): Function func
Appends a copy of `func2` to the end of `func`. Does not overwrite the original reference.
`func2` inherits `func`'s scope.
`args` is treated like in 'new Function(args, code)'.
