Philippe, thanks for the reply.
so i am been programming in Basic for over 38 years. my first computer had a version of basic hand-coded by bill gates, in the 1970's. yes, it is true that visual basic does require the use of an IDE but visual basic for application does have a interactive console. yes, i use print() and that works and only for people who cannot do edit-and-continue are doomed to be punished with just print(). not a very nice solution when i am trying to teach programming concepts to children. lol, i used to program using punch cards on an ibm mainframe, perhaps we should downgrade back to that, who needs keyboards anyway... since i first asked my question, and based on some posts and doing some research, edit-and-continue can in fact be done for Lua from the interactive console. it is much more then a crutch or convenience. anybody that has not tried it should not trivialize it. all the more so for Lua. Lua is designed to be a embedded solution, often used by non-programmers. for example, arrays indexes start from 1, not zero. you should take a look at the posts by Kevin T. Ryan. one example of what he wrote is: "You may want to try ZeroBrane Studio: >> http://notebook.kulchenko.com/zerobrane/live-coding-in-lua-bret-victor-style" after looking at the videos, let me know what you think. youtube has some great videos. look at the zues editor for Lua videos thanks and enjoy. > To: lua-l@lists.lua.org > From: PhiLho@GMX.net > Date: Fri, 22 Jun 2012 14:44:44 +0200 > Subject: Re: newbie: how to modify lua code while the program is running like visual basic > > On 21/06/2012 21:41, yoyomeltz yoyomeltz wrote: > > kevin, thanks you much. it does seem to offer what i wanted but the problem is i would be > > locked into an ide that does not seem to offer much else. > > > > there has to be a simple way to dynamically reload code as needed via a > > console/command.line or other simple solution. > > if visual basic from microsoft can do it and python can do it, then why should i be an > > issue for Lua. > > even visual basic 6.0 from 10 years ago can do that. > > > > it seems to me this such a feature is a pre-requisite for learning any language, espcially > > a lightweight scripting language. > > so does anybody have any other suggestions? > > Well, if I am not mistaken, VB is "locked into an IDE"... > I don't know for Python. > Debugging is often tied to an IDE anyway, unless you are using some command line debug > tool (but that's still a tool, often separate of the compiler / interpreter, no?). > > Eclipse (and probably other Java IDEs as well) allows such hot fix, changing code while > running and the program continue to run with this change. > Now, it has some limitations: if you change a method while debugging in it, Eclipse puts > the current program line pointer to the start of the method. > If you change deeply a class, eg. the visibility of a method, or a new method, it tells > you it can't do the hot fix and shows markers in the debug stack trace to show the code is > no longer synchronized. > > So it isn't a perfect feature for every language / IDE.
