This is my first time using an embedded language like this.
I'm trying to learn using lua as a script inside of MUSHclint, a sort of text-based role playing client.
In the client, if you just type the word help and hit enter, then it displays a help screen. If you type in "help then you get Character says, "Help"
In lua, I've made:
function hello ()
print("\"hello")
end
What I get is a "hello from the lua interpreter. Is there a way to make it "hello as if I typed it directly?
The end goal here is to create a random response when a person "CharacterX wants item" I know I'm way over my head, but please be nice to me.
In MUSH, you'd just do:
Send('"hello')
At least, that's if you're using the "Send to Script" option (rather than "Send to World"). MUSHClient has forums that are probably better suited to ask your questions regarding their product, though.

I am coding and there is a long string that i cant be asked to type out every time i need to. How could I set a shortcut?
example_coding.bla(bla.bla) *starts typing long string*
Then it recognises the start of my long string so gives me the option to press tab and auto insert the rest of it?
This is using LaTeX in Atom, but would be great if it could be for any coding language.
I know you're asking for how to create a command, but it sounds like what you really want is a snippet. Since you haven't provided any information about your use case, I can't tell you what to put in your snippets.cson, but the Flight Manual has all the necessary information.
My goal is to write a validation class for Rails that is capable of using an OCR recognised text from a business card and is able to detect string snippets and assign them to the correct attributes. I know this cannot be probably 100% perfect but I want to get as close as possible. Here is my approach so far:
I scan business cards via jquery's navigator.mediaDevices
I send the scanned image to a third party API Service, called OCRSpace (a gem is available here: https://github.com/suyesh/ocr_space)
I then get a unformatted array of recognised text snippets back, for example:
result = [['John Doe'], ['+49 160 123456'], ['Mainstr. 45a'], ['12345 Berlin'], ['CEO'], ['johndoe#business-website.de'], ['www.business-website.de']]
I then iterate through the array and do some checks, for example
Using the people library (https://github.com/mericson/people)
to split the name in firstname and lastname (additionally the title
or middlenames) Using the phonelib library
(https://github.com/daddyz/phonelib) to look up a valid phone number
and format it in an international string
Doing a basic regex check on the email address and store it
What I miss now is:
How can I find out what the name-string would possibly be? Right now I let the user choose it (in my example he defines "John Doe" as the name and then the library does the rest). I'm sure I would run into conflicts when using a regex as strings like "Main Street" would then also be recognized as a name?
How do I regex a combination of ZIP-Code and City name? I'm not a regex expert, do you know any good sources that would help? Couldn't find any so far except some regex-checkers in general.
In general: Do you like my approach or is this way too complicated? And do you know some best-practices that look better?
Don't consider this a full answer, but it was too much to make it a comment.
Your way of working seems Ok but I wouldn't use the OCR Service since there are other ways , Tesseract is the best known.
If you do and all the results are comparible presented it seems not too difficult since every piece of info has it's own characteristics.
You can identify the name part because it won't have numbers in it, the rest does, also you can expect to contain it "Mr." or "Mrs." or the such and not "Str.", "street" and so on. You could also use Google Maps to check for correct adresses, there are Ruby gems but have no experience with them.
Your people gem could also help.
You could guess all of this, present the results in you webpage and let the user confirm or adjust.
You could also RegExpr the post-city combination by looking fo a number and string combination in either order but you could also use a gem like ZipCodes to help.
I'm sorry, don't have the time now to test some Regular Expressions now and I don't publish code without testing.
Hope this was some help, success !
I want to do the following in expect, but I cannot find documentation that either shows how to do this or explains that it cannot be done.
I want to have a set or array of words, eg: "pig", "chicken", "house", "room"
I then want to run the same command for every word, eg: "delete $word"
I assume this has to be done in a foreach loop, but both Google and Bing refuse to show me any links that have both the word "expect" and "foreach" on the same page. Any pointer to the documentation will be greatly appreciated.
Expect is a Tcl extension, so the Tcl documentation is highly relevant: http://tcl.tk/man/tcl8.5/TclCmd/contents.htm
foreach word {pig chicken house room} {
delete $word
}
Introduction
I've been attempting to build this project for many weeks now, and trying multiple solutions that I can't get my head around. Let me describe the project a little. It's a text-based server, that players can login to (via telnet or a client), essentially like a MUD. They can then create and interact with 'objects', giving them 'verbs' and 'properties'.
The server is basically just a database of 'objects', each object has an ID, a name, a location (which is another object), a list of its contents (objects) and some other flags. Objects can have 'verbs' and 'properties'. Properties are just stored data (string, int, float, w/e). Verbs are methods/functions. Objects are interacted with using commands such as "put something in container". An old version of the server already exists, it's called LambdaMOO. I'm attempting to re-create it since it hasn't been updated in a very, very long time.
You can read more in-depth about how objects, verbs and properties should work at: http://bit.ly/17XIqjY
An Example
Let me describe what I'd like. Imagine we have an object. Object #256, it's called "Button". It has the property "count" along with all the default properties that are inherited from it's parent (i.e. 'description'). It has one "verb" on it, called "push". This verb contains this code:
this.count += 1;
this.description = "This button has been pushed " + this.count + " times.";
player.tell("You press the button and feel a chill run down your spine.");
When the player types 'push button' on the server, the 'push' verb will run and output
You press the button and feel a chill run down your spine.
If you then look at the button, you'll see it's updated description.
Note that player in the above script refers the object of the player executing the verb. tell is another verb, on the player object. However the tell verb has a flag saying it is executable from other verbs.
What language?
My main question is what languages can I use for the 'verbs'? I've tried using node.js and the 'vm' library. I've tried using C# to parse C#. I've tried using C# to parse JavaScript. The issue I keep getting is that I have no way of controlling the permissions of the verbs and properties. If I translate them to literal functions in JavaScript, I can't determine which object they are running on and what permissions it should have. If a user calls a function on another users object, I have no way of intercepting that call and stopping it if the permissions aren't correct. I'm not entirely fussed as to which language is used for the verb code it just needs to be "sandboxed". Properties need to be only readable/writeable when they are set to be so by the user, same with verbs. I imagine I could use a language with overloading (like PHP's __get, __set, __call).
I need to also be able to inject these variables into the verb: (mostly determined from the command typed, unless the verb is being called from another verb)
player (object) the player who typed the command
this (object) the object on which this verb was found
caller (object) this will be the same as ‘player’, unless another
verb calls the command in which case it is the object
containing that verb.
verb (string) the first word of the command
argstr (string) everything after the first word of the command
args (list of strings) a list of the words in ‘argstr’
dobjstr (string) the direct object string found during parsing
dobj (object) the direct object value found during matching
prepstr (string) the prepositional phrase found during parsing
iobjstr (string) the indirect object string
iobj (object) the indirect object value
I also need to be able to access any object from any other object (so long as the permissions work out).
// Object #128. Verb: multiply Prep: this none this Perms: +r +x
return (args[0] * args[1]);
// Object #256. Verb: square Prep: this none this Perms: +r +x
return #128:multiply(args[0], args[0]);
// Object #512. Verb: touch Prep: any any this Perms: +r
// Has a property (int) 'size' on it.
this.size = #256:square(this.size);
this.description = "It's a large button, it spans " + this.size + " metres.";
player:tell("You touch the button, it gets bigger.");
The user could then push button and the button object's size property would be squared.
Recommended Reading
I highly recommend you to read the document at http://bit.ly/17XIqjY for a more in-depth idea of how the system should work.
It is also recommended you read the following documents, as μMOO is based upon LambdaMOO and it’s methodology:

I take this question as asking for a language that could do what you need. That's what I'll try to answer.
First, this task is hopelessly unsuited to any mainstream or imperative language such as C# or Java. I wouldn't even think about it. Javascript is possible, but not what it's good at and nothing specific to recommend it.
Second, if you had the right skills, it would be an excellent opportunity to design an entirely new language and spend the next year or two getting it working. People really do that, but I don't recommend it unless you like that kind of masochistic experience. [I do.]
So my recommendation is that you widen your language experience until you find a match. Of the languages I know moderately well, Ruby is the best to try first. As soon as you said inject these variables into the verb you made me think of Ruby, because lots of Ruby software (including Rails) is built exactly like that. Forget Python, Perl and Javascript: I really don't think they will hack it.
Beyond Ruby you might contemplate Lua. I haven't used it much recently, and it may not suit, but it is widely used as a games scripting language.
Beyond that are the true functional languages. There is the most ancient of them all: Lisp. You can do absolutely anything in Lisp, including implementing the language you were looking for in the first place. Then there are Scala and Haskell, to name just two. They are mind-bending to learn, but well suited to the kind of problem you have.
Not much of an answer because it basically says: learn each of these languages in turn until you find one that works for you. [Happy to help further if I can. I have fond memories of Moo.]

can anyone suggest me how i can bulk insert this types of values to database by recognizing them with " .
i really need some efficient method to do it because my document is around 10,000 pages and i have to add all this to database and invoke in ios application..
Thanks in advance..
I know i will get my answer only here :)
I am not sure that this is possible for your docment and your situation, but what if you save this as text document and then parse it?
Parsing would be straightfoward - you should find first appearance of " and then you should fnd second appearance of ". Then get text between first and second ", and put into database.
