• How to write (simple) macro?

  - by krzysz00

  I need to write a macro (with-hooks (monster method who what) &body body) for a game I'm writing. Monster is a CLOS object, method and who are strings and what is a function (#' notation). The macroexpansion would be something to the effect of (add-hook monster method who what) ,@body (remove-hook monster method who) I have absolutely no idea how to write such a macro, and I would appreciate some help.

• Xcode/GCC predefined macro for target name?

  - by Justicle

  I was wondering if there is an Xcode or GCC preprocessor symbol for the target name of the application. For example if I'm building an application called "MonkeyChicken", is there a preprocessor symbol such that printf( __TARGET_NAME__ ) outputs: MonkeyChicken

• Updating target workbook - extracting data from source workbook

  - by Allan

  My question is as follows: I have given a workbook to multiple people. They have this workbook in a folder of their choice. The workbook name is the same for all people, but folder locations vary. Let's assume the common file name is MyData-1.xls. Now I have updated the workbook and want to give it to these people. However when they receive the new one (let's call it MyData-2.xls) I want specific parts of their data pulled from their file (MyData-1) and automatically put into the new one provided (MyData-2). The columns and cells to be copied/imported are identical for both workbooks. Let's assume I want to import cell data (values only) from MyData-1.xls, Sheet 1, cells B8 through C25 ... to ... the same location in the MyData-2.xls workbook. How can I specify in code (possibly attached to a macro driven import data now button) that I want this data brought into this new workbook. I have tried it at my own location by opening the two workbooks and using the copy/paste-special with links process. It works really well, but It seems to create a hard link between the two physical workbooks. I changed the name of the source workbook and it still worked. This makes me believe that there is a "hard link" between the tow and that this will not allow me to give the target (MyData-2.xls) workbook to others and have it find their source workbook.

• defining a simple implicit Arbitary

  - by FredOverflow

  I have a type Foo with a constructor that takes an Int. How do I define an implicit Arbitrary for Foo to be used with scalacheck? implicit def arbFoo: Arbitrary[Foo] = ??? I came up with the following solution, but it's a bit too "manual" and low-level for my taste: val fooGen = for (i <- Gen.choose(Int.MinValue, Int.MaxValue)) yield new Foo(i) implicit def arbFoo: Arbitrary[Foo] = Arbitrary(fooGen) Ideally, I would want a higher-order function where I just have to plug in an Int => Foo function. I managed to cut it down to: implicit def arbFoo = Arbitrary(Gen.resultOf((i: Int) => new Foo(i))) But I still feel like there has got to be a slightly simpler way.

• Initialising vals which might throw an exception

  - by Paul Butcher

  I need to initialise a set of vals, where the code to initialise them might throw an exception. I'd love to write: try { val x = ... generate x value ... val y = ... generate y value ... } catch { ... exception handling ... } ... use x and y ... But this (obviously) doesn't work because x and y aren't in scope outside of the try. It's easy to solve the problem by using mutable variables: var x: Whatever = _ var y: Whatever = _ try { x = ... generate x value ... y = ... generate y value ... } catch { ... exception handling ... } ... use x and y ... But that's not exactly very nice. It's also easy to solve the problem by duplicating the exception handling: val x = try { ... generate x value ... } catch { ... exception handling ... } val y = try { ... generate y value ... } catch { ... exception handling ... } ... use x and y ... But that involves duplicating the exception handling. There must be a "nice" way, but it's eluding me.

• Script/plugin to update web page (load next 25 comments) until page fully loaded

  - by Carl

  Brief summary: I need a script/plugin for Firefox that selects the "load next 25 comments" link at the bottom of a web page, until that link is no longer on the page. As you click that link - you get more comments - eventually all of them on the same page. See this web page for an example (there are 1,852 comments): http://www.cnn.com/2010/US/05/16/gulf.oil.spill/index.html#comment-50598247 I have a regular problem with CNN.com. I post comments there. People sometimes reply to them. I check my profile, and see the number of replies, but I can't read them there. I have to follow the link to the original article. The fist set of comments are at the bottom, with a 'load next 25' link at the bottom. There are often hundreds of comments, and sometimes a few thousand. There is no practical way for me to read the replies to my comments. If there's under around 300 hundred, I'll just click that link enough times to see what the replies to my comments are. I need a script/plugin to select that 'load next 25' link until that link is no longer present on the page. Then I could just search for my userid and read the responses.

• Macro and array crossing

  - by Thomas

  I am having a problem with a lisp macro. I would like to create a macro which generate a switch case according to an array. Here is the code to generate the switch-case: (defun split-elem(val) `(,(car val) ',(cdr val))) (defmacro generate-switch-case (var opts) `(case ,var ,(mapcar #'split-elem opts))) I can use it with a code like this: (generate-switch-case onevar ((a . A) (b . B))) But when I try to do something like this: (defparameter *operators* '((+ . OPERATOR-PLUS) (- . OPERATOR-MINUS) (/ . OPERATOR-DIVIDE) (= . OPERATOR-EQUAL) (* . OPERATOR-MULT))) (defmacro tokenize (data ops) (let ((sym (string->list data))) (mapcan (lambda (x) (generate-switch-case x ops)) sym))) (tokenize data *operators*) I got this error: *** - MAPCAR: A proper list must not end with OPS. But I don't understand why. When I print the type of ops I get SYMBOL I was expecting CONS, is it related? Also, for my function tokenize how many times the lambda is evaluated (or the macro expanded)?

• Putting together CSV Cells in Excel with a macro

  - by Eric Kinch

  So, I have a macro to export data into CSV format and it's working great (Code at the bottom). The problem is the data I am putting into it. When I put the data in question in it comes out Firstname,Lastname,username,password,description I'd like to change it so I get Firstname Lastname,Firstname,Lastname,username,password,description What I'd like to do is manipulate my existing macro so to accomplish this. I'm not so good at VBS so any input or a shove in the right direction would be fantastic. Thanks! Sub Make_CSV() Dim sFile As String Dim sPath As String Dim sLine As String Dim r As Integer Dim c As Integer r = 1 'Starting row of data sPath = "C:\CSVout\" sFile = "MyText_" & Format(Now, "YYYYMMDD_HHMMSS") & ".CSV" Close #1 Open sPath & sFile For Output As #1 Do Until IsEmpty(Range("A" & r)) 'You can also Do Until r = 17 (get the first 16 cells) sLine = "" c = 1 Do Until IsEmpty(Cells(1, c)) 'Number of Columns - You could use a FOR / NEXT loop instead sLine = sLine & """" & Replace(Cells(r, c), ";", ":") & """" & "," c = c + 1 Loop Print #1, Left(sLine, Len(sLine) - 1) 'Remove the trailing comma r = r + 1 Loop Close #1 End Sub

• Named parameters lead to inferior readability?

  - by Thomas Jung

  With named parameters like def f(x : Int = 1, y : Int = 2) = x * y your parameter names become part of the interface f(x=3) Now if you want to change the parameter names locally, you are forced to perserve the public name of the parameter: def f(x : Int = 1, y : Int = 2) = { val (a,b) = (x,y) a * b } If this a real problem? Is there a syntax to support this directly? Who do other languages handle this?

• OpenOffice Calc Macro: Run shell command and return output as result of custom function

  - by Mark

  I would like to write a custom OpenOffice function that runs a shell command and puts the result into the cell from which it was invoked. I have a basic macro working, but I can't find a way to capture the command's output. Function MyTest( c1 ) MyTest = Shell("bash -c "" echo hello "" ") End Function The above always returns 0. Looking at the documentation of the Shell command, I don't think it actually returns STDOUT. How would I capture the output so that I can return it in my function? Thanks!

• How to open a file quickly in visual studio .net

  - by binW

  In visual studio, we can open a file in a #Include statement by right clicking the filename in include statement and then clicking "Open Document". But sometimes, when I want to open a file, I don't remember where it was in the project or where has it been included. What I do is that I open any file, add a #include statement for that file, then right-click-Open Document to open the file and then remove the #include statement that I added just to open this file. Can someone plz tell me a more straight forward way of quickly opening a file without searching for it? I am using Visual Studio 2008

• My first Lisp macro; is it leaky?

  - by Tom Martin

  I've been working through Practical Common Lisp and as an exercise decided to write a macro to determine if a number is a multiple of another number: (defmacro multp (value factor) `(= (rem ,value ,factor) 0)) so that : (multp 40 10) evaluates to true whilst (multp 40 13) does not The question is does this macro leak in some way? Also is this "good" Lisp? Is there already an existing function/macro that I could have used?

• Liftweb Menu customization

  - by DataSurfer

  I want to create a menu that looks like: HOME | FOO | BAR | ABOUT | CONTACT How might I go about doing this? Here is what I have tried: <lift:Menu.builder ul:class="menu" li_item:class="current" /> and ul.menu li { display: inline; list-style-type: none; text-transform: uppercase; border-right: 1px solid white; padding-right: 5px; } li.current span { background: white; color: black; padding: 5px 5px 3px 5px; font-size: 11px; } li.current a, a:visited, a:link { color: white; padding: 5px 5px 3px 5px; font-size: 11px; } This gets close, but it doesn't look quite right. Also you end up with an extra line at the end. I want the lines to be the same height as the text. http://lh5.ggpht.com/_5DxlOp9F12k/S2aFQHfupzI/AAAAAAAAJiY/Ds0IpEyu78I/s800/menu.png

• Returning pointer to a certain value in a macro?

  - by Andrei Ciobanu

  Is it possible to write a macro that has a type and a value as its input parameters (MACRO(type,value)), and returns a valid pointer to a location that holds the submitted value. This macro should perform like the following function, but in a more generic manner: int *val_to_ptr(int val){ int *r = NULL; r = nm_malloc(sizeof(*r)); *r = val; return r; } Where nm_malloc() is a failsafe malloc. The Macro usage should be compatible with this usage: printf("%d",*MACRO(int,5)); Is it possible to achieve that ?
