AutoCAD Visual LISP / AutoLISP :: Appending Associative List
Jul 17, 2012
Here is the code snippet from my program, I am trying to build a associative list from two regular lists in the while loop. Does ""append " or "cons" only work for simple lists? Given attributeNameList attributeValTypeList which are always of the same length
(setq listCntr 0)
(while (<= listCntr (length attributeNameList))
(setq attrTagTypeAssnList (append attrTagTypeAssnList (list ((nth listCntr attributeNameList) (nth listCntr attributeValTypeList))) ))
(setq listCntr (1+ listCntr)
)
How can I dynamically build the association list.

I'm making a program that reads a property file that follows the format:
"key=value" for each line on the text file.
One specific line has the key "file" and the value is some file path that includes a space.file=C:/my folder/my file.txt
Now I can extract what the key and value is for any given line in the file.However, I want to put all of the data into an Associative List so that I will not need to keep opening the file each time I search for information. I've been using the cons function in order to create a dotted list, which is successful. However I have an issue when I add this dotted list to the end of my associative list.
Suppose I have a key and a value already stored inside variables. Below I have two lines of code, first the dotted list portion is printed, and works as expected. The second line adds that dotted list to the associative list:
(princ "Cons: ")(princ (cons key val)) (princ "") ;Prints (file . C:/my folder/my file.txt)(setq assocList (append assocList (cons key val))) ;Error message here.
The error that I receive says "; error: bad list: "C:/my folder/my file.txt"..Here is the change:
(setq assocList (append assocList (list (cons key val))))
Now, the dotted list is inserted properly and looks like this after printing the whole associative list: ((version . 1.0.1) (file . C:my foldermy file.txt))

I am adding tool palettes for our new CAD Standards and would like to set the support paths so the users don't have to.
I will need to set:
Support File Search Path
Dictionary
Plot Style
Color Book
Drawing Template
Sheet Set Template
Tool Palettes
[URL].......
[URL].........
[URL].........
[URL].........
[URL]...........
Basically I would like to append the paths for the new items, but not overwrite the variety of existing paths.
So I assume I need to read the current paths, read the new paths and append them to the current paths, then write them as updated paths? This is for about 30 users in 11 different offices and varying cad skills.
I can tweak existing LISP routines, but have never written one from scratch. Is there an "easy" way to accomplish this?

Id like to append a file with the following text...
(load "C:/ICT/GEBERIT/LSP/GEBERIT.LSP")
Quotation marks and all but how do i Handel them and the open and closed brackets using the following lisp example
(setq f(open "C:/ICT/AutoCAD_Architecture_suite_2012/LSP/acaddoc.lsp" "A"))(write-line "(load "C:/ICT/GEBERIT/LSP/GEBERIT.LSP")" f)(close f)

I have a list -
(setq List1 (list "Line A" "Line B" "Line C"))
I would like to add each item in an existing list to a new list -
(setq ListNew (list "This is some text" "This is more text"
the following is the part I can't figure out - it just adds the list to the list, not the individual items
(mapcar '(lambda (x) x) List1)))
I am looking for ListNew to be - (a list with 5 strings)
"This is some text"
"This is more text"
"Line A"
"Line B"
"Line C"

I have a list ("temp.dwg" "temp2.dwg") and would like to add the string "insert text here" into each item in the list resulting in ("insert text heretemp.dwg" "insert textheretemp2.dwg"). how would i go about doing that using LISP?

I have a list that contains data like this,
"Tree-01-08-AA5"
"Tree-04-12-QV"
"Tree-10-30-QS"
How would I go about sorting this list by AA5, QV, QS? I know how to use vl-sort and reverse, but I do not understand how I would go about this.

I need to modify the code below.
When I run the command and write the scale, I need to change the name of the scale and the ratio automatically. The ratio should always be in the format "1: #", also the name of the scale. Maybe assigning more variables with "setq", I do not know.
(defun c:test ()(setvar "cmdecho" 0)(setq name (getint "
Type the scale you need:"))(setq ratio (strcat "1:" "0.1"))(command "-SCALELISTEDIT" "Add" name ratio "Exit")(setvar "cmdecho" 1)(princ))

Here's one that I could use on that i can't figure out:
I have a list of a bunch of descriptions that looks like this:
("00.02.00" "CTD01 Mainframe PT1 (top)" "GD01")
What I am doing is grabbing the middle item and i need to break this up into 2 lines. So, my code below grabs the first 3 "words" in the second item in the list and puts them in a list, but I need to convert this back to a string.
(setq desc6a (list (car (read (strcat "(" (cadr input6) ")" )))(cadr (read (strcat "(" (cadr input6) ")" ))) (caddr (read (strcat "(" (cadr input6) ")" )))))
I tried a bunch of ways but can't get it

I've been experimenting with lists and I'm curious about the fastest / easiest way to get the next element from a list:
Currently my best shot is to wrap (member 2 '(1 2 3)) with: (car(cdr (member 2 '(1 2 3))))

I've created a list and want to subtract all the values within it from another variable, and assign it to a new variable. How do I do it?
Basically, I ask for ground level (assigned to variable G1), and then any number of depths beneath that (assign to list LVLLIST), and I want to return the value of the bottom point. So it's all the values in LVLLIST added together and subtracted from G1. And assign it to a new variable BASE.
For example,
G1 = 650.00
LVLLIST = (1.23 23.26 0.13 50.23)
(setq BASE (- G1 LVLLLIST))

In the example given I have two instances to show how unique the information can be.
I would like the left column of words to be some type of drop down or list so that the user does not have to type these for each line. I don't care if it's attribute, text, mtext, just whatever gets it done.

I have the following string of code, that I'll write in everyone's start-up suite. I'm able to retrieve a list of files I want to modify, for whatever reason. (One example, when plotting drawings with layouts, sometimes the shadeplot setting is wireframe, and not classic hidden, though it's been set up in our templates).
The huge question is, can I get a list of drawings to a variable in one drawing, and have access to that variable list, in the next drawing I open? I'll iron out the bugs on read-only statuses, or manipulating drawing states later.
(defun GetDrawings ()
(setq currentpath (getvar "dwgprefix"))
(command "pspace")
(setq DrawingList (dos_getfilem "Select a file" currentpath "Drawing files (*.dwg)|*.dwg|All files (*.*)|*.*||"))
(setq ListOfDrawings (cdr DrawingList))
(setq DrawingPath (nth 0 DrawingList))

I want to make a list of layers due to their index (order) in the "layers combo box" in the AutoCAD. I prepared this:
(defun c:ListLayers ( / a b)(setq a(list(cdr(assoc 2(tblnext "layer" T)))))(while(setq b(tblnext "layer")) (setq a(append a(list(cdr(assoc 2 b))))));while);end
But, It's not match with the order of layers.

How can I determine what was selected in the pop-up box and then using that for 1 of 2 things, either 1) Turn off the Edit Box for Hole Spacing if the selected option is 1(which would be value = "0" of the popup list) or 2) Making the portion where it confirms that the Hole Spacing Edit Box is filled out so that if the Pop-up List displays 1, it doesn't check the Hole Spacing Box. Below is the DCL and LISP that I'm currently using.
Here is my current DCL:
questions :dialog {label = "Information for Program";: row {: column {: boxed_radio_row {key = "Galv";label = "Galv Slot Required?";: radio_button {key = "Y"; label = "Yes"; value = "1";}: radio_button {key = "N"; label = "No";}}: boxed_radio_row {key = "Bevel";label = "Is Leg to Face

How can I sort an association list?
for example:
(setq lst '((1 . "s") (12 . "t") (-7 . "u") (0 . "v")))
should be sorted as:
((-7 . "u") (0 . "v") (1 . "s") (12 . "t"))
{ sort on: (car(assoc index lst)) value}

Is it possible to obtain a list of coordinates for view ports (with dxf codes or otherwise) similar to obtaining a list of (assoc 10) for polylines?
I'm aware I can get the center, width and height from the dxf codes, but what about for clipped view ports with irregular shapes?

how to work with safearrays so that I can modify a dynamic block property reporting tool that I found here on the forums. I’d like to take the following code and filter out the extraneous properties so that the user doesn’t get information overload. Here’s the code that I'm starting with – works nicely:
(defun c:dbinfo (/ obj v vval sal salnth count)
(setq obj (vlax-ename->vla-object (car (entsel "
Select Dynamic Block: "))))
(setq v (vla-getdynamicblockproperties obj))
(setq vval (vlax-variant-value v))
[code]....
So, how do I filter the safearray list (down two levels to property names) so I can remove origins and other unimportant properties? Here’s the two property names I am trying to filter out:
(or (= (car y) "Origin") (= (substr (car y) 1 8) "Position"))
I’m beating my head against the wall trying to figure out how to take sal and redefine it like:
(/= (or (= (car y) "Origin") (= (substr (car y) 1 8) "Position")))
Of course, that doesn't work with a safearray.

I found a function on JTBWorld named listPageSetups, which appears to be meant for listing the pagesetups that exist in an "open" dwg file (as I can get it work for the current dwg). So,
(1) Can this function be used to list page setups in another, un-opened dwg, and, if so, how?
(2) If the answer to (1) is No, is there a LISP way to get a list of page setups from another, un-opened dwg?

I have two lists with lists inside:
((A) (A) (A) (B) (B) (B) (B) (C) (C))
and
((A 1) (A 2) (A 3) (B 1) (B 2) (B 3) (B 4) (C 1) (C 2))
I just want to make a list with lists that is:
((A 1 2 3) (B 1 2 3 4) (C 1 2))
I am guessing map car and lambda should come into play but i can't figure it out.

Basically: Load the file, (workbook through active sheet: vlax-get-property)
