AutoCAD Visual LISP / AutoLISP :: Last User Entered Command Needed As String Variable
Aug 1, 2013
Main question: I need the user to be able to type a command. Then use it or cancel it. Then i need them to type another lisp command. In the second command i need to know (have the string of) the previous command they typed in. How do i get that string?
What I have tried.
I have looked at "LASTPROMPT" though not extensively, and i believe it would just return "ineedhelp" if i tried that.
I have looked at "CMDNAMES" but that gives the command you're currently in.
And I have found one page on this forum titled: Command Line History Macro, but there was no answer on that post.
I could create a global variable for that string, but then I would have to put the set code in every function I create. Nope, will not.
Backstory:
There's a person that is going to make how-to videos on how to use some of my lisp routines.
Anyhow, I need the user to be able to type in "ineedhelp" and the lisp that runs must get the last command's string go to the shared drive and pull up the video file for that command.
I have made a lisp that opened a word file before, and if i could get the string of the previous command, i'm fairly certain that I can get the videos to work.
There will be approximately 60 lisp routine video's.
I am using a variable that is being called up from a .csv file for a file name. By default this variable automatically includes a comma due to it being called from a .csv.
How to remove a character ( , ) from a variable? I'm not sure if this is along the right line or not, but i used the READ function to read the variable as a string (i think thats how it works?).
I would like to know how I can compare the value of a variable to a set string of text if the two prove to be equal perform task A if the two prove different perform task B?
I want to use it to plot different views which I will append to the command when it is called from within AutoCAD.This code will, of course, print view one.Currently my worst case is 25 views and, for that situation, I have simply repeated this code 25 times with a different function name an view number for each view. Eventually I would like to make a dialog box that would allow me to select with checkboxes (toggles) the views to print and with a button to print all.
For example, if I wanted to plot view 25, after I had loaded this lisp routine I would enter, on the command line in AutoCAD, the function name ("pp" perhaps?) followed by some variable (in this case 25, but could be any view name. ie. 01, elev, detail) and the view name would be inserted at the appropriate place.
I'm trying to make an autolisp that "flips" a third party variable. No luck, command line won't recognize after it loads. I've made similar variable flips that work ??
I'm putting together a simple lisp routine to issue bound, purged drawings.
I have code that will do the binding & purging but need handling the saving.
This is my approach :
(1) ask the user to save the drawing using this line (command "_saveas" "" "~")
(2) run a subroutine that binds xrefs etc (this works ok)
(3) run the QSAVE command
Trouble is, if the user cancels or hits escape during the SAVEAS command the subroutine & QSAVE will still run, overwriting the current drawing. How do I handle this scenario? Or should my appoach be different?
i failed to find one which would change string of a text to other for all types of objects. I mean it was usually either only multitext, or only text, dimensions or attributes.creating one which would change in abt 200 drawings:
-001
-002
-003
to:
-00001
-00002
-00003
in attributes, text, multittext, leaders, multileaders, dimensions..... at the same moment?
It is meant to be used in ScriptPro (by loading lisp in script).
If not possible, then can also open each file and run the lisp in each of them - still would save lot of time.
I am wanting to get a separate block to load if a third number is entered when prompted. If enter is hit or only 2 of the numbers are entered, load the other block. I couldn't even get it to do right by even equaling a specific number.
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 is "acl", I would like to convert it to a string "acl", everything that I have read uses alot of code. Does this really take that much code to do?
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.
I am trying to make this: L:Engineering-208037SURVEYDRAWINGS turn into this: L:Engineering-208037DRAWINGS
I am using the dwgprefix and it returns the first string and i want to make it in the second string as a new variable or replace the old variable so i can use it in a save as routine i am working on.
The problem is sometimes them project number (0208037) will be longer or shorter so i can't use the substr command
I've been working on a lisp to set up basic settings such as text styles, dim styles, discipline specific layers and things of that nature.
I have a prompt to ask for a discipline designator as a string. I want to have an If statement or a conditional to read that string and check for a "C" if it finds it I want to have it set up a dimstyle to decimal feet ect and if not do it as architectural units.
This is just a test lisp that I'd like to add to the main one listed above...
I'm working on a LISP function that adds a predetermined string to each layername in the dwg.
I came up with this:
(SETQ prefix "A-_82-_") (TBLNEXT "LAYER" T) (WHILE (SETQ la (TBLNEXT "LAYER")) (SETQ old (ASSOC 2 la) new (CONS 2 (STRCAT prefix (CDR old)))
[Code] .....
The line (princ " la is: ")(princ la) (princ " ") is thrown in to enable me to see the result of the while function, and is to be removed from the final version.
Now, everything seems to work fine, as the princ shows on the acad textstcreen.
Yet, when I check the layer palette, all layernames remain unchanged.
My guess is that I should use some other function then ENTMOD or ENTUPD to change the layertable, but I'm at a bit of a loss as to which function is required.
I have a lot of attribute blocks in my drawing which i want to move them one by one
so , here is what i want to do :
I have numbers (or texts) in my work area and this numbers also exist in my attribute blocks .. i wanna move my attribute blocks with tag name value reference to my specify area if tag name values are matching with text or numbers in this area .. every block will check my selected tag string and will be move on matching text in my work area.
I need a lisp routine that will add or subtract to modify a value in a text string. Its used for drainage fixture units on waste & vent plans. Example: We use basic dtext strings that look like this [color=red]4"(6)[/color]I would like to be able to add or subtract to the number that is [b][size=12pt]ONLY[/size][/b] in parenthesis and would like to be able to pick multiple text strings at one time so it would result in something like this: [color=green]4"(6)[/color] + 9 will become [color=blue]4"(15)[/color].
I have spent the last three days writing a lisp program that will copy a text string from one text file and paste it into another. I have tried using the write-string, getstring, prin1, princ and print functions with no success.
I am trying to change the current TARGET variable to 0,0,0. If the variable is not changed is causes problems with plotting. I have the VBA that will change the TARGET variable. VBA works no problems. I am wanting to replicate in LISP because I do not want to have to convert to .NET and do not want to make sure the user has the VBA loded on thier system. Here is what have so far.
;;;Get active viewport (setq avp (vla-get-ActiveViewport (vla-get-ActiveDocument (vlax-get-acad-object)))) ;;;Get current TARGET variable (setq CTarget(vla-get-Target avp))
Here is the problem. Is changing or putting the vaiable.I have tried
