AfraLISP helps you learn how to use AutoLISP the AutoCAD API. Learn how to become more productive with AutoCAD by writing your own AutoLISP routines. I Will Im an italian developer and I developed an application in autocad vba that allows you to make plans for a loft in carpentry with the automatic generation. Lisp Tutorial Autocad Civil 3dA script is a macro, a list of commands that you can run all at once, and as many times as necessary, allowing you to automate tasks that would take a long time if. Lisp Tutorial Autocad 2015' title='Lisp Tutorial Autocad 2015' />Memory was low then in the late 8. Since then the language. From time to time some library functions were. DCL support a cross platform Dialog Control Language. More language features or library functions never made it besides some. Vital Lisp now Visual Lisp. The language has several milestones since 1. R1. 0. acomp bytecode compiler for european developers, also xlisp based R1. R1. 2. Vital Lisp, external compiler and development system R1. R1. 4. Reactors and Automation support vill 3. Visual Lisp, based on vill 3. Auto. Lisp in R1. Auto. CAD 2. 00. 0. Some trickies and goodies. General speaking sorting in plain Auto. LISP is a pain in the ass, because. But. use adsstrlsort or any other ADS sort which you can get. Visual Lisp is usually the best. Without VLISP use the stdlib implementation. In Lisp the mostly used sort method is merge sort also used in str sort in Auto. Desks TABLES. LSP sample because thats a. Normally in C eg. Common Lisp sorting code is here. The best and cleanest implementation so far is from Serge Pashkov, a stable. Auto. LISP, provided with the stdlib, in. STDLIST. LSPReferences. Sedgewick Algorithms. Knuth part 3, Winston Horn Lisp. The Common Lisp sort function looks like this sort sequence less than predicate simplifiedIn Auto. LISP try to implement it like this sort list lambda expr. In the examples below only William Kiernans nssort works like this. A more complicated usage example with mixed alphabetical and numerical parts. ADSCL sort benches by Vladimir Nesterowsky. All other sort implementations below should be examined for tutorial. Daniele Piazza. lispsort by T. J. Di. Tullio. bubble and shell sort examples for one and more lists. Auto. DESK has a cute example on its server. Now who was the first ACAD Plus. Performance comparison of two classic sort algorithms. Performs a sort on long and short. Includes useful timing routines. My own collection of simple lisp sort functions. TRBLSORT ADS qsort by William Kiernan. Sort code from the ATJ V1. N4 magazine. sort data method method less than predicate. You want to know the fastest sort method First of all it depends on your data. Strings should always be sorted. Numbers or. points can be converted to strings http ourworld. ADShttp xarch. With Vital Lisp use the builtin vlx sortmerge sort is usually fastest but uses the most resources see the FAQ. Some tricky sort functions use the internal hash table for fast symbol. I compiled the ultimate textbook Common Lisp The Language 2nd Edition to. Windows HTMLHelp 1. This is more verbose but less exact than the Hyperspec, for which I have to wait for permission. I also compiled the complete reference Common Lisp Hyperspec to. Windows HTMLHelp 3. Harlequin, before publication, because I fixed some formatting. BTW Microsofts free HTML Workshop 1. CHM from HTML or Winhelp. Youll need IE4 to read it or this hhupd 1. I maintain the Corman Lisp. Auto. CAD ARX stub and. Auto. CAD module. The ARX needs version Corman Lisp 1. Now we have COM access to ACAD. ACAD. EXE as with ARX. It needs ccl version 1. We. are trying to produce the necessary CLOS code automatically by parsing. ACAD. TLB and acad. This enables easier. Rational. Rose support for cross platform development is also doable, but not. Ask Ralph Gimenez for this biest. I also compiled the. Corman Lisp docs v. Winhelp and HTMLHelp recently. CHM and CLt. L2 support. Ralph Gimenez SAGE CLOS for Visual Lisp is ready. A demo and some samples will be. It implements most of CLOS functionality in pure Auto. LISP, the only drawback is. ANSI compatible because Auto. LISP supports. no macros, no optional arguments and no reader macros like, backquote and comma. Anyway, its the best, leaving better Lisps aside. View the thread on usenet. I implemented some CL functions too. Some are part of the. Auto. LISP Standard Library and some are in autocadcoderurban. I have almost ANSI compatible defstruct, setf, vectors, arrays and Im writing on a better backquotecomma than ralph gimenez already has in his sage clos, requiring a better eval read load to support backquote. Autodesk will probably enhance the Auto. LISP language after acquiring the. Vital Lisp sources and according this. Evaluate and recommend various technical possibilities for expanding. Auto. LISP coverage in future Auto. CAD releases including closer correspondence. Common Lisp. But this was some years ago and nothing happened. Data Lidar Indonesia Map Asia. Only Active. X support was improved exceptions, safearrays. Fundamental differences between dynamical binding vs. Jeff Dalton. Auto. LISP uses dynamical binding for all symbols, in. Common Lisp or true lisps you may choose it by yourself, but by. In Auto. LISP global. This may be a problem in. Auto. LISP, esp. for. SAGE CLOS does it just fine. But for dialog. callbacks the usual way to handle list data is through dynamic. The Beauty of Recursion. Old examples from the WinstonHorn standard LISP textbook and a few. Corrected some nasty bugs. New In this text theres a lot of talk about the advantages of tail recursion. Recently I found a very nice text. Winston Horn. LISP is not on line. Note VLISP uses no tail recursion, so it is still stack exhaustive. See stdlibSTDINIT2. LSP for the values of. WinstonHorn simple match. Auto. LISP. WinstonHorn extended whmatch. Auto. LISP fixed. WCMATCH workaround. CASE and LET, functions from Common Lisp. ARRAY, AREF, functions from Common Lisp. Sooner or later my implementation of defstruct, setf defsetf, get. Ports will be made from this codestdlibtestRUNTEST. LSP. lets you test automatically function return values. It checks files like this. Theres also a runtest. Then you could. check if functions correctly throw an error exception. Binary Search Trees. I ported the example from ANSI CL by. Paul Graham to Auto. LISP to have at least one fast and efficient data structure for fast searches. But updates are costly, so it can only be used for static code. Hashes and vectors are still impossible for the plain Auto. LISP programmer. Vital Lisp Professional owners may ask for my vector and hash functions but. I will have to ask Basis or adesk now first. News from the hash and vector front I recently implemented arrays and vectors with constant access and modification time. Auto. LISP, using only stdlib functions. The trick is explained in this.
