Some people also used DIESEL to add the drawing name to. Following the Windows releases, even this use of. DIESEL was gone. So it could fade away in history. But then Autodesk released Auto.

Professionals, Read on. Professional LISP and ADS programmers probably think DIESEL is. Before you turn the page, first answer. Show me the shortest routine to extract. Heres my solution, which is nothing more than a call to DIESEL defun 3rd string. You see, DIESEL is useful even if you dont have any reason to. LT. Now if you knew this before, dont read further. Otherwise here is some DIESEL for LISPers. Professionals, dont forget RText. You dont do LISP and you dont do menu macros. OK, maybe. DIESEL really isnt for you. But do you want an Auto. CAD object. which displays as a text, but changes its contents automatically. E. g. do you want to have a. No problem, if you installed the BonusExpress tools for Auto. CAD. Release 1. 4 or beyond, look at the RText command. This creates an. RText object which acts like I just reported. And what do you do. You enter a DIESEL expression. Professionals, and use it on your own. DIESEL was written by John Walker for Autodesk, Inc. John and. Autodesk put the program and its source code in the public. You can download the complete source code from John. Walkers site at www. This allows you to embed the DIESEL interpreter into your own. Auto. CAD related or not. If you come across. DIESEL, let me know at dietmarcrlf. So far three reasons for professionals who already know. Lets now have a look at what DIESEL. A string processing language. The basic idea behind DIESEL is very simple Theres. The DIESEL interpreter takes a string, processes it, and returns. Initially the DIESEL interpreter returns every. But this would be boring. Therefore the DIESEL interpreter accepts special character. Interactive DIESELThere is no interactive version of DIESEL, i. DIESEL interpreter and print the result. But its fairly easy to build one. If you use full scale Auto. CAD, type the following lines. DIESEL s. while setq s getstring n. DIESEL T. princ menucmd strcat m s. This will implement a new command with a name of DIESEL what. It will prompt you for a string, pass this to the DIESEL. If you use Auto. CAD LT and prefer menus, add the following. DIESELCCSETENV DIESEL SETENV DIESEL MEVAL,GETENV,DIESEL The next time you start LT, the menu will recompile, and you. DIESEL command in the appropiate pull down. Click on. DIESEL. The command will prompt you for a string. DIESEL interpreter, and report the result. If you use Auto. CAD LT 9. DIESEL toolbar button. To do so, right click on any tool. New and enter DIESEL as the toolbar name. The. DIESEL toolbar opens but has no tools in it. Select. Customize, and drag a blank button from the Custom. Under Name and Help enter. DIESEL Test, as Macro enter CCSETENV DIESEL SETENV DIESEL MEVAL,GETENV,DIESELClose all toolbar dialogs. LT will recompile the menu and now. DIESEL Test command button. Again it will prompt you. DIESEL interpreter, and report the. In newer versions of Auto. CAD LT you use the same macro. Use. Tools Customize Toolbars. Use the Toolbars tab to. DIESEL toolbar, use the Commands tab to drag a. Properties tab to enter name, help string and macro. DIESEL basics. Lets start experimenting with our custom made DIESEL command. DIESEL Hello,worldHello,world DIESEL just passed the basic test for any programming. It prints the words Hello,world. But. thats not a proof, you say Maybe it did not interpret the input. OK, test 2 DIESEL Hello,world. Hello,world You see It really does something. It suppresses the. Since everything in DIESEL is. As with every other programming. The DIESEL interpreter accepts this as an input. So, how do you put a quote into a stringSimply, use two quotes. DIESEL this is just a string DIESEL Hello,world. Hello,worldDIESEL functions. As said before, passing strings through the DIESEL interpreter. Thus Autodesk added a number of. DIESEL. We may calculate the length of the. Hello,world string DIESEL strlen,Hello,world. Function calls in DIESEL are prefixed by a dollar sign and. A comma acts as the delimiter between. Arguments run until the next. You dont have to add quotes to the. If. you dont add the quotes here, the comma between. Hello and world ends the strlen argument. Using quotes in DIESEL functions is much more difficult than it. We therefore change to a simpler test string. More on quotes. DIESEL strlen,a. DIESELteststring. Any character that is not part of a function call and not a. Thus you can easily concatenate. DIESEL SNAP strlen,a. DIESELteststring. SNAP 1. 7. 0. DIESEL calculations. Always remember that DIESEL only takes strings and returns. You can calculate with strings, however, as long as they. DIESEL ,1,1. Math functions in DIESEL are, , and. The DIESEL. functions fix, rtos, angtos and edtime. Nesting DIESEL calls. Like with any other programming language you can. DIESEL ,strlen,a. DIESELteststring,strlen,anotherstring. As soon as you start writing DIESEL expressions which nest. Both Auto. CAD and Auto. CAD LT. can report the evaluation sequence and results. Simply set the. system variable MACROTRACE to 1. Heres a printout of this last. DIESEL ,strlen,a. DIESELteststring,strlen,anotherstring. Eval, strlen,a. DIESELteststring, strlen,anotherstring. Eval strlen,a. DIESELteststring. Eval strlen,anotherstring. If you create DIESEL programs, always turn the macro trace on. This will easily point you to eventual errors. DIESEL variables. DIESEL would not be a real programming language if it would. DIESEL variables can only contain strings as you would. DIESEL does not know any internal variables, but it uses. Auto. CADs variables. To retrieve the value of an Auto. CAD. variable, you use the getvar function DIESEL getvar,viewctr. Point type variables become a comma delimited string. The index. function is handy for finding the x or y coordinate of a point. DIESEL rtos,index,1,getvar,viewctr,2,3. Eval RTOS, index,1,getvar,viewctr, 2, 3. Eval INDEX, 1, getvar,viewctr. Eval GETVAR, viewctr. To save a variable value, you simply call the setvar. Auto. LISP function. Auto. CAD Release 1. USERSstring type variables for interfacing with DIESEL. Auto. CAD. LT missed these variables, but you can use the setenv. DIESEL function as a replacement. See our initial LT macro for an example. A typical problem when using Variables in DIESEL is when. Critical to this is The Macro Evaluation Sequence. Force DIESEL evaluation. The LT macro also shows how to use the eval DIESEL. The entered string is saved to the DIESEL environment. ACLT. INI file resp. Windows. registry.
