cadlabs.com - A small grab bag of tips, tools and references for AutoCAD programmers.

I've lost count; I think this is the sixth or seventh attempt to make a website using TiddlyWiki. Don't get me wrong -- there's nothing wrong with TiddlyWiki, I just tried umpteen different variants -- with and without an assortment of plugins as well as customizing the style sheet code like crazy. In the end I decided to just use the core TiddlyWiki code and go vanilla as much as possible. TiddlyWiki does a mighty fine job "out of the can" and I want to minimize "upgrade" woes down the road.\n----\nMy only real complaint so far is the rendering of mono space text (used for code snippettes) under Internet Explorer (see [[details|http://www.tiddlywiki.com/#InternetExplorer]]). It just wrecks it -- all "superfluous" spaces are stripped, competely slaying any attempts to format the code so it's readable by humans. Of course, it looks fine under FireFox <snicker>. Still, I hope this malady is fixed soon so it can display code snips consistantly accross browsers.\n----\nOther than that, woo hoo, this TiddlyWiki thing is very cool. The non linear [[Wiki]] linking thing is perfect for a code library. I can't believe I found such a great little gem. It was the result of buying David Allen's "[[Getting Things Done|http://www.davidco.com/store/catalog/Getting-Things-Done-Paperback-p-16175.php]]" book and performing some subsequent searches on the topic. One related website is [[43folders.com|http://www.43folders.com]], and it has it's own [[Wiki]]. I got to thinking that a personal [[Wiki]] would be great for a code library and abracadabra -- subsequent searches lead me to numeropus personal [[Wiki]] engines. In the end I liked TiddlyWiki the best.\n----\n<<tiddler CoolSmiley>>

Added QuoteOfTheDay and a couple other great add-ins from TiddlyTools. What a great community of developers TiddlyWiki has; w00t!\n----\nDid some experimentation trying to circumvent the mono spaced text problem ([[incorrectly rendered in Internet Explorer|http://www.tiddlywiki.com/#InternetExplorer]]). ~IFrames work, though it's a lot of effort for each [[Tiddler]] that hosts code snips. Saddy, TiddlyWiki doesn't recognize html object tags. //Still working on it ...//

Changed the site menuing system (at the upper left). Looks very clean to me now.\n----\nNow if I could just get that [[mono spaced text|http://www.tiddlywiki.com/#InternetExplorer]] to work; grrrr!

Learning a bit about css -- too cool -- great way to maintain and tweak the appearance of a web site.

Well -- tried my first stab at javascript tonight by massaging the listAll function written by Joseph Reisinger (found [[here|http://tiddlywikitips.com/#%5B%5BTip%20%2304%3A%20Tag%20Listing%20*%5D%5D]]) to produce listAllReverse (for listing blogs in reversed sort; last topmost). See [[Site Blogs]] to see it in actual use.

Added some more posts tonight, namely --\n\nAddXDictToEntity\nDistanceOf\nHiRes //and// LoRes\nIsFolderWriteable\nLayerProperties\nLoadSupport\nSetVersusSetQ

Added a couple more articles tonight --\n\n[[Children]]\n[[Evaluate]]\nFindFilesInTree\nGetDimAssocFlag\nGetDwgVersion\nGetFolders\nGetGroupNames\nIs3DPoint\nIsDigit\nIsPoint\nIsZero\nPicksetToEnames\nPurgeUnusedGroups\nSetSupportPath\nSSRedraw\n[[Replace]]\nTextpadHighlightDefuns\nUCSClassic\nGetVlaAtoms\nGetVlaMethods\nGetVlaProperties

[[Swamp post.|http://www.theswamp.org/index.php?topic=2688.msg34326#msg34326]]\n\nAn abbreviated discussion about apply, mapcar and lambda --\n\n----\n\n''Apply'' is functionally similar to, and streamlines this --\n\n{{{\n(eval (cons item list))\n\ne.g. --\n\n(eval (cons '+ '(1 2 3)))\n\n=> 6\n}}}\n\nUsing ''Apply'' --\n\n{{{\n(apply '+ '(1 2 3))\n\n=> 6\n}}}\n\nApply a function to a list of items --\n\n''Mapcar'' is a function which lets you apply a function to every item in a list, and return the result as a list. e.g. --\n\n{{{\n(mapcar 'strcase '("a" "b" "c"))\n\n=> ("A" "B" "C")\n}}}\n \n''Lambda'' allows you to define a function (an anonymous one) on the fly, right where you need it, and after it's used, *poof*, it's gone. e.g. --\n\nInstead of :\n\n{{{\n(defun foo (num) (rtos num 2 3))\n\n(setq lst (list pi (sqrt pi) (expt pi (/ 1 3.0))))\n\n(mapcar 'foo lst)\n\n=> ("3.142" "1.772" "1.465")\n}}}\n\nUse ''lambda'' --\n\n{{{\n(mapcar \n '(lambda (num) (rtos num 2 3))\n lst\n)\n\n=> ("3.142" "1.772" "1.465")\n}}}\n\n''//:)//''

[[Swamp discussion.|http://www.theswamp.org/index.php?topic=9467.msg122213#msg122213]]\n\n''APPLY''\n\nThe apply function is frequently used in conjunction with mapcar. Yet, because of that association the assumption is that it somehow //"doesn't stand on its own"//. While it can work very well in concert with mapcar there are many uses for the apply function that are fully independent of mapcar. The following attempts to help the reader understand apply a little more clearly so it can be more readily exploited -- //especially if you do wish to use it in tandem with mapcar// (smiley goes here).\n \nThe ~AutoLISP on line help sports a succint definition of apply, stating //"Passes a list of arguments to a specified function"//. While this description is perfectly adequate, the brevity may leave a noob scratching his or her respective head.\n\nI find examples the most illuminating so here we go ...\n\nAssume we have a number of integers, 8 2 5 1 14 4 5 3 and we want to find the largest one. Normally you would use the max function, which takes numbers as its arguments --\n\n{{{\n(max 8 2 5 1 14 4 5 3) => 14\n}}}\n\nWhich returns 14 (shown above as => 14, the convention used for the balance of this discussion).\n\nThis is fine, but what if the numbers are stored in a list?\n\n{{{\n(setq numbers '(8 2 5 1 14 4 5 3))\n}}}\n\nHow would you use the max function with a list, since it takes numbers, not lists as it arguments?\n\nYou cannot use --\n\n{{{\n(max numbers) => error => bad argument type.\n}}}\n\nBut you can use --\n\n{{{\n(apply 'max numbers) => 14\n}}}\n\nIf you are familiar with the eval and cons functions it would be equivalent to --\n\n{{{\n(eval (cons 'max numbers)) => 14\n}}}\n\nOr (using eval and append) --\n\n{{{\n(eval (append '(max) numbers)) => 14\n}}}\n\nOr (using eval, append and list) --\n\n{{{\n(eval (append (list 'max) numbers)) => 14\n}}}\n\nObviously apply is more elegant and succinct.\n\nLet's explore some more examples (remember the variable 'numbers' is set to '(8 2 5 1 14 4 5 3)) --\n\n{{{\n(apply 'min numbers) => 1\n(apply '+ numbers) => 42\n(apply '* numbers) => 67200\n}}}\n\nCan you visualize what's happening above?\n\nLet's abandon the numbers and concatenate a simple list of strings ...\n\n{{{\n(apply 'strcat '("A" "B" "C")) => "ABC"\n}}}\n\nEasy stuff.\n\nHope this little discussion and these simple examples help you understand the apply function, it's a convenient little creature I dare say.\n\n----\n\nFor an abbreviated discussion of ''mapcar'' / ''lambda'' please see MapcarLambdaOhMy.

I wrote [[AxProps|http://www.theswamp.org/lilly_pond/mp/lisp/axprops.fas?nossi=1]] (use your logon name / password to download), a little utility that provides a simple gui interface to display all the properties and methods exposed to ~AutoLISP (via vla-*, vlax-get/put/invoke etc.) for a specified entity or object -- \n\n[img[http://cadlabs.com/images/axprops01.png]]\n\nDouble clicking an entry in the dialog will invoke the help system and display the appropriate help (if a topic for that item exists) --\n\n[img[http://cadlabs.com/images/axprops02.png]]\n\n[img[http://cadlabs.com/images/coordshelp.png]]\n\nFinally, when there is a difference in the result returned by vlax-get and vlax-get-property (the former generally returning data types native to ~AutoLISP, the latter data types native to ~ActiveX), it shows both results separate by a " | " (pipe) symbol --\n\n[img[http://cadlabs.com/images/axprops03.png]]\n\nDownload -- \n\n[[AxProps.fas|http://www.theswamp.org/lilly_pond/mp/lisp/axprops.fas?nossi=1]] (use your logon name / password).\n\nCommand / Functions --\n*''c:~AxProps'' -- prompts you to to select an entity.\n*''c:~NAxProps'' -- prompts you to to select a nested entity.\n*''~AxProps'', syntax: ''(~AxProps x)'', where x is any valid object, ename or handle.\nFeel crazy? Try this ''(axprops "1")'', lol.\n\nI plan to add the ability to dump the whole mess to notepad so you can use the info in other ways, print off etc. Other ideas welcome, will try to incorporate ideas keeping with it's simple philosophy and lightweight footprint when I've the time.\n\nFinal note: I wrote this quick under Windows XP Pro and vanilla ~AutoCAD 2006.

[[Swamp post.|http://www.theswamp.org/index.php?topic=6741.msg83220#msg83220]]\n\nI've frequently heard how difficult or laborious dcl programming is and I just don't see it. While a dcl based dialog can't challenge one defined by a more modern application like Delphi or Visual BASIC, they're a snap to make (and since they're plain text, can be written on the fly, though that's another discussion), particularly if you build sub assemblies to use in your dialog. Once you define sub assemblies the only thing, generally speaking, that varies from instance to instance is the key (and sometimes the label).\n\nFor example, in the dcl Alan authored (in the Swamp link above) it could be broken down as follows (this would all be in one file, but breaking it up like this for discussion makes it easier to digest) --\n\n''General dcl settings'' -- \n\n{{{\n//\n// general dcl settings \n//\n\ndcl_settings : default_dcl_settings\n\n{ audit_level = 3; }\n}}}\n\n''Sub assembly definitions'' --\n\n{{{\n//\n// sub assembly definitions\n//\n\nattribute_prompt : text {\n value = "Attribute Prompt" ;\n width = 30;\n fixed_width = true;\n}\n\nattribute_value : edit_box {\n edit_width = 34;\n edit_limit = 200;\n fixed_width = true;\n}\n\nattribute_state : image_button {\n height = 1;\n width = 2;\n fixed_width = true;\n fixed_height = true;\n aspect_ratio = 1;\n color = -15;\n}\n\nmybutton : button {\n width = 12;\n fixed_width = true;\n}\n}}}\n\n''Dialog definition'' --\n\n{{{\n//\n// dialog definition\n//\n\nMyAttEdit : dialog {\n \n label = " MyAttEdit by CAB v1.0";\n \n : text {\n value = "Block Name: My Block";\n key = "txtblock";\n width = 50;\n } \n\n : text {\n value = "Page # ";\n key = "page";\n width = 10;\n alignment = right;\n } \n \n spacer_1;\n \n // use the sub assemblies we defined\n \n : row {\n : attribute_prompt { key = "txt1"; } \n : attribute_value { key = "eb1"; } \n : attribute_state { key = "im1"; } \n }\n \n : row {\n : attribute_prompt { key = "txt2"; } \n : attribute_value { key = "eb2"; } \n : attribute_state { key = "im2"; } \n }\n \n : row {\n : attribute_prompt { key = "txt3"; } \n : attribute_value { key = "eb3"; } \n : attribute_state { key = "im3"; } \n }\n \n : row {\n : attribute_prompt { key = "txt4"; } \n : attribute_value { key = "eb4"; } \n : attribute_state { key = "im4"; } \n }\n \n : row {\n : attribute_prompt { key = "txt5"; } \n : attribute_value { key = "eb5"; } \n : attribute_state { key = "im5"; } \n }\n \n : row {\n : attribute_prompt { key = "txt6"; } \n : attribute_value { key = "eb6"; } \n : attribute_state { key = "im6"; } \n }\n \n : row {\n : attribute_prompt { key = "txt7"; } \n : attribute_value { key = "eb7"; } \n : attribute_state { key = "im7"; } \n }\n \n : row {\n : attribute_prompt { key = "txt8"; } \n : attribute_value { key = "eb8"; } \n : attribute_state { key = "im8"; } \n }\n \n spacer_1;\n\n : row { \n : mybutton { key = "ok"; label = "&OK"; }\n : mybutton { key = "cancel"; label = "&Cancel"; is_cancel = true; }\n : mybutton { key = "prev"; label = "&Previous"; }\n : mybutton { key = "next"; label = "&Next"; }\n : mybutton { key = "help"; label = "&Help"; }\n }\n\n}\n}}}\n\nThis greatly speeds up dcl development, moreover, it makes maintenance a snap. Did ya note how I right aligned the key values for all the instanced sub assemblies? Makes it easy to assign and ensure the keys are correct (typically numerically incremented). \n\nBut more on maintenance ...\n\nFor example, if the {{{attribute_prompt}}} sub assembly width is found to be too wide, the {{{width = 30;}}} statement could be changed to {{{width = 25;}}} and all 8 instances will reflect same. Really takes the chore out of maintenance and makes it a lot easier to achieve consistancy throughout a dialog. \n\nAnother example: Say we decide to change the {{{attribute_state}}} sub assembly to a {{{text tile}}} from an {{{image_button}}}. No Problem --\n\n{{{\n/*attribute_state : image_button {\n height = 1;\n width = 2;\n fixed_width = true;\n fixed_height = true;\n aspect_ratio = 1;\n color = -15;\n}*/\n\nattribute_state : text {\n fixed_width = true;\n width = 1;\n is_bold = true;\n}\n}}}\n\nNow all 8 instances of {{{attribute_state}}} are {{{text tiles}}} instead of {{{image buttons}}} (ps: I think if you made the image buttons just image tiles there may not be a border around them Alan). \n\nOf course the code would have to reflect same:\n\n{{{\n(defun asterisk ( tile / x y )\n\n (set_tile tile "*")\n \n ;| <comment out former code>\n \n (setq \n X (dimx_tile tile)\n Y (dimy_tile tile)\n )\n (start_image tile)\n (fill_image 0 0 x y -15)\n (mapcar 'vector_image; Color 1\n (list 5 1 1 0)\n (list 0 9 1 5)\n (list 5 9 9 10)\n (list 10 1 9 5)\n (list 1 1 1 1)\n )\n (end_image)\n\n </comment out former code> |;\n)\n}}}\n\nAnd:\n\n{{{\n(defun ast_clear ( tile / x y )\n\n (set_tile tile "")\n \n ;| <comment out former code>\n\n (setq \n X (dimx_tile tile)\n Y (dimy_tile tile)\n )\n (start_image tile)\n (fill_image 0 0 x y -15)\n (end_image)\n\n </comment out former code> |;\n)\n}}}\n\nFinal tip: Read up on the {{{@include}}} statement (in the context of dcl source files and subassembly discussion above).\n\n:-D

What can I say, a great browser. Not perfect but more perfect than Internet Explorer and Opera in my opinion. \n\nFireFox ([[download here|http://www.mozilla.com/firefox]]) correctly renders mono spaced text (used in all code snippettes herein) unlike Internet Explorer ([[details here|http://www.tiddlywiki.com/#InternetExplorer]]) which makes a complete mess of it. \n\n[[Flock]], FireFox's leaner cousin, also renders mono spaced text correctly, though it's still a pre-release (technology review) product.\n\n''Links --''\n<<<\n[[www.mozilla.com/firefox|http://www.mozilla.com/firefox]]\n\n[[http://www.flock.com|http://www.flock.com]]

Flock is a light weight internet browser built using the open source mozilla code base.

Example, if the reference file\n ;; I'm interested in (using full path as a key) exists in my\n ;; master file info list use the data associated with that\n ;; key, otherwise poll the system for that info and add said\n ;; info into my master list. If the system did not return\n ;; info for said file (e.g. not found) make sure you add that\n ;; key to the master list with either a null association or\n ;; some indiction that the info is N/A, like '("N/A" "N/A")\n ;; lest the application continue poll the system for a file\n ;; known to be unavailable.\n ;;\n ;; For example, a master file info list, say global variable\n ;; *fileData* might look something like this:\n ;;\n ;;

[[Swamp discussion.|http://www.theswamp.org/index.php?topic=4041.0]]\n\nGiven the discussion [[here|http://theswamp.org/phpBB2/viewtopic.php?t=4025]] (hmmm, thread has gone 404), I thought "How might I write a simplistic 'globals manager' for values to be retained between function calls within an ~AutoCAD session", i.e. not between ~AutoCAD sessions? A little utility could be written to manage globals by keeping them all in a simple structured list - that is - global. The latter (session to session variable retension) would probably be best in a dictionary or some other permanent data storage mechanism.\n\nThe question looms -- "Couldn't I just use a global like *textheight* to store the global value for my application?" The answer is "Absolutely", but what fun is that for me?\n\nAnyway ...\n\n3 basic functions, naming should spell out the functionality --\n*(''~PutGlobal'' funcName symName symValue)\n*(''~GetGlobal'' funcName symName defaultValue)\n*(''~ClearAllGlobals'')\nLet's say I've written a utility to do some kind of annotating, and I want to have a global for the text height (simplistic example) --\n\n{{{\n(defun c:MyNotes ( / textHeight )\n\n ;; get the text height for this\n ;; app from the global manager\n\n (setq textHeight\n (GetGlobal\n 'c:mynotes ;; funcName\n 'textheight ;; symName\n (/ 3 32.0) ;; defaultValue\n )\n )\n \n ;; do great stuff, which may\n ;; include prompting the user\n ;; for atext height etc (not the\n ;; focus for me here)\n \n (DoGreatStuff)\n \n ;; ok, save the text height we\n ;; used to our global heap before\n ;; we exit this application\n \n (PutGlobal\n 'c:mynotes ;; funcName\n 'textheight ;; symName\n textHeight ;; symValue\n ) \n \n (princ)\n \n)\n}}}\n\n{{{\n(defun GetGlobal ( funcName symName defaultValue / result )\n\n ;;=================================================================\n ;;\n ;; GetGlobal | © 2005 Michael Puckett | All Rights Reserved\n ;;\n ;;=================================================================\n ;;\n ;; Purpose:\n ;;\n ;; Provide a simple mechanism to retrieve the value for the\n ;; symName associated with the funcName in global variable\n ;; *globals*.

From [[www.tiddlywiki.com/#HowToUpgrade|http://www.tiddlywiki.com/#HowToUpgrade]].\n<<<\nThe core TiddlyWiki code is regularly updated with bug fixes and new features. If you're using an earlier revision of TiddlyWiki, here's the simple way to upgrade to the latest version:\n* Open your TiddlyWiki file in FireFox (say it's called "mystuff.html")\n* SaveChanges (with SaveBackups switched on) to make sure that you've got a backup of it\n* Without closing that page, right-click on [[this link|http://www.tiddlywiki.com/empty.html]], select 'Save target' or 'Save link' and save it as "mystuff.html", replacing your existing file\n* Now go back to the previously opened copy of "mystuff.html" in your browser and SaveChanges again. It will inherit the newly saved code\n* Refresh the page in the browser to verify that the upgrade has worked\nThe most likely cause of the upgrade process not working properly is that one of the [[Plugins]] you're using is not compatible with a change in the new release. If so, you can use the [[ImportTiddlersPlugin|http://www.tiddlytools.com/#ImportTiddlersPlugin]] from TiddlyTools to selectively import your content and [[Plugins]] into a new empty TiddlyWiki.

Please send all inquiries to --\n\n@@[cadlabs]@@ @@[at]@@ @@[gmail]@@ @@[dot]@@ @@[com]@@\n\n^^(Please forgive the obfuscated email address, sadly necessary to thwart spam bots and their ilk).^^

[[Plugins]] are just tiddlers containing JavaScript code that is tagged with <<tag systemConfig>> (see [[TiddlyWiki/Dev]] for information on writing your own plugins). TiddlyWiki executes any [[Plugins]] as it loads; they can add [[Macros]] or otherwise extend and enhance the base code.\n\nThe recommended way to install a plugin into your own copy of TiddlyWiki is to take it direct from the plugin author's site (see [[Plugins]] for a list of some of the main ones):\n# If you haven't already done so, follow the instructions in DownloadSoftware to make your own local copy of TiddlyWiki\n# Let's assume that you wish to download EricShulman's ImportTiddlersPlugin\n# Open a new browser window and navigate to http://www.tiddlytools.com/#ImportTiddlersPlugin\n# Double click the tiddler, or click the {{{source}}} button (on other sites it will sometimes be a {{{view}}} or {{{edit}}} button)\n# The entire text of the tiddler should be selected; if not select it manually with Control-A or Command-A\n# Copy the entire text of the tiddler to the clipboard\n# Open your TiddlyWiki file in a new browser window\n# Click {{{new tiddler}}} to create a new blank tiddler\n## Paste the contents of the clipboard into it's body\n## Set the title to {{{ImportTiddlersPlugin}}}\n## Add the tag {{{systemConfig}}}\n# Click {{{done}}} on the tiddler\n# SaveChanges\n# Reload your TiddlyWiki in the browser\nThe plugin should now be available for use.

[[Swamp discussion.|http://www.theswamp.org/index.php?topic=2953.0]]\n\nOn another forum (not a CAD forum) I was asked to explain (for the 42nd time) the mapcar lambda thing, and while I feel the topic has been covered adequately by many different authors it seems some folks still find it confusing. \n\nSo ... I took a different approach: Rather than an encyclopedic spray of geek speak I just used tiny examples, and similarly, a simple, casual conversation. It is not exhaustive, it is not thorough, on the other hand its light, easy to digest; no acid reflux ...\n\n----\n\n''MAPCAR''\n\nFirst: When to use mapcar?\n\nGenerally speaking, use mapcar when you have a list of values and you want the result of some modification to that list to be returned as a list.\n\nOk, umm ... let's start with a list of strings:\n\n{{{\n(setq lst\n '( "joshua"\n "mary"\n "jim"\n )\n)\n\n=> ("joshua" "mary" "jim")\n}}}\n\nLet's say we want all these string to be uppercase but we still want all the names in a list. How could we do this without iterating the list (say with foreach) and constructing a new list?\n\nEasy, use mapcar with the strcase function:\n\n{{{\n(mapcar\n 'strcase\n lst\n)\n\n=> ("JOSHUA" "MARY" "JIM")\n}}}\n\nOk ... but let's say we want to change them to proper case (first letter uppercase, balance lowercase). There is no function to do that.\n\nOne way is to write our own function:\n\n{{{\n(defun Proper ( str )\n (strcat\n (strcase (substr str 1 1))\n (strcase (substr str 2) t)\n )\n)\n}}}\n\nThen use it just like we did with the strcase function:\n\n{{{\n(mapcar\n 'Proper\n lst\n)\n\n=> ("Joshua" "Mary" "Jim")\n}}}\n\nBut what if we don't want the overhead of a formal function declaration (that will hang round after we're done with it)?\n\n''LAMBDA''\n\nEasy, use lambda to create an anonymous function on the fly -- right where we need it (which will be discarded immediately after it is used):\n\n{{{\n(mapcar\n '(lambda ( str )\n (strcat\n (strcase (substr str 1 1))\n (strcase (substr str 2) t)\n )\n )\n lst\n)\n\n=> ("Joshua" "Mary" "Jim")\n}}}\n\nDid ya notice the similarity between the defun declaration of Proper and the lambda code that achieves the same?\n\nHope this is illuminating; cheers.\n\n:)\n\n----\n\nFor an abbreviated discussion of the ''apply'' function please see ApplyOhMy.

From http://www.tiddlywiki.com/#MicroContent --\n<<<\nMicroContent being a fashionable word for self-contained fragments of content that are typically smaller than entire pages. Often MicroContent is presented via some kind of aggregation that reduces the perceptual shock and resource cost of context switching (eg Blogs aggregating several entries onto a page or Flickr presenting photos in an album). This TiddlyWiki aggregates MicroContent items that I call 'tiddlers' into pages that are loaded in one gulp and progressively displayed as the user clicks hypertext links to read them.

The order of this tiddler display depends upon when and where you have clicked. Some people like this non-linear method of reading the document, while others have reported that when many tiddlers have been opened, it can get somewhat confusing.\n\n!!!!!Usage\n<<<\nSinglePageMode allows you to configure TiddlyWiki to navigate more like a traditional multipage web site with only one item displayed at a time. You can select a checkbox in the AdvancedOptions tiddler to enable this behavior or revert to the standard TiddlyWiki multiple tiddler display behavior.\n\nWhen SinglePageMode is enabled, the title of the current tiddler is automatically displayed in the browser window's titlebar and the browser's location URL is updated with a 'permalink' for the current tiddler so that it is easier to create a browser 'bookmark' for the current tiddler.\n\n//Note: This feature currently effects ALL tiddler display behavior, including features that normally result in multiple tiddlers being displayed, such as the results of searches or the initial DefaultTiddlers shown when the document is loaded. //\n<<<\n!!!!!Configuration\n<<<\nWhen installed, this plugin automatically adds a checkbox in the AdvancedOptions tiddler so you can enable/disable the plugin behavior.

TiddlyWiki now defines a small number of SpecialTags that are used to indicate that tiddlers should be treated differently in some way:\n* ''excludeSearch'': excludes a tiddler from search results\n* ''excludeLists'': excludes a tiddler from the lists in the sidebar tabs\n* ''systemTiddler'': marks tiddlers whose content is used to create paraphernalia like the main menu, title and sidebar. These tiddlers are included if you use the SaveEmptyTemplate option\n* ''systemConfig'': marks tiddlers that contain JavaScript that should be executed once TiddlyWiki has loaded

''Swanson's Unwritten Rules''\n<<<\n#Learn to say, "I don't know." If used when appropriate, it will be used often.\n#It is easier to get into something than to get out of it.\n#If you are not criticized, you may not be doing much\n#Look for what is missing. Many know how to improve what's there; few can see what isn't there.\n#Presentation rule: When something appears on a slide presentation, assume the world knows about it and deal with it accordingly.\n#Work for a boss to whom you can tell it like it is. Remember, you can't pick your family, but you can pick your boss.\n#Constantly review developments to make sure that the actual benefits are what they were supposed to be. Avoid Newton's Law.\n#However menial and trivial your early assignments may appear, give them your best effort.\n#Persistence or tenacity is the disposition to persevere in spite of difficulties, discouragement or indifference. Don't be known as a good starter but a poor finisher!\n#In doing your project, don't wait for others; go after them and make sure it gets done.\n#Confirm the instructions you give others, and their commitments, in writing. Don't assume it will get done.\n#Don't be timid: Speak up, express yourself and promote your ideas.\n#Practice shows that those who speak the most knowingly and confidently often end up with the assignment to get the job done.\n#Strive for brevity and clarity in oral and written reports.\n#Be extremely careful in the accuracy of your statements.\n#Don't overlook the fact that you are working for a boss. Keep him or her informed. Whatever the boss wants, within the bounds of integrity, takes top priority.\n#Promises, schedules and estimates are important instruments in a well-run business. You must make promises — don't lean on the often-used phrase: "I can't estimate it because it depends on many uncertain factors."\n#Never direct a complaint to the top; a serious offense is to "cc" a person's boss on a copy of a complaint before the person has a chance to respond to the complaint.\n#When interacting with people outside the company, remember that you are always representing the company. Be especially careful of your commitments.\n#Cultivate the habit of boiling matters down to the simplest terms: the proverbial "elevator speech" is the best way.\n#Don't get excited in engineering emergencies: Keep your feet on the ground.\n#Cultivate the habit of making quick, clean-cut decisions.\n#When making decisions, the "pros" are much easier to deal with than the "cons." Your boss wants to see both.\n#Don't ever lose your sense of humor.\n#Have fun at what you do. It will be reflected in you work. No one likes a grump except another grump!\n#Treat the name of you company as if it were your own.\n#Beg for the bad news.\n#You remember 1/3 of what you read, 1/2 of what people tell you, but 100% of what you feel.\n#You can't polish a sneaker.\n#When facing issues or problems that are becoming drawn-out, "short them to the ground."\n#When faced with decisions, try to look at them as if you were one level up in the organization. Your perspective will change quickly.\n#A person who is nice to you but rude to the waiter, or to others, is not a nice person. (This rule never fails).\n#Never be afraid to try something new. Remember, an amateur built an ark that survived a flood while a large group of professionals built the Titanic!\nPostscript: The qualities of leadership boil down to confidence, dedication, integrity and love.\n\n[[Source.|http://www.usatoday.com/money/companies/management/2006-04-14-ceos-waiter-rule_x.htm]]

Excerpt from http://wiki.org/wiki.cgi?WhatIsWiki --\n<<<\n[[Wiki]] is in Ward's original description:\n\nThe simplest online database that could possibly work.\n\n[[Wiki]] is a piece of server software that allows users to freely create and edit Web page content using any Web browser. [[Wiki]] supports hyperlinks and has a simple text syntax for creating new pages and crosslinks between internal pages on the fly.\n\n[[Wiki]] is unusual among group communication mechanisms in that it allows the organization of contributions to be edited in addition to the content itself.\n\nLike many simple concepts, "open editing" has some profound and subtle effects on [[Wiki]] usage. Allowing everyday users to create and edit any page in a Web site is exciting in that it encourages democratic use of the Web and promotes content composition by nontechnical users.

Excerpt from http://www.tiddlywiki.com/#WikiWikiWeb --\n<<<\nA [[Wiki]] is a popular way of building collaborative websites. It's based on the two ideas of allowing users to easily edit any page and the use of special WikiWord notation to automagically create links between pages. See Wikipedia for [[more details|http://en.wikipedia.org/wiki/Wiki]].\n\nTiddlyWiki is fundamentally different from a conventional [[Wiki]] because it is not based on separate, entire pages of content, but rather items of MicroContent referred to as [[Tiddlers|Tiddler]] that live together on the same page.\n\nOut of the box, TiddlyWiki is also different because it doesn't support public editing - or indeed any persistent editing when viewed over the web.

From http://www.tiddlywiki.com/#WikiWord --\n<<<\nType the text for 'New Tiddler'A WikiWord is a word composed of a bunch of other words slammed together with each of their first letters capitalised. WikiWord notation in a conventional WikiWikiWeb is used to name individual pages while TiddlyWiki uses WikiWord titles for smaller chunks of MicroContent. Referring to a page with a WikiWord automatically creates a link to it. Clicking on a link jumps to that page or, if it doesn't exist, to an editor to create it. It's also easy to have ~NonWikiWordLinks, and there's a ~WikiWordEscape for situations where you don't want a WikiWord to be interpreted as a link.

Welcome to [[cadlabs.com]], a small grab bag of tips, tools and references for ~AutoCAD (primarilly LISP) programmers.\n\n''Notes --''\n*[[cadlabs.com]] was created using FireFox and [[TiddlyWiki]] (a clever personal WikiWikiWeb engine written in HTML, CSS and ~JavaScript).\n*You must have a membership at [[theswamp.org]] and be logged in to follow many of the [[theswamp.org]] links herein.\n*This site appears best when viewed from FireFox.\n**Code snippettes (mono space text) are currently not rendered correctly under Internet Explorer (surprise). It strips out extra spaces typically used to indent and format code. See [[link|http://www.tiddlywiki.com/#InternetExplorer]]. \n**Some menus and popups look kinda goofy under Internet Explorer. \n**Shouldn't I try to ensure this site renders well in any browser? Probably, but I'm not concentrating on that right now -- I'm loathe to accomodate Internet Explorer quite frankly.\n**FireFox renders mono spaced text and menus just fine. //Surprised?//\n*Unless noted otherwise all content © 2006 Michael Puckett.

@@In my opinion the best ~AutoCAD discussion forum on the net@@. \n\n[img[http://cadlabs.com/images/theswampscreen.png]]\n\nIt's free, clean (no advertisements) and some of the world's best programmers hang their hats there. It is a friendly and cordial forum frequented by a spectrum of talented and nice folks. Even if you tend to be a forum lurker there is a wealth of ~AutoCAD (and verticals) and programming (~VisualLISP, ~VisualBASIC, Python, C# etc) information therein. \n\nWhat are you waiting for -- go get yourself a free account!\n\n[[http://www.theswamp.org|http://www.theswamp.org]]
