• Possible Bug: Variable Assignment Gets Swallowed By Function Invocation In Lucee 5.3.2.77

  Posted on Jul 19, 2019 at 1:45 PM

  @Chris, That's just how I've always done it :D I like putting parenthesis around stuff!... read more »

• Possible Bug: Variable Assignment Gets Swallowed By Function Invocation In Lucee 5.3.2.77

  Posted on Jul 19, 2019 at 1:44 PM

  @All, Sorry -- I'm a doofus -- when using the = in the context of a Function, this is actually method invocation named parameters . As such, this is doing what it is supposed to do. I was so focused on the syntax that I didn't even think about the Function all.... read more »

• Immediately Invoked Function Expressions (IIFE) Work In Lucee 5.3.2.77

  Posted on Jul 19, 2019 at 9:31 AM

  @Charles, The "self-executing" part is the thing that produces the nextID() function, not the invocation of nextID() itself, if that makes sense. Basically, it's just this part: (() => { ....... })(); Yeah, there are other ways to do this -- mostly, I was just exc... read more »

• I Can Finally Embed An Assignment Operation Inside Of Other Expressions In Lucee 5.3.2.77

  Posted on Jul 19, 2019 at 6:46 AM

  @All, Here is the documentation of the bug I found: https://www.bennadel.com/blog/3662-possible-bug-variable-assignment-gets-swallowed-by-function-invocation-in-lucee-5-3-2-77.htm In Lucee 5.3.2.77, you cannot use variable assignment as part of a Function call - it completely suppresses ... read more »

  Posted on Jul 19, 2019 at 6:44 AM

  @All, I attempted to file the bug here: https://luceeserver.atlassian.net/browse/LDEV-2380 I think I've tried this before and didn't do it correctly. But, I don't remember what I was doing incorrectly last time :D... read more »

  @Tony, Right?! Now, to figure how it can actually be used :P... read more »

• I Can Finally Embed An Assignment Operation Inside Of Other Expressions In Lucee 5.3.2.77

  Posted on Jul 18, 2019 at 8:26 AM

  @All, Ok, so it turns out that this approach - using assignment within a parent expression - is actually buggy in Lucee. While it happens to work inside of a return statement, it does not seem to work elsewhere. I will write this bug up in the morning and report it (assuming it... read more »

• CFThread Attributes Are Passed By Reference - Not By Deep Copy - In Lucee 5.3.2.77

  Posted on Jul 17, 2019 at 6:09 PM

  @Charles, I mean, that's a really good idea. With other things, I'm pretty sure that Lucee has a setting where you can "enable" the Adobe ColdFusion compatible behavior in the Application.cfc . Also, I was just looking at the "syntax" differences, and I do see that you... read more »

• CFThread Attributes Are Passed By Reference - Not By Deep Copy - In Lucee 5.3.2.77

  Posted on Jul 17, 2019 at 5:21 PM

  @Charles, It's a really good point. If nothing else, there's the "breaking change" aspect of it that I haven't seem really documented. At least, not that I can remember coming across. My assumption is that since things like runAsync() and all the parallel iteration features (ex... read more »

• Restoring And Resetting The Scroll Position Using The NavigationStart Event In Angular 7.0.4

  Posted on Jul 17, 2019 at 8:08 AM

  @Michael, Hmm, that's really strange. It is my understanding that the scrollPositionRestoration: 'top' and / or scrollPositionRestoration: 'enabled' is supposed to do exactly what you are thinking it should do. To be clear, you are talking about "new navigations" (ie, ... read more »

• Webpack 4 Automatically Makes process.env.NODE_ENV Available In Your JavaScript

  Posted on Jul 17, 2019 at 8:04 AM

  @Brian, That sounds like a sticky situation. I've only just begun to try using the Angular CLI -- the idea of doing any Universal Rendering feels like light-years in the future. I'm happy to have this tip in my back-pocket for when I finally get there.... read more »

• Using A Wild Card Route (**) To Traverse Arbitrarily Nested Data In Angular 7.2.4

  @Ihor, Awesome - I'm happy you found this helpful. It's definitely something I am intending to retrofit into a few places in our production app.... read more »

• The CFQuery Tag Supports Silent Asynchronous Query Execution In Lucee 5.3.2.77

  @Frédéric, Very cool -- I'm glad to be able to shed some light. I feel like a kid in a candy store, switching over to Lucee :D... read more »

• Deeply Nested CFThread Tags Are Permitted In Lucee 5.3.2.77

  Posted on Jul 17, 2019 at 7:59 AM

  @Gert, The parallel thread stuff has been really interesting to play with. I actually have an experiment in production in which 50% of requests to a particular workflow are using Struct-based parallel iteration around database access. The concept is really exciting; but, I am discovering t... read more »

  @Abu, Yeah, this is really a topic that I need to start using more. Right now, it's been largely theoretical for me.... read more »

• Using The String localeCompare() Method To Implement A Natural Sort In Angular 8.2.0-next.0

  Posted on Jul 15, 2019 at 8:18 AM

  @Charles, I feel like I had an algorithm like that for something in the past. I vaguely remember having to sort arrays-of-arrays, where each array index needed to be compared to the same index in the other arrays. I can't for the life of me remember what it was for -- but, I remember the ... read more »

• The CFQuery Tag Supports Silent Asynchronous Query Execution In Lucee 5.3.2.77

  Posted on Jul 15, 2019 at 8:12 AM

  @Zac, I can dig it. I know that I've been a bit confused about how to file bugs in Lucee in the past. I vaguely remember hitting some sort of login-wall in the past where I had to have a JIRA account or something to file a bug. Will take a closer look when I have a moment.... read more »

• Caching Function Outcomes With CachedWithin Caches Both The Return Value And The Output Buffer In Lucee 5.3.2.77

  Posted on Jul 15, 2019 at 8:11 AM

  @Charles, Hmmmm, I have no idea :D I assumed they were the same thing. I have yet to see an example of echo() that didn't feel like a drop-in replacement for writeOutput() . I just thought it was a shorter alias.... read more »

• The CachedWithin Function Memoization Feature Appears To Compare Complex Objects By Value In Lucee 5.3.2.77

  Posted on Jul 15, 2019 at 8:09 AM

  @Chris, Yeah, the {} / [] one is strange. I wonder if it's using some sort of Java hash-code under the hood and these evaluate to the same hash-code? To be honest, I don't really know much about Java. Re ?? , I think the problem is that my blog-code is so old, I never configured the d... read more »

• I Can Finally Embed An Assignment Operation Inside Of Other Expressions In Lucee 5.3.2.77

  Posted on Jul 15, 2019 at 8:06 AM

  @Charles, Ha ha, to be clear, this isn't just for return statements. Another common place that I use this in JavaScript (at least) is in things like a while() loop: while ( value = someFunction() ) { // .... } Here, there is an assignment inside the while() condition expression... read more »
