• Performing An In-Place Natural Sort On An Alpha-Numeric Array In Lucee CFML 5.3.6.61

  Posted on Aug 6, 2020 at 8:22 AM

  @Seb, That's a good point. To be honest, I go back and forth about how I feel about it because there's decimal numbers like: 3.145 But, then there are also strings of numbers that happen to contain decimal-points, like IP addresses: 127.0.0.1 These two types would / could f... read more »

• Fat-Arrow Functions And Lambda Expressions Are Supported In Lucee 5.3.2.77

  Posted on Aug 6, 2020 at 8:16 AM

  @All, In this post, I implemented the "natural sort" using an intermediary array, which means that the original array and the sorted array are two different objects. Yesterday, I needed to implement an in-place sort using a natural sort order. So, this morning I took a look... read more »

• Using A Task CFThread To Run And Restart Daemon CFThreads Indefinitely In Lucee CFML 5.3.6.61

  Posted on Aug 3, 2020 at 6:49 AM

  @All, I thought it was kind of interesting pattern to expose a Function on the Thread scope that I can then call across page-requests. I figured I'd break that out into its own post: https://www.bennadel.com/blog/3871-using-a-closure-to-terminate-cfthread-tags-across-page-requests-in-l... read more »

• Using A Task CFThread To Run And Restart Daemon CFThreads Indefinitely In Lucee CFML 5.3.6.61

  Posted on Aug 3, 2020 at 4:54 AM

  @All, Ok, it seems that setting the requestTimeout within the Task thread will successfully allow the daemon threads to live longer. In a subsequent experiment, I went back and updated my Task thread to look more like this (the important bits have ****** around them): thread ... read more »

• RequestTimeout Setting Affects CFThread Execution In Lucee CFML 5.3.6.61

  Posted on Aug 3, 2020 at 4:42 AM

  Ahhhh, d'uh. My initial attempt to use the CFSetting tag was trying to use the createTimeSpan() function for the requestTimeout . It's been a long time since I've even used this tag. But, it doesn't work that way :D You have to provide a number of seconds , not a time span . When I ... read more »

• RequestTimeout Setting Affects CFThread Execution In Lucee CFML 5.3.6.61

  Posted on Aug 3, 2020 at 4:36 AM

  @Elliott, Hey man -- long time no talk :D Good to hear from you! I'm actually trying to use this approach right now in my previous exploration on using Task threads. Initial findings are a bit confusing - originally, my threads were seemingly "completed" at about 30-seconds. Bu... read more »

• Using A Task CFThread To Run And Restart Daemon CFThreads Indefinitely In Lucee CFML 5.3.6.61

  Posted on Aug 2, 2020 at 5:58 AM

  @All, So, as I was exploring Task Threads, what I noticed is that the spawned CFThread tag was mysteriously dying at about 30-seconds. And, after poking around, I noticed that the request timeout in the Lucee Server Admin was set to 30-seconds. I can't believe I didn't already know ... read more »

• Using CSS Host-Context To Theme Components In Angular 6.1.3

  Posted on Jul 31, 2020 at 7:57 AM

  @Marçal Juan, I believe you are confusing the native :host-context() with the concept in Angular. When Angular compiles this CSS, it doesn't actually leave :host-context() in the CSS code - it changes it to be simple selectors. So, for example, in my AppComponent LESS file I have: :... read more »

• Testing wkhtmltopdf 0.12.6 With Docker In Lucee CFML 5.3.4.80

  Posted on Jul 28, 2020 at 12:28 PM

  @Art, I think a lot of people use some sort of headless-Chrome for this type of thing. Just the other day, I was talking to someone who does that via a Lambda function on AWS. If I were to write this in Node.js, that's probably the way that I would go. But, it's fun to see what ColdFusion ... read more »

• The Double-Bang (!!) Operator And A Misunderstanding Of How JavaScript Handles Truthy / Falsy Values

  Posted on Jul 28, 2020 at 12:27 PM

  @Mitchell, Oh, that's a really interesting point re: Boolean() as an Object vs. a cast-value. I knew there was a major difference between the two; but, I couldn't quite remember what it was.... read more »

• Copying Slack's Brilliant Virtual Scrollbar And Overflow Container In Angular 9.1.12

  Posted on Jul 28, 2020 at 12:26 PM

  @Hassam, Yeah, I really like this for that reason - we get so much right out of the box with this approach. We only have to "patch" the dragging of the "thumb" (which most people don't do anyway since most people are using scroll-wheels and magic-mise and things of ... read more »

• ColdFusion Components (CFC) vs. ColdFusion Closures Performance Exploration In Lucee CFML 5.3.4.80

  Posted on Jul 28, 2020 at 12:24 PM

  @Chris, The variables scope is the "private" scope of the ColdFusion component. So, anything that I put in the variables scope is inaccessible to the outside world and can only be accessed by component methods. Conversely, the this scope is the "public" scope ... read more »

• Using Negative Box-Shadow Spread To Communicate Depth In CSS

  Posted on Jul 28, 2020 at 12:22 PM

  @Ted, Yeah, it's super subtle . I didn't want to make it too large or I thought it started to look a little odd (but would have been more obvious). I think it's a cool thing; however, I am not sure how often I will have elements "come off the page" to the point where this will m... read more »

• Using Apache POI 3.17 To Save InVision Prototypes As Interactive PowerPoints In Lucee CFML 5.3.6.61

  @Andreas, Thank you -- I'm glad you found it interesting. The POI library is pretty nifty!... read more »

• Using Dynamic Template-Driven Forms In Angular 7.2.7

  Posted on Jul 24, 2020 at 7:31 AM

  @Dilip, I'm having a little trouble understanding your context, so let me see if I can echo what I think I am hearing: You have some sort of multi-row Product selection. And, there's a drop-down for the Product. And, when the user selects a Product, you want to show the associated Price ... read more »

• Using Dynamic Template-Driven Forms In Angular 7.2.7

  Posted on Jul 24, 2020 at 7:22 AM

  @Ambareesh, I am not familiar with the .setValue() function. I think that may be more relevant for reactive forms , not template-driven forms. With template-driven forms, you should just be able to define your "view-model" and then the HTML templates will just update to reflec... read more »

• Thinking About Boolean Arguments As A Code-Smell In A Legacy Codebase

  Posted on Jul 24, 2020 at 7:18 AM

  I mean, yeah, we all do this to some degree right? At the end of the day, you gotta ship product ; and, we don't always have time to make things the way we want. In fact, just yesterday, I put this comment in one of my CFCs: <cfscript> // NOTE: Honestly, I don't feel great about c... read more »

• Looking At Different Click-To-Edit Implementations In Angular 9.1.12

  Posted on Jul 22, 2020 at 3:29 PM

  @Charles, It's TypeScript specific; but, you wouldn't need it in vanilla JavaScript since it's just the compiler complaining about the "possibility" of a null value, which you don't have to worry about in plain JS.... read more »

• Looking At Different Click-To-Edit Implementations In Angular 9.1.12

  Posted on Jul 22, 2020 at 12:40 PM

  @Charles, It's TypeScript's Non-Null Assertion . It essentially says that the expression up to that point will not be null . The reason I had it in this case was because the this.selectedProject was set to null | Project , so TypeScript would complain that it could be null . Bu... read more »

• Copying Slack's Brilliant Virtual Scrollbar And Overflow Container In Angular 9.1.12

  Posted on Jul 20, 2020 at 4:34 PM

  @Charles, I think the real moral of this story is that if you see something that looks slightly out-of-the-ordinary, it pays to pop-open those Chrome dev-tools and take a look at what is going on. The only reason I even thought to look at Slack's implementation was because the scrollbar ... read more »
