Wasn't expecting that: made another release of FileSieve yesterday.
For no particular reason at all, a thought about the way FileSieve handles the
I had a feeling of dread. I wasn't sure why, but it was there. Something was... wrong.
When my conscious mind caught up with the sub-conscious, it occurred to me: profile processing (which is what
An enormous oversight as this means FileSieve is merrily executing commands while a profile is being processed, copying files and all sorts of stuff, while possibly nobbing things up left and right.
Loaded the code and then wondered how I was going to solve this. I forewent any semaphore or signalling as I wanted to get this update done and released ASAP. Instead, I made all automation commands asynchronous and then, in simple terms, busy-waited until it was complete.
I'm cheeky, me!
While I was in there, I decided to add support for allowing automation via an external file. FileSieve parses the file and then runs the encountered commands as though they were passed in via the command-line; lovely, lovely, code reuse.
As the file reading code is custom just for that task, I thought I'd allow line comments; any line that starts with a hash # character is ignored. Incidentally, all lines are trimmed of spaces.
Commands and their values can be spaced out however you want as, again, trimming is done before the fields are interpreted. As well as providing general flexibility in the syntax, it also avoids the commands/values looking all squashed together.

Comica Database Update
Oh my, no update for a few days? It's the end times!
Nah, nah; I just didn't work on anything of note to write about. Already, a lot of the stuff I blog about I would never have previously done as they're not what I'd call "major", or even exciting. But I'm making myself talk about them anyway as it keeps content coming, so don't go thinking I'm thinking that I'm working on major works of art or anything - it's just more kahnent to babble about.
Alright, Comica. Not much to report on this other than I pushed a database update out for the first time in a while. Or, at least tried to.
I received a "Comic not working" notification (a feature I built into Comica that allows users to notify me of knackered comics) and thought, "Eh - why not?". I then ran a "deep validation" within the Comica Editor to weedle out any obviously broken comics while I was fixing up the reported comic.
Thirty minutes later (yes, it takes a while to manually go through the comics that the Editor says is broken; this is why I don't do full updates often, especially as I could be working on my commercial software instead), all fixed. Hit Upload and... nothing. The little console app that does the actual uploading appeared and then immediately disappeared. Uh-oh.
Loaded up the source and, oh, I should probably upgrade all of the projects to .Net 4.7. Did that and realised the configurations (x86, x64) were all over the place; there were even Itanium configs in there for some reason. Cleaned it all up.
Stuck a break point in the uploader source and immediately found the problem: the computer name it was expecting was different, so it bailed out.
When I created the Database Uploader console app, I put a quick 'n dirty check in there to ensure that it only runs on my PC. Turns out I hadn't changed the name of the PC when I installed Windows a couple of months back.
Fixed that and everything ran as before.
This got me thinking about doing a bit of work on the "next generation" of Comica (the editor is really nice!) - except it would have to be free, and then the thinking stopped right there. Ya can't live on free, son.
As an excuse to use this new keyboard, I was going to rewrite a part of the FileSieve documentation but then I realised I didn't do a blog post for today. So here I am.
Today was spent working on FileSieve and getting command-line automation happening.
As part of my App Framework library, the Parameters class provided all the functionality I needed to get things moving fast. It was simply a case of reiterating over the
Due to this iterative nature, FileSieve can executes multiple commands from the command-line in sequence. So, for example: you can select a profile, start it, and then select another profile and start that, even making changes to it - and only it - beforehand.
The first added command was
This makes the GUI select the My Profile profile and make it active. All following commands are then executed on that profile.
Most of the commands emulate using the application's interface, such as
I did wonder about adding generic automation to the App Framework for all of my software, but it'll still take manual work to specify what's what. Probably isn't worth it, to be honest. Although I think Wake On LAN Ex will benefit from automation.
The 4.22 release will feature additional commands that aren't critical to using FileSieve from the command-line.
Oh, speaking of the command-line: the nomenclature has been changed from Command-Line to Automation. The reason being that I'd like to also add support for automating FileSieve usage via a text file. It'll basically be a top-to-bottom list of commands and parameters that FS iterates through executing one at a time.
To help with any debugging issues on the user's part, all automotive actions and their outcomes are logged under the
FileSieve 4.21 is available from FileSieve.com.
I was supposed to be doing smallish posts for this blog and so setting pagination to 40 posts per page seemed like a good number.
Except it didn't turn out that way; the posts are tending towards pretty large and so 40 posts was way too much. Far too much vertical text.
So I changed it to 20.
And then sorting broke.
When I originally started this blog rewrite, I couldn't get the posts returned in exactly the correct order due to the way collections et al work in Laravel, and I finally ended up doing a reverse() within the actual Blade template that displays all of the posts.
I then made changes to the Controller to reverse the results and in combination with the pagination, it went a bit... weird. Some more tarting around later yielded nothing helpful.
I remembered the stupid reverse(), ripped it out and - tada!
Now pagination is set to 10 posts per page.
Assembler, part 7
Haven't quite gone ahead with actually executing instructions as yet because I re-worked the way a "machine" is implemented.
I ended-up ripping out the hard coded properties and features and made everything generic. There's now a set of

Anyway! If you wanted to add 8 Data registers, you'd do the following:
This will create 8 registers, all named D0 to D7. Basically, the index is applied directly after the base name.
Do CPUs only really have (general purpose) Data and Address registers? Could I replace the literal with an enum, instead?
Fetching a register? Like so:
With name being, say, "D6" to get the sixth Data register.

Okay, okay; can't put off doing the operand parsing any longer if I want this project to progress any further.
Just like the (incomplete) line-by-line parsing of the entered sourced, I'm going with Regular Expressions. Everything is going to be regular expressions; regular expressions all the way down.
As there's no specific reason why the

Logitech G19 and the Corsair K95 RGB Platinum Mechanical Keyboard
After forcing myself to use the Logitech G19 keyboard for the past two years, I've finally booted it right up the arse and replaced it with a proper mechanical keyboard. A Corsair K95 RGB Platinum (click here for US version).
I kept with the G19 because of two reasons.
I still found myself reading about mechanical keyboards every few months and which switches were the best. Incidentally, the Cherry MX Blue switches sounded like my kinda thang.
The other day I decided enough's enough, and I'd go ahead and buy a mechanical keyboard at long last. It arrived today, and I realised something: the Like A G19 app will be forever retired without anyone else ever seeing it. Hmm, can't really be having that.
I quickly made some source changes, wrote a
This is the first and last public release; unless someone gives me a big stack of cash, I'll no longer be updating it and I won't be releasing the source. The last twenty years have proven to me that releasing software for free is a terrible idea. I've also released source to applications before and nothing good ever comes of it, either. Anyway, it's tied in with my other libraries - source of which I'll never be releasing.
If you have a Logitech G15, G510, or a G19, and you'd like to make the built-in LCD a bit more than absolutely freakin' useless, take a look at Like A G19. It's free, but it's woefully incomplete. Reading the included
Anyway, this K95 RGB Platinum? It's awesome. Weighs in at 1.35KG due to being made of aluminium and absolutely solid. The only issue though is that I personally wanted Cherry MX Blues, as I said above, but it only comes with either MX Brown or MX Speed. I chose the Brown, but I would've loved the clicky Blues. Oh well.
Oh, and as a bonus: I'm now using a proper UK layout. It turns out the G19 had a US layout, which meant the Enter key was only single height as opposed to the double height of a UK layout. Very annoying as I was never really able to get used to it even after a couple of years.
Below is a photo of the keyboard, along with the WASD key-caps that I changed - they're included in the box along with a key-cap puller and additional QWERTY caps. They're sloped and have a textured finished.
While I was fixing up an application that I hadn't worked on in a while, I noticed that it linked to a donation page on the previous blog. A donation page that no longer existed when I revamped things; I've just been sorting that out.
There's now a dedicated donate page and a link to it at the top of this very page.
I'm honestly not really expecting much from it as my software was donation-ware for almost 20 years and, well, it didn't exactly go very well. This forced me to finally start writing commercial software and stop giving it away for free. Well, there are "free editions" available so they can still be used for free if you don't require the more advanced features (and aren't particularly bothered about supporting the software). I couldn't bring myself to put the software entirely behind a paywall.
(Incidentally, this is why there isn't a "next generation" of Comica as I can't really charge for it and I can no longer give away software for free)

On the interface side of things (c'mon, like I can resist UI work) the syntax highlighting now colourises the datatype (or size as is the actual term) for mnemonics. Turned out this was achievable via making the datatypes an operator when it comes to highlighting as they don't need to be on word boundaries - thanks to Rob for the suggestion. Still more highlighting work required.
The Registers window now has a trace of what it parsed from the entered source code and displays the interpreted code. Changed the font to a mono-space one as the other just looked messy when registers' widths didn't line up. Sorry Segoe UI - not this time.
