Goldenseal Pro- Completion Estimate (Jul 27)

I recently came across an article explaining why it’s hard to estimate programming projects. Still, our users want to know when our Pro update will be finished, and we do too. It’s worth a try, even if the effort is guaranteed to be flawed.

March was the last time we estimated a completion date for Goldenseal Pro, and that predicted mid-October. We just updated the data. The revised spreadsheet also calculates mid-October, but only for the Mac version of our new accounting software. It adds another 2.5 months to finish the Windows version.

It’s still very much a guesstimate. The work in our code is going about as expected. However, occasionally the Cocoa framework throws a curve ball. When that happens, it can take a few extra days or weeks, to finish something trivial. If there are a lot more curve balls, the work could easily drag on a few months longer. It’s an unknown unknown. We really won’t know what we don’t know until it’s over.

Some of the prep work for the Mac version will probably make the Windows update go faster. It’s even possible that Windows part of the estimate is too conservative. But the MFC framework does throw a few curve balls of its own. Those are the main uncertainty.  However, on the whole it is just less complicated to program for Windows. It definitely will take less time than the Mac.  Working with the Cocoa framework is difficult.

Apple has a Cocoa listserv, mostly viewed by developers building software for Mac and iPhone. We have posted a few questions there when stumped. Usually, the other programmers are stumped also. The list does not get much traffic. Likewise, Stack Overflow and other programmer exchanges have few recent posts for Macintosh Cocoa. Nearly all recent questions are for Swift and iOS.

Apple is ending support for Carbon and 32-bit apps in 2019. You would think there would be more developers in our position: rewriting and updating existing Carbon apps to use Cocoa. On the other hand, there were many Mac programs that did not survive the transition to OS X. Moving to Cocoa is even harder, so many developers may have decided to retire. In all honesty, if we had known 3 years ago how difficult Cocoa was, we’d have thrown in the towel then, also. But, our staff is now close enough to completion that it would be absurd not to finish.

I did remodeling work for an accounting professor who had a clever explanation for why people under-estimate projects. Essentially, one big difference between humans and other mammals is that we look further ahead. Building a house or a dam might take 10 years to break even, and no other species would make that gamble. Beavers and apes do a bit of long-range planning, but only on a span of months.

Human brains could have developed stronger foresight, but evolution is random. It uses the first thing that works, even if inferior. So, maybe humans brains just adjusted by under-estimating the cost of big projects, and over-estimating the rewards. Delusion has the same result as wisdom.

Anyhow, Goldenseal Pro looks much better than the current version. It will be good in the long run. It’s good that we were deluded.

Goldenseal Pro Alpha #2 (Jul 19)

This week we are finishing up the last interface details in the main window for Goldenseal Pro. We like how it looks, so it’s time to release the second alpha version. To download it, click here.  It runs on Mac OS 10.11 (El Capitan) and newer.

We still are not using it to run TurtleSoft, and this version is definitely not ready for actual use. But there are two things you can do with it, that will help us (and you).

First of all, please check out the new interface, and let us know what you think of it. There is still time for us to make changes or improvements. It’s easier now, than later.

Secondly, please try converting your company file to the new format, and let us know if there are any problems. That way, we can fix them before final release.

Follow these steps to run the conversion:

  1. Just to be extra careful, make a backup copy of your current company file.
  2. Add .glds to the end of your company file’s name, if not already there.
  3. Download the alpha version if you haven’t already done so.
  4. Double-click on the zip file to decompress it (if your browser didn’t do that automatically).
  5. Open the GS-Pro-Alpha folder, and double-click on the GS-Pro-19-Jul-2018 application icon.
  6. If your security settings give a warning about an unidentified developer, right-click on the app icon, and choose Open.
  7. When it asks you to open a file, locate your current company file, and open it.
  8. The app will ask you if you want to convert to the new format. Click OK.
  9. The app will ask you to save the new file. Give it any new name, choose a convenient location, and save it.  Your current file will not be changed.
  10. It will take a minute or two to convert your data to the new file format. When the conversion finishes, you’ll see a report of what happened, and any problems that occurred.
  11. Choose Quit from the Goldenseal menu.
  12. Double-click on the new file to open it. Take a look at the new interface. Let us know what you think of it!
  13. If you experienced any problems with the conversion, please let us know!  We will fix them, and make sure your file can be converted before the final release.

Goldenseal Pro Progress- Tab Order & Open Source (Jul 13)

When viewing records in accounting software, it really helps if you can tab from field to field. That way, users can keep their hands on the keyboard while doing data entry, with no need to click in each field.

For the current version of Goldenseal, we wrote our own tabbing code, back in the late 1990s. It wasn’t too hard. Each window already stores a list of fields in front-to-back order. When you hit the tab key, it finds the current field, looks through the list for the next editable field, and selects it. For shift-tab, it looks in the other direction. Tabbing in tables is a bit more complicated, but not by much. The entire system took about one programmer-day to build.

Last week, we started to set up tabbing in Goldenseal Pro for Macintosh. The Cocoa framework includes an automatic tab system. They even brag that “you don’t have to write any code” to make it work. We turned it on, but it didn’t work.

Next attempt was Cocoa’s manual tabbing system. It uses what’s called a linked list. Each field is linked to the next field in the list, until you loop back from the last to the first. We set that up in Cocoa, but it still didn’t work. We read Apple’s documentation and checked Stack Overflow, but found no answers. We searched for a sample project with tabbing, and didn’t find any.

Next, we tried stepping through the tab process in the debugger, to see where it was failing. Unfortunately, Cocoa is very much a “black box”. Unlike the other frameworks we have used, it has no visible source code. The debugger only shows machine instructions, which are usually too low-level to be helpful.

When that failed, we went back to our previous approach. Go through the list of fields, and find the next one. To make that work we have to intercept the tab key, and then highlight the next field. Those both turned out to be difficult tasks in Cocoa.  Eventually it worked, but it sure wasn’t easy. Altogether, it probably took a programmer-week. The only good news is that some of what we had to learn will be useful for other things.

Apple’s Cocoa framework is the only major framework that hides its source code. It’s definitely an impediment. We have been working with Cocoa since September 2016, and it’s definitely the hardest framework our staff has ever experienced.  A while back we calculated an October 2018 completion date, but that probably will be pushed back a few months. The only good news is that Cocoa is hard for everyone, not just us. When the Mac goes entirely 64-bit in 2019, a lot of our competitors will be gone.

Ironically, Apple’s Unix operating system code (Darwin) is open source.  That means its source code is not only visible, but editable by qualified developers. Unfortunately that doesn’t help us, since our type of programming entirely relies on Cocoa.

Speaking of open source, it’s an option we are considering for Goldenseal’s code.

Goldenseal Pro Progress- Right Clicks & Extra Windows (July 2)

Goldenseal accounting software was designed for a one-button mouse. It’s all that was available for the Mac back then.

Goldenseal Pro is modern, so we can also use the scroll wheel and right-button. Last week we started on the first of the right-click commands. They are a much better way to access some details. For example, when you click the popup button next to a clairvoyant field in the current app, you’ll see a few options down at the very bottom of the menu. They let you enter ‘none’, edit the selected item, or add a new one. A few specialty fields add other options.

In Goldenseal Pro, you access those commands with a right-click. It’s much easier to find the commands (especially when the list is long). Right-click menus are easy to program, so we’ll be adding them in other useful places.

When you click the popup to edit or add a record, the current Goldenseal opens a modal dialog. It’s a separate window that takes control until you hit OK or Cancel. Modern versions of Mac and Windows both use drop-down panels instead. Panels work the same as the old modal dialogs, but they are attached to the current window. That makes them easier to find, and more logically attached to what you are already doing. Goldenseal Pro uses panels for almost everything that used to be in a modal dialog.

There are many places in Goldenseal where we show linked records. For example, in a Project account you might click a button to see Material Purchases for it. When you pay for a purchase, it shows the Bank Transaction that pays for it.

The current Goldenseal opens a separate window for linked records. The end result is often a bunch of different windows scattered about. Our own TurtleSoft file usually has 10 to 20 windows open. It makes the screen very cluttered. Eventually we close them all, but the clutter soon returns.

For Goldenseal Pro, we can use panels to show linked records, or tabs in the main window, or separate windows. As we start to use Goldenseal Pro to run our own company, we’ll be experimenting with different setups. It may be something that we control via Preferences, or by right-click options.

That part of the interface programming is going well. Unfortunately, the bad news is that Apple has decided to discontinue drawers as part of the Mac interface. The code still works, but it is deprecated and will stop working in some future version. Drawers are an additional type of window that slides out from the side, to show extra details. They are (were) perfect for showing breakdowns. We are still looking for a substitute.
