Xojo 2017 R2.1 and Updated Roadmap

I’ve had a hellacious travel schedule the past six months so I apologize that I’ve not been up to snuff on Xojo news. Last week Xojo 2017 Release 2.1 was made public and earlier this week Xojo CEO, Geoff Perlman, penned a blog post about the short-term roadmap for Xojo. Let’s dig in!

First, the 2.1 release has a mere 16 bug fixes in it. This dot release fixes some critical Linux, and Windows bugs. A few IDE bugs were addressed and the PostgreSQLDatabase plugin was updated. Many of these bugs won’t affect everyone but it’s definitely worth upgrading from R2 if you have not already done so.

Now on to Geoff’s short-term roadmap. You can read the entire blog at https://blog.xojo.com/2017/09/19/the-short-term-xojo-roadmap/. To summarize it in a nutshell: 64-bit is taking them longer than expected.

To this I say, ‘Duh’. Anyone who expected 64-bit to be done by this time hasn’t been around very long. Xojo has consistently blown their estimates for most (all?) of their big projects. The transition to Cocoa from Carbon took a lot longer than originally announced. iOS took longer than expected. The introduction of the Xojo IDE from the Real Studio IDE was also delayed (as a side note I’m still amused at the accusation that I personally caused a 6-month delay in the Xojo IDE due to a blog post).

The point isn’t, ‘Oh my gosh, Xojo has yet another delay’ it’s that Xojo is very bad at estimating this stuff. Some of this is on them but some of it is beyond their control. Supporting mac OS, Windows, Linux, iOS, Raspberry Pi, desktop, console, and web apps is a mammoth undertaking. I am constantly amazed at the magic Xojo performs without my knowledge. To me it ‘just works’.

Apple, bless their hearts, changes things on a whim every year at a minimum (sometimes even more often than that) and causes Xojo to play catch up. And they usually do this with little notice. The current change being that the iOS Simulator will no longer support 32-bit apps so guess who has to scramble to make it work now?

Linux distributions seem to change daily. Xojo has to scramble to catch up with those changes too. They recently updated Xojo to use GTK3 and that was a big deal. They sort of had to do this upgrade because GTK2 was pretty long in the tooth. I can only imagine the internal efforts they did for testing.

Windows doesn’t change much for better and worse. The technology from ten years ago still works but that’s not necessarily the best ‘modern’ approach for Windows. Many users complain about flicker when windows are resized. This is a valid complaint but because Windows does not double-buffer their windows like Mac and Linux the older Win32 controls flicker like mad under many circumstances.

Regardless, 64-bit is the roadblock for other things. If you were hoping for Android, interops, or plugins compiled in Xojo to be released in 2017 you’re out of luck. This is what happens with a small development team. There simply isn’t enough man-hours to work around delays in some projects. This happens in ALL software development products but with a small team this impacts everything.

The only bit of good news from Geoff’s blog post is that the Windows framework is getting a big update. This update will ‘dramatically’ reduce flicker according to Geoff. No word on what exactly they’re changing though a thread on the forums from Aug 9 might give a little clue. Changing transparency seems like a little thing but perhaps they plan on implementing a double-buffering scheme. Until we find out more it’s not worth speculating. It seems like this new scheme might make it by the end of this year. So either this has been in the works for a long time or it’s not huge from a coding standpoint.

Promising services based on a product feature that doesn’t yet exist is dangerous. If you were promising Cocoa, iOS, or 64-bit versions before they were actually released you did your customers a disservice. I remember one XDC where a database ORM (Object Relational Model), similar to ActiveRecord, was shown with a lot of interest by those attending. I’m still waiting on it. The lesson is to not depend on vaporware!

So what are your thoughts on R2.1 and the Short-term Roadmap?

Xojo 2017 Release 2

Last week Xojo 2017 Release 2 hit the download servers. This release has the usual mix of new, changes, and bug fixes. At first blush it doesn’t seem like there is a lot to mention but there is, but I’ll get to that in a minute.

Before we get into the highlights it’s worth mentioning, again, that R2 does not have 64-bit debugging for Windows. As Xojo mentioned in their blog post (http://blog.xojo.com/2017/07/26/the-best-laid-plans-64-windows-debugging/) the LLVM compiler and toolset just wasn’t ready to be included in R2.

Despite the lack of a 64-bit debugger for Windows a number of things were corrected in 64-bit Windows builds. Icons are now applied correctly and they also show the correct version information. The 64-bit MS SQL Server database plugin now works when compiled on the Mac. Game Input Manager also works in 64-bit now. Images assigned to an ImageWell are now drawn properly.

Also related to 64-bit builds, the Split and Join functions for Unicode strings is much faster and Replace and ReplaceAll behaves like the 32-bit versions. Exceptions no longer leak memory. Virtual Volumes now work. Copying a picture to the clipboard now works. XojoScript is now available in 64-bit builds.

Linux GTK3. See Xojo blog post (http://blog.xojo.com/2017/08/15/goodbye-gtk-2-hello-gtk-3/) detailing some of the changes. The switch to GTK3 was necessary for HiDPI support and now scales automatically on integral scale factors (i.e. 1x, 2x, 3x, etc). This also lets child controls clip properly on parent controls whereas they did not always clip properly in prior versions.

Be aware, though, that this switch may affect how your controls draw. While it’s always been true that default control sizes are bigger in Linux you could sometimes cheat and use the open events (or subclass the controls) and make them slightly larger in Linux and perhaps make the system font a little smaller and things would look good enough to not require a bigger UI change. With this switch to GTK3, however, it seems like some controls, PopupMenu and Pushbutton come readily to mind, in that their caption location is definitely lower than the prior version thus making them look odd without more work. For me, what worked in R1.1 just doesn’t look good in R2.

This change begs the question that if we could make a Xojo theme for Linux that would make control heights smaller, text sizes smaller, and change the caption locations to make this a non-issue. Perhaps someone with more knowledge about Linux themes could answer that.

A few other things that might ruin your day in Linux is that not all Linux distributions now allow you to remove the border of TextFields. It wouldn’t surprise me if additional issues are found in GTK3 as time goes on.

iOS has a couple of important changes. The first is that the AutoLayout Priority property in prior versions was calculated on its own. In R2 new constraints get the ‘Required’ priority. Any existing projects should get thoroughly tested on multiple sized devices to make sure nothing needs to be fixed. In our own testing we had to simply change the priority to Required to fix any issues.

Another iOS change that may affect you is that setting the CopyFileStep to the “Frameworks” destination now properly creates the Frameworks folder inside the iOS package and puts the files there. Before you had to create a manual directory for it to work properly.

Another nice fix is that a numeric suffix is no longer added to copied iOS controls unless they need it. This was an annoying bug. Not hard to fix but annoying nonetheless.

The web framework received some attention in this release as well. The WebPage width and height properties are now correctly updated before the Shown event is fired. A number of WebMapViewer errors were fixed including an annoying JavaScript error on the first refresh and where it would fail if there was more than one instance used in the app at a time.

The Session timeout now takes touch events into account when figuring out the last interaction with the app. In addition to that, web apps now try to reconnect if they’ve lost connection to the web app and will continue to do so for three minutes or until the user navigates away from the disconnect screen.

The Listbox control received some updates. For Linux, HelpTags are now positioned properly and in Windows they disappear properly when the mouse leaves the control Also in Windows the endcap is drawn correctly and headers no longer flicker when hovered over by the mouse or when clicked on.

A regression was reported for R2 that affects dragging items to the Listbox. In Windows the X & Y coordinates are incorrect. This was reported in Feedback 49190.

New Drag events were added to the Listbox. Except for a jumbled paragraph in the release notes I’m not sure anyone would notice. I would spend more time talking about it but as far as I can tell these are not documented in the Language Reference, either local or online and there is no example. I find it inexcusable to have a major change to such an important control not be documented. This seems like it should automatically make it into the documentation. Do better Xojo!

The IDE received a bunch of bug fixes and changes. New items in the Menu Editor no longer ‘fly in’ and arrow keys work now. Long error messages are wrapped and row heights adjusted in the error reporter are adjusted as needed (as a side note does this forebode variable height list boxes?) Recent Items in the Project Chooser now show size, date created, and date modified when possible. Pressing the Escape key now acts as a “Revert Now” to changes.

It also appears that a regression bug was introduced in Raspberry Pi. Button.Action events don’t fire if using a touchscreen. They appear to work properly when using a mouse. Feedback 49221.

As always, look through the release notes to see what else has changed. It’s also a good idea to test your applications thoroughly when upgrading to a new version.

Xojo 2017 Release 2 was chock full of new things and changes. I hope a dot release is issued to fix some of the bigger regressions. Up next is 64-bit debugging and remote debugging, the new plugin format, interops, and Android. Think they can get it all done in 2017?

Sorry for the delay in getting this out. Those pesky clients sometimes want on-site help and the last thing I feel like doing is writing after a long day of coding.

 

Software Development is Fluid

Software development is fluid. Some bug fixes and feature requests that seem simple are often not so simple, or, take a lot longer than originally thought. Some that seem like they’re hard are not, or, take practically no time at all. What’s worse, is that sometimes you don’t know what the level of effort is until you start the work.

Historically, the only way to know what future feature sets will be in Xojo is attend a Xojo developers conference where the CEO of Xojo, Geoff Perlman will sometimes tell us what’s coming up. These announcements are almost always preceded with a “we expect to release that feature in this timeframe.” It’s smart because he knows that software development is fluid.

The problem is that what we hear is, ‘Release X will have this feature.’ We hear a promise despite all the hedging made by Geoff. Like every user I want that feature now and there are times that I need that feature to sell some work. I think it important to remember that when selling any work you have to use the current (and proven) technology instead of what’s coming up.

64-bit Remote Debugging in Windows comes to mind. Geoff at last years XDC said that in the first quarter of 2017 Remote Debugging will be available across all platforms. In Berlin in May he said Release 2. Well, as they said in their blog post at http://blog.xojo.com/2017/07/26/the-best-laid-plans-64-windows-debugging/ this isn’t going to happen for 2017 Release 2. Apparently the LLVM compiler and toolchain isn’t ready for primetime yet. So instead of giving us a buggy (and probably unusable Remote Debugger) they pulled it.

I understand and applaud the decision. Software development is fluid and some things are out of their control. Since Xojo is not in charge of the LLVM compiler and toolkit for Windows they are at the mercy of other developers. It stinks but that’s just the way it works.

I know that some of you will jump on the ‘let’s criticize Xojo’ bandwagon and you have every right to do so. However, keep in mind that they do hedge their announcements with ‘we plan’ or ‘we expect’ to do x by this time or this release. If we want to get any information out of them about future plans we need to cut them some slack. They have zero obligation to tell anyone about their long-term plans.

What Xojo does is magic. For a vast majority of Xojo users it ‘just works’ on every platform they target. It’s been a long time since I’ve had something work on one platform and not on another (that wasn’t my own fault). Think about it: Desktop, Console, and web apps for Mac, Windows, Linux, and Raspberry Pi just work with a simple checkbox. iOS applications are different and use the new framework but I expect Android (promised by end of year) to be very similar (if not identical in most respects). And let’s not forget 32-bit and 64-bit apps just work too despite 64-bit being a relatively new target.

Software development is fluid and every year Xojo has to deal with whatever Apple, Microsoft, Raspberry Pi, all the Linux distributions, and all the browsers throw at them. I’d say they’ve earned some slack from us users. I’d rather have a release that works than one that doesn’t (I remember some that didn’t work).

Does this mean we should stop criticizing Xojo? Pft. Please. The day I stop criticizing Xojo is the day I stop using it. It is our responsibility to keep reminding them of what we need. A long standing criticism are bugs that have been reported and have been around a long time. But yet every release has many dozens of fixes so they do fix a lot of bugs. The one’s that are hard to excuse are new features that have obscure bugs that last multiple releases.

Some of the criticism must be on us users. We don’t always report bugs. Never assume someone else has reported it. Always try to give them an example project demonstrating the bug. Xojo has some responsibility for this, too, as Feedback hasn’t always worked for some users. This is part of the give and take of a software development tool company and its users. We need them and they need us.

So yes, it stinks that 64-bit Remote Debugging isn’t available for Windows yet. And you’ll note that they’ve not said when it will be available. We can hope that it will happen for Release 3 but until the next beta round we won’t know for sure. I expect that all of their other plans for 64-bit are probably delayed too. A 64-bit IDE might be a few releases away. We don’t know what this means for the new plugin format, or Android, either. Software development is fluid so go with the flow until we see something solid.

Happy coding!

Automating Xojo Database Development with ARGen

Database applications are relatively easy with Xojo. The native Database, DatabaseRecord, and Recordset classes make it easy to connect, add, edit, and delete data in your console, desktop, and web applications. What we’ve found over the years isn’t that it’s hard to create these applications but that it’s tedious and also the very nature of Xojo tends to make life more complicated. Let me explain.

The Xojo database classes are very generic. To insert data into the recordset you either use an SQL Insert statement or use the DatabaseRecord class. The SQL statement, by itself if fraught with peril as it’s very easy to mistype the statement and miss it in testing. Even using PreparedStatements (which you should be using whenever possible) you can still screw it up. Using the DatabaseRecord class is more object oriented and without a doubt easier to use but it has one big problem: It doesn’t check datatypes. At design time it will happily let you try to put a date value into an integer field (depends on how you try, of course). It is not until runtime that you may get any sort error which leads to the next issue.

Database errors, at least in the global framework, do not generate exceptions. This means that unless you, the developer, check for the error, you may not get the results you expect. On an Insert statement, either using SQL or the DatabaseRecord, your data may simply never be inserted and you’ll never know it unless you’re checking the Error property on the database connection. The Error must be checked after EVERY SQL action whether that be SQL Select, Insert, or Delete. Even checking after a Prepare statement is wise to do so.

The good news (maybe) is that Xojo for iOS and the iOSSQLiteDatabase class will throw an exception if it experiences a database error. It’s good that you don’t need to check for the error manually, but now you need to put in exception handling around your database code and deal with exceptions accordingly. It’s not hard, but it’s also not trivial code either.

The IDE knows next to nothing about the database and certainly when you code it you have to query the database for Table and Field schema’s. To make it worse, the Xojo database framework has no idea about the concept of Views requiring you to query the database specifically to find and learn more about them. The IDE has no idea about the field datatypes either and the compiler can’t warn you about mismatched datatypes. These types of errors are only caught at runtime which is usually way too late in the process (hopefully not by the client either).

The database frameworks are not very object oriented friendly. If you have a simple Add/Edit dialog you need to know if the record is new, or not, since this changes how you code saving the data. New requires the DatabaseRecord object and an existing record can be updated via the Recordset object (both can use SQL statements but the statements themselves require different statements).

Xojo is easy to use but the ability to stick code in control events tends to make big database applications unwieldy and full of spaghetti code. Changing a field name in a commonly used table, or even worse changing the field datatype, is often at your own peril because you might have SQL statements referencing it in hundreds of places in the code. Forget it one place and you have an error in the waiting.

Finally, there’s the hooking your user interface up to your database code. Many people have Load/Save methods in every window/dialog/container that needs it. Use a SQL statement to get the data, then use the Recordset to load the user interface, and then use a Save method (that knows the difference between new and existing records) to put it back into the database. Again, the IDE compiler can’t help you if you make either a spelling mistake in the SQL statement or Field names so you won’t find these errors out until runtime (which is often too late).

There are options, to all of these problems. Creating your own data classes is a step above the standard Xojo code, in my opinion. You encapsulate a record into a Xojo class and implement your own Load and Save methods. This is a better object and forces some compiler warnings into your code. It also tends to put your database code all in one folder and/or NameSpace. You can use field name constants for field names, and force all db code into one class or module. Unfortunately, if you have hundreds of tables it’s also tedious to do all this.

There are other solutions out there, but ARGen takes some of the tediousness out of the work of creating a Xojo database application and does some other nifty things too like creating a basic User Interface for you.. ARGen is short for ActiveRecord Generator. ActiveRecord is a set of classes that map the database into equivalent Xojo namespaced classes.

Say you have a table named Employee. ARGen would create a class named ‘Employee’ in the ‘Data’ namespace and you would reference it in code as Data.Employee. Each field in the table is then mapped to a property in the class. The FirstName text field would be mapped to a string property named “FirstName”. This property is referenced as Data.Employee.FirstName and since the compiler knows this property is a string it will complain if you try and put an integer into it. Since there’s only one place you would ever define FirstName in your project it becomes really easy to change the name or change the datatype and then have the compiler catch any errors. It also means that AutoComplete in the code editor works meaning you’ll never mistype a table or field name again without the compiler catching it.

When an ActiveRecord project first starts up and connects to the database we call a Register method that calls out which tables/views are added into ActiveRecord. ActiveRecord scans the schema of the table and then attempts to match up every field with a corresponding property on the class. If a field is missing from your class it will generate an error that’s caught only while debugging (a “table x is missing field y” type of message).

Each ActiveRecord instance is a complete record. It has built-in Save and Delete methods. It also has events for Before and After Create, Before and After Update, to let you do things globally for each record. One example we use all the time are CreatedBy, CreatedDate fields in the Before Create event and ModifiedBy and ModifiedDate fields in the Before Update event. One place, ever, to put that data into the database rather than the potential thousands of places it might. There is also a convenient IsModified method to figure out if data has actually changed or not.

The Save method knows if it’s a new record or an existing record and does the right thing behind the scenes for you. Using a transaction, using a PreparedStatement. I think this one feature alone saves us hundreds of hours of coding because it’s a simple Save call. Nothing more be done. It really takes the worry out of it.

There are other coding features that we could get into but it all revolves around making creating database applications in Xojo fast and easy. ARGen creates a bunch of helper functions like IsDuplicate, List, and so on to help make your life easier. ARGen has a free mode which allows you to get the ActiveRecord classes and up to two tables at a time done.

For many years this is all ARGen did and we used it with great success. However, we found ourselves spending a lot of time on the next step – creating windows, dialogs, and containers and hooking up the database classes to the User Interface. Practically every table you run across has a List and Edit form. In version 2 we added the ability create a rudimentary User Interface which saves even more time. You only get this ability with the fully paid version.

When generating a Xojo project ARGen puts in a number of #pragma error statements where the developer needs to look at code and uncomment code and/or fix code. It’s hard to guess and frankly we don’t want your newly generated project to compile without you having to fix some code. Trust me – it’s better this way. There are simply too many variables and ways of doing things. Because of the #pragma error statements I like to bring over classes and UI over from the generated project as I need them rather than all at once. No need to fix hundreds of pieces of code until you’re ready to look at them.

ARGen and ActiveRecord isn’t perfect and it’s not the only solution around. ARGen lets the compiler do some work for you and eliminates some of the very common, but trivial, mistakes. It also lets you save a ton of time when it comes to standard database code and building user interfaces. It isn’t a panacea for development but ARGen can save you a lot of time and effort.

If you’d like to learn more about ARGen and what it can do for you, please download the free/demo version from the product page at http://www.bkeeney.com/allproducts/argen/. There are several videos on the ARGen menu that show more details.

Update:  I did a Xojo webinar a while back that talks about some of this in detail.  It’s a little dated but worth watching:  http://developer.xojo.com/webinar-simplying-db-access-with-bkeeney-activerecord

Existing Users Should Note:
The App.AppDataDirectory, App.AppIcon, and App.AppImageDirectory methods have been moved to PreferencesModule to make Shorts easier to install. Please be aware that you may need to update the PreferencesModule.AppIcon method with your existing App.AppIcon code.
The App.kAppName constant has also been moved into the PreferencesModule. The value now comes from the PreferencesModule.AppName method, which can automatically discern the app name, or you can have it return a string of your choosing. The later approach may be more desirable if you used a value in the kAppName constant that was not the actual value of your app’s file name when built.

For best results when updating, delete the three methods and constant from the App object. This will highlight any spots you may have referenced these methods (and will need to update them)

Updates are available through FileShare and you should get a notification email.

Is Xojo the Right Development Tool

Quite often prospective clients, and developers thinking of learning Xojo, ask my opinion of Xojo.  They are about to embark on a journey spending tens of thousands of dollars on a cross-platform tool and they want to know if Xojo is a right for them.  It’s a good question and I’ll share some of what I share with them in no particular order.

Xojo is pronounced “Zo Jo”.  I can’t tell you how many times I’ve heard it pronounced “Ex Oh Jay Oh” or something else.  They just don’t know and I think it spooks a lot of people as it doesn’t exactly roll off the tongue.  Xojo has been around under various names (REALbasic and Real Studio) for twenty years – all with the same company.  At that point it’s easy to name a dozen languages/development environments that were popular twenty years ago that either don’t exist today or been sold so many times that they’re now obscure tools.

This isn’t your fathers BASIC.  Xojo uses the BASIC syntax but this isn’t like the venerable Visual Basic or even older GWBasic or QBasic.  Xojo apps are NOT interpreted at runtime – they compile down into native code for each of the platforms.  The language itself is a modern object-oriented language that happens to use the BASIC syntax.  Xojo is updated three to four times a year and has undergone a lot of upgrades in the past two decades.  It first supported 68000 code, then PowerPC and Fat applications, Carbon, and now finally Cocoa on the Mac side.  They’ve added Windows, Linux, Raspberry Pi (Linux ARM), desktop and console application targets.  In the mobile space they’ve added iOS, and by the end of the year Android.  They’re also in the middle of the transition from 32-bit only applications to 64-bit applications.  For the most part things ‘just work’ and developers don’t experience too many issues (bugs happen but think about how many targets they’re supporting!).

Xojo applications are self-contained.  Take a compiled Xojo application and (with very few exceptions) literally copy the files to another computer and the application will just work.  Even Windows applications don’t need an official installer, however, it is recommended since most Windows users are comfortable and familiar with using them.  Most Mac applications are installed via drag-and-drop from a disk image but an installer can be used on the Mac as well.  This ease-of-installation is huge and it’s rare to have “DLL Hell” issue since all required libraries and resources are bundled together.  This does make the resulting output larger than some other development tools that depend on system libraries but I’ve rarely seen this an issue.

Xojo provides nearly everything you need in one tool (with some caveats).  The Xojo IDE has Code, Form, Menubar, Database, and Report editors (to name some of the big ones) in one tool so you never have to use another tool.  We’ve found the database editor to not be powerful enough so we prefer external database editors.  The built-in reporting tool also isn’t very powerful so we created our own reporting tool (Shorts) which has served us well in our consulting projects.  The nice thing is that all of the built-in tools work seamlessly with each other so the tools that are powerful enough for you ‘just work’ with few hassles.  The editors try really hard to protect your from hurting yourself while other tools are just a big text file that must be in an exact format.

The Xojo community is incredibly helpful.  The Xojo Forums are filled with some of the most helpful people I’ve ever met.  Some of the Xojo engineers respond to questions, but usually the community answers before they get to it.  Many other support forums are rude and condescending to newcomers to their language/tool.  The Xojo forum has even been known to answer questions about other tools.

Xojo is a cross-platform tool and because of this it has some compromises.  Controls are often the lowest- common denominator.  Grids especially aren’t as powerful as some are used to in the Windows world.  This is mainly because complex grids are not common in Linux and Mac environments.  Other controls have similar issues.  Things like automatic spell checking in TextArea’s are platform specific as on the Mac.  At times it is disappointing that there aren’t more control options for Xojo right out of the box (think date and calendar controls) but thankfully there is a third-party market for controls and libraries for Xojo that can often help.  Even though much is provided for you, it’s possible for a developer to use OS API’s using Declares that can significantly modify the appearance and functionality for some applications.

Xojo is a Rapid Application Development (RAD) environment.  Between the all-in-one IDE and the language creating applications in Xojo is fast.  This means that an initial investment can get your app developed faster and cheaper than many other languages.  Obviously some of this depends on the developers doing the work but it can make a huge difference.  We’ve always told clients that if they’re not happy with Xojo performance after the initial release they can use our code as the proof of concept to the developer in whatever language they choose.  There have only been a handful of clients that have ever switched languages after release and that’s usually been switching from desktop apps to web app.

The cost of Xojo isn’t very high compared to some tools.  For $699 per year per developer you can create web, console, and desktop apps for Mac, Windows, Linux, and Linux ARM plus iOS apps.  That’s all in the same environment and same language and with the exception of iOS applications (which requires a Mac) you can use Mac, Windows, or Linux to create everything.  Many developers use third party controls and libraries and even those are relatively inexpensive.  Plus, there are no royalty fees for your Xojo made applications.  All-in-All it can be a relatively inexpensive tool.

What considerations have I missed?

MBS Berlin Developers Conference Keynote

Geoff Perlman, CEO of Xojo Inc gave his keynote address at the Berlin Xojo Developers Conference today.  The conference is hosted by Monkeybread Software.  In his hour long talk, he discussed the future of Xojo and, in particular, what’s scheduled for the rest of 2017.

In the past two years, Xojo releases have fixed over 1,000 bugs.  They’ve also add 200 major features.  This includes a new Language Reference, HiDPI support for Mac, Windows, and Web, Raspberry Pi support, 64-bit builds, and iOS additions.  Uploading in Xojo Cloud is now 400% faster and new data centers were added in New York, San Francisco, London, Amsterdam, Bangalore and Singapore.

Geoff spent some time talking about things coming up in 2017.  In Release 2, due out in July, 64-bit builds will no longer be beta status.  64-Bit debugging for Windows will be a reality.  Geoff said that it was almost available for R1 but the version of LLVM  for Windows they needed was too new.  XojoScript will be 64-bit as well.  The split and join string operations have been reconfigured to make them comparable in speed to the 32-bit versions.

For Windows, 64-bit builds will have app icons and version information.  Neither of these are available in R1 and earlier 64-bit builds for Windows.  Linux will now use GTK3 which will allow a 64-bit HTMLViewer.  A stretch goal might be HiDPI support and Geoff said that this might be later.

Later in the 2017, after R2, here are the goals:  64-bit builds will be the default in the IDE (32-bit will still be available).  The IDE itself will be 64-bit.

Also scheduled for 2017 is a new plugin format.  This new format will require Xojo Pro for creation.  It will still support libraries written in C/C++.  You can add images, sounds and other resources.

One of the more interesting things about the new plugin format is that it’s project-local.  Currently all plugins are global which means you cannot have multiple versions of the same plugin installed.  This new plugin format is project based, so it’s easier to handle different versions for different projects.  The new Xojo plugins are compiled into an intermediate LLVM format so there’s no need to ship classes with encrypted source code.

Even though the existing plugin format will be around for many years the new format is definitely the wave of the the future.  This will be the ONLY format supported for mobile.

The IDE is being redesigned.  Geoff admitted that the Navigator isn’t great for large projects and in some cases works against you.  The current Navigator is a custom canvas control and later this year it will be replaced with a standard ListBox.  This will make the next step easier and it will make tabs work as a hybrid between the old Real Studio and the newer Xojo IDE.  Geoff showed some screen mockups and design document so it felt like they know exactly what they want, they just need the time to implement it.

Next up was Interops.  Currently working with Declares is challenging.  Differing versions of OS SDK versions are hard to deal with.  There is also no type conversion.  Interops promises to make all these issues go away and use nothing but Xojo data types.

Geoff showed an example of an SDK call in Swift for iOS.  Then he showed the ugly Xojo declares for it, which didn’t look like Xojo code at all, and then showed the Interops version.  The Interops version looked nearly identical to the Swift versions.  This is the technology used to develop Android.  Interops will be developed first for mobile and then MacOS.

Finally, Geoff talked about Android.  He said a beta of Android will be out by the end of 2017.  It will be using Interops to make development easier and will create native code and controls.  Apps will be compiled into machine code which should give Xojo Android apps comparable performance as Google’s own native apps.   Support will be for KitKat version 4.4 or later which is roughly 80% of the installed user base.

Geoff wrapped up his talked with a brief look back at the competitors to Xojo when the company was first started.  Apples MPW, Microsoft Visual Basic, Delphi, MetroWerks CodeWarrior, Sun’s Java, Symantec Think C were all the rage.  Some of those tools no longer exist.  Some of those tools have been sold multiple times with different strategies.  For over 20 years Xojo has stayed with the same company and continues to evolve and change to meet the needs of users.
