UX improvements: `enterkeyhint` to define action label for the keyboard of mobile devices

Usability

The enterkeyhint is a html attribute described in the HTML standard, which can be used to improve the context of action buttons of keyboards on mobile device.

The enterkeyhint content attribute is an enumerated attribute that specifies what action label (or icon) to present for the enter key on virtual keyboards. This allows authors to customize the presentation of the enter key in order to make it more helpful for users.

It allows the following fixed values: enter, done, go, next, previous, search and send. Let’s have a look at those values and the resulting keyboard style on iOS:

<input>

The default behavior without any value.

<input enterkeyhint=”enter”>

The user agent should present a cue for the operation ‘enter’, typically inserting a new line.

<input enterkeyhint=”done”>

The user agent should present a cue for the operation ‘done’, typically meaning there is nothing more to input and the input method editor (IME) will be closed.

<input enterkeyhint=”go”>

The user agent should present a cue for the operation ‘go’, typically meaning to take the user to the target of the text they typed.

<input enterkeyhint=”next”>

The user agent should present a cue for the operation ‘next’, typically taking the user to the next field that will accept text.

<input enterkeyhint=”previous”>

The user agent should present a cue for the operation ‘previous’, typically taking the user to the previous field that will accept text.

<input enterkeyhint=”search”>

The user agent should present a cue for the operation ‘search’, typically taking the user to the results of searching for the text they have typed.

<input enterkeyhint=”send”>

The user agent should present a cue for the operation ‘send’, typically delivering the text to its target.

Android Studio: when shortcuts do not work on macOS

Compared to other IntelliJ® based software, some shortcuts in Android Studio did not work for me. For example cmd + shift + F, which should open the global search did not work.

The reason for this is the keymap setting that was set to IntelliJ IDEA Classic. Setting the keymap to macOS (as shown in the figure below) solved the issue.

PNG – deactivate interlace to avoid ‘libpng warning: Interlace handling should be turned on when using png_read_image’

I stumbled appon a warning message that was thrown by PHP when handling images with GD lib (e.g. imagecreatefrompng()). The message shown was:

libpng warning: Interlace handling should be turned on when using png_read_image

This message even exists, when deactivating ‘interlace’ with the help of:

imageinterlace($img, false);

The point is that this message is not caused by any wrong php code, it is caused by the processed images itself. The only solution is to deactivate interlace for the processed image(s). This is possible with ImageMagick. To deactivate interlace on all images of a folder, the following command can be used:

magick mogrify -interlace none *.png

I used ImageMagick on macos and installed it with with HomeBrew:

brew install imagemagick

Xcode fails to generate source files from intent definition files when using the Legacy Build System

The workaround for this problem is the following: First, add a Run Script phase before the Compile Sources phase of your target:

xcrun intentbuilderc generate -input ${SRCROOT}/PATH/TO/Intents.intentdefinition -output ${SRCROOT}/Intents -classPrefix "" -language Swift -swiftVersion 5.0

Then, add all of the generated files from the output path specified in the command above to all required targets in your project.

Change default reading font in Outlook from Times New Roman to Calibri (or any other)

I use Outlook 2016 and some emails are shown in Times New Roman, even if the default font was set to Calibri. This is the case, when HTML mails do not have any CSS style. In this case, Outlook uses the default fall back font Times New Roman. It took me some time to realise that there is no setting for this in Outlook.

But: the related setting can be found in Word 2016 (yes, Word!).

To change the setting, open Word and go to:

File > Options > Advanced > General section > Web Options… > Fonts tab > Proportional font …

There you can change the setting with Times New Roman font to any other font. After the change you have to restart Outlook. Each unformated HTML mail should now be displayed in the selected font.

Background tasks in iOS

As already discussed in Background task in iOS action extension, it sometimes becomes necessary to perform time consuming tasks in the background. This is really important, if such a task would block the user interaction. Especially for action and share extensions, this might lead to some waiting time before a task completes and the extension disappears. After several attempts to realise a working solution, the following code help to extends an App’s background execution time.

This code was described in the article Extending Your App’s Background Execution Time.

Extending the background execution time in an app

func performTask()
{
   // Perform the task on a background queue.
   DispatchQueue.global().async {
      // Request the task assertion and save the ID.
      self.backgroundTaskID = UIApplication.shared.
                 beginBackgroundTask (withName: "Perform Long Task") {
         // End the task if time expires.
         UIApplication.shared.endBackgroundTask(self.backgroundTaskID!)
         self.backgroundTaskID = UIBackgroundTaskInvalid
      }
            
      // Run task synchronously.
      self.performLongTask()
            
      // End the task assertion.
      UIApplication.shared.endBackgroundTask(self.backgroundTaskID!)
      self.backgroundTaskID = UIBackgroundTaskInvalid
   }
}

Extending the background execution time in an extension

func performTask()
{
   // Perform the task in background.
   let processinfo = ProcessInfo()
   processinfo.performExpiringActivity(withReason: "Long task") { (expired) in
      if (!expired) {
         // Run task synchronously.
         self.performLongTask()
      }
      else {
         // Cancel task.
         self.cancelLongTask()
      }
   }
}

As mentioned in the documentation, the ProcessInfo code block is called a second time if the system need to suspend the process:

If your block is still executing and the system need to suspend the process, the system executes your block a second time with the expired parameter set to true. Your block must be prepared to handle this case. When the expired parameter is true, stop any in-progress tasks as quickly as possible.

Source: https://developer.apple.com/documentation/foundation/processinfo/1617030-performexpiringactivity

Important: it’s important that the tasks are executed synchronously. When the end of the block is reached, the thread will terminate and end the execution of your task. If your tasks are asynchron, you can use a loop like shown below to wait inside the background thread until the asynchron task is finished:

// Keep background thread alive until asynchron task ends.
repeat {
    sleep(1)
} while(taskIsRunning)

Note To Self: how to instantly create tasks in Trello

If you are using the mail import feature of Trello, you can speed up the notes with Note To Self Mail. The app creates notes in Trello in seconds.

Setup Note To Self Mail for Trello

1. Get your Trello email address

Get your Trello email address by open up one of your boards in Trello and go to “Email-to-board Settings” ind the settings section of the sidebar. Emails sent to this address will appear as a task in this board. The subject of the email will become the title and the body will become the description.

2. Add your Trello email address to Note To Self Mail

Add this email address to Note To Self Mail. You can also set the label to “Trello” or any other descriptive name.

Note To Self Mail > Settings > Add email …

3. Adjust the subject

Trello uses the subject as a main source of a new note. Set the subject to “Use first line of note”. This ensures, that the first line is used as subject and all the other text lines are moved to the description of the task.

Note To Self Mail > Settings > Add email … > Subject

Usage

There are some shortcuts or special chars that can be used in the subject of the mail. All available features are described in Trello’s documentation: Formatting Tips (opens in a new tab)”>Creating cards by email > Formatting Tips.

Now, you can send any note to Trello. With the following text …

… a new task will be created in Trello …

You might notice, that the task was placed in the correct list (as set in Trello) and was tagged with “home”. All the other contents of the input (line 2 up to the end) are moved to the task description. That’s it!
