Visual Studio Code – getting started – some links

Posted by jpluimers on 2017/10/05

It might sound like I’m late in the game, but remember that blog posts are usually scheduled like a year in advance.

So I found out a long time ago (I think it’s Matthijs ter Woord who attended me) about Visual Studio Code.

At the start [WayBack] it was more limited (from memory something like C#, TypeScript, Java Script languages and frameworks Node.js and ASP.NET 5) than my other development environments but now it’s much richer.

It’s based on the Electron framework which I kew from the Atom.io editor and Koush‘s framework Electron Chrome that wraps Chrome Apps in Electron so he ensured Vysor would live after Google will kill Chrome Apps.

Oh it’s free and runs multi-platform which I like a lot (and was one of the reasons to start using Atom.io): Mac OS X, Windows and Linux are supported.

So here are a few links to get started:

I got reminded a while back** that it is now supported by OmniPascal [WayBack] which I like because of my Turbo Pascal -> VAX/VMS -> csh -> Delphi -> AS/400 -> .NET background.

Like Visual Studio Code is updated often, the Omni Pascal blog [WayBack] shows regular updates and I like it a lot better than the Lazarus IDE (I’m not a visual RAD person: I’m a RAD code person) especially the refactorings.

So start playing with it. I will post more about my Visual Studio Code experience in due time.

reStructuredText Interpreted Text Roles

Posted by jpluimers on 2017/10/04

There is so much great stuff in reStructuredText, take for instance [WayBack] reStructuredText Interpreted Text Roles where basically can create your own role (for instance :csharp: or :delphi: roles based on :code: for syntax-highlighted code blocks given the right syntax highlighters).

I got there via this great piece by[WayBack] Chris who answered [WayBack] Inline code highlighting in reStructuredText – Stack Overflow:

Having looked into this some more I stumbled upon the document reStructuredText Interpreted Text Roles. From this document:

Interpreted text uses backquotes (`) around the text. An explicit role marker may optionally appear before or after the text, delimited with colons. For example:

This is `interpreted text` using the default role.

This is :title:`interpreted text` using an explicit role.

It seems that there is a code role, so you can simply type

:code:`a = b + c`

to render an inline code block. To get syntax highlighting you can define a custom role. For example

.. role:: bash(code)
   :language: bash

which you can then use like so:

Here is some awesome bash code :bash:`a = b + c`.

Note, the document I link to makes no mention of the version of docutils to which it refers. The code role is not available in docutils 0.8.1 (which is the only version I have to test against).

A bit of Kylix history…

Posted by jpluimers on 2017/10/03

Chris Rolliston: +Larry Hengen The Kylix IDE was a fork of the Delphi IDE and used WineLib. It was the applications you built with the Kylix IDE that were QT based.

Via [WayBack] I don’t mean to Whine but, if WINE is mature enough, why doesn’t EMBT officially test and support WINE for development on Mac OS/X and Linux for… – Larry Hengen – Google+

There is a bit of C++BuilderX history as well (which was based on JBuilder).

When your Windows 8.1 mouse cursor is invisible in the screen center on VMware Fusion

Posted by jpluimers on 2017/10/02

Remove the

Remove the “VMware Pointing Device” using “devmgmt.msc”

Somehow I have it happen every now and then on Windows (usually 8.1 x64) VMs running inside a VMware (usually Fusion) that the mouse cursor is stuck.

VMware Tools were already at the latest version and a plain reboot didn’t help.

It doesn’t matter if I was running full screen or Windows and altering these mouse settings did not change the behaviour:

  • Enable pointer shadow
  • Display pointer trails (long or short: does not matter)

I did enable Show location of pointer when I press the CTRL key which then indicated the mouse pointer was static at the screen center.

The only thing to get the mouse respond to mouse movement were these steps:

  1. Start Device Manager using devmgmt.msc
  2. Switch to the Devices by Connection view from the View menu
  3. Open these sub-trees:
    1. Your machine in this case my machine W81ENTX64VS2015
    2. ACPI x64-based PC
    3. Microsoft ACPI-Compliant System
    4. PCI Bus
    5. Intel 82371AB/EB PCI to ISA bridge (ISA mode)
  4. Now delete the VMware Pointing Device
  5. Reboot after Device Manager ask you to do so

After that my mouse cursor works fine.

Just in case you bump into a similar thing, but the above steps don’t help, here are some links with different steps that might work in your situation:

Raspberry Pi brexit – changing your locale away from GB when you’ve a different keyboard

Posted by jpluimers on 2017/10/02

A while ago I wrote about -bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) on fresh Raspbian on Raspberry

I thought my locale issues were solved and they sort of were. Until I had to logon locally and managed to get one or more of these characters in my password:

  • ~ (tilde)
  • @ (at)
  • # (hash)
  • \ (backslash)
  • | (pipe)
  • " (double-quote)

Then logon would fail locally but work via ssh. Go figure!

Lot’s of people outside the UK using their Raspberry Pi with keyboard and monitor will now say: you’ve the default GB keyboard layout and your keyboard is not GB.

Bingo!

This is how US keys look when using a GB keyboard layout:
