-# calliope target for PXT
+# Calliope target for Microsoft MakeCode
+
+This target is hosted at https://makecode.calliope.cc.
+
+## Hosted editor and build
+
+Jenkins build: https://ci2.dot.net/job/Private/job/pxt_project_teal/job/master/
 
 
+### BUILD COMMENTS
 
-pxt-calliope is a [Microsoft Programming Experience Toolkit (PXT)](https://github.com/Microsoft/pxt) target that allows you to program a [Calliope mini](https://calliope.cc/en). 
+- build libs/core/dal.d.ts new requires some meddling, as the `#define` parser does not parse `#ifdef` and thus
+has some conflicts with double defines constants
 
+![](http://calliope.cc/content/1-ueber-mini/mini_board.png)
 
-* [Try it live](https://makecode.calliope.cc/)
+## Local server
 
-## Issue tracking
+The local server allows to run the editor and the documentation from your computer.
 
-Please add an issue if you discover an (unreported) bug.
+### Setup
 
-## Developing new extensions
+The following commands are a 1-time setup after synching the repo on your machine.
 
-Authoring and testing of new extensions can be done directly from the web editor. See [our documentation](https://makecode.com/blog/github-packages) on how to get started. If you want to run the editor locally, keep reading.
-
-## Local server setup
-
-The local server lets you to run the editor and serve the documentation from your own computer. It is meant for a single developer used and not designed to serve the editor to a large amount of users.
-
-1. Install [Node.js](https://nodejs.org/) 8.9.4 or higher.
-2. Clone this repository.
+* See requirements for [pxt](https://github.com/Microsoft/pxt)

 ```
 
-Go to the **Running** section.
-
-### Developer Setup
-
-This is the typical setup used by the MakeCode team to work on the microbit.
-
-1. Install [Node.js](https://nodejs.org/) 8.9.4 or higher.
-2. Install [Docker](https://www.docker.com/get-started) if you plan to build ``.cpp`` files.
-3. Clone the pxt repository.
-```
-git clone https://github.com/microsoft/pxt
-cd pxt
-```
-4. Install the dependencies of pxt and build it
-```
-npm install
-npm run build
-cd ..
-```
-5. Clone the pxt-common-packages repository
-```
-git clone https://github.com/microsoft/pxt-common-packages
-cd pxt-common-packages
-npm install
-cd ..
-```
-6. Clone this repository.
-```
-git clone https://github.com/microsoft/pxt-calliope
-cd pxt-calliope
-```
-7. Install the PXT command line (add `sudo` for Mac/Linux shells).
-```
-npm install -g pxt
-```
-8. Install the pxt-calliope dependencies.
-```
-npm install
-```
-8. Link pxt-calliope back to base pxt repo (add `sudo` for Mac/Linux shells). 
-This step is only required if you intend to make changes to pxt and/or 
-pxt-common-packages repos. If all you want is serve a local Makecode, you can skip
-this step.
-```
-pxt link ../pxt
-pxt link ../pxt-common-packages
-```
-Note the above command assumes the folder structure of   
-```
-       makecode
-          |
-  ----------------------------------
-  |       |                        |

 ### Running
 
-Run this command from inside pxt-calliope to open a local web server
+Run this command to open a local web server (add ``sudo`` for Mac/Linux shells).
 ```
 pxt serve
 ```
 If the local server opens in the wrong browser, make sure to copy the URL containing the local token. 
 Otherwise, the editor will not be able to load the projects.
 
-If you need to modify the `.cpp` files (and have installed yotta), enable yotta compilation using the `--localbuild` flag:
+If you need modify the `.cpp` files, turn on yotta compilation with the ``-yt`` flag (add ``sudo`` for Mac/Linux shells). On Windows, you must be running
+from the ``Run Yotta`` command prompt.
 ```
-pxt serve --local
+pxt serve -yt
 ```
 
-If you want to speed up the build, you can use the ``rebundle`` option, which skips building and simply refreshes the target information
+## Updates
+
+To update your PXT version and make sure you're running the latest tools, run (add ``sudo`` for Mac/Linux shells)
 ```
-pxt serve --rebundle
+pxt update
 ```
 
-### Cleaning
+More instructions at https://github.com/Microsoft/pxt#running-a-target-from-localhost 
 
-Sometimes, your built folder might be in a bad state, clean it and try again.
-```
-pxt clean
-```
+## Testing
 
-### Updates
+The build automatically runs the following:
 
-Make sure to pull changes from all repos regularly. More instructions are at https://github.com/Microsoft/pxt#running-a-target-from-localhost
+* make sure the built-in packages compile
+* `pxt run` in `libs/lang-test*` - this will run the test in command line runner; 
+  there is a number of asserts in both of these
+* `pxt testdir` in `tests` - this makes sure all the files compile and generates .hex files
 
-## Update playlists in markdown
+To test something on the device:
 
-Get a Google API key and store it in the ``GOOGLE_API_KEY`` environment variables (turn on data from the app).
+* do a `pxt deploy` in `libs/lang-test*` - they should show `1` or `2` on the screen (and not unhappy face)
+* run `pxt testdir` in `tests` and deploy some of the hex files from `tests/built`
 
-```
-pxt downloadplaylists

-
-## Repos 
-
-The pxt-calliope target depends on several other repos. The main ones are:
-- https://github.com/Microsoft/pxt, the PXT framework
-- https://github.com/Microsoft/pxt-common-packages, common APIs accross various MakeCode editors
-- https://github.com/lancaster-university/microbit, basic wrapper around the DAL
-- https://github.com/lancaster-university/microbit-dal
-
-## History
-
-See the [MakeCode blog](https://makecode.com/blog).
+The `lang-test0` source comes from the `pxt-core` package. It's also tested with `pxt run` there.

-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must

-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

 # About
 
-## @description A Blocks / Javascript code editor for the Calliope mini, a pocket-size computer with 5x5 display, sensors and Bluetooth.
-
-The [Calliope mini](https://calliope.cc) is a [pocket-size computer]([/device](https://calliope.cc/en/calliope-mini/tech-facts)) with a 5x5 display of 25 LEDs, Bluetooth and sensors that can be programmed by anyone.
-
-The Calliope mini provides an easy and fun introduction to programming and making ??? switch on, program it to do something fun ??? wear it, customize it.
-Just like Arduino, the Calliope mini can additionally be connected to and interact with sensors, displays, and other devices. 
-
-* [Read the docs](/docs)
-
-## [Hardware: The Device](/device)
-
-The Calliope mini is packaged with sensors, radio and other goodies. Learn about the [hardware components]([/device](https://calliope.cc/en/calliope-mini/tech-facts)) of the Calliope mini to make the most of it!
-
-## ~ hint
-
-**Looking to buy a Calliope mini?** See the [list of resellers](https://calliope.cc/en/shops).
-
-## ~
-
-## Programming: [Blocks](/blocks) or [JavaScript](/javascript)
-
-You can program the Calliope mini using [Blocks](/blocks) or [JavaScript](/javascript) in your web browser via the [Calliope mini APIs](/reference):
-
-```block
-input.onButtonEvent(Button.A, input.buttonEventValue(ButtonEvent.Down), () => {
-    basic.showString("Hi!");
-})
-```
-```typescript
-input.onButtonEvent(Button.A, input.buttonEventValue(ButtonEvent.Down), () => {
-    basic.showString("Hi!");
-})
-```
-
-The editor work in [most modern browsers](/browsers), work [offline](/offline) once loaded and do not require any installation. 
-
-## [Compile and Flash: Your Program!](/device/usb)
-
-When you have your code ready, you connect your Calliope mini to a computer via a USB cable, so it appears as a mounted drive (named MINI). If you are using the Calliope mini REV2 you also see another drive (FLASH) that handels up to 25 additional programs.  
-
-Compilation to ARM thumb machine code from [Blocks](/blocks) or [JavaScript](/javascript) happens in the browser. You save the ARM binary 
-program to a file, which you then copy to the micro:bit drive, which flashes the micro:bit device with the new program.
-
-## Simulator: Test Your Code
-
-You can run your code using the micro:bit simulator, all within the confines of a web browser. 
-The simulator has support for the LED screen, buttons, as well as compass, accelerometer, and digital I/O pins.
-
-```sim
-basic.forever(() => {
-  basic.showString("Hi!");
-})
-input.onButtonEvent(Button.A, input.buttonEventValue(ButtonEvent.Down), () => {
-    led.stopAnimation();
-    basic.showLeds(`
-. . . . .
-. # . # .
-. . . . .
-# . . . #
-. # # # .`);
-});
-input.onButtonEvent(Button.B, input.buttonEventValue(ButtonEvent.Down), () => {
-    led.stopAnimation();
-    basic.showLeds(`
-. # . # .
-# . # . #
-# . . . #
-. # . # .
-. . # . .`);
-});
-```
-
-## Learn!
-
-We have tons of [projects](/projects), [examples](/examples) and [courses](/courses) to get your started!
-
-## C++ Runtime
-
-The [C++ micro:bit runtime](http://lancaster-university.github.io/microbit-docs/), created at [Lancaster University](http://www.lancaster.ac.uk/), provides access to the hardware functions of the micro:bit, 
-as well as a set of helper functions (such as displaying a number/image/string on the LED screen). 
-
-The [micro:bit library](/reference) mirrors the functions of the C++ library. 
-When code is compiled to ARM machine code, the calls to JavaScript micro:bit functions are replaced with calls to the corresponding C++ functions.
-
-## [Command Line Tools](/cli)
-
-Looking to use @homeurl@ in your favorite editor? Install the [command line tools](/cli) and get rolling!
-
-## [Extensions](/extensions)
-
-Create, edit and distribute your own blocks and JavaScript using [extensions](/extensions). Extensions are hosted on GitHub and may be written using C++, JavaScript and/or ARM thumb.
-
-## [Open Source](/open-source)
-
-The code for the Calliope mini is [open source](/open-source) on GitHub. Contributors are welcome!

-## Example: ``AND`` operator
+A Boolean has one of two possible values: `true`; `false`.  Boolean (logical) operators (*and*, *or*, *not*) take Boolean inputs and yields a Boolean value. Comparison operators on other types ([numbers](/reference/types/number), [strings](/reference/types/string) yields a Boolean value.
+
+The following blocks represent the true and false Boolean values, which can be plugged in anywhere a Boolean value is expected:
+
+```blocks
+true;
+false;
+```
+
+The next three blocks represent the three Boolean (logic) operators:
+
+```blocks
+true && false;
+true || false;
+!true;
+```
+
+The next six blocks represent comparison operators that yield a Boolean value. Most comparisons you will do involve [numbers](/reference/types/number):
+
+```blocks
+42 == 0;
+42 != 0;
+42 < 0;
+42 > 0;
+42 <= 0;
+42 >= 0;
+```
+
+Boolean values and operators are often used with an [if](/blocks/logic/if) or [while](/blocks/loops/while) statement to determine which code will execute next. For example:
+
+### Functions that return a Boolean
+
+Some functions return a Boolean value, which you can store in a Boolean variable. For example, the following code gets the on/off state of `point (1, 2)` and stores this in the Boolean variable named `on`. Then the code clears the screen if `on` is `true`:
+
+### Boolean operators
+
+Boolean operators take Boolean inputs and evaluate to a Boolean output:
+
+### Conjunction: `A and B`
+
+`A and B` evaluates to `true` if-and-only-if both A and B are true:
+
+```blocks
+false && false == false;
+false && true == false;
+true && false == false;
+true && true == true;
+```
+
+### Disjunction: `A or B`
+
+`A or B` evaluates to `true` if-and-only-if either A is true or B is true:
+
+```blocks
+false || false == false;
+false || true == true;
+true || false == true;
+true || true == true;
+```
+
+### Negation: `not A`
+
+`not A` evaluates to the opposite (negation) of A:
+
+```blocks
+!false == true;
+!true == false;
+```

-# ERSTE SCHRITTE: The 5X5 LED MATRIX
-
-## Introduction @unplugged
-
-Amongst other things, the Calliope mini comes with 25 red LEDs that can be turned on and off individually. If, for example, you wanted to display your name, you could program individual LEDs to light up in sequence so as to display the letters of your name one after the other. As this would be rather complex, you can also enter the character string into a text field and the Calliope Mini will light up the necessary LEDs in the correct order for you.
-
-## Step 1 @fullscreen
-
-
-### DISPLAYING A CHARACTER STRING
-To show your chosen sting of characters on the LED matrix, select the show string block from the Basic menu. Next, drag and attach this block to the Start block in the main screen. The text contained within the inverted commas will now be displayed on the Calliope mini when the program is started.
-
-```blocks
-basic.showString("hi!")
-```
-
-## Step 2 @fullscreen
-
-### DISPLAYING NUMBERS
-If you’d prefer to show a number instead of text, replace the text block in the main screen with the show number block from the Basic menu.
-
-```blocks
-basic.showNumber(0)
-```
-
-## Step 3 @fullscreen
-
-### DISPLAYING IMAGES
-To display a heart, a smiley or even a duck on your Calliope mini, Choose the show iconn block from the Basic menu and select any number of different images by simply clicking on the picture in the block.
-
-```blocks
-basic.showIcon(IconNames.Heart)
-```
-
-## Step 4 @fullscreen
-
-You can also create your very own images:
-Just select this block from the Basic menu and click in the boxes to create your very own image.
-
-```blocks
-basic.showLeds(`
-    . . . . .
-    . . . . .
-    . . . . .
-    . . . . .
-    . . . . .
-    `)
-```
-
-## Step 4 @fullscreen
-
-Wenn du keine Pause zwischen 2 Bildern festlegst, zeigt der Calliope mini das erste Bild null Sekunden lang, also gar nicht. Den Warte ms Block findest du im Menü Kontrolle.
-
-```blocks
-basic.showIcon(IconNames.Heart)
-basic.pause(100)
-basic.showIcon(IconNames.Yes)

-## Introduction @unplugged
-
-Options within a program can be made dependent not only on inputs, but also on other conditions. For example, you can create an oracle that randomly shows a sad or a happy smiley:
-
-## Step 1 @fullscreen
-
-### If – then do relationship
-The actions below the "then“ are only executed if the condition before is fulfilled.
-In this case, the heart will not be visible on the LED grid, as the decision variable is not equal to 1. You can find the if…then block in the Logic section.
-
-## Step 2 @fullscreen
-
-### And on we go
-After the if…then block the program continues in any case, no matter whether the condition was fulfilled before or not.
-
-## Step 3 @fullscreen
-
-### If – then – else
-If you expand the if…then block, the first if condition is checked first, if it is not fulfilled the second if condition is checked. Only those actions are triggered for which the associated condition is fulfilled.
-
-Click on the + on the bottom of the block to unfold the if…then block. The probability to display either a happy or a sad smiley on the LED grid is 50/50.

-# FIRST STEPS: INPUTS
-
-## Introduction @unplugged
-
-So far all the programmed text, numbers and images have been displayed on the LED matrix immediately after being loaded onto the Calliope mini. However, if you would prefer to have an event take place after a specific input, you need to use the one of the main blocks from the Input section. In this case we are using the "on button A pressed“ block. By using this block, the Calliope mini will wait until your chosen condition is met before anything is displaying.
-
-## Step 1 @fullscreen
-
-### Buttons
-The Calliope mini has two input buttons: Button A (in red) and Button B (in blue). When one of the buttons is pressed, the circuit is completed.
-By using the "on button A pressed“ block from Input, you can display your output as soon as button A has been pressed.
-
-## Step 2 @fullscreen
-
-### Shake
-You can request the position and movement of the Calliope mini and run an action once a change of the values has been detected.
-Use the "on shake“ block from the Input section. Add an "show string Hi!" block from the Basic section and change the content of the string.Your text will be displayed when you shake the Calliope mini. The gesture can be changed by using the dropdown menu to choose the condition.
-
-## Step 3 @fullscreen
-
-### Pins
-The Calliope mini has five rounded corners: -, +, 0 , 1, 2, and 3. If you place one finger on the – corner and another finger on one of the numbered corners, a small electrical current will flow through your body and back to the Calliope mini, thus closing the electrical circuit.
-
-Use the „on pin Pin0 pressed" block from Input. Use the "show string Hi!" block from the basic section.
-Your text will be displayed when pin – and pin 0 are both pressed at the same time.
-
-## Step 4 @fullscreen
-
-### Various input
-You can program the Calliope mini to respond to more than one input. There are two possible ways of doing this:
-You can use indiviual events separated from each other with different actions to run after that condition is met.
-Nevertheless, you can also use an "if" or "while" condition (from the Logic and Loops sections) and wait for your inputs to be met.

-# FIRST STEPS: LOOPS
-
-## Introduction @unplugged
-
-As you may have noticed in previous exercises, your program was executed only once by Calliope mini. To change this, you can use loops. Use an infinite loop so that the text runs over the LED grid of your Calliope mini infinitely often.  
-
-## Step 1 @fullscreen
-
-### Infinite loop
-The simplest way is to use a foverever block, from the basic section.
-Everything inside will be repeated forever.
-
-## Step 2 @fullscreen
-
-Of course, you can also specify how often something should be repeated:
-
-### Repeat block
-Use the „on start“ block or any other block that usually initiates a one time cycle. Take the "Repeat 4 times" block from the Loops section and enter the desired number in the number field. Whatever task is within this block will be executed for the number of times you entered within the “Repeat …“ number.

-## Introduction @unplugged
-
-Calliope mini offers you the possibility to use different mathematical operations. You can calculate numbers, create random numbers and save your results in variables.
-
-## Step 1 @fullscreen
-
-### Calculation of numbers
-The Calliope mini is able to perform the 4 basic arithmetic operations addition, subtraction, multiplication and division out of the box:
-
-You can find the required block in the menu Math. From the block's drop-down list you can choose between the four basic arithmetic operations and the exponentiation. To see the result of your calculation, you have to put the block inside a „show number" block from the Basic section. The Calliope mini displays the result of your calculation on the LED grid.
-
-## Step 2 @fullscreen
-
-### Random numbers
-You can have Calliope mini create a random number: You can find the corresponding block in the menu Math ("pick random 0 to 10"). By changing the two numbers within the block, you determine how small or how large the random number is allowed to become.

-There is a Radio module built into the Calliope Mini. This allows for several Calliope mini to communicate with each other and transmit information. To try this out yourself, you will need at least two Calliope mini.
-
-
-## Step 1 @fullscreen
-
-### Allocating a channel
-Firstly you must decide on a channel to use. Only those Calliope mini that are using the same channel will be able to exchange messages with each other. A Calliope mini will not be able to transmit or receive over several channels at the same time. To be able to send information, you must open the radio block and use the radio set group block.
-Please ensure that the channel number you select is between 0 and 255.
-
-## Step 2 @fullscreen
