[ANN] Orientation

by Julien

Hello, I developed a small framework to model orientation (north, east, south, west). It defines some common operations that can be done on such objects (turning, getting the opposite orientation, moving on n steps on a discrete grid from a given position following certain orientation, etcâ¦). Also, it supporte composed orientations (e.g. north-east). More details on GitHub [1]. To install it: Metacello new baseline: 'Orientation'; repository: 'github://juliendelplanque/Orientation/repository'; load This is not a lot but it is tested and I think it does its job well. So if you need to model orientation, consider to use it. :-) If any ideas of what I could add to this API, Iâm interested.

[ANN] Python3Generator and MatplotLibBridge

by Julien

Hello, My new year main resolution: stop keeping my side-projects for me. Itâs been like 1 year that I created these two projects, one coming from a refactoring of the other. Now it is time to take time to announce them. I initially come from Python world and during my bachelor & master, I really liked to use matplotlib to plot data using Python. So I wanted to be able to use this Python module from Pharo. I did it by generating Python 3 code from Pharo and making Python 3 executing it. So, first I implemented everything in MatplotLibBridge package and then I split it in two package in order to be able to eventually create bridges to other Python 3 modules. So, Python3Generator [1] is made for generating programatically Python 3 code from Pharo. Basically, it allows you to easily build a Python 3 AST, to serialize it in Python 3 source code and eventually to execute it. For now you can transfer data from Pharo to Python (e.g. providing arguments to functions that are Pharoâs objects) but you can not retrieve data stored in Python variable from Pharo (but it should be possible, just I donât need to do that for my bridge to matplotlib). Some examples are provided on the githubâs README. MatplotLibBridge [2] is made for creating plots using matplotlib [3] from Pharo. There is a bunch of examples of what you can do on the README. The two features from matplotlib I like the most are: 1. You can generate your plot in a lot of file formats (png, pdf, svg, ps, etcâ¦) 2. It allows to embed LaTeX mathematical formulae everywhere in the plot (which can be really cool). All the possible plots in matplotlib are not available in Pharoâs side because I build parts of the bridge when I need them but it is not hard to do. I someone is interested in a plot type not available yet, please tell me. So, it is announced, if someone want to do something with those, please do it! Happy new year.

They recommande to have two colors for an application: - A primary color - An accent color The primary color is the main color of the application and the accent color is to make some highlights (links, important buttons...) For each color they defined scales. Each color have a code (50, 100, 200, 300, 400, 500, 600, 700, 800, 900). The base code is 500. If you need something "less important", with less contrast, you takes a lower code. For more contrast, you takes a higher code. See here: https://www.materialui.co/colors Also they have recommendation for text color. Dependently of the background color they define if the text should be white or black. (This is defined by the luminescence of the color in Pharo). Also, they define different text color if you have a primary text or a secondary text.

More named colors

by Stephane Ducasse

Hi Since for some experiences in moose we needed more named colors I started to gather together some old extensions and I cleaned the implementation. Now we have emacs colors and XKCD i.e around 1600 named colors. Gofer new smalltalkhubUser: 'StephaneDucasse' project: 'Colors'; package: 'MoreColors'; load. Color initializeNames I would really like to see how we can model the notion of color palettes. Stef

Next step will be to exceed 100 in 2018! And yes, Iâm definitely interested in a bootstrapped image ;) That is the kind of metric that I love to see.
