I agree that the equal function on the vector prototype is the best solution. Note that you can also build other infix-like operators via chaining. function Vector(x, y, z) { this.x = x; this.y = y; this.z = z; } Vector.prototype.add = function (v2) { var v = new Vector(this.x + v2.x, this.y + v2.y, … Read more
Pyparsing is handy for writing “little languages”. I gave a presentation at PyCon’06 on writing a simple adventure game engine, in which the language being parsed and interpreted was the game command set (“inventory”, “take sword”, “drop book”, etc.). (Source code here.) You can also find links to other pyparsing articles at the pyparsing wiki.
I used LIME Parser generator for PHP a couple of years ago, and it was already mature and stable. The parser generator itself is written in PHP, which doesn’t really matter in any technical sense – as we require only that the generated parser be in PHP – but I like this detail nonetheless. It … Read more
I went ahead and downloaded the project from the link you provided: http://javapapers.com/android/android-chat-bubble/ Since this is an old tutorial, you simply need to upgrade the software, gradle, the android build tools and plugin. Make sure you have the latest Gradle and Android Studio: https://www.gradle.org/ http://tools.android.com/tech-docs/new-build-system/version-compatibility build.gradle: buildscript { repositories { jcenter() } dependencies { classpath … Read more
Try the karate.write(value, filename) API but we don’t encourage it. Also the file will be written only to the current “build” directory which will be target for Maven projects / stand-alone JAR. value can be any data-type, and Karate will write the bytes (or plain-text) out. There is no built-in support for any other format. … Read more
Would the dynamic linq library help here? In particular, I’m thinking as a Where clause. If necessary, put it inside a list/array just to call .Where(string) on it! i.e. var people = new List<Person> { person }; int match = people.Where(filter).Any(); If not, writing a parser (using Expression under the hood) isn’t hugely taxing – … Read more
