Decoding Mobile Development Options

Decoding Mobile Development Options

Mike Cerny Articles, Development Technologies & Tools, Mobile, React Native, Xamarin 1 Comment

It can be challenging to decide on the right strategy for reaching the mobile audience, though. If you decide an app is what you need, the next question is “what are my options?” In general terms, the types of mobile applications you could choose to build can be divided into three groups: vendor-native, cross-platform, and hybrid web.

In this post, we give an overview of the various mobile development strategies on our shortlist for enterprise clients to consider; for example, Xamarin, Flutter, React Native, and Ionic. For each tool, we give a brief introduction and highlight the key advantages and disadvantages found in implementing each mobile development approach.

Expression Parser with Antlr4

An Antlr4-Based Expression Parser

Lou Mauget Articles, Development Technologies & Tools, Java, Programming, Python 1 Comment

In this blog, we’ll present a simple arithmetic expression parser implemented through an Antlr4 parser generator. It will be able to take in an input string (such as 2+4+-4+-2*10%9*7) to produce the result (-12.0).

You may be thinking, “Great, but what’s the point?” Well, to answer your question, as simple as this example may seem, the principles involved actually extend to use cases such as DSLs, transpilation, and anything else expressible by grammar rules.

This post has two parts. In part 1, we’ll discuss the background components of a parser. In part 2, we’ll cover building the demo and running it. If you already understand grammar parsing, you could skip part one.
