What is ANTLR? ANTLR (ANother Tool for Language Recognition), is an ALL(*) parser generator. In layman’s terms, Antlr, creates parsers in a number of languages (Go, Java, C, C#, Javascript), that can process text or binary input.
Useful Programs I’ll start this post with a bold but fairly uncontroversial statement: Programs that do not interact with the outside world are useless - they do nothing except consume cycles.
In this post, I will tell a story of how I had to build a custom JSON unmarshaler for the needs of a GraphQL client library in Go.
One of the common criticisms of the GOPATH is that it is hard to create isolated development environments without resorting to hacks, bash scripts, multiple GOPATH settings, or other trickery.
A few months ago, we switched over to using dep to manage dependencies for Veneur. We were excited to discover that dep provided a straightforward workflow for a longstanding problem in Go development: managing forks of dependencies and contributions to upstream projects.
I had always been a bit confused as to how the crypto/rand package and the math/rand package were related, or how they were expected to work (together).
Chat tools have been good friends of developers. On chat tools we share our thoughts, problems, solutions, jokes, and pretty much everything we do as software engineers.
Your managers, all through the hierarchy, love circulating spreadsheets via email. (They simply don't know better.) How to extract and analyze the relevant data from the daily mess? Go can help.
A regular hash function turns a key (a string or a number) into an integer. Most people will know them as either the cryptographic hash functions (MD5, SHA1, SHA256, etc) or their smaller non-cryptographic counterparts frequently encountered in hash tables (the map keyword in Go)...
