Capstone is a disassembly framework with the target of becoming the ultimate disasm engine for binary analysis and reversing in the security community. Running on Windows, Mac OS X, Linux, FreeBSD, OpenBSD, and Solaris, it can disassemble ARM, ARM64 (ARMv8), MIPS, PPC, and x86 architectures. Capstone provides rich details about disassembled instructions along with useful semantic information.
form is a library designed to allow seamless, high-fidelity encoding and decoding of arbitrary data in application/x-www-form-urlencoded format and as url.Values. It is intended to be useful primarily in dealing with Web forms and URI query strings, both of which natively employ said format. Unsurprisingly, form is modeled after other Go encoding packages, in particular encoding/JSON, and follows the same conventions (see below for more.) It aims to automatically handle any kind of concrete Go data value (i.e., not functions, channels, etc.) while providing mechanisms for custom behavior.
WapSNMP is an SNMP client library for Go. It allows you to query SNMP servers for any variable, given its OID (no MIB resolution). It has been written to be in the Go style, which means it should be very resistant to all error conditions. It's entirely non-blocking/asynchronous, very fast, and will timeout, not block. It's also surprisingly small and easy to understand. It supports SNMPv2c or lower (not 3, due to its complexity), and supports all methods provided as part of that standard. This library works with OIDs and does not support OID-to-name translation.
Csum is a tool for manipulating CSV, TSV, PSV and other table formats for the command line. It can be used for converting between several formats; selecting and manipulating cells matching a selector; inserting or rearranging columns; sorting, reversing, or selecting unique rows; rotating rows so they become the columns of the table; and more. It was designed for environments where the use of a graphical spreadsheet to edit a CSV file was not possible or practical.
