MIB Smithy SDK is a dynamic extension to Tcl/Tk (8.4+) that allows development of custom scripts for controlling SNMP agents, manipulating SMI definitions, doing conversions, and more. It is based on the core of Muonics' MIB Smithy, and the SDK supports SMIv1 and SMIv2, as well as SNMPv1/v2c/v3 with HMAC-SHA-96 and HMAC-MD5-96 authentication and DES/CBC and AES128/CFB privacy. It also provides complete read-write access to all elements of SMI/MIB Module definitions, unlike similar extensions that provide only read access to a limited subset. The SDK allows multiple discrete SMI databases and SNMP sessions, and provides all of the built-in validation and error recovery capabilites of the full product, without the visual MIB development environment.
The Aida project is two-fold: it defines a simple common markup language designed to describe structured text, and it implements a compiler that translates the Aida syntax into various target formats (HTML, LaTeX, Trac, Mediawiki, Text, Markdown, and others). The system is fast, flexible, and extensible. The core command, aida, is a strict parser (written using Bison and Flex), which analyzes files written in the Aida Markup Language and invokes callbacks in order to convert them to the target format. It embeds a Tcl language interpreter and the callbacks are written in Tcl. This makes it very easy to extend the library and to define new target formats. Furthermore, the Aida files are highly parameterizable via a header and the entire system is configurable at the admin and at the user level. It is also possible to evaluate Tcl code within an Aida file and thus create dynamic contents.
The Tcl IRCd is a small IRC server written in Tcl. It is very simple to modify. It is not a full implementation of the IRC protocol, but it's enough to create channels, talk in public or private, change topic, nick, and other basic operations. No configuration is required. The server is designed so that it can reload an updated version of itself at runtime without closing client connections.
