Misc Erlang Tools

Sequences / Iterators:

• fold: folds
• pfold: partial folds
• sink: push-style data consumer callbacks
• igen: impure generators
• iseq: infinite sequences implemented as thunks
• source: pure, idempotent sequences

Core abstractions and algorihtms

• obj: processes with Map state
• type_base: serializable data types
• tools: grab bag of function
• diff: compute datastructure diffs
• run: running scripts

Distributed systems:

• epid: multi-hop pids for fine grained objects / processes + dataflow abstraction
• throttle: data throttling

TCP

• serv: simple server tools
• serv_tcp: simple tcp server with connection list
• http: gen_tcp wrappers
• cowboy_wrap: wrappers for cowboy web server

Networking tools

• reverse_tunnel: e.g. for reverse SSH (not what you think)
• socks_proxy: socks5 proxy server
• bert_rpc: BERT RPC support
• ssh_leaf: interacti with ssh machine (commands, rsync, log events)

Web

• ws: erl<->js comm protocol based on WebSockets on top of cowboy
• ws_widget: actor based web widgets on top of ws
• ws_layout: layout functions for ws_widget style web widgets.
• exml: misc exml functions
• serv_ws: stand-alone websocket server
• stack_ws: forth-based websocket protocol for serv_ws

Database

• sqlite: SQLite wrappers
• kvstore: generic key value store interface
• sqlite_kvstore: kvstore on top of sqlite wrapper
• sqlite3_ckeys: composite key store on top of sqlite

Microcontroller development, See also uc_tools/gdb

• rsp: GDB RSP protocol
• gdbstub: gdb stub in Erlang (wip)
• gdbstub_hub: server for gdbstubs
• gdb: gdb MI access
• lab_board: driver for uc_tools/gdb based lab control boards
• tag_u32: Simple structured binary message format + directory structure
• leb128: Efficient storage format for tag_u32 structures based on LEB128 integers
• epid_cproc: C code generation for cproc.h dataflow networks
• epid_dag: Erlang-embedded higher order abstract syntax for distributed dataflow networks

Logging

• recorder: log file recording (also used for a/v recording)
• player: log file player (also for a/v playback)

Development support

• expect: Use Erlang parser to create "expect tests"
• hs: Haskell bindings
• redo: implementation of Redo build system in Erlang
• reflection: Code handling Erlang and other language compilation
• ghcid/ghci: interact with GHCId and GHCI
• emacs: emacs interfacing

Low level drivers

• gpio_poll: map gpio events to Erlang events (erl/C)
• v4l: Video For Linux (erl/C)
• ftdi/ftdi_hub: manage multiple FTDI connections (e.g. uC dev boards)
• rigol: interface with Rigol oscilloscope
• linux: misc linux system interfacing

And some doodles that are not worth mentioning.
