A progress indicator for code blocks in org-mode

A progress indicator for code blocks in org-mode courtesy

(Go Lang) The Go Developers Almanac

Go is a very enticing language. Not having taken more than a light jump into it, it has all the brevity of what I remember as a student learning C combined with the modern library support of Python today. Wanting to find the Go equivalent of The Java Developers Almanac, I ended up at socketloop.com. It has short and sweet articles, just like the language, and just like the author.

What all of those org-babel functions do

For the lazy org users like myself who want to know what the functions
listed here do, just evaluate the one you want: 

(describe-function 'org-babel-execute-src-block)
(describe-function 'org-babel-open-src-block-result)
(describe-function 'org-babel-load-in-session)
(describe-function 'org-babel-pop-to-session)
(describe-function 'org-babel-previous-src-block)
(describe-function 'org-babel-next-src-block)
(describe-function 'org-babel-execute-maybe)
(describe-function 'org-babel-open-src-block-result)
(describe-function 'org-babel-expand-src-block)
(describe-function 'org-babel-goto-src-block-head)
(describe-function 'org-babel-goto-named-src-block)
(describe-function 'org-babel-goto-named-result)
(describe-function 'org-babel-execute-buffer)
(describe-function 'org-babel-execute-subtree)
(describe-function 'org-babel-demarcate-block)
(describe-function 'org-babel-tangle)
(describe-function 'org-babel-tangle-file)
(describe-function 'org-babel-check-src-block)
(describe-function 'org-babel-insert-header-arg)
(describe-function 'org-babel-load-in-session)
(describe-function 'org-babel-lob-ingest)
(describe-function 'org-babel-view-src-block-info)
(describe-function 'org-babel-switch-to-session-with-code)
(describe-function 'org-babel-sha1-hash)
(describe-function 'org-babel-describe-bindings)
(describe-function 'org-babel-do-key-sequence-in-edit-buffer)

There are some very special functions in there!

The Standard Function Library

The SFL (Standard Function Library) from iMatix is a portable function library for C/C++ programs. The SFL is the result of many years’ development, and is provided as Open Source software for the benefit of the Internet community.

The SFL provides about 450 functions that cover these areas:
Compression, encryption, and encoding;
Datatype conversion and formatting;
Dates, times, and calendars;
Directory and environment access;
User and process groups;
Inverted bitmap indices;
Symbol tables;
Error message files;
Configuration files;
String manipulation and searching;
File access;
Internet socket access;
Internet programming (MIME, CGI);
SMTP (e-mail) access;
Server (batch) programming;
Program tracing.

It is free software.
