We are very happy to announce the website of Tidier, an automatic
refactoring tool for Erlang programs.

Tidier cleans up Erlang source code and suggests to its user a sequence
of transformations that improve the quality and performance of code.

More information about tidier can be found at its website (*):

We welcome feedback and suggestions!

Kostis Sagonas and Thanassis Avgerinos

俺很期待的东西.试验了下,可以上传erl文件或者整个项目的包上去, tidier果然很争气的找出有问题或者需要改进的地方
,效果相当的好. Erlang R13B04的代码都是经过tidier的. 唯一不好一点就是不开源,使用上有点受限,但是我们还是很感激的.

一起来吧从这里开始: http://tidier.softlab.ntua.gr:20000/tidier/getstarted

Erlang/OTP R13B04 has been released. R13B04 is a service release for R13B. There are mostly error corrections, but also some new functionality.
This is the first release after the introduction of the official Git repository at Github and it is amazing to notice that the number of contributions from the community has increased significantly. As many as 32 contributors have provided 1 or more patches each until now, resulting in 51 integrated patches from the open source community in this service release.
In addition to the contributions provided by the community we have the following examples of highlights in the release:

* The documentation can now be built from the source.
* The Native Implemented Functions (NIFs) are still in beta, but much enhanced.
* The garbage collection of binaries is further enhanced.
* Support for user defined prompt in the shell. A small but useful new function.
* Enhanced cross compilation support

*BUG fix版本,细细碎碎的改进了不少. 添加了个lcnt工具

本文链接地址: R13B04 Add lock profiling tool: lcnt

在调试版本下 这个工具可以直观的看出你的Erlang程序所用到的锁,对于诊断问题和提高性能非常有帮助.

OTP-8424 Add lock profiling tool.

The Lock profiling tool, lcnt, can make use of the internal lock
statistics when the runtime system is built with this feature
enabled.

This provides a mechanism to examine potential lock bottlenecks
within the runtime itself.

– Add erts_debug:lock_counters({copy_save, bool()}). This option
enables or disables statistics saving for destroyed processes and
ets-tables. Enabling this might consume a lot of memory.

– Add id-numbering for lock classes which is otherwise undefined.
