新闻 GNU Guile 2.1.3 发布，Scheme 实现 下载

GNU Guile 2.1.3 发布，Scheme 是一种编程语言，而 Guile（Scheme 解释器和库）将它转换成嵌入式脚本语言，从而很好地将动态性引入到静态应用程序中。现在我们将快速概览 Guile，发现它在构建可扩展应用程序方面的强大特性。

主要更新如下：

重要更新：

• 
  Complete overhaul of port internals
  
  
• 
  All ports are now buffered, can be targets of `setvbuf'
  
  
• 
  Support for non-blocking I/O
  
  
• 
  Removal of port locks
  

新接口：

• 
  `TCP_NODELAY' and `TCP_CORK' socket options, if provided by the system
  
  
• 
  `scm_c_put_latin1_chars', `scm_c_put_utf32_chars'
  

新弃用：

• 
  ** `_IONBF', `_IOLBF', and `_IOFBF'
  

不兼容修复

• 
  Decoding errors do not advance the read pointer before erroring
  
  
• 
  Decoding errors with `substitute' strategy return U+FFFD
  
  
• 
  API to define new port types from C has changed
  

• 
  Remove `scm_set_port_mark'
  
  
• 
  Remove `scm_set_port_equalp'
  
  
• 
  Remove `scm_set_port_free'
  
  
• 
  Remove `scm_set_port_end_input', `scm_set_port_flush'
  
  
• 
  Change prototype of `scm_make_port_type'
  
  
• 
  Change prototype of port `close' function
  
  
• 
  Port and port type data structures are now opaque
  
  
• 
  Port types are now `scm_t_port_type*', not a tc16 value
