ReadLine

You first step through the file line by line using the readline method .

首先，用readline方法在文件行中移动。

These factors make it impossible to implement even a simple readline method without polling .

这些因素使得没有轮询就不可能实现甚至是简单的readline方法。

All servlet containers must provide a readline method on their input streams .

所有的servlet容器必须在它们的输入流上提供readline方法。

The bash shell uses the readline library to manage command editing and history .

bashshell使用readline历史来管理命令编辑和历史。

When you reach the end of the file , the readline method returns an empty string .

当到达文件末尾时，readline方法返回一个空的string。

The readline method , however , reads the specified number of characters and continues reading until the end of that line .

但是readline方法在读入指定数量的字符后，还会继续读取，直到行尾。

By using this knowledge , you can pass in a parameter to the read method or the readline method to control how many characters are read .

通过使用这个知识，可以向read或readline方法传递一个参数，控制读取的字符数。

Gnuplot can be recompiled to use the GNU readline library to move around on the input prompt , but the defaults function similarly .

可以对gnuplot进行重新编译以便使用GNUreadline库在输入提示符上来回移动，但类似于默认函数。

Not only that , but we substituted certain dependencies like GNU Readline with a pure-ruby version called rb-readline .

并不仅仅是这些，我们将会替代一些依赖程序，例如使用纯净的ruby版readline（叫做rb）来替代GNU的Readline。

The difference between . readline () and . readlines () is that the latter , like . read (), reads an entire file at once .

readline（）和.readlines（）之间的差异是后者一次读取整个文件，象.read（）一样。

More extensive commands , such as going backward and forward by words , are controlled by the Readline library that supports both vi and emacs bindings by default .

更广泛的命令（例如按单词向前和向后移动）可以通过Readline库来控制，该库在缺省情况下同时支持vi和emacs绑定。

Additional functions as well as how to customize these options using a readline init file ( usually inputrc in your home directory ) can be found in the man pages .

其余功能以及如何使用readlineinit文件（通常为主目录中的inputrc）定制选项等内容可以在手册页中找到。

I should also mention that the Term : : ReadLine : : Gnu CPAN module works better for me than the default module , Term : : ReadLine : : Perl , in Linux inside xterm and Eterm terminal emulators .

我还应提一下，在Linux内部的xterm和Eterm终端模拟器中，Term：：ReadLine：：Gnu模块比默认模块Term：：ReadLine：：Perl能更好地工作。
