A modified version of the above code to show that a sub pattern can contain multiple patterns is shown below −Open Compiler #!/usr/bin/tclsh regexp {([A-Za-z]*.([A-Za-z]*))} "Tcl Tutorial" a b c puts "Full Match: $a" puts "Sub Match1: $b" puts "Sub Match2: $c" ...
Options : -exact (exact matching), -glob (same as string matching), or -regexp (regular expression matching). If a script is '-', switch use the script for next pattern (i.e. several patterns can all execute the same script). default pattern used to catch unmatched patterns. eval arg...
21、tternfilenamesetfopen$filenamerwhilegets$flineifregexp$pattern$lineputsstdout$lineclose$fopen命令返回一个字符串用于表识打开的文件。当调用别的命令(如:gets,puts,close,对打开的文件进行操作时,就可以使用这个文件标识符。TCL有三个特定的文件标识:stdin,stdout和stderr,分别对应标准输入、标准输出和错误...
还有一个更简捷的解决方法,叫做“active file(主动文件)”.原本由Nat Pryce在设计样本时想到的。这种方法基于一个非常简单的提议:与其用TCL自己来写语法分析器(用regexp或其他途径),干嘛不让TCL的语法分析器为你做这些工作呢? ▲主动文件设计样本 为解释这种设计样本,我们继续使用上节中那个简单的绘图工具。首先我们...
字符串操作因为TCL把所有的输入都当作字符串看待,所以TCL提供了较强的字符串操作功能,TCL中与字符串操作有关的命令有:string、format、regexp、regsub、scan等。format命令语法:formatformat 41、string?vluevalue.?format命令类似于ANSIC中的sprintf函数和MFC中CString类提供的Format成员函数。它按formatstring提供的格式...

Changed the Regexp object to take advantage of this extra cache. Added a reference count to the TclRegexp type so regexps can be shared by multiple objects. Removed the per-interp regexp cache from the interpreter. Now regexps can be used with no need for an interpreter. [Bug ...
