[英]UltraEdit find and replace regular expression
我有下面的代码在%hostname
之后找到正则表达式,并将它替换为#hostname
所有文本。
如何复制%Location
和#Location.
我似乎无法使复制适用于多个变量。
谢谢
var host= "%hostname =(.*)"; // Perl regular expression to find title string
UltraEdit.activeDocument.top();
// Turn on regular expressions
UltraEdit.activeDocument.findReplace.regExp = true;
// Find it
UltraEdit.activeDocument.findReplace.find(host);
// Load it into a selection
var host2= UltraEdit.activeDocument.selection;
// Javascript function 'match' will match the regex within the javascript engine
// so we can extract the actual title via array
t = host2.match(host);
savehost = t[1];
UltraEdit.activeDocument.top();
UltraEdit.activeDocument.findReplace.replaceAll=true;
UltraEdit.activeDocument.findReplace.matchCase=true;
UltraEdit.activeDocument.findReplace.replace("#hostname", savehost);
这是此任务的UltraEdit脚本。
数组asVariables
包含变量的名称,您可以使用其他字符串对其进行扩展。
if (UltraEdit.document.length > 0) // Is any file opened?
{
// Define environment for this script.
UltraEdit.insertMode();
UltraEdit.columnModeOff();
// Define a constant array of variable names which can be extended
// or modified in script code at any time to support more variables.
var asVariables = [ "hostname" , "Location" ];
// Define once all find and replace options to make the
// script independent on internal defaults of UltraEdit.
UltraEdit.perlReOn();
UltraEdit.activeDocument.findReplace.mode=0;
UltraEdit.activeDocument.findReplace.matchCase=true;
UltraEdit.activeDocument.findReplace.matchWord=false;
UltraEdit.activeDocument.findReplace.searchDown=true;
if (typeof(UltraEdit.activeDocument.findReplace.searchInColumn) == "boolean")
{
UltraEdit.activeDocument.findReplace.searchInColumn=false;
}
UltraEdit.activeDocument.findReplace.preserveCase=false;
UltraEdit.activeDocument.findReplace.replaceAll=true;
UltraEdit.activeDocument.findReplace.replaceInAllOpen=false;
// Run the code in the loop on all variables defined in the array.
for (var nVariable = 0; nVariable < asVariables.length; nVariable++)
{
// Move caret to top of the active file.
UltraEdit.activeDocument.top();
// Perl regular expression to find %variable string and assigned data.
var sSearch = "%" + asVariables[nVariable] + " *?=.*$";
UltraEdit.activeDocument.findReplace.regExp=true;
// If the variable is not found in active file,
// continue immediately with next variable.
if(!UltraEdit.activeDocument.findReplace.find(sSearch)) continue;
// Get just the string after the first equal sign from selected string.
// The replace method of JavaScript String object never modifies the
// string value itself. It creates always a new string derived from
// the current string value with the replace applied.
var sData = UltraEdit.activeDocument.selection.replace(/^.*?=(.*)$/,"$1");
// Replace all occurrences of #variable by the found data in entire file.
UltraEdit.activeDocument.top();
UltraEdit.activeDocument.findReplace.regExp=false;
sSearch = "#" + asVariables[nVariable];
UltraEdit.activeDocument.findReplace.replace(sSearch,sData);
}
}
