Question

即使使用正则表达式/ Sublime Text 2也不确定是否可行。想要获取一行的第一个（正）值（1759）并将其复制到注释格式的每个相关行的末尾。复制到所有（负值＆＃34; B＆＃34;行，直到下一个/新的正线，其中正值（1753）被复制到相关行。我有超过1600行使用此格式进行评论，想知道是否有一种比手动输入每种方法更快的方法。注意＆＃34; B＆＃34;线与＆＃34; C＆＃34;线无关。

s(1759,"B 1",{99168,99157,99158,99159,105779,105792},4) 
s(-1764,"B 2 (L)",{105819,105140,104956,105141,105086,105119},nil) 
s(-1763,"B 3 (R)",{99086,99080,99081,99082,105086,105119},4) 
s(-1762,"B 4 (L)",{105432,105638,105454,105639,105584,105617},nil) 
s(-1761,"B 5 (R)",{99406,99402,99403,99404,105584,105617},4) 
s(-1760,"B 6 (L)",{105183,105809,105754,105800,105779,105792},nil)
s(1753,"C",{105161,99108,99109,99104,105784,105790},64)
s(-1755,"C (R)",{105410,99352,99353,99354,105597,105598},64)
s(-1754,"C (L)",{105329,105161,105259,105404,105755,105784,105790},nil)

成：

s(1759,"B 1",{99168,99157,99158,99159,105779,105792},4) --1759 
s(-1764,"B 2 (L)",{105819,105140,104956,105141,105086,105119},) --1759

Answer 1

这是我能用ST做的最接近你想做的事找到什么：s\((?<!\-)(\d+)(.+\n)(?:((?:s\((?=\-).+\d+\n)+)|(s\((?=\-).+))+
替换为：s($1$2$3$4 --$1

你必须多次运行它，因为它一次只能运行一次。

Answer 2

我认为，使用正则表达式替换无法完成此任务。

我没有使用Sublime文本编辑器，因此无法提供可与此文本编辑器一起使用的解决方案。

但是，也许还有其他人有类似的任务，因此为文本编辑器UltraEdit提供脚本解决方案。

以下UltraEdit脚本将输入数据重新格式化为输出数据。

if (UltraEdit.document.length > 0)  // Is any file opened?
{
   // Define environment for this script.
   UltraEdit.insertMode();
   UltraEdit.columnModeOff();

   // Check if last line of file has a line termination and if this
   // is not the case, append a line termination to end of the file.
   UltraEdit.activeDocument.bottom();
   if (UltraEdit.activeDocument.isColNumGt(1))
   {
      UltraEdit.activeDocument.insertLine();
   }
   // Move caret to top of the active file.
   UltraEdit.activeDocument.top();

   // Select Perl regular expression engine.
   UltraEdit.perlReOn();

   // Define once all find and replace parameters
   // not changed during execution of the script.
   UltraEdit.activeDocument.findReplace.matchCase=true;
   UltraEdit.activeDocument.findReplace.matchWord=false;
   UltraEdit.activeDocument.findReplace.regExp=true;
   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;

   UltraEdit.activeDocument.findReplace.mode=0;   // Find in current file.

   // Run the following loop until no line is found anymore up to
   // end of the file starting with "s(" and a positive number.
   while(UltraEdit.activeDocument.findReplace.find("^s\\(\\d+"))
   {
      // Copy just the found number into a string variable
      var sNumber = UltraEdit.activeDocument.selection.substr(2);
      // Remember the number of the current line.
      var nBlockBegin = UltraEdit.activeDocument.currentLineNum;
      // Run the same find as before to find next line starting with "s("
      // and a positive number to determine the lines of the block to modify.
      if(!UltraEdit.activeDocument.findReplace.find("^s\\(\\d+"))
      {
         UltraEdit.activeDocument.bottom();
      }
      var nNextBlock = UltraEdit.activeDocument.currentLineNum;

      // Select from current position of caret to beginning of the block.
      UltraEdit.activeDocument.gotoLineSelect(nBlockBegin,1);
      UltraEdit.activeDocument.endSelect();

      // The following Replace All is done only on selected lines.
      UltraEdit.activeDocument.findReplace.mode=1;

      // On all selected lines ending with "nil)" or just with ")" and
      // optional spaces/tabs remove "nil" and append " --" and the number.
      UltraEdit.activeDocument.findReplace.replace("(?:nil)?\\)[ \\t]*$", ") --"+sNumber);

      // Switch back to a find in current file.
      UltraEdit.activeDocument.findReplace.mode=0;

      // Move caret to beginning of next block or end of file.
      UltraEdit.activeDocument.gotoLine(nNextBlock,1);
   }
   UltraEdit.activeDocument.top();
}

我使用UltraEdit v21.10.0.1027在输入数据示例上测试了此脚本。

PS：您的输出数据有点不一致。在以1759结尾的行上，--和数字之间没有空格，而在以1753结尾的行上，--后面有一个空格。在3行nil被删除，但不在输出数据示例的最后一行。

从源文件创建file1.txt（插入所有1600行）：

file1.txt

local comment, group
print((([[
s(1759,"B 1",{99168,99157,99158,99159,105779,105792},4)
s(-1764,"B 2 (L)",{105819,105140,104956,105141,105086,105119},nil)
s(-1763,"B 3 (R)",{99086,99080,99081,99082,105086,105119},4)
s(-1762,"B 4 (L)",{105432,105638,105454,105639,105584,105617},nil)
s(-1761,"B 5 (R)",{99406,99402,99403,99404,105584,105617},4)
s(-1760,"B 6 (L)",{105183,105809,105754,105800,105779,105792},nil)
s(1753,"C",{105161,99108,99109,99104,105784,105790},64)
s(-1755,"C (R)",{105410,99352,99353,99354,105597,105598},64)
s(-1754,"C (L)",{105329,105161,105259,105404,105755,105784,105790},nil)
]]):gsub('(s%((.-),"(%w+).-)\n',
   function(line, next_comment, next_group)
      if group ~= next_group then
         group = next_group
         comment = next_comment
      end
      return line..' -- '..comment..'\n'
   end
)))

并在Lua中执行

lua file1.txt > file2.txt

之后file2.txt将包含修改后的代码

正则表达式复制第一个值
