问题描述
我想用"[1]"向后替换"\ cite {foo123a}".到目前为止，我已经可以使用以下命令替换文本
I want to replace "\cite{foo123a}" with "[1]" and backwards. So far I was able to replace text with the following command
body.replaceText('.cite{foo}', '[1]');
但是我没有设法使用
body.replaceText('\cite{foo}', '[1]');
body.replaceText('\\cite{foo}', '[1]');
为什么?
我根本无法上班的反向转换
The back conversion I cannot get to work at all
body.replaceText('[1]', '\\cite{foo}');
这将仅替换"1"而不是[]，这意味着[]被解释为正则表达式字符集，转义它们将无济于事
this will replace only the "1" not the [ ], this means the [] are interpreted as regex character set, escaping them will not help
body.replaceText('\[1\]', '\\cite{foo}');//no effect, still a char set
body.replaceText('/\[1\]/', '\\cite{foo}');//no matches
文档说明
我可以找到受支持的内容的完整描述，而在某处却找不到?
Can I find a full description of what is supported and what not somewhere?
推荐答案
我对Google Apps脚本不熟悉，但这看起来像普通的正则表达式麻烦.
I'm not familiar with Google Apps Script, but this looks like ordinary regular expression troubles.
您的第二次转换不起作用，因为字符串文字'\ [1 \]'与'[1]'相同.您想将文本 \ [1 \] 引用为字符串文字，这意味着'\\ [1 \\]'.字符串文字中的斜杠没有相关含义；在这种情况下，您编写的模式与文本/1/匹配.
Your second conversion is not working because the string literal '\[1\]' is just the same as '[1]'. You want to quote the text \[1\] as a string literal, which means '\\[1\\]'. Slashes inside of a string literal have no relevant meaning; in that case you have written a pattern which matches the text /1/.
您的第一次转换不起作用，因为 {...} 表示量词，而不是直括号，因此您需要 \\\\ cite \\ {foo \\} .(这四个反斜杠是因为在正则表达式中匹配文字 \ 是 \\ ，并使其成为字符串文字是 \\\\ —两个转义的反斜杠.)
Your first conversion is not working because {...} denotes a quantifier, not literal braces, so you need \\\\cite\\{foo\\}. (The four backslashes are because to match a literal \ in a regular expression is \\, and to make that a string literal it is \\\\ — two escaped backslashes.)
