regex substitute several special characters with other special characters in Textwrangler

阅读更多关于 regex substitute several special characters with other special characters in Textwrangler

问题 The character ̈ (unicode 0x308) cannot be represented in the “Western (ISO Latin 9)” encoding. I need to replace several (3) of this special characters in many txt-files. Ideal would be one single regex command for the TEXTWRANGLER editor application I run on my Mac so I can use in the find&replace function of Textwrangler (similar to BBedit). Here are the 3 special chars: ä into ä ö into ö ü into ü (please note the first letter persists of two chars (e.g. the a and the ̈ unicode 0x308)

Text Editor which tells the index of the cursor position

阅读更多关于 Text Editor which tells the index of the cursor position

问题 I need a text editor which tells me the position of the cursor (so I can determine ranges of text to then load into strings). Unfortunately the text editors ive tried (TextWrangler, Aquamacs, EditPad) only tell me the line number the cursor is on, and the character index on that line. I need the index from the beginning of the file to that point - ie the absolute index. Any recommendations for an editor (or a technique im missing in the editors ive already got) which can tell me this? 回答1: If

More efficient R / Sweave / TeXShop work-flow?

问题 I've now got everything to work properly on my Mac OS X 10.6 machine so that I can create decent looking LaTeX documents with Sweave that include snippets of R code, output, and LaTeX formatting together. Unfortunately, I feel like my work-flow is a bit clunky and inefficient: Using TextWrangler, I write LaTeX code and R code (surrounded by <<>>= above and @ below R code chunk) together in one .Rnw file. After saving changes, I call the .Rnw file from R using the Sweave command Sweave(file="

Replacing digits immediately after a saved pattern

阅读更多关于 Replacing digits immediately after a saved pattern

问题 Searched pattern looks like text9 I search for (text)9 I want to replace with \15 so that I would get text5 but instead it's just giving me text . Any other character works except for digits. 回答1: As it turns out, the PCRE-style back-references do not work. So, you have to use \015 to replace with the text captured with the first capturing group ( \01 ) and 5 . Since there cannot be more than 99 capturing groups, and both the digits after \ are treated as back-reference group number, \01 is
