LaTeX forum ⇒ Texmaker and TeXstudio ⇒ Search & replace query with two arguments? Topic is solved

[Montag]

[editor: TeXMakerX]

Hello,

I'd like to perform a search & replace query for a command named "\suli", which is defined as

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\newcommand{\suli}[2]{\sum\limits^{#1}_{#2}}

. A document of mine is filled with this command. What I would like to achieve, is this:

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\sum_{#1}^{#2}

, meaning the arguments would get switched and the \limits-command omitted. Is there a way to do this?

Why not

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\renewcommand{\suli}[2]{\sum_{#1}^{#2}}

? That's the safest way.

Otherwise you can search for

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\\suli\{([^}]+)\}\{([^}]+)\}

And replace it with

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\sum_{\2}^{\1}

(if there are no nested latex commands in #1/2)

Hm, thank you for your reply, I appreciate it. If I understood correctly, something like

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\suli{n}{i=1}(x_{i}-\overline{x})(y_{i}-\overline{y})}

should be replaced with your query, right?
Well, it didn't work, neither with an enabled checkbox nor with a disabled checkbox for "Search for meta symbols". Did I do something wrong?

Have you enabled "Regexp"?

Last I checked, the standard version of Texmaker could not handle regular expressions in find/replace. TexmakerX can, however.

Now I did. And it worked. Thank you.
