Hi. dear frend!
This is my question.
I'm trying to use the coolstr package. Like this.

coolstr_expl.tex

Code: [Select all] [Expand/Collapse] [Download] ({untitled.tex}) Open in Overleaf

\documentclass[10pt]{article}
\usepackage{coolstr}
 
\newcommand{\simv}[2]{
     \ifstrchareq{#1}{#2}{A}{10}{
      \ifstrchareq{#1}{#2}{B}{11}{
       \ifstrchareq{#1}{#2}{C}{12}{
        \substr{#1}{#2}{1}}}}}
 
\begin{document}
 
\simv{C2A3B}{1}
\simv{C2A3B}{2}
\simv{C2A3B}{3}
\simv{C2A3B}{4}
\simv{C2A3B}{5}
 
\end{document}

However, instead of 12210311 I get this: 12 2 10 3 11

For some reason, there are extra spaces.
What am I doing wrong?
Thank!
Best regards!

Hi kabenyuk,

welcome to the forum!

The end of the line is considered as a space. In the document code, If a word is at the end of a line and another word follows on the next line, there will be a space in the output between the words. Since line ends are considered as a space, macro authors very often add a percent sign at the end of the line to comment that space out. That's how you can fix it, comment out the line end by %:

\documentclass[10pt]{article}
\usepackage{coolstr}
 
\newcommand{\simv}[2]{%
\ifstrchareq{#1}{#2}{A}{10}{%
\ifstrchareq{#1}{#2}{B}{11}{%
\ifstrchareq{#1}{#2}{C}{12}{%
\substr{#1}{#2}{1}}}}}
 
\begin{document}
 
\simv{C2A3B}{1}%
\simv{C2A3B}{2}%
\simv{C2A3B}{3}%
\simv{C2A3B}{4}%
\simv{C2A3B}{5}
 
\end{document}
