newcommand with node confusion [closed]

Question

I'm just getting warmed to tikz so please forgive me if this is a dumb question I want to declare an newcommand containing a node with text:

\newcommand{\mydoor}[1] {
\draw[black] (1,-1) -- (1,-0) node[right,near start] {{#1}};
}

\begin{tikzpicture}
\mydoor[mytext];
\end{tikzpicture}

The output I get is not "| mytext" but "| ["

What on earth am I missing and how can I design a simple line with a configurable text (I want to use this on a more complicated polygon, therefore the environment)?

Answer 1

The syntax is not right: twice brackets are not necessary in the command definition as the semicolon in the call of the command. Moreover the argument (the text) is mandatory, thus you should use brackets and not square brackets. Try in this way:

\documentclass{article}
\usepackage{tikz}

\newcommand{\mydoor}[1] {
\draw[black] (1,-1) -- (1,-0) node[right,near start] {#1};
}

\begin{document}
\begin{tikzpicture}
\mydoor{mytext}
\end{tikzpicture}
\end{document} 

which gives:
