| 26 How to handle special characters: | |
| 27 \begin{itemize}[<+->] | |
| 28 \item You will need to quote your revsets on the command line: | |
| 29 \begin{lstlisting} | |
| 30 $ hg log -r parents() | |
| 31 zsh: parse error near `()' | |
| 32 \end{lstlisting} | |
| 33 | |
| 34 \item Strings in revsets can be in single- or double-quotes: | |
| 35 \begin{lstlisting} | |
| 36 $ hg log -r "user('Martin')" | |
| 37 \end{lstlisting} | |
| 38 | |
| 39 \item Escape characters are supported | |
| 40 \begin{lstlisting} | |
| 41 $ hg log -r "keyword('first line\nsecond line')" | |
| 42 \end{lstlisting} | |
| 43 | |
| 44 \item Use a raw string to disable the escape characters: | |
| 45 \begin{lstlisting} | |
| 46 $ hg log -r "grep(r'Bug\s*\d+')" | |
| 47 \end{lstlisting} | |
