ysh - The YAML Test Shell
This program is designed to let you play with the YAML.pm module in an interactive way. When you to type in Perl, you get back YAML. And vice versa.
By default, every line you type is a one line Perl program, the return value of which will be displayed as YAML.
To enter multi-line Perl code start the first line with ';' and use as many lines as needed. Terminate with a line containing just ';'.
To enter YAML text, start with a valid YAML separator/header line which is typically '---'. Use '===' to indicate that there is no YAML header. Enter as many lines as needed. Terminate with a line containing just '...'.
To read in and process an external YAML file, enter '< filename'. The ysh will also work as a standalone filter. It will read anything on STDIN as a YAML stream and write the Perl output to STDOUT. You can say (on most Unix systems):
cat yaml.file | ysh | less
If you don't want to enter your favorite options every time you enter
ysh, you can put the options into the
YSH_OPT environment variable.
Do something like this:
export YSH_OPT='-i3 -uc -L'
