[galaxy-dev] Subtleties of <version_command> and escaping dollar signs

Hello all, I've just noticed that dollar signs for accessing environment variables must be escaped in the XML <command> tag, but must not be escaped in the <version_command> tag: https://github.com/peterjc/pico_galaxy/commit/4613a08139a3dfa07c3b0411ac8a91... I presume this is because <command> is parsed as a Cheetah template where dollar means a Python variable (like the input and output parameters), while for the <version_command> this does not happen? Has anyone else been caught out by this? Is it worth adding a note about this to the wiki? https://wiki.galaxyproject.org/Admin/Tools/ToolConfigSyntax Regards, Peter
