How to see available options for homebrew formula install?
homebrew, libxml2
Solution
Use `options` first to check:
brew options libxml2
If this dose not satisfy you, edit the rb file directly, and do whatever you want to:
brew edit libxml2
Problem
I'm reading this stack overflow answer Mac user and getting WARNING: Nokogiri was built against LibXML version 2.7.8, but has dynamically loaded 2.7.3 and I just want to know where they learned about the `--with-xml2-config` option in ``` brew install libxml2 --with-xml2-config ``` so that I can verify I really want to use this option myself and so I can better solve problems with homebrew myself in the future. How can I see a description of this specific option and, more generally, find out all the available options for a formula when using brew install? I know `brew info FORMULA` gets me some stuff like that, but `brew info libxml2` only lists the options `--universal`, `--without-python`, and `--HEAD`. For more info, here is another stack overflow question that is similar to this one but different: How can i get more info about a brew formula before installing?
