Changing --appdir is throwing "Error: wrong constant name"

[SableRaf]

$ brew cask --appdir=/Applications
Error: wrong constant name --appdir=/applications

$ brew cask --version
0.9.5

I guess I should learn to read the manual. Nevermind :)

I'm having the same trouble; and I've literally copy-pasted this command from the README, leaving me unsure how I could “read the manual” any better.

¿Ayudarme? /=

I'm actually curious about this as well. I set up the environment variable in my .bash_profile and that gets picked up okay. However I wanted to add brew cask --appdir=/Applications to a bootstrap script of mine for future use, but it returns Error: wrong constant name --appdir=/applications

@ELLIOTTCABLE: You need to add the following line to your .bash_profile (or .zshenv if you use zshell):

export HOMEBREW_CASK_OPTS="--appdir=/Applications --caskroom=/etc/Caskroom"

Read the end of https://github.com/caskroom/homebrew-cask/blob/master/USAGE.md#options for more info.

@chrischernoff : This line of the readme is a bit misleading

brew cask accepts a number of options

Actually --appdir is not an option of brew cask itself but of brew cask install (as far as I understand). Your script should either set the environment variable or call --appdir=/applications for every install e.g. $ brew cask install --appdir="~/Applications" google-chrome

That is correct, @SableRaf.

I’ve proposed a small change in light of the confusion. What do you all think, is it clearer?

[chrischernoff]

That definitely helps @vitorgalvao. Although it does make me wonder if it would be useful for homebrew-cask to have its own config file. One could set options like --appdir via brew cask --appdir/"somewhere" and it would get written to something like .caskrc rather than having to add a line to .bash_profile / .bashrc.

[vitorgalvao]

The idea has been mentioned before. I don’t think anyone opposes it (on the contrary). Care to open an issue with the suggestion?

[ELLIOTTCABLE]

Why does it need to be a separate configuration file? Can we attach it somehow to the Homebrew configuration? (=

[alebcay]

Does Homebrew even have a configuration file?
