ZSH iterm2 increase number of lines history

itermiterm2terminalzsh

Not sure if this is zsh, iterm2 or the interaction between them.
Trying to change the number of recallable lines in the terminal – not the command history, the output history.

In .zshrc I have :

HISTFILE=~/.histfile
HISTSIZE=100000
SAVEHIST=100000

This seems to be ignored =(

Not sure of the correct term to google, "Terminal output history?"

It's not immediately obvious in the iTerm2 documentation on how to change it.

open the iTerm2 preferences ⌘ + ,
select the Profiles tab
then select the Terminal subtab
Beware, changes to the Scrollback lines value take effect immediately so check Unlimited scrollback now if you don't want to delete your current buffer(s)
change the value of the Scrollback Lines to whatever you'd like
Uncheck the Unlimited scrollback option if you'd like to use your Scrollback lines value

Macos – Incorrect colors with vim in iTerm2 using Solarized

A couple of things to check:

In iTerm2, in Preferences -> Profiles -> Terminal, under "Terminal Emulation" you have "Report Terminal Type:" set to xterm-256color.

In your .vimrc, there are some options you can also set to make sure it's using 256 colors:

set background=dark
" solarized options 
let g:solarized_visibility = "high"
let g:solarized_contrast = "high"
colorscheme solarized

And one of those should work, but #1 first.

BUT, if you're using the default, built in vim on Snow Leopard, it won't work, as it's not built with support for 256 colors. I believe the built in version in Lion does.

Edit: Based on several comments on this answer, I've removed let g:solarized_termcolors = 256 line from the .vimrc example above. It appears that could be a problem for some. Another says that adding the line let g:solarized_termcolors = 16 fixed a color display problem. Your own mileage may vary.

Second Edit: If you've loaded the solarized color palette into iTerm2, then you must let g:solarized_termcolors=16. Only let g:solarized_termcolors=256 if you are not using the solarized palette as your iTerm2 color preset.
