iterm_control

Using escape sequences iTerm2 can be controlled from fish-shell - in some aspects.

This plugin wraps around the escape codes to give some comfort:

• Change some colors
• Set title of tab
• Set marks on the buffer
• Change cursor shape
• Adjust color of the chrome (title and tab bar colors).

Security

Changing colors and setting marks should not be an issue.

But the code reads:

Disable potentially insecure escape sequences

RemoteHost, StealFocus, CurrentDir, SetProfile, CopyToClipboard, EndCopy, File, SetBackgroundImageFile

While the supplied functions for SetProfile and StealFocus work

• if the related setting ('Advanced: Disable potentially insecure escape sequences') is not enabled

it is recommended to leave these cosmetical set of dangerous features off. Therefore, they are commented out.

What is dangerous?

There might be bugs lurking in the iTerm2 codebase - this is why the actual authors allow to keep it disabled.

Install

Usage

While iterm_set_mark can be called as a function it is recommended to emit events:

emit iterm_set_mark

Personally, i consider this feature to be most useful.

Change cursor to vertical bar:

iterm_set_cursor_shape 1

Change title and tab bar to red, like when an error occurs:

iterm_set_chrome 196 000 000
sleep 1
iterm_reset_chrome

Switch the background color in accordance to day or night time:

iterm_set_tab_title 'day'
iterm_set_background f0f0f0
iterm_set_foreground 040404
sleep 5 # alien planet has a daycycle of 5 seconds
iterm_set_tab_title 'night'
iterm_set_background 040404
iterm_set_foreground ffffff

Well, at least something. As stated above only SetProfile would allow changing the color theme as set by each profile.

Security-wiese folks might code-audit iTerm2 so these features could be enabled with less risk.
