i3lock - improved screen locker

This is just a re-patched version of i3lock with the commits from i3lock-color; all the credit for the color functionality goes to eBrnd !

i3lock is a simple screen locker like slock. After starting it, you will see a white screen (you can configure the color/an image). You can return to your screen by entering your password.

Many little improvements have been made to i3lock over time:

i3lock forks, so you can combine it with an alias to suspend to RAM (run "i3lock && echo mem > /sys/power/state" to get a locked screen after waking up your computer from suspend to RAM)
You can specify either a background color or a PNG image which will be displayed while your screen is locked.
- You can also specify additional color options with the following command-line options:
  - --insidevercolor=rrggbbaa -- Inside of the circle while the password is being verified
  - --insidewrongcolor=rrggbbaa -- Inside of the circle when a wrong password was entered
  - --insidecolor=rrggbbaa -- Inside of the circle while typing/idle
  - --ringvercolor=rrggbbaa -- Outer ring while the password is being verified
  - --ringwrongcolor=rrggbbaa -- Outer ring when a wrong password was entered
  - --ringcolor=rrggbbaa -- Outer ring while typing/idle
  - --linecolor=rrggbbaa -- Line separating outer ring from inside of the circle
  - --separatorcolor=rrggbbaa -- Lines delimiting the highlight segments
  - --textcolor=rrggbbaa -- Text ("verifying", "wrong!")
  - --keyhlcolor=rrggbbaa -- Keypress highlight segments
  - --bshlcolor=rrggbbaa -- Backspace highlight segments
  - --line-uses-ring, -r -- the line between the inside and outer ring uses the ring color for its color
  - --line-uses-inside, -s -- the line between the inside and outer ring uses the inside color for its color
- The following additional options have been added:
- -S, --screen -- specifies which display to draw the unlock indicator on
- -k, --clock -- enables the clock display.
  - --indicator -- forces the indicator to always show, even if there's no activity.
  - --no-composite -- disables checking for compositors and trying to grab the compositor window, since that causes issues with some compositors.
    - NOTE: This can potentially allow sensitive information to display over the screen locker, so take care when you use this option.
- -B=sigma, --blur -- enables Gaussian blur. Sigma is the blur radius.
  - Note: You can still composite images over the blur (but still under the indicator) with -i. - Eventually there might be an imagepos arg, similar to time and datepos.
- --timestr="%H:%M:%S" -- allows custom overriding of the time format string. Accepts strftime formatting. Default is "%H:%M:%S".
- --timepos="ix:iy-20" -- position of the time. Expressions using the variables x (current screen's x value), y (current screen's y value), w (screen width), h (screen height), ix (indicator x position), iy (indicator y position) cw (clock width), and ch (clock height) can be used..
- --timecolor=rrggbbaa -- color of the time string
- --timefont="sans-serif" -- font used for the time display
- --timesize=32 -- font size for the time display
- --datestr="%A, %m %Y" -- allows custom overriding of the date format string. Accepts strftime formatting. Default is "%A, %m %Y".
- --datepos="ix:iy-20" -- position of the date. All the variables in timepos can be used here, as well as the additional values tx (time x) and ty (time y).
- --datecolor=rrggbbaa -- color of the date string
- --datefont="sans-serif" -- font used for the date display
- --datesize=14 -- font size for the date display
  - --veriftext="verifying…" -- text to be shown while verifying
  - --wrongtext="wrong!" -- text to be shown upon an incorrect password being entered
  - --textsize=28 -- font size for the status text
  - --modsize=14 -- font size for the modifier keys listing
  - --radius=90 -- the radius of the circle indicator
You can specify whether i3lock should bell upon a wrong password.
i3lock uses PAM and therefore is compatible with LDAP etc. On OpenBSD i3lock uses the bsd_auth(3) framework.

Running i3lock

Simply invoke the 'i3lock' command. To get out of it, enter your password and press enter.

A sample script is included in this repository. Here is a short clip of that script in action!

On OpenBSD the i3lock binary needs to be setgid auth to call the authentication helpers, e.g. /usr/libexec/auth/login_passwd.
