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.

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