Fetch 1.1 changelog

Over the past 10~ days over 190 more commits have been pushed to master and the
script has had some big changes. Thanks to everyone who has contributed, you've been
a big help.

^{New screenfetch mode}

• If w3m or imagemagick aren't installed we gracefully fallback to ascii mode.
• Automatically find the w3m-img path and fallback to ascii mode if not found. [1]
• Fix padding escape codes on BSD systems.
• Swap escape codes from \e to \033 for consistency.
• We only move the cursor to the bottom of the terminal in w3m/iterm2 rendering modes.
• Cursor position is now dynamic in ascii mode based on the height of the ascii and info text.
• If images and ascii are off, don't clear the terminal
• The script now exits correctly instead of always exiting with status code 1
• If the script exits for any reason, unhide the cursor.
• Removed duplicate blocks inside getcpu and getmemory.
• Removed --colors as it was apparently broken from day 1.
• Usage has been reformatted so that every flag has a value.

[1] Setting $w3m_img_path will make the script look there first.

Image

• Added support for displaying ascii art inside of text files.
• Added "screenfetch mode" which will display your distro's ascii art next to the info. [1]
• Added --ascii_distro to choose which distro's ascii logo to display.
• Added --ascii_colors and $ascii_colors which allow you to change the colors of the ascii art
  and distro logos. [2]
• Added --size and $image_size to set the image size in pixels.
• Rename --shuffledir and $shuffledir to shuffle_dir.
• Rename --imgtempdir and $imgtempdir to thumbnail_dir
• Removed --split_size and $split_size as they were weird and confusing to use.
• Default thumbnail directory is now $HOME/.cache/thumbnails/fetch. Thanks @tudurom
• If --image and --ascii are left empty we fallback to ascii distro mode.

Example usage of ascii from file:

fetch --ascii "path/to/ascii" --ascii_color 2

[1] How do I enable screenfetch mode?
[2] ascii_colors takes a range of colors which allows you to color every aspect of
distro and OS ascii art. For custom art the script will color the entirety of it using
the first value of ascii_colors. If ascii_colors is left empty, color will be disabled.

Config file

• Fetch now has a config file that you can share with people and keep between
  script versions! [1]
• Added --config and $config_file to specify a custom config location.
• Added --config off, --config none and $config to enable / disable config files
  at launch or in script.

Makefile

• Fetch now has a make file due to the increasing number of files,
  this allows the script to be easily installed and uninstalled on
  systems it isn't packaged for yet! [1]

[1] The script will still work just fine on its own, you'll just be missing
the distro ascii art and the automatic config creation.

Packages

• Fetch now has a Gentoo/Funtoo e-build courtesy of @z1lt0id

Stdout

• Added stdout mode which allows you to fetch info in a plain text format that works
  with lemonbar and in your scripts. You can use it by launching fetch with --stdout to print all
  functions enabled in your printinfo function. You can selectively print functions by passing
  arguments to --stdout like so:

# Print the output of all info functions enabled in printinfo
fetch --stdout

# Print the output of memory
fetch --stdout memory

# Print the output of memory and disk
fetch --stdout disk

# Print the output of all functions excluding x
fetch --stdout --disable kernel packages gtktheme

• Added --stdout_separator and $stdout_separator which takes a string and adds it
  as a separator between the output.
• Added --stdout_title and $stdout_title which allow you to toggle the title@hostname
  from appearing in the output.
• Added --stdout_subtitles which allow you to toggle the Info: titles from appearing in
  the output.

# Hiding subtitles
fetch --stdout --stdout_subtitles off

# Custom separator
fetch --stdout disk gpu --stdout_separator "  |  "

NOTE: stdout_subtitles and stdout_title only work when --stdout is used on its own
without any args.

Info

• You can now display info without a subtitle. eg. info memory
• Added --disable which allows you to stop an info line from appearing at launch.
• Added --underline and $underline which allow you to toggle visibility of the
  underline at launch and in your config.

# Stop cpu, gpu, disk and shell functions from being called
fetch --disable cpu gpu disk shell

Kernel: Added --kernel_shorthand and $kernel_shorthand to print less or more kernel info
Window Manager: Added support for $XINITRC
GTK: Fix incorrect GTK3 theme being displayed
CPU: cpu_shorthand: New substitutions
GPU: [Linux] Count the number of identical GPUs. eg. Nvidia Geforce GTX 970 x 2
Memory: [Mac OS X] Added wired memory to memory usage.

Distro:

• Added support for showing OS architecture. eg Arch Linux x86_64, Windows 7 Ultimate 64-bit [1]
• Mac OS X: Added support for showing Max OS X build version. [2]
• Windows: Distro now displays Windows edition. eg. Windows 7 Ultimate

[1] You can toggle this using --os_arch and $os_arch.
[2] You can toggle it using --osx_buildversion and $osx_buildversion.

Shell:

• Added --shell_version and $shell_version to hide/show your shell's version.
• Added --shell_path and $shell_path to hide/show the path to your shell

Birthday:

• Added birthday which prints the age of your OS install.
• Added --birthday_shorthand and $birthday_shorthand to shorten/lengthen
  the output of birthday.
• Added --birthday_time and $birthday_time to show/hide the time in the output.

Battery:

• Added battery which prints the battery usage percentage for each battery
  in your system.
• Linux: Added battery_num which allows you to choose which battery to display,
  it also takes the value all which will print all batteries line by line.
• Linux: Added battery_shorthand which when set to on prints each battery on the
  same line like so:

# battery_shorthand="on"
Battery: 10%, 5%, 67%

# battery_shorthand="off"
Battery0: 10%
Battery1: 5%
Battery2: 67%

# If there's only a single battery in the system
# we ommit the numbered title.
Battery: 10%

• NOTE: This currently doesn't support BSD systems as we have no one to help us test
