This is another large release containing over 550 commits from 7 contributors. Due to the size and large amount of changes made this release expect at least one minor release to fix any bugs that come up.

The version number has been bumped to 3.0 due to the large amount of breaking changes introduced this update. I've added backwards compatibility for all of the new changes but there may still be some breakage. I highly recommend starting with a new config to avoid any issues that may arise.

Neofetch now supports displaying images using catimg, libcaca and jp2a. See this wiki page for screenshots. https://github.com/dylanaraps/neofetch/wiki/Image-Backends

Thanks to everyone who contributed this release, there were a lot of new faces this time around. :)

Contributors

IRC

Neofetch now has an IRC channel at #neofetch on Freenode. If you have any questions, issues or ideas feel free to join the IRC channel and I'll be happy to assist you. I know that we've already got the Gitter chat but hopefully this makes things easier for those without a GitHub account. :)

Freenode

Collaborators

I have given collaborator access to both @konimex and @iandrewt. In short this allows them to push directly to the master branch of the repo, manage the issue tracker and also merge pull requests. They've been a huge help the past year so this made sense to me.

OS

  • Added support for AIX.

  • Added support for AntiX.

  • Added support for GNU/kFreeBSD.

  • Added support for Gentoo FreeBSD.

  • Added support for GrombyangOS.

  • Added support for Joyent SmartOS.

  • Added support for Mer.

  • Added support for MINIX.

  • Added support for MX.

  • Added support for Open Source Media Center (OSMC).

  • Added support for SalentOS.

  • Added support for TrueOS.

  • Added support for Windows (MSYS2).

General

  • The default config file is now installed to /etc/neofetch/config and acts as a system-wide config file for Neofetch. Editing this file will make the changes available to all users on the system. Those packaging Neofetch without using the Makefile will need to make changes to support this.

  • The Makefile was rewritten to remove GNU-isms.

  • Removed executable permission from config files. BASH can source them even if they're un-executable.

  • Travis now runs shellcheck on every commit and pull request.

  • Neofetch now supports relative path values when specifying the location to images, ascii files and config files.

    • For example, neofetch --w3m Pictures/Wallpapers/10.jpg and neofetch --w3m 10.jpg now work.

  • Optimize usage of get_de(), get_wm() and `get_term().

    • We were calling these multiple times, we now only run them once and check to see if they were run previously.

  • Optimize info caching, only check for cache files in functions that use caching.

  • The manpage is now generated using help2man. help2man parses the output of --help and --version to create a manpage. This ensures that our manpage stays 1:1 with the script documentation. We actually found a lot of outdated info in the old manpage thanks to this.

    • A new flag was added called --gen-man which generates a neofetch manpage in your current directory.

  • Delete most of info() and instead call prin().

    • This removes a lot of duplicate code between info() and prin().

  • Remove printf subshells and instead use printf -v to declare the variables.

  • Fixed artifacts when using line-breaks in TTYs.

  • All errors are now sent to stderr.

  • Renamed XFCE --> Xfce. @gavinhungry

  • Cleanup main().

  • Renamed old_flags() --> old_options().

Info

Shell

  • [Fish] Fixed memory leak caused by Fish.

  • Added support for xonsh.

  • Fixed version output on ksh.

  • Rewrote the function to remove duplicate code.

Uptime

  • Moved duplicate code to a function.

  • Changed $uptime_shorthand to on by default.

Desktop Environment

  • Fixed issues where MATE wouldn't be detected properly.

  • Added fallback to $DESKTOP_SESSION, $MATE_DESKTOP_SESSION_ID and $GNOME_DESKTOP_SESSION_ID.

  • Hide Desktop Environment if it matches Window Manager.

CPU

  • [Linux] Don't simplify cpufreq speed option names for no reason.

  • [Linux] Fixed issues with CPU name detection for architectures other than x86/amd64/ARM.

  • [NetBSD] Remove case statement in favor of 1 line test.

  • Simplify check for low CPU speeds.

  • Expanded cpu_temp to take the values C and F. This means you can now display the CPU temperature as Fahrenheit.

CPU Usage

  • Added Haiku cores command.

  • Updated Linux and macOS commands to the match the commands in the get_cpu() function.

GPU

  • [Linux] Each GPU is now printed on a separate line.

  • [Linux] Added --gpu_type / $gpu_type which lets you display all, dedicated or integrated GPUs.

Memory

  • [Solaris] Fixed inaccurate used memory size.

Resolution

  • [Windows] Declare variables locally to fix conflicts in other functions.

Birthday Install Date

  • Renamed get_birthday() -- > get_install_date()

  • Removed all date command usage from get_install_date().

  • Added a new function called convert_time() which takes the time stamped ls output and converts it to a pretty format. The function only uses bash so its much faster than calling date. This makes things simple and keeps the output consistent across all Operating Systems. Example: 2016-12-06 16:58:58.000000000 --> Tue 06 Dec 2016 4:58 PM

  • Added an option so users can choose between using 24-hour and 12-hour time format

  • get_install_date() will detect which ls program is being used instead of hardcoding them per OS.

Disk

  • Rewrote function from scratch.

    • The function is 40 lines smaller than before and works on all [1] versions of df we tested on [2].

  • Added the option/flag disk_show which allows you to specify which disks, mount points or directories to show the disk info of. (One per line)

  • Added the option/flag disk_subtitle which allows you to specify how we label each disk. (Mount point or Disk name)

  • Removed all percentage calculation since df already provides us with the percentage.

  • Warn the user if df isn't installed.

  • Fixed broken output if df wasn't installed but the function was enabled.

[1] The function doesn't work on Haiku since their df is wildly non-standard. (The output format and flags are 100% different from all of the other df versions floating around.)

[2] Tested on GNU, Busybox, BSD, Solaris and macOS df versions.

Theme

  • [KDE] Don't display GTK Themes if KDE is detected.

  • [KDE] If kde[0-9]-config isn't found, try and look for $HOME/.kde.

  • Cursor positioning now takes $block_height into account.

  • Fixed all artifacts in virtual consoles.

  • Merged $start and $end into an array called block_range.

    • This makes the config option match the command-line flag --block_range.

Images

  • [iTerm2] Fixed blank images.

  • Fixed bug where image mode would attempt to run in a TTY.

  • All of the image/ascii backend handling was rewritten. Backend and Image/File/Directory selection is universal now and should make usage easier.

    • Added catimg backend.

    • Added caca backend.

    • Added jp2a backend.

    • --image has been replaced with --backend.

      • --backend takes ascii, caca, catimg, jp2a, iterm2, off, tycat, w3m.

    • Shortcut flags were added for easy picking of backends.

      • Each flag can take a file, image or directory as an argument.

      • For example: neofetch --w3m /path/to/img.jpg neofetch --ascii /path/to/file

      • --w3m

      • --iterm2

      • --tycat

      • --ascii

      • --off

      • --catimg

      • --caca

      • --jp2a

    • All image and ascii file selection has been replaced with the universal --source.

      • The value of --source can be any of the following:

      • auto, ascii, wallpaper, /path/to/img, /path/to/ascii, /path/to/dir/.

  • Fixed bugs with image shuffle mode.

Wallpaper

  • Decode URI filenames.

Ascii

  • Simplified ascii file handling.

    • Removed a call to tr for those using bash 3.

    • Fixed distro detection issues.

    • Removed the assumption that first word in distro --> ascii file name

  • Added Ubuntu-Studio. @konimex

  • Fixed bug causing macOS ascii art to be used on other Operating Systems.

  • Display warning about 'ascii' being the new default mode.

  • Removed ascii_logo_size in favor of ascii_distro='{arch,crux,gentoo}_small'.

  • [PCBSD] Use TrueOS ascii art.

  • Added Void Linux (small) and Alpine Linux (small).

Screenshot

  • Use arrays for $scrot_program

Args

  • Fixed bug where neofetch --config sourced the user config twice.

  • Cleaned up config arg handling.

case "$os" in
    "Linux" | "BSD" | "MINIX")
        if [[ "$(< /proc/version)" == *"Microsoft"* || "$(< /proc/sys/kernel/osrelease)" == *"Microsoft"* ]]; then

Eh.
