DESCRIPTION
 SpaceFM is a multi-panel tabbed file and desktop manager for Linux with
 built-in VFS, udev- or HAL-based device manager, customisable menu system,
 and bash integration. SpaceFM aims to provide a stable, capable file
 manager with significant customisation capabilities.
PACKAGES
 SpaceFM is included in most distro repositories. To find packages, forum
 threads, and other info for your distro, see:
 https://github.com/IgnorantGuru/spacefm/wiki/Distros
 For other distros, or to build with custom options, see INSTALLER below.
INSTALLER
 The easiest way to download and build SpaceFM is to use the net installer,
 which automates the instructions in this README. To download the installer:
 wget https://raw.github.com/IgnorantGuru/spacefm/next/spacefm-installer
 # OR using curl:
 curl -L -o spacefm-installer \
 https://raw.github.com/IgnorantGuru/spacefm/next/spacefm-installer
 To run the installer (MUST be run in a terminal):
 bash spacefm-installer
 Most users can press Enter to accept default values at both prompts.
 The installer will display dependencies for your chosen build. If
 any dependencies are missing, examine the error, install missing packages,
 and try again. See DEPENDENCIES below for reference.
 If you have already downloaded the source, the installer can be run from
 within the source directory to automatically build and install:
 ./spacefm-installer
 When SpaceFM is installed, the installer is also installed to /usr/bin.
 For automated options, run: spacefm-installer --help
 To reinstall or upgrade, just run the installer again. For example, to
 upgrade to the latest rolling release, just run:
 spacefm-installer --version=next --prefix=/usr
 To uninstall: spacefm-installer --uninstall
DEPENDENCIES
 Install required build dependencies (below are Debian package names -
 packages names on your distro may vary but should be similar):
 autotools-dev bash build-essential intltool pkg-config fakeroot
 shared-mime-info desktop-file-utils libc6 libcairo2 libglib2.0-0
 libglib2.0-dev libpango1.0-0 libx11-6 libx11-dev libudev1
 libudev-dev libffmpegthumbnailer-dev
 Also, if using GTK2: libgtk2.0-0 (>=2.18) libgtk2.0-dev libgtk2.0-bin
 OR, if using GTK3: libgtk-3-0 libgtk-3-dev libgtk-3-bin
 Also, if you want to use startup notification: libstartup-notification0-dev
 For optional dbus support: dbus libdbus-1-3 libdbus-1-dev
 RECOMMENDED: udevil|pmount|udisks gksu|kdesu|ktsuss|lxqt-sudo eject lsof
 wget
 For additional mounting support: fuseiso curlftpfs jmtpfs gphotofs ifuse
 IMPORTANT: SpaceFM is highly integrated with bash and uses features of
 bash v4. Attempting to substitute another shell for bash WILL cause
 feature breakage, even if not immediately apparent. Install genuine bash.
 configure will report anything missing when you run it as shown below.
DOWNLOAD
 SpaceFM is distributed via Github:
 https://github.com/IgnorantGuru/spacefm/releases
 First, make a temporary directory and enter it:
 mkdir /tmp/spacefm-build
 cd /tmp/spacefm-build
 To download a branch, particular version, or under-development commit, use:
 wget -O spacefm.tar.gz https://github.com/IgnorantGuru/spacefm/archive/next.tar.gz
 The above example downloads the 'next' branch, which is SpaceFM's rolling
 release. You can also substitute 'master' (stable release), a version
 number (eg '1.0.4'), or a commit (eg 1709b809) for 'next' in the above URL.
 Then, extract the archive, and enter the source directory:
 tar xzf spacefm.tar.gz && cd spacefm-*
 ALTERNATIVELY, instead of downloading the tarball with wget above, you can
 use git to clone the SpaceFM source repo, check signatures, and download
 upgrades. See the USING GIT section further below.
INSTALL
 Use these commands to build and install:
 ./configure --prefix=/usr
 make -s
 sudo make install
 sudo update-mime-database /usr/share/mime > /dev/null
 sudo update-desktop-database -q
 sudo gtk-update-icon-cache -q -t -f /usr/share/icons/hicolor
 sudo gtk-update-icon-cache -q -t -f /usr/share/icons/Faenza
 # Remove Temporary Files
 cd / && rm -rf /tmp/spacefm-build
 If configure reports missing dependencies, install them and run configure
 again before proceeding to make.
 configure options for alternate builds:
 --with-gtk3
 By default, configure will use GTK2 if installed. To force use of
 GTK3, add --with-gtk3.
 BE SURE to use a GTK3 theme which supports your CURRENT version of GTK3
 (no theme warnings should appear when spacefm is run in a terminal),
 or use Adwaita.
 PACKAGERS: Due to other desktop components, some users may require or
 prefer GTK2. Please consider providing both spacefm-gtk2 and
 spacefm-gtk3 packages for your users.
 --disable-video-thumbnails
 Remove support for video thumbnails. Omit libffmpegthumbnailer.
 --enable-hal
 Use HAL instead of udev. Device manager functions are extremely
 limited. Use of this build is only recommended if udev or eudev is not
 available. SpaceFM HAL support is no longer actively developed, yet
 please report any build problems.
 Instead of libudev1 and libudev-dev, install:
 hal libhal-dev libhal-storage-dev libhal-storage1 libhal1
 libdbus-glib-1-2 libdbus-glib-1-dev dbus libdbus-1-3 libdbus-1-dev
 --sysconfdir=/etc
 Set the correct location of /etc on your system for installing
 /etc/spacefm/spacefm.conf.
 For additional configure options, see: ./configure --help
 To run root commands, SpaceFM supports gksu, gksudo, gnomesu, kdesu,
 kdesudo, ktsuss, lxqt-sudo, xdg-su, su-to-root, su, and sudo. To configure
 an additional terminal or graphical su program see
 /etc/spacefm/spacefm.conf. Or, to build with an additional graphical su
 program ('/usr/bin/mysu' in this example), add:
 --with-preferable-sudo=/usr/bin/mysu
 Note: When using older distros, enabling kernel polling may be required. If
 you insert a CD and SpaceFM still says 'no media', please see the ENABLE
 KERNEL POLLING section further below.
BUILD DEBUG
 If SpaceFM crashes or hangs on your system, you can help to correct this
 problem by reporting it, including a full backtrace.
 The easiest way to install a debug-compatible version of SpaceFM is using
 the installer. See INSTALLER section above. At the install options
 prompt, enter 1 for Debug. Or run: spacefm-installer --version=next 1
 OR, to manually build for debugging:
 1) Install build dependencies for your build (see DEPENDENCIES above).
 2) Install the 'gdb' GNU Debugger, and debugging library symbols. For
 example on Debian (packages on other distros should have similar names):
 libc6-dbg libglib2.0-0-dbg libgtk2.0-0-dbg|libgtk-3-0-dbg librsvg2-dbg gdb
 3) Follow the DOWNLOAD and INSTALL instructions above, substituting this
 configure command (add any other desired configure options):
 CFLAGS='-ggdb3' STRIP='!strip' ./configure --prefix=/usr
 4) After completing the install, run spacefm with the debugger:
 gdb spacefm
 In gdb, enter 'run' at the prompt. Or, to make gdb halt on any
 warnings, use 'run --g-fatal-warnings'.
 SpaceFM will start. When the crash occurs, gdb will freeze SpaceFM.
 Or if SpaceFM hangs, press Ctrl-C in gdb to interrupt it, or in another
 terminal run: killall -s KILL spacefm
 5) In gdb enter: thread apply all bt full
 Provide the output with your detailed bug report at
 https://github.com/IgnorantGuru/spacefm/issues
 NOTE: When SpaceFM is built this way, it may run more slowly and use more
 memory. Once you are done debugging, be sure to install a normal
 (optimized) build.
CREATE DEBIAN PACKAGE
 It's easy to create a binary deb package of SpaceFM on your Debian-based
 distro. Please see the file distros/debian/README-DEBIAN. Also note that
 there are SpaceFM packages in the official Debian repos and elsewhere:
 https://github.com/IgnorantGuru/spacefm/wiki/Debian
UNINSTALL
 If you installed from a package, use your package manager to remove
 SpaceFM. Or, use the installer to uninstall:
 spacefm-installer --uninstall
 Otherwise, run these commands AS ROOT:
 rm /usr/bin/spacefm /usr/bin/spacefm-auth /usr/bin/spacefm-installer
 rm -r /usr/share/spacefm # this may remove SpaceFM plugins
 rm /usr/share/pixmaps/spacefm.png
 rm /usr/share/pixmaps/spacefm-*.png
 rm /usr/share/icons/hicolor/*/apps/spacefm.png
 rm /usr/share/icons/hicolor/*/apps/spacefm-*.png
 rm /usr/share/icons/Faenza/apps/48/spacefm.png
 rm /usr/share/icons/Faenza/apps/48/spacefm-*.png
 rm /usr/share/*/LC_MESSAGES/spacefm.mo
 rm /usr/share/applications/spacefm*.desktop
 rm /usr/share/mime/packages/spacefm-mime.xml
 update-mime-database /usr/share/mime > /dev/null
 update-desktop-database -q
 gtk-update-icon-cache -q -t -f /usr/share/icons/hicolor
USING GIT
 Instead of downloading a tarball to install SpaceFM, you can download some
 or all of the source repo using git. See a tutorial for complete git
 instructions, but a few examples are provided below.
 To download just the source dir of a given branch, version, or commit, run:
 git clone --depth 1 -b next git://github.com/IgnorantGuru/spacefm.git spacefm
 cd spacefm
 You can substitute any branch or version (eg 1.0.4) for 'next' in the above
 command. To build and install, see INSTALL above, or run:
 ./spacefm-installer
 To pull in the latest changes to the next branch, run:
 git pull origin next
 Then you can proceed to INSTALL instructions to install the upgrade, or
 run: ./spacefm-installer
 Although git already includes strong integrity protection, SpaceFM release
 tags are also signed with IgnorantGuru's GPG key 0x01937621 (Key
 fingerprint = 7977 070A 723C 6CCB 696C 0B02 27A5 AC5A 0193 7621).
 To verify the GPG signature on a release (1.0.4 in this example), run:
 git tag -v 1.0.4
 To download the full SpaceFM source repo, with all branches and history:
 git clone git://github.com/IgnorantGuru/spacefm.git spacefm
 cd spacefm
 To find the sources for a particular branch (eg next or master), version,
 or commit (in this example, version 1.0.4), run:
 git checkout 1.0.4
 Then you can proceed to INSTALL instructions or run spacefm-installer.
 To create a tar.xz archive of the sources for version 1.0.4:
 git archive 1.0.4 --prefix=spacefm-1.0.4/ | xz > spacefm-1.0.4.tar.xz
ENABLE KERNEL POLLING
 Kernel polling, which allows for device and media change detection, is a
 newer feature of the Linux kernel and udev, so some distros don't yet have
 it enabled by default, but most already do. If you insert a CD and SpaceFM
 still says 'no media', this is a symptom that kernel polling is not
 enabled.
 To use kernel polling, your Linux kernel may need to be 2.6.38 or newer,
 and udev may need to be version 173 or newer.
 TO DETERMINE IF KERNEL POLLING IS ENABLED:
 cat /sys/module/block/parameters/events_dfl_poll_msecs
 cat /sys/block/sr0/events_poll_msecs
 If you get 0 or -1 from both of those commands, kernel polling may be
 disabled.
 TO ENABLE KERNEL POLLING PERMANENTLY (survives a reboot), add the
 following command to your /etc/rc.local file (anywhere before the
 'exit' line in that file):
 echo 2000 > /sys/module/block/parameters/events_dfl_poll_msecs
 Any number between 2000 and 5000 (milliseconds) should be reasonable -
 the higher 5000 means poll every 5 seconds, which is less overhead but
 a little slower.
 OR pass this option to the kernel boot command line in grub:
 block.events_dfl_poll_msecs=2000
 OR add a udev rule to enable kernel polling on removable devices:
 echo 'ACTION=="add", ATTR{removable}=="1", \
 ATTR{events_poll_msecs}=="-1", ATTR{events_poll_msecs}="2000"' \
 > /etc/udev/rules.d/61-removable-storage-polling.rules
 A reboot will be required for the above changes to take effect, or...
 TO ENABLE KERNEL POLLING TEMPORARILY AND IMMEDIATELY, enable common
 polling for the block module:
 sudo bash -c 'echo 2000 > /sys/module/block/parameters/events_dfl_poll_msecs'
 OR you can enable polling just for a single device like this (/dev/sr0
 in this example):
 sudo bash -c 'echo 2000 > /sys/block/sr0/events_poll_msecs'
 This change should be immediate - media will be detected. However, the
 above change will be lost when you reboot.

RELEASE
 For developers: The 'release' script in the SpaceFM source dir is used by
 SpaceFM developers (or forks) to perform a release.
 To use this script, complete changes to the next branch (they don't have to
 be commited), then run: ./release
 Note the manual workflow items listed by the script before proceeding.
 The script will interactively perform a release of SpaceFM by increasing
 the version number, preparing the source dir for distribution, commiting
 the next branch, merging to master, signing the release tag, pushing
 master, starting the next version, and pushing next. You must have
 permission to push to git's origin. It also optionally pulls the wiki, and
 pushes gh-pages, if present.
 When the script is finished, master branch will contain the new release,
 next branch will be prepared for the next version, and Github will show the
 release tag in Releases.
