Install cheat.sh in the standalone mode.
After the installation, cheat.sh can be used locally, without accessing
the public cheat.sh service, or it can be used in the server mode,
where the newly installed server could be accessed by external clients
in the same fashion as the public cheat.sh server.
During the installation, cheat.sh code as well as the cheat.sh upstream
cheat sheets repositories will be fetched.
It takes approximately 1G of the disk space.
Default installation location: ~/.cheat.sh/
It can be overridden by a command line parameter to this script:
${0##*/} --standalone-install DIR
See cheat.sh/:standalone or https://github.com/chubin/cheat.sh/README.md
for more information:
cht.sh :standalone
curl cheat.sh/:standalone
After the installation is finished, the cht.sh shell client is switched
to the auto mode, where it uses the local cheat.sh installation if possible.
You can switch the mode with the --mode switch:
cht.sh --mode lite # use https://cheat.sh/ only
cht.sh --mode auto # use local installation
For intallation and standalone usage, you need \`git\`, \`python\`,
and \`virtualenv\` to be installed locally.

{ / / } Now you can use cheat.sh in the standalone mode,
{ /_/ } or you can start your own cheat.sh server.
Now the cht.sh shell client is switched to the auto mode, where it uses
the local cheat.sh installation if possible.
You can switch the mode with the --mode switch:
cht.sh --mode lite # use https://cheat.sh/ only
cht.sh --mode auto # use local installation
You can add your own cheat sheets repository (config is in \`etc/config.yaml\`),
or create new cheat sheets adapters (in \`lib/adapters\`).
To update local copies of cheat sheets repositores on a regular basis,
add the following line to your user crontab (crontab -e):
10 * * * * $installdir/ve/bin/python $installdir/lib/fetch.py update-all
All cheat sheets will be automatically actualized each hour.
If you are running a server reachable from the Internet, it can be instantly
notified via a HTTP request about any cheat sheets changes. For that, please
open an issue on the cheat.sh project repository [github.com/chubin/cheat.sh]
with the ENTRY-POINT from the URL https://ENTRY-POINT/:actualize specified
