Uninstalling letsencrypt – Let’s Encrypt Community Support

If you have the environment variable XDG_DATA_HOME set, the installation is located at $XDG_DATA_HOME/letsencrypt. Otherwise, it is located at ~/.local/share/letsencrypt. You can simply delete this directory. You can also delete configuration, work, and log directories which by default are stored at /etc/letsencrypt, /var/lib/letsencrypt, and /var/log/letsencrypt respectively. The directory where you cloned our git repo can also be deleted.

Let’s Encrypt also installs some OS dependencies and how you remove these would be very OS specific. To see what dependencies were installed, take a look at the files in the bootstrap folder at the root of our git repo (link). Take a look at the shell script for your OS to see what packages are required. You can uninstall these packages through the normal means of your OS, but make sure they aren’t required by any other programs on your system.

Export Compact SVG with Sketch

Bohemian Coding – Preferences.

Used to tell Sketch to export compact SVG files. We add some metadata to exported SVG files, to make it easier to re-import them in Sketch. However, if you are sure you won’t import them, you can disable the saving of metadata by running this into your Terminal.app:

$ defaults write com.bohemiancoding.sketch3 exportCompactSVG -bool yes

When this is set to YES, Sketch will not use the name of the layer for the id field of the layer in SVG export:

$ defaults write com.bohemiancoding.sketch3 svgExportSkipAssignIdToLayerName -bool yes
