Homebrew for OSX users brew install sc-im Ubuntu with XLSX import & export See this wiki page. Other distros / OS Please check wiki pages Configuration The scimrc file can be used to configure sc-im. The file should be placed in the ~/.config/sc-im directory. Here is an example ~/.config/sc-im/scimrc : set autocalc set numeric set numeric_decimal=0 set overlap set xlsx_readformulas To keep command and insert-mode history only for the current session, add set nohistory_file at the start of scimrc. This disables loading and saving sc-iminfo without deleting an existing history file. History persistence is enabled by default. Other configuration variables are listed in the help file.
