In this video, we reformat our file by removing our current indentation, then auto-format it as a perl script We then change the foldmethod to indent and see: zo - opens a single fold zc - closes a single fold zO - opens all folds in a single nested fold zC - closes all folds in a single nested fold zr - reduce all folds one level (same as zo but for all folds) zR - reduce all folds all the way (same as zO for all folds) zm - fold up (minus) a nested fold level for all folds (same as zc for all folds) zM - fold up (minus) all nested folds levels for all folds (same a zC for all folds) Foldmethods are: Manual – folds must be defined by entering commands (like zf) indent - creates a fold for each indent Syntax – create a fold by the syntax of a programming language Expr – folds are created by a user-defined expression (like a regex / regular expression) Marker – Create folds for a start and end characters you define Diff – used to fold unchanged text when viewing differences (automatically set in diff mode) See the complete Vim playlist at: https://www.youtube.com/watch?v=1lzXr-MztOU See the complete Vim playlist in a single video at: https://www.youtube.com/watch?v=3G6kAEvbv2A Website link: https://thefrugalcomputerguy.com/linux/seriespg.php?ser=10002
