When viewing the Code, if the code is very lengthy, especially in the C/C ++ series, The code structure is hard to clarify, mainly due to the matching of comments and parentheses, Although % can be used to check where the other half of the matching symbols are, it is hard to understand if the code between the two symbols exceeds one page or even several pages. Therefore, we can use the folding feature provided by VIM to simplify the analysis. The Vim I use is a built-in version of rh9. Fold mode: Vim provides the folding mode in Step 6.    Manual    Manual folding    Indent   More indentation indicates a higher level of collapse    Expr    Use expressions to define collapse    Syntax   Use syntax highlighting to define collapse    Diff     Collapse Unchanged text    Marker   Fold the mark in the text You can use the 'foldmethod' option to set the foldmethod: Set OFDM = *****. Note that each folding method is incompatible, that is, you cannot use expr or marker. Currently, I usually use more indent instances. Use the: Set OFDM = indent command to set the marker folding mode. Add settings in the. vimrc file to enable the folding mode for each opened VI. For example, add set OFDM = syntax. 2. Fold opening and collapse After the folding method is selected, we can implement the folding we need for some code. If the indent method is used, VIM automatically folds the middle part of the braces, and we can directly use these ready-made folding results. The folding code corresponding to indent is: ZC Fold ZC  Collapse all nested folding points within the specified range Zo Expand and collapse Zo  Expand All nested folding points in the specified range [Z To the start of the current fold. ] Z To the end of the currently opened fold. ZJ Move down. To the start of the next fold. The closed folding is also included. ZK Move up to the end of the previous fold. The closed folding is also included. Enter the preceding command in braces for use. When using the marker method, you need to use a tag to identify code folding. The default value of the system is {And}. Do not change it :) You can use the following command to create and delete a fold: ZF Create a fold, for example, in the marker mode:       Zf56g: Creates code folding from the current row to 56 rows;       10zf, 10zf +, or zf10 labels, create code folding from the current row to the last 10 lines.       10zf-or zf10 labels, create code folding from the current row to the previous 10 lines.       At ZF %, create the matching brackets (), {}, [], etc.) from the current row ). ZD Delete the folding of the cursor. Valid only when 'foldmethod' is set to "Manual" or "marker. ZD  Click Delete to collapse the cursor.    Valid only when 'foldmethod' is set to "Manual" or "marker. Ze  Remove all folds in the (eliminate) window.    Valid only when 'foldmethod' is set to "Manual" or "marker. Source: Http://hi.baidu.com/flost_li/blog/item/aede68afcc7955c87dd92af7. Html
