Coding In Vim

Vim is a highly customizable command line text editor available on all platforms. It works well as an integrated development environment (IDE) and has many powerful features like macros, plugins, and modes for different editing tasks. The vimrc file allows customizing Vim preferences and is loaded automatically. Common plugins help with tasks like searching files, viewing directories, debugging code, and checking syntax. Vimdiff can be used to diff multiple files and leverage scripts to diff changed repository files. While Vim has a steep learning curve, its power and customizability make it a valuable editor to learn.

Tab Current Line Contents Right: <SHIFT>> Tab Current Line Contents Left: <SHIFT>< Auto Format: = Search For Next Word Under Cursor: <SHIFT>* Start Recording Macro: q<KEY> Stop Recording Macro: <ESC>q Play Macro: <SHIFT>@<KEY>
- 6. Auto Text Completion: <CONTROL>p Select Line(s): <SHIFT><RIGHT CLICK HOLD AND DRAG> Copy Selection To Clipboard: <CONTROL><SHIFT> c OR <LEFT CLICK> Paste From Clipboard: <CONTROL><SHIFT>p OR <LEFT CLICK> Insert Mode <ESC> i ● Direct keyboard edits Select Mode ● Windows like operations

- 12. Plugins Vundle - Plugin manager Control P - Recursively search for files using regex NerdTree - Directory listing viewer vDebug - Code debugging using xDebug cTags - Drill into code tList - Source code structure Syntastic - Syntax checker There's probably a plugin for that!
- 13. VIMDIFF vimdiff <file1> <file2> ● For diffing 2 or more files ● Comes with vim installation ● Leverage a bash script to vimdiff changed repo files. (see my guthub account for an example)
- 14. Painful Quirks and Gotchas! ● “<CONTROL> S” Accepts key strokes but quits echoing. Recover: <CONTROL> Q ● Not all terminal emulators are created equal (putty, bash). Expected key mappings may be overridden but can be changed in the terminal preferences. ● Steep Learning Curve
