![]() #Vi text editor codeThis is the part many people don't seem to get.Īrrow keys don't work in Insert mode and type "garbage" when they are pressed because they are literally telling vi to "insert" the control code for your arrow key, so it does: ^B. You type "new" text in Insert mode, while almost all movement and text editing is done in Command mode. If you use vim|n/vi as intended then the hjkl and/or arrow keys -in Command mode- will still be your last resort for getting around in a file. Otherwise you might as well be using MS Win Notepad. It is faster and allows you to use the actual power of vim|n/vi. Movement is meant to be done in Command mode. You should not be moving the cursor around in Insert mode, arrrow keys or otherwise, 1980's or not. Generally your basic vim skills of ^[ibla foo bar^[:wq! will transfer enough to "real" vi if you need to support a real UNIX such as AIX, HP-UX, or Solaris.īut if you rely on arrow keys to "move around" while in Insert mode then you are going to be in for a rough time. If you don't know, ^[ is the code for the "ESCAPE" key. The vim Devs know about this bug but do not think it is worth fixing.īetter not try that in vim on a Production box. One append of 50,000 repetitions can lock a session up for almost an hour in any vim version I've ever tested.Ī 2,000,000 append of the same data in nvi takes less than 5 seconds. "improved" in vim, the non-classic behavior of the "BACKSPACE" key, and how slow vim-tiny is compared to n/vi at times. The biggest thing I notice is how undo / re-do has been brok. The reality is most people use very little of "real" vi's capabilities and even less of vim's or nvi's. To add to what said, it is easier to read it straight from, if you don't wish to test things yourself. And you can fix most of that by tuning you configuration D Vim (while certainly being IMproved as it claims) is also a bloated, weird and inconsistent mixture of a broken vi and a modeless editor. Sure it's convenient at first that you can for example move with cursor keys in insert mode, but it also has some really weird unwanted side-effects (for example the. Unfortunately vim breaks the vi philosophy by mixing the editor modes and introducing a vast number of useless and redundant functions. Vim certainly has a lot that speaks for it. It has multiple ways of numbering lines, which is really convenient. In addition to syntax hilighting (when compiled with a support for it) it does automatic conversions of charactersets, line-endings and such. Neither of them are perfect, but they're still better than anything else is out there. There is indeed quite a big difference between them. Refer below sources which are few of good places to start finding out more. Vim can be scripted with vimscript, or with an external scripting language (e.g.Vim includes support for plugins, and finer control over config and startup files.Vim includes a built in diff for comparing files (vimdiff). #Vi text editor archiveVim can edit files inside a compressed archive (gzip, zip, tar, etc).Vim allows the screen to be split for editing multiple files.Vim can be used to edit files using network protocols like SSH and HTTP.Vim includes support (syntax highlighting, code folding, etc) for several popular programming languages (C/C++, Python, Perl, shell, etc).Vim has been ported to a much wider range of OS's than vi.Here are a some of the extended vim features: Therefore, everything that is in vi is available in vim. Functionally, vim is almost a proper superset of vi. ![]()
