5.0 - What's online at the vi archives? There is a FAQ posted frequently which gives a list of all the files that are online at the vi archive. It also gives a list of addresses which mirror the vi archive. The main address is ftp://alf.uib.no/pub/vi, but it is archived at many, many sites. The vi-archive faq lists all of them. Please check that faq before ftping to it, as there is almost definitely a closer and therefore faster site to you than the one in Norway. A few mirrors are: <ftp://ftp.uu.net/pub/text-processing/vi>. <ftp://ftp.cc.monash.edu.au/pub/vi> The site has many, many files on vi, including a few clones. It also has the UCB distribution of vi, and lots of useful macros. Check it out. 6.0 - Silly vi tricks, and silly macros This section is for silly vi tricks, and silly macros. Actually, any interesting vi tricks and macros are acceptable, as long as they are not too lengthy. I will add any that are suggested to me that I think are reasonable. 6.1 - Silly vi tricks Note: Also check out the Silly macros down below. Many macros and tricks are interchangeable. xp This will delete the character under the cursor, and put it afterwards. In other words, it swaps the location of two characters. ddp Similar to xp, but swapping lines. yyp duplicate a line uu Undo and redo last change. (This will take you to the last modification to the file without changing anything.) You can also use this to compare the changes to a line. Make the changes to the line, press U to undo the changes to the current line, and then press u to toggle between the two versions. :g/.*/m0 This will reverse the order of the lines in the current file. m0 is the ex command to move the line to line 0. :v/./d or :g/^$/d Removes all blank lines. :g/^[ <ctrl-v><tab>]*$/d Removes all lines that only have whitespace. :v/./$s/$/<ctrl-v><enter>./|'';/./-1j|$d Replaces multiple blank lines with just one blank line. 6.2 - Silly macros Note: <ctrl-x> means hold down control, and hit x. Swap character and one vertically above: map * kxjphxkP Fold a line that's too long map g $80<ctrl-v><ctrl-v>|F r<ctrl-v><enter> Change case on most words map v ywmno<ctrl-v><esc>P:s/./\~/g<ctrl-v><enter>0"nDdd`n@n Put `and' around the current word map *` i`<ctrl-v><esc>ea'<ctrl-v><esc> Put 'and' around the current word map *' i'<ctrl-v><esc>ea'<ctrl-v><esc> Put "and" around the current word map *" i"<ctrl-v><esc>ea"<ctrl-v><esc> Put `and' around the current word map! `` <ctrl-v><esc>bi`<ctrl-v><esc>ea' Split a line at the cursor, and put a > at the beginning of the next line. (For quoting Usenet, etc). I had some trouble with my old version of this under some versions, so I've redone it, and I think that it should work. map g may0O<ctrl-v><esc>P`ao<ctrl-v><esc>P:s/./ /g<ctrl-v><enter>0i><ctrl-v><esc>$mb`ay$`bP'add Insert one character map g i$<ctrl-v><esc>r Format a paragraph without the fmt program.

In addition, the source command (so), abbreviations (ab), and macros may be used. There may not be any blank lines in your .exrc. A " in the first column may be used to tell vi that what follows is a comment. 8.1 - Sample .exrc file This .exrc file is a real one. Mine. Because of that, it doesn't set as many options as one might wish it did to get a good idea of what may be used. However, it should get the basic idea down, and it is quite straightforward.

These bugs are bugs in the original vi, not necessarily in any of the different clones. Macros for _ do not always work properly. #~ does not work under AIX The left and right hand side of macro definitions can be at most 100 characters. If they're more than 100 characters it doesn't give a decent error message -- it either says that it is too dangerous to map or that the rhs is missing. 10.0 - Glossary of terms This glossary will be updated as people suggest terms that they do not understand. Please let me know if you have any suggestions. command mode Command mode is the mode within vi where the user gives commands to vi. (Including cursor movement commands, editing commands, etc.) ed A non-visual editor under Unix. <Esc> The escape key. A key on a keyboard normally marked by escape. Sometimes ^[ will work in its place. If there is no escape key, sometimes the Meta key will work. ex An editor under Unix, all commands preceded with : are passed to it. insert mode Insert mode is the mode within vi where text is inserted into the document. macro A macro is a shortcut key combination. For example, a macro allows one to hit one letter and have it execute a few different commands. open mode Open mode is the mode that vi will start in if it cannot determine your terminal type, or if it believes you have a hardware or glass-tube terminal. regular expressions (RegEx) (RE) Regular expressions, commonly known as "RegEx" or "REs" are a set of key combinations that are meant to allow people to have a large variety of control over what they are searching for. RegEx is used a lot under Unix, and is common between many programs. sed Stream editor. An editor that has no interface. All commands are given from the command line. vi The editor to which this FAQ is dedicated. 11.0 - Bibliography of Books that cover vi VI QUICK REFERENCE/HELP CARDS Specialized System Consultants, Inc.
