CHANGES in bvi 1.2.0

• Configuration with GNU autoconfig
• New :set options:
  • :set columns=n
    You can set the number of columns on the screen to an arbitrary value. This might be useful if you edit a file with a fixed record length.
    Default: max number of columns, divisible by four.
    Abbreviation: :set cm=n
  • :set memmove enables the new commands to insert or delete bytes.
    Per default this commands are disabled, because e.g. in executable files you must not move bytes.
    Default: :set nomemmove
    Abbreviation: :set mm - :set nomm
  • The listing for :set all is now in alphabetical order.
• New insert and delete commands:
  • a inserts after cursor position
  • i inserts on cursor position
  • x deletes byte under cursor
  • X deletes byte before cursor
  • d delete command with modifiers:
    • dSPACE deletes byte under cursor
    • dfC deletes from current position to next character C
    • d/xyz deletes from current position to first matching pattern xyz
    • d$ deletes from current position to EOF
    • d'a deletes from current positions to mark a
    • dnG deletes from current position to byte with (decimal) address n
• New syntax for p (put) command:
  In previous versions of bvi the p command did an overwriting "put". Now the bytes are inserted.
• New command o (overwrite):
  This is an overwriting "put" command. It is the only command in bvi that uses a command key in a complete different way than in vi (o opens a new line in vi).
• New syntax for y (yank) command:
  • ySPACE yanks byte under cursor
  • yfC yanks from current position to next character C
  • y/xyz yanks from current position to first matching pattern xyz
  • y$ yanks from current position to EOF
  • y'a yanks from current position to mark a
  • ynG yanks from current position to byte with (decimal) address n
• New ex (colon) commands:
  • :a(ppend) a(scii)|b(binary)|d(ecimal)|h(exadecimal)|o(ctal)
  • :c(hange) a(scii)|b(binary)|d(ecimal)|h(exadecimal)|o(ctal)
  • :i(nsert) a(scii)|b(binary)|d(ecimal)|h(exadecimal)|o(ctal)
    The three commands above are used to append or change or insert bytes in the selected representation until you type a line containing only a dot, e.g. insert bytes in binary mode:

    	:i b
    	0 010 110 1110010 10 100
    	1 1001 1001 0 0
    	.
    	

    Pressing the RETURN key does not insert a newline - character into the file. If you use :i a (insert ascii) you can use the special characters \n, \r, \t and \0.
  • :d(elete)
  • :g(lobal) does a global search with printing found items
  • :ma(rk)
  • :pu(t) puts yanked bytes into the file
  • :o(verwrite) is an overwriting ":put"
  • :y(ank)
• :f newname - bug fixed
• new command line option -f script
• CTRL - C aborts some commands, e.g. search commands
• CR moves cursor to 1st column of next screen line
• Local settings according to the environment variable LANG will be evaluated (see setlocal(3)).
