List of known bugs:
|
|
|
|
+ Large numbers of matches (e.g. %, g or v commands), with the
|
|
ignorecase option set, triggers a memory corruption bug in the
|
|
regex routines.
|
|
|
|
+ Autoindent doesn't work in the ex editor.
|
|
|
|
+ ^C isn't passed to the shell in the script windows as an interrupt
|
|
character.
|
|
|
|
+ The command ":ab foo^J bar" prints a usage message -- non-word
|
|
characters should be quoted in the underlying terminal engine
|
|
so that the upper-level knows they're quoted and doesn't use them
|
|
as delimiters. (Note, this isn't historical practice, vi didn't
|
|
permit escaping of ^J in this type of command.)
|
|
|
|
+ The options edcompatible, hardtabs*, lisp*, optimize*, redraw*,
|
|
and slowopen* are recognized, but not implemented. Options with
|
|
an asterisk are unlikely to ever be implemented, so if you want
|
|
them you might want to say something! I will implement lisp if
|
|
anyone ever documents how it really worked.
|
|
|
|
+ Screen repainting over slow lines, for some screen changes, is not
|
|
as good as the historic vi's.
|
|
|
|
+ If an error results during input in ex, it is not displayed until
|
|
after input mode is exited.
|
|
|
|
+ If the ex append command is used from vi, the input command buffer
|
|
is overwritten by the ex_append function, causing random errors.
|
|
|
|
+ Colon commands longer than a single line cause the display to be
|
|
incorrect.
|
|
|
|
+ When switching files in a small screen (O_WINDOW) with :e, the status
|
|
message isn't displayed.
|
|
|
|
+ The usages of S_{REDRAW,REFORMAT,REFRESH,RENUMBER,RESIZE} are
|
|
inconsistent, and should be reviewed. In particular, S_REFRESH
|
|
in any screen redraws all screens.
|
|
|
|
+ Historic vi permitted :g/xxx/vi, i.e. you could execute ex/vi as
|
|
global commands. Need to review all of the old commands to verify
|
|
which ones could/could not be used as global commands.
|
|
|
|
+ If you run out of space in the recovery directory, the recovery
|
|
file is left in place.
