- (These are sorted by how irritating they are. The worst bugs are at the top.)
-
- - It is impossible to edit or view the same file more than once. It is
- also impossible to invoke Elvis twice with no arguments when in the same
- directory. This is caused by the way the temp file is named based on ".",
- see function tmpstart() in tmp.c.
-
- - Inserting characters to make a line longer than BLKSIZE-1 (including the
- newline) causes a crash. BLKSIZE is 1024 by default. The shift-J and :join
- commands protect against this, but something like "9999a!<Esc>" will make
- Elvis misbehave. Also, huge files (more than about 500k) cannot be edited.
-
- - autoindent is confusingly different from vi when editing typical
- indented C code - e.g. after <ESC>o<ESC>xxxxxxxxxxi (x's to column 1)
- the last i indents again.
-
- ^U backspaces to the beginning of the line, but it should only backspace to
- the start of auto-indent. (A second ^U could reasonably delete the indent
- too)
-
- - The :@ and :source commands share a single buffer. This means that they
- can't call each other. You can't run :source from within your .exrc file
- either, for the same reason.
-
- - Commands which delete text before the cursor, such as `dB', don't move the
- cursor, but they should.
-
- - Using the substitute command, it is not possible to replace with multi-
- line text using the ^V^M construct in the replacement string. Vi allows
- this as a special case.
-
- - The Elvis.prj file (used by Turbo-C under MS-DOS) does not force large model
- and the text segment is > 64K.
-
- - The visual "put" commands can't be repeated by hitting ".".
-
- - "!!ls %" doesn't expand %
-
- - Sideways scrolling is unacceptable for slow terminals.
-
- - The ":set number" option is missing, among other things.
-
- - In DOS, the default colors are not very good.
