Vi incompatibility:
|
||||
- Try new POSIX tests, made after my comments. (Geoff Clare, 2005 April 7)
|
||||
Version 1.5 is in ~/src/posix/1.5. (Lynne Canal)
|
||||
8 With undo/redo only marks in the changed lines should be changed. Other
|
||||
marks should be kept. Vi keeps each mark at the same text, even when it
|
||||
is deleted or restored. (Webb)
|
||||
Also: A mark is lost after: make change, undo, redo and undo.
|
||||
Example: "{d''" then "u" then "d''": deletes an extra line, because the ''
|
||||
position is one line down. (Veselinovic)
|
||||
8 When stdin is not a tty, and Vim reads commands from it, an error should
|
||||
make Vim exit.
|
||||
7 Unix Vim (not gvim): Typing CTRL-C in Ex mode should finish the line
|
||||
(currently you can continue typing, but it's truncated later anyway).
|
||||
Requires a way to make CTRL-C interrupt select() when in cooked input.
|
||||
8 When loading a file in the .exrc, Vi loads the argument anyway. Vim skips
|
||||
loading the argument if there is a file already. When no file argument
|
||||
given, Vi starts with an empty buffer, Vim keeps the loaded file. (Bearded)
|
||||
6 In Insert mode, when using <BS> or <Del>, don't wipe out the text, but
|
||||
only move back the cursor. Behaves like '$' in 'cpoptions'. Use a flag
|
||||
in 'cpoptions' to switch this on/off.
|
||||
8 When editing a file which is a symbolic link, and then opening another
|
||||
symbolic link on the same file, Vim uses the name of the first one.
|
||||
Adjust the file name in the buffer to the last one used? Use several file
|
||||
names in one buffer???
|
||||
Also: When first editing file "test", which is symlink to "test2", and
|
||||
then editing "test2", you end up editing buffer "test" again. It's not
|
||||
logical that the name that was first used sticks with the buffer.
|
||||
7 The ":undo" command works differently in Ex mode. Edit a file, make some
|
||||
changes, "Q", "undo" and _all_ changes are undone, like the ":visual"
|
||||
command was one command.
|
||||
On the other hand, an ":undo" command in an Ex script only undoes the last
|
||||
change (e.g., use two :append commands, then :undo).
|
||||
7 The ":map" command output overwrites the command. Perhaps it should keep
|
||||
the ":map" when it's used without arguments?
|
||||
7 CTRL-L is not the end of a section? It is for Posix! Make it an option.
|
||||
7 Implement 'prompt' option. Init to off when stdin is not a tty.
|
||||
7 CTRL-T in Insert mode inserts 'shiftwidth' of spaces at the cursor. Add a
|
||||
flag in 'cpoptions' for this.
|
||||
7 Add a way to send an email for a crashed edit session. Create a file when
|
||||
making changes (containing name of the swap file), delete it when writing
|
||||
the file. Supply a program that can check for crashed sessions (either
|
||||
all, for a system startup, or for one user, for in a .login file).
|
||||
7 Vi doesn't do autoindenting when input is not from a tty (in Ex mode).
|
||||
7 "z3<CR>" should still use the whole window, but only redisplay 3 lines.
|
||||
7 ":tag xx" should move the cursor to the first non-blank. Or should it go
|
||||
to the match with the tag? Option?
|
||||
7 Implement 'autoprint'/'ap' option.
|
||||
7 Add flag in 'cpoptions' that makes <BS> after a count work like <Del>
|
||||
(Sayre).
|
||||
7 Add flag in 'cpoptions' that makes operator (yank, filter) not move the
|
||||
cursor, at least when cancelled. (default Vi compatible).
|
||||
7 This Vi-trick doesn't work: "Q" to go to Ex mode, then "g/pattern/visual".
|
||||
In Vi you can edit in visual mode, and when doing "Q" you jump to the next
|
||||
match. Nvi can do it too.
|
||||
7 Support '\' for line continuation in Ex mode for these commands: (Luebking)
|
||||
g/./a\ g/pattern1/ s/pattern2/rep1\\
|
||||
line 1\ line 2\\
|
||||
line 2\ line 3\\
|
||||
. line4/
|
||||
6 ":e /tmp/$tty" doesn't work. ":e $uid" does. Is $tty not set because of
|
||||
the way the shell is started?
|
||||
6 Vi compatibility (optional): make "ia<CR><ESC>10." do the same strange
|
||||
thing. (only repeat insert for the first line).
|
||||

||||

|

In 2005 the POSIX test suite was run to check the compatibility of Vim. Most
|
||||
of the test was executed properly. There are the few things where Vim
|
||||
is not POSIX compliant, even when run in Vi compatibility mode.
|
||||
|
||||
Set the $VIM_POSIX environment variable to have 'cpoptions' include the POSIX
|
||||
flags when Vim starts up. This makes Vim run as POSIX as it can. That's
|
||||
a bit different from being Vi compatible.
|
||||
|
||||
This is where Vim does not behave as POSIX specifies and why:
|
||||
|
||||
*posix-screen-size*
|
||||
The $COLUMNS and $LINES environment variables are ignored by Vim if
|
||||
the size can be obtained from the terminal in a more reliable way.
|
||||
Add the '|' flag to 'cpoptions' to have $COLUMNS and $LINES overrule
|
||||
sizes obtained in another way.
|
||||
|
||||
The "{" and "}" commands don't stop at a "{" in the original Vi, but
|
||||
POSIX specifies it does. Add the '{' flag to 'cpoptions' if you want
|
||||
it the POSIX way.
|
||||
|
||||
The "D", "o" and "O" commands accept a count. Also when repeated.
|
||||
Add the '#' flag to 'cpoptions' if you want to ignore the count.
|
||||
|
||||
The ":cd" command fails if the current buffer is modified when the '.'
|
||||
flag is present in 'cpoptions'.
|
||||
|
||||
There is no ATTENTION message, the "A" flag is added to 'shortmess'.
|
||||

||||
