This changes Ex mode (Q, -e) to work like Vim's "improved Ex mode" (gQ, -E). That brings some small behavior differences, but should not impact most Ex scripts (unless, for example, they depend on mappings being disabled--but that can be solved for -e by skipping user config). Before this change: * the screen test hangs. After this change: * Q acts like gQ. * -e/-es differs from -E/-Es only in its treatment of stdin. This moves towards potentially removing getexmodeline(). (HINT: That does NOT mean "removing Ex mode", it means removing the Vi-compatible Ex mode, which differs from Vim's "improved Ex mode" only in some minor details (e.g. mappings are disabled).) ref #1089 :-)~

|
|

|
|
is a text editor based on Vim.
|
|
To enter commands in
|
|
.Nm ,

|
|
.Pq Sq \&:
|
|
which is also used in this manual to denote commands.
|

.It Ar file ...
|
|
File(s) to edit.
|
|
If none are specified, open an empty buffer.
|
|
If multiple files are specified, open one buffer for each file.
|
|
To switch between buffers, use the
|
|
.Ic :next

.It Fl

|
|
.It Fl t Ar tag
|
|
The file to edit and the initial cursor position depends on a
|
|
tag, a sort of goto label.
|
|
.Ar tag
|
|
is looked up in the tags file, the associated file becomes the current
|
|
file and the associated command is executed.
|
|
If
|
|
.Ar tag
|
|
is a function name, the file containing that function is opened
|
|
with the cursor positioned at the start of the function.
