- @{{{ ViOri-Reference-Card
- This is a very Beta release of the vi bindings. It is not as bad as the
- previous release which was not really useable by anyone but me.
-
- HELP is bound to H in command mode.
-
- @{{{ History
- The first release (well, escape really) was something like 0.4, followed
- by 0.5, both of which required that the user type ESC twice to exit insert
- mode/enter command mode. I have now added cursor key support, though not
- yet anything for home etc. As a result, one can now type escape once to
- enter command mode. This may at first sight appear to be a minor change,
- but it involved a nasty hack, as it is difficult to tell appart cursor
- keys which start with ESC and other key sequences which really are legal
- vi commands, without a timeout. As a result certain terminals may have
- problems. Xterm, for instance will not keybind unless the keys are mapped
- so that sun escape sequences are produced (as determined by autoalias.)
- This is because xterm produces ESC O as the prefix for a cursor key
- (":ku=\EOA:kd=\EOB:kr=\EOC:kl=\EOD:" from our /etc/termcap)
- @}}}
- @{{{ Motion
- The way which motion is are defined is somewhat different to the standard
- vi method. The start of the motion is indicated by the command letter in
- the usual way, but the end of the motion is indicated be repeating the
- command letter. Thus to delete 2 lines djd is used instead of dj or 2dd.
- Trying to delete 8 lines with 8dd or d8d does not work, but d8jd does.
- This has the nice side effect that one does not have to count lines or set
- marks to delete or yank, but can wander through the file, possibly marking
- a whole procedure or block in one delete/yank command.
- @}}}
- @{{{ Folding
- FOLDING is done in exacly the same way with V.........V to mark the start
- and end of a new fold. To be completely honest, the Delete and yank
- commands are build on top of folding, this being the reason why the other
- commands are structured the way they are. I do intend to implement the
- traditional VI motions, but need some more time warp to do this.
-
- FOLD COMMANDS are prefixed by v in command mode

- @{{{ Multiple Buffers
- MULTIPLE BUFFERS can be created with =A and =o
- for adjacent Right (analog to A for Append to line)
- and below (analog to o for open.)
-
- One can change between buffers with =h =j =k =l or the arrow keys with =
- as a prefix. =r causes cursor motion to resize the current window, and all
- the other windows as appropriate.
- @}}}
- @{{{ Mouse
- The MOUSE can be used to change windows, to scroll by clicking at the
- appporiate edge of the window for a given buffer, and to move the cursor.
- Thus folding yanking and deletion of large areas of text can be done with
- 2 keyboard actions (eg V and V) and the mouse. The support is almost
- exactly that of Modeori
- @}}}
- @{{{ Bugs
- S and C are dangerous
-
- U and u are not implemented.
-
- y is currently broken (it worked once upon a 1.6.25 or so...)
-
- p and P sometimes unfold lines you do not expect to see unfolding.
-
- r (which is completely trivial and has worked since 1.6.25) ceased to
- work in version 1.6.63 or so without my even having touched the OCL code.
- search and replace does not yet work.
-
- Internal problems with screen-on and screen-of mean that using ex mode
- is hairy. An exact emulation of ex mode will not be provided as it is
- not sensible to emulate these features under origami. An alternative to
- ex mode will be provided, which is consistent with the Origami way of
- doing things. (ie How does Modeori/viori do something analagous.)
- @}}}
- @{{{ (Un)Acknowledgements
- I started writing this binding in 1991 on the Sun cluster in the
- Informatik Computer pool at the RWTH Aachen.
-
- Wolfgang Stumvoll has spent many a day explaining the interals of origami,
- and has suggested many of the solutions to the problems which cropped up
- on the way, not to mention debugging help etc.
-
- I wish to thank my employer Aqua_plan in Aachen for allowing me to
- continue this work, and for the several Megabytes of disk which my
- development requires, not to mention the CPU hours.... The transition from
- the cruddy version previously let out to this not so cruddy version 0.a
- took place entirely in February/March 1993!
-
- @if-using ( sarcasm )
- My previous employer ought to be thankful (but isn't) that I invested
- all the time I should have been hacking Origami between the 13.1.1992
- and 31.10.1992 in finding the fundamental design bug in the project.
- Read the F**king manuals Guys!
-
- My previous employer ought to be even more thankful that I am not going
- to name the company here.
