|
|
default n
|
|
---help---
|
|
Enable support for NuttX tiny VI work-alike editor.
|
|
|
|
Omitted features:
|
|
- No keypad cursor control support
|
|
- No word oriented operations.
|
|
|
|
Assumptions and Limitations:
|
|
- A VT100 host terminal is assumed. At 115200 BAUD, screen
|
|
update times with a 24x64 edit region are noticeable but
|
|
acceptable.
|
|
- A fixed width character set (like Courier) is assumed
|
|
- Files are edited in memory so unless you have a lot of memory
|
|
to spare, this editor will only be useful for very small files.
|
|
|
|
Size: As of 2013-01-30, it appears that the size will vary from
|
|
about 8.5 to 10.5KB, depending upon the efficiency of the
|
|
underlying architecture.

The editor does not have the capability to query the display for
|
|
its width or height. This setting provides the default width of
|
|
the display in columns. The actually width can be overridden using
|
|
command line options.

|
|
|
|
Debug output is generated with syslog. The editor works on
|
|
/dev/console. In order to get both a usable display and also
|
|
readable debug output, syslog'ing should sent to some device other
|
|
than /dev/console (which is the default).
