Caret policy in SciTE
|
|
|
|
If slop is set, we can define a slop value.
|
|
This value defines an unwanted zone (UZ) where the caret is... unwanted.
|
|
This zone is defined as a number of pixels near the vertical margins,
|
|
and as a number of lines near the horizontal margins.
|
|
By keeping the caret away from the edges, it is seen within its context,
|
|
so it is likely that the identifier that the caret is on can be completely seen,
|
|
and that the current line is seen with some of the lines following it which are
|
|
often dependent on that line.
|
|
|
|
If strict is set, the policy is enforced... strictly.
|
|
The caret is centred on the display if slop is not set,
|
|
and cannot go in the UZ if slop is set.
|
|
|
|
If jumps is set, the display is moved more energetically
|
|
so the caret can move in the same direction longer before the policy is applied again.
|
|
'3UZ' notation is used to indicate three time the size of the UZ as a distance to the margin.
|
|
|
|
If even is not set, instead of having symmetrical UZs,
|
|
the left and bottom UZs are extended up to right and top UZs respectively.
|
|
This way, we favour the displaying of useful information: the beginning of lines,
|
|
where most code reside, and the lines after the caret, eg. the body of a function.
|
|
|
|
| | | | |
