Description
v.segment - Creates points/segments from input vector lines and positions.
v.segment with an option for a fixed distance for points/segments (e.g. every 100m) would be nice.
the last segment may be shorter than the fixed distance.

as a workaround for points I've added a little addon:

Somebody must have read my mind.. I was just trying to figure out how to do this.v.to.points.
I only need points along straight lines, so using v.to.points (with use=vertex and dmax option set to a distance) seems to work too, although the results are slightly off from those created by the v.fixed.segmentpoints.
But +1 for me for adding this option to v.segment

to explain it a bit more: at the moment you can define points/segments by stdin input or a text file; that's nice.
the enhancement (two options: point or line, fixed distance) would be so that no stdin or a text file input is needed.
I just posted in #2231 a diff to v.split that implements a flag allowing to split lines according to a fixed distance. Combining this with v.to.points use=node should give you the points as well.

All enhancement tickets should be assigned to 7.6 milestone.
