How to score a glissendo / slide

[SteveALee]

Is it possible to have a slide / glissendo? I can't see it in the source and I'm not sure the abc specification supports it. I tried a slur and tie but they really don't look or sound right.

+1 this feature request.

abc2svg extended the abc standard to incorporate this functionality.

!-(! !-)!
    glissendo (straight line)
!~(! !~)!
    glissendo (squiggly line)

So this code:

X:
K:
!~(! C2 !~)! c2 \
!~(! c2 !~)! C2 | \
!-(! C2 !-)! c2 \
!-(! c2 !-)! C2 |

Produces this rendering in abc2svg (try it in live editor):

I wasn't aware of that notation. I don't think that will be too hard to do, then. I'll work it in, but not sure how soon.
