Calligraphic pens and paths
Is there any hope that Inkscape will ever allow to apply calligraphic pens to paths the way Illustrator does? Is it hard to implement? Are the Adobe guys sitting on some patent there? Is it only I who want it?
It would create a dedicated Linux user as it would remove my last incentive to ever use Windows...

You can in 0.47 - copy any stroke shape and use "from clipboard" for "shape" in pen or pencil, then copy it and path > "paste path effect" on any preexisting path if necessary.

That's not the effect I'm after. I mean the one where the shape of the path simulates a stroke of a calligraphic pen. Some of us have shaky hands and no tablet, so the calligraphic pen tool doesn't quite give us what we want.
Or am I not doing it right?
Hi,
to accomplish that effect, you would be needing a stroke style with a non-square or non-circular (i.e. rectangular or elliptical) brush shape.
This is indeed a pretty common tool in f.e. Corel Draw... but now that you mention, I can't seem to find this in Inkscape... (I'm using 4.6 here though, haven't tried 4.7 yet)

Look at this screenshot http://www.inkscape.org/screenshots/gallery/inkscape-0.45-patternalongpath.p... is this what you asked for?
This is for the 0.45 version of Inkscape, path effects have gone a long way since then. In 0.46 you can do as shown in the screenshot ;)
In the development version that live path effect has been tied to Pen and Pencil tools, so as you're creating a path stroke with Pen tool it can automatically become like a brush stroke (if you've chosen an object to apply that looks like brush bristles). http://www.inkscapeforum.com/viewtopic.php?f=5&t=1794&p=9318&hil...

No, I mean like in this screenshot

It is like drawing along the path with a calligraphic pen, essentially as if an infinite number of lintel-shapes had been placed along the path, *without being rotated relative to one another*, as I've tried to harness my limited freehand drawing skills to show here:

As you see it may be treated as a number of shapes without relative rotation being placed along a path and an envelope drawn around them.

Different editors use different names for similar functions and similar names for different functions. Users are not very good in reproducing the vendors' terminology - they mostly prefer to invent their own descriptions for what they use. Different languages make this mess even worse.
The bottom line: please ALWAYS include a screenshot when requesting or inquiring about a feature. A picture is worth a million words.

I trust that my pictures, in spite of their shakiness, made my meaning clear?

It is possible to develop an extension to do this (or modify the path along path to have another option other than ribbon or snake...)
The problem is that you need to connect the successive shapes along the path which requires locating the tangential point on the pen tip for every subdivision of the path in order to connect the pen tips successfully.
It might be easier conceptually to do it the other way... i.e. make multiple copies of the path around the pen tip shape. Here was some manual playing:

alternately, instead of the straight line interpolation I show connecting the endpoints, segments from the original pen tip shape could be used to connect adjacent path copies.

I wonder how the Adobe folks are doing it...

It just hit me that Donald Knuth probably described the necessary math in The Metafont Book and adjacent works. Not that I'd understand the math...

Revised. The envelope on the lower right corner of the s was way too wide. It's still not right in the upper left corner but you get the idea, I hope.

Yes, mine was more of a meta-comment on the best discussion practices :)
As to your request, it is possible by the Pattern Along Path extension (not path effect!) if you choose the Ribbon mode, see:
http://inkscape.org/screenshots/gallery/inkscape-0.45-patternalongpath.png
It would be great if we could also have this option in the Pattern Along Path LPE (and then we could probably get rid of the extension)...

I tried but wouldn't get the right result. Perhaps I hadn't the right settings?

Not quite.
I tried to play with this, but it uses the pattern bounding box to connect the patterns. So you have to play with -ve offsets in the spacing to get it OK.
Also, the ribbon always makes the narrowest point vertical, rather than aligned with the pen nib, so to fake it you have to rotate the path and nib so the nib is horizontal first, then rotate it back afterwords.
The other problem is that the ribbon stretch doesn't preserve a minimum width, so a vertical line will end up thin, rather than the thickness of the "pen tip" shape. Here are examples:
