Bolts per pitch for multipitch climbs

[SyntaxPickax]

On bolted multi-pitch routes, it might be nice to specify the number of bolts per pitch without resorting to the description field. Unless I missed something, this is currently not supported.

You are right - there is currently no pitch structured data, except as part of the description.

There are some other priorities at the moment, but I guess at some stage we will have to seriously consider whether or not we add separate pitch info or just keep it in the description.

The big question is how we would use the data. At the moment the markdown semi -structured format works well for most cases and is succinct and easy to edit, but can be a little inconsistent as it's just a convention:

The only reason we would want to break it apart into is if we'd want to search or report on each tiny bit of data and that has to out weight the editing simplicity. The use cases I can see for this are:

• I only have 4 draws, what sport routes can I climb, - a multipitch might have 20 bolts but it could be 4 bolts per pitch and so be ok with only 4 draws.

At the moment when you create / edit a climb you can enter all the pitch grade and height data in one line like:

"12,18,17"

I'm wondering wether we can extend that to something like:

"12 20m 6,18 25m 3, 17 30m 7"

which captures grade, height and bolts and then pulls it apart. Heights would have to have a 'f' or 'm' to help the parsing separate it from a grade.

And then to make things even easier we could parse the markdown itself which has a lot more data and pull these same bits of data out. To make it clear this has worked when we present the markdown we should add some subtle styling to the grade and height so it's clear they have been understood, or we could even warn / alert if something looks weird when editing.

Related a little to #641 I just made

Agreed, it's hard for me to imagine other use cases. "12 20m 6,18 25m 3, 17 30m 7" does seem a bit complicated for one little textfield. In any event, I'm sure this feature could wait.

Vaguely related to #1313 and #1314 we could make the bolts a textfield with a dropdown (instead of just dropdown), but it also accepts comma separated numbers like the heights and grades boxes.

Moved comment from @bing-li to here from https://github.com/theCrag/website/issues/3206:

Ideally also provide screenshots:

What you expected:

• "Bolts" is a edit box that can take an array, such as 9,6,8 for 3 pitches, similar to "Height" and "grade"
• and the bolts can be shown next to the grade and height
• the overall bolts of the mutli-pitch route is the max of each pitch

It would be nice to have this feature on multipitches :

• "Bolts" like a edit box that can take an array, such as 9,6,8 for 3 pitches, similar to "Height" and "grade".

• the bolts can be shown next to the grade and height

• the overall bolts of the multi-pitch route is the max of each pitch

The use cases I can see for this are:

* I only have 4 draws, what sport routes can I climb, - a multipitch might have 20 bolts but it could be 4 bolts per pitch and so be ok with only 4 draws.

Another use case I do quite often: Getting an objective information to estimate "how well bolted" or "which understanding of sport climbing" a route is by dividing the route's / pitch's length by amount of bolts. That average bolt density metric is more clear than some "low/medium/well bolted" icons in paper guidebooks – some "sport routes" in Germany have 2-3 bolts on 15m length... BTW, that metric would also be a nice filter for routes search.
