Equations – automatic numbering

[ViktorfromCzechRep]

Hello, 

I have a big request. I have run into a problem with the automatic numbering of equations in Affinity Pubhlisher. 

I would need to create an automatic numbering for math equations so that the first number corresponds to the chapter number in which the equation is located. I am attaching an image for visualization. 

Thank you in advance for all the advice!

At first I thought this would be easy to do using the Fields panel, but annoyingly enough while there is a Section name field, there is no Chapter field, so I have no idea how this could be done.

I hope someone else knows of a way to do this.

Make and name the sections at the chapter starts and then name them 1., 2., 3. ... X. Include the dot/full stop/period in the name

But there is no way to automatically add the numbers after the section (chapter) names.

That would work if there was no need to name the sections to something other than the chapter number; otherwise not.

Hi @ViktorfromCzechRep!  If you can accept a small compromise, I think it is possible to do what you're after.  

In this example, the chapter numbers and the equation numbers are automatically generated.  The compromise is that I don't think there's a way to have the equation numbers placed to the right - but if you can accept them on the left and then followed by the equation, then you’re in business.

(This is a slightly simplified demo - an earlier trial version was more complex but went beyond demonstrating the basic principle, so I simplified it for now.)

You need two paragraph styles: one for the chapters and one for the equations.  As well as regular formatting they use multi-level numbering/lists.  Have a look at the "Chapter Title" and "Equation" paragraph styles in the attached sample file.  In particular, take a look at the Bullets and Numbering section of each of those two styles.

In this simplified example, set any empty paragraph to use the "Chapter Title" paragraphstyle.  Set your equations to use "Equation".  (Making your equations red is strictly optional!  I just did that to make them stand out. 😀)

Does that help?  (If the numbers must be on the right, I do have half an idea, but it's after midnight here so I'm stopping for today.)

Maybe a regular expression based search/match/replace run will do the job afterwards for the equations.

1. Aka for let's say the text:   (1.2)  y = m c
2. The reg expr:                       (\([0-9]+\.[0-9]+\)) (.+)  => \2\1
3. Should yield to:                  y = m c  (1.2)

Nice:) To achieve the initially requested layout, how about adding a tab between the two result groups:

\2\t\1
