Global variables in Definitions

[alfaromartino]

Suppose that I have some variable defined in config.md, let's call it id. And now I want to use that variable when I define the title, in the block wrapped by +++. Is it possible? So far, Franklin says id doesn't exist.

My goal? I wanted to define an ordered list of files in config.m, and then use eachindex to give a number to each. Then, I wanted to add that number to title on each local page. But it seems that global variables are not allowed within +++?

Thanks!

If you define a variable in config.md you can access it in local pages with globvar(:name_of_var) so e.g.

config.md:

+++
a = "hello from global"
b = 235
+++

page1.md:

+++
c = globvar(:b)
+++

This is `c`: {{c}}

Assuming you have something like <title>{{title}}</title> in your layout files, you could also have on page1.md:

+++
title = globvar(:a)
+++

and the title of that tab/page will be "hello from global".

I hope that gives you elements to do what you wish for.

Note: just in case, from your description it seems you might need to use fd_rpath on local pages i.e. locvar(:fd_rpath) this will return the relative path to the current file. You can test it by adding

Current relative path: **{{fd_rpath}}**

on pages and seeing what it shows.

(closing but feel free to reopen if you still have questions)

I'm not with my computer now, but it seems that it's what I was looking for!
Many thanks!
