Failed to serve Literate.jl scripte with ERROR: MethodError: no method matching isless

[newptcai]

I am trying to run a quite simple Literate.jl script.

# #A test

3+3

Here's my markdown file

@def tags = ["mathematics", "blog", "programming", "Julia"]
@def showall = true

\literate{/_literate/test.jl}

But I get the following error

julia> serve()

hmm thanks for the report, can you comment out the @def tags line and try again to confirm that it works without tags? I'll investigate why the tags specifically make the literate page fail.

[newptcai]

Yes, it is the problem of tag. Removing it and everything works.

BTW, is there anyway to hide the code and only keep outputs?

[tlienart]

yes put #hideall in the code blocks you want to hide

So in the case of a literate file you'll need to add this multiple times:

# #A test

#hideall
r = 3+3
print(r)

# some text here

#hideall
r = 5 * 4
print(r)

# some more text

https://franklinjl.org/code/#hiding_lines

[tlienart]

PS: I guess we could provide a page-wide "hide everything", I just hadn't had the need for it yet but this could be done if you don't like the multiple "hide all" from my previous comment

[newptcai]

A "hide all" would be indeed useful. I just want to show some pictures in a blog post, not the code.
