How to display these characters

How to display these characters

[juh+ntg-context--- via ntg-context]

Dear all,

I have this:


\starttext

\starttyping
foo
└── bar
     ├── baz
     │   └── index.html
     └── index.html

\stoptyping

\stoptext

The source code is generated with the linux command "tree".

The special characters which indicate the folder depth are not displayed.

I guess that I could define a fallbackfont. Do anyone know the unicode 
range that should be covered and the font that has these characters?

TIA
juh

You need box drawing [1] characters.

When you need fonts with a wide range of character the Noto [2] family 
is a good choice.

%%%% begin example
\definefontfamily [noto] [rm] [Noto Serif]
\definefontfamily [noto] [ss] [Noto Sans]
\definefontfamily [noto] [tt] [Noto Sans Mono]
\definetypeface   [noto] [mm] [math] [pagella] [default]

\setupbodyfont [noto]

\starttext

\starttyping
foo
└── bar
     ├── baz
     │   └── index.html
     └── index.html
\stoptyping

\stoptext
%%%% end example

Yes, also e.g. Segoe UI Symbols, Apple Symbols, Symbola, Droid Sans 
Fallback.

I recently had the same problem and was wondering if there isn’t a 
Metapost module for directory trees?

There is a Metapost/Context module for drawing flow charts that should 
handle this nicely.

There is also a Metapost module for drawing relational charts ("nodes") 
that could be another approach.

If that’s still the same module that I know, then I don’t think it’s 
suitable (too much fixed on a grid).

I actually never really looked into the nodes module, but I guess that 
would work.

There is a simple LaTeX / plain TeX package [1] for this but I don't 
know if the plain TeX version works with ConTeXt.

That is advertised as “like Windows Explorer”, so I expected folder and 
file icons, but it makes quite ugly lines with square nodes.
Line drawing glyphs look better IMO, and the MP nodes module is probably 
even better, but I need to try...

Looking at the documentation, it appears that the size of the square node is configurable. So, if you set the size to be the same as line width, the square will be invisible.

It should be relatively easy to write a function that draws such trees without using any module as well.
