Re: Reading a directory

[Urs Liska]

Hi David and Ralf,

thank you for the hints. Actually readdir was where I'd already landed, but I hadn't got it to run.

Now it's possible to do:

\include "openlilylib"
\useLibrary stylesheets
\displayNotationFonts

===>

Installed notation fonts:

OpenType:

- arnold

- beethoven

- cadence (no brace font)

- emmentaler

- gonville

- gutenberg1939

- haydn

- improviso

- lilyboulez (no brace font)

- lilyjazz

- paganini (no brace font)

- profondo

- ross

- scorlatti (no brace font)

- sebastiano

SVG:

- beethoven

- cadence (no brace font)

- emmentaler

- gonville

- gutenberg1939

- haydn

- improviso

- lilyboulez (no brace font)

- lilyjazz

- paganini (no brace font)

- profondo

- ross

- scorlatti (no brace font)

- sebastiano

:-)

Best
Urs

Hi Urs,

you need the opendir-readdir-closedir combo:

 (let ((dir (opendir "/etc/")))
   (readdir dir)
   .....
  (closedir dir))

This is pretty well hidden in the 1.8 manual.  I found opendir in the procedure index under its C name: scm_opendir.  Here's the page with related stuff:
