Those arguments are passed straight to the C compiler.

Re: [Vala] Preprocessor defines via Meson or valac

[Guillaume Poirier-Morency via vala-list]

If I can suggest a small improvement, you could use the
declare_dependency mechanism to add the definition only to the targets
that link against libfuse:

   libfuse_dep = dependency('libfuse')
   libfuse26_dep = declare_dependency(dependencies: [libfuse_dep]. 
  compile_args: '-
   DFUSE_USE_VERSION=26')

   executable('mount', 'mount.c', dependencies: [libfuse26_dep])

Try to split the arguments in two or remove the space between '-D' and
'FUSE_USE_VERSION=26'.

Like mentioned elsewhere, you will have to set language: 'c' for this
case to work.

Re: [Vala] Downloading only a portion in the latter part of a file from internet

[Guillaume Poirier-Morency via vala-list]

Your code is problematic: skipping the DataInputStream does not guarantee
you that the underlying FileInputStream will be positioned at the desired
byte offset when skipped. This is due to the buffering.

If you are to operate on your stream via a DataInputStream, use it
exclusively:

var dis = DataInputStream(file_stream)
dis.skip(80);

uint8 buffer[160];

size_t buffer_len;

dis.read_all(buffer, out buffer_len);


Alternatively, you should consider an HTTP range query, which will allow
you to do the skip operation at zero-cost. It's a bit more boilerplate to
set up the session and the HTTP message, but might be worth it if you skip
numerous bytes.

Just a suggestion: you should setup a simple GitHub page from the
repository and ship sources as assets in empty releases if you don't
intend to distribute the source code. 

I'm not a big fan of freeware, but since we already display IDE like
IntelliJ and TextMate, I think it's fine to put your work as well.

What features are implemented so far?
