(hoping this is of interest for hackers- too)
One of the most annoying features of chromium is that it downloads
instead of displaying various types of files (.c, .h and so on).
After a bit of investigation i found that at least for local files
you can override this by defining your preferred mime types in
~/.local/share/mime/globs2 as follows:
> cat ~/.local/share/mime/globs2
10:text/plain:*.c
10:text/plain:*.cc
10:text/plain:*.c++
10:text/plain:*.cpp
10:text/plain:*.h
The first field is the priority (smaller number means more important),
then follows the mime type, then the pattern that you are matching.
The default rules (/usr/local/share/ ...) have a priority of 50
for .c, .h and so on.
For remotely-served files, the browser relies on the MIME Type
supplied by the server and the trick above does not work.
Looking at the Chromium sources
chromium-courgette-redacted-18.0.1025.162/net/base/mime_util.cc
it seems that a partial fix can be achieved by arring the list of
types we want to display to the array
static const char* const supported_non_image_types[] = {
...
+ "text/x-csrc",
+ "text/x-chdr",
...
}
Maybe we can have some optional patch to the FreeBSD port,
although i'd rather find a way to override the server-supplied
mime type in a way that does not require rebuilding Chrome.
Anyways, at least for local browsing, this seems a significant
improvement.
