Coding Style
|
||
------------
|
||
NetSurf's source is organised in modules. A module usually consists of a .c and
|
||
.h file. For example the html module is in html.c and html.h.
|
||
|
||
All functions (including static functions) in a module should start <module>_,
|
||
for example html_create(), html_process_data(), etc. This makes functions easy
|
||
to find and names unique through the source, which is<69>helpful for backtraces,
|
||
documentation, etc.
|
||
|
||
Global variables in a module (including static) should also start <module>_.
|
||
|
||
Static functions should all be declared at the top.
|
||
|
||
Put functions in a logical order, for example any init function first, then
|
||
functions it calls, then the next externally available function, functions it
|
||
calls, etc.
|
||
|
||
We use K&R (2nd edition ANSI C) style, tabs for indent, 80 characters wide,
|
||
lower_case_with_underscores.
|
||
|
||
See http://www.netsurf-browser.org/developers/StyleGuide.pdf for further
|
||
information and examples.
