History of Synergy
==================
The first incarnation of synergy was CosmoSynergy, created by
Richard Lee and Adam Feder then at Cosmo Software, Inc., a
subsidiary of SGI (nee Silicon Graphics, Inc.), at the end of
1996. They wrote it, and Chris Schoeneman contributed, to
solve a problem: most of the engineers in Cosmo Software had
both an Irix and a Windows box on their desks and switchboxes
were expensive and annoying. CosmoSynergy was a great success
but Cosmo Software declined to productize it and the company
was later closed.
Synergy is a from-scratch reimplementation of CosmoSynergy.
It provides most of the features of the original and adds a
few improvements.

Synergy Developer and Porting Guide
===================================
This document is under development.
Code Organization
-----------------
The synergy source code organization is:
. -- root makefiles, some standard documentation
cmd -- program source code
synergy -- synergy client
synergyd -- synergy server
config -- stuff for autoconf/automake
dist -- files for creating distributions
rpm -- files for creating RPMs
doc -- placeholder for documentation
examples -- example files
lib -- library source code
base -- simple utilities
client -- synergy client library
http -- simple http tools
io -- I/O
mt -- multithreading
net -- networking
platform -- platform dependent display/window/event stuff
server -- synergy server library
synergy -- synergy shared client/server code library
Note how the utility code required by the programs is placed into
separate library directories. This makes the makefiles a little
more awkward but makes for a cleaner organization. The top level
directory has only the standard documentation files and the files
necessary to configure and build the rest of the project.
Coding Style Guide
------------------
Synergy uses many coding conventions. Contributed code should
following these guidelines.
- Dependencies
* No circular library dependencies
Library dependencies form an acyclic graph. Conceptually
libraries can be arranged in layers where each library only
references libraries in layers below it, not in the same
layer or layers above it. The makefiles build the lowest
layer libraries first and work upwards.
* Avoid circular uses-a relationships
When possible, design classes with one-way uses-a relationships
and avoid cycles. This makes it easier to understand the code.
However, sometimes it's not always practical so it is permitted.
- C++
* C++ features
Synergy uses the following more recent C++ features:
* bool
* templates
* exceptions
* mutable
* new scoping rules
* the standard C++ library
Do not use the following C++ features:
* dynamic_cast
* run time type information
* namespaces and using (use std:: where necessary)
The new scoping rules say that the scope of a variable declared
in a for statement is limited to the for loop. For example:
for (int i = 0; i < 10; ++i) {
// i is in scope here
}
// i is not in scope here
for (int i = -10; i < 0; ++i) {
// an entirely new i is in scope here
}
// i is not in scope here
This is used routinely in synergy, but only in for loops. There
is a macro for `for' in lib/base/common.h when building under
Microsoft Visual C++ that works around the fact that that compiler
doesn't follow the new scoping rules. Use the macro if your
compiler using the old scoping rules.
* Standard C++ library
The standard C++ library containers should always be used in favor
of custom containers wherever reasonable. std::string is used
throughout synergy but only as the CString typedef; always use
CString, never std::string. Synergy avoids using auto_ptr due to
some portability problems. Synergy makes limited use of standard
algorithms and streams but they can be freely used in new code.
* Limited multiple inheritance
Classes should inherit implementation from at most one superclass.
Inheriting implementation from multiple classes can have unpleasant
consequences in C++ due to it's limited capabilities. Classes can
inherit from any number of interface classes. An interface class
provides only pure virtual methods.
Synergy breaks this rule in two places. First is that IInterface
implements the virtual destructor. However, it's just an empty
method so it doesn't really count. Second is MXErrno which provides
implementation for exceptions that use the global errno variable.
* No globals
Avoid global variables. All global variables must be static, making
it visible only with its source file. Most uses of global variables
are better served by static data members of a class. Global
constants are permitted in some circumstances.
Also avoid global functions. Use public static member functions in
a class instead.
These rules are violated by the main source file for each program
(except that the globals are still static). They could easily be
rewritten to put all the variables and functions into a class but
there's little to be gained by that.
* Private data only
If a class is plain-old-data (i.e. it has no methods) all of its
data members should be public. Otherwise all of its data members
should be private, not public or protected. This makes it much
easier to track the use of a member when reading code. Protected
data is not allowed because `protected' is a synonym for `public
to my subclasses' and public data is Bad Thing. While it might
seem okay in this limited situation, the situation is not at all
limited since an arbitrary number of classes can be derived,
directly or indirectly, from the class and any of those classes
have full access to the protected data.
* Don't test for NULL when using `delete' or `delete[]'
It's unnecessary since delete does it anyway.
- Naming
Names always begin with a letter (never an underscore). The first
letter of interior names are always capitalized. Acronyms should
be all uppercase. For example: myTextAsASCII.
Names come it two flavors: leading capital and leading lowercase.
The former have the first character capitalized and the latter
don't. In the following table, leading capital names are indicated
by `Name' and leading lowercase names by `name'.
The naming convention for various things are:
* Exceptions -- X + Name XMyException
* Interfaces -- I + Name IMyInterface
* Template Classes -- T + Name TMyTemplate<>
* Other Classes -- C + Name CMyClass
* Enumerations -- E + Name EMyEnumeration
* Constants -- k + Name kMyConstant
* Data Members -- m_ + name m_myDataMember
* Methods -- name myMethod
* Functions -- name myFunction
* Variables -- name myVariable
Exceptions are types that get thrown and are generally derived
(possibly indirectly) from XBase. Interfaces are derived (possibly
indirectly) from IInterface and have only pure virtual functions.
Other classes are classes that aren't exceptions or interfaces.
Constants include global constants and enumerants.
- Formatting
Every project has its own formatting style and no style satisfies
everyone. New code should be consistent with existing code:
* Use tabs to indent
* Tabs are 4 columns
* Open braces ({) go on same line as introducing statement
`for (i = 0; i < 10; ++i) {' not
for (i = 0; i < 10; ++i)
{
* Close braces line up with introducing statement
* Open brace for function is on a line by itself in first column
* Close brace for function lines up with open brace
* Always use braces on: if, else, for, while, do, switch
* `else {' goes on it's own line
* Always explicitly test pointers against NULL
e.g. `if (ptr == NULL)' not `if (ptr)'
* Put spaces around binary operators and after statements
e.g. `if (a == b) {' not `if(a==b){'
* C'tor initializers are one per line, indented one tab stop
* Other indentation should follow existing practice
* Use Qt style comments for extraction by doxygen
* Mark incomplete or buggy code with `FIXME'
Class Relationships
-------------------
The doxygen documentation can help in understanding the relationships
between objects. Use `make doxygen' in the top level directory to
create the doxygen documentation into doc/doxygen/html. You must have
doxygen installed, of course.
