# Working with the team
Generally it is sensible to check with the other developers if you are
planning to make a change to NetSurf intended to be merged.
We are often about on the IRC channel but failing that the developer
mailing list is a good place to try.
All the project sources are held in [public git repositories](http://source.netsurf-browser.org/)
# Compilation environment
Compiling a development edition of NetSurf requires a POSIX style
environment. Typically this means a Linux based system although Free
BSD, Open BSD, Mac OS X and Haiku all known to work.
Compilation for non POSIX toolkits/frontends (e.g. RISC OS) generally
relies upon a cross compilation environment which is generated using
the makefiles found in our
repository. These toolchains are built by the Continuous Integration
(CI) system and the
[results of the system](http://ci.netsurf-browser.org/builds/toolchains/)
are published as a convenience.
## Quick setup
The [quick start guide](docs/quick-start.md) can be used to get a
development environment setup quickly and uses the
[env.sh](env_8sh_source.html) script the core team utilises.
## Manual setup
The Manual environment setup and compilation method is covered by the
details in the [netsurf libraries](docs/netsurf-libraries.md) document
for the core libraries and then one of the building documents for the
- [Amiga Os cross](docs/building-AmigaCross.md) and [Amiga OS](docs/building-AmigaOS.md)
- [Haiku (BeOS)](docs/building-Haiku.md)
- [Windows Win32](docs/building-Windows.md)
These documents are sometimes not completely up to
date and the env.sh script should be considered canonical.
The [logging](docs/logging.md) interface controls debug and error
messages not output through the GUI.
# Unit testing
NetSurf [unit tests](docs/unit-testing.md) provide basic test coverage
of many core parts of the browser code such as url parsing and utility
# Integration testing
The monkey frontend is used to perform complex tests involving
operating the browser as a user might (opening windows, navigating to
websites and rendering the contents etc.)
A test is written as a set of operations in a yaml file. A test can be
run using the monkey_driver.py python script
$ ./test/monkey_driver.py -m ./nsmonkey -t test/monkey-tests/start-stop.yaml
There are very few tests within the netsurf repository. The large
majority of integration tests are held within the
To allow more effective use of these tests additional infrastructure
has been constructed to allow groupings of tests to be run. This is
used extensively by the CI system to perform integration testing on
Each test is a member of a group and the tests within each group are
run together. Groups are listed within division index files. To run
the integration tests the monkey-see-monkey-do python script is
used. It downloads the test plan for a division from the netsurf test
infrastructrure and executes it.

# Documented API
The NetSurf code makes use of Doxygen for code documentation.
There are several documents which detail specific aspects of the
codebase and APIs.
## Core window
The [core window API](docs/core-window-interface.md) allows frontends
to use generic core code for user interface elements beyond the
## Source object caching
The [source object caching](docs/source-object-backing-store.md)
provides a way for downloaded content to be kept on a persistent
storage medium such as hard disc to make future retrieval of that
- An engine that takes source code and executes it.
- Interfaces between the program and the web page.
- Browser support to retrieve and manage the source code to be executed.
- Browser support for the dispatch of events from user interface.
[instructions](docs/updating-duktape.md) on how to update the library.
## Interface binding
it must use the Document Object Model (DOM) and Cascading Style Sheet
Object Model (CSSOM) API.
These interfaces are described using web Interface Description
Language (IDL) within the relevant specifications
Each interface described by the webIDL must be bound (connected) to
the browsers internal representation for the DOM or CSS, etc. The
process of [writing bindings](docs/jsbinding.md) is ongoing.
