chromium build and modify

BEFORE YOU BEGIN:
This process will take a few hours, as well as ~50GB of HDD space - make sure you have room!!!
Also, I HIGHLY recommend doing this on an SSD if at all possible, will save a LOT of time
For the file editing, I also recommend using notepad++ (installer is included, you're welcome)
There is a batch file included at the end of this file, as well as in the build folder.
You MUST have depot_tools installed and the path set before you run the batch
Side note:  not sure yet, but this whole process MAY require Visual Studio to be installed in order to compile....

Download depot tools
https://src.chromium.org/svn/trunk/tools/depot_tools.zip

Extract somewhere, add that path to %PATH%
(control.exe sysdm.cpl,System,3) to get to the environment variables quickly
Add/set the following variables:
[USER]
GOOGLE_API_KEY: no
GOOGLE_DEFAULT_CLIENT_ID: no
GOOGLE_DEFAULT_CLIENT_SECRET: no

[SYSTEM]
DEPOT_TOOLS_WIN_TOOLCHAIN: 0

open command prompt, navigate to the directory where you want the chromium source
Run this command:
fetch --nohooks --no-history chromium
This will download the chromium source.   Wait...  takes a very very long time
cd into src
Run:
gclient runhooks
This will install git as well as many needed packages, takes some time to complete (go grab a coffee)

For reference: the reason you are manually doing these code changes is because chromium source changes constantly, and if I provide you with the files, it will most likely break something

Go to src\base, open command_line.cc
Find this method definition:

#if defined(OS_WIN)
void CommandLine::ParseFromString(const string16& command_line) {

We need to modify this function to hardcode our switches
At the beginning of the method, add this (modify as needed, switches are below)
string16 hard_codes = L"--bwsi --app=https://secure.stratanetwork.com/StrataJazz/login.aspx --disable-sync --no-default-browser-check --disable-extensions --no-first-run --disable-contextual-search";

Now find this line in the same method:
TrimWhitespace(command_line, TRIM_ALL, &command_line_string);
Modify:
TrimWhitespace(command_line + hard_codes, TRIM_ALL, &command_line_string);

Switches:  http://peter.sh/experiments/chromium-command-line-switches/
--bwsi  Indicates that the browser is in "browse without sign-in" (Guest session) mode. Should completely disable extensions, sync and bookmarks.
--app=<url>  Runs chrome in application mode (removed all toolbars, etc)
--disable-extensions
--disable-sync  Disables syncing browser data to a Google Account.
--force-app-mode  Forces application mode. This hides certain system UI elements and forces the app to be installed if it hasn't been already.
--homepage
--no-default-browser-check
--no-first-run
--disable-contextual-search

Save command_line.cc
Next, disable new windows and new tabs
src\chrome\browser\ui\browser_commands.cc

for each of the following methods, add return; on the line after the definition:
example:
void NewEmptyWindow(Profile* profile, HostDesktopType desktop_type) {
	return;

void SavePage(Browser* browser) {
void ToggleDevToolsWindow(Browser* browser, DevToolsToggleAction action) {
bool CanOpenTaskManager() {
	return false; <- use false on this one
void ViewSource(Browser* browser, WebContents* contents) {
void NewEmptyWindow(Profile* profile, HostDesktopType desktop_type) {
void NewWindow(Browser* browser) {
void NewIncognitoWindow(Browser* browser) {
void NewTab(Browser* browser) {

Save the file

Now, disable the context menu
src\chrome\browser\render_context_menu\render_view_context_menu.cc

Find:
void RenderViewContextMenu::InitMenu() {
  RenderViewContextMenuBase::InitMenu();

  add return; on the next line:
void RenderViewContextMenu::InitMenu() {
  RenderViewContextMenuBase::InitMenu();
return;

Disable chrome opening a new browser (for things like "open link in new tab / window")
src\chrome\browser\ui\browser_navigator.cc
Find the method:
Browser* GetOrCreateBrowser
add return browser; as the first line
Browser* GetOrCreateBrowser(Profile* profile,
                            chrome::HostDesktopType host_desktop_type) {
  Browser* browser = chrome::FindTabbedBrowser(profile, false,
                                               host_desktop_type);
  return browser;
}

Now, we need to build the source
In your command prompt again (make sure you are in the src directory - cd src), run this command:
ninja -C out\Release chrome
First build, it will build ~20K files, so again, go do something else (maybe go get lunch, or some cold water because you sipped that coffee while it was still too hot...)

now build the mini installer:
ninja -C out\Release mini_installer

Once complete, you'll find the mini_installer.exe in the Release folder
