### Execute Brave Browser Compilation Workflow

Source: https://context7.com/jaidcompiles/brave/llms.txt

Runs the complete Brave Browser compilation process, encompassing repository initialization, patching, configuration, and building. This function automates cloning the repository, installing dependencies, synchronizing source code, applying customizations, and generating the final executable. The output is typically located in the `src/out/Release/` directory.

```typescript
const compiler = new BraveCompiler({
  folder: 'C:/temp/brave-build',
  nodeInstallationFolder: 'C:/portable/node/24.11.1',
  arch: 'x64',
  os: 'win',
  flavor: 'jave',
  buildTarget: 'Release',
  lowMemory: false,
})

await compiler.run()
// Execution flow:
// 1. Clones brave-browser repository using direct download method
// 2. Patches init scripts to skip redundant npm installs
// 3. Runs npm install in brave-browser folder
// 4. Runs npm run init with target_os and target_arch
// 5. Runs npm install in brave-core folder
// 6. Runs npm run sync to download Chromium source
// 7. Applies customizations if flavor is 'jave'
// 8. Patches GN script to support custom --gn arguments
// 9. Generates build files with GN
// 10. Verifies output executable exists
// Expected output: jave.exe or brave.exe in src/out/Release/
```

### Initialize Brave Browser Compiler Instance

Source: https://context7.com/jaidcompiles/brave/llms.txt

Creates a new BraveCompiler instance, setting up configuration options for the target platform, architecture, build type, and customization level. It automatically configures environment variables, GN build options, and prepares the build environment, including disabling unwanted features if a custom flavor is specified. Dependencies include the 'forward-slash-path' module for path manipulation.

```typescript
import {BraveCompiler} from './lib/BraveCompiler.ts'
import * as path from 'forward-slash-path'

const compiler = new BraveCompiler({
  folder: path.join('C:', 'temp', 'brave-build'),
  nodeInstallationFolder: 'C:/portable/node/24.11.1',
  arch: 'x64',
  os: 'win',
  flavor: 'jave', // 'brave' for vanilla, 'jave' for customized
  buildTarget: 'Release',
  lowMemory: true, // Set to true to use jobs:1 for low-memory systems
  personalArch: 'znver2', // Optional: CPU-specific optimization
})

// The compiler automatically:
// - Sets up environment variables for Node.js and depot_tools
// - Configures GN build options with dummy API keys
// - Prepares temporary folder structure
// - Disables unwanted features if flavor is 'jave'
```

### Generate Git Config from Options (TypeScript)

Source: https://context7.com/jaidcompiles/brave/llms.txt

Generates a Git configuration file content from a structured JavaScript object. It takes Git options as input and outputs a string formatted as a Git config file. This is useful for programmatic configuration of Git settings within a build process.

```typescript
import {Compiler} from './lib/Compiler.ts'

const compiler = new Compiler({
  folder: '/tmp/build',
  gitOptions: {
    core: {
      longpaths: true,
      autocrlf: false,
      eol: 'lf',
      checkStat: 'minimal',
    },
    fetch: {
      negotiationAlgorithm: 'skipping',
    },
    diff: {
      algorithm: 'histogram',
    },
  },
})

// Render as Git config file format
const configContent = compiler.renderGitConfig()
console.log(configContent)
// Output:
// [core]
//   longpaths = true
//   autocrlf = false
//   eol = lf
//   checkStat = minimal
// [fetch]
//   negotiationAlgorithm = skipping
// [diff]
//   algorithm = histogram

// Write to file
await compiler.outputGitConfig('.gitconfig')

// Render as command-line arguments
const args = compiler.renderGitConfigToArgs()
console.log(args)
// Output: ['-c', 'core.longpaths=true', '-c', 'core.autocrlf=false', '-c', 'core.eol=lf', ...]

// Use in git commands
await compiler.runCommand(['git', ...args, 'clone', 'https://example.com/repo.git', 'dest'])
// Executes: git -c core.longpaths=true -c core.autocrlf=false ... clone https://example.com/repo.git dest
```

### Execute Shell Commands with Compiler.runCommand

Source: https://context7.com/jaidcompiles/brave/llms.txt

The `runCommand` method in the `Compiler` class enables the execution of shell commands. It supports environment variable inheritance from the compiler's configuration and allows for specifying the current working directory and additional environment variables for the command. Automatic error handling is included, throwing errors with exit codes upon failure.

```typescript
import {Compiler} from './lib/Compiler.ts'

const compiler = new Compiler({
  folder: '/tmp/build',
  environmentVariables: {
    NODE_ENV: 'production',
    DEBUG: 'false',
  },
})

// Run a simple command in the base folder
await compiler.runCommand(['git', 'status'])
// Executes in: /tmp/build
// Environment: includes NODE_ENV=production, DEBUG=false

// Run command in a subfolder
await compiler.runCommand(['npm', 'install'], {
  cwdExtra: ['git', 'brave', 'brave-browser'],
})
// Executes in: /tmp/build/git/brave/brave-browser

// Run with additional environment variables
await compiler.runCommand(['node', 'build.js'], {
  cwdExtra: 'scripts',
  env: {
    VERBOSE: 'true',
  },
})
// Executes in: /tmp/build/scripts
// Environment: includes NODE_ENV, DEBUG, VERBOSE

// Command failures throw errors with exit codes
try {
  await compiler.runCommand(['npm', 'test'])
} catch (error) {
  console.error('Command failed:', error.message)
  // Error message includes exit code and full command
}
```

--------------------------------

### Apply Regex Patches to Source Files with Compiler.applyPatch

Source: https://context7.com/jaidcompiles/brave/llms.txt

The `applyPatch` method in the `Compiler` class allows for regex-based find-and-replace operations on specified source files. It automatically verifies that patches have been applied, ensuring code integrity. This method is useful for tasks like disabling features, changing default settings, or renaming executables across a codebase.

```typescript
import {Compiler} from './lib/Compiler.ts'

const compiler = new Compiler({
  folder: '/tmp/brave-build',
})

// Disable a feature by changing a flag
await compiler.applyPatch({
  files: compiler.fromHere('git/brave/brave-browser/src/brave/components/brave_sync/features.cc'),
  from: /BASE_FEATURE\(\s*kBraveSync\s*,\s*base::FEATURE_ENABLED_BY_DEFAULT\s*\)/,
  to: 'BASE_FEATURE(kBraveSync, base::FEATURE_DISABLED_BY_DEFAULT)',
})
// Output: { patchedFiles: ['/tmp/brave-build/git/brave/brave-browser/src/brave/components/brave_sync/features.cc'] }

// Change a default setting
await compiler.applyPatch({
  files: compiler.fromHere('git/brave/brave-browser/src/brave/browser/brave_profile_prefs.cc'),
  from: /->RegisterBooleanPref\(kLocationBarIsWide,\s*false\)/,
  to: '->RegisterBooleanPref(kLocationBarIsWide, true)',
})

// Rename executable across multiple files
await compiler.applyPatch({
  files: compiler.fromHere('git/brave/brave-browser/src/chrome/BUILD.gn'),
  from: /_chrome_output_name = "chrome"/g,
  to: '_chrome_output_name = "jave"',
})
```

### Manage .env Files with Compiler.outputEnv() and patchEnvFile() in TypeScript

Source: https://context7.com/jaidcompiles/brave/llms.txt

The Compiler class provides methods to write and merge environment variables into .env files. `outputEnv` creates a new file, while `patchEnvFile` and `patchEnvFileWith` merge variables into existing files, preserving original values where possible. This is useful for build processes and configuration management.

```typescript
import {Compiler} from './lib/Compiler.ts'
import {EnvironmentVariables} from './lib/EnvironmentVariables.ts'

const compiler = new Compiler({
  folder: '/tmp/build',
})

// Set environment variables
compiler.environmentVariables.set('NODE_ENV', 'production')
compiler.environmentVariables.set('PORT', 8080)
compiler.environmentVariables.set('DEBUG', false)

// Write to new .env file
await compiler.outputEnv('.env')
// Creates /tmp/build/.env with content:
// NODE_ENV=production
// PORT=8080
// DEBUG=false

// Merge with existing .env file
await compiler.patchEnvFile('.env')
// Reads existing file, merges variables, preserves original values for unchanged keys

// Merge custom environment variables into file
const customEnv = new EnvironmentVariables()
customEnv.set('DATABASE_URL', 'postgresql://localhost/mydb')
customEnv.set('REDIS_URL', 'redis://localhost:6379')

await compiler.patchEnvFileWith('.env.local', customEnv)
// Updates /tmp/build/.env.local with database configuration
```

--------------------------------

### Manage Environment Variables with EnvironmentVariables Class

Source: https://context7.com/jaidcompiles/brave/llms.txt

The `EnvironmentVariables` class provides a robust way to manage environment variables. It supports type-safe parsing, manipulation of the PATH variable (prepending and adding items), and serialization/deserialization to/from `.env` file formats. It also facilitates merging different environment configurations and preparing environment variables for subprocess execution.

```typescript
import {EnvironmentVariables} from './lib/EnvironmentVariables.ts'

// Create from object
const env = EnvironmentVariables.fromObject({
  NODE_ENV: 'production',
  PORT: 3000,
  DEBUG: true,
  API_KEY: 'secret123',
})

// Parse values automatically
console.log(env.get('PORT')) // 3000 (number)
console.log(env.get('DEBUG')) // true (boolean)

// Manipulate PATH variable
env.prependPathItem('/usr/local/bin')
env.prependPathItem(['C:/tools/bin', 'C:/python39'])
env.addPathItem('/opt/bin')
console.log(env.getPath()) // ['C:/tools/bin', 'C:/python39', '/usr/local/bin', ..., '/opt/bin']

// Load from .env file
const fileEnv = await EnvironmentVariables.fromEnvFile('/path/to/.env')

// Parse .env contents
const contents = `
NODE_ENV=production
PORT=8080
DEBUG=true
API_KEY="quoted-value"
`
const parsedEnv = EnvironmentVariables.fromEnvContents(contents)

// Merge multiple environment sets
const defaultEnv = EnvironmentVariables.fromObject({ TIMEOUT: 5000 })
const overrideEnv = EnvironmentVariables.fromObject({ TIMEOUT: 10000 })
const merged = EnvironmentVariables.merge(defaultEnv, overrideEnv)
console.log(merged.get('TIMEOUT')) // 10000

// Export to .env format
const output = env.toEnvContents()
// Result:
// NODE_ENV=production
// PORT=3000
// DEBUG=true
// API_KEY=secret123

// Merge with process.env for subprocess
const finalEnv = env.toFinalStringObject()
// Contains all process.env variables plus custom ones
```

--------------------------------

### Create Type-Safe Options with makeOptions in TypeScript

Source: https://context7.com/jaidcompiles/brave/llms.txt

The makeOptions function generates type-safe option objects. It validates required fields and merges default values, ensuring configurations are complete and consistent. This function is useful for managing complex application settings.

```typescript
import {makeOptions} from './lib/package/make-options/src/index.ts'
import type {InputOptions} from './lib/package/make-options/src/index.ts'

type MyOptions = InputOptions<{
  required: {
    host: string
    port: number
  }
  optional: {
    timeout: number
    retry: boolean
  }
  defaults: {
    timeout: 5000
    retry: true
  }
}>

// Create options with validation
const options = makeOptions<MyOptions>(
  {
    host: 'localhost',
    port: 3000,
    timeout: 10000, // Override default
  },
  {
    requiredKeys: ['host', 'port'],
    defaultOptions: {
      timeout: 5000,
      retry: true,
    },
  }
)
// Result: { host: 'localhost', port: 3000, timeout: 10000, retry: true }

// Missing required fields throw errors
try {
  const invalid = makeOptions<MyOptions>(
    { host: 'localhost' }, // Missing 'port'
    { requiredKeys: ['host', 'port'] }
  )
} catch (error) {
  console.error(error.message)
  // "Required options are missing. Given keys: ['host']. Required keys: ['host', 'port']"
}

// With normalizations
type NormalizedOptions = InputOptions<{
  required: { path: string }
  normalizations: { path: string }
}>

const normalized = makeOptions<NormalizedOptions>(
  { path: 'some\windows\path' },
  {
    requiredKeys: ['path'],
    normalize: {
      path: (value) => (value as string).replace(/\\/g, '/'),
    },
  }
)
// Result: { path: 'some/windows/path' }
```

Source: https://context7.com/jaidcompiles/brave/llms.txt

This module provides utility functions for applying ANSI escape codes to terminal output, enabling colored and styled text for file paths, numbers, and commands. It enhances the readability and presentation of command-line interfaces.

```typescript
import * as ansi from './lib/package/ansi-sequences/src/index.ts'

// Format file paths with colors
console.log(ansi.file('/home/user/project/src/main.ts'))
// Output: /home/user/project/ (purple) + src/main.ts (orange)

console.log(ansi.folder('/usr/local/bin'))
// Output: /usr/local/bin (purple)

// Format numbers with colors
console.log(`Size: ${ansi.integer(1500000)}`) // 1,500,000 (cyan)
console.log(`Progress: ${ansi.percent(0.75, 1)}`) // 75.0% (cyan)
console.log(`Duration: ${ansi.ms(45500)}`) // 45s (cyan)
console.log(`File size: ${ansi.bytesShort(1536000)}`) // 1.54 MB (cyan)

// Format commands with proper escaping
console.log(ansi.command(['git', 'commit', '-m', 'Fix bug']))
// Output: git commit -m 'Fix bug' (styled)

console.log(ansi.command(['node', 'script.js', '--input', 'file with spaces.txt']))
// Output: node script.js --input 'file with spaces.txt'

// Create terminal links (VSCode/iTerm2/etc)
console.log(ansi.fileLink('/path/to/file.ts', 'Open file'))
// Output: Clickable link that opens file in editor

// Format file with size
const sizeInfo = await ansi.fileWithSize('/path/to/large-file.bin')
console.log(sizeInfo)
// Output: 15.3 MB /path/to/large-file.bin

// Custom formatting with template strings
console.log(ansi.make`Processed ${42} files in ${1234}ms`)
// Output: Processed 42 (cyan) files in 1234 (cyan)ms
