 @title Diffusion User Guide: Symbol Indexes
 @group userguide
 
 Guide to configuring and using the symbol index.
 
 = Overview =
 
 Phabricator can maintain a symbol index, which keeps track of where classes
 and functions are defined in the codebase. Once you set up indexing, you can
 use the index to do things like:
 
   - jump to symbol definitions from Differential code reviews and Diffusion
     code browsing by ctrl-clicking (cmd-click on Mac) symbols
   - search for symbols from the quick-search
   - let the IRC bot answer questions like "Where is SomeClass?"
 
 NOTE: Because this feature depends on the syntax highlighter, it will work
 better for some languages than others. It currently works fairly well for PHP,
 but your mileage may vary for other languages.
 
 = Populating the Index =
 
 To populate the index, you need to write a script which identifies symbols in
 your codebase and set up a cronjob which pipes its output to:
 
   ./scripts/symbols/import_repository_symbols.php
 
 Phabricator includes a script which can identify symbols in PHP projects:
 
   ./scripts/symbols/generate_php_symbols.php
 
 Phabricator also includes a script which can identify symbols in any
 programming language that has classes and/or functions, and is supported by
 Exuberant Ctags (http://ctags.sourceforge.net):
 
   ./scripts/symbols/generate_ctags_symbols.php
 
 If you want to identify symbols from another language, you need to write a
 script which can export them (for example, maybe by parsing a `ctags` file).
 
 The output format of the script should be one symbol per line:
 
   <context> <name> <type> <lang> <line> <path>
 
 For example:
 
   ExampleClass exampleMethod function php 13 /src/classes/ExampleClass.php
 
 Context is, broadly speaking, the scope or namespace where the symbol is
 defined. For object-oriented languages, this is probably a class name. The
 symbols with that context are class constants, methods, properties, nested
 classes, etc. When printing symbols without a context (those that are defined
 globally, for instance), the `<context>` field should be empty (that is, the
 line should start with a space).
 
 Your script should enumerate all the symbols in your project, and provide paths
 from the project root (where ".arcconfig" is) beginning with a "/".
 
 You can look at `generate_php_symbols.php` for an example of how you might
 write such a script, and run this command to see its output:
 
   $ cd phabricator/
   $ find . -type f -name '*.php' | ./scripts/symbols/generate_php_symbols.php
 
 To actually build the symbol index, pipe this data to the
 `import_repository_symbols.php` script, providing the repository callsign:
 
-  $ ./scripts/symbols/import_repository_symbols.php rREPO < symbols_data
+  $ ./scripts/symbols/import_repository_symbols.php REPO < symbols_data
 
 Then just set up a cronjob to run that however often you like.
 
 You can test that the import worked by querying for symbols using the Conduit
 method `diffusion.findsymbols`. Some features (like that method, and the
 IRC bot integration) will start working immediately. Others will require more
 configuration.
 
 = Advanced Configuration =
 
 You can configure some more options by going to {nav Diffusion > (Select
  repository) > Edit Repository > Edit Symbols}, and filling out these fields:
 
   - **Indexed Languages**: Fill in all the languages you've built indexes for.
     You can leave this blank for "All languages".
   - **Uses Symbols From**: If this project depends on other repositories, add
     the other repositories which symbols should be looked for here. For example,
     Phabricator lists "Arcanist" and "libphutil" because it uses classes and
     functions from these repositories.
 
 == External Symbols ==
 
 By @{article:Adding New Classes}, you can teach Phabricator
 about symbols from the outside world.
 Extend @{class:DiffusionExternalSymbolsSource}; Once loaded, your new
 implementation will be used any time a symbol is queried.
 
 See @{class:DiffusionPhpExternalSymbolsSource} and
 @{class:DiffusionPythonExternalSymbolsSource} for example implementations.
