Syntax
bool translator:chdir ( string dirPath )
Arguments
- dirPath: a path to a directory that should be made current directory
Returns
This function returns true if the directory pointed at by dirPath is an existing directory and can be accessed by the translator, false otherwise.

ClientThis snippet creates a simple command-based filesystem explorer.
-- Create a generic FileSystem translator.
local cmdTranslator = fileCreateTranslator( "/" );
-- Set up some commands.
addCommandHandler( "chdir",
function(...)
local myPath = table.concat( { ... }, " " );
cmdTranslator:chdir( myPath );
end
);
addCommandHandler( "dir",
function()
-- todo: resolve a path given as arguments.
local myEntries = {};
local function itemIterator( path )
table.insert( myEntries, cmdTranslator:relPath( path ) );
end
cmdTranslator:scanDirEx( "/", "*", itemIterator, itemIterator, false );
-- Output the filesystem entries to the chatbox.
for m,n in ipairs( myEntries ) do
outputChatBox( n );
end
-- todo: print statistics (file size, number of files, number of directories, ...)
end
);
