Script_lua is a basic example plugin. This wiki page is intended as a walkthrough of the code in order to help you better understand the SDK.
Contents
Functionality
This plugin serves as a Lua script interpreter.
Code Walkthrough
Declarations
typedef struct st_IntrInstance {
ILxScriptID script; // Script being executed.
ILxMonitorID monitor; // Progress monitor used by lxmon??? functions.
int askedForMonitor; // True if we asked for the monitor.
LxResult rc; // Result code from the most recently executed/queried command.
int tracing; // 1 if tracing is active, 0 if inactive.
int execFlags; // Flags provided by the caller of Run() and used for command execution.
CLxUser_LogEntry log; // For logging data
int queryAnglesAsDegrees; // True if queried angles should be returned in degrees instead of radians.
} IntrInstance;
This is a struct that defines certain objects and constants that will be used by the plugin.
extern "C" int l_lxout(lua_State *L); extern "C" int l_lx(lua_State *L); extern "C" int l_lxq(lua_State *L); extern "C" int l_lxqt(lua_State *L); extern "C" int l_lxeval(lua_State *L); extern "C" int l_lxok(lua_State *L); extern "C" int l_lxres(lua_State *L); extern "C" int l_lxtrace(lua_State *L); extern "C" int l_lxoption(lua_State *L); extern "C" int l_lxsetOption(lua_State *L); extern "C" int l_lxmonInit(lua_State *L); extern "C" int l_lxmonStep(lua_State *L);
Declaration of functions that will be used by the plugin.
extern "C" {
ILxScriptSysServiceID scriptSrv; /* Script system service; common to all instances */
ILxStdDialogServiceID dlgSrv; /* Standard dialog service; common to all instances */
IntrInstance intrStack[ MAX_STACK ]; /* Interpreter stack; allows scripts to execute other scripts */
int intrTop = -1; /* The current script being executed as an index into interStack */
IntrInstance *intrCur = NULL; /* The same as &intrStack[ intrTop ], or NULL if intrTop is -1 */
}
Here we declare a variety of scripts and services that will be used below. "extern" indicates that the objects inside have already been defined elsewhere so the compiler won't complain.
Class Declarations
class CLuaInterpreter : public CLxImpl_TextScriptInterpreter
{
CLxUser_LogService logSvc;
CLxUser_CommandService cmdSvc;
CLxUser_ValueService valueSvc;
public:
virtual ~CLuaInterpreter () {}
virtual LxResult tsi_ValidateFileType (
ILxUnknownID scriptObj,
const char *firstLine) LXx_OVERRIDE;
virtual LxResult tsi_Run (
ILxUnknownID scriptObj,
int execFlags,
const char *args,
ILxUnknownID messObj) LXx_OVERRIDE;
void Init ();
void Kill ();
static LXtTagInfoDesc descInfo[];
private:
lua_State *L;
};
This class is intended to take a lua script and interpret it, so we need it to be a modified text editor. To this end, we inherit from CLxImpl_TextScriptInterpreter.
Server Tags
The tags here indicate that CLuaInterpreter has the name Lua Scripts and takes files with the .lua extension.
Initialize
void
initialize ()
{
LXx_ADD_SERVER (TextScriptInterpreter, CLuaInterpreter, "lua");
}
This initialize function exports one server of the type TextScriptInterpreter that is dependent on the class CLuaInterpreter and has the name lua.
Implementations
static void
AddLogStringEntry (
CLxLoc_LogEntry &parent,
const char *s,
LxResult code,
int persist,
CLxLoc_LogEntry &entry)
{
if (logSrv->NewEntry (code, s, entry)) {
parent.AddEntry (entry);
}
}

CLxLoc_LogEntry &parent,
const char *s,
LxResult code,

CLxLoc_LogEntry entry;
AddLogStringEntry (parent, s, code, persist, entry);
}
Adding a log entry to a parent, for clients with no need for the entry.
void

int

At some point in the future, lxq() needs to use the raw string conversion feature to ensure that the values that are queried are the same kinds of values that get passed to commands.
int

lxqt(): Query a toggle command's toggle argument. Returns the query state on success (1 or 0), or 0 on failure.
int

Return true if the last command executed/queried successfully.

When activated, lx() and lxq() data is output to the event log. If no args are passed in, this returns if tracing is active or not.

Step the progress bar. Increment the progress bar by n steps, or 1 step if no steps are provided. This always returns true unless the user aborts, in which case it returns false.
