Thanks Ralf. Renaming the library got past that library load error. However,
the view page is listing other errors, which may hint at other mistakes I’ve
made.
The key page markup is below - I’d appreciate any advice.
**********************************************
The testlib.lc library content is just the prototype with a “Hello World” test
return in the example handler...
<?rev
put gBASEPATH into gBASEPATH
if gBASEPATH is "gBASEPATH" then
put "No direct script access allowed."
exit to top
end if
# LOGGING
rigLogMessage "debug", "Your Library Loaded"
# DECLARE LOCAL VARIABLES
# PROTOTYPE OF THE FOLLOWING HANDLER NAME: rigRunInitialLibrarynameConfig
command rigRunInitialYourlibConfig
--Run initial configuration procedures. Don't remove this handler, even
if it does nothing.
end rigRunInitialYourlibConfig
command someHandler
return "Hello World"
end someHandler
************************************************
The home.lc controller seeks to load the testlib library & add the "Hello
World" return value to the global data array…
<?rev
# PUT ALL HANDLER NAMES WHICH ARE LIKELY TO SERVE AS URI SEGMENTS
# INTO THE GLOBAL gControllerHandlers AS A COMMA SEPARATED LIST
put "home,index" into gControllerHandlers
# WRITE INITIAL STATEMENTS INTO THE CONTROLLER HANDLER
command home
# SAVE PAGE IN CACHE DIRECTORY WITH AN EXPIRATION TIME OF n MINUTES
# NOTE: THIS IS NOT MANDATORY, DON'T USE CACHING WHILE WORKING ON THE
CODE,
# OTHERWISE YOU WON'T SEE YOUR CHANGES IMMEDIATELY
rigOutputCache 3
rigLoaderLoadLibrary "testlib"
put somehandler() into gData["testlib"]
end home
# THIS COMMAND WILL BE CALLED IF NONE IS SPECIFIED IN THE URI
command index
# REMEMBER TO PUT ALL THE VARIABLES TO BE MERGED WITH VIEWS INTO THE
ARRAY VARIABLE gData
# SET PAGE TITLE
put "Welcome to the Knowledge Base" into gData["pageTitle"]
put RIVERSION && RISTATE into gData["revIgniterVersion"]
put the version into gData["serverVersion"]
# LOAD THE VIEW FILE
get rigLoadView("home")
end index
****************************************
The home view is a copy of the welcome.lc view with one line added to show the
"Hello World” test
<p>[[gData["testlib"] ]]</p>
****************************************
The inline error list override of the view page may provide some clues (paths
truncated with ‘…' ) ...
