<p>I would just add a function<br>
<br>
setAlexUserState :: AlexUserState -> Alex ()<br>
setAlexUserState = ...<br>
<br>
and then write another<br>
<br>
run :: AlexUserState -> Alex ()<br>
run st = do<br>
setAlexUserState st<br>
alexMonadScan<br>

<p class="MsoNormal"><span lang="EN-US">I have a Alex lexer with
wrapper "monadUserState-bytestring". The AlexUserState =
AlexUserState {sheetNames:: {String], currSheet:: Int}. The
lexer should check whether a found sheetname is in
sheetNames. The sheetNames from AlexUserState come from
outside. I want to invoke the lexer many times with
different AlexUserStates. Therefore the alexInitUserState
function is not what I want. I’de like to initialize the
AlexUserState while starting the lexer, i.e. as a parameter
to runAlex. Can that be done?<o:p></o:p></span></p>
