parseNamespaceFile() doesn't seem to detect misspelled directives. Looking
at its code I see
switch(as.character(e[[1L]]),
<lots of args omitted here>,
stop(gettextf("unknown namespace directive: %s",
deparse(e)), call. = FALSE, domain = NA))
but this doesn't seem to function as I expect, viz. to stop with an error
if I type a wrong directive.
Details:
# create dummy NAMESPACE file with two bad / one good directives
cat("blah( nada )\nblee( nil )\nexport( outDS )\n",file="NAMESPACE")
readLines("NAMESPACE")
[1] "blah( nada )" "blee( nil )" "export( outDS )"
parseNamespaceFile("",".") # now parse it
$imports
list()
$exports
[1] "outDS"
$exportPatterns
character(0)
$importClasses
list()
$importMethods
list()
$exportClasses
character(0)
$exportMethods
character(0)
$exportClassPatterns
character(0)
$dynlibs
character(0)
$nativeRoutines
list()
$S3methods
[,1] [,2] [,3]
So, it picked up 'export' and ignored the other two lines.
