New Features of Eli Version 4.8
 
The format of a processor's command line can be specified in
clp (see Command Line Processor of Command Line Processor).
In addition to defining options and parameters, the designer can specify
the form of an error report to be used when a file appearing on the command
line cannot be opened.
In earlier versions of Eli, this message was only written when the
processor could not open its primary input file.
As a part of the refactoring to support foreign parsers, we defined a
routine
ClpOpenError to output the report on request
(see Reporting open errors of Command Line Processor).
This report will be automatically made if the processor cannot open the
file specified on the command line as its primary source of data
(see Input parameters of Command Line Processor).
User code can also make the report if it encounters an error while opening
an arbitrary file.
