Re: [Sablevm-developer] Re: Config File Parsing

[Etienne M. G. <eg...@j-...>]

I forgot something: I am already using popt.  I now remember that it can
parse arbitrary strings in argv[] style arrays.

A very simple program could read options from a configuration file,
strip leading/trailing space characters (at the line beginning/end, and
around the first "=" character) then add a "--" prefix, then store the
result in an array of strings, then simply add to this array the strings
of argv[].  As usual, empty lines (after stripping) and comment lines
(starting with #) would be ignored.  Line continuation support would be
nice to have, too;-)

i.e.:

file content
------------
# comment
  boot-class-path = /usr/share/sablepath/classes
  boot-library-path \
    = /usr/share/sablepath/lib
...

converted into:

"--boot-class-path=/usr/share/sablepath/classes"
"--boot-library-path=/usr/share/sablepath/lib"


The nice thing, with this approach, is that we would automatically get
popt's error messages for invalid options (and optinally option
aliasing, too!)

This would probably be the best solution, as it fits nicely with the
current command line parsing code.
