It would be nice to be able to offer suggestions for options that<br>
BuildSystem queries. For that, we need the set of command line options<br>
and the set of options that BuildSystem checked. We can get that by<br>
having RDict implement __missing__(self, key) to consult an immutable<br>
dict of the direct command line options and logging the query.<br></blockquote><div><br></div><div>Let me rephrase in order to see if I understand you. Suppose the code</div><div>checks for an option that has no value. We currently interactively prompt</div><div>for a value. You would also like us to suggest that one of the original options</div><div>which is close to this was misspelled. This is not hard. However,</div><div><br></div><div> 1) If the option has a default value, then we cannot see that it is missing,</div><div><br></div><div> 2) Those options should turn up in the unused list however</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
Is it feasible to check all the options by some point meaningfully<br>
sooner than the entire configure execution? It really sucks to wait<br>
many minutes for configure to complete only to find out that you<br>
misspelled an option. Getting that error message up-front would be a<br>
huge usability improvement.<br></blockquote><div><br></div><div>Right now, I am not sure how you would guarantee that the option would not</div><div>be used in the ensuing run.</div><div><br></div><div> Matt</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
