Parser Architecture 1.0 – What didn’t work
well
§Performance
4Assumed parse times
would be quick, < 1 sec
•Finding parse times
usually in 2-4 second range
4Index takes a lot of
time, memory, and CPU power to generate
4Content assist times
out regularly
§Hard to provide accurate
results consistently
4F3 and content assist
often produce no results
4Need for accurate
ScannerInfo often hard to satisfy
§Scalability to large
projects
4Problems only worsen
when project grows
4Index times longer than
already long build times
4ScannerInfo different
for different files in project
