General Characteristics
Server Properties
Some languages persist a cache to disk. Subsequent startups will be faster
Each language is handled by its own independent process
Requests are handled asynchronously
File Symbols
All languages use
ast-grep
for file symbol extraction:
Consistent < 50ms response time across languages and file sizes
We control these rules, if you see something off, let us know
Language-Specific Characteristics
C/C++ (
clangd
)
Performance
Long indexing time to startup
Persists cache to disk
Consistent memory usage (~100 MB)
Fast request response
Known Issues
May require restarting
lsproxy
to initialize cache files. We are working on this:
