scanner: compute token line/column lazily on errors The scanner functions are hot, and the line/column location tracking is quite expensive. We only use it for errors, which don't need to be fast, because we bail if there are too many; and for warnings, which are usually not shown by default. So only keep the token start pos, and compute the line/column lazily from that. This will also allow some further improvements ahead. bench/rulescomp before: compiled 1000 keymaps in 1.669028s after: compiled 1000 keymaps in 1.550411s bench/compose: before: compiled 1000 compose tables in 2.145217s after: compiled 1000 compose tables in 2.016044s Signed-off-by: Ran Benita <ran@unusedvar.com>
