Enrich flattened parse table
Enriches a flattened parse table with terminals only. In particular, it is possible to compute the exact position a token will have (line and column) when it will be serialized.
enrich_terminals(flattened_pd, use_raw_indention = FALSE)
flattened_pd |
A nested parse table that was turned into a flat parse
table using |
use_raw_indention |
Boolean indicating whether or not the raw indention should be used. |
Since we have only terminal tokens now, the line on which a token starts we
also be the line on which it ends. We call line1 the line on which the
token starts. line1 has the same meaning as line1 that can be found in a
flat parse table (see tokenize()), just that the line1 created by
enrich_terminals() is the updated version of the former line1. The same
applies for col1 and col2. Note that this function does remove the
columns indent and spaces. All information of the former is stored in
lag_spaces now. The later was removed because it is redundant after adding
the column lag_spaces, which is more convenient to work with, in particular
when serializing the parse table.
