R: Enrich flattened parse table

enrich_terminals {styler} | R Documentation

## Enrich flattened parse table

### Description

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.

### Usage

    enrich_terminals(flattened_pd, use_raw_indention = FALSE)

### Arguments

`flattened_pd` | A nested parse table that was turned into a flat parse table using `extract_terminals()`.
`use_raw_indention` | Boolean indicating whether or not the raw indention should be used.

### Details

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.
