Polars: settings not to display ellipsis

Polars chops some text instead of showing all text like the following

Link Name
https://… name1
https://… name2

I want Polars to show all text of Link Col

How can I do that?

You should change pl.Config() settings – pl.Config.set_fmt_str_lengths(n) (see doc)

import polars as pl
pl.Config.set_fmt_str_lengths(50)


df = pl.DataFrame({"n": [1], "link": ["https://stackoverflow.com/long/link"]})
print(df)

┌─────┬─────────────────────────────────────┐
│ n   ┆ link                                │
│ --- ┆ ---                                 │
│ i64 ┆ str                                 │

If you just want to check, how new table view looks like, you can use with pl.Config() (this will not affect to next table’s printings). Also pl.Config.set_tbl_width_chars(n) allows to set total width of table. For instance:

with pl.Config() as cfg:
    cfg.set_tbl_width_chars(15) # total width of table
    cfg.set_fmt_str_lengths(50)
    print(df)

┌─────┬───────┐
│ n   ┆ link  │
│ --- ┆ ---   │
│ i64 ┆ str   │
╞═════╪═══════╡
│ 1   ┆ https │

│     ┆ ackov │

│     ┆ w.com │
│     ┆ /long │
│     ┆ /link │
└─────┴───────┘
