How would you improve Rich?
RichHandler formats messages in columns, thus all the message lines after the 1st one have a huge margin on both sides (left: time and level, right: source file:line) and are wrapped.
I would like the subsequent lines (2nd and ff) to be formatted as is, no colors, no columns, no wrapping.
What problem does it solve for you?
I often print pandas data frames on the subsequent lines, so the width real estate is critical for me: I don't want any wrapping whatsoever.
Here is the code:
def df2str(df:pd.DataFrame) -> str:
"""Pretty string representation of the DataFrame.
Ensure that no rows or columns are omitted."""
rows,cols = df.shape
with pd.option_context("display.width",10000,
"display.max_columns",cols,
"display.max_rows",rows):
return str(df)
mylogger.info("this is a wide data frame:\n%s", df2str(pd.DataFrame({f"c{c}":range(5) for c in range(25)})))
without RichHandler I get
