[Errno 13] Permission denied when trying to save()

[kompre]

Hi,

I'm trying to save a table generated with great-tables, but I get and [Errno 13] Permission denied (after several seconds of the command being issued).

I'm using poetry as package manager, and as web_driver I set edge because I have Brave instead of chrome.

I would like to use great-tables to produce tables for my quarto document. Since my output is mainly pdf and gt tables seems to loose some formatting going trough latex, I would like to insert the as image instead (maybe even pdfs?)

here a mwe with error attached:

# copied from the main site
from great_tables import GT
from great_tables.data import sp500

# Define the start and end dates for the data range
start_date = "2010-06-07"
end_date = "2010-06-14"

# Filter sp500 using Pandas to dates between `start_date` and `end_date`
sp500_mini = sp500[(sp500["date"] >= start_date) & (sp500["date"] <= end_date)]

# Create a gt table based on the `sp500_mini` table data
gt = (
    GT(sp500_mini)
    .tab_header(title="S&P 500", subtitle=f"{start_date} to {end_date}")
    .fmt_currency(columns=["open", "high", "low", "close"])
    .fmt_date(columns="date", date_style="wd_m_day_year")
    .fmt_number(columns="volume", compact=True)
    .cols_hide(columns="adj_close")
)


# trying to save
gt.save(file='test.png', web_driver='edge')

The error is the following:

@kompre, the code you provided appears to be working on version 0.6.0.

I confirm the code above works, as it save a test.png file. It is still not too much happy though:

• with web_driver='edge' the file is created but a warning appears (with firefox there is no warning):

[0522/125138.810:WARNING:edge_sandbox_win.cc(111)] AdjustConfigForVideoSuperResolutionSandboxedProcess: ignore error in getting DIR_COMPONENT_USER

DevTools listening on ws://127.0.0.1:62564/devtools/browser/510f480c-66a8-43ed-b63f-9bd2cba7fc03

• when I try to change extension to pdf or jpg I get another error and no file is saved:

# trying to save
gt.save(file='test.png', web_driver='firefox')

@kompre, I apologize, I forgot that I created a local patch on my computer. I submitted a PR (#352) to address this issue a few days ago, and hopefully it will be merged soon.
