[BUG] Table output columns break when content exceeds terminal width

[nadavs123]

Bug Description

Description

When print_output_format renders a table with show_headers=True and the total row width exceeds the terminal width, columns are pushed off-screen and wrap to the next line. This makes the output appear as if columns have disappeared: headers show on one line, some values appear on the next line, and the table alignment is completely lost.

fabric-cli version

1.3.1

Python version

Python 3.12.10

Operating System

Windows

CLI Mode

Interactive mode

Authentication Method

Interactive browser login

Steps to Reproduce

1. Use a command like ls or find that supports table rendering
2. Get a response with long values

Expected Behavior

Table columns should fit within the terminal width. Long values in columns should be truncated with ... to prevent the table from exceeding the terminal width.

Actual Behavior

When a page contains column with long values, the table row exceeds the terminal width. This causes:

• Headers are pushed to the far right edge or off-screen
• Values to wrap to a second line
• The table to appear as if columns are missing

Additional Context

This affects all commands that use print_output_format with show_headers=True.

Possible Solution

• The find command already truncates description in compact mode using shutil.get_terminal_size(). A similar approach could be applied to other columns like name.
• A more robust fix would be terminal-width-aware column sizing in the shared table renderer (_print_output_format_result_text).

AI Assessment: Potential Bug

The described rendering issue in interactive mode stems from the table output not being aware of terminal width constraints, resulting in misaligned columns and wrapped rows. This behavior deviates from established CLI conventions and the expected formatting described in the documentation, where output should remain readable and columns should not disappear when terminal space is limited (output format reference). The "find" command logic cited indicates that the codebase already considers terminal width for some columns but not consistently for all tabular outputs.

The impact is significant: users may misinterpret output, miss critical information, or perceive some table values as missing. This is especially problematic across all interactive commands employing print_output_format with headers. Per POSIX and GNU CLI standards, output should adjust for the local environment, either by truncation or by sensible wrapping.

The suggested solution of using terminal-width-aware column sizing in the table renderer is appropriate and aligns with typical CLI best practices for output handling. Implementation should ensure column fitting and truncation with ellipsis when space is insufficient.
