Enhance Tab Completion to Work with Any Character

Enhance Tab Completion to Work with Any Character

Current Behavior

Currently, the tab completion feature only works after typing the '@' character. When a user types '@' and presses the Tab key, an autocomplete window pops up showing file suggestions.

Desired Behavior

Tab completion should work with any character sequence, not just after '@'. A user should be able to type any character(s) and press Tab to see matching completions.

For example:

• Type f and press Tab → Should show completions for files beginning with 'f'
• Type fo and press Tab → Should show completions for files beginning with 'fo', like 'foo'

Technical Details

The current implementation filters completions based on the '@' character in SearchTerm::process() method:

// In crates/forge_main/src/completer/search_term.rs
pub fn process(&self) -> Option<TermResult<'_>> {
    // Get all the indexes of the '@' chars
    // Get all chars between @ and the cursor
    let term = self
        .line
        .chars()
        .enumerate()
        .filter(|(_, c)| *c == '@')  // This specifically looks for the '@' character
        .map(|(i, _)| i)
        .filter(|at| *at < self.position)
        .max_by(|a, b| a.cmp(b))
        .map(|at| TermResult {
            span: Span::new(at + 1, self.position),
            term: &self.line[at + 1..self.position],
        })
        .filter(|s| !s.term.contains(" "));

    term
}

The InputCompleter uses this SearchTerm class to determine what to complete:

// In crates/forge_main/src/completer/input_completer.rs
if let Some(query) = SearchTerm::new(line, pos).process() {
    let files = self.walker.get_blocking().unwrap_or_default();
    files
        .into_iter()
        .filter(|file| !file.is_dir())
        .filter_map(|file| {
            // Filtering logic
        })
        .collect()
} else {
    vec![]
}

Implementation Suggestions

1. Modify the SearchTerm::process() method to work with any character, not just '@'.
2. Implement word boundary detection to determine what the user is trying to complete.
3. Update the tab completion logic in editor.rs if necessary.

Acceptance Criteria

• User can type any character and press Tab to see file completions
• Completions are contextual to what has been typed
• Existing functionality (like command completion) is preserved
• Test cases are updated to reflect the new behavior

Additional Notes

This enhancement will improve the user experience by making completion more intuitive and consistent with standard CLI behavior.
