Replace A Range Of Lines (LCC.web_file.set_range_lines)

Signature

ok, replaced_or_err = LCC.web_file.set_range_lines(path, start_line, lines, timeout?)

Parameters

• path
  String. File path.
• start_line
  Number. Starting line index; positive numbers start at 1, negative values count from the end (-1 is the last line), and 0 means after the end.
• lines
  Table. Array of new line strings.
• timeout
  Number, optional. Request timeout in seconds, default 60.

Returns

• ok
  Boolean. true on success, false on failure.
• replaced_or_err
  Table or string. Replaced original lines on success, or the error description on failure.

Notes

Overwrites multiple lines at once starting from the given position.
See the parameter description above for line-number rules.
When the target position is beyond the current end, blank lines are padded automatically.
Returns {} when no existing lines were replaced.
The returned old content is useful for auditing or undo flows.

Example

local ok, old_lines_or_err = LCC.web_file.set_range_lines("/config/list.txt", 2, {"Beta", "Gamma"})
if ok then
    print("Original:", table.concat(old_lines_or_err, ","))
end
