# Define document loaders to control how RAG and `.file`/`--file` load files of specific formats.
document_loaders:
  # You can add custom loaders using the following syntax:
  #   <file-extension>: <command-to-load-the-file>
  # Note: Use `$1` for input file and `$2` for output file. If `$2` is omitted, use stdout as output.
  pdf: 'pdftotext $1 -'                         # Load .pdf file, see https://poppler.freedesktop.org
  docx: 'pandoc --to plain $1'                  # Load .docx file
  # xlsx: 'ssconvert $1 $2'                     # Load .xlsx file

New REPL Commands

.rag                     Init or use the RAG
.info rag                View RAG info
.rebuild rag             Rebuild the RAG to sync document changes
.exit rag                Leave the RAG

.agent                   Use a agent
.info agent              View agent info
.starter                 Use the conversation starter

.continue                Continue the response
.regenerate              Regenerate the last response

New CLI Options

  -R, --rag <RAG>            Start a RAG

Break Changing
Some client fields have changed
clients:
  - name: myclient
    patches: 
      <regex>:
-       request_body:
+       chat_completions_body:           
    models:
    - name: mymodel
      max_output_tokens: 4096
-     pass_max_tokens: true
+     require_max_tokens: true

The way to identify dangerous functions has changed
Previous we treats function name that starts with may_ as execute type (dangerously). This method requires modifying function names, which is inflexible.
Now we makes it configurable. In config.yaml, you can now define which functions are considered dangerous and require user confirmation .
dangerously_functions_filter: 'execute_.*'
