" LLM-based text completion using llama.cpp
"
" requires:
"
"   - neovim or vim
"   - curl
"   - llama.cpp server instance
"   - FIM-compatible model
"
" sample config:
"
"   - Tab       - accept the current suggestion
"   - Shift+Tab - accept just the first line of the suggestion
"   - Ctrl+F    - toggle FIM completion manually
"
" make symlink or copy this file to ~/.config/nvim/autoload/llama.vim
"
" start the llama.cpp server with a FIM-compatible model. for example:
"
"   $ llama-server -m {model.gguf} --port 8012 -ngl 99 -fa --ubatch-size 512 --batch-size 1024 --cache-reuse 256
"
"   --batch-size [512, model max context]
"
"     adjust the batch size to control how much of the provided local context will be used during the inference
"     lower values will use smaller part of the context around the cursor, which will result in faster processing
"
"   --ubatch-size [64, 2048]
"
"     chunks the batch into smaller chunks for faster processing
"     depends on the specific hardware. use llama-bench to profile and determine the best size
"
"   --cache-reuse (ge:llama_config.n_predict, 1024]
"
"     this should be either 0 (disabled) or strictly larger than g:llama_config.n_predict
"     using non-zero value enables context reuse on the server side which dramatically improves the performance at
"     large contexts. a value of 256 should be good for all cases
"
" run this once to initialise llama.vim:
"
"   :call llama#init()
"
" more info: https://github.com/ggml-org/llama.cpp/pull/9787

highlight llama_hl_info guifg=#77ff2f ctermfg=119

" general parameters:
"
"   endpoint:         llama.cpp server endpoint
"   n_prefix:         number of lines before the cursor location to include in the local prefix
"   n_suffix:         number of lines after  the cursor location to include in the local suffix
"   n_predict:        max number of tokens to predict
"   t_max_prompt_ms:  max allotted time for the prompt processing (TODO: not yet supported)
"   t_max_predict_ms: max allotted time for the prediction
"   show_info:        show extra info about the inference (0 - disabled, 1 - statusline, 2 - inline)
"   auto_fim:         trigger FIM completion automatically on cursor movement
"   max_line_suffix:  do not auto-trigger FIM completion if there are more than this number of characters to the right of the cursor
"
" ring buffer of chunks, accumulated with time upon:
"
"  - completion request
"  - yank
"  - entering a buffer
"  - leaving a buffer
"  - writing a file
"
" parameters for the ring-buffer with extra context:
"
"   ring_n_chunks:    max number of chunks to pass as extra context to the server (0 to disable)
"   ring_chunk_size:  max size of the chunks (in number of lines)
"                     note: adjust these numbers so that you don't overrun your context
"                           at ring_n_chunks = 64 and ring_chunk_size = 64 you need ~32k context
"   ring_scope:       the range around the cursor position (in number of lines) for gathering chunks after FIM
"   ring_update_ms:   how often to process queued chunks in normal mode
"
