## What it is
neocomplcache is a Vim plugin providing an automatic keyword completion system that caches keywords from the current buffer. Development has finished; the author recommends migrating to its successor, ddc.vim.

## Use cases
- auto-complete words while typing in vim
- keyword completion from current buffer in vim
- filename completion in vim
- omni completion enhancement for vim
- smart case and camel case completion in vim
- vim plugin for code autocompletion without language server

## When to choose
- you use an old Vim version without Lua support where neocomplete won't work
- you need a pure Vim Script completion plugin with no external dependencies
- you maintain a legacy Vim setup already built around neocomplcache

## When to avoid
- you use Vim 7.3.885+ with Lua (use neocomplete instead)
- you want modern LSP-based completion (use ddc.vim, coc.nvim, or nvim-cmp)
- you need new features or active development

## Facets
- artifact type: plugin
- maturity: maintenance
- function: editor
- domain: text-editors, developer-tools
- platform: editor-plugin, cross-platform
- tags: vim, autocompletion, vim-script, deprecated, keyword-completion
