denops-author

Use this skill to ground Denops implementation details in lambdalisue's Denops plugins only.

Quick reference (examples-based patterns)

• Buffer vars: use vars.b.get and error if missing. Source: denops/gin/command/blame/buffer_utils.ts https://raw.githubusercontent.com/lambdalisue/vim-gin/main/denops/gin/command/blame/buffer_utils.ts
• Buffer-local mappings: b:did_ftplugin guard + setlocal + <Plug> indirection + g: flag to disable. Source: ftplugin/gin-status.vim https://raw.githubusercontent.com/lambdalisue/vim-gin/main/ftplugin/gin-status.vim
• g:/env vars batching: batch.gather + batch.batch to reduce RPCs. Source: denops/askpass/main.ts https://raw.githubusercontent.com/lambdalisue/vim-askpass/main/denops/askpass/main.ts
• g: defaults: define helper with get(g:, name, default) at plugin entry. Source: plugin/kensaku.vim https://raw.githubusercontent.com/lambdalisue/vim-kensaku/main/plugin/kensaku.vim
• Batch config read: collect to read v: and g: at once; coerce booleans. Source: denops/guise/main.ts https://raw.githubusercontent.com/lambdalisue/vim-guise/main/denops/guise/main.ts
• DenopsPluginPost hook: define commands that call denops#notify, then wire autocmd. Source: plugin/chameleon.vim https://raw.githubusercontent.com/lambdalisue/vim-chameleon/main/plugin/chameleon.vim
• Interrupt/cleanup: use denops.interrupted and return Symbol.asyncDispose. Source: denops/chameleon/main.ts https://raw.githubusercontent.com/lambdalisue/vim-chameleon/main/denops/chameleon/main.ts
• Collect + fn wrappers: batch multiple fn.* calls with collect. Source: denops/initial/main.ts https://raw.githubusercontent.com/lambdalisue/vim-initial/main/denops/initial/main.ts
• Abort signal composition: combine denops.interrupted with local AbortController. Source: denops/refine/main.ts https://raw.githubusercontent.com/lambdalisue/vim-refine/main/denops/refine/main.ts
• Early exit + autocmd setup: check env/args and finish, then augroup + autocmd. Source: plugin/guise.vim https://raw.githubusercontent.com/lambdalisue/vim-guise/main/plugin/guise.vim

Workflow

1. Identify the task type (buffer vars, mappings, global/env vars, dispatcher/API boundary).
2. Open references/denops-author-examples.md and extract the closest matching example.
3. Follow the same structure and naming conventions; adapt to the target plugin but keep the pattern.
4. When responding, cite the example file path and explain the rationale briefly.

Notes

• Keep Vimscript responsibilities minimal; push logic into Denops TypeScript where possible.
• Prefer @denops/std modules for Vim interactions instead of raw denops.call when an example shows that pattern.
• Use buffer-local mappings and <Plug> indirections as shown in the references.
