history

Project history and usage

merman-cli is the command-line wrapper around Merman, an independent Rust implementation of Mermaid parsing, layout, and rendering. The project describes itself as Mermaid.js, but headless, in Rust, and notes that it is not affiliated with or endorsed by the Mermaid project. Its stated compatibility target is a pinned Mermaid release, with parity checked through semantic, layout, and SVG baselines.

Project history

Its niche is the browserless side of Mermaid rendering. Instead of launching Chromium or a JavaScript runtime, Merman exposes Rust crates for parsing, semantic JSON, typed render models, SVG, raster output, and terminal-oriented ASCII or Unicode output. The CLI packages those capabilities for users who want Mermaid-style diagrams in build scripts, terminals, or Rust-heavy environments where headless browser dependencies are undesirable.

How it is used

Because the public footprint is still mostly the project README, docs.rs, and crates packaging, there is limited independent history to report. The strongest sourced context is technical: it is a parity-focused compatibility implementation by Mermaid users, distributed as Rust crates and as a Homebrew CLI.

security posture

No protected-tool coverage found yet

No matching local secret-handling manifest was found for merman-cli. Package metadata is still published here so future coverage has a stable package URL.

Install behavior

  • No Homebrew post-install hook is recorded in formula metadata.
  • Homebrew bottle metadata is available for 6 platform targets.
  • Build metadata lists 1 build dependencies.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
