It reads an HTTP request, including headers and body, and emits an equivalent curl command line. ### Project history The official repository was created under the curl GitHub organization in August 2017. Its README defines the project narrowly: given a set of HTTP request headers, h2c outputs the curl command line needed to generate that request. ### Adoption history Adoption is intentionally modest and developer-tool focused. The project has an official curl.se web surface plus a Homebrew formula, making it easy for curl users to install when they need to translate captured HTTP requests into repeatable CLI invocations. ### How it is used The README examples cover HTTP/1.1 and HTTP/2 requests, PUT bodies, multipart form uploads, cookies, user agents, and Basic authentication. The tool is useful when moving from a raw request captured in logs, browser tools, or documentation into a shell-friendly curl command. ### Why package nerds care h2c is package-nerd smallness in pure form: a single-purpose converter maintained near curl, valuable because it removes quoting and flag-selection friction without becoming a general HTTP client. ### Timeline - 2017: Repository created under the curl organization. - 2017: README documented conversion of raw HTTP requests into curl commands. - 2022: Repository metadata showed continued maintenance activity through mid-2022. ### Related projects - h2c is directly related to curl and to workflows that capture raw HTTP requests from browsers, proxies, examples, or tests and replay them from the command line. ### Sources - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** h2c - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [ain](https://www.automicvault.com/pkg/brew/ain/) - Shares av.db curated category or tags: cli, curl, developer-tools, http. - [httpstat](https://www.automicvault.com/pkg/brew/httpstat/) - Shares av.db curated category or tags: cli, curl, developer-tools, http. - [hurl](https://www.automicvault.com/pkg/brew/hurl/) - Shares av.db curated category or tags: cli, curl, developer-tools, http. - [ali](https://www.automicvault.com/pkg/brew/ali/) - Shares av.db curated category or tags: cli, developer-tools, http. - [ansifilter](https://www.automicvault.com/pkg/brew/ansifilter/) - Shares av.db curated category or tags: cli, converter, developer-tools. - [apib](https://www.automicvault.com/pkg/brew/apib/) - Shares av.db curated category or tags: cli, developer-tools, http. - [atac](https://www.automicvault.com/pkg/brew/atac/) - Shares av.db curated category or tags: cli, developer-tools, http. - [autobench](https://www.automicvault.com/pkg/brew/autobench/) - Shares av.db curated category or tags: cli, developer-tools, http. - [curlconverter](https://www.automicvault.com/pkg/npm/curlconverter/) - Local package facts share a topical domain.
