a curl wrapper with placeholder, bookmark and environment powers just like postman but for the terminal

Features

• ☑️.env files
• ☑️.yaml env files
• ☑️placeholder evaluation, with the minijinja template engine
  • in urls
  • in http headers (-H | --header arguments)
  • in every other passed curl parameter
• ☑️save request as a bookmark, containing
  • curl arguments
  • http headers
  • http method
  • placeholders
• ☑️pass all arguments after -- to curl, that makes drop-in-replacement possible
• ☑️execute a bookmarked request
• ☑️special placeholder variables that would interact with the user
  • ☑️prompt for a password as {{ prompt_password() }} curlz r https://api.github.com/user -- -u "{{ username }}:{{ prompt_password() }}"
  • ☑️prompt for interactive input with a label as {{ prompt_for("Username") }} or {{ prompt_for("Birthdate") }} curlz -- -u "{{ prompt_for("Username") }}:{{ prompt_password() }}" https://api.github.com/user
• ☑️evaluate placeholders at the beginning of an url like: sh curlz r --define 'host=https://httpbin.org' '{{host}}/get?show_env={{ prompt_for("show_env") }}'
• ☑️special placeholder for developers, like for Json Web Tokens (JWT)
  • example: {{ jwt(claims, signing_key) }}, where claims and signing_key are looked up at the environment file or can be directly provided map and string sh curlz r -H 'Authorization: Bearer {{ jwt({"uid": "1234"}, "000") }}' https://httpbin.org/bearer -- -vvv

TODOs

• [ ] support rest client template language see #5

Example #1

In this example we're going to download a pre-configured .gitignore for a given language from GitHub via curl

• curl https://api.github.com/gitignore/templates/Rust
• the same with curlz: curlz r https://api.github.com/gitignore/templates/Rust
• Add a placeholder that is interactively requested curlz r 'https://api.github.com/gitignore/templates/{{ prompt_for("Language") | title }}'
• Now let's bookmark this request: sh curlz r --bookmark 'https://api.github.com/gitignore/templates/{{ prompt_for("Language") | title }}' Language: rust Please enter a bookmark name: gitignore
• Finally, we can keep using the bookmark from now on: curlz r gitignore

Template functions

Json Web Token - jwt(claims: map, [signing_key: string])

• arguments:
  • claims: to be a map of key value pairs like {"uid": "1234"} that are the payload of the JWT
  • signing_key: to be a string, this is optional and can be provided at the environment file with a variable named jwt_signing_key
• output: string is a Json Web Token (JWT)
• notes:
  • the hash algorithm is HS256 and the JWT header is {"alg": "HS256", "typ": "JWT"}
  • the claim exp expiry time is set to in 15min by default, but can be overwritten
  • the claim iat issued at timestamp is set automatically and cannot be overwritten
