Compact help

[ThiefMaster]

It would be nice if httpie had a compact help.

I tend to forget the various request item delimiters, but http --help spams the terminal scrollback with lots of unrelated information (I know, I can use less, but meh, I'm lazy). Why not include this in the compact "usage" printed when just running http?

[rozuur]

wouldn't it be better to have a tldr page for http instead of usage?

[ThiefMaster]

You can't install this kind of documentation using pip like you can with httpie... just like you can't install a manpage with pip

[rozuur]

I am not referring to installing a tldr page with pip, just providing another alternative for your problem. Will also help others who are using tldr pages.

[jkbrzt]

@rozuur there's now a tl;dr page: http://www.ostera.io/tldr.jsx/#/http

Better help system is planned.

What about writing a man page with the current content of http --help, and making http --help just print

usage: http [--json] [--form] [--pretty {all,colors,format,none}]
            [--style STYLE] [--print WHAT] [--verbose] [--headers] [--body]
...

?

[ducaale]

Most rust-based CLI tools, including ripgrep, show a compact or a detailed help page depending on whether -h or --help flag has been used.

Httpie currently uses -h as a short form for --headers, but is there a chance to change that before the 3.0 release as a breaking change?

[ThiefMaster]

changing switches in a cli is a terrible idea, even in a major release. you just don't do something like that.

[ThiefMaster]

maybe it could do things like git and display a man page instead of dumping so much to stdout directly?

[ducaale]

changing switches in a cli is a terrible idea, even in a major release. you just don't do something like that.

To maintain backward compatibility, what if -h stood for --headers only when the URL is available? Of course, the docs wouldn't mention this behavior to steer away users from using -h as --headers.

$ http -h
usage: http [--json] [--form] [--pretty {all,colors,format,none}]
            [--style STYLE] [--print WHAT] [--verbose] [--headers] [--body]
...

$ http httpbin.org/json -h

The current output of http -h is

            [--unsorted] [--sorted] [--response-charset ENCODING] [--response-mime MIME_TYPE] [--format-options FORMAT_OPTIONS] [--print WHAT]

If you remove the last line and change the exit code to 0, you would end up with a behaviour similar to ripgrep

What if the --help flag displayed a compact help while a help subcommand is was used for more complete documentation?

$ http --help
HTTPie v0.3.0

HTTPie: modern, user-friendly command-line HTTP client for the API era. <https://httpie.io>

USAGE:
    http [OPTIONS] [METHOD] URL [REQUEST_ITEM ...]

OPTIONS:
    -j, --json       (default) Serialize data items from the command line as a JSON object
    -f, --form       Serialize data items from the command line as form fields
    -m, --multipart  Like --form, but force a multipart/form-data request even without files

Run `http help` or visit https://httpie.io/docs/cli for more complete documentation.

$ http help
HTTPie v0.3.0

HTTPie: modern, user-friendly command-line HTTP client for the API era. <https://httpie.io>

USAGE:
    http [OPTIONS] [METHOD] URL [REQUEST_ITEM ...]

OPTIONS:
  --json, -j
      (default) Data items from the command line are serialized as a JSON object.
      The Content-Type and Accept headers are set to application/json
      (if not specified).

  --form, -f
      Data items from the command line are serialized as form fields.

      The Content-Type is set to application/x-www-form-urlencoded (if not
      specified). The presence of any file fields results in a
      multipart/form-data request.

  --multipart
      Similar to --form, but always sends a multipart/form-data
      request (i.e., even without files).
