In-App Editing & File Viewing

Editing

Open collection file in vim

Slumber supports editing your collection file without leaving the app. To do so, open the actions menu (x by default), then select Edit Collection. Slumber will open an external editor to modify the file. To determine which editor to use, Slumber checks these places in the following order:

  • editor field of the configuration file
  • VISUAL environment variable
  • EDITOR environment variable
  • Default to vim

The VISUAL and EDITOR environment variables are a common standard to define a user's preferred text editor. For example, it's what git uses by default to determine how to edit commit messages. If you want to use the same editor for all programs, you should set these. If you want to use a command specific to Slumber, set the editor config field.

Slumber supports passing additional arguments to the editor. For example, if you want to open VSCode and have wait for the file to be saved, you can configure your editor like so:

editor: code --wait

The command will be parsed like a shell command (although a shell is never actually invoked). For exact details on parsing behavior, see shell-words.

Paging

You can open request and response bodies in a separate file browser if you want additional features beyond what Slumber provides. To configure the command to use, set the PAGER environment variable or the pager configuration field:

pager: bat

Slumber will check these places in the following order for a command:

  • pager field of the configuration file
  • PAGER environment variable
  • Default to less (Unix) or more (Windows)

The pager command uses the same format as the editor field. The command is parsed with shell-words, then a temporary file path is passed as the final argument.

To open a body in the pager, use the actions menu keybinding (x by default, see input bindings), and select View Body.

Setting a content-specific pager

If you want to use a different pager for certain content types, such as using jless for JSON, you can pass a map of MIME type patterns to commands. For example:

pager:
  json: jless
  default: less

For more details on matching, see MIME Maps.
