curl.mp4
curl.nvim allows you to run HTTP requests with curl from a scratchpad, and display the formatted output
- Introduces the ".curl" filetype, where pressing enter will execute a curl request under the cursor
- Quality of life formatting features, so that writing out curl commands is a little less tedious
- Output is formatted using JQ
- Open a curl command buffer that is either persisted globally or per working directory
- Store and retrieve collections (named files) that are either persisted globally or per working directory
- It's just curl, so all the headers and auth flags you already know works
See the features section for more information.
The plugin aims to be 100% compatible with curl; if a curl command can execute in your shell, you will be able to paste it in to the scratch buffer and run it. Because of this, the plugin attempts to get the balance of being ergonomic and convenient, while still using the knowledge of curl you already have.
Installation example for Lazy:
{
"oysandvik94/curl.nvim",
cmd = { "CurlOpen" },
dependencies = {
"nvim-lua/plenary.nvim",
},
config = true,
}
To get started quickly, check out some commands under to get you going. For more detailed documentation, see examples under Features!
" A buffer that is scoped to the current working directory
:CurlOpen
" A global buffer that will be the same for all Neovim instances
:CurlOpen global
" Create or open a new collection with the given scope
:CurlOpen collection global {any_name}
:CurlOpen collection scoped {any_name}
" Open a picker to select a collection
:CurlCollection global
:CurlCollection scoped
These commands will open the curl.nvim tab. In the left buffer, you can paste or write curl commands, and by pressing Enter, the command will execute, and the output will be shown and formatted in the rightmost buffer.
If you wish, you can select the text in the right buffer, and filter it using jq, i.e.
ggVG! jq '{query goes here}'
Below follows some example keymaps, (see the API docs for possibilites)
local curl = require("curl")
curl.setup({})
vim.keymap.set("n", "<leader>cc", function()
curl.open_curl_tab()
end, { desc = "Open a curl tab scoped to the current working directory" })
vim.keymap.set("n", "<leader>co", function()
curl.open_global_tab()
end, { desc = "Open a curl tab with gloabl scope" })
-- These commands will prompt you for a name for your collection
vim.keymap.set("n", "<leader>csc", function()
curl.create_scoped_collection()
end, { desc = "Create or open a collection with a name from user input" })
vim.keymap.set("n", "<leader>cgc", function()
curl.create_global_collection()
end, { desc = "Create or open a global collection with a name from user input" })
vim.keymap.set("n", "<leader>fsc", function()
curl.pick_scoped_collection()
end, { desc = "Choose a scoped collection and open it" })
vim.keymap.set("n", "<leader>fgc", function()
curl.pick_global_collection()
end, { desc = "Choose a global collection and open it" })
To verify the installation run :checkhealth curl
.
You can configure curl.nvim by running the curl.setup()
function, passing a table as the argument.
Or if you use Lazy, just pass the table into opts
as described here.
Default Config
{
-- Table of strings to specify default headers to be included in each request, i.e. "-i"
default_flags = { },
-- Specify an alternative curl binary that will be used to run curl commands
-- String of either full path, or binary in path
curl_binary = nil,
mappings = {
execute_curl = "<CR>"
}
}
Opening any file with the ".curl" file extension will activate this plugins features. You will get some syntax highlighting and the ability to execute curl commands from you buffer. Since any ".curl" file will work, you can manage your own collection instead of using the builtin system, and even check in files to your repository.
JSON bodies do not have to be wrapped in quotes, making it easier to format JSON with JQ (va{:!jq)
See example
curl -X POST https://jsonplaceholder.typicode.com/posts
-H 'Content-Type: application/json'
-d
{
"title": "now try this"
}
You dont need a trailing \, but it wont matter if they are there, making it easier to copy-paste requests
See example
curl -X POST https://jsonplaceholder.typicode.com/posts \
-H 'Content-Type: application/json' \
-d '{"title": "now try this"}'
Headers and/or parts of the body can be commented out using '#', making ad-hoc experimenting with requests easier
See example
curl -X POST https://jsonplaceholder.typicode.com/posts
-H 'Content-Type: application/json'
-d
{
# "title": "remember me"
"title": "now try this"
}
Basic auth and bearer tokens work, and can be retrieved from environment variables
Caution
The command scratch buffer is stored in plaintext in your Neovim data directory, be careful when using literal secrets!
See example
curl -u "username:password" http://httpbin.org/basic-auth/username/password
curl -u "username:$PASSWORD_TEST" http://httpbin.org/basic-auth/username/mypassword
curl -X GET "https://httpbin.org/bearer" -H "accept: application/json" -H "Authorization: Bearer myrandomtoken"
curl -X GET "https://httpbin.org/bearer" -H "accept: application/json" -H "Authorization: Bearer $TOKEN_TEST"
There are multiple ways to work with the scratch buffers, so you can tailor it to your own workflow. By default, running ":CurlOpen" will open a command buffer that is tied to your current working directory. If you treat directories as "projects", and always open neovim in the root of your project directories, then this option might be useful for you.
Using ":CurlOpen global" you can open a global buffer that will always be the same across your Neovim instances.
If you want more control, or would like to organize your curl commands in logical collections, you can use the "collection" functionality to create named command buffers.
These are also scoped either globally or per working directory.
" Create or open a collection
:CurlOpen collection global mycoolcurls
:CurlOpen collection scoped mycoolcurls
" Choose a collection from a picker
:CurlCollection scoped
:CurlCollection global
require("curl").open_global_collection("mycoolcurls")
require("curl").open_scoped_collection("mycoolcurls")
-- This will prompt you for a name instead
require("curl").create_global_collection()
-- Choose a collection from a picker
require("curl").pick_scoped_collection()
The pickers are based on vim.ui.select, which means it will use whatever frontend you have configured. This might be the neovim default picker, or telescope/fzf-lua if configured. See for example dressing.nvim or this telescope extension for ways of configuring this.
In the future, I (or someone else) might create a dedicated telescope/fzf picker to get features like preview enabled.
This section describes all the methods in the exposed lua api
See lua api
local curl = require('curl')
-- These functions will open the curl tab with the given command buffer
-- If the curl tab is open, it will replace the existing command buffer with the selected on, and
-- go to the tab
-- Command buffer scoped to the current working directory
curl.open_curl_tab()
-- Globally scoped command buffer available in all Neovim instances
curl.open_global_tab()
-- Close the tab containing curl buffers
curl.close_curl_tab()
-- Executes the curl command under the cursor when the command buffer is open
-- Also executed by the "execute_curl" mapping, as seen in the configuration. Mapped to <CR> by default
curl.execute_curl()
--------------------
-- The below functions are related to collections
-- Will either open or create a collection with the given name as input
curl.open_scoped_collection({name})
curl.open_global_collection({name})
-- Same as get_global_colletion(), but does not take
-- input and promps the user for a name with vim.ui.input
curl.create_global_collection()
curl.create_scoped_collection()
-- Return a list of collections in a table
-- The name is the given name, not the filename (".curl" extension is omitted)
curl.get_global_collections()
curl.get_scoped_collections()
-- Opens a picker using vim.ui.select() that will open the
-- given collection when selected
curl.pick_global_collection()
curl.pick_scoped_collection()
-- Specify an alternative curl binary that will be used to run curl commands
-- String of either full path, or binary in path
curl.set_curl_binary("someothercurl")
Interesting features that might arrive soon:
- Format JSON under the cursor in the scratch window with a single keybind
- Be able to do simple jq queries in the output window. For example: while the cursor is on a key in the json, execute a keybind to filter the entire json for that key
- Enhance organization, by maybe folds, creating a picker for commands in the scratch, or multiple named scratches
- kulala.nvim using HTTP file syntax instead. This is similar to Jetbrains HTTP client and vscode rest-client.
- rest.nvim using HTTP file syntax instead. This is similar to Jetbrains HTTP client and vscode rest-client.
