Make requests, select JSON responses, nest them in other requests: A magnificent syntax for blazingly fast cli HTTP calls, made for humans.

Getting started
Install & Update
At the moment, you can install or update glue for your system by building it from source. It has been done quite easy by the script install.sh.
All build dependencies (including Rust) will be deleted right after the installation automatically if Rust wasn't already on your system.
- Clone the repo
git clone https://github.com/mikesposito/glue- Go to glue root directory
cd glue- Add execute permission and run install.sh
chmod +x ./install.sh && ./install.shUsage
To start an interactive glue shell, simply run:
gluealternatively, you can also execute a request directly:
glue <REQUEST>The simplest request you can do with glue is using just the method and the url:
glue 'get https://dog.ceo/api/breeds/list/all'
# or in glue shell:
get https://dog.ceo/api/breeds/list/allSyntax
Overview
The main gluescipt request syntax is the following:
[METHOD] [URL] [OPERATORS]Methods available
| Glue Keyword | Description |
|---|---|
get |
Executes a GET http call |
post |
Executes a POST http call |
patch |
Executes a PATCH http call |
put |
Executes a PUT http call |
delete |
Executes a DELETE http call |
req |
Reuses a saved request response from memory |
Operators available
Operators allow to execute operations on requests (body, headers params, nesting), on responses (selectors, variables)
| Operation | Syntax | Example |
|---|---|---|
| JSON Result Selector |
^selector
|
^$.message |
| Body attribute |
~key=value
|
~username=admin |
| Body attribute quoted |
~key="value"
|
~fullname="John Doe" |
| Raw JSON body |
~#-json-#
|
~#-{"username": "admin"}-# |
| Header attribute |
*key=value
|
*authorization=xxx |
| Header attribute quoted |
*key="value"
|
*authorization="Bearer xxx" |
| Nested request |
{ nested_request }
|
get api.com/users/{get api.com/me} |
| Save response in var |
>var
|
>login_request |
| Sequential request separator |
request; other_request
|
req test1; req test2 |
JSON result selector
If the response is of type JSON, you can add a jsonpath selector to the request with the char ^. Glue will only return the desired value from the response. This applies also for Nested requests.
get https://dog.ceo/api/breeds/list/all^$.message.terrier
# OUTPUT:
# > [GET] https://dog.ceo/api/breeds/list/all

# "westhighland",
# "wheaten",
# "yorkshire"
# ]
# ]Body attributes
You can use the char ~ to add body attributes to the request:
post https://example.com/user/add ~username=admin
# or
post https://example.com/user/add~username=admin
# glue will send a body of type JSON
# with a key "username" with value "admin"Raw JSON Body
Raw JSON values can also be used between ~#-JSON- instead of single attributes:
post https://example.com/users ~#-{ "name": "John" }-#
# or
post https://example.com/users~#-{ "name": "John" }-#Note
Body attributes can take their value from another request's response by using nested requests feature.
Headers
You can use the char * to set headers to the request:
post https://example.com/user/add*authorization=6a75d4d7-84c3
# or
post https://example.com/user/add *authorization=6a75d4d7-84c3
# glue will set Authorization header
# to value "6a75d4d7-84c3"Quotes can also be use to escape special glue chars or spaces in attributes:
post https://example.com/user/add*authorization="Bearer 6a75d4d7-84c3"Note
Headers can take their value from another request's response by using nested requests feature.
Nested requests
One of the most useful features of glue is the request nesting.
You can reuse response values (total or partial) from a request to build another request.
Glue supports infinite nesting and will build a dependency tree, divide it in layers and execute each layer on parallel for the maximum time optimization.
You can use request nesting delimiting the desired nested request with {}:
get api.com/users/{ get api.com/me^$.user.id }/
# glue will execute this two requests:
#Â 1. api.com/me - and will select user.id from the response (eg. 12345)
# 2. api.com/users/12345/Request can also be nested inside body or headers parameters:
get api.com/me *authorization={get api.com/login^$.access_token}/Run file
You can also create a file with request to run, and pass the file path to glue with flag -f to execute it. You can try with one of the sample requests in examples folder:
glue -f examples/sample-request.glueMultiple requests
Files can also contain multiple sequential requests separated by ;.
Take a look at ./examples/sequential-requests.glue.
Save response in variable
You can save a request response in a temporary variable with a name of your choice with the char >, to reuse it without executing the call again.
get https://dog.ceo/api/breeds/list/all >test_reqto use the saved response:
req test_reqYou can also use a selector on the saved response with ^:
req test_req^$.message.terrierNote: Variables are available only in the same glueshell session and dropped at the end of it.
