Command Line Tool to Work with Transit Format

Command Line Tool to Work with Transit Format

• Free software: ISC license
• Documentation: https://transito.readthedocs.org.

Features

• convert to and form json, edn, transit
• read content from stdin or files

Usage

$ transito -h
usage: transito [-h] {t2j,j2t,e2t,t2e,http} ...

Transit CLI

positional arguments:
  {t2j,j2t,e2t,t2e,http}
    t2j                 convert transit to json
    j2t                 convert json to transit
    e2t                 convert edn to transit
    t2e                 convert transit to edn
    http                make http requests with transit data

optional arguments:
  -h, --help            show this help message and exit

Conversions

Convert Transit to JSON from a file:

$ transito t2j examples/ex1.transit

[":keyword", "~lala", 1, 1.2, true, null, [], ["hi", "a"]]

Convert Transit to JSON from stdin:

$ transito t2j -

["~#list",["~:keyword","~$lala",1,1.2,true,null,[],["hi",["~#char","a"]]]]
[":keyword", "~lala", 1, 1.2, true, null, [], ["hi", "a"]]

Note

The first line is the input, then I pressed Enter and Ctrl+D

Piping from another command:

$ echo '["~#list",["~:keyword","~$lala",1,1.2,true,null,[],["hi",["~#char","a"]]]]' | transito t2j -

[":keyword", "~lala", 1, 1.2, true, null, [], ["hi", "a"]]

Same for Edn:

$ transito t2e examples/ex1.transit

(keyword lala 1 1.2 true nil [] ["hi" \a])

$ echo '["~#list",["~:keyword","~$lala",1,1.2,true,null,[],["hi",["~#char","a"]]]]' | transito t2e -

(keyword lala 1 1.2 true nil [] ["hi" \a])

$ transito t2e -

["~#list",["~:keyword","~$lala",1,1.2,true,null,[],["hi",["~#char","a"]]]]
(keyword lala 1 1.2 true nil [] ["hi" \a])

you should get the idea, some with transit as output just in case:

$ transito e2t -
(keyword lala 1 1.2 true nil [] ["hi" \a])
["~#list",["~$keyword","~$lala",1,1.2,true,null,[],["hi",["~#char","a"]]]]

$ transito t2j -
["~#list",["~$keyword","~$lala",1,1.2,true,null,[],["hi",["~#char","a"]]]]
["~keyword", "~lala", 1, 1.2, true, null, [], ["hi", "a"]]

Note

to json conversions are lossy, this means that in order to not crash when serializing keywords, symbols and chars we do a lossy serialization, chars are strings, keywords are strings starting with : and symbols are strings starting with ~.

The idea of this translation is to provide a way to view the edn or transit as json and shouldn’t be used to send this data to a production system.

HTTP Requests

You an make an http request that supports transit, json or edn but writting and reading the request and response in a more readable way, for example, make a request writing edn that will be transformed to transit before being sent, the response will be transformed to edn if possible to make it more readable:

$ echo '(increment {:value 20})' | transito http post http://localhost:8080/action e2t -

Status: 200
Content-Type: application/transit+json
Content-Length: 28

{:value [:count]}

You may ask, isn’t it complected? yes, yes it is.
