Command line tool for URL parsing and manipulation

Video presentation

Examples

Replace the host name of a URL:

$ trurl --url https://curl.se --set host=example.com
https://example.com/

Create a URL by setting components:

$ trurl --set host=example.com --set scheme=ftp
ftp://example.com/

Redirect a URL:

$ trurl --url https://curl.se/we/are.html --redirect here.html
https://curl.se/we/here.html

Change port number:

$ trurl --url https://curl.se/we/../are.html --set port=8080
https://curl.se:8080/are.html

Extract the path from a URL:

$ trurl --url https://curl.se/we/are.html --get '{path}'
/we/are.html

Extract the port from a URL:

$ trurl --url https://curl.se/we/are.html --get '{port}'
443

Append a path segment to a URL:

$ trurl --url https://curl.se/hello --append path=you
https://curl.se/hello/you

Append a query segment to a URL:

$ trurl --url "https://curl.se?name=hello" --append query=search=string
https://curl.se/?name=hello&search=string

Read URLs from stdin:

$ cat urllist.txt | trurl --url-file -
...

Output JSON:

$ trurl "https://fake.host/hello#frag" --set user=::moo:: --json
[
  {
    "url": "https://%3a%3amoo%3a%3a@fake.host/hello#frag",
    "scheme": "https",
    "user": "::moo::",
    "host": "fake.host",
    "port": "443",
    "path": "/hello",
    "fragment": "frag"
  }
]

Remove tracking tuples from query:

$ trurl "https://curl.se?search=hey&utm_source=tracker" --trim query="utm_*"
https://curl.se/?search=hey

Show a specific query key value:

$ trurl "https://example.com?a=home&here=now&thisthen" -g '{query:a}'
home

Sort the key/value pairs in the query component:

$ trurl "https://example.com?b=a&c=b&a=c" --sort-query
https://example.com?a=c&b=a&c=b

Work with a query that uses a semicolon separator:

$ trurl "https://curl.se?search=fool;page=5" --trim query="search" --query-separator ";"
https://curl.se?page=5

Accept spaces in the URL path:

$ trurl "https://curl.se/this has space/index.html" --accept-space
https://curl.se/this%20has%20space/index.html

Install

Linux

It's quite easy to compile the C source with GCC:

$ make
cc  -W -Wall -pedantic -g   -c -o trurl.o trurl.c
cc   trurl.o  -lcurl -o trurl

trurl is also available in some Linux distributions. You can try searching for it using the package manager of your preferred distribution.

Windows

Download and run Cygwin installer.
Follow the instructions provided by the installer. When prompted to select packages, make sure to choose the following: curl, libcurl-devel, libcurl4, make and gcc-core.
(optional) Add the Cygwin bin directory to your system PATH variable.
Use make, just like on Linux.

Prerequisites

Development files of libcurl (e.g. libcurl4-openssl-dev or libcurl4-gnutls-dev) are needed for compilation. Requires libcurl version 7.62.0 or newer (the first libcurl to ship the URL parsing API).

trurl also uses CURLUPART_ZONEID added in libcurl 7.81.0 and curl_url_strerror() added in libcurl 7.80.0

It would certainly be possible to make trurl work with older libcurl versions if someone wanted to.

Older libcurls

trurl builds with libcurl older than 7.81.0 but will then not work as good. For all the documented goodness, use a more modern libcurl.
