# CL-INFO - Common Lisp Environment Reporter

[![](https://github-actions.40ants.com/40ants/cl-info/matrix.svg?only=ci.run-tests)][3904]

This is a small utility, useful to display information about you Common
Lisp environment. You might want to call it in the `CI` pipeline or
to use it when rendering a crash report in some client applications.

## Usage from Common Lisp

It's main entry point is [`cl-info:get-cl-info`][5b06] function. It returns an object with
customized `PRINT-OBJECT` method. You can use it to output debug
information in your programs.

[`cl-info`][3d51] collects inforrmation about `OS`, Lisp Implementation, `ASDF`, installed
Quicklisp distributions:

Also, you can gather information about separate systems using [`cl-info:get-system-info`][9306]
function:

```text

System: HAMCREST 0.4.2
       /Users/art/common-lisp/cl-hamcrest/src/
```

## Usage From Command-line

Also, you can use [`cl-info`][3d51] as a command-line utility. It is useful to
output information about common lisp environment running on `CI` server.

Here is how to do it:

```shell
# Here we use a Roswell, to install utility
[art@art-osx:~]% ros install 40ants/cl-info
   
# And now request information about lisp and some systems
[art@art-osx:~]% cl-info weblocks clack jonathan some-other-system
