|
|
An extremely limited version of Clojure in Clojure for shell-scripting.
|
||
|
|
|
||
|
|
Properties:
|
||
|
|
|
||
|
|
- pure (no side effects)
|
||
|
|
- interprets only one form
|
||
|
|
- reads from stdin and writes to stdout
|
||
|
|
|
||
|
|
## Status
|
||
|
|
|
||
|
|
Experimental, mostly for fun.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
`bb` supports the following options:
|
||
|
|
|
||
|
|
- `--version`: if present, prints current version of `bb` and exits.
|
||
|
|
|
||
|
|
By default, the first argument to `bb` is the form to be executed. There is one
|
||
|
|
special variable, `*in*`.
|
||
|
|
|
||
|
|
Examples:
|
||
|
|
|
||
|
|
``` shellsession
|
||
|
|
$ echo 1 | bb '(inc *in*)'
|
||
|
|
2
|
||
|
|
|
||
|
|
$ echo '[1 1 1 1 2]' | bb '(vec (dedupe *in*))'
|
||
|
|
[1 2]
|
||
|
|
|
||
|
|
$ echo '[1 1 1 1 2]' | bb '(inc (first *in*))'
|
||
|
|
2
|
||
|
|
|
||
|
|
$ echo '[{:foo 1} {:bar 2}]' | bb '(filter :foo *in*)'
|
||
|
|
({:foo 1})
|
||
|
|
|
||
|
|
$ echo '"babashka"' | bb '(re-find (re-pattern "b.b.*") *in*)'
|
||
|
|
"babashka"
|
||
|
|
```
|
||
|
|
|
||
|
