# 🎀 Changelog
## Unreleased
### Added
- `fs.pipe` function to get a pair of connected files (a pipe).
- Added an alternative 2nd parameter to `hilbish.run`, which is `streams`.
`streams` is a table of input and output streams to run the command with.
It uses these 3 keys:
- `input` as standard input for the command
- `out` as standard output
- `err` as standard error
Here is a minimal example of the new usage which allows users to now pipe commands
directly via Lua functions:
```lua
local fs = require 'fs'
local pr, pw = fs.pipe()
hilbish.run('ls -l', {
stdout = pw,
stderr = pw,
})
pw:close()
hilbish.run('wc -l', {
stdin = pr
})
```
## [2.2.3] - 2024-04-27
### Fixed
- Highligher and hinter work now, since it was regressed from the previous minor release.

Runs `cmd` in Hilbish's shell script interpreter.
Specifies the output and input streams the command should use.
For example, to write command output to a sink.
As a table, the caller can directly specify the standard output, error, and input
streams of the command with the table keys `out`, `err`, and `input` respectively.
As a boolean, it specifies whether the command should use standard output or return its output streams.
#### Parameters
`string` **`cmd`**
`table|boolean` **`streams`**
`boolean` **`returnOut`**
If this is true, the function will return the standard output and error of the command instead of printing it.
