# Code in Bower

> Attach R and Python scripts, read them without downloading, search inside them, and get properly formatted code back from Bird.

Bower handles the code that sits alongside your experiments: scripts you upload,
code Bird writes back to you, and code blocks inside your notes.

This page covers what works, and one thing that does not.

## Attach a script

Upload source files the way you upload anything else: drag them into a
collection, use the upload button, or attach one to a Bird chat.

The formats Bower accepts include `.R`, `.Rmd`, `.Rnw`, `.py`, `.ipynb`, `.sql`,
`.sh`, `.jl` for Julia, `.m` for MATLAB, `.do` and `.ado` for Stata, plus
`.json`, `.yaml`, `.xml`, `.c`, `.cpp`, `.java`, `.js` and `.ts`.

If you tried this before and Bower turned you away, that was not you doing it
wrong. Most operating systems have no registered file type for a `.R` or a
`.do`, so your browser hands the upload over with the type field blank, and
Bower used to refuse anything it could not identify. It now recognises these
files by their extension.

## Read it without downloading it

Open the attachment and you see the file itself, syntax highlighted, with the
language named at the top and buttons to copy or download it.

An `.Rmd` keeps its chunk headers intact, options included, so `include=FALSE`
is still visible where you wrote it.

A few accepted formats have no highlighter yet, `.css` and `.xml` among them.
Those still open and read as code, just without the colours. Files over 256 KB
are not rendered in the browser: you get the file details and a download button
instead, because syntax highlighting a file that size would lock up the tab.

## Search inside your scripts

When a script is brought in through **import**, Bower reads the text inside it.
Search for a function name you defined and the file comes back, and Bird can
read the file when you ask about it, rather than asking you to paste the code
into the chat.

<Note>
  This applies to files brought in through import, or attached in a Bird chat. A
  file attached directly to an existing note is stored and previewed, but its
  contents are not indexed, so it will not turn up in search.

## Code in your notes

Code blocks in the editor are syntax highlighted, and each one has a language
picker in its top corner. Pick R, Python, SQL or any other supported language
and the block colours accordingly.

Bower will not guess the language for you. A block with no language set renders
as plain text, because a wrong guess quietly recolours your code and gives you
no sign it happened. Short R snippets are the easiest thing in the world to
mistake for something else.

The language you pick travels with the note, so a block you tag as R is stored,
searched and read back as R.

## Code from Bird

Ask Bird for a script and you get it back properly fenced and highlighted, with
copy and download on the block.

Bird writes in the language of your work. If your files and notes are R, you get
R back, rather than a Python translation of what you asked for.

## What Bird can and cannot run

Bird can run **Python**, in a sandbox, for analysis over your data.

Bird cannot run R. There is no R interpreter anywhere in Bower.

Ask it to run an R script and it will say so, then offer the two things that
actually exist: write the script out so you can run it yourself in RStudio, or
do the equivalent analysis in Python and label it clearly as Python. It will not
run something else and hand you the number as though it came from your code.

This is deliberate. A result that came from a quiet translation of your analysis
is worse than no result, because you have no way to tell it apart from the real
thing.
