I noticed that I can’t suppress output using a semicolon when creating a document using Weave. For example:

```julia
#' Test Weave's handling of output suppression via ;
c = rand();
#' should show no output.

```

Here’s what the HTML looks like:

How can I suppress output?

You have to set the chunk option `results="hidden"`. This can be done with a line starting with `#+` above your chunk.

```julia
#' Test Weave's handling of output suppression via
#+ results="hidden"
c = rand()
c += 1
#' should show no output.
c

```
