# Convert the syntax of theorem and proof environments from code blocks to fenced Divs

Source:`R/utils.R`

`fence_theorems.Rd`

This function converts the syntax ````{theorem, label, ...}` to
`::: {.theorem #label ...}` (Pandoc's fenced Div) for theorem
environments.

## Usage

`fence_theorems(input, text = xfun::read_utf8(input), output = NULL)`

## Arguments

- input
Path to an Rmd file that contains theorem environments written in the syntax of code blocks.

- text
A character vector of the Rmd source. When

`text`

is provided, the`input`

argument will be ignored.- output
The output file to write the converted input content. You can specify

`output`

to be identical to`input`

, which means the input file will be overwritten. If you want to overwrite the input file, you are strongly recommended to put the file under version control or make a backup copy in advance.

## Value

If `output = NULL`

, the converted text is returned, otherwise
the text is written to the output file.
