# ctags-lang-rmarkdown(7)

Random notes about tagging R Markdown source code with Universal Ctags

## Name

ctags-lang-rmarkdown - Random notes about tagging R Markdown source code with Universal Ctags

## SYNOPSIS

```
ctags ...--extras=+{subparser}{guest} --languages=+RMarkdown ...
ctags ...--extras=+{subparser}{guest} --language-force=RMarkdown ...
ctags ...--extras=+{subparser}{guest} --map-RMarkdown=+.rmd ...
```

## DESCRIPTION

RMarkdown parser is an exclusive subparser stacked on top of the Markdown parser. It works when:

- •

  the Markdown parser is enabled,

- •

  the **subparser** extra is enabled, and

- •

  the RMarkdown parser itself is enabled.

The RMarkdown parser extends the way of detecting **codeblocks** from the Markdown parser. This extension is for running guest parsers on **code chunks**.

The Markdown parser expects the following syntax represents codeblocks:

````
```language-name
        ...
```
````

For an example

````
```r
        ...
```
````

The RMarkdown parser accepts the following syntax for code chunks:

````
```{language-name chunk-label, ...}
        ...
```
````

For an example

````
```{r precalc fig.height=4}
        ...
```
````

Give *--extras=+{guest}* for enabling **guest** to command line if you want to run proper parsers on lines inside code chunks.

The parser extracts chunk labels coming after *language-name* as *chunklabel* kind objects. In the example, the RMarkdown parser extracts *precalc* as a *chunklabel* kind object. The *chunklabel* kind is enabled by default.

## EXAMPLES

"input.rmd"

````
# Section 1
```{r myblock}
        zero_fun <- function () {
                return 0
        }
```
# Section 2
````

"output.tags" with "--options=NONE --extras=+{guest} --fields=+KZln -o - input.rmd"

````
Section 1       input.rmd       /^# Section 1$/;"       chapter line:1  language:Markdown
Section 2       input.rmd       /^# Section 2$/;"       chapter line:9  language:Markdown
myblock input.rmd       /^```{r myblock}$/;"    chunklabel      line:3  language:RMarkdown
zero_fun        input.rmd       /^      zero_fun <- function () {$/;"   function        line:4  language:R
````
