Use environmental variables in password

[AGSCL]

Is it possible to use 'r Sys.getenv("CANVASPASS")' or "r as.character(read.table('H:/Mi unidad/Curso_UDP/pass_canvas.txt', quote='"', comment.char=''))"' ` in password YAML?

output: fidelius::html_password_protected: style: button_text: "Ingresar clave" password: 'r Sys.getenv("CANVASPASS")' preview: false hint: "" bundle: true output_format: rmarkdown::html_document: toc: true # table of content true toc_depth: 5 # upto three depths of headings (specified by #, ## and ###) toc_float: true

Hi @AGSCL,

I think this should be possible with something like:

---
output:
  fidelius::html_password_protected:
    password: `r Sys.getenv('CANVASPASS')`
    output_format: rmarkdown::html_document
---

Let me know if this does not work for you.

Hi,

I get the following error

Error in yaml::yaml.load(..., eval.expr = TRUE) : 

  Scanner error: while scanning for the next token at line 3, column 15 found character that cannot start any token at line 3, column 15

If I replace it with "`r Sys.getenv('Key1')`", it looks that it don't evaluate the code, so If I put the following password, it work: `r Sys.getenv('Key1')`

I was encountering the same error in yaml::yaml.load(..., eva.expr = TRUE). I found the !expr tag as described in yaml::yaml.load() to work. For example:

output: 
  fidelius::html_password_protected:
    password: !expr as.character(1+1)
