NEWS

• As of version 1.0.0, there are six addins:

The ‘shiny’ addins are the ones you can see on the above GIFs. The other ones are not interactive. The ‘Prettify C/C++/Java’ addin requires clang-format (it is possible to reindent C/C++/Java (and more) with the ‘Indent (shiny)’ addin).

• As of version 2.0.0, there are five new addins:
  • ‘Indent (PhantomJS)’: allows to reindent code for some languages which were supported by the ‘Indent (shiny)’ addin only, whereas this addin does not run a Shiny app; these languages are C, C++, Java, Fortran, Julia, Python, SAS, Scala, Shell, and SQL. This addin requires phantomjs (the package provides a function to install this software).
  • ‘Prettify LaTeX’: to prettify LaTeX code; works for Sweave code. It requires latexindent, which is included in MikTeX and TeX Live distributions.
  • ‘Prettify Julia’: to prettify Julia code. It requires Julia.
  • ‘Prettify Python’: to prettify Python code. It requires black.
  • ‘Prettify (formatCodeApi)’: to prettify Java, JSON, and Ruby.

Moreover, this version exports the functions used to prettify/reindent. For example:

code <- c(
  "function f(x){",
  "return x+1",
  "}"
)
cat(prettify_V8(code, "javascript"))

gives

function f(x) {
  return x + 1;
}
