A reference card / cheat sheet for choosing the right kind of function parameter to receive and return objects in C++ functions. Download reference card.

C++ gives fine-grained control over argument passing and returning that many options exits. There’s been enough over-thinking and discussions in the community. Thankfully experts have noticed this and have arrived at sane defaults. Since the options are more and involved, having a ready reckoner is useful when coding.

The reference card is written in the venerated Org mode.

Dependencies

• Emacs with Org mode
• CheatSheet by Musa Al-hassy
• pdfTeX with some additional packages
• Pygments for syntax highlighting ($PATH should have pygmentize; optional)

On Arch Linux, I’d to install these packages

• texlive-bin (for pdflatex)
• texlive-latexextra (for wrapfig.sty)
• texlive-fontsextra (for bbold.sty)
• texlive-science (for mathematic symbols stmaryrd.sty; optional)
• community/pygmentize

As a single command

yay -S --needed extra/texlive-latexextra extra/texlive-fontsextra extra/texlive-science community/pygmentize

Other Linux repositories should have equivalent packages to get these.

Emacs Packages

• org-plus-contrib (from https://orgmode.org/elpa/)
• org-ref (optional, for citations, bibliography, …)

Append this to your Emacs configuration

;; for the the CheatSheetSetup.org section headings to be ignored
(require 'ox-extra)
(ox-extras-activate '(ignore-headlines))

;; for syntax highlighting source blocks
(setq org-latex-listings 'minted
      org-latex-packages-alist '(("" "minted"))
      org-latex-pdf-process
      '("pdflatex -shell-escape -output-directory %o %f"
        "biber %b"
        "pdflatex -shell-escape -output-directory %o %f"
        "pdflatex -shell-escape -output-directory %o %f"))
