Editor support


The recommended editor to use with Pweave is Atom. language-weave package has Pweave syntax highlighting for several markups and support running code from chunks interactively using Hydrogen.

You can use Hydrogen keybindings to run code e.g ctrl-enter to run a line and ctrl-alt-enter to run entire chunk.

Install from Atom or using apm:

apm install language-weave Hydrogen

To install packages that I find useful for preview and formatting run:

apm install language-markdown atom-html-preview pdf-view

And for terminal support connected to Hydrogen kernel:

apm install hydrogen-launcher platformio-ide-terminal

Pweave syntax highlighting in Atom and output from Hydrogen.


Another good option is to use a Spyder plugin called Spyder reports that can render Pweave documents inside Spyder.

Pweave can also publish scipts using Spyder cell format with #%% code cell mark up .


You can use Emacs with noweb-mode. I use .prstw for Pweave documents written with reST markup and .ptexw for LaTeX markup. Here is what I have in my ~/.emacs.d/init.el to make Emacs recognize my Pweave documents correctly.

;Pnw-mode for Pweave reST documents
(defun Pnw-mode ()
       (require 'noweb-font-lock-mode)
       (setq noweb-default-code-mode 'python-mode)
       (setq noweb-doc-mode 'rst-mode))

(setq auto-mode-alist (append (list (cons "\\.prstw$" 'rstw-mode))

;Plw-mode for Pweave Latex documents
(defun Plw-mode ()
       (require 'noweb-font-lock-mode)
       (setq noweb-default-code-mode 'python-mode)
       (setq noweb-doc-mode 'latex-mode))

(setq auto-mode-alist (append (list (cons "\\.ptexw$" 'texw-mode))

The code simply sets the documentation mode (noweb-doc-mode as rst-mode) as reStructuredText or LaTeX depending on the extension and the code mode as Python, so that the code chunks will be correctly formatted.
