Detailed documentation is kept in the GitHub Wiki.
It is abbreviated vscode-org-mode. Commands are prefixed with org. Command titles are prefixed with Org: and followed by capitalized words separated by spaces, eg Org: Insert Heading Respect Content. When referring to the original Org mode, we capitalize the "O" and leave the "m" lower case. This is in keeping with the original team's usage on orgmode. The original Org mode was written for Emacs by Carsten Dominik, with the help and support of an impressive list of geniuses.
Our work is inspired by nurown effectiveness not associated with their original masterpiece. In addition, many aspects of the extension were inspired by the Spacemacs Org layer.

Use C-c ' to edit the current code block. It opens a new major mode edit buffer containing the body of the source code block, ready for any edits.
Use C-c ' again to close the buffer and return to the Org buffer. Header arguments can be set in several ways; Org prioritizes them in case of overlaps or conflicts by giving local settings a higher priority.
Header arguments set through properties drawers apply at the sub-tree level on down. Use C-c C-c to evaluate the current code block and insert its results in the Org document. For a complete list of supported languages see the manual. The following shows a code block and its results. NAME is the name of the variable bound in the code block body.
ASSIGN is a literal value, such as a string, a number, a reference to a table, a list, a literal example, another code block—with or without arguments—or the results of evaluating a code block. How Org handles results of a code block execution depends on many header arguments working together. It controls the collectiontypeformatand handling of code block results. How the results should be collected from the code block. What result types to expect from the execution of the code block.
Org tries to guess it if you do not provide it. How Org processes results. How to insert the results once properly formatted. Code blocks which output results to files—e. It is possible to export the code of code blocks, the results of code block evaluation, both the code and the results of code block evaluation, or none.
Org defaults to exporting code for most languages.
Use C-c C-v t to create pure source code files by extracting code from source blocks in the current buffer.It is possible to export the code of code blocks, the results of code block evaluation, both the code and the results of code block evaluation, or none.
Org defaults to exporting code for most languages. For some languages, such as ditaa, Org defaults to results. To export just the body of code blocks, see Literal Examples.
To selectively export sub-trees of an Org document, see Exporting. The default. The body of code is included into the exported file. The results of evaluation of the code is included in the exported file.
Both the code and results of evaluation are included in the exported file. Neither the code nor the results of evaluation is included in the exported file. Whether the code is evaluated at all depends on other options. To stop Org from evaluating code blocks for greater security, set the org-export-use-babel variable to nilbut understand that header arguments will have no effect. Turning off evaluation comes in handy when batch processing.
For example, markup languages for wikis, which have a high risk of untrusted code.
Stopping code block evaluation also stops evaluation of all header arguments of the code block. This may not be desirable in some circumstances. Org never evaluates code blocks in commented sub-trees when exporting see Comment Lines. On the other hand, Org does evaluate code blocks in sub-trees excluded from export see Export Settings.Org offers two ways to structure source code in Org documents: in a source code block, and directly inline. Both specifications are shown below.
Do not be put-off by having to remember the source block syntax. Org mode offers a command for wrapping existing text in a block see Structure Templates. Org also works with other completion systems in Emacs, some of which predate Org and have custom domain-specific languages for defining templates. Regular use of templates reduces errors, increases accuracy, and maintains consistency. Names the source block so it can be called, like a function, from other source blocks or inline code to evaluate or to capture the results.
Code from other blocks, other files, and from table formulas see The Spreadsheet can use the name to reference a source block. This naming serves the same purpose as naming Org tables. Org mode requires unique names. They mark the start and end of a block that Org requires. It is the identifier of the source code language in the block. See Languagesfor identifiers of supported languages.
Switches provide finer control of the code execution, export, and format see the discussion of switches in Literal Examples. Heading arguments control many aspects of evaluation, export and tangling of code blocks see Using Header Arguments.R is a free software environment for statistical computing and graphics.
R Source Code Blocks in Org Mode
R source code blocks are fully supported in Org Mode with a wide variety of R-specific header arguments. R source code blocks in Org Mode can be used to create R packages, carry out statistical analyses, create graphic displays, and produce reproducible research papers. R source code blocks in Org Mode require a working R installation. This is usually the easiest way to install it; if you need to, instructions for installing from source are found at the ESS website.
To install from Melpa, you need to add it to your package-archives. You also need to ensure that org-babel-load-languages includes an entry for R. Typically, org-babel-load-languages will contain many entries. The example below omits other languages. Additional steps may be necessary on Windows. See this Org-mode mailing list thread for background information. If when trying to execute R source code from Org-mode one encouters the message The system cannot find the path specifiedit may be necessary to set the variable org-babel-R-command in.
Note the addition of --slave --no-save to the custom path, which are the R defaults for Babel. For 64bit Windows users, the R installation process may have installed both 32bit and 64bit binaries. The above path points to the 32bit paths; for 64bit operating systems the analog is:. If a :file filename. What that output is depends on the value of the :results header argument.
If the value is :results file graphics then "base" graphics output is captured to the file specified by the :file argument. A link to the file is inserted into the Org Mode buffer.
An attempt is made to find an R graphics device corresponding to the file extension. Currently, the following extensions are recognized:. If the extension of the file name passed to :file is not recognized, PNG format output is created by default.
If the source code block uses grid-based R graphics, e. This is because the graphics functions from lattice and ggplot2 return objects that must be explicitly printed to see them, using the print function. This happens automatically when run interactively, e.
Some years ago, Erik Iverson summarized the different ways of getting this working. His summary, updated to reflect a change in Org Babel syntax, follows:. See the R help page for the graphics devices e. Arguments to the R graphics device can also be passed as a string in R argument syntax, using the header arg :R-dev-args.

Programming languages live in blocks inside natural language Org-mode documents. A piece of data may pass from a table to a Python code block, then maybe move on to an R code block, and finally end up embedded as a value in the middle of a paragraph or possibly pass through a gnuplot code block and end up as a plot embedded in the document.
Through extending Org-mode with several features for editing exporting and executing source code Babel turns Org-mode into a tool for both Literate Programming and Reproducible Research.
Babel augments Org-mode support for code blocks by providing:. Babel provides new features on a few different fronts, and different people may want to start in different places. All of these use cases, as well as exhaustive documentation of the features of Babel are covered in the Working with Source Code section of the Org manual.
Babel is all about code blocks in Org-mode. If you are unfamiliar with the notion of a code block in Org-mode, where they are called 'src' blocks, please have a look at the Org-mode manual before proceeding. Code blocks in supported languages can occur anywhere in an Org-mode file. Code blocks can be entered directly into the Org-mode file, but it is often easier to enter code with the function org-edit-src-codewhich is called with the keyboard shortcut, C-c '.
This places the code block in a new buffer with the appropriate mode activated. For example, a code block of ruby code looks like this in an Org-mode file:. Babel executes code blocks for interpreted languages such as shell, python, R, etc. You control what is done with the results of execution.
Here are examples of code blocks in three different languages, followed by their output. If you are viewing the Org-mode version of this document in Emacs, place point anywhere inside a block and press C-c C-c to run the code 1 and feel free to alter it!
Babel provides two fundamentally different modes for capturing the results of code evaluation: functional mode and scripting mode. The choice of mode is specified by the :results header argument.

The 'result' of code evaluation is the value of the last statement in the code block. In functional mode, the code block is a function with a return value. The return value of one code block can be used as input for another code block, even one in a different language. In this way, Babel becomes a meta-programming language. If the block returns tabular data a vector, array or table of some sort then this will be held as an Org-mode table in the buffer.
This setting is the default.Python + Org-mode for fluent output generation of scientific research
Notice that, in functional mode, the output consists of the value of the last statement and nothing else. In scripting mode, Babel captures the text output of the code block and places it in the Org-mode buffer. It is called scripting mode because the code block contains a series of commands, and the output of each command is returned.
Unlike functional mode, the code block itself has no return value apart from the output of the commands it contains. Here, scripting mode returned the text that python sent to stdout. For some languages, such as python, R, ruby and shell, it is possible to run an interactive session as an "inferior process" within Emacs.
