[1t] API functions#


rivt has seven API functions. The name rivt is an acronym taken from the four functions that process content.

Content APIs
  1. [R]un executes shell commands.
  2. [I]nsert adds static table, image, equation and text content.
  3. [V]alues evaluates equations and functions.
  4. [T]ools runs reStructuredText, HTML, LaTeX and Python scripts.
The remaining three functions are used for document generation and debugging. Publish APIs
  1. Doc specifies the doc type and style.
  2. Skip can be used for interactive debugging and comments.
  3. Exit can be used for interactive debugging.

API Function

Name

Purpose

rv.R (rS)

Run

Run shell commands

rv.I (rS)

Insert

Insert static sources

rv.V (rS)

Values

Calculate values

rv.T (rS)

Tools

Python and markup scripts

rv.D (rS)

Doc

Publish docs

rv.S (rS)

Skip

Skip section (comments and debugging)

rv.X (rS)

Exit

Exit rivt (debugging)

If interactive IDEs like VSCode or Spyder are used to edit and run rivt files, each API function can be processed as a cell (similar to Jupyter Notebooks) by using the standard prefix notation:

# %% optional label
rv.API_FUNCTION("""rivt string""")

[2t] rivt string#


Each API function takes a triple quoted rivt string argument composed of two parts - a header substring followed by a content substring.

The first line of the rivt string is a header substring that defines section processing. It is followed by a content substring that includes rivt markup. The content substring is indented four spaces for improved readability and section folding.

Header substring


The header substring starts with a section label followed by vertical bar that deliniates three comma separated section parameters that can override default behavior. The section label is the section title.

rv._("""Section Label | doc;stored, private;public, section;merge

     Content substring indented 4 spaces

    ...

    """)

The parameters include the following, in any order:

private/public

Determines whether the API section text is copied to the the /public folder rivt file for sharing.

doc/stored

Determines whether the rivt string is formatted and printed in the doc, or just annotated in the doc and written to a file in the Stored folder for optional inclusion as an appendix.

section/merge

Determines whether the API starts a new doc section or is merged into the previous section.

Default settings in the header substring do not need to be specified. The default setting for each API is listed first (in bold) in the table below.

Examples of header substring settings are shown below.

  • An example with explicit defaults (they do not have to be declared).

# This

rv.I("""A New Section | private, doc, section

    Content text
    ...

    """)

# is equivalent to:

rv.I("""A New Section

    Content text

    ...

    """)
  • An example that merges a section into the previous section.

rv.I("""A Merged Section | merge

    Content text

    ...

    """)

Content substring


The content substring is indented four spaces for legibility and code folding. It includes line tags, block tags and commands along with text.

rv._("""Section Label

    Content text indented 4 spaces.
    ...

    """)

Content is converted line by line into formatted text and RestructuredText, and then further processed into HTML or PDF. If a line does not contain a command or tag it is passed through as is, which allows for the Insert function (rv.I) including some restructured text directly i.e. surrounding words with * or ** will format a word as italic or bold respectively.

In addition block tags in the Tools function (rv.T) directly supports processing HTML, LaTeX and reStructuredText scripts.

[3t] Tags and Commands#


Line Tags

A line tag formats a line of text and is denoted with a single _[LETTER], placed at or near the end of the line, depending on the tag.

Block Tags

A block tag formats a block of text and begins with _[[TAGNAME]] and terminates with _[[END]].

Commands

rivt commands read and write external files. They typically start in the first column with a vertical bar ( | ) followed by the command name, file path, and parameters.

The exceptions are, the definition (=:), the assignment (<=:) and the compare (<>) commands, which are used to define, assign and compare values.

| COMMAND | relative path | parameters

File paths are specified relative to the rivt root folder. The rivt report folder structure is described here..

If the path is ommitted the default path for each command is applied. If the singledoc parameter is set, the resource files and docs are stored in the rivt root folder.

Tag and Command syntax for each API type is defined and described using the following format:

Markup Key

_[TAG] or | COMMAND |


Description

    Syntax:
        _[TAG] or | COMMAND | syntax

    Example:
        This is a sentence. _[C]

[4t] Folders#


Folders provide standard file locations that simplify doc and report generation.

Folder Key
- Required names or prefixes are shown in brackets [ ].
- Folders (including subfolders) that contain author generated files are marked with a single vertical bar ( | ).
- Folders (including subfolders) that contain *rivtlib* generated files are marked with double vertical bars ( || ).
