Wikikdot to Markdown Convertor

Command line convertor from Wikidot syntax to Markdown syntax.

Most format features are translated to standard Markdown. Some specific nonstandard format features are converted to Obsidian markdown extensions.

Inspired by https://github.com/vLj2/wikidot-to-markdown.

Usage

To convert a single file:

python3 convert.py --input|-i INPUT_FILE [--output|-o OUTPUT_DIR]

To convert all files in an input directory:

python3 convert.py --input|-i INPUT_DIRECTORY [--mask|-m MASK] [--output|-o OUTPUT_DIR]

Arguments:

--input INPUT or -i INPUT: path to file or directory to be converted. If it contains spaces, it should be included in quotes: -i "C:\My documents\some wikidot file.txt". Required.

If INPUT is file, this file will be converted and placed to OUTPUT_DIR. If INPUT is directory, all files in this directory and all its subdirectories, that fits MASK, will be converted and placed to OUTPUT_DIR.

The converted file(s) has the same name(s) as input file(s) and ".md" extension.

--output OUTPUT_DIR or -o OUTPUT_DIR: directory where converted file will be placed. Optional. Default is "output" subdirectory. If directory does not exist, it is created.

--mask MASK or -m MASK: mask to select files to convert. Is used only if INPUT is directory. Optional. Default is ".txt".

--overwrite or -w: allows rewriting existing output file. If not specified, and the output file already exists, program stops with error.

Be aware of that while input directory is searched recursively, output files are placed in OUTPUT_DIR without subdirectories, that can cause conflicts.

--rn2n or -n: don't include \r in line endings on Windows (use Unix style)

Supported Format Features

The following features can be converted:

• headers of up to 4 levels

• plain formatting of bold, italic, bold italic, underlined, strikethrough, monospace, ^super- and _sub- script text.

• newlines are preserved like in Wikidot:

Some text
new line in the same paragraph

New paragraph

• simple hyperlinks (like https://github.com/IlyaOvodov/wikidot2markdown) and hyperlinks with text like this

• links to other documents like [[README]] or [[README | read me]]

  NB: it uses Wikiref syntax used by Obsidian.

• anchors and links to anchors. Anchors are not standard Markdown features and here they are implemented in Obsidian's manner like ^{^myanchor} at the end of paragraph.

• inline code

• code blocks, including language specification:

def f(a):
    return a+1

• math formulae: inline ($\alpha=1$) and block formulae, including tags:

$$ \tag{eq1} |x| = 123 $$

• references to equations ([[^eq1 | 1]])

NB: equation auto-numbering is not supported. All equation tags are converted to anchors named as eq.

• pictures defined by URL:

  

• pictures from local file:

![[sample.jpg]]

NB: it uses Wikiref syntax used by Obsidian.

• tables:

Head1	Head2	Head2
X	0
X	X	X
0		0

NB: Wikidot allows table row to have more cells than header. In Markdown extra cells are not displayed. This situation is not handled in any way during conversion.
