Obsidian Vault to Hugo Content

Lightweight, extensible, zero-dependency CLI written in Python to help us publish obsidian notes with hugo.

It only takes two arguments: The obsidian vault directory (--obsidian-vault-dir) and the hugo content directory (--hugo-content-dir).

python -m obsidian_to_hugo --obsidian-vault-dir=<path> --hugo-content-dir=<path>

It takes care of the following steps:

  • Clears hugo content directory (directory will be deleted and recreated)
  • Copies obsidian vault contents into hugo content directory (.obsidian gets removed immediately after copying)
  • Replaces obsidian wiki links ([[wikilink]]) with hugo shortcode links ([wikilink]({{< ref "wikilink" >}}))
  • Replaces obsidian marks (==important==) with HTML marks (<mark>important</mark>)
  • Want to do more? You can write and register custom filters to dynamically include/exclude content from processing and processors to do whatever you want with the file contents.

Replacement examples

Obsidian Hugo
[[/some/wiki/link]] [/some/wiki/link]({{< ref "/some/wiki/link" >}})
[[/some/wiki/link|Some text]] [Some text]({{< ref "/some/wiki/link" >}})
[[/some/wiki/link/_index]] [/some/wiki/link/]({{< ref "/some/wiki/link/" >}})
[[/some/wiki/link#Some Heading|Some Heading Link]] [Some Heading Link]({{< ref "/some/wiki/link#some-heading" >}})
==foo bar=== <mark>foo bar</mark>

Note For now, there is no way to escape obsidian wiki links. Every link will be replaced with a hugo link. The only way to get around this is changing the wiki link to don't match the exact sytax, for example by adding an invisible space (Obsidian will highlight the invisible character as a red dot). However, this still is really really not best practice, so if anyone wants to implement real escaping, please do so.

Python API

from obsidian_to_hugo import ObsidianToHugo

obsidian_to_hugo = ObsidianToHugo(
    obsidian_vault_dir="path/to/obsidian/vault",
    hugo_content_dir="path/to/hugo/content",
)

obsidian_to_hugo.run()

Filters

You can pass an optional filters argument to the ObsidianToHugo constructor. This argument should be a list of functions.

The function will be invoked for each file from the obsidian vault that is copied into the hugo content directory.

Inside the function, you have access to the file path and the file contents.

When the function returns False, the file will be skipped and not copied into the hugo content directory.

from obsidian_to_hugo import ObsidianToHugo

def filter_file(file_contents: str, file_path: str) -> bool:
    # do something with the file path and contents
    if your_condition:
        return True # copy file
    else:
        return False # skip file

obsidian_to_hugo = ObsidianToHugo(
    obsidian_vault_dir="path/to/obsidian/vault",
    hugo_content_dir="path/to/hugo/content",
    filters=[filter_file],
)

obsidian_to_hugo.run()

Processors

You can pass an optional processors argument to the ObsidianToHugo constructor. This argument should be a list of functions.

The function will be invoked for each file from the obsidian vault that is copied into the hugo content directory. It will be passed the file contents as string, and should return the processed version of the file contents.

Custom processors are invoked after the default processing of the file contents.

from obsidian_to_hugo import ObsidianToHugo

def process_file(file_contents: str) -> str:
    # do something with the file contents
    return file_contents

obsidian_to_hugo = ObsidianToHugo(
    obsidian_vault_dir="path/to/obsidian/vault",
    hugo_content_dir="path/to/hugo/content",
    processors=[process_file],
)

obsidian_to_hugo.run()
