panvimwiki 0.3.1

Vimwiki Diary tools for conversion to Microsoft Word docx.

Filter and convert Vimwiki notes using pandoc

Introduction

Panvimwiki provides tools for conversion to Microsoft Word docx or other output formats supported by Pandoc. Panvimwiki provides command line tools as well as Vim commands to concatenate and convert Diary Notes or convert any Vimwiki note.

Installation

Panvimwiki requires Pandoc. Installation with conda is recommended because the system version, e.g., with Ubuntu, may be too old. Or download from the website.

Using the Vim 8 native packages, panvimwiki should install in pack/*/opt/panvimwiki because it depends on :python3 and requires installation of the python package panvimwiki.

From a bash shell, enter the following:

# Adjust dest to suit, e.g., $HOME/vimfiles/pack/vimwiki/opt/panvimwiki
dest="$HOME/.vim/pack/vimwiki/opt/panvimwiki"

git clone https://github.com/jfishe/panvimwiki.git "$dest"

# Activate the python environment used by Vim.
# Then install panvimwiki in that python environment.
python -m pip install "$dest"

Panvimwiki requires Vim compiled with Python 3, so add the following to vimrc prior to :filetype-plugin-on. See :packadd for an explanation. Otherwise, install panvimwiki in pack/*/start/panvimwiki.

if has('python3')
  packadd! panvimwiki
endif

Command Line Shell

Panvimwiki provides plain text pre-filters and pandoc filters for use from the command line.

For example from a bash prompt:

cat $HOME/vimwiki/diary/* |
    delete_bullet_star |
    delete_task_pending |
pandoc --from=vimwiki --to=markdown \
    --filter=delete_tag_lines \
    --filter=delete_taskwiki_heading \
    --filter=delete_empty_heading

From python:

from pathlib import Path
from panvimwiki.convert import convert

PREFILTER = (
    "delete_bullet_star",
    "delete_task_pending",
)
FILTER = (
    "delete_tag_lines",
    "delete_empty_heading",
    "delete_taskwiki_heading",
)
EXTRA_ARGS = (
    "--shift-heading-level-by", "1",
    "--data-dir", str(Path.home() / "vimwiki_html/templates"),
)

convert(
    inputfile=str(Path.home() / "vimwiki/index.wiki"),
    outputfile=str(Path.home() / "vimwiki_html/markdown/index.md"),
    to="markdown",
    prefilters=PREFILTER,
    filters=FILTER,
    extra_args=EXTRA_ARGS,
)

Pre-Filters

delete_bullet_star

Remove unordered lists which use the star (asterisk) bullet marker. The pre-filter does not remove task list items (see delete_task_pending). The pre-filter does not handle wrapped bullets--i.e., it will delete the bulleted-line and leave the wrapped lines. I haven't figured out a good regex for wrapped lines.

echo '- Bulleted list item 1 should appear\n' \
     '* Bulleted list item 6 should NOT appear' |
delete_bullet_star

- Bulleted list item 6 should NOT appear

delete_task_pending

Delete pending tasks.

echo '- [ ] Bulleted list done0 item 0 should NOT appear' \
     '- [.] Bulleted list done1 item 1 should appear' |
delete_task_pending

- [.] Bulleted list done1 item 1 should appear

Pandoc Filters

Panvimwiki provides plain text pre-filters and pandoc filters for use from the command line.

delete_tag_lines

Delete lines which only contain Vimwiki tags, e.g., ':tag1:tag2:'

delete_empty_heading

Remove headings that do not have any children or paragraphs. Remove tag lines first, delete_tag_lines or the heading is not considered empty.

delete_taskwiki_heading

Commands

Local Commands

These commands are only available (and meaningful) when you are currently in a Vimwiki file.

VimwikiConvert[!]

Convert the current Vimwiki buffer. With !, open with default viewer.

Convert the current Vimwiki :buffer to the selected output format (default: docx) specified in g:panvimwiki_settings.format.

Copy the path to the Word file to the clipboard register "+ quoteplus. On Windows Subsystem for Linux (WSL), convert the path from POSIX to Windows before copying to clipboard.

Remove extraneous info:

• Vimwiki tag lines, e.g., :tag1:tag2:
• Not started tasks, e.g., - [ ] Task1
• Non-task bullet lines, e.g., * [[URI|Description]] or * Text
• Remove empty parent/child headings.

VimwikiConvertWeek[!]

Concatentate DiaryNotes for Monday through current buffer and convert. With !, open in default viewer.

After concatenating DiaryNotes for the week, behave as VimwikiConvert.

Settings

Global Settings

g:panvimwiki_settings

Optionally add the following to vimrc or, preferably, '~/.vim/plugin/vimwiki.vim'. Panvimwiki defaults to docx format, without extra_args.

let g:panvimwiki_settings = {
      \ 'extra_args': [ '--shift-heading-level-by', '1',
      \ '--data-dir', '~/vimwiki_html/templates/'
      \ ],
      \ 'format': 'docx'
      \ }

Development and Testing

Because pandoc is required, a conda environment called pyscaffold is created. The default name may be overridden with the --name <environment name> parameter.

git clone https://github.com/jfishe/panvimwiki.git
cd panvimwiki
conda env create --file environment.yml --name pyscaffold
conda activate pyscaffold
pipx install covimerage

Covimerage has conflicting dependencies, so pipx creates an isolated executable in ~/.local/bin. You may want to run pipx uninstall covimerage to avoid cluttering $PATH.

tox -av # List tox commands and descriptions.
tox --recreate # Build the package and run tests with python and Vader.
tox -e vim # Run Vader tests and generate coverage report.
# Run Vader tests and view results with Vim.
vim -Nu tests/vim/vimrc -c 'Vader tests/vim/*.vader'

Note

This project has been set up using PyScaffold 4.3. For details and usage information on PyScaffold see https://pyscaffold.org/.
