orgformat 2026.6.6.1

* orgformat

This is a utility library for providing functions to generate and
modify [[https://orgmode.org][Org mode]] syntax elements like [[https://orgmode.org/manual/Headlines.html#Headlines][headings]], [[https://orgmode.org/manual/External-links.html][links]], [[https://orgmode.org/manual/Timestamps.html#Timestamps][time-stamps]], or
date-stamps.

** Documentation

You can find the [[http://htmlpreview.github.io/?https://github.com/novoid/orgformat/blob/master/orgformat.html][pydoc documentation in HTML here]]. Sorry for the
default colors of pydoc.

I also consider [[file:orgformat/orgformat_test.py][the unit tests as a good starting point]] to learn about
the features provided.

Just *a few* examples:

#+BEGIN_SRC python
        self.assertEqual(OrgFormat.orgmode_timestamp_to_datetime(
            '<1980-12-31 Wed 23:59>'),
                         datetime.datetime(1980, 12, 31, 23, 59, 0, tzinfo=None))

        self.assertEqual(OrgFormat.apply_timedelta_to_org_timestamp(
            '<2019-11-06 Wed 00:59>', -2.0), '<2019-11-05 Tue 22:59>')

        self.assertEqual(OrgFormat.date(time.strptime('2011-11-02T20:38', '%Y-%m-%dT%H:%M'),

            ),
            '<2011-12-19 Mon 21:55>'
        )

        self.assertEqual(OrgFormat.mailto_link('Bob@example.com'),
                         '[[mailto:Bob@example.com][Bob@example.com]]')

        self.assertEqual(OrgFormat.dhms_from_sec(99999), '1d 3:46:39')

** Installation

This tool needs [[http://www.python.org/downloads/][Python 3 to be installed]].

You can install orgformat stand-alone via [[https://packaging.python.org/tutorials/installing-packages/][pip]]:

: pip3 install orgformat

If you are using a project that is referring to orgformat, this
library usually gets added to the =requirements.txt= file of that
project and installed when you do invoke:

: pip3 install -r requirements.txt

# --- BEGIN SHARED: 0dependencies --- see https://github.com/novoid/screencasts/
[[https://0dependencies.dev][https://0dependencies.dev/0dependencies.svg]] → [[https://0dependencies.dev/][learn more about 0dependencies]]
# --- END SHARED: 0dependencies --- see https://github.com/novoid/screencasts/  

** Changelog

This changelog does not list all commits/changes, just the substantial
ones.

- 2019.11.03.1: Finished moving from Memacs and lazyblorg to a separate library
- 2019.11.06.1:
  - [[https://www.python.org/dev/peps/pep-0484/][Python type annotations]] added for [[https://mypy.readthedocs.io/en/latest/index.html][mypy]] checks
  - Refactoring, simplification, unification:
    - more parameters for =show_time= and =inactive=
    - removed some very basic and so-far unused wrappers for other functions
    - removed functions for detailed parameters that got replaced by more generalized functions
    - renamed some functions
  - Unit tests for all functions ;-)
  - Much [[file:orgformat.html][better documentation]] including examples
  - /Don't worry about these breaking changes/: Memacs and lazyblorg
    (the only projects using this library so far) were adapted
    accordingly and therefore nobody else is affected. *No breaking
    changes like this in the future.*
- 2019.12.28.1: =generate_heading()=
- 2019.12.29.1:
  - =date()=, =strdate()=: added =repeater_or_delay=
  - =generate_headining()=: added =scheduled_timestamp= and =deadline_timestamp=

** History

This file was initially written mainly by https://github.com/awieser
and was part of [[https://github.com/novoid/Memacs][Memacs]].

As of 2019-10-31, this file is moved to an independent library since
multiple projects are using its functions such as:

- [[https://github.com/novoid/lazyblorg][lazyblorg]]
- [[https://github.com/novoid/appendorgheading][appendorgheading]] is basically a Python wrapper script for
  =generate_headining()= to be used from command line

I am using [[http://www.python.org/dev/peps/pep-0008/][Python PEP8]] and occasionally some ideas from [[http://en.wikipedia.org/wiki/Test-driven_development][Test Driven
Development (TDD)]]. I fancy Python3 with [[https://typing.python.org/en/latest/spec/annotations.html][type annotations]], although I'm
not using them everywhere at the moment. Starting with 2025, I began
to use help from Claude.ai which is a huge improvement, given my lack
of programming practice and knowledge.

After all, each of my tools was developed because I needed its
functionality and could not get it elsewhere - at least to my
knowledge or taste.
