History: Converting from Tiki syntax to Markdown

            ! {{page}}

New in ((Tiki25)) and improved in ((Tiki26)): Native support for ((Tiki-Flavored Markdown)). But what if you have content in Tiki syntax?

^ As of 2023-09, this is still Beta. You should first use on a test database, and review results before running on a production database. It is not yet ready to be ran on *.tiki.org sites (which do have a huge quantity of diverse content).

We are testing on:
* https://markdownthemes.tiki.org
* https://markdowndoc.tiki.org/
* https://markdowndev.tiki.org/

Please see the evolution: https://gitlab.com/tikiwiki/tiki/-/commits/master?search=markdown

As of 2023-08-02, a root cronjob is ran on /root/predogfood.sh which contains
{CODE()}
# markdownthemes.tiki.org
echo "========== markdownthemes.tiki.org ============"
cd /opt/tiki-manager/app/
php tiki-manager instance:clone --source=2 --target=9 --no-interaction --direct --skip-reindex --skip-cache-warmup --only-data -vv
php tiki-manager instance:update --instances=9 --no-interaction --skip-reindex --skip-cache-warmup --stash -vv
php tiki-manager.php instance:profile:apply --instances=9 --profile=Markdown_Settings --no-interaction -vv
php tiki-manager.php instance:maintenance --instances=9 on

cd /home/tiki-markdownthemes/public_html
php8.1 console.php markdown:convert --markdown --save -vv
php8.1 console.php plugin:refresh -vv
php8.1 console.php plugin:approve --all -vv
php8.1 console.php user:password admin (redacted) -vv
php8.1 console.php index:rebuild --log -vv

cd /opt/tiki-manager/app/
php tiki-manager.php instance:maintenance --instances=9 off
{CODE}

!! Test what conversion will do
This will show conversion in the command line interface.
{CODE()}
php console.php markdown:convert --markdown
{CODE}

!! Do the actual conversion
You should first do this on a test backup instance.
{CODE()}
php console.php markdown:convert --markdown --save
{CODE}


!! Notes
* ((MakeTOC)) has been deprecated and is not available in Markdown. Please use ((PluginAutoTOC)) instead.
* Some content can't be automatically converted so you'll have to do manually (it will be indicated)
* We extended Markdown
