# This Bash script automates updating a TiddlyWiki instance with new or modified content items (Tiddlers). It performs the following steps:
|
|
# 1. Generates a unique timestamp to track updates.
|
|
# 2. Verifies the existence of both the main TiddlyWiki index file and individual Tiddler JSON files, exiting with an error if either is missing.
|
|
# 3. Incor CVs, adds 'created' and 'modified' fields from the unique timestamp to each Tiddler.
|
|
# 4. Imports the updated Tiddlers into the wiki using TiddlyWiki's import command, outputting a temporary HTML file for review.
|
|
# 5. Checks if the import was successful by verifying that the corresponding HTML file has been generated. On success:
|
|
# - Moves the new HTML file to replace the old index file in its original location.
|
|
# - Removes temporary files created during processing.
|
|
# If any step fails, it provides an error message and exits with a non-zero status code.
