Update release-information

Don't link hashtags in link text
This change depends on a change to the markdown library. Specifically, the parser's InsideLink must be public. This means that the #like_this hashtag from the README.md in the source directory is no longer available, so that test had to be rewritten. Another change to reduce the number of false hashtags was to use the hashtag parser for all situations: It's also used to identify hashtags in the search query string. The parser doesn't automatically turn the matches to lower-case, however, so that has to be done when indexing documents and when searching for hashtags. The hashtags command for the commandline no longer prints a hash for all the tags.

+
+# NAME
+
+oddmu-export - export all pages into one file
+
+# SYNOPSIS
+
+*oddmu export* [*-template* _filename_]
+
+# DESCRIPTION
+
+The "export" subcommand prints a RSS file containing all the pages to stdout.
+You probably want to redirect this into a file so that you can upload and import
+it somewhere.
+
+Note that this only handles pages (Markdown files). All other files (images,
+PDFs, whatever else you uploaded) are not part of the feed and has to be
+uploaded to the new platform in some other way.
+
+The *-template* option specifies the template to use. If the template filename
+ends in _.xml_, _.html_ or _.rss_, it is assumed to contain XML and the optional
+XML preamble is printed and appropriate escaping rules are used.
+
+# FILES
+
+By default, the export uses the **feed.html** template in the current directory.
+
+# EXAMPLES
+
+Export all the pages into a big XML file:
+
+```
+env ODDMU_LANGUAGES=de,en oddmu export > /tmp/export.xml
+```
+
+Alternatively, consider a template file like the following, to generate a JSON
+feed. The rule to disallow a comma at the end of arrays means that we need to
+add an empty tag and an empty item, unfortunately:
+
+```

+oddmu-webdav - how to setup Web-DAV using Apache for Oddmu
+.PP
+.SH DESCRIPTION
+.PP
+With the Apache Web-DAV module enabled, users can mount the wiki as a remote
+file system and edit files using their favourite text editor.\& If you want to
+offer users direct file access to the wiki, this can be accomplished via ssh,
+sftp or Web-DAV.\&
+.PP
+The benefit of using the Apache Web-DAV module is that access has to be
+configured only once.\&
+.PP
+.SH CONFIGURATION
+.PP
+In the following example, "data" is not an action provided by Oddmu but an
+actual directory for Oddmu files.\& In the example below,
+"/home/alex/campaignwiki.\&org/data" is both the document root for static files
+and the data directory for Oddmu.\& This is the directory where Oddmu needs to
+run.\& When users request the "/data" path, authentication is required but the
+request is not proxied to Oddmu since the "ProxyPassMatch" directive doesn'\&t
+handle "/data".\& Instead, Apache gets to handle it.\& Since "data" is part of all
+the "LocationMatch" directives, credentials are required to save (PUT) files.\&
+.PP
+"Dav On" enables Web-DAV for the "knochentanz" wiki.\& It is enabled for all the
+actions, but since only "/data" is handled by Apache, this has no effect for all
+the other actions, allowing us to specify the required users only once.\&

+```
+
+In order for this to work, you must enable the mod_dav_fs module. This
+automatically enables to the mod_dav module, too. Restart the server after
+installing enabling a module.
+
+```
+sudo a2enmod mod_dav_fs
+sudo apachectl restart
+```
+
+Check the permissions for the data directory. If the Oddmu service uses the
+"oddmu" user and Apache uses the "www-data" user, you could add the data
+directory to the "www-data" group and give it write permissions:
+
+```
+sudo chown oddmu:www-data /home/alex/campaignwiki.org/data/knochentanz
+sudo chmod g+w /home/alex/campaignwiki.org/data/knochentanz
+```
+
+# EXAMPLES
+
+Web-DAV clients are often implemented such that they only work with servers that
+exactly match their assumptions. If you're trying to use _gvfs_(7), the Windows
+File Explorer or the macOS Finder to edit Oddmu pages using Web-DAV, you're on
+your own.
+
+This section has examples sessions using tools that work.
+
+## cadaver
+
+Here's how to use _cadaver_(1). The "edit" command uses the editor specified in
+the EDITOR environment variable. In this example, that's
+"emacsclient --alternate-editor= ".
+
+```
+cadaver https://campaignwiki.org/data/knochentanz/

+
+## curl and hdav
+
+Here's how to use _curl_(1) to get the file from the public "/view" location and
+how to use _hdav_(1) to put the file to the protected "/data" location. In this
+example, _ed_(1) is used to append the word "test" to the file.
+
+```

+## davfs2
+
+Here's how to use _davfs2_(1) using _mount_(1). Now the whole wiki is mounted
+and can be edited like local files. In this example, _echo_(1) and redirection
+is used to append the word "test" to a file.
+
+```

+## Using the priviledged port 80
+
+When running a personal wiki, you can have the oddmu binary listen on port 80,
+the standard HTTP port. It is not really worth the effort: It means that you can
+visit "http://localhost/" instead of "http://localhost:8080". Nevertheless, if
+you're interested in giving it a try, here's how to do it.
+
+The service definition must specify the new port:
+
+Environment="ODDMU_PORT=80"
+
+Since this is a privileged port, the binary needs an extra capability for an
+ordinary user to do this.
+
+```
+sudo setcap 'cap_net_bind_service=+ep' oddmu
+```
+
+Note that as soon as you recompile, the capability is gone again and the above
+must be repeated.
+
+# SECURITY
+
+Only allow direct access to Oddmu on systems and networks where you're OK with
+every user editing the pages. On the open web, this is not true. If your server
+is on the open web, always run Oddmu behind a regular web server acting as a
+reverse proxy, limiting regular visitors to read-only access. This means that
+the regular web server listens on the regular privileged ports (80 for HTTP,
+443 for HTTPS) and passes requests to Oddmu on some other port.

+Plain theme
+===========
+
+This makes it look as if the site consists mostly of editable plain
+text. Accordingly, the user interface has been simplified and there
+are no links to the preview, add, diff and upload actions and the
+corresponding templates have been deleted. There is no special static
+or feed template (mostly because the feed would depend on the list of
+links that isn't rendered).
+
+Now, the text is still saved in Markdown files and the Markdown is
+still rendered to HTML – but the "view" template just prints the page
+body inside a "pre" block and ignores the rendered HTML.
+
+This being text files, there are also no links to follow. That is why
+there's no link here back to themes. Sorry!
+
+This also means that you can only edit new files by editing the URL in
+the address bar of your browser since you can't link to them.

Alex Schroeder	e1ba007f97	Don't link hashtags in link text This change depends on a change to the markdown library. Specifically, the parser's InsideLink must be public. This means that the #like_this hashtag from the README.md in the source directory is no longer available, so that test had to be rewritten. Another change to reduce the number of false hashtags was to use the hashtag parser for all situations: It's also used to identify hashtags in the search query string. The parser doesn't automatically turn the matches to lower-case, however, so that has to be done when indexing documents and when searching for hashtags. The hashtags command for the commandline no longer prints a hash for all the tags.	2025-02-07 20:05:36 +01:00

There is no cross-compiling available. If only somebody wrote a HEIC decoder in pure Go.	2024-08-23 17:24:23 +02:00

Alex Schroeder	5f8e006594	Fixing export and missing subcommands Both of these subcommands rely on the global index. Loading this global index and acting upon it while tests are running is problematic, however. Walking that index results in being unable to load files that are being created and deleted in other tests. Therefore, these tests get their own minimal index that only indexes the Markdown files in the original checkout: README.md, index.md, and the Markdown files in the the "themes" tree. This also means that missingCli and exportCli must accept a pointer to an index and use that instead of the global index. Add a test for language in the export feed. Add a test for a JSON feed. Both of these tests used to fail because the exportCli funtion did not copy p.Body to it.Body so when the template calls .Languages the result was always empty.	2024-08-16 18:27:34 +02:00
