Ready for release 1.16

The "toc" subcommand now takes filenames
In order to make use of the shell's file-completion, the command now takes filenames. These end in '.md'. Previously, that resulted in errors such as "Cannot load index.md: open index.md.md: no such file or directory".

 ### Filenames and URL path

-One of the sad parts of the code is the distinction between path and
-filepath. On a Linux system, this doesn't matter. I suspect that it
-also doesn't matter on MacOS and Windows because the file systems
-handle forward slashes just fine. The code still tries to do the right
-thing. A path that is derived from a URL is a path with slashes.
-Before accessing a file, it has to be turned into a filepath using
-`filepath.FromSlashes` and in the rare case where the inverse happens,
-use `filepath.ToSlashes`. Any path received via the URL path uses
-slashes and needs to be converted to a filepath before passing it to
-any `os` function. Any path received within a `path/filepath.WalkFunc`
-is a filepath and needs to be converted to use slashes when used in
-HTML output.
+There are some simplifications made. The code doesn't consider the

+In an ironic reversal of priorities, this theme uses JavaScript to

Alex Schroeder	a5421372d8	Set explicit timeouts Read timeout: 2 min (the client has two minutes to upload all its files). Write timeout: 5 min (the server has five minutes to process all the files). Idle timout: 2 min (the client has two minutes to make a new request without needing to do another TLS handshake).	2025-03-24 17:41:22 +01:00
Alex Schroeder	7017363f6a	Fix upload error at the top directory Skipping filepath.Clean resulted in the empty string for the top directory, so that all file uploads failed. This commit fixes that.	2025-03-16 23:16:34 +01:00

Alex Schroeder	7d748f82da	Add the default templates to the tarballs	2025-03-14 01:01:10 +01:00
Alex Schroeder	8385bc424a	Improving path vs filepath code Rename the "path" argument to "name" if it refers to a page name (i.e. a path) or "fp" if it refers to a filepath. Don't escape Page.Name when ready to render a HTML template because in some case this means unescaping in functions. New method isHiddenName to replace ad-hoc checks for "." prefixes and the like.	2025-03-14 00:56:40 +01:00
Alex Schroeder	820763bf23	Change {{.Name}} to {{.Path}} in HTML templates This is a major change for anybody who has templates. In order to handle the encoding of directory and filenames correctly for uploads, page.Base() was added. It required at url.PathUnescape because it uses page.Name and that used to be escaped before rendering. Instead of doing that, there's now the actual .Name (unescaped) and .Path (escaped). This change is only necessary if the name contains characters that the html/template doesn't escape for encodePathSegment: semicolon, comma and question-mark. We can ignore the forward-slash because we don't allow that in page names.	2025-03-12 09:29:38 +01:00
Alex Schroeder	7d40fa4adb	Use nameEscape for all redirects Redirects don't use templates and therefore don't escape the path names.	2025-03-12 08:35:24 +01:00
Alex Schroeder	6e24603c27	Add some more Umlaut tests	2025-03-11 09:27:56 +01:00
Alex Schroeder	5096627b87	Unescape the base name of the page This still feels wrong. Is the p.Name not always unescaped?	2025-03-11 09:26:57 +01:00
Alex Schroeder	0c691123ff	Test the redirect with Umlauts Surprisingly, this uses the unescaped path and that doesn't look right. Then again, it's an IRI instead of an URI and perhaps that's OK, too.	2025-03-11 09:25:51 +01:00

Alex Schroeder	58249aac85	Change MICRO SIGN to GREEK SMALL LETTER MU 😭	2025-03-05 20:05:38 +01:00
Alex Schroeder	1fdd502e95	Fix upload templates for themes Note that webp images can be written, too.	2025-02-23 00:15:05 +01:00
Alex Schroeder	196ff605c3	Rewrite file uploading Converting now happens not only when images are resized by setting the max width. Setting the quality or changing the file extension also results in conversion. Previously, it was possible to upload a JPEG file and save it using a PNG filename -- but the file itself was still JPEG encoded!	2025-02-23 00:08:43 +01:00
Alex Schroeder	6c1e595f13	Add minimal after uploading HEIC and WebP image	2025-02-22 21:49:53 +01:00
Alex Schroeder	34fdb5d9a9	Add WebP support for uploading and resizing	2025-02-22 21:46:47 +01:00
Alex Schroeder	b28614fa52	Fix README The HEIC library is a WASM blob that no longer prevents cross-compilation. Blows my mind but here we are.	2025-02-11 19:05:44 +01:00
Alex Schroeder	e7511ed059	Update templates of transjovian.org theme Upload handling multiple files to add to the original page instead of just the last one.	2025-02-09 14:31:47 +01:00
Alex Schroeder	a5d03dd136	Update templates of alexschroeder.ch theme Added preview button. Search with image previews. Upload handling multiple files to add to the original page instead of just the last one.	2025-02-09 14:16:37 +01:00

Alex Schroeder	c9bb062a04	Plain theme Add support for rocket links, Gemini style. Add an index.md file so that the Home link works.	2025-02-09 13:20:42 +01:00
Alex Schroeder	e2eec5e052	Chat theme Better support for lists. Add an index.md file so that the Home link works.	2025-02-09 13:20:42 +01:00
Alex Schroeder	26033de177	Update release-information	2025-02-09 11:46:35 +01:00
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
Alex Schroeder	e90ff9e7dd	Fix timestamp handling for backup files The timestamp has to be updated!	2024-11-16 11:45:24 +01:00
Alex Schroeder	70356e850a	Fiddle with case for the headings	2024-11-16 11:37:09 +01:00

Alex Schroeder	52d6f26eed	Add unreleased 0.15 to the docs	2024-11-15 19:28:46 +01:00
