Implement renderer test suite
This implements a Markdown / Gemtext suite, testing the entire renderer at complex Markdown documents, containing the entirety of current Markdown features accessible with gmnhg. The test suite can be expanded by adding a pair of .md/.gmi files. Minor bug fixes in JSON/Org metadata parsing where bugs were detected with the test suite are also included in this patch. Fixes #13.

# General text
|
||||
|
||||
Paragraphs are printed verbatim in gmnhg.
|
||||
|
||||
Single newlines (like in this multi-line paragraph) will get replaced by a space, as Gemini specification p. 5.4.1 recommends this for soft-wrapping text by clients.
|
||||
|
||||
Inline formatting bits (like this **bold** text, *emphasized* text, ~~strikethrough~~ text, `preformatted text`) are kept to make sure Gemini readers still have the stylistic context of your text.
|
||||
|
||||
## Blockquotes
|
||||
|
||||
Newlines in blockquote paragraphs, unlike usual paragraphs, aren't replaced with a space. This facilitates appending authorship information to the quote, or using blockquotes to write poems.
|
||||
|
||||
> "Never trouble another for what you can do yourself"
|
||||
> — Thomas Jefferson, 3rd president of the US
|
||||
|
||||
> "Wow, writing comprehensive test suites is hard!"
|
||||
> — Timur Demin, while writing this very test file
|
||||
|
||||
> "Somehow I know these two paragraphs will be broken into two separate
|
||||
> blockquotes by gmnhg. I think my knowledge of that comes from being
|
||||
> the author of this program."
|
||||
|
||||
> — also Timur Demin, in the process of writing this test file
|
||||
|
||||
## Code
|
||||
|
||||
gmnhg will use Gemtext preformatted blocks for that. Markdown alt-text for preformatted blocks is supported, and is used to render alt-text as specified by Gemini spec p. 5.4.3.
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
func main() {
|
||||
println("gmnhg is awesome!")
|
||||
}
|
||||
```
|
||||
|
||||
Preformatted Markdown of course isn't rendered:
|
||||
|
||||
```
|
||||
# I am a test Markdown document
|
||||
|
||||
I contain text in **bold**.
|
||||
```
|
||||
|
||||
## Links
|
||||
|
||||
gmnhg supports links, images, and footnotes. Links are a very interesting topic on itself; see a separate document for those.
|
||||
|
||||
=> links.md separate document
|
||||
|
||||
## Lists
|
||||
|
||||
Definition lists, numbered and ordered lists are all supported in gmnhg. There's also a separate document displaying those.
|
||||
|
||||
=> lists.md separate document
|
||||
|
||||
## Tables
|
||||
|
||||
Markdown tables are supported in gmnhg, and are better displayed by a separate document.
|
||||
|
||||
=> tables.md separate document
|
||||
|
||||
## Headings
|
||||
|
||||
Gemini specification allows up to three heading levels, with an optional space after the last heading symbol, `#`. With Markdown, you get 6; gmnhg will simply print the relevant number of #-s, making the client up to parse more heading levels and keeping context of the source document.
|
||||
|
||||
Since clients like Lagrange treat the fourth and the rest of #-s as heading content, it's best to avoid using H4-H6 in Gemini-aware Markdown entirely. Headings from H3 to H6 are provided below so you can test how your client handles that.
|
||||
|
||||
### Heading 3
|
||||
|
||||
#### Heading 4
|
||||
|
||||
##### Heading 5
|
||||
|
||||
###### Heading 6
|
||||
|
||||
## Misc
|
||||
|
||||
Inline HTML is currently stripped, but HTML contents remain on-screen. This may change in the future.
|
||||
|
||||
> There's currently a bug in gmnhg which prevents it from
|
||||
> stripping HTML in certain scenarios. HTML is noticeably still present
|
||||
> inside <span>blockquotes</span>.

Gemini readers still have the stylistic context of your text.
|
||||
|
||||
## Blockquotes
|
||||
|
||||
Newlines in blockquote paragraphs, unlike usual paragraphs, aren't
|
||||
replaced with a space. This facilitates appending authorship information
|
||||
to the quote, or using blockquotes to write poems.
|
||||
|
||||
> "Never trouble another for what you can do yourself"
|
||||
> — Thomas Jefferson, 3rd president of the US
|
||||
|
||||
> "Wow, writing comprehensive test suites is hard!"
|
||||
> — Timur Demin, while writing this very test file
|
||||
|
||||
> "Somehow I know these two paragraphs will be broken into two separate
|
||||
> blockquotes by gmnhg. I think my knowledge of that comes from being
|
||||
> the author of this program."
|
||||
>
|
||||
> — also Timur Demin, in the process of writing this test file
|
||||
|
||||
## Code
|
||||
|
||||
gmnhg will use Gemtext preformatted blocks for that. Markdown alt-text
|
||||
for preformatted blocks is supported, and is used to render alt-text as
|
||||
specified by Gemini spec p. 5.4.3.
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
func main() {
|
||||
println("gmnhg is awesome!")
|
||||
}
|
||||
```
|
||||
|
||||
Preformatted Markdown of course isn't rendered:
|
||||
|
||||
```
|
||||
# I am a test Markdown document
|
||||
|
||||
I contain text in **bold**.
|
||||
```
|
||||
|
||||
## Links
|
||||
|
||||
gmnhg supports links, images, and footnotes. Links are a very
|
||||
interesting topic on itself; see a [separate document](links.md) for
|
||||
those.
|
||||
|
||||
## Lists
|
||||
|
||||
Definition lists, numbered and ordered lists are all supported in gmnhg.
|
||||
There's also a [separate document](lists.md) displaying those.
|
||||
|
||||
## Tables
|
||||
|
||||
Markdown tables are supported in gmnhg, and are better displayed by a
|
||||
[separate document](tables.md).
|
||||
|
||||
## Headings
|
||||
|
||||
Gemini specification allows up to three heading levels, with an optional
|
||||
space after the last heading symbol, `#`. With Markdown, you get 6;
|
||||
gmnhg will simply print the relevant number of #-s, making the client up
|
||||
to parse more heading levels and keeping context of the source document.
|
||||
|
||||
Since clients like Lagrange treat the fourth and the rest of #-s as
|
||||
heading content, it's best to avoid using H4-H6 in Gemini-aware Markdown
|
||||
entirely. Headings from H3 to H6 are provided below so you can test how
|
||||
your client handles that.
|
||||
|
||||
### Heading 3
|
||||
|
||||
#### Heading 4
|
||||
|
||||
##### Heading 5
|
||||
|
||||
###### Heading 6
|
||||
|
||||
## Misc
|
||||
|
||||
Inline HTML is <span class="bold">currently</span> stripped, but HTML
|
||||
contents remain on-screen. This may change in the future.
|
||||
|
||||
> There's currently a [bug in gmnhg][bug] which prevents it from
|
||||
> stripping HTML in certain scenarios. HTML is noticeably still present
|
||||
> inside <span>blockquotes</span>.
|
||||
|
||||
***
|
||||
|
||||
The Markdown horizontal line above is rendered as triple dashes.

# Links
|
||||
|
||||
gmnhg supports links, images, and footnotes. These are extracted from paragraphs and other block elements recursively.
|
||||
|
||||
As there's no inline links in Gemtext, gmnhg instead renders links blocks after paragraphs. Links blocks are sorted by type: first footnotes, then images, then links, blocks of a distinct type separated by a single newline.
|
||||
|
||||
## Inline links & images
|
||||
|
||||
For inline Markdown links, the text inside the square brackets is used as link title: for instance, the link to Gemini specification along with a link to the current CommonMark spec will generate a block of two links.
|
||||
|
||||
=> https://gemini.circumlunar.space/docs/specification.gmi Gemini specification
|
||||
=> https://spec.commonmark.org/0.30/ CommonMark spec
|
||||
|
||||
gomarkdown works with reference-style links as well. Unused reference links are ignored.
|
||||
|
||||
=> https://github.com/gomarkdown/markdown gomarkdown
|
||||
|
||||
xkcd #1853 serves quite well as an inline image example.
|
||||
|
||||
=> https://imgs.xkcd.com/comics/once_per_day.png xkcd #1853
|
||||
|
||||
Other container elements can contain inline links as well. For instance, this is an example of a link inside a blockquote:
|
||||
|
||||
> OTR has significant usability drawbacks for inter-client mobility.
|
||||
> — XEP-0384
|
||||
|
||||
=> https://xmpp.org/extensions/xep-0384.html XEP-0384
|
||||
|
||||
## Footnotes
|
||||
|
||||
gmnhg supports footnotes, written like this[^1]. Footnotes can use any references, including alphanumeric ones[^2]; alphanumeric references will be replaced with numeric IDs on render.
|
||||
|
||||
[^1]: Footnotes can only consist of a single source line due to a quirk of gomarkdown.
|
||||
[^2]: Footnotes can contain any kind of inline **formatting** paragraphs do. For instance, this is a link to GitHub.
|
||||
|
||||
=> https://github.com GitHub
|
||||
|
||||
This line looks like it would belong to footnote 1, but it actually doesn't, and is therefore treated as a new paragraph.
|
||||
|
||||
## Lists of links
|
||||
|
||||
gmnhg additionally supports a special kind of lists: lists consisting solely of links. For these, content rendering will be skipped entirely, and a links block will be rendered instead.
|
||||
|
||||
### Markdown lists
|
||||
|
||||
Links-only lists can be of any type, but they can only be of level 1. The two lists below will get rendered as links blocks:
|
||||
|
||||
=> https://gemini.circumlunar.space/docs/specification.gmi Gemini specification
|
||||
=> https://github.com/tdemin/gmnhg gmnhg
|
||||
|
||||
=> https://gemini.circumlunar.space/docs/best-practices.gmi Best practices for Gemini implementers
|
||||
=> https://gemini.circumlunar.space/docs/faq.gmi Project Gemini FAQ
|
||||
|
||||
The list below contains other meaningful text in its items, and will get rendered as a regular list:
|
||||
|
||||
* Gemini specification is a must-read for a Gemini developer.
|
||||
|
||||
=> https://gemini.circumlunar.space/docs/specification.gmi Gemini specification
|
||||
|
||||
### Series of links
|
||||
|
||||
A series of inline links in a single paragraph, if the paragraph contains no extra meaningful symbols (aside from spaces and newlines), will also get rendered as a single links block:
|
||||
|
||||
=> https://github.com/tdemin/gmnhg gmnhg
|
||||
=> https://gemini.circumlunar.space/docs/specification.gmi Gemini specification
|
||||
|
||||
This also works for single-link paragraphs:

|
||||
[cmark]: https://spec.commonmark.org/0.30/
|
||||
|
||||
[gomarkdown](https://github.com/gomarkdown/markdown) works with
|
||||
reference-style links as well. Unused reference links are ignored.
|
||||
|
||||
[gmnhg]: https://github.com/tdemin/gmnhg "This link will get entirely ignored"
|

 serves
|

quite well as an inline image example.
|
||||
|

Other container elements can contain inline links as well. For instance,
|

this is an example of a link inside a blockquote:
|

### Markdown lists
|
||||
|

Links-only lists can be of any type, but they can only be of level 1.
|
||||
The two lists below will get rendered as links blocks:
|
||||
|
||||
* [Gemini specification][gemspec]
|
||||
* [gmnhg](https://github.com/tdemin/gmnhg)
|

2. [Project Gemini FAQ](https://gemini.circumlunar.space/docs/faq.gmi)
|
||||
|
||||
The list below contains other meaningful text in its items, and will get
|

# Lists
|
||||
|
||||
Definition lists, numbered and ordered lists are all supported in gmnhg.
|
||||
|
||||
## Definition lists
|
||||
|
||||
The lists of definitions get converted into regular unordered lists, prefixed with a star (`*`) as specified by Gemini spec p. 5.5.2.
|
||||
|
||||
gmnhg
|
||||
* a program to generate a Gemini site from an existing Hugo site
|
||||
* a library converting Markdown to Gemtext, based on gomarkdown
|
||||
|
||||
md2gmn
|
||||
* a program to convert Markdown to Gemtext
|
||||
* a wrapper to the gmnhg library
|
||||
|
||||
## Normal lists
|
||||
|
||||
* This is the first item of an unordered list.
|
||||
* This is its second item.
|
||||
* This is a list item that was using the `+` sign. Gemini readers should see this item as the continuation of the previous list.
|
||||
|
||||
1. This is an ordered list first item.
|
||||
2. This is the second item.
|
||||
|
||||
## Lists containing a sub-list
|
||||
|
||||
As there's no indented list line type in Gemtext, gmnhg will indent these with tabs. The tabs number is equivalent to list level minus one (e.g. single tab for second list level).
|
||||
|
||||
Unordered lists can be children of ordered lists, and vice versa.
|
||||
|
||||
* This item contains a child ordered list.
|
||||
1. This ordered list item should get picked up as regular text.
|
||||
2. Whether or not this looks nicely depends on the client.
|
||||
* This item contains a child definition list.
|
||||
Markdown
|
||||
* an overly complex text markup format invented in 2004 whose sole specification of CommonMark lacks both tables and footnotes
|
||||
* a text format that has zero parsers completely compatible between each other.
|
||||
|
||||
1. This item contains a child unordered list.
|
||||
* This whole list should get treated as plain text by clients.
|
||||
|
||||
## Links of lists
|
||||

||||
A special case of lists consisting solely of links to something is documented in the links test document.

# Tables
|
||||
|
||||
gmnhg uses preformatted text blocks to render ASCII text tables.
