Niels Lohmann a47170346a docs: new design for the documentation site (#5934)
* docs: new design for the documentation site

Apply the brand to the Material for MkDocs site: Inter and JetBrains Mono
served by the site (upright and real italic), brand colours, blue header band
with the syntax pattern, wordmark in the header, new home page (hero, cards,
animated feature tour), 404 page, polish for tabs, search, footer, focus
rings, tables and code blocks, and theme features (code copy, previous/next
footer, TOC follow, search suggestions).

Draw the number railroad diagram, the parser callback events and the iterator
illustrations as inline SVGs that follow the light and dark scheme. The
generator scripts are in docs/mkdocs/scripts/figures; the feature slideshow
(json-light.svg, json-dark.svg, replacing json.gif on the home page) is built
by docs/mkdocs/scripts/slideshow. Decision nodes in five flowcharts become
hexagons, which need far less room.

* docs: add figures, table captions and a macro chooser

- Figures with numbered captions: SAX stepper, json_view layout and edit
  stepper, exception map, JSON pointer and patch walkers, QA pipeline,
  scaling and binary size charts, roadmap lanes, release timeline,
  integration decision tree and namespace builder
- Table captions (nj-table-caption) on 9 pages
- Compile times: modules and PCH charts, filesystem section, re-measured
  Figure 1, links between features/modules.md and compile_times.md
- Interactive macro chooser for features/arbitrary_types.md
- Link check: exclude URLs that answer the plugin with 400/401/419 or are
  dead (customers.md)

* docs: macro chooser generates adl_serializer for non-default-constructible types

Signed-off-by: Niels Lohmann <mail@nlohmann.me>

* docs: cross-link concept pages and API pages in See also sections

Add See also links in both directions between the concept pages (features,
home, integration) and the API pages, write API links in code font, give every
entry a comment after a dash, and show the callback event figure on the parser
callbacks page.

* docs: address review comments on the new design

- Home: add a "Latest release" button
- Sponsors: update the list and group it by tier
- Features: list all feature pages on the index page
- Releases: add highlights per release, link the 4.0 roadmap, add the first commit to the timeline
- Exceptions: prefix all example messages with the exception name
- API: no code font for format names in the See also links of the to_/from_ pages
- Merge Patch: show the document before, the patch, and the result
- Replace "--" with typographic dashes, mark external links with an icon, center Mermaid diagrams

nlohmann::json_pointer::operator/

// (1)
json_pointer operator/(const json_pointer& lhs, const json_pointer& rhs);

// (2)
json_pointer operator/(const json_pointer& lhs, string_t token);

// (3)
json_pointer operator/(const json_pointer& lhs, std::size_t array_idx);
  1. create a new JSON pointer by appending the right JSON pointer at the end of the left JSON pointer
  2. create a new JSON pointer by appending the unescaped token at the end of the JSON pointer
  3. create a new JSON pointer by appending the array-index-token at the end of the JSON pointer

Parameters

lhs (in)
JSON pointer
rhs (in)
JSON pointer to append
token (in)
reference token to append
array_idx (in)
array index to append

Return value

  1. a new JSON pointer with rhs appended to lhs
  2. a new JSON pointer with unescaped token appended to lhs
  3. a new JSON pointer with array_idx appended to lhs

Exception safety

Strong guarantee: if an exception is thrown, there are no changes to any JSON pointer. The operands are not modified; a new JSON pointer is built from a copy of lhs.

Complexity

  1. Linear in the length of lhs and rhs.
  2. Linear in the length of lhs.
  3. Linear in the length of lhs.

Examples

??? example

The example shows the usage of `operator/`.
 
```cpp
--8<-- "examples/json_pointer__operator_add_binary.cpp"
```

Output:

```json
--8<-- "examples/json_pointer__operator_add_binary.output"
```

  • push_back - append an unescaped token at the end of the pointer

Version history

  1. Added in version 3.6.0.
  2. Added in version 3.6.0. Changed type of token to string_t in version 3.11.0.
  3. Added in version 3.6.0.
