```cpp

The type used for the initializer-list [constructor](basic_json.md) (overload 5) and for functions
|
||||
such as [`operator=`](operator=.md) that accept a braced-init-list of JSON values. Each element wraps a
|

`basic_json` value or something convertible to one, deferring the decision of whether the list should be
|
||||
parsed as a JSON array or a JSON object to the constructor itself.

|

The comparator used to determine key equality when looking up elements. Unlike `std::map`, `ordered_map`
|

uses linear search with `key_compare` rather than an ordering relation, since element order reflects
|

insertion order rather than key order.

Since C++14, the transparent `#!cpp std::equal_to<>` is used, which enables heterogeneous lookup (e.g.

looking up by a `#!cpp const char*` key without constructing a temporary `Key`).

# Public API Policy
|
||||
|
||||
This document defines what counts as the **public API** of nlohmann/json for the purposes of the
|
||||
`tools/api_checker/` tooling, what stability is (and is not) guaranteed, and how API changes are
|
||||
classified as breaking or feature additions. It exists so that "public API" is a checkable, mechanical
|
||||
property of the source, not a matter of convention or memory — see
|
||||
[Discussion #3691](https://github.com/nlohmann/json/discussions/3691) for the original motivation.
|
||||
|
||||
## What counts as public API
|
||||
|
||||
The public API surface is derived from C++ semantics (class templates, access specifiers, namespace
|
||||
scoping) by `extract_api.py`, not from the presence of documentation. It consists of:
|
||||
|
||||
1. **Public members of six class templates**: `basic_json`, `adl_serializer`,
|
||||
`byte_container_with_subtype`, `json_pointer`, `json_sax`, `ordered_map`. Specifically, the *primary
|
||||
template definition* (`CLASS_TEMPLATE` cursor with `is_definition() == True`) — never an implicit
|
||||
instantiation, which silently drops SFINAE-guarded overloads. Two tiers apply:
|
||||
- **Callable tier** (methods, constructors, destructors, conversion operators, function templates):
|
||||
every public callable requires its own `@sa` documentation link, without exception.
|
||||
- **Type tier** (public type aliases): requires `@sa`, except for a fixed exemption list of
|
||||
STL-container named-requirement aliases that mirror standard-library conventions rather than being
|
||||
independently documented: `value_type`, `reference`, `const_reference`, `pointer`, `const_pointer`,
|
||||
`iterator`, `const_iterator`, `reverse_iterator`, `const_reverse_iterator`, `difference_type`,
|
||||
`size_type`, `allocator_type`, `key_type`, `mapped_type`. This list is defined once, in
|
||||
`extract_api.py`'s `stl_exempt` set, and referenced here rather than duplicated.
|
||||
2. **Free functions and operators in `nlohmann::`**, including `nlohmann::literals::json_literals`
|
||||
(the `operator""_json` / `operator""_json_pointer` user-defined literals). Comparison and stream
|
||||
operators on `basic_json` and `json_pointer`, `operator/`, `swap`.
|
||||
3. **The six alias-exposed exception types**: `basic_json::exception`, `parse_error`,
|
||||
`invalid_iterator`, `type_error`, `out_of_range`, `other_error`. These are public `TYPE_ALIAS_DECL`s
|
||||
in `basic_json` (e.g. `using exception = detail::exception;`) whose underlying class is physically
|
||||
defined in `nlohmann::detail::exceptions.hpp`. `extract_api.py` follows the alias to find the `@sa` on
|
||||
the underlying `detail::` class definition, since that's where the existing documentation convention
|
||||
places it. Each exception class is documented as *one page* — its individual members (`what()`, `id`)
|
||||
are not separately tracked, matching the existing one-page-per-class convention.
|
||||
4. **Macros**, governed separately by `docs/mkdocs/docs/api/macros/` (the curated list of ~30 pages is
|
||||
authoritative) and cross-checked, advisory-only, by `check_macros.py`. See "Known limitations" below
|
||||
for why macros can't be checked the same way as everything else.
|
||||
|
||||
## What's excluded
|
||||
|
||||
- **Everything in `nlohmann::detail::`**, with the one narrow exception above (exception-type aliases).
|
||||
**No stability is guaranteed for any symbol in the `detail::` namespace — clients must not rely on it**,
|
||||
regardless of whether a given `detail::` symbol happens to be reachable from user code today. This is
|
||||
an explicit, deliberate policy, not an oversight.
|
||||
- **Private and protected members**, even of the six tracked classes. `extract_api.py` walks non-public
|
||||
members only to check they don't carry a stray `@sa` (a documentation leak) — never to add them to the
|
||||
public surface.
|
||||
- **The ABI inline-namespace segment** (`json_abi_v3_12_0`, `json_abi_diag_v3_12_0`, etc. — see
|
||||
[docs/mkdocs/docs/features/namespace.md](../../docs/mkdocs/docs/features/namespace.md)). This is a
|
||||
version-tag identity concern for `diff_api.py` (it must not make every release look like the entire API
|
||||
was removed and re-added), not a scoping or visibility concern — the symbols inside it are public or
|
||||
not independent of the tag.
|
||||
|
||||
## Breaking vs. feature classification
|
||||
|
||||
`diff_api.py` compares the `public_api` surface of two snapshots using an overload-disambiguating
|
||||
identity — `(scope, identity_name, kind, signature)`, where `signature` is the declaration's own
|
||||
source text (return type, name, parameter list, trailing qualifiers; comments and constructors'
|
||||
member-initializer-lists stripped). This is the third identity scheme this tooling has used; the
|
||||
first two were each found broken by testing against real release tags, not by inspection — see
|
||||
`extract_api.py`'s `identity_key()` docstring for the full history (a naive params-only key silently
|
||||
collided on overloads differing only by constness/SFINAE; libclang's USR fixed that but encoded the
|
||||
*enclosing class template's own arity*, so a single backward-compatible template-parameter addition
|
||||
made ~228 of 330 `basic_json` entries look "changed" between two real releases with zero actual
|
||||
breaking changes among them).
|
||||
|
||||
- An identity present only in the **new** snapshot → **feature** (addition).
|
||||
- An identity present only in the **old** snapshot → **breaking** (removal).
|
||||
- The same `(scope, name)` with one identity removed and a different one added → reported as a
|
||||
**changed overload**, classified breaking by default. No automatic overload-compatibility reasoning
|
||||
is attempted — whether a signature change is source-compatible is a judgment call for a human
|
||||
reviewer, not a sound problem for a CI tool to solve unsupervised.
|
||||
|
||||
## Stable per-release API history
|
||||
|
||||
`tools/api_checker/history/<tag>.json` holds one immutable, committed API-surface record per
|
||||
released `v3.*` tag (captured via `snapshot_release.py`; see `tools/api_checker/README.md` and
|
||||
`tools/api_checker/history/README.md`). `diff_api.py` reads from here automatically when a ref
|
||||
matches a stored file, instead of live-extracting via `git archive` every time.
|
||||
|
||||
Every surface file (the live `api_surface.json` and every `history/*.json` record) carries a
|
||||
`format_version` integer. **Bump it whenever a change to the schema, or to the identity-computing
|
||||
algorithm (`get_signature_text()`/`get_identity_name()`/`identity_key()` in `extract_api.py`), could
|
||||
alter the `signature` or `identity_name` text for otherwise-unchanged source.** `diff_api.py` refuses
|
||||
by default to compare two surfaces with different `format_version` values — this is a direct,
|
||||
mechanical safeguard against the exact class of bug that motivated the current identity scheme (see
|
||||
above): a silent algorithm change corrupting every historical comparison with no way to detect it.
|
||||
An explicit `--allow-format-mismatch` flag exists for a deliberate, informed comparison anyway.
|
||||
|
||||
Practical implication for anyone changing `extract_api.py`'s identity logic: bump
|
||||
`SURFACE_FORMAT_VERSION`, and treat every already-committed `history/*.json` file as needing a
|
||||
`--force` regeneration (reviewed, not blind) before it can be meaningfully compared against surfaces
|
||||
produced by the new algorithm version.
|
||||
|
||||
## Stability guarantees
|
||||
|
||||
This tooling makes the project's existing commitments *mechanically checkable* — it does not introduce a
|
||||
new promise:
|
||||
|
||||
- `ChangeLog.md` states the project "adheres to [Semantic Versioning](http://semver.org/)."
|
||||
- [docs/mkdocs/docs/home/releases.md](../../docs/mkdocs/docs/home/releases.md) marks every 3.x release "All
|
||||
changes are backward-compatible" (except 3.0.0 itself, a major bump with a migration guide).
|
||||
- `tests/abi/` provides a complementary, narrower guarantee: ABI/link compatibility *within one ABI tag*.
|
||||
That is a binary-compatibility concern; this tooling's concern is source/API-level — a symbol can be
|
||||
ABI-stable and still be a source-breaking change (e.g. a removed overload), or vice versa.
|
||||
|
||||
## Known limitations
|
||||
|
||||
- **Macros have no C++ access-specifier concept**, so the public/private test that works for classes
|
||||
doesn't transfer. Only a minority of documented macro `#define`s have an attached `@sa`-style comment
|
||||
(the `#ifndef X / #define X value #endif` idiom has no natural comment-attachment point), and internal
|
||||
helper macros live in the same files as public configuration macros, so no path-based exclusion works
|
||||
either. `check_macros.py` therefore only checks one direction: that every documented macro still has a
|
||||
matching `#define` somewhere under `include/nlohmann/` (catches stale/renamed doc pages). It does
|
||||
**not** attempt to detect undocumented macros — no reliable signal exists for that direction with the
|
||||
current codebase conventions, and this tool doesn't pretend otherwise.
|
||||
- **`diff_api.py` does not track exception specifications or template-parameter-only changes.** A
|
||||
function whose `noexcept` status changes, or whose template parameter list changes without altering
|
||||
its externally-visible identity, will not be flagged.
|
||||
- **Known API-hygiene gap, surfaced by this tooling rather than fixed**:
|
||||
`basic_json::insert_iterator` (a `public` member per C++ access rules) is a helper used internally by
|
||||
`insert()`; its own source comment calls it "Helper for insertion of an iterator." It has no
|
||||
documentation page and is deliberately left undocumented rather than either speculatively documented or
|
||||
silently exempted — this is exactly the class of undocumented-and-probably-shouldn't-be-public symbol
|
||||
this tooling exists to surface, per the motivating discussion. A future PR may reclassify it as private
|
||||
as a (breaking, ABI-relevant) cleanup; that is out of scope here.

# API Checker Tools
|
||||
|
||||
Tooling to extract, validate, and track changes to the public API surface of nlohmann/json.
|
||||
|
||||
## Overview
|
||||
|
||||
These tools use libclang AST parsing to programmatically derive "the public API" from C++ semantics
|
||||
(class templates, access specifiers, namespace scoping) — independently of documentation status. The
|
||||
extracted surface is the source of truth for what is considered "public API." On top of this, the tools
|
||||
verify that every public entity carries a documentation link and detect API changes between releases.
|
||||
A per-release historical record lives in [`history/`](history/README.md), one file per tagged `v3.*`
|
||||
release, so past API changes can be derived without re-running libclang against old git refs.
|
||||
|
||||
See [POLICY.md](POLICY.md) for the full definition of what counts as public API, what's excluded, how
|
||||
breaking vs. feature changes are classified, and known limitations.
|
||||
|
||||
## Installation
|
||||
|
||||
Install dependencies:
|
||||
|
||||
```bash
|
||||
pip install -r tools/api_checker/requirements.txt
|
||||
```
|
||||
|
||||
Requires:
|
||||
- Python 3.7+
|
||||
- libclang 18.1.1 (installed via pip)
|
||||
- clang++ or clang (system package, for include-path discovery only — does not need to
|
||||
version-match the pinned libclang wheel)
|
||||
|
||||
## Tools
|
||||
|
||||
### extract_api.py
|
||||
|
||||
Extract the public API surface by parsing C++ AST using libclang. Produces two different outputs for
|
||||
two different consumers — see "Two outputs, one extraction pass" below for why.
|
||||
|
||||
**Usage:**
|
||||
```bash
|
||||
python3 tools/api_checker/extract_api.py \
|
||||
--header include/nlohmann/json.hpp \
|
||||
--include include \
|
||||
--output api_snapshot.json \
|
||||
--surface-output api_surface.json
|
||||
```
|
||||
|
||||
**Options:**
|
||||
- `--header PATH` — Header file to analyze (default: `include/nlohmann/json.hpp`)
|
||||
- `--include PATH` — Include directory for parsing (default: `include`)
|
||||
- `--output PATH` — Full snapshot output (location + doc status; default: `api_snapshot.json`)
|
||||
- `--surface-output PATH` — Minimal surface output (identity only; omit to skip)
|
||||
- `--extra-isystem PATH` — Extra `-isystem` include path (repeatable), in case system-include
|
||||
discovery via `clang++ -E -v` ever fails on a given runner image
|
||||
- `--self-test` — Run self-tests and exit (validates ABI-tag stripping)
|
||||
|
||||
**How it works:**
|
||||
Parses the header file using libclang with `PARSE_DETAILED_PROCESSING_RECORD`, discovers system
|
||||
includes via `clang++ -E -x c++ -v /dev/null`, and walks the AST:
|
||||
|
||||
1. For each of the 6 public class templates (`basic_json`, `adl_serializer`, `byte_container_with_subtype`,
|
||||
`json_pointer`, `json_sax`, `ordered_map`): locate the `CLASS_TEMPLATE` cursor with `is_definition() == True`
|
||||
— never a `CLASS_DECL` implicit instantiation, which silently drops SFINAE-guarded overloads
|
||||
2. Extract public members: `CXX_METHOD`, `CONSTRUCTOR`, `DESTRUCTOR`, `CONVERSION_FUNCTION`, `FUNCTION_TEMPLATE`
|
||||
(callable tier — strict `@sa` requirement), and `TYPE_ALIAS_DECL` (type tier — with STL-container exemptions)
|
||||
3. Extract free functions in `nlohmann::` namespace (excluding `detail::` and `std::`)
|
||||
4. Normalize away ABI inline-namespace (regex `::json_abi[a-z_]*_v\d+_\d+_\d+` → `::`)
|
||||
5. Use overload-disambiguating identity keys built from raw source-text signature capture,
|
||||
ABI-tag-stripped — see "Identity keys" below
|
||||
|
||||
**Two outputs, one extraction pass:**
|
||||
- `--output` (full snapshot): each entry carries `location` (file:line) and documentation status
|
||||
(`doc_url`, `has_sa`). Consumed by `check_docs.py`. **Not meant to be committed** — `location` shifts
|
||||
on any unrelated code edit and `doc_url` changes when doc pages move, so a diff of this file mixes real
|
||||
API changes with pure noise.
|
||||
- `--surface-output` (minimal surface): each entry has only `scope`, `kind`, `name`, `identity_name`,
|
||||
`tier`, `signature`, and `pretty_signature` — nothing that can change without the API itself changing.
|
||||
**This is the file that gets committed** (`tools/api_checker/api_surface.json` for the current
|
||||
working tree, `tools/api_checker/history/<tag>.json` per released tag) and diffed by `diff_api.py`.
|
||||
|
||||
**Identity keys — three approaches were tried and rejected before arriving at the current one:**
|
||||
1. `{scope, name, kind, params}` from `cursor.get_arguments()`: silently collided for any overload set
|
||||
differentiated only by constness, ref-qualifiers, or SFINAE constraints rather than parameter types —
|
||||
confirmed empirically: `basic_json`'s two zero-argument `get()` overloads (one `const`, one not) both
|
||||
produced `params=[]` and silently overwrote each other. A full scan found **59 such silent overwrites
|
||||
across 27 colliding names**.
|
||||
2. libclang's USR: correctly disambiguates every overload (it encodes the full mangled signature) — but
|
||||
*also* encodes the enclosing class template's own arity into every member's USR. Confirmed
|
||||
empirically against real release tags: `basic_json` gaining one new defaulted template parameter
|
||||
between v3.11.2 and v3.11.3 (a backward-compatible change) changed literally every member's USR,
|
||||
which made `diff_api.py` report **228 of 330 entries as "changed"** for a release with zero real
|
||||
breaking changes among them.
|
||||
3. **Current approach**: raw source-text signature capture — `identity = (scope, identity_name, kind,
|
||||
signature)`, where `signature` is the declaration's own text (return type, name, parameter list,
|
||||
trailing cv/ref/noexcept qualifiers; comments and constructors' member-initializer-lists stripped;
|
||||
stops before the function body) read directly via the cursor's byte-offset extent. This is what's
|
||||
actually written in source — declared names like `ValueType`, never a resolved
|
||||
`basic_json<T0,...,T10>` — so it's immune to the class-arity problem above. Verified by manually
|
||||
cross-referencing every "added"/"removed"/"changed" entry in three real release-to-release diffs
|
||||
(v3.11.2→v3.11.3, v3.11.3→v3.12.0, v3.12.0→HEAD) against the actual `git diff` of the source — every
|
||||
one confirmed genuine. Full details, including several further edge-case fixes found the same way
|
||||
(a libclang tokenizer gap, comment-stripping, constructor-name arity-poisoning), are in
|
||||
`extract_api.py`'s `identity_key()`/`get_signature_text()` docstrings.
|
||||
|
||||
**Output (full snapshot, from `--output`):**
|
||||
```json
|
||||
{
|
||||
"meta": {
|
||||
"extracted_from": "include/nlohmann/json.hpp"
|
||||
},
|
||||
"public_api": {
|
||||
"<opaque internal key, not meant to be read>": {
|
||||
"scope": "nlohmann::basic_json",
|
||||
"name": "parse",
|
||||
"identity_name": "parse",
|
||||
"kind": "CXX_METHOD",
|
||||
"tier": "callable",
|
||||
"signature": "static basic_json parse ( InputType && i , ... )",
|
||||
"location": "include/nlohmann/json.hpp:4104",
|
||||
"doc_url": "https://json.nlohmann.me/api/basic_json/parse/",
|
||||
"has_sa": true,
|
||||
"pretty_signature": "nlohmann::basic_json::parse"
|
||||
}
|
||||
},
|
||||
"documented_non_public": []
|
||||
}
|
||||
```
|
||||
|
||||
`documented_non_public` lists entities **not** part of the public surface (private/protected members of
|
||||
the six tracked classes) that surprisingly carry an `@sa` URL into the documentation site
|
||||
(`https://json.nlohmann.me/`) — a genuine documentation leak. `@sa` links to anything else, such as GitHub
|
||||
issues, are ignored. It does not list public entries that merely lack `@sa`; that's `check_docs.py`'s job.
|
||||
|
||||
**Output (surface, from `--surface-output`):**
|
||||
```json
|
||||
{
|
||||
"format_version": 1,
|
||||
"meta": {
|
||||
"extracted_from": "include/nlohmann/json.hpp"
|
||||
},
|
||||
"public_api": [
|
||||
{
|
||||
"scope": "nlohmann::basic_json",
|
||||
"kind": "CXX_METHOD",
|
||||
"name": "parse",
|
||||
"identity_name": "parse",
|
||||
"tier": "callable",
|
||||
"signature": "static basic_json parse ( InputType && i , parser_callback_t cb = nullptr , const bool allow_exceptions = true , const bool ignore_comments = false )",
|
||||
"pretty_signature": "nlohmann::basic_json::parse"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
A flat, sorted list of self-describing records — `signature`/`identity_name` are the same values
|
||||
`identity_key()` joins into one opaque internal string, exposed here as explicit fields so the file is
|
||||
readable and diffable by inspection, not just by tooling. `identity_name` differs from `name` only for
|
||||
constructors/destructors (a canonical `"(constructor)"`/`"(destructor)"` placeholder — see
|
||||
`get_identity_name()`'s docstring for why `cursor.spelling` isn't used directly there).
|
||||
|
||||
`format_version` guards against a future change to this schema or to the identity-computing algorithm
|
||||
silently corrupting a comparison against an older stored surface — bump it whenever such a change could
|
||||
alter `signature`/`identity_name` text for otherwise-unchanged source (see `diff_api.py`).
|
||||
|
||||
### check_docs.py
|
||||
|
||||
Verify that all public API entries have valid documentation links and that no non-public entities
|
||||
carry `@sa` comments.
|
||||
|
||||
**Usage:**
|
||||
```bash
|
||||
python3 tools/api_checker/check_docs.py --snapshot api_snapshot.json
|
||||
```
|
||||
|
||||
**Options:**
|
||||
- `--snapshot PATH` — Full API snapshot JSON file from `extract_api.py --output` (default: `api_snapshot.json`)
|
||||
|
||||
**How it works:**
|
||||
Two-pass validation over the extracted snapshot:
|
||||
|
||||
1. For every `public_api` entry (callable tier, and type tier minus STL exemptions): flag if missing `@sa`,
|
||||
flag if `@sa` URL doesn't resolve to an existing documentation file (following `docs/mkdocs/mkdocs.yml`'s
|
||||
`redirect_maps` when a page has moved, and trying the class-overview conventions used by different
|
||||
classes — flat `<class>.md`, nested `<class>/<class>.md`, nested `<class>/index.md`)
|
||||
2. For every `documented_non_public` entry: flag as unexpected `@sa` on a non-public entity
|
||||
|
||||
**Output:**
|
||||
Prints warnings for each issue, categorized by rule:
|
||||
- `docs/missing_sa_comment` — public API without `@sa` documentation link
|
||||
- `docs/missing_doc_file` — `@sa` URL points to non-existent `.md` file
|
||||
- `docs/invalid_sa_url` — malformed `@sa` URL
|
||||
- `docs/sa_on_non_public` — unexpected `@sa` on a non-public entity
|
||||
|
||||
Exits with status 0 if all checks pass, 1 if issues found.
|
||||
|
||||
### diff_api.py
|
||||
|
||||
Compare the public API surface between two refs and classify changes as feature (added) or
|
||||
breaking (removed / changed overload).
|
||||
|
||||
**Usage:**
|
||||
```bash
|
||||
python3 tools/api_checker/diff_api.py --old v3.12.0 --new HEAD
|
||||
python3 tools/api_checker/diff_api.py --old v3.11.2 --new v3.11.3 # both resolved from history/
|
||||
python3 tools/api_checker/diff_api.py --old v3.12.0 --new HEAD --fail-on-breaking
|
||||
python3 tools/api_checker/diff_api.py --old-file a.json --new-file b.json # compare two files directly
|
||||
```
|
||||
|
||||
**Options:**
|
||||
- `--old REF` / `--new REF` — Refs to compare (tags, branches, commits). `--new` defaults to `HEAD`.
|
||||
Each is resolved by checking `tools/api_checker/history/<ref>.json` first (fast — no libclang or
|
||||
git-archive needed), falling back to live extraction if no matching file exists there.
|
||||
- `--old-file PATH` / `--new-file PATH` — Load an arbitrary surface JSON file directly, bypassing
|
||||
both git and `tools/api_checker/history/`. Mutually exclusive with `--old`/`--new` respectively.
|
||||
- `--no-history` — Force live extraction even when a matching `tools/api_checker/history/<ref>.json`
|
||||
exists. Useful to check that a stored record is still faithful to a fresh run of the current tool.
|
||||
- `--allow-format-mismatch` — Proceed even if the two surfaces have different `format_version`
|
||||
(otherwise `diff_api.py` refuses — see below).
|
||||
- `--header PATH` / `--include PATH` — For live extraction only (default:
|
||||
`include/nlohmann/json.hpp` / `include`)
|
||||
- `--fail-on-breaking` — Exit with status 1 if breaking changes are detected
|
||||
|
||||
**How it works:**
|
||||
For a ref not found in `tools/api_checker/history/`, checks out the **full `include/` tree** at
|
||||
that ref into a temp directory via `git archive` (a single-file checkout of `json.hpp` is not
|
||||
enough — it `#include`s dozens of other headers that must exist at the same ref), then runs the
|
||||
*current* `extract_api.py --surface-output` against it. Diffs the two surfaces by identity
|
||||
(`scope`, `identity_name`, `kind`, `signature`):
|
||||
- Identity only in the new surface → **feature**.
|
||||
- Identity only in the old surface → **breaking** (removed).
|
||||
- Same `(scope, name)` with a removed identity and an added identity → grouped as a **changed
|
||||
overload**, breaking by default. No automatic overload-compatibility reasoning is attempted — a
|
||||
human judges whether the change is actually source-compatible.
|
||||
|
||||
Before diffing, the two surfaces' `format_version` fields are compared; a mismatch aborts with an
|
||||
error (override with `--allow-format-mismatch`) rather than silently producing an unsound diff — see
|
||||
`extract_api.py`'s `SURFACE_FORMAT_VERSION` docstring for the incident that motivated this guard.
|
||||
|
||||
ABI-tag stripping is inherited automatically since both extractions go through the same
|
||||
`extract_api.py`.
|
||||
|
||||
**Use case:** Run before cutting a release to verify the changelog correctly categorizes changes as
|
||||
breaking vs. features.
|
||||
|
||||
### snapshot_release.py
|
||||
|
||||
Capture an immutable, per-release API surface record into `tools/api_checker/history/<tag>.json`.
|
||||
This is what makes `diff_api.py` fast for released tags — see "How it works" above.
|
||||
|
||||
**Usage:**
|
||||
```bash
|
||||
python3 tools/api_checker/snapshot_release.py --ref v3.12.0
|
||||
python3 tools/api_checker/snapshot_release.py --ref v3.11.0 --ref v3.12.0 # repeatable
|
||||
python3 tools/api_checker/snapshot_release.py --all-tags # every v3.* tag
|
||||
python3 tools/api_checker/snapshot_release.py --ref v3.12.0 --force # overwrite an existing record
|
||||
```
|
||||
|
||||
**Options:**
|
||||
- `--ref REF` — Git tag to snapshot; repeatable
|
||||
- `--all-tags` — Snapshot every `v3.*` tag (existing files are skipped unless `--force`)
|
||||
- `--output-dir PATH` — Where to write (default: `tools/api_checker/history/`)
|
||||
- `--force` — Overwrite an existing history file. History files are immutable by convention —
|
||||
only pass this for a deliberate, reviewed regeneration; review the resulting diff before
|
||||
committing
|
||||
- `--header PATH` / `--include PATH` — Same as `diff_api.py`'s live-extraction options
|
||||
|
||||
**How it works:** Reuses `diff_api.py`'s `extract_surface_for_ref()` for the git-archive-and-extract
|
||||
work, then adds `generated_at`/`generator` provenance and writes the result to
|
||||
`tools/api_checker/history/<ref>.json`. Given multiple refs (or `--all-tags`), does **not** abort
|
||||
the batch on one failing ref — collects failures and prints a summary at the end, so one
|
||||
unparseable old tag doesn't block backfilling the releases that do work. See
|
||||
`tools/api_checker/history/README.md` for the currently-known gaps (pre-restructuring tags that
|
||||
predate the `include/nlohmann/` layout entirely).
|
||||
|
||||
**Not CI-automated** — this is a manual step in the release checklist (see below), by design.
|
||||
|
||||
### check_macros.py
|
||||
|
||||
Advisory-only cross-check between documented macros and their `#define`/reference sites. **Never blocks
|
||||
CI**, regardless of findings.
|
||||
|
||||
**Usage:**
|
||||
```bash
|
||||
python3 tools/api_checker/check_macros.py
|
||||
```
|
||||
|
||||
**Options:**
|
||||
- `--macros-dir PATH` — Directory of macro doc pages (default: `docs/mkdocs/docs/api/macros`)
|
||||
- `--include-dir PATH` — Directory to search for `#define`/reference sites (default: `include/nlohmann`)
|
||||
|
||||
**How it works:**
|
||||
For each `.md` page under `docs/mkdocs/docs/api/macros/` (excluding `index.md`), extracts the macro
|
||||
name(s) from the H1 heading — handling both plain single-macro headings and multi-line HTML headings
|
||||
that list a family of related macros (e.g. the `NLOHMANN_DEFINE_DERIVED_TYPE_*` family) — then checks
|
||||
whether each name is defined **or referenced** (`#define`, `#ifdef`, `#ifndef`, `defined(...)`) anywhere
|
||||
under `include/nlohmann/`. Referenced-but-not-defined is deliberately accepted: macros like
|
||||
`JSON_NOEXCEPTION` or `JSON_THROW_USER` are user-supplied overrides that the library only checks for,
|
||||
never defines itself.
|
||||
|
||||
Only checks the documented-macro-still-exists direction (catches stale/renamed doc pages). Does **not**
|
||||
check the converse (undocumented macros) — see [POLICY.md](POLICY.md)'s "Known limitations" for why.
|
||||
|
||||
## Continuous Integration
|
||||
|
||||
A GitHub Actions workflow (`.github/workflows/check_api_docs.yml`) runs on every pull request:
|
||||
|
||||
1. Installs `clang` (system package, for include discovery) and Python dependencies
|
||||
2. Runs `extract_api.py`, regenerating both the ephemeral full snapshot and the tracked
|
||||
`tools/api_checker/api_surface.json`
|
||||
3. Runs `check_docs.py` — **Phase 1: advisory** (`continue-on-error: true`), surfacing the doc backlog
|
||||
without failing the job while it's burned down. Will flip to blocking once the backlog is cleared.
|
||||
4. Runs `check_macros.py` — always advisory
|
||||
5. Diffs `tools/api_checker/api_surface.json` against the regenerated copy — **blocking from the start**
|
||||
(unlike the doc-backlog check, this is purely mechanical regeneration with no backlog to phase in,
|
||||
matching the precedent set by `check_amalgamation.yml`). Uploads a patch artifact if it differs, so
|
||||
contributors can `git apply` it instead of installing libclang locally.
|
||||
|
||||
## Workflow: Adding New Public API
|
||||
|
||||
1. Add the new public method/function to the header
|
||||
2. Add a `/// @sa https://json.nlohmann.me/api/<class>/<member>/` comment above it
|
||||
3. Create the corresponding documentation page at `docs/mkdocs/docs/api/<class>/<member>.md` and a
|
||||
`mkdocs.yml` nav entry
|
||||
4. Regenerate and commit the tracked surface file:
|
||||
```bash
|
||||
python3 tools/api_checker/extract_api.py --surface-output tools/api_checker/api_surface.json
|
||||
git add tools/api_checker/api_surface.json
|
||||
```
|
||||
5. Push your PR — CI verifies both the doc link and that the surface file is up to date
|
||||
|
||||
## Workflow: Release Checklist
|
||||
|
||||
Before cutting a release:
|
||||
|
||||
```bash
|
||||
# Diff current API against the previous release
|
||||
python3 tools/api_checker/diff_api.py --old v3.12.0 --new HEAD
|
||||
|
||||
# Review the output to verify the changelog correctly categorizes breaking vs. feature changes
|
||||
```
|
||||
|
||||
After tagging the release:
|
||||
|
||||
```bash
|
||||
# Capture and commit the new tag's API surface, so future diffs against it hit the fast,
|
||||
# stored-file path instead of live-extracting every time. A manual step, not CI-automated.
|
||||
python3 tools/api_checker/snapshot_release.py --ref v3.13.0
|
||||
git add tools/api_checker/history/v3.13.0.json
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
**libclang not found:**
|
||||
```
|
||||
Error: Could not locate libclang library
|
||||
```
|
||||
→ Ensure libclang is installed: `python3 -m pip install libclang==18.1.1`
|
||||
|
||||
**Parse errors in header:**
|
||||
```
|
||||
Parse errors encountered:
|
||||
... list of diagnostics ...
|
||||
```
|
||||
→ Check that system includes can be discovered. Run `clang++ -E -x c++ -v /dev/null` and verify
|
||||
the output includes a section titled `#include <...> search starts here:` with system paths.
|
||||
If include discovery fails, use `--extra-isystem PATH` to provide additional paths.
|
||||
|
||||
**No API entries extracted (or very few):**
|
||||
- Check that the header file exists and is valid C++: `ls -la include/nlohmann/json.hpp`
|
||||
- Verify that no parse errors occur above
|
||||
- Confirm that you're targeting a `CLASS_TEMPLATE` definition, not an implicit instantiation
|
||||
(the tool logs `Found N public API entries` — a zero or very small count suggests the wrong cursor kind)
|
||||
|
||||
**Doc link returns 404:**
|
||||
- Verify the file exists at the expected path: `docs/mkdocs/docs/api/<class>/<member>.md`
|
||||
- Check for URL encoding issues (e.g., `operator[]` → `operator%5B%5D`)
|
||||
- Verify the URL structure in the `@sa` comment: should be `https://json.nlohmann.me/api/<path>/`
|
||||
- Check `docs/mkdocs/mkdocs.yml`'s `redirect_maps` if the page has moved
|
||||
|
||||
**`tools/api_checker/api_surface.json` is out of date in CI:**
|
||||
→ Regenerate and commit it: `python3 tools/api_checker/extract_api.py --surface-output tools/api_checker/api_surface.json`
|
||||
|
||||
**`diff_api.py` refuses with "format_version mismatch":**
|
||||
→ One side is a stored surface (live `api_surface.json` or a `tools/api_checker/history/*.json`
|
||||
file) captured with an older/newer version of `extract_api.py`'s identity-computing algorithm than
|
||||
the other side. Comparing them directly could produce an unsound diff (this is exactly the failure
|
||||
mode that motivated adding the check — see `extract_api.py`'s `SURFACE_FORMAT_VERSION` docstring).
|
||||
Either regenerate the older side with the current tool, or pass `--allow-format-mismatch` if you
|
||||
understand the risk and want to proceed anyway.
