Extends the checker to the module level `//!` docs, the tests, the
examples, and the non-Rust prose comments in the workflow, the manifests
and the shell and Python scripts.
The Delaunay and planetary arguments, the precession, nutation, polar
motion and Earth rotation angles, and the TEME and terrestrial matrices.
This completes the bilingual sweep: every comment block in the workspace
now carries its Chinese counterpart.
The event queue and identifiers, the output records and trace, the scenario
build and parse, and the run facade, including the plain comments inside
the functions.
The error modules across the remaining crates share a shape, so one table
covers them all. Also the inter-satellite link geometry and the mesh
connectivity analysis, including the Menger and Kosaraju notes.
A translation table for the sentences that recur across the error types
and the simple accessors let the same wording be applied everywhere at
once, which both keeps the Chinese consistent and covers a hundred and
twenty-nine sites in a single pass. Routing, topology, access and the radio
frequency crates are now part of the sweep.
The layer is complete at three hundred and sixty two blocks across the
resource, task, schedule, conflict and scheduler crates, including the
swept search and the improvement pass.
Seventy-five comment blocks across the error kinds, the resource model
and the window algebra. The English is unchanged and the Chinese follows
under a blank doc line, as the glossary sets out.
Three measurements, each answering a different question: what one call
costs, how the cost grows with size, and what the other cores save. The
method states the three rules the tools follow, no warm-up, best of several
runs, and cost per unit rather than an absolute figure, so a reader can
reproduce and judge.
The findings are that the numerical kernels are linear and parallelise
well, a day over two thousand satellites costs 0.7 seconds on one core and
81 milliseconds on sixteen, and that interpolation is about ten times
cheaper than propagation. Two combined operations are limited by their
algorithm: greedy planning is quadratically serial, and the duplicate
check on edge insertion squares that quadratic, so threading helps neither.
Eight threads is recommended, since efficiency falls to about half at
sixteen.
Applies the glossary across apsis-math, apsis-time, apsis-leap,
apsis-coord, apsis-geodesy and the five orbit crates that were already
implemented, plus apsis-ephemeris, apsis-maneuver and apsis-orbit. Five
hundred and seven comment blocks now carry the English paragraph and the
Chinese one.
The checker learned to skip a comment that is only a formula, since a bare
symbol has no prose to translate and repeating it in Chinese would be noise.
The SGP4 cross-check still passes, so nothing in the numerical path moved.
Four of the five physics crates are done, 104 of 239 blocks in the layer.
The remaining one is apsis-frames, which holds the IAU 2000 Earth
orientation models and carries the largest number of formulas.
All 180 comment blocks across apsis-core, apsis-units and apsis-math now
carry both languages. The checker confirms no mangled bytes and no English
word left inside a Chinese sentence, two mistakes that occurred while
writing them and are now caught mechanically.
apsis-units and apsis-core are done, 86 of 180 comment blocks in the
layer. The checker in scripts/check-bilingual.py reports which blocks still
lack Chinese, and also catches the two mistakes that are easy to make while
adding a language: a mangled byte sequence, and an English word left inside
a Chinese sentence, which is what happened once in quantity.rs and is now
caught mechanically.
Translations keep terms that have a standard Chinese name in Chinese and
leave proper nouns, abbreviations and method names in English, as the
glossary sets out. The English text is never reworded.
The comment said the inclination was rounded to one decimal place, but
the format prints it at full precision, so 53.25 degrees came out intact
where the comment promised 53.2. The notation is an identifier, so
truncating it would lose information for nothing.
The first crate of the sweep, so the layout can be checked before the
remaining forty. English paragraph, empty doc line, then the Chinese, per
the glossary. Terms with a standard Chinese name use it directly, so
semi-major axis reads 半长轴 rather than carrying the English each time;
Walker, SGP4 and the frame abbreviations stay as they are.
Every comment block in the crate now has both languages, the Display
strings are untouched because translating them would change what a program
prints, and the three formulas the comments state were checked against the
code: the phase offset is 2 pi f / t, the plane spacing 2 pi / p, and the
anomaly spacing 2 pi / (t / p), all of which match.
The bilingual documentation convention needs a rule for terms, otherwise the
same word gets translated two ways in two files. The glossary separates the
terms that keep their English form, being proper names, abbreviations and
methods that exist only in English in the source literature, from the terms
that have a standard Chinese name and use it directly. It also fixes how a
formula is written, since a formula in a comment has to agree with the code
it describes.
Both languages are written, as the convention requires.
The search binary searches the sample list to interpolate between the two
samples that straddle a crossing, and a binary search over an unordered
list returns a wrong index instead of failing. Only the first and last
times were checked, so a sequence whose ends were in order but whose
middle was not refined each crossing against the wrong pair of positions
and reported a pass that never happened. On a circular ground track,
shuffling two samples changed the result from three passes to two and
still returned Ok.
The whole sequence is now checked, with a new UnorderedSamples error kind
that says which pair is out of order. The test covers the middle-of-
sequence case that the end check missed.
Two comments also described something other than what the code does, and
two Option-returning accessors did not say what makes them None:
- GravityModel::x2o3 is the constant 2/3, used as an exponent in the
mean motion and drag corrections, not 2 * xke^2 as its comment claimed;
the sgp4 reference implementation uses the same constant the same way.
- WalkerPattern::plane_spacing and phase_offset returned None without
saying so, which is the case a caller has to handle.
Both READMEs claimed twelve expect sites where there are thirteen, because
apsis-math/src/parallel.rs added one and the count was not carried over.
The notes were Chinese only, so a reader arriving from GitHub, which
renders README.md by default, met a wall. Each note now follows the
convention the wider ecosystem uses: English in X.md and Simplified
Chinese in X.zh.md, with a switch at the top of both, the way
zeromicro/go-zero and alist-org/alist present theirs.
The Chinese text moved to the .zh.md name rather than being rewritten, so
nothing was lost, and the English is a translation of the same content
rather than a summary of it.
Two figures in the notes had gone stale and are corrected while
translating: there are thirteen expect assertions rather than twelve,
because apsis-math/src/parallel.rs added one, and the table listed eight
of them rather than all. The layer note no longer quotes an edge count,
which changed as the code grew and was already out of date.
