The service was offered under MIT or Apache-2.0. It is now under the
GNU General Public License, version 3 or later, and that alone: the two
other licence files are removed and the manifest names one licence.
`apsis-rs` is still MIT or Apache-2.0; both permit redistribution
inside a GPL work, so the two may be distributed together under these
terms.
Every document now has a Chinese form. The concept set already had one
for each of its thirty-one documents; the README and the design notes
did not, and both now do.
The design notes carried two sections under the same heading and two
under another, so the second copy of each was unreachable from the
outline. They are merged into one section apiece, keeping every distinct
decision and dropping the two lead-ins that said the same thing twice.
A bracketed group was never given its power, so `(1 - e^2)^2` and every
line of that shape were shown as source. An operator written with its
spacing was emitted as bare text, and a browser drops bare text inside a
row, which lost the sign of a difference: `1 - e^2` came out as `1e^2`.
A parenthesis holding words was read as a note about the equation rather
than as part of it, so `(cos theta)` and `(m * g)` broke the lines that
held them; the parser now decides, and the column a note is set in is
what marks it. A vertical bar ended an absolute value only from the
outside, so `| f'(x) | * | x| / | f(x) |` did not read.
A grid track of `minmax(28rem, 1fr)` is wider than a phone, so the
interface page of a crate scrolled sideways. The track now takes
`min(28rem, 100%)` and shrinks to the width it has.
The equations of the documents went from seventy being set as formulas
to ninety-six. What is left is pseudocode and matrices, which are source
rather than formulas.
A translation was filed under the item name alone. The name is not
unique: `new` is used by fifty-nine crates and `kind` by fifteen, and
they do not all mean the same thing by it, so a name-only translation
could be shown against the wrong documentation. A translation is now
looked up by `crate::name` first, then by `Type::name` for two items
of one crate that share a name, and only then by the bare name.
The facade crate sits directly in `crates` and re-exports every layer.
It defines nothing of its own, so listing it repeated every item of the
layers under a second name. The generator skips it and the catalog
carries forty crates.
The first batch of Chinese translations is in, covering the foundation,
time, coordinate, geodesy, frames, Kepler, SGP4 and linear algebra
crates.
The documents write their formulas as plain text in a fenced block,
`delta_v = v_e * ln (m_0 / m_f)`, which was shown as source. They were
written before the dollar form existed. A plain block holding equations
is now read as a formula: identifiers with subscripts and powers, roots,
functions, quotients, a group raised to a power, and a note set beside
the equation. A block that is not an equation, such as a matrix or a
worked example in prose, stays as it was written.
The interface catalog named fifteen crates in the generator, which was
written when only the foundation, physics and orbit crates existed. The
workspace has since grown to forty-one, and every network, radio and
operations crate was missing from the documentation without anything
saying so. The crates now come from the workspace manifest, so a crate
cannot be left out by omission again. The count went from 424 items to
1202, and the index now shows all seven layers.
A crate with no layer is the facade, which re-exports every layer. It is
left without one rather than filed under the foundation, and it is left
out of the crate structure diagram, where it would belong to no layer.
A page change did not move the scroll position, so following a link from
the bottom of a long document landed in the middle of the next one. The
scroll now follows the path rather than the fragment, so a filter applied
to the page a reader is on leaves them where they are. The browser fires
`popstate` for a fragment navigation as well as for a traversal, so
there is no event that means "this was a traversal" on its own, and going
back starts at the top rather than where the reader left.
The interface index listed fifteen crates in one grid. It is now grouped
by layer, with the title and order the concept documentation already
declares, and a card shows the opening sentence of the crate summary
rather than the whole of it, which is what made the cards four hundred
pixels tall.
A tool result showed its column headings, scalar labels and notes in the
reader's language, but left the table body in English. Text cells are now
looked up as well. Units are written with a power, and are set as one.
A tool description is Markdown, so it is now rendered as such, as are the
parameter help and the notes. A formula written between dollar signs is
set the same way in both places.
The graph took over three seconds to draw. The force layout ran four
hundred and twenty steps of repulsion between every pair of nodes, which
is quadratic in the node count and was doing that work through a reactive
proxy inside an effect that read the state it wrote, so it rescheduled
itself on every run. The repulsion now runs on a grid over neighbouring
cells, and the effect no longer tracks its own writes.
The physics layer covered two unrelated subjects, so it is presented as
two. Formulas are written between dollar signs and translated to MathML,
which the browser sets itself, so no script has to run. The palette is
now two sets of the same variables with a toggle between them, and below
a thousand pixels the sidebar is a drawer over the page.
