* Add conditional expressions and table viewseunhhu2026-09-251-2/+27
| | | | | | | | | | | | | | | | | if c { a } else { b }, with else-if chains, is an expression anywhere a value goes. Only the chosen branch runs, every branch gives the same type, and nesting that would pass Pure's limit of 8 value-carrying joins is a compile error. view name = each row in list { column = value ... } declares a table with a row per item; columns read their row as an index of the list. An index now reads and writes its item's fields directly (at.title, at.done = 1), so 'position' cannot name a record field. examples/tasks.aup gains conditional views and a board table and still matches its reference model; a new check confirms the unchosen branch is never computed.
* Add records, lists and indiceseunhhu2026-09-251-2/+42
| | | | | | | | | | | | | | A record declares named number and text fields with defaults. A list of a record is runtime-owned state, and an index of a list always names one of its items: it follows its item across inserts and removes and stops at the ends. Items are read and changed by field (tasks[at].title), appended or inserted as record values whose missing fields take defaults, and removed by index. Using an index of another list is a compile error. examples/tasks.aup matches a Python reference model over 4,800 random steps, including events that fail on an empty list. Replacing it with a module whose record gained and reordered fields keeps every item.
* Document the text language as implementedeunhhu2026-09-251-1/+17
| | | | | | | Record v0b as complete: which text syntax exists, what is still missing (multi-line strings, formats, graphemes, words), the insertion rule for cursors, and how the text model and parity checks verify it.
* Compile messages and keyed documents to module v2eunhhu2026-09-251-1/+1
| | | | | | | | | | | | | | | | | | aup now emits Pure module v2 and adds keyed byte collections (state documents: bytes by key), message inputs by key with u32 and a trailing bytes field, on-message handlers, field access, name[key] reads and .bytes sizes, replace(a .. b, value), reply and require, all checked for number/bytes types with file:line:column diagnostics. The document editor and its size-bounded variant are rewritten in aup. make check runs them through pure-edit-module against pure-edit running the original editor.pure programs: 1,280 random show/edit/apply operations, including conflicts, limits, missing documents, budgets and invalid keys, produce byte-identical stdout, stderr and exit codes, and each CLI reads the other's store identically. v0a parity with the workbench engine, 33 diagnostics and generated/damaged programs still pass, also with a sanitizer-built compiler.
* Set the DSL direction and the text modeleunhhu2026-09-251-0/+70
aup declares connections and leaves storage, transactions and screen models to Pure. Interface vocabulary lives in Vega, an aup library, not in the language. text is one immutable UTF-8 type from a word to a 1 MiB document; positions are cursors bound to a value that stay on character boundaries and follow edits, lengths name their unit, and comparison is exact without silent normalization. Stages v0b-v0d and their acceptance tests are listed.
