What's new

0.10.3 (preview): the first listing on the Marketplace

Everything since the first 0.10.2 build:

• The debugger: a real step debugger in the shared session. Breakpoints in the margin (conditions, hit counts, log points), Stop at Line (also inside a function), next, step in, step out, continue, Run to Cursor, stop on a warning, Break on Value Change, the call stack and the variables of each frame (a data frame opens to its columns and labels), the Debug Console in the frame. A stop of dsr run --stop-at or of pry() waits, and dsr pry next | step | finish | continue | quit goes on from it. Works in VS Code and Positron.
• Problems and the Suspicious Log: a run's errors and warnings at their file and line; the messages that are often bugs (text that became NA, a join that adds rows, a type change, an empty column), each with why and the fix.
• Coverage: how often each line ran, and the lines that never ran.
• The data viewer: a filter under each column (>13, 1-5, a,b, !a, A*), the value picker, cell filters, the filters as chips, sort by several columns, find a column by its label, raw or formatted values, Keys, a row as a record, and the view as dplyr and base R code; 150,000 rows stay quick.
• Autocomplete that knows the session: functions and their arguments, packages, data frames and their columns with labels (also in a pipe and in admiral's exprs()); hover, signature help, go to definition; clinical snippets, each run on pharmaverse data by the tests.
• Format Document with styler, written only with the proof that only the layout changed.
• The call form: a function's arguments as a form, then Trace or Debug the call.
• dsr, the command line for you and AI agents: --json on every tool, documented exit codes, --timeout with wait and stop, cut long output with more, dsr sessions and --root, dsr doctor with a fix for every failed check, dsr guide; the session's tools survive a program's rm(list = ls()).
• MCP server: 46 typed tools, the twins of the dsr tools; a cancel reaches a running call.
• Lint: with lintr installed, no more false alarms for functions defined in another file of the same lint, and no second message in other words for a line that already has one.
• The manual (docs/manual): a tutorial per feature on one example study, run by the tests; which debugger when; questions; privacy.
• Get started: a walkthrough in the editor's Welcome page (open a folder, start the session, run, stop at a line, look at the data, optional agent tools).
• Installer scripts (install/install.sh; install.ps1, not tested on Windows).

0.10.2 (preview)

The first build, given as a file: the shared R session with the SAS-style log (a NOTE per data frame), pry, trace, the pipe debugger, the data viewer, lint, batch runs, the dsr command and its MCP server, the clinical add-on (subject, spec, cdisc, adam check, numbers, app check, gate, New Dashboard Project), and the Agent panel (Claude Code or a local model through Ollama).
