Purpose

Resolves #2457

Goals

  • Requests run together share captured variables, so [Captures] in one request can be used by later ones.
  • Users can supply input variables from a file instead of hardcoding them.
  • hurl CLI options are configurable from settings.
  • All of the above is documented in the README.

Approach

  • Chaining — cells run together (Run All, or a multi-cell selection) are combined into one .hurl document and executed as a single hurl invocation, so hurl's own capture-to-variable semantics apply. Results are mapped back to each cell by line range (composeHurlDocumentWithBoundaries in hurl-parser + mapFileResultToCellOutcomes in hurl-runner), which keeps attribution correct even when a cell contains no request (e.g. a leading comment block) or more than one. A cell run on its own still runs in isolation; if it fails on an unset variable, the output hints to run cells together.
  • Variables — a shared hurl.vars under the resolved fileRoot, plus an optional per-file <name>.hurl.vars override, both passed straight to hurl's native --variables-file. No bespoke format or parser.
  • CLI options — new hurl-client.insecure, hurl-client.followRedirects and hurl-client.extraArgs settings, threaded through the existing HurlRunOptions/buildHurlArgs path.

Side effect: Run All is now roughly 2x faster, since it spawns one hurl process instead of one per cell.

UI Component Development

N/A — no new UI. Results continue to render as Markdown in the notebook cell output area.

  • Added reusable UI components to the ui-toolkit. Follow the intructions when adding the componenent.
  • Use ui-toolkit components wherever possible. Run npm run storybook from the root directory to view current components.
  • Matches with the native VSCode look and feel.

Manage Icons

N/A — no icons added.

  • Added Icons to the font-wso2-vscode. Follow the instructions.

User stories

Full list in #2457. In short: chain a login/token request into the requests that follow it, define base_url/api_key once in a variables file, toggle TLS verification and redirect following, and discover all of it from the README.

Release note

Hurl Client: requests run together now share captured variables (request chaining), input variables can be supplied from a hurl.vars file, and hurl CLI options (insecure, follow-redirects, extra arguments) are configurable.

Documentation

workspaces/hurl-client/hurl-client-extension/README.md — new "Chaining requests", "Variables" and "Settings" sections, with a runnable capture-then-reuse example.

Training

N/A

Certification

N/A — no impact on certification exams; this is a bug fix to an editor extension.

Marketing

N/A

Automation tests

  • Unit tests

    Added to the two shared packages that own the new logic: hurl-parser (document composition and cell boundaries) and hurl-runner (--variables-file/extraArgs argument construction, report-to-cell mapping including the lineless-entry and stopped-early cases). Suites pass: hurl-parser 28, hurl-runner 32.

  • Integration tests

    None. hurl-client-extension has no test harness (pre-existing), so the new logic was deliberately pushed down into the shared packages where it is unit-testable. End-to-end behaviour — chaining, variables file pickup, and each CLI flag — was verified manually against a real hurl 7.1.0 binary.

Security checks

  • Followed secure coding standards in http://wso2.com/technical-reports/wso2-secure-engineering-guidelines? yes
  • Ran FindSecurityBugs plugin and verified report? N/A — FindSecurityBugs targets Java; this change is TypeScript.
  • Confirmed that this PR doesn't commit any keys, passwords, tokens, usernames, or other secrets? yes. Note that variables files are plaintext by design (hurl's native format), so the README warns against committing real secrets. Extra arguments are passed to spawn as an argv array with shell: false, so they are not shell-interpreted.

Samples

N/A

Related PRs

N/A

Migrations (if applicable)

N/A — settings are additive and default to previous behaviour; existing .hurl files are unaffected.

Test environment

Node 22, VS Code 1.100+, hurl 7.1.0 (managed binary), macOS (arm64).

Learning

hurl already supports everything needed here natively — --variables-file for input variables, and capture propagation across entries within a single invocation. The gap was that the extension ran each cell as its own hurl process, which discards that state. The fix was to stop working around hurl and let it do the work, rather than reimplementing capture propagation in the extension.

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

The PR combines non-empty Hurl notebook cells into one run, maps results back to cells, adds variable-file and CLI argument support, improves per-cell output handling, updates extension settings and documentation, and renames the VS Code launch configuration.

Changes

Hurl notebook execution

Layer / File(s) Summary
Document composition and boundaries
workspaces/api-tryit/hurl-parser/src/hurl-collection-file.ts, workspaces/api-tryit/hurl-parser/tests/hurl-parser.test.ts
The parser composes non-empty cells and reports source indices with 1-based line boundaries. Tests cover ordering, blank cells, and comment-only cells.
Runner options and result mapping
workspaces/api-tryit/hurl-runner/src/types.ts, workspaces/api-tryit/hurl-runner/src/hurl-runner.ts, workspaces/api-tryit/hurl-runner/src/report-parser.ts, workspaces/api-tryit/hurl-runner/tests/*
Hurl runs accept ordered variable files and extra arguments. File results map to cell outcomes by line boundaries, with fallback handling for unmatched and lineless entries.
Combined notebook execution and output
workspaces/hurl-client/hurl-client-extension/src/notebook/HurlNotebookController.ts
The controller runs non-empty cells together, assigns per-cell statuses and timings, detects undefined variables, indexes assertions, and formats response output.
Extension settings and documentation
workspaces/hurl-client/hurl-client-extension/package.json, workspaces/hurl-client/hurl-client-extension/README.md
The extension adds resource-scoped settings for variables, TLS verification, redirects, and extra Hurl arguments. Documentation describes chaining and variable files.

Pull request overview

This PR improves the Hurl Client notebook execution model by running selected cells as a single chained hurl invocation (so captured variables flow across requests), and adds runner/parser support to map multi-entry results back to the originating notebook cells. It also introduces variables-file / extra CLI args support and updates tests and documentation accordingly.

Changes:

  • Execute selected notebook cells as one combined “chained run”, then map per-entry results back to per-cell outputs using boundary/line-range attribution.
  • Add support for shared/per-file variables files, TLS/redirect flags, and passthrough CLI args in the runner + extension settings.
  • Add/extend unit tests for boundary mapping and runner argument construction; refresh docs and some metadata.

- Do not discard report entries whose line cannot be resolved once every
  cell boundary is claimed; attach them to the last boundary so an executed
  request never disappears from the notebook, and cover it with a test.
- Distinguish a comments-only cell from one holding content that parsed to
  no request. A malformed request previously ended its cell successfully,
  masking the error; it now fails with a "NOT PARSED" output.
- Drop the leftover deprecated onCommand activation event. Contributed
  commands are auto-activated from VS Code 1.74 and this extension targets
  ^1.100.0, so neither importHurlString entry is needed.
- Document that hurl.vars is resolved from hurl-client.fileRoot (defaulting
  to the notebook folder), and tag the variables-file example as ini.

hurl-client.fileRoot is free-text configuration, so it can hold a
relative path. It was used verbatim, which made it resolve against the
extension host's process cwd - neither the notebook nor the workspace.
The shared hurl.vars lookup then missed, was skipped without a message,
and the run failed on undefined variables with no indication why. The
same value is passed to hurl as --file-root, so file references inside
requests were mis-rooted too.

Relative values now resolve against the workspace folder owning the
notebook, the usual VS Code convention for a resource-scoped path
setting, falling back to the notebook's folder when it sits outside any
workspace folder. Absolute values are unchanged.
