fix(coding-agent): keep grep context lines aligned with ripgrep when a file has a lone CR (#11465)
When `context` is set, the grep tool reads the file again to print the
lines around each match. It turned CRLF into LF and also turned every
lone CR into LF before splitting the text into lines. ripgrep, which
supplies the match line numbers, counts lines only at LF. A lone CR
therefore added an extra line on pi's side, so every later line was off
by one.

For example, in a file containing `before\rprogress\nneedle\nafter`, a
search for `needle` with `context: 1` showed `progress` as the line-2
match and left out `after`.

The fix keeps the CRLF normalization and splits only on LF, so pi
numbers lines the same way ripgrep does. Displayed lines already have
`\r` removed, so the line before the match now shows as
`beforeprogress`.

**Testing**
- Added a test in `packages/coding-agent/test/tools.test.ts` for a file
with a lone CR searched with `context: 1`. It fails without the fix and
passes with it.
- `test/tools.test.ts`: all 87 tests pass.
- `npm run check` passes.
- Reproduction from the issue. Before the fix:
  ```
  f.txt-1- before
  f.txt:2: progress
  f.txt-3- needle
  ```
  After the fix:
  ```
  f.txt-1- beforeprogress
  f.txt:2: needle
  f.txt-3- after
  ```

Fixes #11398

Pi

Pi is a minimal, extensible agent harness that you can make your own.

Adapt Pi to your workflows, not the other way around. Customize Pi with extensions, skills, prompt templates, and themes. Bundle them as Pi packages and share via npm or git.

Pi ships with powerful defaults but skips features like sub-agents and plan mode. Ask Pi to build what you want, or install a package that does it your way.

Use Pi interactively, automate it in print or JSON mode, control it over RPC, or build apps with the Pi TypeScript SDK. See OpenClaw for a real-world integration.

Getting started

Install the command-line interface:

curl -fsSL https://pi.dev/install.sh | sh

On Windows:

powershell -c "irm https://pi.dev/install.ps1 | iex"

The installer pins all dependencies and updates Pi with pi update. Alternatively, install directly with npm, which does not pin transitive dependencies:

npm install -g --ignore-scripts @earendil-works/pi-coding-agent

Pi requires Node.js 22.19 or newer. The macOS, Linux, and Windows installers can install it if needed. Pi does not require dependency lifecycle scripts for a normal npm installation.

On macOS and Linux, Nix users can install the latest release with nix profile add github:earendil-works/pi/stable. See the quickstart for updating and pinning releases.

Start Pi in the directory where you want it to work:

cd /path/to/project
pi

For a built-in AI provider, run /login inside Pi to connect a subscription or API key. Then give Pi a task.

See the documentation for full setup and usage instructions.

Share your OSS coding agent sessions

If you use Pi for open source work, please share your coding agent sessions.

Public OSS session data helps improve models, prompts, tools, and evaluations using real development workflows.

For the full explanation, see this post on X.

To publish sessions, use badlogic/pi-share-hf using a Hugging Face account and the Hugging Face CLI.

Development

Clone the repository, install its dependencies, and run Pi from source:

git clone https://github.com/earendil-works/pi
cd pi
npm install --ignore-scripts
./pi-test.sh

pi-test.sh can be called from any directory and preserves the caller's working directory.

Before submitting changes, run:

npm run check
./test.sh
