Subject: [PATCH 2/7] Add literal() function to preserve apostrophes in shell
 arguments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #141 - Apostrophes in text arguments are over-escaped, appearing
as triple quotes (''') when stored literally by receiving programs.

## Problem

When passing text containing apostrophes through command-stream, the
default quote() function uses Bash's '\'' escaping pattern. While
correct for shell interpretation, when the receiving program (like gh
CLI) passes text to an API that stores it literally, the escape
sequences appear as visible characters (''').

## Solution

Add two new functions:
- `literal(value)` - Mark text for double-quote escaping, preserving
  apostrophes while still escaping shell-dangerous characters ($, `, \, ")
- `quoteLiteral(value)` - Low-level function for manual command building

## Usage

```javascript
import { $, literal } from 'command-stream';

// Problem: default escaping
await $`gh release create --notes ${text}`;  // didn't → didn'''t

// Solution: use literal()
await $`gh release create --notes ${literal(text)}`;  // didn't stays didn't
```

## Changes

- js/src/$.mjs: Add quoteLiteral() and literal() functions
- js/tests/$.test.mjs: Add 15 new tests for quoteLiteral and literal
- README.md: Add documentation for literal() and quoteLiteral()
- docs/case-studies/issue-141/: Case study with root cause analysis
- experiments/: Test scripts for verification
- eslint.config.js: Add experiments/ to lenient rules

+### Preserving Apostrophes with `literal()` (Advanced)
+
+When passing text to programs that store it literally (like API calls via CLI tools), apostrophes can appear corrupted as triple quotes (`'''`). This happens because the default `quote()` function uses Bash's `'\''` escaping pattern for apostrophes.
+
+Use `literal()` to preserve apostrophes when the receiving program stores text literally:
+
+```javascript
+import { $, literal } from 'command-stream';
+
+// Problem: Default escaping uses '\'' pattern for apostrophes
+const releaseNotes = "Fix bug when dependencies didn't exist";
+await $`gh release create v1.0.0 --notes ${releaseNotes}`;
+// Apostrophe may appear as ''' in GitHub if the API stores it literally
+
+// Solution: Use literal() to preserve apostrophes
+await $`gh release create v1.0.0 --notes ${literal(releaseNotes)}`;
+// Apostrophe stays as ' - text displays correctly on GitHub
+
+// literal() still escapes shell-dangerous characters
+const text = "User's input with $variable and `backticks`";
+await $`command ${literal(text)}`;
+// $ and ` are escaped, but apostrophe stays as-is
+```
+
+**How `literal()` differs from `raw()` and default quoting:**
+
+| Function    | Apostrophe `'` | Shell Chars `$ \` "` | Safety Level |
+| ----------- | -------------- | -------------------- | ------------ |
+| Default     | `'\''` escaped | Safely quoted        | ✅ Maximum   |
+| `literal()` | Preserved      | Escaped              | ✅ Safe      |
+| `raw()`     | Preserved      | NOT escaped          | ⚠️ Dangerous |
+
+**When to use `literal()`:**
+
+- ✅ Text for APIs via CLI tools (GitHub, cloud CLIs)
+- ✅ Release notes, commit messages, descriptions
+- ✅ Any text that will be stored/displayed literally
+- ✅ When apostrophes appear as `'''` in the output
+
+**Recommended Alternative: Use stdin for APIs**
+
+For API calls, the safest approach is to pass data via stdin:
+
+```javascript
+const payload = JSON.stringify({
+  tag_name: 'v1.0.0',
+  body: releaseNotes, // No escaping issues!
+});
+
+await $`gh api repos/owner/repo/releases -X POST --input -`.run({
+  stdin: payload,
+});
+```

+# Case Study: Apostrophe Over-Escaping (Issue #141)
+
+## Overview
+
+This case study documents the issue where apostrophes in text arguments are over-escaped when passed through command-stream, causing them to appear as triple quotes (`'''`) when the text is stored or displayed literally by receiving programs.
+
+## Problem Statement
+
+When passing text containing apostrophes through command-stream in double-quoted template literals, apostrophes are escaped using Bash's `'\''` pattern. When the receiving command (like `gh` CLI) passes this text to an API that stores it literally, the escape sequences appear as visible characters.
+
+### Example
+
+```javascript
+const releaseNotes = "Fix bug when dependencies didn't exist";
+await $`gh release create v1.0.0 --notes "${releaseNotes}"`;
+// GitHub receives: "Fix bug when dependencies didn'\''t exist"
+// GitHub displays: "Fix bug when dependencies didn'''t exist"
+```
+
+## Timeline of Investigation
+
+1. **Initial report**: Issue observed in production with GitHub release notes
+2. **Related issue**: First documented in test-anywhere repository (issue #135)
+3. **Workaround implemented**: Using `gh api` with JSON stdin instead of shell arguments
+4. **Root cause identified**: Double-quoting when users add quotes around interpolated values
+
+## Root Cause Analysis
+
+### The Escaping Mechanism
+
+The `quote()` function in command-stream (js/src/$.mjs:1056-1100) handles shell escaping:
+
+```javascript
+function quote(value) {
+  // ... null/array handling ...
+
+  // Default: wrap in single quotes, escape internal single quotes
+  return `'${value.replace(/'/g, "'\\''")}'`;
+}
+```
+
+For input `didn't`, this produces `'didn'\''t'`, which is the correct Bash escaping for a single quote inside a single-quoted string.
+
+### The Double-Quoting Issue
+
+When users write:
+```javascript
+await $`command "${text}"`;
+```
+
+The template literal contains `"` characters as static strings. The `buildShellCommand()` function then:
+1. Adds the static string `command "`
+2. Calls `quote(text)` which wraps in single quotes
+3. Adds the closing static string `"`
+
+Result: `command "'escaped'\''text'"`
+
+This creates double-quoting - the user's `"..."` plus the library's `'...'`.
+
+### Experimental Evidence
+
+```
+Test: Direct shell (baseline)
+Command: /tmp/show-args.sh "Text with apostrophe's"
+Result: [Text with apostrophe's] ✅
+
+Test: With user-provided quotes (the bug)
+Command: $`/tmp/show-args.sh "${testText}"`
+Result: ['Dependencies didn'\''t exist'] ❌
+
+Test: Without user quotes (correct usage)
+Command: $`/tmp/show-args.sh ${testText}`
+Result: [Dependencies didn't exist] ✅
+```
+
+### Why Triple Quotes Appear
+
+When a program receives `'didn'\''t'`:
+1. If it **interprets** as shell → expands to `didn't` ✅
+2. If it **stores literally** → keeps as `'didn'\''t'` which displays as `didn'''t` ❌
+
+The `gh` CLI passes arguments to GitHub's API, which stores them literally without shell interpretation.
+
+## Solutions
+
+### Solution 1: Correct Usage (No User Quotes)
+
+The simplest solution is to not add quotes around interpolated values:
+
+```javascript
+// ❌ Wrong - double quoting
+await $`gh release create --notes "${text}"`;
+
+// ✅ Correct - let command-stream quote
+await $`gh release create --notes ${text}`;
+```
+
+### Solution 2: literal() Function (Proposed)
+
+Add a `literal()` function for cases where text should not be shell-escaped:
+
+```javascript
+import { $, literal } from 'command-stream';
+
+// Mark text as literal - minimal escaping for argument boundary only
+await $`gh release create --notes ${literal(releaseNotes)}`;
+```
+
+This would:
+- Apply only the minimal escaping needed for argument boundaries
+- Not apply Bash-specific patterns like `'\''`
+- Be useful when the receiving program stores text literally
+
+### Solution 3: Use stdin with JSON (Recommended for APIs)
+
+For API calls, pass data via stdin:
+
+```javascript
+const payload = JSON.stringify({
+  tag_name: 'v1.0.0',
+  body: releaseNotes,
+});
+
+await $`gh api repos/owner/repo/releases -X POST --input -`.run({
+  stdin: payload,
+});
+```
+
+This completely bypasses shell escaping issues.
+
+## Implementation Decision
+
+Based on the issue suggestions and analysis:
+
+1. **Implement `literal()` function** - For marking text that should not be shell-escaped
+2. **Improve documentation** - Clarify when and how shell escaping occurs
+3. **Add examples** - Show correct usage patterns and workarounds
+
+## Related Issues and References
+
+- **Issue #141**: This issue - Apostrophe over-escaping
+- **Issue #45**: Automatic quote addition in interpolation
+- **Issue #49**: Complex shell commands with nested quotes
+- **test-anywhere #135**: First observed occurrence
+- **test-anywhere PR #136**: Workaround using stdin/JSON
+
+## Lessons Learned
+
+1. Shell escaping and literal text storage are incompatible
+2. Users should not add quotes around interpolated values
+3. For API calls, JSON/stdin is the safest approach
+4. Clear documentation and examples are essential
+
+## Test Cases
+
+A proper fix should handle:
+
+| Input | Expected Output |
+|-------|-----------------|
+| `didn't` | `didn't` |
+| `it's user's choice` | `it's user's choice` |
+| `text is "quoted"` | `text is "quoted"` |
+| `it's "great"` | `it's "great"` |
+| `` use `npm` `` | `` use `npm` `` |
+| `Line 1\nLine 2` | `Line 1\nLine 2` |

+
+Add `literal()` function to preserve apostrophes in shell arguments
+
+When passing text containing apostrophes to programs that store it literally (like API calls via CLI tools), apostrophes would appear corrupted as triple quotes (`'''`). The new `literal()` function uses double-quote escaping which preserves apostrophes while still escaping shell-dangerous characters.
+
+**New features:**
+- `literal(value)` - Mark text for double-quote escaping, preserving apostrophes
+- `quoteLiteral(value)` - Low-level function for manual command building
+
+**Usage:**
+```javascript
+import { $, literal } from 'command-stream';
+
+// Apostrophes now preserved for API storage
+const notes = "Dependencies didn't exist";
+await $`gh release create --notes ${literal(notes)}`;
+```

 Add `literal()` function to preserve apostrophes in shell arguments
@@ -7,10 +7,12 @@ Add `literal()` function to preserve apostrophes in shell arguments
 When passing text containing apostrophes to programs that store it literally (like API calls via CLI tools), apostrophes would appear corrupted as triple quotes (`'''`). The new `literal()` function uses double-quote escaping which preserves apostrophes while still escaping shell-dangerous characters.
 
 **New features:**
+
 - `literal(value)` - Mark text for double-quote escaping, preserving apostrophes
 - `quoteLiteral(value)` - Low-level function for manual command building
 
 **Usage:**
+
 ```javascript
 import { $, literal } from 'command-stream';
