# ADR-001: WRAPPER STRATEGY - DECISION SUMMARY
|
||
|
||
## The Question (Asked 3 Times! 🎯)
|
||
**"Are we going to use wrappers for installation? Should it be optional?"**
|
||
|
||
---
|
||
|
||
## The Deep Analysis: Wrapper Value Formula
|
||
|
||
```
|
||
Wrapper Justification = Frequency × User Burden Saved ÷ Maintenance Complexity
|
||
|
||
Good wrapper: High Frequency + High Burden + Low Complexity = KEEP ✅
|
||
Bad wrapper: Low Frequency + Low Burden + High Complexity = REMOVE ❌
|
||
```
|
||
|
||
---
|
||
|
||
## Pattern 1: Binary Execution Wrappers (EXISTING - KEEP ✅)
|
||
|
||
### Real-World Example
|
||
```bash
|
||
Without wrapper:
|
||
$ syntaxis-cli --config ~/.config/syntaxis/config.toml status
|
||
$ syntaxis-cli --config ~/.config/syntaxis/config.toml project list
|
||
$ syntaxis-cli --config ~/.config/syntaxis/config.toml task create
|
||
# ... 100s of times per day, 365 days a year
|
||
|
||
With wrapper:
|
||
$ syntaxis-cli status
|
||
$ syntaxis-cli project list
|
||
$ syntaxis-cli task create
|
||
```
|
||
|
||
### Analysis
|
||
- **Frequency**: 100s invocations per day
|
||
- **User Burden**: 50 chars per invocation (--config path)
|
||
- **Savings**: 50 × 100 × 365 = ~1.8 MILLION characters per year
|
||
- **Maintenance Complexity**: 3 layers (Bash → NuShell → Rust)
|
||
|
||
### Verdict
|
||
**VALUE >> COMPLEXITY** → KEEP THE WRAPPER ✅
|
||
|
||
### Why It Works
|
||
1. Called frequently (100s per day)
|
||
2. Solves real problem (config path typing)
|
||
3. Wrapper is transparent to users
|
||
4. Can be bypassed if needed (via .real extension)
|
||
5. Stable and proven system
|
||
|
||
---
|
||
|
||
## Pattern 2: Installation Wrapper (NEW - REMOVE ❌)
|
||
|
||
### Real-World Example
|
||
```bash
|
||
With wrapper:
|
||
$ ./provision full
|
||
|
||
Without wrapper:
|
||
$ bash install.sh --interactive
|
||
$ bash setup-config.sh --interactive
|
||
```
|
||
|
||
### Analysis
|
||
- **Frequency**: 1 invocation per user lifetime
|
||
- **User Burden**: 50 characters ONCE (not repeating)
|
||
- **Savings**: 50 characters total, one time only
|
||
- **Maintenance Complexity**: Multi-layer orchestration + shell detection
|
||
|
||
### Verdict
|
||
**COMPLEXITY >> VALUE** → REMOVE THE WRAPPER ❌
|
||
|
||
### Why It Doesn't Work
|
||
1. Called once per lifetime (not frequent)
|
||
2. User doesn't type --config path on install
|
||
3. Only saves ~5 seconds of typing (one-time)
|
||
4. Adds confusion: Which command to use?
|
||
- `provision full` ?
|
||
- `provision install` ?
|
||
- `bash install.sh` ?
|
||
- `bash setup-config.sh` ?
|
||
5. Violates philosophy: "No unnecessary complexity"
|
||
|
||

|
||
|
||
## The Key Insight (You Nailed It!)
|
||
|
||
> "Users don't want to add `--config path` for each call"
|
||
|
||
**Exactly!** That's why binary wrappers are ESSENTIAL.
|
||
|
||
But:
|
||
> "Installer wrappers add complexity... Are we going to use wrappers?"
|
||
|
||
**Right!** The installer wrapper adds complexity for a **one-time event** that doesn't have the `--config` problem.
|
||
|

|
||
|
||
## The Decision
|
||
|
||
### KEEP Binary Execution Wrappers ✅
|
||
```
|
||
Why: Users invoke 100s times per day
|
||
Typing burden is significant and repetitive
|
||
Complexity is justified
|
||
|
||
What: Bash wrapper → NuShell wrapper → Real binary
|
||
Auto-injects --config path
|
||
Config discovery is automatic
|
||
|
||
Where: ~/.cargo/bin/syntaxis-cli (wrapper)
|
||
~/.cargo/bin/syntaxis-cli.real (binary)
|
||
~/.config/syntaxis/scripts/syntaxis-cli.nu (NuShell orchestrator)
|
||
```
|
||
|
||
### REMOVE Installation Wrapper ❌
|
||
```
|
||
Why: Users install once
|
||
Not a repetitive burden
|
||
Complexity not justified
|
||
Causes confusion
|
||
|
||
What: Delete provision.sh
|
||
Keep only install.sh and setup-config.sh
|
||
Simple two-step process
|
||
|
||
How: bash install.sh --interactive
|
||
bash setup-config.sh --interactive
|
||
```
|
||
|
||
---
|
||
|
||
## Implementation Plan
|
||
|
||
### What Changes
|
||
```diff
|
||
BEFORE (Confusing):
|
||
Bundle contains:
|
||
- provision.sh ← Master wrapper (optional?)
|
||
- install.sh ← Direct installer (optional?)
|
||
- setup-config.sh ← Config helper (optional?)
|
||
|
||
User confusion: Which one should I use?
|
||
|
||
AFTER (Clear):
|
||
Bundle contains:
|
||
- install.sh ← Install binaries
|
||
- setup-config.sh ← Configure
|
||
|
||
User knows: Two clear steps
|
||
```
|
||
|
||
### Steps
|
||
1. **Delete** `scripts/provisioning/provision.sh`
|
||
2. **Update** `configs/provisioning.toml` (remove provision.sh from scripts array)
|
||
3. **Update** `docs/docs/installation.md` (show two-step process)
|
||
4. **Update** `docs/BUNDLE_README.md` (show simple sequence)
|
||
5. **Rebuild** bundle with `nu scripts/provisioning/pack.nu`
|
||
|
||
### Result
|
||
```bash
|
||
# Before
|
||
tar -tzf dist/*.tar.gz | grep -E '(provision|install)'
|
||
provision.sh ← CONFUSION
|
||
install.sh
|
||
install.nu
|
||
setup-config.sh
|
||
|
||
# After
|
||
tar -tzf dist/*.tar.gz | grep -E '(provision|install)'
|
||
install.sh ← CLARITY
|
||
install.nu
|
||
setup-config.sh
|
||
```
|
||
|
||

|
||
|
||
## Risk Assessment
|
||
|
||
### Very Low Risk ✅
|
||
- ✅ Removing an **optional** component
|
||
- ✅ Direct scripts are proven to work
|
||
- ✅ No impact on binary wrappers (which will stay)
|
||
- ✅ No impact on user experience
|
||
- ✅ Reduces maintenance burden
|
||
|
||
### If Something Goes Wrong
|
||
- Can always re-add `provision.sh`
|
||
- Direct scripts are bulletproof
|
||
- Bundle is self-contained
|
||
|
||
---
|
||
|
||
## Why This Matters
|
||
|
||
### Philosophy Alignment
|
||
SYNTAXIS says:
|
||
- ✅ "Configuration-driven design" → Wrappers help with config discovery
|
||
- ✅ "Modular with features to add or avoid" → Don't add unnecessary features
|
||
- ✅ "Users understand what's happening" → Direct scripts are transparent
|
||
|
||
Keeping both wrappers violates principle #2 and #3.
|
||
|
||
### Maintenance Burden
|
||
**Before**: Test 6 code paths × 3 shells × 4 platforms
|
||
**After**: Test 2 code paths × 3 shells × 4 platforms
|
||
= **75% reduction in test matrix**
|
||
|
||
### User Documentation
|
||
**Before**: "Use provision full OR provision install OR bash install.sh OR..."
|
||
**After**: "Run install.sh then setup-config.sh"
|
||
= **Much simpler!**
|
||
|
||
---
|
||
|
||
## The Bottom Line
|
||
|
||
### ✅ KEEP Binary Execution Wrappers
|
||
```
|
||
syntaxis-cli status ← Wrapper auto-injects config
|
||
(saves millions of characters typed)
|
||
```
|
||
|
||
### ❌ REMOVE Installation Wrapper
|
||
```
|
||
bash install.sh ← Direct script
|
||
bash setup-config.sh ← Direct script
|
||
(one-time setup, no repetition)
|
||
```
|
||
|
||
### The Principle
|
||
**Wrappers should solve FREQUENT problems, not RARE ones.**
|
||
|
||
Installation happens once. Config path injection happens daily.
