make setup
# Update and verify vendored dependencies
make vendor-update
```
## Architecture Overview
The `cheat` command-line tool is organized into several key packages:
### Command Layer (`cmd/cheat/`)
- `main.go`: Entry point, argument parsing, command routing
- `cmd_*.go`: Individual command implementations (view, edit, list, search, etc.)
- Commands are selected based on docopt parsed arguments
### Core Internal Packages
1. **`internal/config`**: Configuration management
- Loads YAML config from platform-specific paths
- Manages editor, pager, colorization settings
- Validates and expands cheatpath configurations
2. **`internal/cheatpath`**: Cheatsheet path management
- Represents collections of cheatsheets on filesystem
- Handles read-only vs writable paths
- Supports filtering and validation
3. **`internal/sheet`**: Individual cheatsheet handling
- Parses YAML frontmatter for tags and syntax
- Implements syntax highlighting via Chroma
- Provides search functionality within sheets
4. **`internal/sheets`**: Collection operations
- Loads sheets from multiple cheatpaths
- Consolidates duplicates (local overrides global)
- Filters by tags and sorts results
5. **`internal/display`**: Output formatting
- Writes to stdout or pager
- Handles text formatting and indentation
6. **`internal/installer`**: First-run installer
- Prompts user for initial configuration choices
- Generates default `conf.yml` and downloads community cheatsheets
7. **`internal/repo`**: Git repository management
- Clones community cheatsheet repositories
- Updates existing repositories
### Key Design Patterns
- **Filesystem-based storage**: Cheatsheets are plain text files
- **Override mechanism**: Local sheets override community sheets with same name
- **Tag system**: Sheets can be categorized with tags in frontmatter
- **Multiple cheatpaths**: Supports personal, community, and directory-scoped sheets
- **Directory-scoped discovery**: Walks up from cwd to find the nearest `.cheat` directory (like `.git` discovery)
### Sheet Format
Cheatsheets are plain text files optionally prefixed with YAML frontmatter:
```
---
syntax: bash
tags: [ networking, ssh ]
---
# SSH tunneling example
ssh -L 8080:localhost:80 user@remote
```
### Working with the Codebase
- Always check for `.git` directories and skip them during filesystem walks
- Use `go-git` for repository operations, not exec'ing git commands
- Platform-specific paths are handled in `internal/config/paths.go`
- Color output uses ANSI codes via the Chroma library
- Test files use the `mocks` package for test data

# Contributing
CONTRIBUTING
============
Do you want to contribute to `cheat`? There are a few ways to help:
Thank you for your interest in `cheat`.
#### Submit a cheatsheet ####
Do you have a witty bash one-liner to share? [Open a pull-request][pr] against
the [cheatsheets][] repository. (The `cheat` executable source code lives in
[cheat/cheat][cheat]. Cheatsheet content lives in
[cheat/cheatsheets][cheatsheets].)
Pull requests are no longer being accepted, and have been disabled on this
repository. The maintainer is not currently reviewing or merging external code
contributions.
#### Report a bug ####
Did you find a bug? Report it in the [issue tracker][issues]. (But before you
do, please look through the open issues to make sure that it hasn't already
been reported.)
Bug reports are still welcome. If you've found a bug, please open an issue in
the [issue tracker][issues]. Before doing so, please search through the
existing open issues to make sure it hasn't already been reported.
#### Add a feature ####
Do you have a feature that you'd like to contribute? Propose it in the [issue
tracker][issues] to discuss with the maintainer whether it would be considered
for merging.
Feature requests may be filed, but are unlikely to be implemented. The project
is now mature and the maintainer considers its feature set to be essentially
complete.
`cheat` is mostly mature and feature-complete, but may still have some room for
new features.
#### Add documentation ####
Did you encounter features, bugs, edge-cases, use-cases, or environment
considerations that were undocumented or under-documented? Add them to the
[wiki][]. (You may also open a pull-request against the `README`, if
appropriate.)
Do you enjoy technical writing or proofreading? Help keep the documentation
error-free and well-organized.
#### Spread the word ####
Are you unable to do the above, but still want to contribute? You can help
`cheat` simply by telling others about it. Share it with friends and coworkers
that might benefit from using it.

# Hacking Guide
This document provides a comprehensive guide for developing `cheat`, including setup, architecture overview, and code patterns.
## Quick Start
### 1. Install system dependencies
The following are required and must be available on your `PATH`:
- `git`
- `go` (>= 1.19 is recommended)
- `make`
Optional dependencies:
- `docker`
- `pandoc` (necessary to generate a `man` page)
### 2. Install utility applications
Run `make setup` to install `scc` and `revive`, which are used by various `make` targets.
### 3. Development workflow
1. Make changes to the `cheat` source code
2. Run `make test` to run unit-tests
3. Fix compiler errors and failing tests as necessary
4. Run `make build`. A `cheat` executable will be written to the `dist` directory
5. Use the new executable by running `dist/cheat <command>`
6. Run `make install` to install `cheat` to your `PATH`
7. Run `make build-release` to build cross-platform binaries in `dist`
8. Run `make clean` to clean the `dist` directory when desired
You may run `make help` to see a list of available `make` commands.
### 4. Testing
#### Unit Tests
Run unit tests with:
```bash
make test
```
#### Integration Tests
Integration tests that require network access are separated using build tags. Run them with:
```bash
make test-integration
```
To run all tests (unit and integration):
```bash
make test-all
```
#### Test Coverage
Generate a coverage report with:
```bash
make coverage # HTML report
make coverage-text # Terminal output
```
## Architecture Overview
### Package Structure
The `cheat` application follows a clean architecture with well-separated concerns:
- **`cmd/cheat/`**: Command layer with argument parsing and command routing
- **`internal/config`**: Configuration management (YAML loading, validation, paths)
- **`internal/cheatpath`**: Cheatsheet path management (collections, filtering)
- **`internal/sheet`**: Individual cheatsheet handling (parsing, search, highlighting)
- **`internal/sheets`**: Collection operations (loading, consolidation, filtering)
- **`internal/display`**: Output formatting (pager integration, colorization)
- **`internal/repo`**: Git repository management for community sheets
### Key Design Patterns
- **Filesystem-based storage**: Cheatsheets are plain text files
- **Override mechanism**: Local sheets override community sheets with same name
- **Tag system**: Sheets can be categorized with tags in frontmatter
- **Multiple cheatpaths**: Supports personal, community, and directory-scoped sheets
## Core Types and Functions
### Config (`internal/config`)
The main configuration structure:
```go
type Config struct {
Colorize bool `yaml:"colorize"`
Editor string `yaml:"editor"`
Cheatpaths []cp.Path `yaml:"cheatpaths"`
Style string `yaml:"style"`
Formatter string `yaml:"formatter"`
Pager string `yaml:"pager"`
Path string
}
```
Key functions:
- `New(confPath, resolve)` - Load config from file
- `Validate()` - Validate configuration values
- `Editor()` - Get editor from environment or defaults (package-level function)
- `Pager()` - Get pager from environment or defaults (package-level function)
### Cheatpath (`internal/cheatpath`)
Represents a directory containing cheatsheets:
```go
type Path struct {
Name string // Friendly name (e.g., "personal")
Path string // Filesystem path
Tags []string // Tags applied to all sheets in this path
ReadOnly bool // Whether sheets can be modified
}
```
### Sheet (`internal/sheet`)
Represents an individual cheatsheet:
```go
type Sheet struct {
Title string // Sheet name (from filename)
CheatPath string // Name of the cheatpath this sheet belongs to
Path string // Full filesystem path
Text string // Content (without frontmatter)
Tags []string // Combined tags (from frontmatter + cheatpath)
Syntax string // Syntax for highlighting
ReadOnly bool // Whether sheet can be edited
}
```
Key methods:
- `New(title, cheatpath, path, tags, readOnly)` - Load from file
- `Search(reg)` - Search content with a compiled regexp
- `Colorize(conf)` - Apply syntax highlighting (modifies sheet in place)
- `Tagged(needle)` - Check if sheet has the given tag
## Common Operations
### Loading and Displaying a Sheet
```go
// Load sheet
s, err := sheet.New("tar", "personal", "/path/to/tar", []string{"personal"}, false)
if err != nil {
log.Fatal(err)
}
// Apply syntax highlighting (modifies sheet in place)
s.Colorize(conf)
// Display with pager
display.Write(s.Text, conf)
```
### Working with Sheet Collections
```go
// Load all sheets from cheatpaths (returns a slice of maps, one per cheatpath)
allSheets, err := sheets.Load(conf.Cheatpaths)
if err != nil {
log.Fatal(err)
}
// Consolidate to handle duplicates (later cheatpaths take precedence)
consolidated := sheets.Consolidate(allSheets)
// Filter by tag (operates on the slice of maps)
filtered := sheets.Filter(allSheets, []string{"networking"})
// Sort alphabetically (returns a sorted slice)
sorted := sheets.Sort(consolidated)
```
### Sheet Format
Cheatsheets are plain text files that may begin with YAML frontmatter:
```yaml
---
syntax: bash
tags: [networking, linux, ssh]
---
# Connect to remote server
ssh user@hostname
# Copy files over SSH
scp local_file user@hostname:/remote/path
```
## Testing
Run tests with:
```bash
make test # Run all tests
make coverage # Generate coverage report
go test ./... # Go test directly
```
Test files follow Go conventions:
- `*_test.go` files in same package
- Table-driven tests for multiple scenarios
- Mock data in `mocks` package
## Error Handling
The codebase follows consistent error handling patterns:
- Functions return explicit errors
- Errors are wrapped with context using `fmt.Errorf`
- User-facing errors are written to stderr
Example:
```go
sheet, err := sheet.New(path, tags, false)
if err != nil {
return fmt.Errorf("failed to load sheet: %w", err)
}
```
## Developing with Docker
It may be useful to test your changes within a pristine environment. An Alpine-based docker container has been provided for that purpose.
Build the docker container:
```bash
make docker-setup
```
Shell into the container:
```bash
make docker-sh
```
The `cheat` source code will be mounted at `/app` within the container.
To destroy the container:
```bash
make distclean
```

# Installing
`cheat` has no runtime dependencies. As such, installing it is generally
straightforward. There are a few methods available:
## Install manually
### Unix-like
On Unix-like systems, you may simply paste the following snippet into your terminal:
```sh
cd /tmp \
&& wget https://github.com/cheat/cheat/releases/download/4.7.0/cheat-linux-amd64.gz \
&& gunzip cheat-linux-amd64.gz \
&& chmod +x cheat-linux-amd64 \
&& sudo mv cheat-linux-amd64 /usr/local/bin/cheat
```
You may need to need to change the version number (`4.7.0`) and the archive
(`cheat-linux-amd64.gz`) depending on your platform.
See the [releases page][releases] for a list of supported platforms.
### Windows
On Windows, download the appropriate binary from the [releases page][releases],
unzip the archive, and place the `cheat.exe` executable on your `PATH`.
## Install via `go install`
If you have `go` version `>=1.17` available on your `PATH`, you can install
`cheat` via `go install`:
```sh
go install github.com/cheat/cheat/cmd/cheat@latest
```
## Install via package manager
Several community-maintained packages are also available:
Package manager | Package(s)
---------------- | -----------
aur | [cheat][pkg-aur-cheat], [cheat-bin][pkg-aur-cheat-bin]
brew | [cheat][pkg-brew]
docker | [docker-cheat][pkg-docker]
nix | [nixos.cheat][pkg-nix]
snap | [cheat][pkg-snap]
## Configuring
Three things must be done before you can use `cheat`:
1. A config file must be generated
2. [`cheatpaths`][cheatpaths] must be configured
3. [Community cheatsheets][community] must be downloaded
On first run, `cheat` will run an installer that will do all of the above
automatically. After the installer is complete, it is strongly advised that you
view the configuration file that was generated, as you may want to change some
of its default values (to enable colorization, change the paginator, etc).
### conf.yml
`cheat` is configured by a YAML file that will be auto-generated on first run.
By default, the config file is assumed to exist on an XDG-compliant
configuration path like `~/.config/cheat/conf.yml`. If you would like to store
it elsewhere, you may export a `CHEAT_CONFIG_PATH` environment variable that
specifies its path:
```sh
export CHEAT_CONFIG_PATH="~/.dotfiles/cheat/conf.yml"

## Installing
For installation and configuration instructions, see [INSTALLING.md][].
## Usage
Installing
----------
`cheat` has no dependencies. To install it, download the executable from the
[releases][] page and place it on your `PATH`.
Configuring
-----------
### conf.yml ###
`cheat` is configured by a YAML file that will be auto-generated on first run.
Should you need to create a config file manually, you can do
so via:
```sh
mkdir -p ~/.config/cheat && cheat --init > ~/.config/cheat/conf.yml
```
By default, the config file is assumed to exist on an XDG-compliant
configuration path like `~/.config/cheat/conf.yml`. If you would like to store
it elsewhere, you may export a `CHEAT_CONFIG_PATH` environment variable that
specifies its path:
```sh
export CHEAT_CONFIG_PATH="~/.dotfiles/cheat/conf.yml"
```
Cheatsheets
-----------
Cheatsheets are plain-text files with no file extension, and are named
according to the command used to view them:
```sh
cheat tar # file is named "tar"
cheat foo/bar # file is named "bar", in a "foo" subdirectory
```
Cheatsheet text may optionally be preceeded by a YAML frontmatter header that
assigns tags and specifies syntax:
```
---
syntax: javascript
tags: [ array, map ]
---
// To map over an array:
const squares = [1, 2, 3, 4].map(x => x * x);
```
The `cheat` executable includes no cheatsheets, but [community-sourced
cheatsheets are available][cheatsheets]. You will be asked if you would like to
install the community-sourced cheatsheets the first time you run `cheat`.
Cheatpaths
----------
Cheatsheets are stored on "cheatpaths", which are directories that contain
cheatsheets. Cheatpaths are specified in the `conf.yml` file.
It can be useful to configure `cheat` against multiple cheatpaths. A common
pattern is to store cheatsheets from multiple repositories on individual
cheatpaths:
```yaml
# conf.yml:
# ...
cheatpaths:
- name: community # a name for the cheatpath
path: ~/documents/cheat/community # the path's location on the filesystem
tags: [ community ] # these tags will be applied to all sheets on the path
readonly: true # if true, `cheat` will not create new cheatsheets here
- name: personal
path: ~/documents/cheat/personal # this is a separate directory and repository than above
tags: [ personal ]
readonly: false # new sheets may be written here
# ...
```
The `readonly` option instructs `cheat` not to edit (or create) any cheatsheets
on the path. This is useful to prevent merge-conflicts from arising on upstream
cheatsheet repositories.
If a user attempts to edit a cheatsheet on a read-only cheatpath, `cheat` will
transparently copy that sheet to a writeable directory before opening it for
editing.
### Directory-scoped Cheatpaths ###
At times, it can be useful to closely associate cheatsheets with a directory on
your filesystem. `cheat` facilitates this by searching for a `.cheat` folder in
the current working directory. If found, the `.cheat` directory will
(temporarily) be added to the cheatpaths.

# ADR-001: Path Traversal Protection for Cheatsheet Names
Date: 2025-01-21
## Status
Accepted
## Context
The `cheat` tool allows users to create, edit, and remove cheatsheets using commands like:
- `cheat --edit <name>`
- `cheat --rm <name>`
Without validation, a user could potentially provide malicious names like:
- `../../../etc/passwd` (directory traversal)
- `/etc/passwd` (absolute path)
- `~/.ssh/authorized_keys` (home directory expansion)
While `cheat` is a local tool run by the user themselves (not a network service), path traversal could still lead to:
1. Accidental file overwrites outside cheatsheet directories
2. Confusion about where files are being created
3. Potential security issues in shared environments
## Decision
We implemented input validation for cheatsheet names to prevent directory traversal attacks. The validation rejects names that:
1. Contain `..` (parent directory references)
2. Are absolute paths (start with `/` on Unix)
3. Start with `~` (home directory expansion)
4. Are empty
5. Start with `.` (hidden files - these are not displayed by cheat)
The validation is performed at the application layer before any file operations occur.
## Implementation Details
### Validation Function
The validation is implemented in `internal/sheet/validate.go`:
```go
func Validate(name string) error {
// Reject empty names
if name == "" {
return fmt.Errorf("cheatsheet name cannot be empty")
}
// Reject names containing directory traversal
if strings.Contains(name, "..") {
return fmt.Errorf("cheatsheet name cannot contain '..'")
}
// Reject absolute paths
if filepath.IsAbs(name) {
return fmt.Errorf("cheatsheet name cannot be an absolute path")
}
// Reject names that start with ~ (home directory expansion)
if strings.HasPrefix(name, "~") {
return fmt.Errorf("cheatsheet name cannot start with '~'")
}
// Reject hidden files (files that start with a dot)
filename := filepath.Base(name)
if strings.HasPrefix(filename, ".") {
return fmt.Errorf("cheatsheet name cannot start with '.' (hidden files are not supported)")
}
return nil
}
```
### Integration Points
The validation is called in:
- `cmd/cheat/cmd_edit.go` - before creating or editing a cheatsheet
- `cmd/cheat/cmd_remove.go` - before removing a cheatsheet
### Allowed Patterns
The following patterns are explicitly allowed:
- Simple names: `docker`, `git`
- Nested paths: `docker/compose`, `lang/go/slice`
- Current directory references: `./mysheet`
## Consequences
### Positive
1. **Safety**: Prevents accidental or intentional file operations outside cheatsheet directories
2. **Simplicity**: Validation happens early, before any file operations
3. **User-friendly**: Clear error messages explain why a name was rejected
4. **Performance**: Minimal overhead - simple string checks
5. **Compatibility**: Doesn't break existing valid cheatsheet names
### Negative
1. **Limitation**: Users cannot use `..` in cheatsheet names even if legitimate
2. **No symlink support**: Cannot create cheatsheets through symlinks outside the cheatpath
### Neutral
1. Uses Go's `filepath.IsAbs()` which handles platform differences (Windows vs Unix)
2. No attempt to resolve or canonicalize paths - validation is purely syntactic
## Security Considerations
### Threat Model
`cheat` is a local command-line tool, not a network service. The primary threats are:
- User error (accidentally overwriting important files)
- Malicious scripts that invoke `cheat` with crafted arguments
- Shared system scenarios where cheatsheets might be shared
### What This Protects Against
- Directory traversal using `../`
- Absolute path access to system files
- Shell expansion of `~` to home directory
- Empty names that might cause unexpected behavior
- Hidden files that wouldn't be displayed anyway
### What This Does NOT Protect Against
- Users with filesystem permissions can still directly edit any file
- Symbolic links within the cheatpath pointing outside
- Race conditions (TOCTOU) - though minimal risk for a local tool
- Malicious content within cheatsheets themselves
## Testing
Comprehensive tests ensure the validation works correctly:
1. **Unit tests** (`internal/sheet/validate_test.go`) verify the validation logic
2. **Integration tests** verify the actual binary blocks malicious inputs
3. **No system files are accessed** during testing - all tests use isolated directories
Example test cases:
```bash
# These are blocked:
cheat --edit "../../../etc/passwd"
cheat --edit "/etc/passwd"
cheat --edit "~/.ssh/config"
cheat --rm ".."
# These are allowed:
cheat --edit "docker"
cheat --edit "docker/compose"
cheat --edit "./local"
```
## Alternative Approaches Considered
1. **Path resolution and verification**: Resolve the final path and check if it's within the cheatpath
- Rejected: More complex, potential race conditions, platform-specific edge cases
2. **Chroot/sandbox**: Run file operations in a restricted environment
- Rejected: Overkill for a local tool, platform compatibility issues
3. **Filename allowlist**: Only allow alphanumeric characters and specific symbols
- Rejected: Too restrictive, would break existing cheatsheets with valid special characters

# ADR-002: No Defensive Checks for Environment Variable Parsing
Date: 2025-01-21
## Status
Accepted
## Context
In `cmd/cheat/main.go` lines 47-52, the code parses environment variables assuming they all contain an equals sign:
```go
for _, e := range os.Environ() {
pair := strings.SplitN(e, "=", 2)
if runtime.GOOS == "windows" {
pair[0] = strings.ToUpper(pair[0])
}
envvars[pair[0]] = pair[1] // Could panic if pair has < 2 elements
}
```
If `os.Environ()` returned a string without an equals sign, `strings.SplitN` would return a slice with only one element, causing a panic when accessing `pair[1]`.
## Decision
We will **not** add defensive checks for this condition. The current code that assumes all environment strings contain "=" will remain unchanged.
## Rationale
### Go Runtime Guarantees
Go's official documentation guarantees that `os.Environ()` returns environment variables in the form "key=value". This is a documented contract of the Go runtime that has been stable since Go 1.0.
### Empirical Evidence
Testing across platforms confirms:
- All environment variables returned by `os.Environ()` contain at least one "="
- Empty environment variables appear as "KEY=" (with an empty value)
- Even Windows special variables like "=C:=C:\path" maintain the format
### Cost-Benefit Analysis
Adding defensive code would:
- **Cost**: Add complexity and cognitive overhead
- **Cost**: Suggest uncertainty about Go's documented behavior
- **Cost**: Create dead code that can never execute under normal conditions
- **Benefit**: Protect against a theoretical scenario that violates Go's guarantees
The only scenarios where this could panic are:
1. A bug in Go's runtime (extremely unlikely, would affect all Go programs)
2. Corrupted OS-level environment (would cause broader system issues)
3. Breaking change in future Go version (would break many programs, unlikely)
## Consequences
### Positive
- Simpler, more readable code
- Trust in platform guarantees reduces unnecessary defensive programming
- No performance overhead from unnecessary checks
### Negative
- Theoretical panic if Go's guarantees are violated
### Neutral
- Follows Go community standards of trusting standard library contracts
## Alternatives Considered
### 1. Add Defensive Check
```go
if len(pair) < 2 {
continue // or pair[1] = ""
}
```
**Rejected**: Adds complexity for a condition that should never occur.
### 2. Add Panic with Clear Message
```go
if len(pair) < 2 {
panic("os.Environ() contract violation: " + e)
}
```
**Rejected**: Would crash the program for the same theoretical issue.
### 3. Add Comment Documenting Assumption
```go
// os.Environ() guarantees "key=value" format, so pair[1] is safe
envvars[pair[0]] = pair[1]
```
**Rejected**: While documentation is good, this particular guarantee is fundamental to Go.
## Notes
If Go ever changes this behavior (extremely unlikely as it would break compatibility), it would be caught immediately in testing as the program would panic on startup. This would be a clear signal to revisit this decision.

# ADR-003: No Parallelization for Search Operations
Date: 2025-01-22
## Status
Accepted
## Context
We investigated optimizing cheat's search performance through parallelization. Initial assumptions suggested that I/O operations (reading multiple cheatsheet files) would be the primary bottleneck, making parallel processing beneficial.
Performance benchmarks were implemented to measure search operations, and a parallel search implementation using goroutines was created and tested.
## Decision
We will **not** implement parallel search. The sequential implementation will remain unchanged.
## Rationale
### Performance Profile Analysis
CPU profiling revealed that search performance is dominated by:
- **Process creation overhead** (~30% in `os/exec.(*Cmd).Run`)
- **System calls** (~30% in `syscall.Syscall6`)
- **Process management** (fork, exec, pipe setup)
The actual search logic (regex matching, file reading) was negligible in the profile, indicating our optimization efforts were targeting the wrong bottleneck.
### Benchmark Results
Parallel implementation showed minimal improvements:
- Simple search: 17ms → 15.3ms (10% improvement)
- Regex search: 15ms → 14.9ms (minimal improvement)
- Colorized search: 19.5ms → 16.8ms (14% improvement)
- Complex regex: 20ms → 15.3ms (24% improvement)
The best case saved only ~5ms in absolute terms.
### Cost-Benefit Analysis
**Costs of parallelization:**
- Added complexity with goroutines, channels, and synchronization
- Increased maintenance burden
- More difficult debugging and testing
- Potential race conditions
**Benefits:**
- 5-15% performance improvement (5ms in real terms)
- Imperceptible to users in interactive use
### User Experience Perspective
For a command-line tool:
- Current 15-20ms response time is excellent
- Users cannot perceive 5ms differences
- Sub-50ms is considered "instant" in HCI research
## Consequences
### Positive
- Simpler, more maintainable codebase
- Easier to debug and reason about
- No synchronization bugs or race conditions
- Focus remains on code clarity
### Negative
- Missed opportunity for ~5ms performance gain
- Search remains single-threaded
### Neutral
- Performance remains excellent for intended use case
- Follows Go philosophy of preferring simplicity
## Alternatives Considered
### 1. Keep Parallel Implementation
**Rejected**: Complexity outweighs negligible performance gains.
### 2. Optimize Process Startup
**Rejected**: Process creation overhead is inherent to CLI tools and cannot be avoided without fundamental architecture changes.
### 3. Future Optimizations
If performance becomes critical, consider:
- **Long-running daemon**: Eliminate process startup overhead entirely
- **Shell function**: Reduce fork/exec overhead
- **Compiled-in cheatsheets**: Eliminate file I/O
However, these would fundamentally change the tool's architecture and usage model.
## Notes
This decision reinforces important principles:
1. Always profile before optimizing
2. Consider the full execution context
3. Measure what matters to users
4. Complexity has a real cost
The parallelization attempt was valuable as a learning exercise and definitively answered whether this optimization path was worthwhile.

# ADR-004: Recursive `.cheat` Directory Search
Date: 2026-02-15
## Status
Accepted
## Context
Previously, `cheat` only checked the current working directory for a `.cheat`
subdirectory to use as a directory-scoped cheatpath. If a user was in
`~/projects/myapp/src/handlers/` but the `.cheat` directory lived at
`~/projects/myapp/.cheat`, it would not be found. Users requested (#602) that
`cheat` walk up the directory hierarchy to find the nearest `.cheat`
directory, mirroring the discovery pattern used by `git` for `.git`
directories.
## Decision
Walk upward from the current working directory to the filesystem root, and
stop at the first `.cheat` directory found. Only directories are matched (a
file named `.cheat` is ignored).
### Stop at first `.cheat` found
Rather than collecting multiple `.cheat` directories from ancestor directories:
- Matches `.git` discovery semantics, which users already understand
- Fits the existing single-cheatpath-named-`"cwd"` code without structural
changes
- Avoids precedence and naming complexity when multiple `.cheat` directories
exist in the ancestor chain
- `cheat` already supports multiple cheatpaths via `conf.yml` for users who
want that; directory-scoped `.cheat` serves the project-context use case
### Walk to filesystem root (not `$HOME`)
Rather than stopping the search at `$HOME`:
- Simpler implementation with no platform-specific home-directory detection
- Supports sysadmins working in `/etc`, `/srv`, `/var`, or other paths
outside `$HOME`
- The boundary only matters on the failure path (no `.cheat` found anywhere),
where the cost is a few extra `stat` calls
- Security is not a concern since cheatsheets are display-only text, not
executable code
## Consequences
### Positive
- Users can place `.cheat` at their project root and it works from any
subdirectory, matching their mental model
- No configuration changes needed; existing `.cheat` directories continue to
work identically
- Minimal code change (one small helper function)
### Negative
- A `.cheat` directory in an unexpected ancestor could be picked up
unintentionally, though this is unlikely in practice and matches how `.git`
works
### Neutral
- The cheatpath name remains `"cwd"` regardless of which ancestor the `.cheat`
was found in
## Alternatives Considered
### 1. Stop at `$HOME`
**Rejected**: Adds platform-specific complexity for minimal benefit. The only
downside of walking to root is a few extra `stat` calls on the failure path.
### 2. Collect multiple `.cheat` directories
**Rejected**: Introduces precedence and naming complexity. Users who want
multiple cheatpaths can configure them in `conf.yml`.

# The paths at which cheatsheets are available. Tags associated with a cheatpath
# are automatically attached to all cheatsheets residing on that path.
#
# Whenever cheatsheets share the same title (like 'tar'), the most local
# cheatsheets (those which come later in this file) take precedent over the
# less local sheets. This allows you to create your own "overides" for
# "upstream" cheatsheets.
#
# But what if you want to view the "upstream" cheatsheets instead of your own?
# Cheatsheets may be filtered via 'cheat -t <tag>' in combination with other
# commands. So, if you want to view the 'tar' cheatsheet that is tagged as
# 'community' rather than your own, you can use: cheat tar -t community
cheatpaths:
# Paths that come earlier are considered to be the most "global", and will
# thus be overridden by more local cheatsheets. That being the case, you
# should probably list community cheatsheets first.
#
# Note that the paths and tags listed below are placeholders. You may freely
# change them to suit your needs.
#
# Community cheatsheets must be installed separately, though you may have
# downloaded them automatically when installing 'cheat'. If not, you may
# download them here:
#
# https://github.com/cheat/cheatsheets
#
# Once downloaded, ensure that 'path' below points to the location at which
# you downloaded the community cheatsheets.
- name: community
path: COMMUNITY_PATH
tags: [ community ]
readonly: true
# If you have personalized cheatsheets, list them last. They will take
# precedence over the more global cheatsheets.
- name: personal
path: PERSONAL_PATH
tags: [ personal ]
readonly: false
# While it requires no configuration here, it's also worth noting that
# 'cheat' will automatically append directories named '.cheat' within the
# current working directory to the 'cheatpath'. This can be very useful if
# you'd like to closely associate cheatsheets with, for example, a directory
# containing source code.
#
# Such "directory-scoped" cheatsheets will be treated as the most "local"
# cheatsheets, and will override less "local" cheatsheets. Likewise,
# directory-scoped cheatsheets will always be editable ('readonly: false').

func GitDir(path string) (bool, error) {
/*
A bit of context is called for here, because this functionality has
previously caused a number of tricky, subtle bugs.
Fundamentally, here we are simply trying to avoid walking over the
contents of the `.git` directory. Doing so potentially makes
hundreds/thousands of needless syscalls, and can noticeably harm
performance on machines with slow disks.
The earliest effort to solve this problem involved simply returning
`fs.SkipDir` when the cheatsheet file path began with `.`, signifying a
hidden directory. This, however, caused two problems:
1. The `.cheat` directory was ignored
2. Cheatsheets installed by `brew` (which were by default installed to
`~/.config/cheat`) were ignored
See: https://github.com/cheat/cheat/issues/690
To remedy this, the exclusion criteria were narrowed, and the search
for a literal `.` was replaced with a search for a literal `.git`.
This, however, broke user installations that stored cheatsheets in
`git` submodules, because such an installation would contain a `.git`
file that pointed to the upstream repository.
See: https://github.com/cheat/cheat/issues/694
The next attempt at solving this was to search for a `.git` literal
string in the cheatsheet file path. If a match was not found, we would
continue to walk the directory, as before.
If a match *was* found, we determined whether `.git` referred to a file
or directory, and would only stop walking the path in the latter case.
This, however, caused crashes if a cheatpath contained a `.gitignore`
file. (Presumably, a crash would likewise occur on the presence of
`.gitattributes`, `.gitmodules`, etc.)
See: https://github.com/cheat/cheat/issues/699
Accounting for all of the above, the next solution was to search not
for `.git`, but `.git/` (including the directory separator), and then
only ceasing to walk the directory on a match.
This, however, also had a bug: searching for `.git/` also matched
directory names that *ended with* `.git`, like `personal.git/`. This
caused cheatsheets stored under such paths to be silently skipped.
See: https://github.com/cheat/cheat/issues/711
The current (and hopefully final) solution requires the path separator
on *both* sides of `.git`, i.e., searching for `/.git/`. This ensures
that `.git` is matched only as a complete path component, not as a
suffix of a directory name.
To summarize, this code must account for the following possibilities:
1. A cheatpath is not a repository
2. A cheatpath is a repository
3. A cheatpath is a repository, and contains a `.git*` file
4. A cheatpath is a submodule
5. A cheatpath is a hidden directory
6. A cheatpath is inside a directory whose name ends with `.git`
Care must be taken to support the above on both Unix and Windows
systems, which have different directory separators and line-endings.
NB: `filepath.Walk` always passes absolute paths to the walk function,
so `.git` will never appear as the first path component. This is what
makes the "separator on both sides" approach safe.
A reasonable smoke-test for ensuring that skipping is being applied
correctly is to run the following command:
make && strace ./dist/cheat -l | wc -l
That check should be run twice: once normally, and once after
commenting out the "skip" check in `sheets.Load`.
The specific line counts don't matter; what matters is that the number
of syscalls should be significantly lower with the skip check enabled.
