05. Standard Library Gap Analysis & Functionality Catalog
1. Inventory of Go's Standard Library (/Users/ahmedmansour/Documents/go/src)
The Go standard library is widely celebrated as the gold standard of language standard libraries: focused, orthogonal, robust, and batteries-included without bloat. Below is the complete functional catalog of Go's packages:
src/
├── I/O & Streams: io, bufio, path, path/filepath, archive/tar, archive/zip, compress/gzip, compress/zlib
├── Concurrency: sync, sync/atomic, context, runtime
├── Networking: net, net/http, net/url, net/mail, net/rpc
├── Cryptography: crypto, crypto/aes, crypto/cipher, crypto/sha256, crypto/tls, crypto/rand, crypto/rsa
├── Operating System: os, os/exec, os/signal, os/user
├── Text & Strings: fmt, strings, bytes, strconv, unicode, regexp, text/template, html/template
├── Serialization: encoding/json, encoding/xml, encoding/csv, encoding/binary, encoding/base64, encoding/hex
├── Time & Clocks: time
├── Math: math, math/rand/v2, math/big, math/bits
├── Collections & Iter: slices, maps, iter, cmp, container/list, container/heap
├── Diagnostics & Tooling: log, log/slog, testing, flag, reflect
└── Database: database/sql, database/sql/driver2. Current Kyna Standard Library Audit
Kyna currently organizes its standard library across 5 CMake modules under library/:
library/core: basic I/O, console logging, process execution, simplehttpGet/fetch, JSON parsing, in-memory API store.library/collections: basic array functional helpers (filter,map,reduce,sort).library/database: PostgreSQL wrapper (db.query,db.execute) via libpq.library/formats: TOML (toml++) and XML (pugixml) codecs.library/text: UTF-8 string functions (textContains,textSlice,textReplace,textSplit).
3. Comprehensive Gap Matrix: Go vs. Kyna
| Domain | Go Standard Library Package | Status in Kyna | Architectural Gap & Impact on Scalability | Priority |
|---|---|---|---|---|
| Streaming I/O | io, bufio | ❌ Missing | Kyna only supports reading/writing whole files at once into memory (readFile/writeFile). Cannot stream gigabyte files, parse chunked HTTP streams, or process pipes. | CRITICAL |
| Time & Clocks | time | ⚠️ Rudimentary | Kyna has only sleep(ms). No Time struct, no Duration, no monotonic clock support, no timers, no tickers, and no timezone parsing. | CRITICAL |
| Concurrency & Locks | sync, sync/atomic | ❌ Missing | No mutexes, read-write locks, wait groups, or atomic operations. Multi-threaded workloads cannot safely synchronize state. | CRITICAL |
| Structured Logging | log/slog | ⚠️ Primitive | Kyna only has unstructured print(), log(), and logColor(). Lacks structured key-value logging (slog.info("user login", "id", 42)) with JSON handlers. | HIGH |
| Cryptography | crypto, crypto/sha256, crypto/rand | ❌ Missing | No cryptographic hashing (SHA-256, SHA-512), no AES encryption, no cryptographically secure random bytes generator (crypto/rand). | HIGH |
| HTTP Server & Client | net/http | ⚠️ Client Only | Kyna has a basic libcurl HTTP client (fetch). It has no HTTP server capabilities (http.ListenAndServe) to build web APIs, microservices, or webhooks. | HIGH |
| Request Context | context | ❌ Missing | No mechanism to pass deadlines, timeouts, or cancellation signals down call chains across network or database requests. | HIGH |
| Filepath Utilities | path/filepath | ⚠️ Partial | Kyna relies on raw string concatenation for filepaths. Lacks cross-platform path joining, extension extraction, and directory tree walking (WalkDir). | MEDIUM |
| Data Encodings | encoding/csv, encoding/base64, encoding/hex | ❌ Missing | Kyna has JSON, TOML, and XML, but lacks Base64, Hex encoding, and CSV parsing. | MEDIUM |
| Generic Collections | slices, maps, iter | ⚠️ Partial | Array helpers exist in collections, but lack binary search, cloning, generic map keys/values extraction, and lazy iterator pipelines (iter.Seq). | MEDIUM |
| Compression & Archives | compress/gzip, archive/zip | ❌ Missing | Cannot read or write .zip archives or .tar.gz compressed streams. | LOW |
| Introspection | reflect | ❌ Missing | Only basic typeOf(val) string name. Cannot dynamically inspect struct fields, tags, or dynamically invoke methods. | LOW |
4. Detailed Specification of Top 5 Primitives to Implement in Kyna
Primitive 1: Universal Streaming I/O (kyna.io)
Model universal streaming contracts after Go's io.Reader and io.Writer:
intf Reader {
read(buffer: ByteArray): int; # Returns bytes read, or -1 on EOF
}
intf Writer {
write(buffer: ByteArray): int; # Returns bytes written
}
intf Closer {
close(): void;
}
# Universal pipeline operator
fn copy(dst: Writer, src: Reader): int { ... }- Adapts files, network sockets, HTTP response bodies, and in-memory byte buffers to the same streaming seam.
- Allows reading arbitrarily large files in bounded chunks (e.g. 64KB) without running out of memory.
Primitive 2: High-Precision Time (kyna.time)
Model after Go's time.Time and time.Duration:
class Duration {
public nanoseconds: int;
public fn milliseconds(): float { return self.nanoseconds / 1000000.0; }
public fn seconds(): float { return self.nanoseconds / 1000000000.0; }
}
class Time {
# Stores monotonic nanoseconds + UTC wall clock
public fn now(): Time { ... }
public fn add(d: Duration): Time { ... }
public fn sub(other: Time): Duration { ... }
public fn before(other: Time): bool { ... }
public fn after(other: Time): bool { ... }
public fn format(layout: str): str { ... }
}
fn sleep(d: Duration): void { ... }Primitive 3: Concurrency & Synchronization (kyna.sync)
Introduce thread-safe synchronization primitives wrapping host OS mutexes:
class Mutex {
public fn lock(): void;
public fn unlock(): void;
}
class WaitGroup {
public fn add(delta: int): void;
public fn done(): void;
public fn wait(): void;
}Primitive 4: Cryptography & Hashing (kyna.crypto)
Provide cryptographic utilities implemented via host-linked OpenSSL or CommonCrypto:
fn sha256(data: str | ByteArray): str;
fn sha512(data: str | ByteArray): str;
fn hmacSha256(key: str | ByteArray, data: str | ByteArray): str;
fn randomBytes(count: int): ByteArray;Primitive 5: Structured Logging (kyna.log / slog)
Upgrade Kyna's logging to structured JSON output for production environments:
slog.info("Processing order", {
"order_id": 1042,
"user": "ahmed",
"amount": 250.75
});
# Outputs: {"time":"2026-09-02T20:45:00Z","level":"INFO","msg":"Processing order","order_id":1042,"user":"ahmed","amount":250.75}Source captured: 2026-10-11
