feat(cli): enhance CLI flexibility and fix option precedence
- Exposed library configuration options (delimiter, case mode, strictness, etc.) as CLI flags in `cli/main.go`. - Regenerated CLI command implementations using `gosubc` to support the new flags. - Refactored `strings2` helper functions (`ToCamel`, `ToSnake`, etc.) in `permutations.go` and `types.go` to apply default options before user options, allowing users to override defaults. - Updated `process` function in `cli/main.go` to pass parsed options to `strings2` functions as variadic arguments. - Added a section to `README.md` about the CLI mode, demonstrating flag usage. - Added a TODO to `README.md` to support slices for flags when `gosubc` supports it. - Removed accidentally committed `.diff` and `.orig` files.

strings2 provides utilities for converting slices of words into various casing conventions. It is intended to supplement Go's standard library `strings` package with helpers for creating formats such as `camelCase`, `PascalCase`, `snake_case` and `kebab-case`.
10+
11+
## Installation
12+
13+
```
14+
go get github.com/arran4/strings2
15+
```
16+
17+
Add the module to your project and import it:
18+
19+
```go
20+
import "github.com/arran4/strings2"
21+
```
22+
23+
## Usage
24+
25+
Words must implement `fmt.Stringer`. The package defines several helper types which satisfy this interface:
26+
27+
```go
28+
words := []strings2.Word{
29+
strings2.SingleCaseWord("hello"),
30+
strings2.SingleCaseWord("world"),
31+
}
32+
```
33+
34+
### Parsing
35+
36+
The library includes a robust parser to convert strings into typed `Word` objects, distinguishing between acronyms, casing, and delimiters.
37+
38+
```go
39+
// Auto-detect format and parse
40+
words, err := strings2.Parse("helloWorld")
41+
// Result: [SingleCaseWord("hello"), FirstUpperCaseWord("World")]
42+
43+
// Parse specific format
44+
words = strings2.ParseSnakeCase("hello_world")
45+
46+
// Configure parser
47+
words, err = strings2.Parse("N.E.W. World", strings2.ParserSmartAcronyms(true))
48+
```
49+
50+
### Case Conversion Functions
51+
52+
```go
53+
strings2.ToCamelCase(words) // "helloWorld"
54+
strings2.ToPascalCase(words) // "HelloWorld"
55+
strings2.ToKebabCase(words) // "hello-world"
56+
strings2.ToSnakeCase(words) // "hello_world"
57+
```
58+
59+
### Customising Formatting
60+
61+
Behaviour can be tuned with options passed to each function. Some commonly used options include:
62+
63+
- `OptionDelimiter(string)` – change the delimiter used between words.
64+
- `OptionCaseMode(CaseMode)` – set the case transformation mode. Modes include:
65+
- `CMVerbatim`
66+
- `CMFirstTitle`
67+
- `CMAllTitle`
68+
- `CMFirstLower`
69+
- `CMWhispering`
70+
- `CMScreaming`
71+
- `OptionFirstUpper()` – force the result to start with an uppercase letter.
72+
- `OptionFirstLower()` – force the result to start with a lowercase letter.
73+
74+
Examples:
75+
76+
```go
77+
// Custom delimiter
78+
fmt.Println(strings2.ToKebabCase(words, strings2.OptionDelimiter("|")))
79+
80+
// Screaming snake case
81+
fmt.Println(strings2.ToSnakeCase(words, strings2.OptionCaseMode(strings2.CMScreaming)))
82+
```
83+
84+
### CLI Mode
85+
86+
The library also provides a command-line interface that exposes all these options, ensuring that the CLI mode has as much flexibility as the code (without being obligated to use smart defaults).
87+
88+
```bash
89+
strings2 camel "hello world"
90+
# Result: helloWorld
91+
92+
strings2 snake --screaming "hello world"
93+
# Result: HELLO_WORLD
94+
95+
strings2 kebab --first-upper "hello world"
96+
# Result: Hello-world
97+
```
98+
99+
You can pipe input into the CLI as well:
100+
```bash
101+
echo "hello world" | strings2 pascal
102+
# Result: HelloWorld
103+
```
104+
105+
Available flags across commands:
106+
- `--delimiter`, `-d` (string): Override the delimiter
107+
- `--screaming`, `-S`: Enforce uppercase formatting
108+
- `--whispering`, `-w`: Enforce lowercase formatting
109+
- `--first-upper`, `-U`: Capitalize the first letter
110+
- `--first-lower`, `-l`: Lowercase the first letter
111+
- `--mix-case-support`, `-m`: Enable splitting of mixed case words
112+
- `--no-smart-acronyms`: Disable acronym preservation
113+
- `--number-splitting`: Enable letter-digit boundary splitting
114+
115+
# Screaming snake case
116+
strings2 snake --screaming "hello world"
117+
```
118+
119+
Options are composable so multiple behaviours can be applied at once. See the documentation in `types.go` for details on further options.
120+
121+
## TODO
122+
123+
- Support slices for flags when the gosubc version supports it.
