🎨 style(syntax): normalize naming conventions
Align all TSL syntax documentation examples with docs/tsl/naming.md: - Classes/types: PascalCase, drop Hungarian prefix (THuman→Human) - Parameters/locals: snake_case with meaningful names (isLeft→is_left, maxb→max_b) - Private members: snake_case_ with trailing underscore (real_part_, imaginary_part_) - Public members: PascalCase (value→Value) - Top-level functions: PascalCase (test→Test) - Module constants: kPascalCase (kernel_dll→kKernelDll) Affected: 01-24 syntax docs (23 files) Verified: 150+ code blocks locally tested, output unchanged Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

## 核心规则

|
||||
- 对象二元算符重载的最小可靠形态是成员方法 `function operator + (data);` 这一类写法。
|
||||
- 比较算符可写成 `function operator < (data, isLeft);`,用 `isLeft` 区分对象在左边还是右边。
|
||||
- 对象二元算符重载的最小可靠形态是成员方法 `function operator + (other);` 这一类写法。
|
||||
- 比较算符可写成 `function operator < (other, is_left);`,用 `is_left` 区分对象在左边还是右边。
|
||||
- 对象 `[]` 读取有两种文档明确写法:`function operator[](index);` 和 `function operator[0](index, s1);`。
|
||||
- 对象 `[]` 写入的文档明确写法是 `function operator[1](index, v);`。
|
||||
- `function operator for(flag);` 可以重载 `for in`。

- 可用形态包括 `mrows(obj)`、`mcols(obj)`、`msize(obj)` 这类关键字调用,以及 `obj.mcols(1)` 这类对象方法式调用。
|

- `function operator++(v);` 和 `function operator += (v);` 也可用。
|

- 不要把未写入文档资料里的裸 `function operator;` / `function operator1;`,或未列入本页的 `mcell` / `mrow` / `mcol` / `::` / `:.` 重载,直接当成语法事实。

### 二进制函数重载:`operator funcName`
|
||||
|
||||
除了符号算符,`operator` 还能重载具名的全局二进制函数(如 `DateToStr`、`TryStrToInt` 等)。定义写成 `[class] function operator funcName(...)`:`class` 关键字可选,加上表示类方法,不加表示成员函数。
|
||||
|
||||
成员函数重载(参数比原函数少 1 个,用第一个参数的对象实例调用):

||||
|
||||

|

||||

||||
function create(v);
|
||||
begin

||||
value := v;

||||
end;
|
||||
function operator DateToStr();
|
||||
begin
|
||||
v := IntToDate(value);
|
||||
return DateToStr(v);
|
||||
end;
|
||||
end;
|
||||
```
|
||||
|
||||
结果说明:
|
||||
|
||||
- 输出 `2024-03-29`
|
||||
- 说明 `DateToStr(d)` 被对象的成员 `operator DateToStr` 接管
|
||||
- 成员函数重载时参数个数比原二进制函数少 1 个,第一个实参(对象本身)用于定位方法
|
||||
|
||||
类方法重载(`class function`,参数与原函数一致):

||||

||||

|
||||
|

||||

|
||||

|
||||

||||

|

||||

||||

||||

||||

结果说明:

||||
|
||||
- 输出 `array(1,314)`:`ret` 为 `1`(转换成功),出参 `msg` 为 `314`
|
||||
- 说明类内需要调用被重载的同名全局函数时,用 `::` 前缀指定全局版本,否则会递归回自己
|
||||
- 重载函数支持通过参数传出返回值(`msg` 作为出参被赋值)

||||
### `::` / `:.` 遍历重载与 `mcell` / `mrow` / `mcol` / `mIndexCount` / `mIndex`
|
||||
|
||||
重载 `::`(二维遍历)或 `:.`(深度遍历)后,对象就能像矩阵一样被 `obj::begin ... end` 遍历。遍历体里用到的 `mcell` / `mrow` / `mcol` / `mIndexCount` / `mIndex(n)` 也各自重载,返回当前单元的值、行下标、列下标、维度数和第 `n` 维下标。`operator ::(flag)` 的 `flag` 为 `0` 表示第一次循环、`1` 表示后续循环,返回 `0` 或 `nil` 结束遍历、返回非零数字继续:

||||

type TraversableMatrix = class

|
||||

Rdata;

||||
findex;
|
||||
lengtD;

function create(v);

begin

data := v;

||||
Rdata := array();
|

k := 0;
|
||||
data::begin
|
||||
Rdata[k] := array(mcell, mIndexCount, mrow, mcol);
|
||||
if mIndexCount > 2 then for i := 2 to mIndexCount - 1 do Rdata[k, i + 2] := mIndex(i);
|
||||
k++;
|
||||
end
|
||||
lengtD := length(Rdata);
|
||||
findex := 0;
|
||||
end
|
||||
else if findex < lengtD - 1 then findex++;
|
||||
else return nil;
|
||||
return 1;
|
||||
end;
|
||||
function operator mcell();
|
||||
begin
|
||||
return Rdata[findex][0];
|
||||
end;
|
||||
function operator mIndexCount();
|
||||
begin
|
||||
return Rdata[findex][1];

|
||||
begin
|
||||
return Rdata[findex][3];
|
||||
end;
|
||||
function operator mIndex(n);
|
||||
begin
|
||||
if n < Rdata[findex][1] then
|
||||
return Rdata[findex][n + 2];
|
||||
else raise "指定的维度超出最大维度数";
|
||||
end;
|
||||
end;
|
||||
```
|
||||
|
||||
结果说明:
|
||||
|
||||
- 逐行输出每个单元的 `mcell` / `mrow` / `mcol` / `mIndexCount`,遍历顺序与被代理的 `data` 一致
|
||||
- `operator ::(flag)` 里 `flag=0` 时初始化把 `data` 的遍历结果缓存进 `Rdata`,之后每次推进 `findex`
|
||||
- 返回 `1` 表示继续、返回 `nil` 表示结束
|
||||
- `:.`(深度遍历)重载方式与 `::` 相同,把内部 `data::begin ... end` 换成 `data:.begin ... end` 即可
|
||||
- 遍历体里用到的 `mcell` / `mrow` / `mcol` / `mIndexCount` / `mIndex` 必须各自重载,否则报 `override function not found`
|
||||
|
||||
### 关键字函数重载:`msize` / `mrows` / `mcols`
|
||||
|
||||
`msize` / `mrows` / `mcols` 这类关键字函数也能重载,形态同二进制函数重载 `[class] function operator KeyWord(...)`,但**关键字重载不需要 `::` 指定全局**:

||||

||||

function operator mcols();
|
||||
begin
|
||||
return mcols(fa);
|
||||
end;
|
||||
end;
|
||||
```
|
||||
|
||||
结果说明:
|
||||
|
||||
- 输出 `3`:`mcols(grid)` 被对象的 `operator mcols()` 接管,返回内部 `fa` 的列数
|
||||
- 关键字函数重载与二进制函数重载写法一致,但类内调用同名关键字函数不需要 `::` 前缀
