tritask-vscodeの区切りジャンプ処理

code:ts

function jumpToSeparator(command: string) {

const editor = getEditor();

const doc = editor.document;

const lineCount = doc.lineCount;

const curPos = CursorPositioner.current();

// 区切り行を自力で探す.

// - Why 自力? -> Symbol を作り込むのは大変だし Jump to Next Symbol 的なコマンドもサポートされてないから.

const lineNumberOfSeparators = [];

const line = doc.lineAt(curLineNumber).text;

if (line.length < LEN_BEFORE_DESCRIPTION) {

continue;

}

continue;

}

lineNumberOfSeparators.push(curLineNumber);

}

if (lineNumberOfSeparators.length == 0) {

return;

}

// up down

// Case1 x o(1)

// -1-

// Case2 o(1) o(2)

// -2-

// Case3 o(2) o(3)

// -3-

// Case4 o(3) x

//

// up(上の区切り)時は下から見ていって最初にヒットした区切りにジャンプ.

// down(下の区切り)時は上から見ていって最初にヒットした区切りにジャンプ.
