多個術語表混合條目：第二個術語表中有重複項

Question

我正在編寫一份包含常數清單和符號清單的報告，兩者都是使用詞彙表包裹。問題是第二個列表（在本例中為常數）不僅包含它應該包含的元素，還包含第一個列表中的元素（符號）：

無論順序為何，都會出現此問題（如果交換順序，符號清單也將包含常數）。我想我必須在列印它們之間調用某種術語表重置命令，但我無法在任何地方找到它。有誰知道是什麼原因導致這個問題？

我使用 Ubuntu 16.04 附帶的 TeXLive-full 發行版。詞彙表包版本根據\listfiles：glossaries.sty 2017/01/19 v4.29

我準備了一個MWE。請注意，我只包含 1 種術語表樣式，而實際上我會對常數和符號清單使用單獨的樣式。這只是為了保持 MWE 較小。單獨的樣式也會出現此問題。這是 main.tex 檔：

\documentclass[12pt,a4paper]{article}

\usepackage{glossaries}

%%%%%%% Load the preamble that contains the glossary styles
\input{./Helpers/glspreamble}

%%%%%%% Define entries for the list of acronyms, constants and symbols
\newglossaryentry{con:g}
{
    type=constants, % entry should be in the list of constants!
    name={\ensuremath{g}}, % Put the symbol here in dollar signs
    description={Local gravitational acceleration}, % A brief description of this entry (to appear in the glossary).
    user1={\ensuremath{9.81}},
    symbol={\ensuremath{\frac{m}{s^2}}}, % put the unit here
    sort=g, % for correct sorting type the full name of the symbol here
    parent=romanletter % for sorting purposes, use romanletter or greekletter
}

\newglossaryentry{sym:t}
{
    type=symbol, % entry should be in the list of symbols!
    name={\ensuremath{t}}, % Put the symbol here in dollar signs
    description={Time}, % A brief description of this entry (to appear in the glossary).
    user1={\ensuremath{-}},
    symbol={\ensuremath{s}}, % put the unit here
    sort=t, % for correct sorting type the full name of the symbol here
    parent=romanletter % for sorting purposes, use romanletter or greekletter
}

\begin{document}

%%%%%%% Print the glossaries
\printnoidxglossary[type=symbol,nonumberlist,style=listoc]

%%%%%%% ----> What should I do here to reset the glossary entries?
\printnoidxglossary[type=constants,nonumberlist,style=listoc]

%%%%%%% Reference an element from every glossary
Reference symbol: \gls{sym:t} \gls{sym:t}\\
Reference constant: \gls{con:g} \gls{con:g}

\end{document}

這是定義詞彙表樣式的 glspreamble.tex 檔案（通常這會包含符號清單的單獨樣式，因為它們沒有值）

Answer 1

您已將一個術語表中的條目指派給另一術語表中的父條目。因此romanletter（在symbol術語表中）在術語表sym:t中有一個子級，在術語表中有symbol一個子級。子項會導致其父項被添加到自己的詞彙表中，但這也會導致父項的所有其他子條目（在本例中）被添加。con:gconstantscon:gromanlettersym:t

我懷疑這其實只是一個錯字，而父級con:g其實應該是romanletterc.

\newglossaryentry{con:g}
{
    type=constants, 
    name={\ensuremath{g}}, 
    description={Local gravitational acceleration},
    user1={\ensuremath{9.81}},
    symbol={\ensuremath{\frac{m}{s^2}}},
    sort=g,
    parent=romanletterc % <--- correction
}

此校正會產生所需的結果。
