deletekeywords を使用して lstlisting からキーワードを削除する方法を教えてください。

カスタム形式の Python コードに使用しようとしていますlstlisting。問題は、一部の単語がキーワードとして認識されてしまうことです。ただし、キーワードとして認識される必要はありません。 コマンドを使用しようとしましたdeletekeywordsが、成功しませんでした。

以下は私の問題を再現した mcve tex ドキュメントです。単語 と はapply、hashキーワードに割り当てられた色である青で表示されます。

ファイルlstlang1.sty(コマンドを使用してkpsewhich lstlang1.sty検索) には、 の Python 言語の定義が含まれていますlistings。キーワードは 2 つのグループで定義されています。

  morekeywords={access, and, break, class, continue, def, del, elif, else,%
    except, exec, finally, for, from, global, if, import, in, is, lambda,%
    not, or, pass, print, raise, return, try, while},%
  % Built-ins
  morekeywords=[2]{abs, all, any, basestring, bin, bool, bytearray,%
    callable, chr, classmethod, cmp, compile, complex, delattr, dict, dir,%
    divmod, enumerate, eval, execfile, file, filter, float, format,%
    frozenset, getattr, globals, hasattr, hash, help, hex, id, input, int,%
    isinstance, issubclass, iter, len, list, locals, long, map, max,%
    memoryview, min, next, object, oct, open, ord, pow, property, range,%
    raw_input, reduce, reload, repr, reversed, round, set, setattr, slice,%
    sorted, staticmethod, str, sum, super, tuple, type, unichr, unicode,%
    vars, xrange, zip, apply, buffer, coerce, intern},%

およびキーワードapplyはhash2 番目のグループにあります。これらを削除するには、以下を使用する必要があります。

deletekeywords=[2]{hash,apply},

そうですね、あなたの問題はわかっていると思います。「deletekeywords」は定義済みのキーワードを削除するものだとお考えですが、実際には「morekeywords」で作成したカスタム リストからキーワードを削除します。

残念ながら、私にとって唯一うまくいくのは、すでにあるものを使用して、Python のカスタム スタイルを最初から定義することです。次に、必要なキーワードを「morekeywords」に手動で追加する必要があります。

\lstdefinestyle{pythoncode}{
language={}, %You shall leave this blank 
tabsize=4,
caption={Python function to split between train and test sets.},
label={lst:code_direct},
literate={~} {$\sim$}{1},
backgroundcolor=\color{white},   
basicstyle=\footnotesize,        
breakatwhitespace=false,     
captionpos=b,
morecomment=[l]{##},   
commentstyle=\color{gray}\textit,  
escapeinside={\%*}{*)},            
  extendedchars=true,
  frame=tb, 
  keepspaces=true,
  keywordstyle=\color{blue}\bfseries,  
  morekeywords={return,def,apply,lambda}, %New keywords
  numbers=left,
  numbersep=5pt,
  numberstyle=\tiny\color{gray}, 
  rulecolor=\color{black},       
  showspaces=false, 
  showstringspaces=false,
  showtabs=false,       
  stepnumber=1, 
  stringstyle=\ttb\color{red},
  tabsize=2,                  
  title=\lstname,             
  columns=fixed,
  emph ={split_train_test_by_id, test_set_check},
  emphstyle=\color{red}}

次に、このスタイルを使用するには、

\begin{lstlisting}[style=pythoncode]
 **Your Python Code here**
\end{lstlisting}

おそらく最善ではないでしょうが、誰かがもっと良い答えを出すまでの間はこれで十分でしょう。
