Automatically format words in a PDFLaTeX document which are in a keyword list

Question

When writing technical documents, I often want to format 'technical phrases' (such as the name of some technology) in a particular way, which becomes annoying when I type the phrases frequently.

I'm wondering if there's a way I could define a list of 'keywords' in my LaTeX document which, when encountered else in the document, are automatically formatted in a particular way (which I would define).

For example, instead of the current method of:

The \textbf{gmond} daemon is the blurst. I hate \textbf{gmond} and \textbf{gmetad}.

I could write something which could look like

\keywords{gmond, gmetad}{\textbf}

The gmond daemon is the blurst. I hate gmond and gmetad.

which would produce identical output as above.

Is this at all possible? I'm happy to have to write \gmond, as long as I don't have to define the command for each word in my keywords list.

Here's a keywordmarkup generator way with expl3 (note: Keywords, not key phrases)

\documentclass{article}

\usepackage{xparse}

\ExplSyntaxOn
\clist_new:N \l_antiearth_keywords_clist

\newcommand{\keywordslist}[2]{%
  \clist_set:Nn \l_antiearth_keywords_clist {#1}
  \clist_map_inline:Nn \l_antiearth_keywords_clist {%
    \expandafter\newcommand\csname ##1\endcsname{{#2 ##1}}
  }
}
\ExplSyntaxOff

\begin{document}
\keywordslist{gmond, gmetad}{\bfseries}

Here is an example with \gmond\ and \gmetad. 

\end{document}

Update

Use different lists (the style handling is not very well yet)

\documentclass{article}

\usepackage{xparse}

\ExplSyntaxOn

\NewDocumentCommand{\keywordslist}{mmm}{%
  \clist_new:c {l_antiearth_#1_clist}
  \clist_set:cn {l_antiearth_#3_clist} {#2}
  \clist_map_inline:cn {l_antiearth_#3_clist} {%
    \expandafter\NewDocumentCommand\csname ##1\endcsname{}{{\csname #3\endcsname ##1}}
  }
}
\ExplSyntaxOff

\begin{document}
\keywordslist{boldlist}{gmond, gmetad}{bfseries}
\keywordslist{italiclist}{other, nope}{itshape}

Here is an example with \gmond\ and \gmetad.

Here is an example with \other\  and \nope.


\end{document}

You can add items to a list and replace the words in the argument to a command. You can add items with

\keywords{comma separated list}{\text…}

where \text… has to be one single command which takes exactly one parameter. The replacement is done with

\applykeywords{text}

Because text is split at the spaces one has to take punctuation into account, see example below.

\documentclass{article}
\usepackage{xparse}

\ExplSyntaxOn

\tl_new:N \g_anti_keywords

\cs_new_protected:Npn \anti_add_keywords:nN #1#2
 {
  \clist_map_inline:nn { #1 }
   {
    \tl_gput_right:Nn \g_anti_keywords {{##1}{#2{##1}}}
   }
 }

\cs_new_protected:Npn \anti_apply_keywords:n #1
 {
  \seq_set_split:Nnn \l_tmpa_seq { ~ } { #1 }
  \seq_map_inline:Nn \l_tmpa_seq
   {
    \str_case:nVF { ##1 } \g_anti_keywords { ##1 } ~
   }
   \tex_unskip:D
 }

\NewDocumentCommand \keywords { m m }
 {
  \anti_add_keywords:nN { #1 } #2
 }

\NewDocumentCommand \applykeywords { m }
 {
  \anti_apply_keywords:n { #1 }
 }

\ExplSyntaxOff

\begin{document}
\keywords{gmond, gmetad}{\textbf}
\keywords{blurst., gmetad.}{\textit}

\applykeywords{The gmond daemon is the blurst. I hate gmond and gmetad.}
\end{document}

Answer 3

\documentclass[12pt,letterpaper,fleqn,parskip=half]{scrartcl}
\usepackage[T1]{fontenc} 
\usepackage[latin1]{inputenc} 
\usepackage{bookman} 
\newcommand{\gm}{\textbf{gmond}}
\newcommand{\gt}{\textbf{gmetad}}

\begin{document}

The \gm\ daemon is the blurst. I hate \gm\ and \gt.

\end{document}

However, and responding to @Anti Earth's just criticism of the above, xelatex (thanks to @jfbu) seems to do this quite well in a minimalist sort of way:

\documentclass {article}
\usepackage {fontspec}
\setmainfont {TeX Gyre Schola} 
\usepackage{soul}
\usepackage{color}
\sethlcolor{yellow}
\usepackage{xesearch}   
\UndoBoundary{-}
\SearchList{phrases}{\hl{#1}}{555-222-1212,Fido,Tinkerbell}
\robustify{\hl}
\SearchList{poems}{\textbf{#1}}{theatre,convention,Timbuktu}
\SearchList{advice}{\textit{#1}{productive,conductive,inductive}

  \begin{document}

    Once upon a time Tinkerbell called the Fairy Princess, at 555-222-1212, to complain that Fido was tinkling on the pretty flowers.
    \bigskip

    Away from the town of Timbuktu

    The theatre of the wise

    And the convention of the poor

    Combined to make the party
    \bigskip

    Your counsel is to only be seen as productive if conductive to proper inductive reasoning.

  \end{document}

which produces:
