更改几何包日志输出的单位

几何包会将其计算的尺寸摘要（以点为单位）输出到日志文件。在处理以厘米（或任何其他单位，我猜）为单位的客户规范时，以这些单位输出会很方便。

在我开始编辑执行此操作的宏的私人副本\Gm@logcontent以使用 printlen 包之前，是否有人这样做过？您是否愿意分享您的代码？

使用这种方法可以达到以下效果：

\documentclass[a4paper]{article}

\usepackage{geometry}

\usepackage{xintexpr}

\makeatletter
% the [2] is for one hundredth of a millimeter which seems precise enough
\def\Gm@showdim#1{* \string#1=\xinttheiexpr [2]#1*635/118407168\relax mm^^J}
\makeatother
\begin{document}
See the log
\end{document}

日志内容如下：

*geometry* driver: auto-detecting
*geometry* detected driver: pdftex
*geometry* verbose mode - [ preamble ] result:
* driver: pdftex
* paper: a4paper
* layout: <same size as paper>
* layoutoffset:(h,v)=(0.0pt,0.0pt)
* modes: 
* h-part:(L,W,R)=(89.62709pt, 418.25368pt, 89.6271pt)
* v-part:(T,H,B)=(101.40665pt, 591.5302pt, 152.11pt)
* \paperwidth=210.00mm
* \paperheight=297.00mm
* \textwidth=147.00mm
* \textheight=207.90mm
* \oddsidemargin=6.10mm
* \evensidemargin=6.10mm
* \topmargin=-2.76mm
* \headheight=4.22mm
* \headsep=8.79mm
* \topskip=3.51mm
* \footskip=10.54mm
* \marginparwidth=20.03mm
* \marginparsep=3.87mm
* \columnsep=3.51mm
* \skip\footins=9.0pt plus 4.0pt minus 2.0pt
* \hoffset=0mm
* \voffset=0mm
* \mag=0.01mm
* \@twocolumnfalse
* \@twosidefalse
* \@mparswitchfalse
* \@reversemarginfalse
* (1in=72.27pt=25.4mm, 1cm=28.453pt)

由于方式不同，某些尺寸仍以 pt 表示\Gm@logcontent。例如，它包含

  * h-part:(L,W,R)=(\Gm@lmargin, \Gm@width, \Gm@rmargin)^^J%
  * v-part:(T,H,B)=(\Gm@tmargin, \Gm@height, \Gm@bmargin)^^J%

您需要按照上述思路对其中两处进行修改。

不包含\printlength在包装内printlen，因为它不可扩展。

\documentclass{article}
\usepackage[verbose]{geometry}
\usepackage{xparse}

\ExplSyntaxOn
\NewDocumentCommand{\setunit}{m}
 {
  \tl_gset:Nn \g_geometry_unit_tl { #1 }
 }
\DeclareExpandableDocumentCommand{\printlength}{m}
 {
  \dim_to_decimal_in_unit:nn { #1 } { 1\g_geometry_unit_tl } \g_geometry_unit_tl
 }
\setunit{pt} % initialize
\ExplSyntaxOff


\makeatletter

\makeatother

\setunit{cm}% use centimeters for logging the dimensions

\begin{document}

\end{document}

这是日志文件中的输出
