commit 02a518774841c893de33e913b5e685aa965f5b0a
Author: Raymond Toy <toy...@gm...>
Date:   Thu Aug 21 13:50:52 2025 -0700

    Run update_examples
    
    This caused the results from `fft` to have the real parts have the
    opposite sign. But this also makes the results match what `fft`
    currently returns and matches what `fftpack5_fft` returns, which is
    nice.

    Add code to compute example for breakup
    
    We can now use update_examples to generate the example for breakup.
    Also run update_examples so we get syntax highlighting when enabled.

    Fix up examples for exponential integrals
    
    For some reason the code for these examples were deleted and we got an
    error.  I've restored the example from the 5.47.0 manual.  (I hope
    that's right.)  Ran update_examples over this example.

    Set intanalysis:false for the intanalysis example
    
    By doing this, we can use update_examples to update this.  This also
    enables syntax highlighting.

    The color scheme isn't so great, but at least the background for the
    pygments highlighting matches the example background.

    Make the background for pygments to match examples
    
    We want to background color for pygments highlighting to match the
    background used for examples.  Otherwise it looks weird.
    
    To do this, define a CSS variable `--example-background-color` that is
    set to the example background color.  Use this variable to set the
    example background and the div highlight class for pygments.

commit 826455014526baf70cb631a3ee0428c68f626300
Author: Raymond Toy <toy...@gm...>
Date:   Thu Aug 21 13:50:52 2025 -0700

    Run update_examples
    
    This caused the results from `fft` to have the real parts have the
    opposite sign. But this also makes the results match what `fft`
    currently returns and matches what `fftpack5_fft` returns, which is
    nice.

commit 8c9ace8bc07668b0c424059b35c6d385620faf0f
Author: Raymond Toy <toy...@gm...>
Date:   Wed Aug 20 21:32:53 2025 -0700

    Add code to compute example for breakup
    
    We can now use update_examples to generate the example for breakup.
    Also run update_examples so we get syntax highlighting when enabled.

    Fix up examples for exponential integrals
    
    For some reason the code for these examples were deleted and we got an
    error.  I've restored the example from the 5.47.0 manual.  (I hope
    that's right.)  Ran update_examples over this example.

    Set intanalysis:false for the intanalysis example
    
    By doing this, we can use update_examples to update this.  This also
    enables syntax highlighting.

    Support dark mode too for pygments
    
    The color scheme isn't so great, but at least the background for the
    pygments highlighting matches the example background.

    Make the background for pygments to match examples
    
    We want to background color for pygments highlighting to match the
    background used for examples.  Otherwise it looks weird.
    
    To do this, define a CSS variable `--example-background-color` that is
    set to the example background color.  Use this variable to set the
    example background and the div highlight class for pygments.

[Maxima-commits] [git] Maxima CAS annotated tag 5.48.1 created. 5.48.1

Version 5.48.1

Dan Gildea (1):
      better fix for text/html index mismatch

Raymond Toy (2):
      Fix mismatch between html and text indices
      Add comments and clean up implementation a little

Viktor T. Toth (1):
      Updating configure.ac with new version number

Wolfgang Dautermann (3):
      Add missing file for crosscompiling to automake.
      Fix replacing \ by / in maxima.bat.in.
      Improve the windows part of commit 06ad96a6.

villate (11):
      Adds missing figure files, removes duplicate names and orders them alphabetically.
      Recomends to also include in Makefile.am the mac file to create the figures.
      Do not add the HTML version of the manual to the distribution tarball. It is not necessary, because those HTML files will be created again when Maxima is compiled and installed. And if the texinfo version of the user is different from the one used by the developer who created the tarball, it might lead to duplication of HTML files with different names. An additional advantage is that the size of the tarball is reduced by 10%.
      Adds the .texi files missing fro the distribution tarball. With this commit the options --enable-lang-de, --enable-lang-ja and --enable-lang-ru now work. However, the links to the figures will be wrong. I still have to figure out how to replace './figures' by '../figures' in all of the non-English HTML pages.
      New version of output_format_for_help: html, that should work in Windows. I have tested it in Linux with several different Lisp flavors and Browsers and it is working as the previous version. The change is to make it work with Windows, which apparently does, but I will only be able to tell for sure tomorrow, after I install the nightly build from Wolfgang's site. A change with respect to the older version is that browser should now be just a string with the name of a browser (can include the complete path). For instance browser: "firefox". It remains to introduce also an encoder for URL's so something such as     file:///Linus Torvals!*/Linux0.0 becomes something such as:     file:///inus%20Torvalds%2A%21/Linux0.0
      Corrects errors the to display help in HTML format in Windows The system command does not need "cmd.exe /c" at the beginning because that is already added in $system (in fact, I added if myself 12 years ago :)). And the definition of $browser is better as Raymond set it originally: "firefox" by default, "start" in Windows, "open" in MacOS or "xdg-open" in Linux.
      This completes my fixes of help output in html for release 5.48.1 System variable browser is now just the name of a web browser. It should work in any operating system. The manual for the section "Help" was updated accordingly, also explaining that decribe can be used to show the results in the manual in Maxima's website. 'output_format_for_help: frontend' now works in Xmaxima.
      Updates the information about Xmaxima's configuration and history files.
      Explains in more detail the process followed by Xmaxima to save its configuration and history.
      Fixes Xmaxima plots in ccl64 for Windows And also improved the way gnuplot plots are produced taking advantage of recent chages in $system.
      Fixes a typo (a forgotten pair of braces).
