Chimera2

Chimera2 is a very lightweight web browser for X11/Athena. This source is derived from the final development snapshot of Chimera 2.0p19, as well as well as the Debian patches that continued until 2013, both of which can be gotten from Debian jessie's package

Building

Debian lists the following packages as required for building:

  • libjpeg-dev
  • libpng-dev
  • xutils-dev
  • zlib1g-dev
  • libxaw7-dev
  • libxmu-dev
  • libxt-dev
  • libsm-dev
  • libice-dev
  • libxpm-dev
  • libxext-dev
  • libx11-dev

The build system is rather archaic, and is tuned by modifying Common.tmpl and Imakefile. Once you're fine with your modifications (or just want to use the shipped defaults), run

xmkmf -a &&
make

This should give you a binary at chimera/chimera, which appears to be fully self-contained.

To clean up the source tree fully, use

make myclean

Unlike clean and distclean, this also removes the generated Makefiles.

Run-time configuration

Chimera2 uses an x11-style resources file at ~/.chimera/resources, and will not start up unless you define at least html.defaultFont in there. The following is a full list of resources that Chimera2 appears to use and examples of values or ??? in case the usage is unclear and it is not set anywhere in the code.

convert.convertFiles: ~/.chimera_convert:~john/lib/convert:/local/infosys/lib/convert

html.defaultFont: -*-*-*-*-*-*-*-*-*-*-*-*-*-*
html.propFontPattern: -*-lucida-*-*-*-*-*-*-*-*-*-*-iso10646-1
html.fixedFontPattern: -*-fixed-*-*-*-*-*-*-*-*-*-*-iso8859-1
html.leftMargin: 20
html.rightMargin: 20
html.bottomMargin: 20
html.topMargin: 20
html.printHTMLErrors: false
html.textLineSpace: 3
html.tableCellInfinity: 0
html.inlineTimeOut: 5000
html.selectTimeOut: 1000
html.flowDebug: false
html.constraintDebug: false
html.printTags: false
html.cssFile: ~/.chimera/default.css
html.dlIndent: 20

plain.font: -*-lucida-medium-r-normal-sans-17-120-100-100-p-96-iso10646-1

chimera.helpURL: ???
chimera.homeURL: http://example.org
chimera.maxDownloads: 4
chimera.printLoadMessages: false
chimera.printTaskInfo: false
chimera.urlLogFile: ~/debug/chimeraurls.log

cache.directory: ~/.chimera/cache
cache.persist: false
cache.ignoreExpires: false
cache.maxSize: 0
cache.ttl: 0

view.path: /usr/local/bin:/usr/bin:/bin
view.capFiles: ~/.chimera/mailcap:~/.mailcap

bookmark.filename: ~/.chimera/bookmarks.html
bookmark.header: <html><body><h2>Bookmarks</h2><ul>
bookmark.footer: </ul></body></html>

file.autoLoad: index.html

http.userAgent: Chimera/2.0alpha
http.acceptLanguage: fi;q=1,en;q=0.9

ftp.dirheader: <html><body><h2>FTP Directory</h2><ul>
ftp.dirtrailer: </ul></body></html>

mailto.dirheader: <html><body><h2>Mailto</h2><ul>
mailto.dirtrailer: </body></html>
user.email: foobar@example.org
mailto.mailer: /usr/bin/sendmail -t

You'll most likely want to use a simpler configuration than this. A usable default .chimera/resources is

html.defaultFont: -*-*-*-*-*-*-*-*-*-*-*-*-*-*
chimera.homeURL: http://example.org
bookmark.filename: ~/.chimera/bookmarks.html

Known bugs

  • Saving pages will often segfault, even when loading them would work.
  • http:// links that redirect to HTTPS hang with "0 bytes read so far."
  • If current URL has query parameters containing a slash, relative links are mishandled.
  • Some problem with displaying images on 68k.news and Frogfind: investigate further
  • Use-after-free when navigating away from a webpage
