Enhance 'build-appimage' script: - add initial comment block and comments for all major steps in the script for the benefit of casual users of the script - 'configure' to build HTML + PDF documentation - do not remove the man pages from the AppDir (will be used by custom AppRun script) - use a bigger icon - use '-g' for appimagetool so it can figure out the 'updateinfo' string on Travis CI - output big fat warning to users who build AppImage in non-"Trusty" environments Add 'AppStream' metadata file This serves to satisfy desktop environments who want to automatically create menu entries, show screenshots and display software descriptions. Note, this file (qpdf.appdata.xml) may need more tweaking since the Freedesktop folks aren't exactly sure themselves how their 'standard' should exactly look like, and they changed their validation tools quite a bit over the recent years in incompatible ways... Extended and enhanced customized AppRun script - Add a '--ai-usage' invokation param to the AppImage which serves as a starting point to explore the other embedded options - Support displaying of manual pages by running AppImage with added parameter '--man ...' - Also include HTML/PDF documentation, READMEs and licenses into AppImage - Support for more parameters: '--list-man', '--list-pdf', '--list-readme', '--list-license', '--list-html', '--list-exe', '--pdf', '--readme', '--license', '--html' and '--show-apprun' - Support 'fix-pdf' and 'zlib-' as sub-commands (not just as symlinks)

# The purpose of this custom AppRun script is to enable symlinking the AppImage and invoking the corresponding
|
|
# binary depending on which symlink name was used to invoke the AppImage.
|
|
#
|
|
# At the same time it also allows to invoke the embedded binaries as 'sub-commands'. This is in the interest of
|
|
# saving users from creating extra symlinks (without preventing others from STILL using such, should they want
|
|
# or need these).
|
|
#
|
|
# It also provides some additional help parameters in order to allow faster familiarization with functionality
|
|
# embedded in this AppImage. For example it support the listing and viewing of embedded manpages, HTML files,
|
|
# PDF files, licenses and READMEs.
|
|
#
|
|
# Note, the AppImage can be renamed to anything what's 'legal' for an executable name under Linux or used via
|
|
# a symlink under any name and it should behave like 'qpdf' is expected to behave. If the symlink name is
|
|
# 'fix-qdf' or 'zlib-flate' it should behave like these...

|
NOTE: The execution of this AppImage is controlled by a custom AppRun script. The state of this
|
|
script is experimental and preliminary. Hence it may not work as expected, or miss some
|
|
functionality. You can hack on this script by unpacking this AppImage into a local sub directory
|
|
[currently named 'squashfs-root'] with this command:
|
|
|
|
$ARGV0 --appimage-extract
|
|
|
|
After you're done with your hacks, repackage the AppImage again with this command:
|
|
|
|
appimagetool [/path/to/]squashfs-root [/path/to/]QPDF-*.AppImage
|
|
|
