Remove redundant use of chnged column/variable. The SELECT statement already ensures each row has chnged==1, so there is no need to check it repeatedly. check-in: be25d412 user: andygoth tags: trunk

Updates to the Xekri skin to match the changes in the other skins
  • [7211414857] Disable font-inflation on all skins.
  • [72cddddbcc] Change default headers to show menu-bar items that would be available to user "anonymous" even if the current user is not logged in.

Built-in Skins
==============

Each subdirectory under this folder describes a built-in "skin".
There are three files in each subdirectory for the CSS, the header,
and the footer for that skin.

To improve an existing built-in skin, simply edit the appropriate
files and recompile.

To add a new skin:

   1.   Create a new subdirectory under skins/.  (The new directory is
        called "skins/newskin" below but you should use a new original
        name, of course.)

   2.   Add files skins/newskin/css.txt, skins/newskin/header.txt,

        and skins/newskin/footer.txt.  Be sure to "fossil add" these files.

   3.   Go to the src/ directory and rerun "tclsh makemake.tcl".  This
        step rebuilds the various makefiles so that they have dependencies
        on the skin files you just installed.

   4.   Edit the BuiltinSkin[] array near the top of the src/skins.c source
        file so that it describes and references the "newskin" skin.
................................................................................

   5.   Type "make" to rebuild.

Development Hints
-----------------

One way to develop a new skin is to copy the baseline files (css.txt,
footer.txt, and header.txt) into a working directory $WORKDIR then
launch Fossil with a command-line option "--skin $WORKDIR".  Example:

        cp -r skins/default newskin
        fossil ui --skin ./newskin

When the argument to --skin contains one or more '/' characters, the
appropriate skin files are read from disk from the directory specified.
So after launching fossil as shown above, you can edit the newskin/css.txt,
newskin/header.txt, and newskin/footer.txt files using your favorite
text editor, then press Reload on your browser to see immediate results.

Built-in Skins
==============

Each subdirectory under this folder describes a built-in "skin".
There are four files in each subdirectory for the CSS, the "details"
file, the footer, and the header for that skin.

To improve an existing built-in skin, simply edit the appropriate
files and recompile.

To add a new skin:

   1.   Create a new subdirectory under skins/.  (The new directory is
        called "skins/newskin" below but you should use a new original
        name, of course.)

   2.   Add files skins/newskin/css.txt, skins/newskin/details.txt,
        skins/newskin/footer.txt and skins/newskin/header.txt.
        Be sure to "fossil add" these files.

   3.   Go to the src/ directory and rerun "tclsh makemake.tcl".  This
        step rebuilds the various makefiles so that they have dependencies
        on the skin files you just installed.

   4.   Edit the BuiltinSkin[] array near the top of the src/skins.c source
        file so that it describes and references the "newskin" skin.
................................................................................

   5.   Type "make" to rebuild.

        fossil ui --skin ./newskin

appropriate skin files are read from disk from the directory specified.
So after launching fossil as shown above, you can edit the newskin/css.txt,

** COMMAND: clean
** Usage: %fossil clean ?OPTIONS? ?PATH1 ...?
**
** Delete all "extra" files in the source tree.  "Extra" files are
** files that are not officially part of the checkout. This operation
** cannot be undone. If paths are specified, only the directories or
** files specified will be considered for cleaning.

**
** You will be prompted before removing each eligible file unless the
** --force flag is in use or it matches the --clean option.  The
** GLOBPATTERN specified by the "ignore-glob" setting is used if the
** --ignore option is omitted, the same with "clean-glob" and --clean
** as well as "keep-glob" and --keep.  If you are sure you wish to
** remove all "extra" files except the ones specified with --ignore
** and --keep, you can specify the optional -f|--force flag and no
** prompts will be issued.  If a file matches both --keep and --clean,
** --keep takes precedence.
**
** Files and subdirectories whose names begin with "." are
** normally kept.  They are handled if the "--dotfiles" option
** is used.
**
** Options:
**    --allckouts      Check for empty directories within any checkouts
**                     that may be nested within the current one.  This
**                     option should be used with great care because the
**                     empty-dirs setting (and other applicable settings)
**                     belonging to the other repositories, if any, will
................................................................................
**                     explicitly exempted via the empty-dirs setting
**                     or another applicable setting or command line
**                     argument.  Matching files, if any, are removed
**                     prior to checking for any empty directories;
**                     therefore, directories that contain only files
**                     that were removed will be removed as well.
**    -f|--force       Remove files without prompting.
**    --verily         Shorthand for: -f --emptydirs --dotfiles


**    --clean <CSG>    Never prompt for files matching this
**                     comma separated list of glob patterns.
**    --ignore <CSG>   Ignore files matching patterns from the
**                     comma separated list of glob patterns.
**    --keep <CSG>     Keep files matching this comma separated
**                     list of glob patterns.
**    -n|--dry-run     If given, display instead of run actions.

**    --temp           Remove only Fossil-generated temporary files.
**    -v|--verbose     Show all files as they are removed.

** COMMAND: clean
** Usage: %fossil clean ?OPTIONS? ?PATH ...?
**
** Delete all "extra" files in the source tree.  "Extra" files are
** files that are not officially part of the checkout. This operation
** cannot be undone. If one or more PATH arguments appear, then only
** the files named, or files contained with directories named, will be
** removed.
**

** Prompted are issued to confirm the removal of each file, unless
** the --force flag is used or unless the file matches glob pattern
** specified by the --clean option.  No file that matches glob patterns
** specified by --ignore or --keep will ever be deleted. The default
** values for --clean, --ignore, and --keep are determined by the
** (versionable) clean-glob, ignore-glob, and keep-glob settings.
** Files and subdirectories whose names begin with "." are automatically
** ignored unless the --dotfiles option is used.
**
** The --verily option ignores the keep-glob and ignore-glob settings
** and turns on --force, --dotfiles, and --emptydirs.  Use the --verily
** option when you really want to clean up everything.
**
** Options:
**    --allckouts      Check for empty directories within any checkouts
**                     that may be nested within the current one.  This
**                     option should be used with great care because the
**                     empty-dirs setting (and other applicable settings)
**                     belonging to the other repositories, if any, will
................................................................................
**                     explicitly exempted via the empty-dirs setting
**                     or another applicable setting or command line
**                     argument.  Matching files, if any, are removed
**                     prior to checking for any empty directories;
**                     therefore, directories that contain only files
**                     that were removed will be removed as well.
**    -f|--force       Remove files without prompting.
**    -x|--verily      Remove everything that is not a managed file or
**                     the repository itself.  Implies -f --emptydirs
**                     --dotfiles.  Disregard keep-glob and ignore-glob.
**    --clean <CSG>    Never prompt for files matching this
**                     comma separated list of glob patterns.
**    --ignore <CSG>   Ignore files matching patterns from the
**                     comma separated list of glob patterns.
**    --keep <CSG>     Keep files matching this comma separated
**                     list of glob patterns.
**    -n|--dry-run     Delete nothing, but display what would have been
**                     deleted.
**    --temp           Remove only Fossil-generated temporary files.
**    -v|--verbose     Show all files as they are removed.
