Inskinerator

## Usage

#### Synopsis

     ./inskinerator --base/-b BASE [--override/-o OVERRIDE]
        [--define/-D VAR=VALUE] [--output/-f OUTPUT] \
        [--late-define/-L VAR=VALUE]


#### Options

* **<tt>--base/-b:</tt>** Give the base skin to generate the output
  from.  Can be anything in the `skins/` subdirectory except for:

  * “`common`”, which sits above all skins, containing all of the color
    definitions from Fossil’s `src/default.css` file.

  * “`amber-vt`”, which is an example of an override skin meant to sit
    atop “`default`”; see `--override/o` examples below.

* **<tt>--override/-o</tt>:** Override elements of the `--base` skin
  with files from `skins/OVERRIDE/*.scss`.

* **<tt>--output/-f</tt>:** Write output to the named `OUTPUT` file
  rather than to stdout, as is the default.

* **<tt>--define/-D</tt>:** Define SCSS variables before all
  late-defined variables.  Most useful with values that are used as
  inputs to the definitions in `skins/*/late-vars.scss`.

* **<tt>--late-define/-L</tt>:** Override SCSS variables after
  everything else is computed.  Primarily intended to override single
  skin variables, but may also be used for special purposes with custom
  `--override` skins.



#### <a id="ex-simple"></a> Simple Examples: Adjusting the Default Skin

Rebuild the Fossil default skin’s CSS:

This tool is more useful for creating new variations on the default skin.
For example, you can use `-D` to pass HTML color names to create a
[“fire” themed variant][d2]:

    ./inskinerator -b default \
        -D text-color=lightyellow \
        -D header-color=yellow \
        -D background-color=black \
        -D pri-accent-color=red \
        -D sec-accent-color=darkorange

Note that we don’t necessarily have to override any of the late-defined
colors, as they get the following defaults if not overridden:

| Variable         | Late-Defined Value           |
|------------------|------------------------------|
| title-color      | $pri-accent-color            |
| header-color     | $text-color                  |
| footer-color     | $text-color + 40% lightness  |
| ter-accent-color | inverse of $pri-accent-color |

Or, you can use HTML RGB specs to create this [“PDP-11/70” theme][d3]:

    ./inskinerator -b default \
        -D text-color=\#000 \
        -D header-color=\#B3003B \
        -D title-color=\#622A5A \
        -D pri-accent-color=\#B3003B \
        -D sec-accent-color=\#AE98CD \
        -D ter-accent-color=\#B3003B

Note that `background-color` isn’t needed: we got that from the default
skin.  We can’t do without “black” for the text color, since the default
uses [a very dark gray](/file/skins/default/vars.scss), not black.  But
note also that we pass such strings through as-is, so that HTML’s
allowance for the #000 shortcut works.

You may also mix HTML color names and RGB specs to create this
[mint green variant][d4] of the default skin:

     ./inskinerator -b default \
        -D text-color=\#003300 \
        -D header-color=darkgreen \
        -D title-color=green \
        -D background-color=mintcream \
        -D pri-accent-color=lightseagreen \
        -D sec-accent-color=\#CCFFE6 \
        -D ter-accent-color=darkgreen

[Fizzbuck Light][d5]:

    ./inskinerator -b default \
        -D text-color=black \
        -D pri-accent-color=\#3B579A \
        -D sec-accent-color=lightgray

#### <a id="ex-advanced"></a> Advanced Examples: Applying Skin Overrides

Rather than simply supply overrides for the four key colors as in the
prior section, you can apply entire SCSS files atop the default skin to
provide more drastic adjustments.  This project ships with one such
override: the Amber VT skin from [the PiDP-8/I project][pidp8i].
[Rebuild it][d7] atop the default skin like so:

     ./inskinerator -b default -o amber-vt

You can define `background-pattern` as any CSS color function to
override the default solid background set via via `background-color`,
producing the [Green Bar VT][d8] skin:

     ./inskinerator -b default -o amber-vt \
        -D background-color=\#B8F0A8 \
        -D background-pattern='repeating-linear-gradient(#EEFAEB, #EEFAEB 50px, white 0px, white 100px)' \
        -D vt-text-color=lime

The key color in the Amber VT skins is `background-color`: from that is
derived the color of the page title, the color of the body headers, the
color of the main menu bar, and even the color of the body text.  The
only way to override them is with `-L`, because of the way this skin
overrides the Fossil default skin it’s based on.

You must not only provide `--background-color` for that reason but also
because SCSS isn’t smart enough to derive solid colors from a gradient:
providing `background-pattern` isn’t enough.

We can now come full circle and create a [Paper White VT][d9] skin with
a color scheme reminiscent of the default Fossil skin but with all the
features of the Amber VT skin:

    ./inskinerator -b default -o amber-vt \
        -D background-color=white \
        -D vt-background-color=#333 \
        -D vt-bezel-color=darkgray \
        -D vt-text-color=#EEE \
        -L header-color=#444 \
        -L pri-accent-color=#4082C4 \
        -L ter-accent-color=#4082C4 \
        -L text-color=#444 \
        -L title-color=#4082C4

#### <a id="pmodel"></a> Processing Model

The tool combines files from `skins/*` indirectly named on the command
line with the `--base` and `--override` options with files from
`skins/common/*.scss` and variable overrides via `--define` options to
produce its output. The order of operations is fixed so that the
resulting CSS rules cascade as expected:

``` pikchr indent
CV: box "common vars" "(early)"
    arrow 50%
    box dotted "base vars" "(early)"
    arrow same
    box dotted "override vars" "(if available)"
    arrow same
    box dotted "--define vars" "(if any)"


    arrow same
LV: box dotted "late vars"

CC: box "common" "CSS" at 0.8 below CV
    arrow 50%
    box "base" "CSS"
    arrow same
    box dotted "override" "CSS"
    arrow same
OP: box dotted "override" "Prism.js"

BM: box dotted "base" "@media" at 0.8 below CC
    arrow 50%
OM: box dotted "override" "@media"

arrow right 0.2 from LV.e \






    then down 0.4 \
    then left to CC.w-(0.2,-0.4) \
    then down to 0.2 left of CC.w \
    then to CC.w radius 0.1

arrow right 0.2 from OP.e \
    then down 0.4 \
    then left to BM.w-(0.2,-0.4) \
    then down to 0.2 left of BM.w \
    then to BM.w radius 0.1
```

That is, Inskinerator:

1.  Concatenates the “early” SCSS variables from up to 4 different
    sources in order of most generic to most specific to the output skin,
    then it appends the “late” variables in the same order: common + base
    \+ override + `--define-late`.


    This ordering allows the base and override skins’ late-defined
    variables to use your early-defined variables (`--define/-D`) in
    functions that derive other variables, so you only have to provide a
    small number of inputs to drive an entire skin’s definition.

    You will usually not need `-L` at all; prefer `-D`.  The primary use
    for `-L` is when you wish to override a single variable’s value at
    the end of the process, rather than override inputs to the

    calculations that produce *other* variables.

2.  Concatenates the specified `css.scss` files in a predictable order.
    If you’re using an `--override` skin, you have the option to include
    a `prism.scss` file to add output from Prism.js’s skin generator from
    a separate file, which can therefore be more easily maintained than
    if you mixed it with your main rules in `skins/OVERRIDE/css.scss`.

3.  Appends the specified `media.scss` files in a predictable order. This
    split of main CSS from `@media` CSS allows the latter to override all
    prior main CSS rules by collecting all `@media` rules near the end of
    the file.


## <a id="making"></a> Making New Skins

The core rule is to apply either `--define` rules via the command line
or to write your changes into an `--override` skin file.  Do not
modify anything in the stock files shipped in `skins/*`, particularly
under the `common` or `default` subdirectories.

The file `skins/default/css.scss` is purposefully written in a CSS-ish
form of SCSS, using only variable substitutions, no other SCSS features.
This facilitates merging upstream diffs from `skins/default/css.txt`
into our version of the file.  Similarly, our `skins/common/css.scss` is
largely just a subset of the upstream `src/default.css` file containing
the base skin color rules.

We point this out because there is no especially good reason to do this
in an override skin.  See `skins/amber-vt/css.scss` for ideas of SCSS
features you can take advantage of to simplify the file.

# message, then die.

sub usage {
    my ($error) = @_;
    print "ERROR: $error!\n\n" if defined $error;
    print <<USAGE;
usage: inskinerator --base/-b BASE [--override/-o OVERRIDE] \
        [--define/-D VAR=VALUE] [--late-define/-L VAR=VALUE] \
        [--output-css OUTPUT] [--output-scss OUTPUT] 

    All skins allow overriding at least these variables:

        -D text-color=COLOR
        -D pri-accent-color=COLOR
        -D sec-accent-color=COLOR
        -D background-color=COLOR

        -D title-color=COLOR
        -D header-color=COLOR
        -D footer-color=COLOR
        -D ter-accent-color=COLOR
        -D background-color-solid=COLOR
        -D background-color-pattern=COLOR

    The final group are late-defined variables, defined by default in
    terms of the first group.  If you don't override them, you get the
    default definitions without duplicating their late definitions.
    Thus, a "complete" variables-only override can be done by redefining
    only variables in the first group.

    VALUEs for COLOR variables are any legal CSS color: 'white',
    '#abcdef', '#888', etc.

    Output goes to stdout unless you give a file name via --output-css.

    The intermediate SCSS may be saved (as for debugging) with
    --output-scss.
