Complete Examples

In order to illustrate the boxes configuration language described in the previous chapters, we now look at the source code of two complete box designs, one simple and one more complex.

In addition to the examples shown here, please refer to the [official boxes config file](https://github.com/{{ site.github }}/blob/master/boxes-config) for tons more.

Simple Example

Complex Example

BOX tjc

    author   "John Doe <john@doe.com>"
    revision "1.1"
    revdate  "July 16, 1999 (Friday, 18:55h)"
    created  "April 02, 1999 (Friday, 19:26h)"

    Sample
        static char *foo (const int a, const int b)
        /*
         *  Do the foo on the bar and around again.
         *
         *      a     number of doodlefrobs
         *      b     barfoo mode (0 == off)
         *
         *  Memory will be allocated for the result.
         *  Should only be called for lines of length > 0;
         *
         *  RETURNS:  Success: Pointer to result line
         *            Error:   -1   (e.g. frobs depleted)
         *
        * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
         */
        {
            static char temp ....
            int ii;          ....
    ends

    indent "none"                 # alternatives: "box", "text"

    shapes {
        wnw ("/*")
        w   (" *")
        sw  ("* ", " *")
        ssw ("*", "/")
        s   (" *", "  ")
    }

    elastic (s, w)

    delimiter ?"

    replace "\*/" with "*\/"      # quote closing comment tags
    reverse "\*\\/" to "*/"

    padding {
        left 2
        vertical 1
    }

END tjc

Note the SAMPLE block of the latter example. It shows much more than just the box itself, trying to give the user an impression of what the box would look like if used in reality. We only need half the backslashes in the REVERSE and REPLACE statements because we use delimiter to change the escape character from backslash to question mark.
