# There is a bug in the next line.  $searchParameters != {} will always return true, because {} is creating
# a new hash reference on the fly, and the inequality operater is comparing the memory location of it
# to the memory location of $searchParameters, and they will always be different. 
# This means that the following code will always get executed as long as $nodes is defined.
# I'm leaving it there because it has always been there, and although I'm sure it was originally meant to
# mean %$searchParameters (essentially "is this hash not empty"), I'm afraid to change it.
if ( $nodes && $searchParameters != {} )

下面是我在不同时间放入代码中的一些代码。有些不是严格意义上的评论，但它们是相同的概念。

在一个跨平台项目中，只需要在一个平台上执行一些特殊代码:

//If defined, will include all the Windows-specific code.
#define LOSE

#ifdef LOSE
#include <windows.h> //WIN32. Duh.
#endif

//Stolen from other_project_name.cpp

    //CAUTION: This has a major Bobby Tables risk. Even if a rulebuilder is used, there's still the risk of something getting corrupted in the database itself.
    //Reading text from anywhere and simply slotting it into an SQL statement is a major security risk. (With thanks to xkcd for the name "Bobby Tables".)
    //Requirement: Eliminate one Bobby Tables by changing [redacted] to be not just straight SQL.
[lots more comments that are not as funny]
/*

        /*
        Okay. It's unrecognized. Why is this a fatal error? It's actually very closely akin to the miswart of botched #includes being a fatal. When writing a C/C++
        program, you need your headers, and if you don't have one, chances are there'll be a million cascaded errors; so by making "unable to open asdf.h" a fatal,
        the compiler suppresses all those errors about undefined symbols and potentially misspelled type names.
        */

    //If someone tries to import 'id' as a field name, it won't work. (We already have our own id.) But I think the probability is so low that I can afford to be funny.
    if (!stricmp(ptr,"id")) {warn(0,"Import","","'id' is a reserved word and cannot be used as a column name. (Try 'ego' or 'superego'.)"); return;}

//Need a place to squirrel away SQL statements somewhere
char *uts[1024]; //Unified Temporary Storage. (Why? Because I said so.)
int nuts=0; //What is it that squirrels keep? Ha!
int utsid[sizeof uts/sizeof *uts];

         * NOTE: This sets tilde.action. If a *
         * tilde header does not exist in the *
         * import file (not the _content_, if *
         * the entire column isn't there), it *
         * will duplicate down through all of *
         * the rows. This is fine for ~id, as *
         * that will never be changed; and if *

         * the user only ever imports Adds or *
         * Revises, but never both at once in *

我的很多评论都隐晦地提到了电影或音乐剧，但如果你不了解这部剧，它们就不会那么有趣了。
