Useful units

There are many units that are not specific to web programming included with your freepascal download which you will find useful with Powtils. You can use the below units in desktop or console applications too. We have uploaded these docs into LUFDOC so they are all in one easy to access place, instead of you having to use several different websites to read documentation. The lufind tool works with these below docs too.

FPC Website

You can also see mirrors of the above docs at the freepascal website, however they do not contain any additional LUFDOC notes at the bottom if there are any posted here.

Some Internal Powtils Units

(You do not necessarily need to know about the below units since they are used to power some of the core API. However you may wish to use them for custom work, and we can't make assumptions that you won't find these units useful too!)

zlib_adler (compression related)

native_out (fast writeln)

regexp_tregexpr

socketsext

smartbuff (buffer that grows in chunks)

objbuff (another buffer that grows in chunks)

Notes

Above are unit references or an api reference. Each page contains information on source units included with the Powerful Web Utils package.

To see the general documentation and introduction, see the General Index

Not all the extra units, third party add-ons, or latest features added to SVN have been documented yet.

Wrappers and Extensions

We welcome wrappers and extensions around this API. For many simple and straightforward operations the API can be used directly, but nothing stops one from wrapping the above units into higher level constructs. The API and units are designed to be elegant to use as-is, but also designed to be extensible.
