One of the great things about Delphi is not only is it written in Delphi (mostly), but it ships with the VCL, RTL, & FMX source code. You can use this source code in lots of different ways, which I’ll cover in a bit, but sometimes it is a matter of finding the source file with the code you want. There are over 2,234 Delphi source files in the source folder, so it can take a while to find the right file if you don’t know where to look. Not to mention the 1,711 C files, and a few thousand other assorted files.
I used to use various GREP and full text searching tools to find the code I was looking for, but then I realized Windows 10 (and earlier versions) has a search function built into it, but you need to make a few configuration changes to use it effectively. So I thought I would outline those for you.
Your source folder is usually located in
C:\Program Files (x86)\Embarcadero\Studio\19.0
but it might be different depending on your installation. I usually Pin it to Quick Access, which makes it easy to access since I find I’m there a lot.
The next thing to do is configure your Indexing Options. This is what makes it quick to search for files you need. You can find Indexing Options in Control Panel, or just runcontrol.exe srchadmin.dll.
There are two steps to get the most out of Windows search for your source code. The first is you need to activate Windows search for the file extensions you want, and the second it to tell it to index your folders.
To add PAS files to indexing click Advanced and go to File Types. You can just type PAS in the list of file types and it will find it for you. You don’t need to add a new extension. PAS files are already listed, but just not indexed by default. Just put a check next to it, and change the “How should this file be indexed?” to “Index Properties and File Contents” that will index all the text contents of the file
By default all your user folders are indexed, but Source is in your Program Files folder, so you need to explicitly add it. From the main Indexing Options window click Modify and from there you can add any folder you want to search.
It takes a while a while to build and update the index after this change. You just gave it 2,000 more files to index. It has to read all the text out of them, which takes a while. Once it is done then just go to your source folder and use the search box to quickly find the code you are looking for.
Another great tool to use, to search by file name is the Everything desktop search engine by Voidtools. The thing I love about using Everything is it searches all the file names on your system quickly. The difference between it and Windows Search is Everything only searches the file names, but it searches all the file names.
I find I usually remember the name of a file, but not exactly where I left it. This makes Everything indispensable for me.
So how useful is it that Delphi, RAD Studio and C++Builder includes all this source code? What all can you do with it?
