Delphi: Search: Regular expression: How to add regular expression 
searching to Delphi? [Systools]

---

Delphi 7 or lower does not have regular expression searching inbuilt.

---

But in Delphi 8, which should be 100% .NET compatible, you could use
the class libraries for regular expression search in your projects
(note: Delphi 7 has a beta .NET compiler available).

---
---

You could use the

 MatchMask()

function for simple regular expressions containing the
? and * metacharacters.

---
---

You could further decide to download a readily available
Delphi library for regular expressions.

---
---

Download Library 'TRegExp' to search your strings:
http://anso.virtualave.net/delphi_stuff.htm#TRegExpr

---
---

An implementation of regular expression searching for Delphi 2 and 
later. The
code is based on that presented by Kernighan & Plauger in their book
"Software Tools in Pascal" (ISBN 0-201-10342-7):

http://www.bsdg.org/swag/DELPHI/0465.PAS.html

---
---

The free downloadable TurboPower 'Systools' library,
which contains also a regular expression library.

---

To download the 'Systools' library:

http://sourceforge.net/projects/tpsystools

---

To get the documentation of 'Systools':

(see systools.pdf, chapter 15 'Regular expressions'):

http://prdownloads.sourceforge.net/tpsystools/tpsystools_docs.zip?
download

---

To install 'Systools' libraries:

unzip, goto Delphi, menu file->open project->change file extension to
package (=.dpk), navigate to directory 'packages', compile all the 4
packages for your Delphi version (e.g. xxxxd70.xxx if you own Delphi
7), click button 'Install'

---

About the 'Systools' regular expression library:

The basic idea is that you have an:

1.input file

2. output file

3. your regular expression which acts on this input file, and produces
   that output file.

---

To use the 'Systools' regular expression library:

goto Delphi, menu file->open project->change file extension to project
(=.dpr), navigate to directory 'examples', then 'Delphi', open one of
the example projects (e.g. 'EXREGEX', for regular expression example).
Before you run it change the path information (menu
'Tools'->'Environment options'->tab 'Library', then add to 'Library
path' and 'Browsing path' the location on your computer of your
'source' directory of Systools (e.g. 'f:\mydownloadfiles\ddd\source;'),
then press button 'OK'). Just ignore some possible error messages for
the moment.
Then compile and run the EXREGEX example. Supply an input filename
(e.g. 'c:\temp\ddd.txt', and output filename (e.g. c:\temp\ddd1.txt').
Click e.g. on button 'Match' and supply a regular expression (e.g.
simply one of the strings which you know is present in the input file.
When clicking button 'Execute', you will then see only that line which
contains that string.)
