I am working on an application to search for and build a list of all the times a string (or variable of) is in a text file. Kind of like a Find All function in a text editor that I can build a list with the info that is found, such as
S350
S250
S270
S5000
What can I use to do this search? It will have one value that does not change (The S in this case) followed by up to 4 digits
RegEx seems like a good choice.
Something like.. S(\d{1,4})? might work for you.
Expresso is my preferred regular expression composer.

I want to search all programs - within a package - that use the statement:
modify itab_xyz from wa_itab_xyz
Preferably, the string should be searched with wild cards like itab*
for a range of itab_(values) like itab_abc, itab_def, itab_ghi
etc..
How do i do this in SAP ABAP?
Below is a screenshot of all programs within a package one can search from.
One possibility would be to use program RS_ABAP_SOURCE_SCAN.
You can restrict the selection by package and you can also enter a specific string to search for in the code.
I use the transaction code_scanner (program is afx_code_scanner).
The biggest problem with this program and the RS_ABAP_SOURCE_SCAN provided above is that they won’t find everything. IMO the most important missing component to them is implicit enhancements. They can be very impactful to system functions, and if you are searching for an error message or hard coded value skipping them could mean not finding something critical.
At the time I looked (about 7 years ago), I was unable to find a delivered tool that would actually scan all the code in the system. I ended up enhancing the code_scanner to look for enhancements, WDA components, BSP code, and forms code.
I don’t know if the open source component above includes those. At first glance it doesn’t seem to, but I don’t have time to really dig into it.
You could use a tool from the Galileo-Open Source library. This program searches ABAP Source, OTR-Texts, Message and Textpools for static Text, wildcard patterns or regex patterns.
ABAP-Coding:
https://github.com/galileo-group/galileo-abap-lib/blob/master/%23gal%23devtools_find_text.prog.abap
Textpool:
https://github.com/galileo-group/galileo-abap-lib/blob/master/%23gal%23devtools_find_text.prog.xml
It refers to some additional classes from the library, so you either need to copy these as well or just use ABAPgit to get the whole library. You can also contact me, so I can send you a transport containing the library.
Additional information (October 1, 2020):
I created a version of the report that you can copy/paste to the ABAP editor. It is too long to include it in the response, but you can find it here.
Do not forget to copy the text elements / selection texts.
Required Text Elements:
-----------------------
B00 Scope
B01 Search pattern
H01 Type
H02 Name
H03 Key
H04 Match
Required Selection Texts:
-------------------------
P_CASE Case-sensitive
P_DEVC Package
P_LANGU Language
P_MESS Messages
P_OTR OTR Texts
P_PATT Pattern
P_REGEX Regular expression
P_SOURCE ABAP sources
P_TPOOL Textpools
P_WILDC Wildcard pattern
I have made a process that reads PDFs and scrapes their text in UiPath. I am struggling to come up with a regular expression that I can use to search for a PO Number. The text that comes from the scrape is fairly unstructured so my best bet is to search for a set of numbers that starts with a 'PO' with no space. For example, "PO1234567890". I will be setting a variable so the system knows that no PO number was found if the string doesn't come up with anything. Any reference material would be welcome as I am a beginner to VB. Thanks!
I have researched and cannot find a way to do the type of search I would like to do.
I expect to be able to search for a "PO1234567890" and no let something like "PO" save. So I somehow need to be able to search for "PO - two digits" and any numbers following without whitespace.
Just try the following:
Dim Regex As System.Text.RegularExpressions.Regex
Regex = New System.Text.RegularExpressions.Regex("PO[0-9]+")
Regex.Matches(SearchString)
The regex string PO[0-9]+ means:
PO followed by at least one number
if you want more digits for example 3... just use PO[0-9]{3}[0-9]* that means:
PO followed by three numbers and as numbers as it can match.
If you need help using regex matches just ask.
Hope it helps!
I am working on a Java MVC app, and jdeveloper is the office-mandated IDE that I am using. All I want to do is search for strings (not the data type "string", just a string of characters) that contain underscores (for example, table names or field names like "TABLE_NAME" or "FIELD_NAME"). Unfortunately, it appears that the underscores are not taken into the search (if I search for FIELD_NAME it will return no results, even though I know that the string appears in the code numerous times). Is there a way for me to search for something like FIELD_NAME in this version of jdeveloper?

Like Nick says in the comment, this should just work.
Possibly you have messed with some setting in the Search popup.
Make sure you are searching on the correct file types
Make sure you are searching in the correct Application or project
Be sure to check the option menu at the bottom and set (your) correct settings
I've implemented auto completion to a combobox like this article shows. Is it possible to make it search for substrings instead of just the beginning of the words?
http://www.codeproject.com/Articles/2371/IAutoComplete-and-custom-IEnumString-implementatio
I haven't found any way to customize how IEnumString/IAutoComplete compares the strings. Is it possible?
The built in search options help a bit but it is complete chaos. To find instring matches you need to set flag AcoWordFilter. But this will prevent from numbers being matched!! However, there is a trick to get the numbers to match: preced with a double-quote as in "3 to find a string containing or starting with "3". Some more chaos? In the AcoWordFilter you also need to prefix other characters not considered part of a "word", eg. you need to prefix parentheses with a " but then you will not find parentheses at the first position!
So the solution is either to create your own implementation of IAutoComplete or offer the user to switch between the modes (a bit awkward).
I dont think that the MS engineers are especially proud of such chaos. How about one more option: AcoSearchAnwhere?
After retrieving the Edit control's IAutoComplete interface, query it for an IAutoComplete2 interface. Calling its SetOptions member you can disable prefix filtering by specifying the ACO_NOPREFIXFILTERING AUTOCOMPLETEOPTIONS.
This is available on Windows Vista and later. If you need a solution that works with pre-Vista versions, you'll have to write your own.
I have url, for example:
http://i.myhost.com/myimage.jpg
I want to change this url to
http://i.myhost.com/myimageD.jpg.
(Add D after image name and before point)
i.e I want add some words after image name and before point using regex.
What is the best way do it using regex?
Try using ^(.*)\.([a-zA-Z]{3,5}) and replacing with \1D\2. I'm assuming the extension is 3-5 alphanumeric numbers but you can modify it to suit. E.g. if it's just jpg images then you can put that instead of the [a-zA-Z]{3,5}.
Sounds like a homework question given the solution must use a regex, on that assumption here is an outline to get you going.
If all you have is a URL then #mathematical.coffee's solution will suit. However if you have a chunk of text within which is one or more URLs and you have to locate and change just those then you'll need something a little more involved.
Look at the structure of a URL: {protocol}{address}{item}; where
{protocol} is "http://", "ftp://" etc.;
{address} is a name, e.g. "www.google.com", or a number, e.g. "74.125.237.116" - there will always be at least one dot in the address; and
{item} is "/name" where name is quite flexible - there will be zero or more items, you can think of them as directories and a file but this isn't strictly true. Also the sequence of items can end in a "/" (including when there are zero of them).
To make a regex which matches a URL start by matching each part. In the case of the items you'll want to match the last in the sequence separately - you'll have zero or more "directories" and one "file", the latter must be of the form "name.extension".
Once you have regexes for each part you just concatenate them to produce a regex for the whole. To form the replacement pattern you can surround parts of your regex with parentheses and refer to those parts using \number in the replacement string - see #mathematical.coffee's solution for an example.
The best way to learn regexs is to use an editor which supports them and just experiment. The exact syntax may not be the same as NSRegularExpression but they are mostly pretty similar for the basic stuff and you can translate from one to another easily.
