Reindent Selection

sauerbach · Jul 29, 2004#12004-07-29T17:51+00:00

I need help understanding Reindent Selection. I don't understand how to set it up, nor am I certain I understand what it does. Or should do.
Can someone explain it in exquisite detail?
Step by step. What configuration options go in the Advanced menu, what configuration option go in the WordFile, what do I do, what should I see in my file as a result.

If you highlight a block of code and run reindent selection the code will be indented based on the settings in the wordfile.

So in C++ code that looks like this:

Code: Select all

TEST_MAIN(void)
{
printf("\nTEST Begin...\n\n");
  }

Would end up looking like this:

Code: Select all

TEST_MAIN(void)
{
  printf("\nTEST Begin...\n\n");
}

Thank you that's helpful.

BUT what settings in the WORDFILE??

In the wordfiles the characters or even whole words, which are the identifier for indentation for the specific language must be defined - see also help of UE about indentation.

Examples:

for language C/C++:

/Indent Strings = "{" ":"
/Unindent Strings = "}"

for pascal:

/Indent Strings = "BEGIN" "CASE" "DO" "ELSE" "THEN"
/Unindent Strings = "END;" "END"

In the Advanced - Configuration - Edit dialog you can specify, if tabs or spaces are used for indenting the text and how many spaces the indentation should be. This can be set differently for different languages respectively file extensions. In this dialog, also the Auto Indent feature can be enabled/disabled, which forces indentation during writing if enabled.

Still not working here.
I have auto indent working and it indents and outdents properly as I type, but I can not get Reindent Selection to do a thing!
Do I select the words that bracket the beginning and the end of the selection to be indented, or only select the lines in the middle that are to be moved?
I tried both and neither seems to do a thing.
In the language I use I type IF. I indent and type lines of code, then I type ENDIF and UE lines up ENDIF with the IF.
But when I type all the lines in col 1, select the code (with or without the IF / ENDIF) nothing happens.
Interestingly, if I indent the entire block 3 spaces and then try it, all the code jumps to column 1.

You have to select all lines from the IF to the ENDIF including the IF and ENDIF line. Example:

Code: Select all

IF condition 1
        code line 1
  code line 2
     code line 3
   IF condition 2
    code line 4
      code line 5
   ENDIF
 code line 6
    code line 7
ENDIF

If all these lines are selected and you use reindent you should get following:

Code: Select all

IF condition 1
   code line 1
   code line 2
   code line 3
   IF condition 2
      code line 4
      code line 5
   ENDIF
   code line 6
   code line 7
ENDIF

Hope this helps and works. I have not tried it with IF and ENDIF as indent and unindent string.

It's normal that everything jumps to column 1. Since only the selection is considered UE thinks it should be aligned to the left most column.

sauerbach · Aug 11, 2004#82004-08-11T14:37+00:00

I made sure that If was in the INDENT line and Endif in UNINDENT line and tried the example and it does nothing at all.

Mofi · Aug 11, 2004#92004-08-11T15:32+00:00

I played a little bit with my example and found out, that it is really not indented correct and also why.

After the indent string IF only white characters are allowed in the same line. And in the line with the the unindent string ENDIF only white characters are allowed before the unindent string.

So this example is the correct one:

Code: Select all

any text IF
        code line 1 
  code line 2 
     code line 3 
   any text IF
    code line 4 
      code line 5 
   ENDIF any text
 code line 6 
    code line 7 
ENDIF any text

Which is reindented to:

Code: Select all

any text IF
   code line 1
   code line 2
   code line 3
   any text IF
      code line 4
      code line 5
   ENDIF any text
   code line 6
   code line 7
ENDIF any text

I wrote to IDM for a long time ago, that the reindent is not working correctly, if there is more than one unindent string in a line. I often use in language C for example }}} in one line to close 3 loops/conditions.

Now I know, that there are more problems with reindention. Who else has found special situations, where the reindent is not working as expected?

For C++, C, and Java code I've found Artistic Style to be a much better reindenter. I setup a macro to run it on the current selection.
http://astyle.sourceforge.net/

Here's my tool setting.

"C:\Program Files\astyle_1.15.3_win32\astyle.exe" --style=ansi --mode=c --convert-tabs --indent=spaces=2 --indent-cases C:\Windows\Temp\Astyle.tmp

Here's the macro that calls the tool.

InsertMode
ColumnModeOff
HexOff
UnixReOff
Copy
NewFile
Paste
SaveAs "C:\Windows\Temp\Astyle.tmp"
CloseFile
RunTool "Astyle Selection"
Open "C:\Windows\Temp\Astyle.tmp"
SelectAll
Copy
CloseFile
Paste

Has anyone tried to do something like this?

Code: Select all

/Indent Strings = "IF ^([A-Z _ 0-9 a-z]+^)"
/Unindent Strings = "END_IF ^([A-Z _ 0-9 a-z]+^)"

I can't get it work, but this could be an error of the ^([A-Z _ 0-9 a-z]+^) syntax

I think it is very strange that it is not allowed to have a character behind the indent string. How many languages force you to add a condition behind the if? Quiet a lott suppose....

Best regards,

Harry.

Regular expressions are not possible for indent and unindent strings. Regular expressions can only be used for the function strings.

All other definitions in the wordfile are simply words, where strcmp() or stricmp() is used. (Except ** word definitions where strncmp() or strnicmp() is used, I guess).

Hi, Mofi, I read this message from you:

I saw in the help that you can set UE to recognise not the LAST chars in a line, but the FIRST ones just by using the command:
/Indent Strings SOL = ...
instead of:
/Indent Strings = ...

In either case my Reintend Selection command does not work, but this is just a note on your message, hope it is useful for everybody.

Thanks mdimdi to add the second indent string definition here.

This could be helpful at some languages, but it is not helpful on my examples. Both are not reindented correct, when /Indent Strings SOL = is used instead of /Indent Strings =.

Harry · Oct 29, 2004#152004-10-29T11:13+00:00

Thanks mdimdi for the suggestion, my problem is solved!

Now I have added this line to my definition file:

/Indent Strings SOL = "DEFINE" "ELSE" "ELSE_IF" "IF" "WHILE"

Best regards,

Harry
