Hello,

To select your files you can use a filter.
Let me give here some explanation.
In Siren the file filters can be used in different places. The most obvious is the "Filter" combobox in the main window. During a directory (tree) scanning only the files passing the filter are taken into account.
You may have noticed that for the selections, highlights ... a filter can also be used.

For example, if you want to automatically select (checkboxes checked) only the "mp3" files, press Ctrl+S (or menu option Select/Select with a filter), enter "*.mp3" (without the ") and click OK.

But that's not all. The filter schema in Siren is not only the standard DOS one. I've extended it to the unix shell one. The help contains a very small description of this. I think it is adapted to your problem.

You surely already know the DOS '?' and '*' characters symbolizing any character (?) or any string (*)
In Siren this list has been extended with: [-]!
This allows you to specify specific character sets or intervals.

For example, if you want only the mp3 files beginning with 'A' or 'B'.
The corresponding filter can be: [AB]*.mp3
For the mp3 files beginning with 'A' to 'Z' it can be: [A-Z]*.mp3
If you don't want mp3 files beginning with 'A' through 'Z', it can be: [!A-Z]*.mp3

Note that I've not invented this, it is part of the standard unix shell.
It has nothing to do with regular expressions.

Let's come back to your problem:
To select/filter ... only the files with base names ending with at least 4 digits, you can use a filter like:
*[0-9][0-9][0-9][0-9].*

Of course you can use ';' (semicolon) to concatenate different filters: *.mp3;*.txt

I hope that this text will help.

Hello Tommy,

Stefan is right, Siren can only change file names but maybe the "Copy to clipboard" feature can help you.

All depends on the format of the text file you're talking about.
If it is only a simple list of file names:
- Start Siren, choose the directory
- If you want to list the subdirectories too, click on the "Recurse" button or press Ctrl+F5
- Select the files you want to list (Ctrl+A for all)
- Right click on the "Current name" column header
- Choose "Copy selected files data"
- Open a text file editor and paste the clipboard content

Depending on your needs maybe will you have to modify this file a bit.
If you're familiar with regular expressions a text editor supporting them could be very useful.

For a more complex list, ie if you want full path ... etc ...
- Create the needed rename expression
- Do the previous operations on the "Future name" column

I don't know "Autohotkey" but based on Stefan's expertise I am sure it can be extremely helpful.

Best regards

Hello,

I assume there is no underscore in front of "expr3" in the first example (not a typo).
I am not sure to understand the extension problem.

If you work on the file name (%f) an expression like this one should work:
%f("_expr3")("expr3")

The two string deletions are chained:
- on the file name without path, delete all the "_expr3"
- on the resulting string (no "_expr3") delete all the "expr3".

The reverse: %f("expr3")("_expr3")
won't do the job as well. Just after the first deletion as all "expr3" have been deleted, only "_" (underscore) will remain from the "_expr3". The second deletion won't be able do its job.

Best regards

Thanks.

Do not hesitate to share your Siren tricks/expressions in the "How to ..." section.

Hello,

You can use an expression like: %le@%Xdod-%Xdot-c%ncs.%le;%f[2,"@"]

In the "Examples" option of the "?" menu, a similar case is explained: "Rename associated files while renumbering them".

Of course what you need is a bit different but the principle is the same.

If you get
20070726-093747-c.cr2
20070726-093747-c_001.jpg

It's because the extension is not taken into account when "%ncs" is evaluated.
Only the text before it is used.
So, the idea is to temporarily add the extension before "%ncs".

It's done by using sub-expressions (separated by ';').
The first one will add it and make the "computation", the second will delete it.
As we separated the extension from the rest with a '@', the removal is based on the same character.

Hoping this will help.

Best Regards

Hello,

I will suppose that the modification needed consists to remove the content of the last "()".

The "nicest" solution seems to be the regular expression. Here is one based on the same principle as Stefan's one:
%f(s/(.*\().*(\).*)/$1$2/)

If you want to use a "standard" expression, this heavy one should work:
%f("(",".*",-1)(")","*.",-1);%f[1,"*"](1,-1)\(\)%f[3,"*"](2)

It uses sub-expressions (only available since version 2.00).
The idea is near the same as the one explained in an example accessible though Siren's "?" menu.
A '.' is added to the '*' to keep the spaces before and after the "()".

I think the 1.90 can do it. Maybe not the way you expect.

If I summarize your need:
You want to rename your mp3 with: %ma - %mT - %mt.%e
The problem is that if "%mT" is empty you get an unneeded "- " between the artist and the title.

The idea is here to append to "%mT" the string " - " only if it contains something.

This can be done with a regular expression modifier like: %mT(s/(.+)/$1 - /)

Where:
s/ : indicates that what follows is a regular expression modifier
(.+) : search for any non empty character string and make it usable in the replacement part
/ separates the regular expression from the replacement format
$1 - : is the replacement format. $1 refers to the value of "(.+)" and " - " is fixed text
/ finishes the format string

If "%mT" is empty, "(.+)" is not "found" and so not replaced ...

The final expression will look like: %ma - %mT(s/(.+)/$1 - /)%mt.%e

Hoping it will help.

Ok.
I change it, tell me this version is ok for you.

Something near what wrote Stefan:
<siren directory>\siren /P /T /F *.mp3;*.wma /S * /D . /E "%%AT_%%f" /R /Q

/S * : As the filter has done its job you can select all the listed files
/D . or /D <your directory> : This way you can have only one copy of Siren.exe (.ini current directory will be replaced by the one given as parameter)
Parameters have to be enclosed in '"' if they contain spaces or special characters
As the expression is in a "bat" file, the '%' have to be doubled
There must be a space between the parameter "name" and its associated parameter (ie: /F *.mp3)
You already know the other parameters

Hoping it will worth your efforts.
If your final goal is to copy the renamed files to your mp3-player, the upcoming version of Siren should help you.

Why not. I'll think about it.

To sort your files by name length maybe can you use this little "trick":

- Select all the files you want to sort in the list
- Use %f(s/./-/g) as rename expression. This way all characters will be replaced by '-' (dash)
- Click on the "Future name" column header once or twice depending on the sorting order you need.

Hi,

Maybe two other solutions to add to Stefan's ones (thanks ).

%f("."," ",1,4)
You already know %f("."," ") to change every "." with " " (space).
The two "new" parameters: 1 and 4 "tell" to do the replacement from the first "." four times.

The other one can look a bit strange because it uses a regular expression and another method:
%f(s/([a-z])\./$1 /gi)
It will replace all "." following an alphabetic character (from a to z) with a " " (space)

There are surely other ways to achieve it.
All depends on your exact needs.
