REACT:Amending Cuesheet File References

When using REACT to rip to individual tracks you can request all cuesheets to be created, by specifying the following in REACT.ini:

CreateAllCuesheets=1

This will create the following files in the working directory:

• "@albumfile@.[s].cue" (Single WAVE file)
• "@albumfile@.[mg].cue" (Multiple WAVE files with gaps (non-compliant))
• "@albumfile@.[m].cue" (Multiple WAVE files with gaps left out)
• "@albumfile@.[mc].cue" (Multiple WAVE files with corrected gaps)

The multi-file cuesheets will reference the tracks using the filename format set in EAC, which should be "$cdartist$ - $album$ - $track$ - $title$" for standard albums, and specifying a ".wav" extension. However, this is unlikely to be the format that your track files are actually in, which means that the cuesheet will need to be amended in order to be useful.

Below, you will find example code for two solutions, using two different tools. You are recommended to use GSAR for this purpose, as certain special characters, e.g.: the ampersand, if used in your filenames, may cause problems when using SED.

Using GSAR

The additional config code below uses the GNU tool GSAR to parse the cuesheet created by EAC, and create a new cuesheet referencing the correctly-named files. This is achieved in the following way:

1. When the first track is processed the cuesheet will be copied to a new cuesheet file named "$cdartist$ - $album$.cue". Also a batch command to set the right code page is written to a temporary batch file called "update-cuesheet.bat".
2. Every time a track is processed, a GSAR command, to replace that track's filename, is written to the temporary batch file.
3. When the last track is processed, a GSAR command is executed to escape percent (%) characters in the temporary batch file.
4. After that, the temporary batch file is executed, executing a GSAR command for each track.
5. The file "update-cuesheet.bat" is deleted.

Creating the GSAR commands for each track

The following lines need to be added to the code which is run for the format you are using for each track:

SET trackCueFile="$cdartist$ - $album$.cue"
IF NOT EXIST %trackCueFile% (
    COPY "@albumfile@.[mg].cue" %trackCueFile%
    ECHO CHCP 1252 ^| PROMPT>>update-cuesheet.bat
)
ECHO @tools@\GSAR.EXE "-s@basename@.wav" "-r%TrackName%.wv" -o %trackCueFile%>>update-cuesheet.bat

Here it is in the WavPack section:

IF NOT @Wavpack@==1 GOTO end_wavpack_tracks
    IF NOT EXIST %TrackDir_Wavpack% MKDIR %TrackDir_Wavpack%
    PUSHD %TrackDir_Wavpack%
        IF @various@==1 SET VA_tag=-w "album artist=@VA@"
        ECHO ON
        @tools@\wavpack.exe @Opt_Wavpack@ %VA_tag% -w artist="@artist@" -w album="@album@" -w track="@track@/@numtracks@" -w title="@title@" -w year="@year@" -w genre="@genre@" -w comment="@comment@" -w encodedby="%USERNAME%" -w encodersettings="Wavpack @Ver_Wavpack@ @Opt_Wavpack@" "@source@" "%TrackName%.wv"
        @ECHO OFF
        SET trackCueFile="$cdartist$ - $album$.cue"
        IF NOT EXIST %trackCueFile% (
            COPY "@albumfile@.[mg].cue" %trackCueFile%
            ECHO CHCP 1252 ^| PROMPT>>update-cuesheet.bat
        )
        ECHO @tools@\GSAR.EXE "-s@basename@.wav" "-r%TrackName%.wv" -o %trackCueFile%>>update-cuesheet.bat
        IF %have_cover%==1 IF NOT EXIST folder.jpg COPY "@cover@" folder.jpg
        TITLE @track@/@numtracks@ - "@album@"
    POPD
:end_wavpack_tracks

Note that the extension ("wv") will need to be changed depending on the format that you are using. Additionally, if you are using MP3, you will need to use the following line instead, which correctly changes the file type to MP3 from WAVE:

ECHO @tools@\GSAR.EXE "-s@basename@.wav""" WAVE" "-r%TrackName%.mp3""" MP3" -o %trackCueFile%>>update-cuesheet.bat

Also, note that the example uses the "multiple WAVE files with gaps (non-compliant)" cuesheet as its source. This is the cuesheet that most users would require; however you can replace "@albumfile@.[mg].cue" with "@albumfile@.[m].cue" or "@albumfile@.[mc].cue" if you wish.

Executing the batch file

The following lines need to be added to the code which is run for the format you are using at the end of the config:

@tools@\GSAR.EXE -s%% -r%%%% -o update-cuesheet.bat
CALL update-cuesheet.bat
DEL update-cuesheet.bat

Here they are in the WavPack section:

IF @Wavpack@==1 (
    PUSHD %TrackDir_Wavpack%
        IF %add_rg%==1 @tools@\wvgain.exe -a *.wv
        REM COPY /Y "@eaclog@" "EAClog.txt"
        @tools@\GSAR.EXE -s%% -r%%%% -o update-cuesheet.bat
        CALL update-cuesheet.bat
        DEL update-cuesheet.bat
    POPD
)

These two lines are universal, and can be added to any format's section with no need for change.

Requirements

You will need to download the Windows version of GSAR, and put the executable in your REACT tools directory.

Using GSAR to other needs

If you're planning to use the GSAR to other string replacement needs, you must make sure to escape certain characters before running GSAR commands in batch files. The "Amending Cuesheet File References" example only needs the percent (%) and the quote (") character escapes. In addition there is one other character to escape, the colon (:).

• The percent is escaped by replacing it with two percents (% -> %%).
• The colon is escaped by replacing it with two colons (: -> ::).
• The quote is escaped by replacing it with three quotes (" -> """) or ASCII decimal or hex value (" -> :034 (decimal) OR " -> :x22 (hex)).

Examples for all three escapes below.

        string= Test: a "perfect" %100 test
escaped string= Test:: a """perfect:x22 %%100 test

And here's a couple of examples how to escape these characters in batch variables.

(variable %text%)

SET text=%text::=::%
SET text=%text:"=:x22%

Escaping the percent character is more complicated. You can't use previous example to escape it in batch variables. Study how this "Amending Cuesheet File References" guide escapes percent characters. Pay close attention to the following command which is meant to be used in a batch file:

GSAR.EXE -s%% -r%%%% -o update-cuesheet.bat

This command replaces all percent characters with two percent characters in the update-cuesheet.bat file. The -o switch tells GSAR to overwrite the update-cuesheet.bat file.

Using SED

The additional config code below uses the GNU tool SED to parse the cuesheet created by EAC, and create a new cuesheet referencing the correctly-named files. This is achieved in the following way:

1. Every time a track is processed a SED command, to replace that track's filename, is written to a temporary text file called "sedlist.txt".
2. When the last track is processed this file is passed to SED which executes each command on the cuesheet text, and writes the new text to a new cuesheet file named "$cdartist$ - $album$.cue".
3. The file "sedlist.txt" is deleted.

Writing the SED commands for each track

The following line needs to be added to the code which is run for the format you are using for each track:

ECHO s/FILE "@basename@\.wav"/FILE "%TrackName%\.wv"/>>sedlist.txt

Here it is in the WavPack section:

IF NOT @Wavpack@==1 GOTO end_wavpack_tracks
    IF NOT EXIST %TrackDir_Wavpack% MKDIR %TrackDir_Wavpack%
    PUSHD %TrackDir_Wavpack%
        IF @various@==1 SET VA_tag=-w "album artist=@VA@"
        ECHO ON
        @tools@\wavpack.exe @Opt_Wavpack@ %VA_tag% -w artist="@artist@" -w album="@album@" -w track="@track@/@numtracks@" -w title="@title@" -w year="@year@" -w genre="@genre@" -w comment="@comment@" -w encodedby="%USERNAME%" -w encodersettings="Wavpack @Ver_Wavpack@ @Opt_Wavpack@" "@source@" "%TrackName%.wv"
        ECHO s/FILE "@basename@\.wav"/FILE "%TrackName%\.wv"/>>sedlist.txt
        @ECHO OFF
        IF %have_cover%==1 IF NOT EXIST folder.jpg COPY "@cover@" folder.jpg
        TITLE @track@/@numtracks@ - "@album@"
    POPD
:end_wavpack_tracks

Note that the extension ("wv") will need to be changed depending on the format that you are using. Additionally, if you are using MP3, you will need to use the following line instead, which correctly changes the file type to MP3 from WAVE:

ECHO s/FILE "@basename@\.wav" WAVE/FILE "%TrackName%\.mp3" MP3/>>sedlist.txt

Executing SED

The following lines need to be added to the code which is run for the format you are using at the end of the config:

@tools@\SED -f sedlist.txt <"@albumfile@.[mg].cue" >"$cdartist$ - $album$.cue"
DEL sedlist.txt

Here they are in the WavPack section:

IF @Wavpack@==1 (
    PUSHD %TrackDir_Wavpack%
        IF %add_rg%==1 @tools@\wvgain.exe -a *.wv
        REM COPY /Y "@eaclog@" "EAClog.txt"
        @tools@\SED -f sedlist.txt <"@albumfile@.[mg].cue" >"$cdartist$ - $album$.cue"
        DEL sedlist.txt
    POPD
)

These two lines are universal, and can be added to any format's section with no need for change. Note though, that the example uses the "multiple WAVE files with gaps (non-compliant)" cuesheet as its source. This is the cuesheet that most users would require; however you can replace "@albumfile@.[mg].cue" with "@albumfile@.[m].cue" or "@albumfile@.[mc].cue" if you wish.

Requirements

You will need to download the Windows version of SED, including its dependencies ("libintl3.dll" and "libiconv2.dll"), and put all three files in your REACT tools directory.
