#1777 -importScript doesn't work as expected

I've exported some classes, edited them and now I'm trying to patch an swf with them as
mentioned here: /www.free-decompiler.com/flash/issues/1351-replace-pcode-command-line-using-method-name
The result is those classes stay untouched. When I'm trying to import .pcode from gui, it
says "0 scripts imported."
I did:
java -jar ffdec.jar -selectclass Config -format script:pcode -export script ./source
client.swf
java -jar ffdec.jar -importScript client.swf client_patched.swf ./source
Hello,
I digged through the source code and found out:
The importScript Option only accepts files with the .as Extension.
I also looked through the history of the respective source file - it seems it has always
only supported files with the ".as" extension.
The GUI and the CLI use the same function.
Source file:
com.jpexs.decompiler.flash.importers.AS3ScriptImporter
Yes, the "Import script" feature only bulk imports ActionScripts, not a p-codes, it always
did.
However, to replace single AS3 method via commandline, you can use -replace command.
Example:
java -jar ffdec.jar -replace "file.swf" "file_out.swf" mypkg.MyClass inputfile.txt 12345
where 12345 is method body id, mypkg.MyClass is script name.
You can enable display of method body ids in FFDec on Advanced settings / Scripts page
or by adding
-config showMethodBodyId=true
prefix to your commandline export command.
If you want to bulk modify/import many scripts,
I recommend you using for example RABCDasm tool which does pretty good job (and is fast as
hell).
See https://github.com/CyberShadow/RABCDAsm
For AS1/2 you do not need method body id, just proper ScriptName.
One additional note:
for -replace command, current FFDec version (18.4.0) has a bug preventing passing only 3
arguments to the -replace command. You need for example nightly version 2518 or later
where this is fixed.
