How to batch convert bdsproj to dproj?

Question

We recently upgraded from Delphi 2006 to Delphi 2007, and the project files changed from .bdsproj to .dproj.

My research so far indicates that in order to create the .dproj, an existing project needs to be opened in the D2007 IDE. We have over 400 .bdsproj files so doing this manually is not really practical.

The process I came up with was to open all the projects from the command line using:

find . -name *.bdsproj -exec bds.exe -pDelphi -ns -m "{}" ";"

This isn't ideal because it is quite slow (wait for BDS to load, wait for compile to happen, wait while BDS closes, ...).

Is there an efficient way to convert multiple .bdsproj to .dproj?

Note: The 'find' in the above command line is a UNIX-like find (e.g. MKS or GNU) which searches for files, not the Windows find which searches for text within files.

Answer 1

You can open several projects at once. Even using drag and drop.

• Select 40 projects
• Drag them to the IDE
• Click yes 40 times
• Save all
• close all
• Repeat until finished.

Answer 2

Here is a fancier version of the find solution using PowerShell. It searches for bdsproj files under a specified directory and produces a bdsgroup containing all of the projects.

After the script is run, open the bdsgroup with D2007 to convert the projects to dproj. D2007 also produces a groupproj, which seems to be the D2007 equivalent of bdsgroup.

Hints:

• Run the script with -help to see instructions.
• Start D2007 before opening the bdsgroup, it seems to process the projects quicker.
• You don't need to save the projects, opening them is enough to create the dproj.

Thanks to:

• Ulrich Gerhardt for suggesting the bdsgroup approach.
• dangph for help with the PowerShell script.

Here's the script. It works for me :o)

Param(
    $path = ".",
    $exclude = "",
    [switch]$help
)

Set-PSDebug -Strict
$ErrorActionPreference = 'Stop'

# Ensure path is fully qualified and ends with a path delimiter
$path = Join-Path (Resolve-Path $path) ""

# Output file full name ($path\scriptname.bdsproj)
$outfile = Join-Path $path ([IO.Path]::ChangeExtension($MyInvocation.MyCommand.Name, "bdsgroup"))

# Bdsgroup template
$groupXml = [xml]@"

Maybe you could use a command line similar to your find (and maybe a little Delphi programm) to create a *.bdsgroup file with all projects and open that in D2007.
