copyself
A small Windows VPC utility used by viperc --build-self.
Build
viperc --project ViperC\copyself\project.vpj --clean
Output: ViperC\copyself\__vpcbuild__\output\copyself.exe.
Usage
copyself <seconds> <source> <destination>
- Waits
<seconds>seconds, then copies<source>to<destination>. - Existing destination is removed first: files are deleted, directories are removed recursively.
- Source file, destination file: deletes the destination file, then copies the source file.
- Source directory, destination directory: removes the destination directory, recreates it, then copies the source directory contents.
- Source file + destination directory, or source directory + destination file: reports an error and does not copy.
- Missing destination directories are created.
- File operation failures print the path and the Win32 error code.
- Source and destination must not be the same path; a destination inside the source directory is rejected.
- A source directory inside the destination directory is rejected because the destination is removed first.
Example
cd ViperC\copyself\__vpcbuild__\output
copyself.exe 5 ../../../__vpcbuild_2__ ../../../__vpcbuild__
Used by viperc --build-self
viperc --build-self locates the ViperC tree from viperc.exe's own path (not from the current working directory), compiles ViperC into ViperC\__vpcbuild_2__, then launches:
copyself.exe 5 ../../__vpcbuild_2__ ../../__vpcbuild__
from working directory ViperC\copyself\output; the executable itself may live in copyself\output or copyself\__vpcbuild__\output. Build copyself.exe first with the command above; --build-self reports the missing executable and the build command if it is absent.
