I've released a little one-module utility, Scriptlike, to help
simplify writing shell script-like programs in D:
It looks like you've covered a lot of the short comings for doing
some cmdln scripting. It also sounds like it would fit right into
what I was doing (I hand only covered the user input portion)
https://github.com/JesseKPhillips/JPDLibs/tree/cmdln (I really
probably should move it into its own project, maybe I should
instead submit mine to yours? Though I use Boost License).
[OT] I also want to thank those behind std.process, std.path, and
std.algorithms these things have been really awesome and I use
heavily (great improvements).
- A thin wrapper over std.path and std.file that provides a
dedicated Path type specifically designed for managing file
paths in a simple, reliable, cross-platform way. No more
dealing with slashes, paths-with-spaces, calling buildPath,
normalizing, or getting paths mixed up with ordinary strings.
Personally I've found the new std.path makes this much easier,
I'm not user how you can address paths-with-spaces as this
depends on who you call, internally I don't need to worry. But
maybe this simplifies it more and is still worth it.
- Optionally enable automatic command echoing (including shell
commands, changing/creating directories and
deleting/copying/moving/linking/renaming both directories and
files) by setting one simple flag: bool scriptlikeTraceCommands
Command echoing, and dry run are both valuable.
- Most typical Phobos modules automatically imported. Who needs
rows and rows of standard lib imports for a mere script?
- Less-pedantic filesystem operations for when you don't care
whether it exists or not: existsAsFile, existsAsDir,
existsAsSymlink, tryRename, trySymlink, tryCopy, tryMkdir,
tryMkdirRecurse, tryRmdir, tryRmdirRecurse, tryRemove: All
check whether the source path exists and return WITHOUT
throwing if there's nothing to do.
This is my biggest gripe with the current available functions!
- One simple call, runShell, to run a shell command
script-style (ie, synchronously with forwarded stdout/in/err)
from any working directory. (Also automatically works around
DMD #10863 without waiting for v2.066 - BTW, thanks all
involved who fixed that.)
Aside from the bug, I don't understand what this provides over
- One simple function, fail(string msg), to help you exit with
an error message in an exception-safe way. (Does require some
minor boilerplate added to your main().)
I've just been using exceptions, Fail should take a return code
