digitalmars.D - Rust's simple download script

The method is simple and transparent. An optional --channel=beta or 
--channel=nightly parameter chooses between a stable release (default), 
beta, or nightly build.

Should we do something similar?

Yeah, piping curl into shell is often criticized. It is convenient, though, so could be provided as an option if enough people show interest. It doesn't have to be run as root, as it can just download and unpack a portable installation (essentially what we have in the zip files). If we do this, it has to be done right (e.g. IIRC putting all code in a function so an interrupted download doesn't run a partial script).

when I suggested this to my newbie friend, she found the PATH problem to be a hassle so I did wrapper scripts. What we could do though is download it locally then give them a "D shell" script to set the PATH up. (Or run it automatically in .bashrc or something, but I kinda prefer making it a local script they can run without changing any shared files)

Not necessarily. At least a separate download gives you a chance to verify the download was completed too. Piping direct into shell could deliver an end-of-file in the middle of a file (e.g. in the case of a network error) which might change the results. Most likely result is a half-finished installation leaving not-working garbage on your system, but it might also run a different command... rm -r /yourfile is what it is supposed to do, but instead you received `rm -r /` <end of file>... oops. With a separate download you can at least verify the whole thing was there before running it.

From sandstorm.io I know the trick to wrap everything into a function and call it in the end. An EOF will result in a syntax error then.

yeah, I guess that combined with https (assuming the user hasn't disabled the annoying ssl checks because they rarely work. seriously, how broken are curl and openssl's install systems for trusted certs? but i digress) But I guess them aren't really too bad, no worse than blindly copy/pasting at least.

Well, you already use D so obviously it works good enough for you. However, there might be a million people out there that would love D, but they don't even give it chance because they don't have the skill or the patience to find out how easy/hard it is install it. Making this extremely obvious and easy can only help.

Yeah, this is exactly what happened to a friend of mine. The install instructions as we have them now are complete garbage. They either tell you nothing or actively mislead you with idiocy like copying files all around the system.

If there is anything I hate Rust devs for, it is the madness being advertised as "simple and nice" starting point. It is so horrible I can't help but suspect intentional diversion intended to harm developer culture. - teaches people `curl X | sh` is fine and normal and not security abomination - completely ignores system package manager (and pollutes the system) - doesn't solve any interesting problems (i.e. switching between compiler versions)

Well, to be fair, a LOT of users blindly copy/paste anyway... But that script is a whopping 1400 lines too. Yikes, I wouldn't run that just because it is too bloody big. At least mine is small enough to get the gist of what it is doing by eyeballing it for a minute.

I've been using dvm, and do like it a lot. But I couple issues: 1. Every time I type dvm use, my path adds another directory. Couldn't you just replace the existing dvm path? 2.

I too use dvm all the time and I wonder, if we could integrate it with dub one day and extend it to cater for LDC and GDC as well. In fact, without dvm life would be a lot harder and I think it's high time it became part of an official D toolchain alongside dub.

We should bundle all the existing tools and maybe create a minimal GUI for it. We have dub, dvm, dscanner etc. If we bundle these apps, we can create a small but powerful toolchain.

The issue is that they (the core developers) don't want Tango in any of the core tools and I don't feel like replacing Tango with Phobos for something that is working perfectly fine as it is. It's even working better, because it doesn't depend on libcurl which has caused a lot of problems. It's not even available by default on Windows. On the other hand. I would like to rewrite DVM from scratch and add support for LDC and GDC as well. That could be an opportunity to remove that dependency on Tango, as long as no new dependencies are added, like libcurl. -- /Jacob Carlborg

I see, but if you're going to rewrite DVM anyway, we might as well start brainstorming now and see what needs to be done, how a possible toolchain integration could / should like and so on. Are there any additional features you or anyone else would like?

I don't use DVM but I do switch compilers fairly easily with: rm /usr/local/dmd/current; ln -s /usr/local/dmd/2.069.0; To install a new compiler I just download the latest .tar.xz and place in /usr/local/dmd/; and then rename "dmd2" directory to version number. Didn't see anyone else post a similar install process. It obviously doesn't have to be installed system wide, I just don't really like installed executables to be writeable by my own user. A bash script based installer for the system I use would be very short and simple.

I also think curl | sh is bad, but the idea to have a quick no-brain "just works" installation is great. One good step would be providing packages for all major distros and providing a wget | pkginstall command which effectively does the same thing: wget DMD.deb && dpkg -i DMD.deb for Debian/Ubuntu For example, newbies to Ubuntu might not even know what dpkg is so they will not know what to do with a .deb file since their world consists of apt-get mostly. Many people also don't know what x86 or x86_AMD64 stand for so yet another doubt in a potential downloaders mind. Could then combine this with OS detection through user-agent on the website and show the user the most likely option and command-line suggestion. Another thing I would do is not show LDC and GDC in the front page but have a "other options" sort of thing. People are afraid to fail and each decision is a potential failure that will scare new people off. The idea is that people that already use D know where to find the other compilers and more importantly what they are, but someone that does not use D might get intimidated by too many choices they don't have the knowledge to make confidently. If in doubt, A/B test it. :)

Unfortunately it's sudo dpkg -i dmd.deb || true sudo apt-get -fy install because dpkg doesn't resolve/install dependencies on it's own and apt-get can't install local packages. It's simpler with rpm based packages. sudo yum localinstall dmd.rpm sudo dnf install dmd.rpm

Yes, such an installer would be helpful and I already wrote it twice. https://github.com/travis-ci/travis-build/blob/master/lib/travis/build/script/d.rb https://github.com/MartinNowak/heroku-buildpack-d/blob/master/bin/compile This would be fairly simple to adopt (choosing a good default install location, e.g. ~/.dlang) and can already install the latest dmd, gdc, ldc, any specific dmd-2.068.2, ldc-0.16.1-alpha1 version, and dub. This does not replace a good package installer, but is great for simply downloading and testing without doing a system wide installation. For the necessary env changes we could adopt something like virtualenv's activate/deactive, i.e. `source ~/.dlang/dmd-2.069.0/activate` to use dmd-2.069.0. And of course we can activate the env after the download. Disclaimer: I did not just volunteer to write the script but I'm glad to help anyone doing so.

Nice effect an installer script that makes working with tarballs a snap, would allows us to easily distribute nightlies. http://forum.dlang.org/post/n1vgtk$161g$1 digitalmars.com

Not sure how much difference that is compared to the other opaque native installers. Also, a 500 LOC bash script is almost as an opaque binary ;)

I assume you actually have libz installed and there's some other problem here?

 Not too surprising given the amount of code, the number of dependencies,
 and the lack of any CI testing.
The issue is that DMD constantly breaks my code. Yes I test the betas, many times the bugs I'm reporting are closed as "won't fix". Every single release of DMD since at least 2.050 broke at least one of my projects. I don't see how any CI testing would help when the code breakage I encounter is not fixed. Anyway, I've updated the dependency and it builds with DMD 2.069.1. The number of dependencies are two. The reason for why I'm still using Tango is the libcurl disaster in Phobos. That has hopefully been fixed now but that means a yet another dependency and which is not installed by default on Windows (perhaps static linking would work).
 I managed to build dvm using dmd-2.067.0 (as indicated by the tango
 dependency).
 Apart from the fact that dvm --help offers weird choices (-t,
 --tango      Installs Tango as the standard library.), dvm install
 --help or dvm --help don't explain how to install a compiler.
The --tango flag is a perfectly reasonable option for a D1 compiler.

 Looking at strace it seems you're trying to parse

Yeah, I've noticed that broke. I haven't had time yet to update the code to use LATEST instead.
 After some trial and error it fails to install the selected compiler
 (and doesn't use the much smaller tar.xz downloads btw).
Is the tar.xz archives something that has been announced? I had no idea about it. BTW, I suspect Phobos can't unpack these files. Which either means resorting to third party libraries, something you seem to dislike. Or shell commands, which are not portable.

Have you installed DVM? As Walter would say, bugs reported to the newsgroup will most likely be forgotten.
 All of the above, plus the ability to install gdc/ldc and verify
 downloaded dmd binaries, are achieved by a ~500LOC bash script.

 Of course downloading and installing dmd used to be a lot more chaotic
 when DVM was originally written. But making installations more
 scriptable is a direct outcome of writing such scripts, which works much

I guess your script only cares about the latest version, making everything a lot easier. The reason I brought it up because DVM already exist (I guess your script did as well), offers other features as well and works on Windows. -- /Jacob Carlborg
