I'm making a card game engine on top of libGDX for many similar games I plan to make. Here's how I plan to structure this: each game is a separate project and the engine is a dependency added to the core module. The engine itself will have a lot of assets like card sprites and other UI elements, and they need to be included too.
How can I make that structure work? Is there any way to make a dependency include its assets? The alternative is to duplicate all assets for each game which I don't think is very efficient. Also the assets are in the android module by default, which the engine dependency doesn't have (the engine is a single module). Where do I put the assets in the engine module?
We have a setup that seems similar to what you've outlined above with a "many to one" relationship of projects to assets. Here's a potential way to go about it.
The basic idea is:
Have a single, authoritative assets folder
Have individual projects copy this folder to their build output at build time
Accomplish this by having a project's compile task dependsOn or be finalizedBy a copy task.
Ensure that the Android and other projects are happy by copying the assets to the place that libgdx's internal File APIs look for that particular type of project. (For example, android projects automatically get an assets/ prepended to the URI provided to Gdx.files.internal(). This step is more dependent on your personal file structure, so it may take a little tweaking to get the pathing right for all projects, but don't get discouraged!
Side-note: Gradle should automatically track whether or not the assets dir actually changed. If nothing's been updated, then the copy tasks will effectively become no-ops, which speeds up the build quite a bit for non-first runs. Obviously if you do a cleanAssets like I mention below, then this won't apply.
The advantage of this approach (to me anyway) is that it no longer relies on cross-project links or funky classpath manipulation. It's just real files in real directories. The downside is that it increases the disk space used because there can be multiple physical copies of the assets in the various projects.
The following is not a complete example, but should hopefully give you enough to go by.
Example of a copy task in action. This particular one takes an assets dir from a "core" project and copies it into an android project.
android/build.gradle
task copyAssets(type: Copy) {
from "../core/assets"
into "./assets"
}
Example of how to make the android project's build depend on this task:
android/build.gradle
afterEvaluate { project ->
project.tasks.preDebugBuild {
dependsOn copyAssets
}
project.tasks.preReleaseBuild {
dependsOn cleanAssets
finalizedBy copyAssets
}
}
You'll notice in the preReleaseBuild I added a cleanAssets task as well. It's always a good idea to clean up any junk and do a fresh copy during a production build. cleanAssets is just a basic Delete task.
Example of a copy task dependency for a non-android project:
build {
finalizedBy copyAssets
}
If you're still stuck, let me know where and I'll try to help.
Do it like libgdx does itself. There are assets included in the classpath, like arial-15.fnt which is located in the core project at gdx/src/com/badlogic/gdx/utils/. Take a look at BitmapFont's no-param constructor how it is referenced.
I am converting HTML5 file to .exe using HTML EXECUTABLES converter. After converting to exe, the total size comes around 70 to 80MB. So the problem is when i update a single CSS file I have to convert the whole project again to a exe and give it to my Client and every time i have to upload 80MB file for very small changes.
Is there any other alternate option to update a certain file instead of converting again to exe.
Unless the converter is just creating a zip file with executable archiver: The answer is no.
There are tools however, that let you create a binary path for 2 files, so that you only have to transfer the diff of both. You would however have to create the new EXE and then diff it to the old one for that. So that does not help you too much. Stuff like that is usually done if you handle files in the gigabyte range.
See here for some hints for that: How do I create binary patches?
Or you might try the customer service of your tool, maybe they have an idea: http://www.htmlexe.com/contact
I have a Phonegap project that contains a lot of html-files, javascript files, css-files and images.
When I build the app I want to keep it as small as possible, so I want to exclude all files that are NOT used in the html-files. For example some images in the 'img' directory might not be used in the app.
Somehow I need to make a build-script that searches in every html and css file for other files that are included. Of course the problem is that in each file url's can be relative or absolute.
Is this something that can be automated (maybe with ant?) , or does everybody always pick all necessary files by hand for deployment?
You can use grunt.js
In one word: automation. The less work you have to do when performing
repetitive tasks like minification, compilation, unit testing,
linting, etc, the easier your job becomes.
Basically you can minify and merge all your css in one file as well as all js in one file. At the same time you can exclude files for build process. You can google for example code. I. E.
https://coderwall.com/p/e0jxea or https://github.com/centralway/grunt-phonegap-build (phonegap project grunt based)
It would be nice to have a more or less complete list over what files and/or directories that shouldn't (in most cases) be under source control. What do you think should be excluded?
Suggestion so far:
In general
Config files with sensitive information (passwords, private keys etc.)
Thumbs.db, .DS_Store and desktop.ini
Editor backups: *~ (emacs)
Generated files (for instance DoxyGen output)
C#
bin\*
obj\*
*.exe
Visual Studio
*.suo
*.ncb
*.user
*.aps
*.cachefile
*.backup
_UpgradeReport_Files
Java
*.class
Eclipse
I don't know, and this is what I'm looking for right now :-)
Python
*.pyc
Temporary files
- .*.sw?
- *~
Anything that is generated. Binary, bytecode, code/documents generated from XML.
From my commenters, exclude:
Anything generated by the build, including code documentations (doxygen, javadoc, pydoc, etc.)
But include:
3rd party libraries that you don't have the source for OR don't build.
FWIW, at my work for a very large project, we have the following under ClearCase:
All original code
Qt source AND built debug/release
(Terribly outdated) specs
We do not have built modules for our software. A complete binary is distributed every couple weeks with the latest updates.
OS specific files, generated by their file browsers such as
Thumbs.db and .DS_Store
Some other Visual Studio typical files/folders are
*.cachefile
*.backup
_UpgradeReport_Files
My tortoise global ignore pattern for example looks like this
bin obj *.suo *.user *.cachefile *.backup _UpgradeReport_Files
files that get built should not be checked in
I would approach the problem a different way; what things should be included in source control? You should only source control those files that:
( need revision history OR are created outside of your build but are part of the build, install, or media ) AND
can't be generated by the build process you control AND
are common to all users that build the product (no user config)
The list includes things like:
source files
make, project, and solution files
other build tool configuration files (not user related)
3rd party libraries
pre-built files that go on the media like PDFs & documents
documentation
images, videos, sounds
description files like WSDL, XSL
Sometimes a build output can be a build input. For example, an obfuscation rename file may be an output and an input to keep the same renaming scheme. In this case, use the checked-in file as the build input and put the output in a different file. After the build, check out the input file and copy the output file into it and check it in.
The problem with using an exclusion list is that you will never know all the right exclusions and might end up source controlling something that shouldn't be source controlled.
Like Corey D has said anything that is generated, specifically anything that is generated by the build process and development environment are good candidates. For instance:
Binaries and installers
Bytecode and archives
Documents generated from XML and code
Code generated by templates and code generators
IDE settings files
Backup files generated by your IDE or editor
Some exceptions to the above could be:
Images and video
Third party libraries
Team specific IDE settings files
Take third party libraries, if you need to ship or your build depends on a third party library it wouldn't be unreasonable to put it under source control, especially if you don't have the source. Also consider some source control systems aren't very efficient at storing binary blobs and you probably will not be able to take advantage of the systems diff tools for those files.
Paul also makes a great comment about generated files and you should check out his answer:
Basically, if you can't reasonably
expect a developer to have the exact
version of the exact tool they need,
there is a case for putting the
generated files in version control.
With all that being said ultimately you'll need to consider what you put under source control on a case by case basis. Defining a hard list of what and what not to put under it will only work for some and only probably for so long. And of course the more files you add to source control the longer it will take to update your working copy.
Anything that can be generated by the IDE, build process or binary executable process.
An exception:
4 or 5 different answers have said that generated files should not go under source control. Thats not quite true.
Files generated by specialist tools may belong in source control, especially if particular versions of those tools are necessary.
Examples:
parsers generated by bison/yacc/antlr,
autotools files such as configure or Makefile.in, created by autoconf, automake, libtool etc,
translation or localization files,
files may be generated by expensive tools, and it might be cheaper to only install them on a few machines.
Basically, if you can't reasonably expect a developer to have the exact version of the exact tool they need, there is a case for putting the generated files in version control.
This exception is discussed by the svn guys in their best practices talk.
Temp files from editors.
.*.sw?
*~
etc.
desktop.ini is another windows file I've seen sneak in.
Config files that contain passwords or any other sensitive information.
Actual config files such a web.config in asp.net because people can have different settings. Usually the way I handle this is by having a web.config.template that is on SVN. People get it, make the changes they want and rename it as web.config.
Aside from this and what you said, be careful of sensitive files containing passwords (for instance).
Avoid all the annoying files generated by Windows (thumb) or Mac OS (.ds_store)
*.bak produced by WinMerge.
additionally:
Visual Studio
*.ncb
The best way I've found to think about it is as follows:
Pretend you've got a brand-new, store-bought computer. You install the OS and updates; you install all your development tools including the source control client; you create an empty directory to be the root of your local sources; you do a "get latest" or whatever your source control system calls it to fetch out clean copies of the release you want to build; you then run the build (fetched from source control), and everything builds.
This thought process tells you why certain files have to be in source control: all of those necessary for the build to work on a clean system. This includes .designer.cs files, the outputs of T4 templates, and any other artifact that the build will not create.
Temp files, config for anything other than global development and sensitive information
Things that don't go into source control come in 3 classes
Things totally unrelated to the project (obviously)
Things that can be found on installation media, and are never changed (eg: 3rd-party APIs).
Things that can be mechanically generated, via your build process, from things that are in source control (or from things in class 2).
Whatever the language :
cache files
generally, imported files should not either (like images uploaded by users, on a web application)
temporary files ; even the ones generated by your OS (like thumbs.db under windows) or IDE
config files with passwords ? Depends on who has access to the repository
And for those who don't know about it : svn:ignore is great!
If you have a runtime environment for your code (e.g. dependency libraries, specific compiler versions etc.) do not put the packages into the source control. My approach is brutal, but effective. I commit a makefile, whose role is to downloads (via wget) the stuff, unpack it, and build my runtime environment.
I have a particular .c file that does not go in source control.
The rule is nothing in source control that is generated during the build process.
The only known exception is if a tool requires an older version of itself to build (bootstrap problem). In that case you will need a known good bootstrap copy in source control so you can build from blank.
Going out on a limb here, but I believe that if you use task lists in Visual Studio, they are kept in the .suo file. This may not be a reason to keep them in source control, but it is a reason to keep a backup somewhere, just in case...
A lot of time has passed since this question was asked, and I think a lot of the answers, while relevant, don't have hard details on .gitignore on a per language or IDE level.
Github came out with a very useful, community collaborated list of .gitignore files for all sorts of projects and IDEs that is worth taking a look.
Here's a link to that git repo: https://github.com/github/gitignore
To answer the question, here are the related examples for:
C# -> see Visual Studio
Visual Studio
Java
Eclipse
Python
There are also OS-specific .gitignore files. Following:
Windows
OS X
Linux
So, assuming you're running Windows and using Eclipse, you can just concatenate Eclipse.gitignore and Windows.gitignore to a .gitignore file in the top level directory of your project. Very nifty stuff.
Don't forget to add the .gitignore to your repo and commit it!
Chances are, your IDE already handles this for you. Visual Studio does anyway.
And for the .gitignore files, If you see any files or patterns missing in a particular .gitignore, you can open a PR on that file with the proposed change. Take a look at the commit and pull request trackers for ideas.
I am always using www.gitignore.io to generate a proper one .ignore file.
Opinion: everything can be in source control, if you need to, unless it brings significant repository overhead such as frequently changing or large blobs.
3rd party binaries, hard-to-generate (in terms of time) generated files to speed up your deployment process, all are ok.
The main purpose of source control is to match one coherent system state to a revision number. If it would be possible, I'd freeze the entire universe with the code - build tools and the target operating system.
