Can giter8 run CLI commands? - scala

As far as I can see giter8 can make a parameterized copy of a given template directory tree, but that would be only part of what many people do to prepare a new project. As an example a git repository could be initialized via the git CLI. More generally it would be useful to run arbitrary commands from a template or additionally to a template.
Can giter8 run arbitrary shell commands?
Is there a tool that can run arbitrary shell commands additionally to giter8 or as an alternative to it?

Some beginner questions about Centreon

I am new to Centreon and I have a few questions I need to figure out. I have these services:
I just want to know how can I have these services like this.
2nd question
on Github, I find that the plugin is end with .pm not .pl, which is I wonder why, and how to use the plugin on Github, because I already put it in on a folder on Centreon and restart it on the poller, but I do not see the plugin I downloaded.
3rd question
For interfaces:
--plugin=os::linux::snmp::plugin --mode=interfaces --add-status --add-traffic
For services (if it's windows):
--plugin=os::windows::snmp::plugin
Is this just command or I have to modify it on a plugin ?
You must have create a new host and link to this host an host template. This host template is linked to services and this why you have services created. Do not hesitate to check this documentation
To use our centreon plugin you have two different way to do:
Clone our GitHub repository Here, and manage your script file by file use the centreon_plugins.pl to call the .pm file through the --plugin option, through the following command line you can download the repo:
git clone https://github.com/centreon/centreon-plugins.git
Use the Centreon RPM packages, who they correspond to the GitHub script, but all build per kind of devices (one .pl script per devices). You can install them with the following command line:
yum install --nogpgcheck centreon-plugins\*
By default all nagios plugins are stored in "/usr/lib64/nagios/plugins/" and the centreon plugins are stored in "/usr/lib/centreon/plugins/"
'--plugin' option is related to a command and it just indicate the plugin that will be used, you don't need to modify any plugin just the command unless you want to change something inside the plugin.

Programming in Swift on Linux

I would like to prepare the environment for working with Swift on Ubuntu 16.04.
I installed Swift and Atom editor.
I installed the Script package, which allows me to run code from the Atom editor.
Generally it is nice when I compile and run one file (Ctrl+Shift+B shortcut).
The problem is when I would like to build a project composed of several files.
Classes defined in the other files (not the one I compile) are not visible (compilation error).
Is it possible to configure the editor to compile and run the entire project?
How to import external library, eg ObjectMapper ?
You can use the Atom package build. It allows you to create custom build commands and such by using common build providers. You can build with a Makefile or JSON or CSON or YAML or even Javascript. It provides enough flexibility that you can build just about anything. Just make your build file so that it points to all the files to build with the right compiler (probably swiftc in your case). With a Javascript build file, you can even specify a command to run before and after the build, say, to run your newly built program.
There's a great open source project I have been watching called Marathon. It's a package manager and they have been Working on a deployment on linux. I'm not sure how much success they have had, but you can follow along here and maybe help out.
https://github.com/JohnSundell/Marathon/issues/37
Edit: It looks like it does work on linux!
git clone https://github.com/JohnSundell/Marathon.git
$ cd Marathon
$ swift build -c release
$ cp -f .build/release/Marathon /usr/local/bin/marathon
For dependencies, you should use Swift Package Manager.
You can check how Vapor is built - it is prepared for build apps for Ubuntu too.
Also, Vapor toolbox would help you with other projects
https://docs.vapor.codes/2.0/getting-started/install-on-ubuntu/
You can build a Swift project using VS Code + Swift Development Environment extension

Component-preload.js generation

We are about to close a SAPUI5 application, one of the last steps is to make a Component-Preload.js file to improve performance. I read different guides around the web, all of them need Node.js that I have installed. I'm not expert about that package and I can't figure how to make one of that guides work. I'm developing with NetBeans. As far as I see there is not an official tool (am I right?) to generate that file. Can someone with more experience than me suggest a working, well-explained guide to perform that task?
I don't know if this could help, that's my working tree:
There are several main ways of doing it.
You can use SAP Web IDE to generate it. This assumes that you are using WebIDE to develop your application (which is not true based on your question). The regular version of WebIDE generates this file during the "client build" just before application deployment.
The "multi cloud" version of WebIDE can use a grunt build to do it. You can find more info here if you are interested: https://www.sap.com/developer/tutorials/webide-grunt-basic.html.
Use the new UI5 command line tools (https://npmjs.com/package/#ui5/cli):
Run npm i -g #ui5/cli to install the tools globally.
Open the root of your project with your terminal.
Run ui5 build preload to build the preload.
Use the #sap/grunt-sapui5-bestpractice-build pre-configured grunt tasks. The downside is that they are more-or-less black boxes which do not allow that much customisation. You can find an example setup on SAP's GitHub repository jenkins-pipelines. In a nutshell:
You need to define an .npmrc file which adds the #sap npm registry: #sap:registry=https://npm.sap.com.
Run a npm init command such that you generate a package.json file. This file describes your application and your dependencies (runtime dependencies and dev dependencies; you will only have dev dependencies for now, as you just want to build your app). Make sure to mark the package as private. See the npm docu (at the end of the license chapter).
Then you can install grunt and the build configuration: npm i grunt -D and npm i #sap/grunt-sapui5-bestpractice-build -D.
Lastly you need to define a simple Gruntfile (you can then run the build by just running grunt):
module.exports = function (grunt) {
'use strict';
grunt.loadNpmTasks('#sap/grunt-sapui5-bestpractice-build');
grunt.registerTask('default', [
'lint',
'clean',
'build'
]);
};
You can use the official grunt_openui5 plugin to generate the preload file(s). In order to be able to do this, you need to have node installed:
Create a package.json (e.g. through npm init).
Install grunt by writting in the console: npm install grunt-cli --save-dev.
Install the official openui5 grunt plugin: npm install grunt-openui5 --save-dev.
Now you have all the tools necessary, you just need to tell grunt what it has to do. You should create a Gruntfile.js in the root of your project. In this file you should configure the grunt openui5 task as described in the official github page (I linked it above). You can find a similar file here (it has more build steps like minification and copying the result files in a separate directory).
You can then run the grunt build by simply running grunt <task_name> in the console. If you registered your build task as the grunt default task (like in the sample file: grunt.registerTask('default', [...]);) then you just have to write grunt.
I think you should be able to integrate such a command line script (i.e. to run grunt) inside your IDE as an external tool.
You can use the unofficial gulp-openui5 tool to generate it. I would not recommend this if you are not already using gulp for your builds (as it is not a tool built by SAP). The procedure is the same, but using gulp for building the app instead of grunt (so you need to install node, npm init, install gulp, create the Gulpfile, etc).
Note that for most of the above methods, you need nodejs, which you can download and install from here: https://nodejs.org/en/download/.

How do I get the commands executed by Bazel

I was wondering if there is a way to get Bazel to list, output, display, etc., all of the commands that can be executed from a command line that are run during a build after a clean. I do not care if the output is to the screen, in a file, etc. I will massage it into a usable form if necessary.
I have captured the screen output during a run of Bazel which gives me an idea of what is being done, however it does not give me a command I can execute on the command line. The command would have to include all of the command options and not display variables.
If this is not possible, since Bazel is open source, where in the code is/are the lines that represent the commands to be run so that I can modify Bazel to output the executable commands.
I am aware of the query command within Bazel, and used it generate the dependency diagram. If this could be done as a query command it would be even better.
TLDR;
My goal is to build TensorFlow using Bazel on Windows. Yes I know of all of the problems and reasons NOT to do it and have successfully installed TensorFlow on Windows via a Virtual Machine or Docker. I did take a shot at building Bazel on Windows starting with Cygwin, but that started to get out of hand as I am use to installing with packages and Cygwin doesn't play nice with packages, so then I started trying to build Bazel by hand and that was turning into a quagmire. So I am now trying to just build TensorFlow by hand on Windows by duplicating what Bazel would do to build TensorFlow on Linux.
You are correct, you can use the -s (--subcommands) option:
bazel build -s //foo
See https://docs.bazel.build/versions/master/user-manual.html#flag--subcommands.
For your use case, you'd probably want to redirect the output to a file and then global replace any library/binary paths to the Windows equivalents.
You might want to track https://github.com/bazelbuild/bazel/issues/276 (Windows support), although it'll probably be a while.
(Disclaimer: This solution does not print the commands that currently get executed but the commands that would get or got executed.)
I'd use aquery (action graph query) (forget about "graph"):
bazel aquery //foo
Advantages:
It's very fast, because it prints the actions without executing the build.
It's a query. It does not have side effects.
You don't have to do a bazel clean before in order to find out the build steps for a library that has already been built.
It prints information about the specific build step that you request. It does not print all the build commands required for the dependencies.

How to check for running process or service in gradle

I have a gradle build, which runs a few tests on our application. Currently the tests that store assets in mongoDB fail if the developer forgets to run mongod first. So I want any build that uses mongoDB to fail with a message the user that clearly tells him to start mongoDB. Ideally, later we would start mongoDB from gradle.
I already found this nice article about how to see if mongoDB is running under Linux, which is quite simple. I am sure something similar can be done under Windows using tasklist /FI "IMAGENAME eq mongod", etc. But I need to know how to use this correctly in gradle.
Is there a cross platform way to check if a service or normal process is running in gradle?
The suggestion provided by Orid to use the Gradle Mongo Plugin should work if you set the necessary Gradle tasks to be dependent on a startManagedMongoDb task.
While that may seem to be the easiest way, it may be breaking with how MongoDb will be used in non-development environments or on a continuous integration build-server, where the MongoDb service will already be running.
A very simple solution would be to add the MongoDb checking functionality to the top of a customized gradlew.bat (and the gradlew bash script if it will be run on a *nix operating system).
Another simple solution that wouldn’t require changing the gradlew.bat script would be to create your own MongoDb checking script that then called gradlew.bat, passing on command line arguments. I’m not sure if there is an equivalent to the bash $# for all positional arguments in windows, but looping through the arguments with SHIFT %1 can be used to generate the gradlew.bat command line.
