Are setenv hudson plugin variables accessible in status email? - hudson

I installed the SetEnv plugin and it works fine for getting the variables during a task.
unfortunately when i try to use the env variable in the resulting status email I have no luck at all. Is this supposed to work?
I've tried both $VARNAME and ${VARNAME} - neither of which get replaced correctly in the email.

The simplest way to use environment variables (or any variables) in your email notifications is by using the Email-ext plugin.
Check their "Content token reference" for specifics but in short you get much more sophisticated substitution. Heres a few I use regularly:
${ENV, var} - Displays an environment
variable.
${BUILD_LOG_REGEX, regex, linesBefore, linesAfter, maxMatches, showTruncatedLines} - Displays lines from the build log that match the regular expression.
${CHANGES_SINCE_LAST_SUCCESS, reverse, format, showPaths, changesFormat, pathFormat} - Displays the changes since the last successful build.
${FAILED_TESTS} - Displays failing unit test information, if any tests have failed.
The plugin makes it easy to define a base "global" template in the Hudson configuration then sort of "extend" that template in your job configuration- adding additional detail. It also allows you to route notifications more granularly based on the build status/outcome.

This is possible already. It looks like you're using the wrong syntax. As mentioned previously, the email-ext plugin has a specific method for accessing environment variables. Try putting this in the email body instead:
${ENV, var=VARNAME}
An alternative method would be to use Hudson's execute shell feature to echo the environment variable during the build and parsing for it using BUILD_LOG_REGEX.
For example, you could have this in the Execute Shell part:
echo "Output: ${VARNAME}"
and parse it in the email using
${BUILD_LOG_REGEX, regex="^Output:", showTruncatedLines=false, substText=""}

It looks like I will have to wait for this:

Discord.py assistance - How does the library forcibly call an asynchronous command function?

I have used many discord API wrappers, but as an experienced python developer, unfortunately I somehow still do not understand how a command gets called!
#client.command()
async demo(ctx):
channel = ctx.channel
await channel.send(f'Demonstration')
Above a command has been created (function) and it is placed after its decorator #client.command()
To my understanding, the decorator is in a way, a "check" performed before running the function (demo) but I do not understand how the discord.py library seemingly "calls" the demo function.....?? Is there some form of short/long polling system in the local imported discord.py library which polls the discord API and receives a list of jobs/messages and checks these against the functions the user has created?
I would love to know how this works as I dont understand what "calls" the functions that the user makes, and this would allow me to make my own wrapper for another similar social media platform! Many thanks in advance.
I am trying to work out how functions created by the user are seemingly "called" by the discord.py library. I have worked with the discord.py wrapper and other API wrappers before.
(See source code attached at the bottom of the answer)
The #bot.command() decorator adds a command to the internal lists/mappings of commands stored in the Bot instance.
Whenever a message is received, this runs through Bot.process_commands. It can then look through every command stored to check if the message starts with one of them (prefix is checked beforehand). If it finds a match, then it can invoke it (the underlying callback is stored in the Command instance).
If you've ever overridden an on_message event and your commands stopped working, then this is why: that method is no longer being called, so it no longer tries to look through your commands to find a match.
This uses a dictionary to make it far more efficient - instead of having to iterate over every single command & alias available, it only has to check if the first letters of the message match anything at all.
The commands.Command() decorator used in Cogs works slightly different. This turns your function into a Command instance, and when adding a cog (using Bot.add_cog()) the library checks every attribute to see if any of them are Command instances.

As you can see, it calls add_command() internally to add it to the list of commands.

You'll have to follow the chain - most of the processing actually happens in get_context which tries to create a Context instance out of the message: https://github.com/Rapptz/discord.py/blob/24bdb44d54686448a336ea6d72b1bf8600ef7220/discord/ext/commands/bot.py#L1231

Parsing terraform plan output to check for module vs resource block usage

I wanted to add a check to an existing terraform build and deployment pipeline to check that the configuration being written by devs is properly formatted and in line with company syntax
Specifically I want to check to make sure they are not using plain resource blocks in thier config as opposed to module blocks
For example I want to I want to make sure they are using
Module “eks_dev_wus2_app_cluster”
And not
Resource “aws_kubernetes_cluster” “eks_dev_wus2_App_cluster”
Current approach
As I understand it I would need to first convert to json to parse through it
terraform show -no-color -json output.tfplan > output.json
Then I should use the jq tool to parse through the output per this article
https://linuxconfig.org/how-to-parse-a-json-file-from-linux-command-line-using-jq
A little fuzzy on how I would go about specifically checking the blocks in the terraform config to confirm whether or not they are resource or module.
Can anyone point me in the right direction?
Is there a better way to get output values? Don’t need an entire solution, just looking to clarify some of the fogginess of approaching this problem
Under the output format, there is a list called resource_changes. Each change has an address field. To meet your requirement, each address should start with module. This makes the developer responsible only for the modules that they are changing with this terraform plan.
Assuming you already have output.json in place, you could do it like this:
LIST=$(cat output.json| jq -r ".resource_changes[].address")
for ADDRESS in $LIST
do
if [[ $ADDRESS != "module."* ]]; then
echo "$ADDRESS is outside of a module"
exit 1
fi
done

Remove debugger keyword during compilation in google closure

UPDATE:
The JS version of closure-compiler is no longer supported or maintained.
https://github.com/google/closure-compiler-npm/blob/master/packages/google-closure-compiler-js/readme.md
Im trying to find if there is a way to remove the "debugger" keyword during compilation process, im using the javascript version google-closure-compiler with gulp.
Looking through the documentation it is clear we can set the flag to stop/show error messages during compilation by doing the following.
https://github.com/google/closure-compiler/wiki/Flags-and-Options
--jscomp_off
translating this to gulp, it is:
const googleClosureOptions = {
...
jscomp_error:"checkDebuggerStatement"
}
however this works on stopping the compilation by throwing error or to show a warning.
zyxcdafg.js:1444: ERROR - [JSC_DEBUGGER_STATEMENT_PRESENT] Using the debugger statement can halt your application if the user has a JavaScript debugger running.
debugger;
^^^^^^^^^
but what I am trying to achieve is to remove the debugger keyword. Is this possible to achieve using googleclosure. I can not find any flags or options relating to this.
UPDATE:
The JS version of closure-compiler is no longer supported or maintained.
https://github.com/google/closure-compiler-npm/blob/master/packages/google-closure-compiler-js/readme.md
No I don't think so. I'd suggest you use something else to do it. Like sed:
find dist -name "*.js" -exec sed -i 's/\sdebugger;//' {} +
Something like that will find files in your dist folder that end with .js and then exec-ute sed to replace all instances of debugger; with nothing.
You could add that to a script that calls your Closure Compiler build.
The compiler doesn't have a command-line api for defining custom code removal passes, but the compiler's architecture does allow for registering custom passes and a pass to remove a debugger statement should be trivial:
if (n.isDebugger()) {
compiler.reportChangeToEnclosingScope(n);
n.detach();
}
The general structure would follow:

How do I make an Storyblok-API call with multiple parameters incl. "filter_by"?

So far I have seen, the API allows me to add certain parameters to my calls such as filter_by and sort_by.
This works well for me, but I would like to know how do I use multiple parameters at the same time and using the filter_by parameter.
Currently, I am working with the Silex-Boilerplate, which offers me this function:
options('{"sort_by":"name:asc","is_startpage":false}')
I have tried to pass this JSON as options-parameter:
'{"filter_by":"{"component":"reference"}", "sort_by":"name:asc"}'
But it doesn't seem to work. Are there any suggestions about how the JSON could look like?
Thanks in advance!
As I can see you're already using the options Twig helper which is the right way to go.
options('{"sort_by":"name:asc","is_startpage":false}')
you can use the filter_by parameter directly using this syntax:
options('{"sort_by":"name:asc","filter_by[component]":"reference"}')
Also this syntax would be possible:
getStories('starts_with', 1, 10, 'name:ASC', options('{"filter_by":{"component":"reference"}}'))
this will be mapped directly for the API call by our PHP Client Library. Those requests are also cached in your Silex Boilerplate without any extra effort.

Jenkins/Hudson job parameters at runtime?

PROBLEM
Let's say I have a jenkins/hudson job (for example free-style) that takes two parameters PARAM_ONE and PARAM_TWO. Now, I do not know the values of those parameters, but I can run some script (perl/shell) to find values of those parameters and then I want the user to select from a dropdown list after which I can start the build.
Is there any way of doing that?
Sounds like you've found a plug-in that does what you need, that is pretty similar to the built-in Parameterized Builds functionality.
To answer your second question: when you define parameterized builds, the parameters are typically passed to your job as environment variables. So you'd access them however you access environment variables in your language, for instance, if you defined a parameter PARAM_ONE, you'd access it as:
In bash:
$PARAM_ONE
In Windows batch:
%PARAM_ONE%
In Python:
import os
os.getenv('PARAM_ONE')
etc.
I imagine this would be the same for the Extended Choice Parameter plugin you are using.
Just install this, and give the parameter in the build script like:
Windows
"your build script" %PARAMONE% %PARAMTWO%
In Java, you can access these parameters off the run object
EnvVars envVars = new EnvVars();
envVars = run.getEnvironment(listener);
for (String envName2 : envVars.keySet()) {
listener.getLogger().println(envName2 + " = " + envVars.get(envName2));
}
