Display an older version of a CQ page - aem

For audit purposes I got the requirment to create a tool where the authors can look at older versions of a CQ page. I managed to get the available versions with the JCR VersionManager using the following code (used in a SlingServlet with cq:Page as the resourceType):
Session session = request.getResourceResolver().adaptTo(Session.class);
VersionManager vm = session.getWorkspace().getVersionManager();
VersionHistory versionHistory = vm.getVersionHistory(request.getResource().getPath());
VersionIterator vIt = versionHistory.getAllVersions();
while (vIt.hasNext()) {
Version version = vIt.nextVersion();
String no = version.getName();
Calendar createdDate = version.getCreated();
// do something with it
}
The path of the version points to e.g. /jcr:system/jcr:versionStorage/d6/23/4f/d6234f36-3360-4024-bee2-411020ac63ae/1.0 where I can see a child node called jcr:frozenNode which seems to represent the jcr:content node of this specific version.
How can I tell CQ to render the page in this version? I would expect an url with some parameter or selector, but I didn't find any documentation. I tried to reverse engineer it with the Timewarp, but there the URL seems to be still the original and the magic is hidden somewhere.

I was also in contact with adobe support regarding this, and beside the timewarp there seems to be no built in feature to achieve this. Nevertheless I did some experimenting and found a feasible workaround. Though it might not be easy for a complex layout with many fixed components in the template, luckily on our case we mainly have a parsys.
So my solution is the following: I load the older version through two selectors in the url:
I called it "versionhistory" which is used to take another rendering script called versionhistory.jsp on the page component.
contains the actual version/node name (replacing "." with "_" to not add more selectors
In my versionhistory.jsp I just add the correct path for the parsys component (taking the example path from the question), and include the same layout elements as in the default script e.g. page.jsp:
<cq:include path="/jcr:system/jcr:versionStorage/d6/23/4f/d6234f36-3360-4024-bee2-411020ac63ae/1.0/jcr:frozenNode/par" resourceType="foundation/components/parsys" />

How can I find and edit/delete links from a Word document before JS requirement set 1.4?

I'm developing a MS Word Add-In using the JS API. Currently, I need to find and edit or delete specific links inside the entire document. I know that this works using context.document.body.fields and then item.result.delete() and item.result.insertText('new text', 'Replace'). But context.document.body.fields is only available in the latest versions of Word (technically since requirement set 1.4).
I just want to know, are there alternative ways to do this in older Word versions before rs 1.4? And if so, what are those?
I think you can use document.body.search() method to find the hyperlink and this method will return a Range object, you can futher call something like InsertText() to replace it or call range.hyperlink = "" to remove the hyperlink.

Can you get access to a pages front matter (or other data) in a eleventy (11ty) plugin

I'm creating (would like to create) an eleventy (11ty) plugin that can automatically generate Open Graph images based on a pages data. So in the template:
---
generate_og_image: true
image_text: "text which will be baked into the image"
og_image_filename: some_file_name.jpg
---
#some markdown
...
I can process each file in my .eleventy.js file via plugin using:
module.exports = function (eleventyConfig) {
eleventyConfig.addLinter("og-image-generator", function(content, inputPath, outputPath) {
title = HOW_TO_ACCESS_TEMPLATE_FRONT_MATTER
createImage(title)
});
}
But only have access to the content, inputPath and outputPath of the template.
How can I access the front matter data associated with the Template? Or is there a better way to go about this?
Answering my own question. As #moritzlost mentioned it is not possible directly. I found this workaround.
eleventyComputed allows you to dynamically assign values to keys. It also allows you to call a custom shortcode.
You can pass whatever properties you like from the template into the shortcode. In this case ogImageName the image name, ogImageTemplate a template or background image and text which is the text to be written on that background.
You can even pass in other keys from your front matter and process them as you go.
---
layout: _main.njk
title: "Some title here"
eleventyComputed:
ogImageName: "{% ogCreateImage { ogImageName: title | slug, ogImageTemplate: 'page-blank.png', text: title } %}"
---
Then in .eleventy.js or a plugin:
eleventyConfig.addShortcode("ogCreateImage", function(props) {
const imageName = props.ogImageName
const imageTemplate = props.ogImageTemplate
const imageText = props.text
console.log('-----------------ogCreateImage-----------------');
console.log(`filename: ${imageName}`);
console.log(`using template: ${imageTemplate}`);
console.log(`with the text : ${imageText}`);
// call the image creation code — return filename with extension
const imageNameWithExtension = createOGImage(imageName, imageTemplate, imageText)
return imageNameWithExtension
});
Returning the final filename which you can use in your template.
I've also come across this problem. I don't think what you're trying to do is possible at the moment. There are not many ways for a plugin to hook into the build step directly:
Transforms
Linters
Events
I think events would be the best solution. However, events also don't receive enough information to process a template in a structured way. I've opened an issue regarding this on Github. For your use-case, you'd need to get structured page data in this hook as well. Or eleventy would need to provide a build hook for each page. I suggest opening a new feature-request issue or adding a comment with your use-case to my issue above so those hooks can be implemented.
Other solutions
Another solution that requires a bit more setup for the users of your plugin would be to add your functionality as a filter instead of an automatic script that's applied to every template. This means that the users of your plugin would need to add their own template which passes the relevant data to your filter. Of course this also gives more fine-control to the user, which may be beneficial.
I use a similar approach for my site processwire.dev:
A special template loops over all posts and generates an HTML file which is used as a template for the generated preview images. This template is processed by eleventy. (source)
After the build step: I start a local server in the directory with the generated HTML files, open them using puppeteer and programmatically take a screenshot which is saved alongside the HTML templates. The HTML templates are then deleted.
This is integrated into the build step with a custom script that is executed after the eleventy build.
I've published the script used to take screenshots with Puppeteer as an NPM package (generate-preview-images), though it's very much still in alpha. But you can check the source code on Github to see how it works, maybe it helps with your plugin.

Make tile-ID request URL work with mapbox-style "satellite-streets" using folium

I use Python for plotting geospatial data on maps.
For certain map-styles, such as ["basic", "streets", "outdoors", "light", "dark", "satellite", "satellite-streets"], I need a mapbox-access token and for some geospatial plotting packages like folium I even need to create my own link for retrieving the map-tiles.
So far, it worked great with the style "satellite":
mapbox_style = "satellite"
mapbox_access_token = "....blabla"
request_link = f"https://api.mapbox.com/v4/mapbox.{mapbox_style}/{{z}}/{{x}}/{{y}}#2x.jpg90?access_token={mapbox_access_token}"
However, when choosing "satellite-streets" as mapbox-tile-ID, the output doesn't show a background map anymore. It fails with inserting "satellite-streets", "satellitestreets" and "satellite_streets" into the aforementioned link-string.
Why is that and how can I come to know what's the correct tile-ID-name for "satellite-streets"?
I found an answer when reaching out to the customer support.
Apparently, one has to access the static APIs which have specific names listed on their website:
"In general, the styles that you mentioned including
"satellite_streets" that you are referencing are our classic styles
that are going to be deprecated starting June 1st. I would recommend
using our modern static API the equivalent modern styles. This
will allow you to see the most updated street data as well.
Like the example request below:
https://api.mapbox.com/styles/v1/mapbox/satellite-streets-v11/tiles/1/1/0?access_token={your_token}
Here is more info on the deprecation of the classic styles and
the migration guide for them."
My personal adaptation after having tried everything out myself, is:
Via combining the above-mentioned with the details on how to construct a Mapbox-request link on this documention from mapbox' website,
I finally managed to make it work.
An example request looks like so (in python using f-strings):
mapbox_tile_URL = f"https://api.mapbox.com/styles/v1/mapbox/{tileset_ID_str}/tiles/{tilesize_pixels}/{{z}}/{{x}}/{{y}}#2x?access_token={mapbox_access_token}"
The tileset_ID_str could be e.g. "satellite-streets-v11" which can be seen at the following link containing valid static maps.

Typo3 Indexed Search Local_Lang path

i am wondering what TS code is needed to set path to my own indexed search local_lang.
I changed what i needed in pi1/local_lang but i would like to set it to my own so i can have the edited (Croatian in this case) for future projects.
Something like:
plugin.tx_indexedsearch.templateFile = fileadmin/search_temp.html
but for Local_lang of it?
with this lines you can overwrite individual translations:
plugin.tx_myPlugin_pi1._LOCAL_LANG.de.key = value;
plugin.tx_myPlugin_pi1._LOCAL_LANG.en.key = value;
I think that not all extensions supports a complete own localLang file, but not 100% sure.
You could add your translation to the official Translation Server . So your translation will be available trough the Translation Modul in TYPO3 Backend.
The croation translation for indexed_search is managed there: http://translation.typo3.org/hr/TYPO3.TYPO3.core.indexed_search/
There is a single-sign-on with typo3.org implemented. So you need an account on typo3.org first.

Remove custom code workflow programmatically

For a variety of reasons too convoluted to explain here, I find myself in a position where I need to be able to remove custom code workflows, while leaving the solution there.
I essentially have the same code as the plugin registration tool
Namely
service.Delete("plugintype", new Guid(info));
where info is the workflow id [running on a foreach loop but that's beside the point]
However, while the tool removes the workflows without any issues, my code complains about dependencies.
EM:
Additional information: The PluginType(a0b2dcf7-cf2a-111e-7da9-003021880a42) component cannot be deleted because it is referenced by 1 other components. For a list of referenced components, use the RetrieveDependenciesForDeleteRequest.
which I duly did
RetrieveDependenciesForDeleteRequest req = new RetrieveDependenciesForDeleteRequest();
req.ComponentType = 90; //plugintype
req.ObjectId = new Guid(info);
RetrieveDependenciesForDeleteResponse resp = (RetrieveDependenciesForDeleteResponse)OrgService.Execute(req);
This retrieves an optionvalueset, but there is little I can do with it as I cannot remove it from the solution as the solution is managed.
The only difference I can see is the way the OrganizationServiceProxy gets instantiated. The plugin registration tool includes a way to refresh the securitytoken, but as far as I can tell it's not doing much (I've stepped through the code, but it's possible I missed something)
Are you sure that it is an OptionSetValue that is the dependency? It's much easier to use GUI to determine what the dependencies are. Fire up your solution in CRM 2011, click 'plug-in assemblies', select the relevant assembly then go through each custom workflow/plugin item and click 'Show Dependences'.
In my case I had another workflow (created within CRM) that was referencing a custom workflow preventing removal of the assembly.
You won't be able to remove components from a Managed solution... Are you the author of the solution originally?
As an aside, does your workflow fire on change of the OptionSet that is showing as a dependency?
