feat(18): not really working docker images

wrapping + into span inline, to make it behave like part of
surrounding text in a div, somewhat ok

+*** What I learned
+:PROPERTIES:
+:CUSTOM_ID: what-i-learned
+:END:
+**** polling download for 'infinite scroll'
+https://htmx.org/examples/infinite-scroll/
+
+I've done almost same thing as example,
+but i'm appending additional empty div, that inserts responses instead of itself
+
+this way i have one template fragment with repeater,
+and don't have to add hx attributes to the last one,
+
+i just have separate fragment that i append to response which will trigger new
+load on enter view.
+**** having html 5 native autocomplete with <datalist> tag
+just server side rendering it with all country names is yay
+**** inserting thymeleaf templates by css selector
+https://www.thymeleaf.org/doc/tutorials/3.1/usingthymeleaf.html#appendix-c-markup-selector-syntax
+
+this way i can insert <script> tag from index page, without declaring it as a fragment,
+because i'll want is static anyway.
+
+and can share 'dark mode' js code between pages
+**** building docker image
+First off: using nix docker tools, and sbt assembly to create 'uber jar'
+now 'nix build .#countries-page-image' builds an image and symlinks it to ./result
+
+$ docker load < result
+loads the image
+
+and it can be started
+$ docker image list
+$ docker run -d -p 9090:8080 <image-id>
+**** deploying to render.com
+need to auth the docker cli, then tag an image with my repository name
+$ docker login
+$ docker tag 141 efim1234/rock-paper-scissors:latest
+$ podman push localhost/efim1234/countries-page:latest     docker.io/efim1234/countries-page:latest
+
+and now render.com, when creating "new service"
+can find "efim1234/countries-page:latest" as public image and use it
+**** using browser history
+with either server side
+HX-Push -> "some-url"
+or
+hx-push-url="true" in the html side
+
+so that url is put into address bar,
+and browser save the body into history
+
+and now my website has forward and backward navigation
+
+only bug - the 'filter by region' for some reason doesn't maintain the selected value
+
+*** Continued development
+:PROPERTIES:
+:CUSTOM_ID: continued-development
+:END:
+In future project i'll probably want to lean and use go.
+For smaller binaries of the server, using PocketBase as embedded backend functions,
+and maybe having a better chances of just doing some real world small projects.

+Hanken Grotesk Variable Font
+============================
+
+This download contains Hanken Grotesk as both variable fonts and static fonts.
+
+Hanken Grotesk is a variable font with this axis:
+  wght
+
+This means all the styles are contained in these files:
+  HankenGrotesk-VariableFont_wght.ttf
+
+If your app fully supports variable fonts, you can now pick intermediate styles
+that aren’t available as static fonts. Not all apps support variable fonts, and
+in those cases you can use the static font files for Hanken Grotesk:
+  static/HankenGrotesk-Medium.ttf
+  static/HankenGrotesk-Bold.ttf
+  static/HankenGrotesk-ExtraBold.ttf
+
+Get started
+-----------
+
+1. Install the font files you want to use
+
+2. Use your app's font picker to view the font family and all the
+available styles

+**To do this challenge, you need a decent understanding of HTML, CSS and JavaScript.**
 
 ## The challenge
 
-Your challenge is to integrate with the [REST Countries API](https://restcountries.com) to pull country data and display it like in the designs.
+Your challenge is to build out this bar chart component and get it looking as close to the design as possible.
 
-You can use any JavaScript framework/library on the front-end such as [React](https://reactjs.org) or [Vue](https://vuejs.org). You also have complete control over which packages you use to do things like make HTTP requests or style your project.
+You can use any tools you like to help you complete the challenge. So if you've got something you'd like to practice, feel free to give it a go.
+
+We provide the data for the chart in a local `data.json` file. So you can use that to dynamically add the bars if you choose.

+Your task is to build out the project to the designs inside the `/design` folder. You will find both a mobile and a desktop version of the design. 
-
-In this challenge, you will find mobile and desktop designs in light and dark mode color schemes for both pages.
 
 The designs are in JPG static format. Using JPGs will mean that you'll need to use your best judgment for styles such as `font-size`, `padding` and `margin`. 
 
 If you would like the design files (we provide Sketch & Figma versions) to inspect the design in more detail, you can [subscribe as a PRO member](https://www.frontendmentor.io/pro).
 
-There are no assets for this challenge, as the country flags will be pulled from the [REST Countries API](https://restcountries.com) and you can use an icon font library for the icons.
+You will find all the required assets in the `/images` folder. The assets are already optimized.
 
 There is also a `style-guide.md` file containing the information you'll need, such as color palette and fonts.

+* new exersice after long time
+now will be learning https://github.com/a-h/templ
+it's a templating solution for go, more similar to jsx
+but it also needs a pre-processing step, so i'm adding it like tailwind
+
+with Makefile for make run/live
+and will need to add as a step in project build
+
+* setting up 
+https://git.sunshine.industries/efim/golang-templ-and-tailwind
+have separate repo, but i guess i'll remove .git from this dir,
+to have single commits across Learning HTMX?
+
+or maybe magit will just allow for simple integration?
+just not pushing into origin, committing, and then committing from overall repository?
+
+** not so simple, but still quite OK!
+
+there's now 'subtree' which is separate concept from submodule,
+and it is maybe simpler:
+
+https://magit.vc/manual/magit/Subtree.html
+
+i'm using the repo url
+ssh://gitea@git.sunshine.industries:65433/efim/golang-templ-and-tailwind.git
+
+and the command magit subtree add,
+specify the directory, and it gets embedded it seems.
+i have one level magit dispatch and my notes would be committed to the main repo,
+i would potentially be able to pull in commits from the parent?
+
+and maybe somehow contribute, but yeah, this is still confusing 🙂
+how would i commit to subtree upstream if there are conflicting changes?
+maybe i'll just get denied, as simple as that.
+
+allright! let's add exercise specific data (again)
+
+* so, starting dev
+
+old process:
+1. open second browser and open png with style
+   first mobile
+2. enable view C-S-m in firefox
+   the responsive mode
+
+i suppose next is adding colors to tailwind configuration?
+from the styleguide file
+
+also
+3. check desktop style, whether any big rearrangements are required
+   so that i'd start mobile with way to rearrange things
+
+do i have a separate note with all of these things?
+i've also used some commands to vertically center my stuff
+
+** DONE allright, tailwind config go
+font, size, colors
+
+** well, i don't really want to go on.
+but yeah, i'll need hierarchy of the elements.
+
+** ok. thoughs:
+the componets would be
+- my balance bubble
+  because it is spacially separate
+- spending summary
+- graph inside spending summary
+  or maybe don't even need that
+
+the component should take up all space provided to it.
+if parent would want to add space around - that's easy to do,
+but if component insists on adding space around itself - harder to reuse?
+because then if parent would want to have child take up all space - negative padding?
+
+*** allright, @ to include sub templates
+
+** well, last part? preparing the docker container for deployment on Render.com?
+
+which port should be used?
+also, this would be first time i'll add templ as a build step
+
+** for some reason image doesn't work well
+
+podman run -d -p 9090:8080 localhost/expenses-chart:latest  /nix/store/l4r6glmzbvkhg97lp4dn7nm76w6hz41g-expenses-chart-0.0.1/bin/temp-exercise

+
+oh, well
+
+** you know what - i give up
+
+for some reason when i open url to app running in container,
+and it's on the 8080 port of the host machine - the static files are served
+
+if i use any other port of local machine, to forward into container,
+the static files are not served
+
+maybe this is bug in go? i don't know
+StripPrefix doesn't seem to do anything
+
+and for some reason in this specific exercise CMD doesn't work in the container
+so let's just give up!
+
+i could try to write a docker file and check with that, but yeah
