Changing colour of beamer blocks

5 For "normal" blocks (`block`, `alertblock`, `exampleblock`) that's easy, one can set their dedicated beamer colours:

How to uncover minted code line by line in a beamer presentation? 2

5 You should have a look at the package `piton`. When you use the class Beamer, in an environment `{Piton}` of `piton`, you only have to use the usual syntax of Beamer (the commands `\uncover`, etc. or the environments `{uncoverenv}`, etc.) directly in the listing you want to format.

4 Both `\pause` and `\onslide<…>` seem to work, the latter needs minted's `beameroverlays` option set as `<` and `>` are treated differently otherwise.

2 One possible approach is to use the `tikzmark` library to cover up the future lines with a rectangle of the same colour as the background:

5 If you would like the line to be at the right edge of your frame, you could add them via the sidebar template:

Hiding label of a tikz node with beamer overlay 2

J...S J...S

4 You can give options to the node using the syntax `label=[<options>]<position>:<contents>`. Note that you need to put `{}` around the entire `label`-value in order to hide the `]` from the parser searching for the end of the optional argument of `\node`.

1 Quick hack: change the text opacity on the first overlay:

0 Another quick hack: use `alt=<2>{label=above:{Process}}` to only add the label to the second overlay and use an invisible rectangle to avoid jumping of the image.

3 Quick hack: you don't have to worry about your image jumping around if it has the same size on all overlays. To ensure this, draw an (invisible) rectangle which encompasses the whole image:

2 You could temporarily change the opacity of the `initial`:

Oh, look at this shiny new beamer toy! https://github.com/Qrrbrbirlbel/tikz-extensions/releases/tag/0.6.1

samcarter

Perfect -- thanks a lot for the advertisement!

Skillmon

@samcarter is this ok or something you want changed? https://github.com/Skillmon/ltx_xistercian/commit/ec817793ec4bf7fbb5ca04360c76a5bb00fcc143

oooohhhh

निरंजन replying to CarLaTeX

It's not my language, but a neighboring language and we share the script except some small differences. So we visually look similar. My language is Marathi which is there in the learnlatex ethos [from a long time](https://www.learnlatex.org/mr).

CarLaTeX

@निरंजन Is it your language?

निरंजन replying to J...S

Yupp, I don't think Ti*k*Z needs a separate command, or even if it does, it's just `\def\tikzlogo{Ti\textit{k}Z}`.

J...S replying to निरंजन

Thanks. hologo has macros for metapost and metafont.

J...S replying to samcarter

Lovely!

samcarter replying to J...S

If you ask a question I could show you some code (might take until tomorrow, travelling atm)

निरंजन replying to samcarter

Lovely! This probably should be a question and an answwer for reference.

samcarter replying to J...S

Tikzmarks, I've happened to have done that just yesterday https://raw.githubusercontent.com/samcarter/samcarter/main/ressouces/Dante2025_Cookies.pdf

निरंजन replying to J...S

[`hologo`](https://ctan.org/pkg/hologo), [`metalogox`](https://ctan.org/pkg/metalogox).

J...S replying to samcarter

Is there a way to uncover a code snippet line by line in beamer with minted?

J...S

There are built-in macros to render TeX (`\TeX`) and LaTeX (`\LaTeX`), right?  
Are there similar macros for other names?  
Like TIkZ and metafont?

samcarter replying to Skillmon

:D

Skillmon

Wait, who forgets arguments? The occasional element separator might be left out, but entire arguments?

samcarter replying to Skillmon

The arguments are at least consistent in minted  and not some highlighted and some forgotten :)

Skillmon replying to samcarter

:) I know. But arguments are also not highlighted in `minted` are they? I thought it only highlights the braces.

samcarter replying to Skillmon

macros are only the tip of the ice berg: environments, arguments ...

Skillmon replying to samcarter

For LaTeX-stuff you don't necessarily need to define any keywords in `listings` as well: `keywordsprefix = \\` (untested, but should do)

samcarter replying to Skillmon

... or use beamer with minted :P  
  
(for the moment, I'm quite happy with minted as I don't have to define any keywords etc.)

Skillmon replying to samcarter

forgot to tag this as a reply^^^

Skillmon

In that case use `listings` (provided it works with tagging, I have no idea)

samcarter replying to Skillmon

Joseph had an example which also reproduces the error with article + `\DocumentMetadata{testphase = latest}`

samcarter replying to Skillmon

Thanks for the offer! But if I understood Ulrike correctly, there is also a problem between minted and the tagging stuff.

Skillmon replying to samcarter

I'm confident we can make a q&d `fragile`-draft work. Do you want me to patch something together?

samcarter replying to Skillmon

and yes, I'll be talking about cookie cutters :P

samcarter replying to Skillmon

Yes, `Cookies.pdf` are all the beamer slides with minted, which I can't yet move to xbeamer.

Skillmon

Aside: Is this your upcoming DANTE talk?

Skillmon replying to samcarter

depends on the contents of `Cookies`. Is that the result of a `beamer` presentation? If so: No. Imho, including some pages of another document is fine, but except for the titlepage your entire contents are not done using `xbeamer`, I'd say this hardly qualifies. Sorry :)

Skillmon replying to निरंजन

it's not nearly done. We had some initial setup done roughly a year ago. Lately Joseph is tackling it more fully, so currently the project is quite active (and Joseph carries the vast majority of it). But on many things we're still in the design phase. So you're welcome to participate in discussion on that repository. The overall aim is to have a tagging-aware and compatible replacement of `beamer` that has sane and idiomatic LaTeX under the hood (don't understand me wrong, `beamer` is an amazing thing, but it consists of many incoherent, undocumented, and very non-standard parts of code).

samcarter replying to निरंजन

It isn't yet finished, but you can have a look at https://github.com/josephwright/xbeamer

निरंजन replying to samcarter

Where do we read about xbeamer? It doesn't seem to be a CTAN package.

samcarter replying to CarLaTeX

I like this approach!

CarLaTeX replying to samcarter

let's do not look at the details... :D

samcarter replying to CarLaTeX

It feels a bit like cheating if I only 5% of the document are created with xbeamer :)

CarLaTeX replying to samcarter

Why not?

samcarter

no

samcarter

yes

just love all these ducks and dogs and whatever...   
 having fun right now with a little package called "ducksay", really a nice one

AdelheidBausB

that makes me start the weekend with relief :-D ;-) otherwise a fence would have been recommended...

Skillmon replying to AdelheidBausB

Story time: My family once was on a vacation in France along with our family dog. Our landlord had ducks in a small pond on the property. One day my mother was sunbathing and reading in the garden when our dog brought her one of the ducks between here teeth. My mother was shocked and ordered the dog to let go of the duck. When she (the dog) opened her mouth the duck fell to the ground, unscathed only with a few tousled feathers and ran off. Morale of the story: No, they do play catch but don't harm them.

AdelheidBausB

... are dogs eating ducks? Just asking ;-)
