    Perfect! So glad this exists!

    Thanks for the feedback! Just to re-state my case in clearer terms: For my personal workflow (others may differ), compiling to html is only done once at the end of a session, and t…

    I wish there was a better way to run quarto as a script, as in, as fast as `source` in R and `include` in Julia. Current behavior 1. Has scoping rules that make it difficult to deb…

    Have you tried DataFramesMeta.jl? It has a tutorial for people familiar with tidyverse. See [here]( https://juliadata.org/DataFramesMeta.jl/stable/dplyr/ ).

    Maybe [this]( https://m3g.github.io/JuliaNotes.jl/stable/workflow/ )? The key is to work with modules, use Revise.jl, and Infiltrator.jl.

    Jupyterlab is just an IDE. You can open up terminals, consoles (which are like notebooks, but are a console), and notebooks, on top of a text editor. It's actually really nice. Wor…

    I think small businesses owners often treat their workers badly and are overall a reactionary force in American politics. But sympathy makes a bit of sense when you think about it …

    Thanks for the detailed response. Yeah allocation seems like the biggest hangup here. I would rather have a function stick to a "no allocating" contract and allow for some undefine…

    What semantics are expected in other languages? This seems solidly in the realm of undefined behavior as far as I can tell.

    I don't get these complaints about `sum!(a, a)`. Sure it's a bit of a footgun that you can overwrite the array you are working with. This doesn't rise to a "major problem" of compo…

    In Julia you could have an `AbstractVector` type also be callable, or more likely a vector of callable objects (and the operation is performed row-wise). I agree it's unlikely that…

    It would be interesting to profile the 2nd version though. Assuming the non-standard evaluation has performance benefits (which they do in DataFramesMeta.jl), are you eliminating t…

    Comment #30086138

    Let's say you have a data frame df = tibble(a = c(1, 2)) and you want to use a dplyr verb to modify it mutate(df, b = a + 1) the `a` in the above expression refers to the column in…

    Yes it absolutely needs a new name!

    DataFramesMeta.jl might be exactly what you are looking for then! The syntax is very close to dplyr, but has performance benefits thanks to Julia. Here is a tutorial for those fami…

    Hello everyone. Hackernews has been discussing excel a lot the past few days. Fortunately, this conversation coincided with a release of a Julia package I've been working on, ClipD…

    Just that there seems to be an expectation of using Rstudio when using things in R that seem generic. One pain point is that Rmarkdown uses a different pandoc installation when exe…

    Yeah people in python are used to doing `python script.py` all the time, and that's not very convenient in julia. sysimages are great, as is daemonmode. But really just do Revise a…

    QtConsole is actively maintained. I don't use it but I do like it a lot.

    Plenty of people use the REPL in terminal and sublime text or vim or whatever. I also dislike browser-based tooling and think Julia has done a good job avoiding Rstudio-style depen…
