Re: [BUG] Contents of the *Warnings* buffer, which has begun popping up at random intervals

[George Mauer]

Not at my computer now, but that looks like a warning I've been getting
pretty constantly for a few weeks and have an investigated. I assumed it
was coming from org-ai as I just recently added to that to my workflow and
use it a lot, but maybe not

Re: A dream?

[George Mauer]

Emacs is a complex tool that itself can take a semester or more to get
productive in. I know I myself tried for years to move to it and was only
able to after learning vim bindings pretty well, and starting to use
Spacemacs. Forcing students to use emacs, much less org - especially in
this day and age where students *will* ask online, and *will* get a
response of "no one actually uses that" - will probably meet with a ton of
resistance.

Thanks a lot Tim, I really appreciate you responding (as you said, it can
be discouraging to not get any response)

For the record, I just tried this simple example and it works

#+begin_src emacs-lisp :results silent
  (create-ob-npx :name "ob-nbb"
 :language "clojurescript"
 :npx-arguments "nbb")
#+end_src

#+begin_src clojurescript
  (prn (+ 1 2 3))
#+end_src

#+RESULTS:

Never pushed anything to MELPA before but will have to take a look at how
to do this.

Thoughts on this ob language generator

[George Mauer]

I had a need the other day to execute some typescript in an org document.
Now I know that there's an ob-typescript package but that doesn't quite
work the way I want and expects typescript to be installed globally (which
runs into a variety of versioning issues).

There is a better option available with the `npx` program (installed
alongside `npm`) which can install a package along with its dependencies
into a temporary sandbox and run its binaries.

I rewrote the typescript babel plugin to do this and then realized that
there was relatively little in it beyond variable and function names that
was typescript-specific. The exact same process can be used for anything
that has an interpreter up on npm. Coffeescript, mermaidjs, all sorts of
things.

So I made a macro. I'm interested what people here think:

Re: Utility of description lists

[George Mauer]

It is not quite true that it's just a way of formatting, there is a
semantic element to it as well where someone parsing your document
programmatically can now know that what you have is a list of terms paired
with their descriptions. In fact, when exporting to html you get a
description list
 which is one
of the most underused-yet-everyone-should-use-it-more html elements.

call blocks as a function from inside elisp code

[George Mauer]

Hi everyone,

I know that I can call a source block as a function in a header argument
such as :var, inside noweb annotations, or with a #+call: as described here
https://orgmode.org/manual/Evaluating-Code-Blocks.html

I am interested in going one step further though.

I have one emacs-lisp block that generates a list of python files which
mention a search term provided by a variable (eg
gim/get-file-list(search="_utilities") )

I have another code block written in python that given a python filename
will do some ast parsing to tell me some interesting facts about it (eg
#+call: gim/get-python-program-info(filename="foo/bar/some_module.py") )

What I would like to do is to chain the two together (ideally inside a code
block so I can dynamically format the output) so that I can get info on
*each* of the files produced by the first block.

So is there a way to do the equivalent of #+call:
gim/get-python-program-info(filename="foo/bar/some_module.py") from
*inside* an elisp code block? I am aware that I can call things via noweb,
but I'm trying to see if I can avoid that for several other reasons

Re: "Orgdown", the new name for the syntax of Org-mode

[George Mauer]

Agree with Joost. If I remember correctly, the "down" part of markdown was
meant as a play on words to indicate that, unlike a proper markup language,
markdown has a direction and a value system but no defined standard. Since
org is definitely not that why must the waters? Just go for clarity.

Cascading cookie counts

[George Mauer]

* Cascading Checkbox Cookie Counts
  I would like checkbox cookies to show the total of all cookies beneath
them regardless of hierarchy nesting.
  The code for ~org-update-checkbox-count~ is more complex than I expected
so before spending time digging into this, maybe someone here has a tip?

** This should show 3/5 [1/2]
   - [X] Done
   - [ ] Not Done
** Nesting level 1
   - [ ] Not Done
   - [X] Done
** Nesting level 2
*** Nesting level 2.1
- [X] Done

** Cookie data recursive doesn't seem to affect this
   My understanding is that there's a cookie data ~~ property
flag you can use. I assumed that's what this was for but it seems to not
affect things (I've tried both with and without the angle braces, but the
regex seems to imply braces which is odd)

Re: A requires/provides approach to linking source code blocks

[George Mauer]

In implementing an extension you might consider doing it as a generalized
form of what I did with ob-racket (https://github.com/togakangaroo/ob-racket
).

I think it is best to rely on the import/require/include mechanism of the
language you're using. Pretty much all of them support adjacent files. The
problem with code block execution is that it expands the block and writes
it to a temporary directory in a non-predictable location. If you want to
reference other blocks, you need them to *also* write into files in the
same folder.

What I do in ob-racket is support a header :adjacent-file which allows you
to pass in the name of another block and then writes it into the same
folder as the file to be executed with a predictable name (the name of the
block)

So something like this

  #+begin_src racket :adjacent-file stacker-reader-expander.rkt
#lang reader "./stacker-reader-expander.rkt"

Will make sure the block named `stacker-reader-expander.rkt` is written
into that same temporary directory with that same name. There's a few rough
edges but for the most part it works well. Would love to see someone take
this and generalize it into its own extension.

For anyone who has never tried it, I'll add that the open office formats

Re: appearance of list as results from evaluating code blocks

[George Mauer]

What about :results code
The default is a elisp code block so you get syntax coloring

Re: Using backticks for the inline code delimeter?

[George Mauer]

The point I'm making is that this is already the de-facto thing. People on
this email list do it, people in talking in irc and in forums do it. I
don't think it has so much to do with markdown documents as it does with
Slack, Discord, Teams, even google chat adopting that convention. All our
fingers are getting trained to backticks everywhere *except* org documents.
As those already have trained us to use this construction, it might be a
good idea to just swallow the pill.

I don't think there's much of a slippery slope here. Most popular chat
programs don't support making headings markdown-style for example, and even
if they did I don't see many people attempting to use that.

Trying to enumerate syntax that I feel falls squarely in this category I
come up with only a few

- lists with dashes, org supports that just fine
*bold text* with stars, again org already does this
`backtick code`, org doesn't handle this and actually uses the tilde as a
delimeter which is extra jarring since its a strikethrough in many chat apps

That's really it. You could maybe also argue
> gt for quotation - that would be be nice as we're used to it from email
as well, but I don't see people using it all that much

but that's really it as far as common usage right now. Sure that list might
grow as different usages become common, but I would hope org is not against
evolving in small and reasonable ways as the expectations of users shift.

Using backticks for the inline code delimeter?

[George Mauer]

Markdown uses backticks to denote inline code which should get special
(typically monospace) formatting, org uses the tilde character.

Now I know that org is not markdown, is far more powerful than markdown,
and is not (mostly) the same use cases as markdown. But this one use case
*does* overlap. And the backticks thing is becoming so ingrained that not
only do I reach for it all the time, but I've seen it crop up on this very
mailing list and even in some README.org documents.

I would like to submit that org consider adopting backticks as an alternate
way of denoting inline code.

Aside from any official movement, I would like to add this to my own files
- is there a straightforward way to extend the org parser to do this?

Re: How to get shell source blocks to read my profile?

[George Mauer]

I understand why you say that maxim but testing that this worked was the
first thing I did and it does work. I was surprised as well. I haven't
debugged all the way into the eval functions to see why this works but my
guess is that the authors were pretty smart about figuring out which
executable to invoke.

As for the problem I'm trying to solve, there isn't one exactly. This is
more me hacking on something I don't fully understand because it regularly
trips me up.

I do still wonder what would be the disadvantage of just configuring it to
do --login by default and doing all configuration in profile scripts. It
would be unconventional yes, but it would also make dynamic scoping of
environment variable effectively opt-in via --noprofile rather than opt-out
(which imo is how it should be). I would assume that uses extra resources
or risks improperly handling crashed processes, but I can't find anything
to that effect in the docs

Re: How to get shell source blocks to read my profile?

[George Mauer]

Thanks a lot! The interactive/non-interactive was indeed the core issue.
Extra frustrating because it seems like supplying `--rcfile` does nothing
if you *do* use `-c` but *don't* use `-i`...ah ad-hoc cli design.

As a general solution, I've found that adding this block in my org buffer
will make shell (which is zsh in my case) run in interactive mode for all
of these

* Local Variables :noexport:
  :PROPERTIES:
  :VISIBILITY: folded
  :END:
  local variables:
  shell-file-name: "/bin/zsh -i"
  end:

How to get shell source blocks to read my profile?

[George Mauer]

I am confused why no matter how I try to run shell commands they seem to be
missing variables exported in profiles.

I have added 3 variables to various startup scripts

  - ~./bash-profile~ :: ~export GIM_BASH_PROFILE="yes"~
  - ~./bashrc~ :: ~export GIM_BASHRC="yes"~
  - ~./zshrc~ :: ~export GIM_ZSHRC="yes"~

I am running emacs in GUI mode so I get why none of these are available
*directly* in emacs, so then I try

  #+begin_src shell :results list
env | grep GIM
  #+end_src

  #+RESULTS:

Ok that's kinda surprising, but I suppose it could be running ~/bin/zsh~
(that's my ~shell-file-name~) directly

what about

  #+begin_src shell :results list
bash -c env | grep GIM
  #+end_src

  #+RESULTS:

That's pretty surprising. I would have expected running it directly to
actually run my profile.

Shockingly

  #+begin_src shell :results list
bash --rcfile ~/.bashrc -c env | grep GIM
  #+end_src

  #+RESULTS:

That is *still* nothing!

Sanity is restored slightly when I run

  #+begin_src shell :results list
bash --login -c env | grep GIM
  #+end_src

which *does* indeed visit ~.bash_profile~ but only slightly.

What is going on, and is there a straightforward way in which I can get
shell block to read from a profile?

noweb expansion when eval and not tangle?

[George Mauer]

I would like noweb to expand during eval but *not* tangle. Is this possible?

I realize I can achieve the same effect with multiple code blocks but it
seems an odd asymmetry to not be able to do this directly.

Is it possible and just not documented?

Re: ist here a :post header arg for tangling?

[George Mauer]

So like I said, I would like to run some code to post-process files.
Nothing super-concrete, but a bunch of small use cases I've run into such as

- Running tests on every tangle
- Executing a code block in the same document and running tests after all
tangles
- Running a code-formatter such as prettierjs (or the python one which name
escapes me - autopep?) and potentially de-tangling back

I realize some of these things I could do with a file watcher, but not
really the ones that require modifying the document again

[George Mauer]

I'd like to run some code to post-process files after they are tangled. Is
there a header-arg for that?

Re: Emacs as an Org LSP server

[George Mauer]

I think maybe you might be thrown off by the word "server"? Lsp is just a
standardization of how an editor can do language-specific things. The fact
that standardization exists makes the whole thing pluggable by various
services. These typically run in a separate process - which is a good idea
anyways - on the same machine and the plugin just starts that prices and
communicated to it.

Typescript, c#, I think python, and JavaScript (and maybe Java?) plugins
already do this

Html export custom container with attribute

[George Mauer]

I know I can have a headline render to a custom container during export to
html with a property eg HTML_CONTAINER: details

But what If I want an attribute to set the state? Specifically I want the
container to be `` in some situation and just plain
`` in some others.

What are my options?

Thanks a lot,
George

Why are some headings html exported as lists while others aren’t?

[George Mauer]

I am practicing with org->html conversion by trying to export an html
resume.

I have the following

And the following .dir-locals.el

((org-mode . ((org-export-with-section-numbers . nil)
  (org-html-html5-fancy . 't)
  (org-export-with-toc . nil)
  (org-html-postamble . nil


When I export this to html the HTML_CONTAINER and HTML_CONTAINER_CLASS
properties are working for the Contact and my name and About headers, but
all the headers underneath Contact appear as `ul` with no classes.

It would seem that there's some sort of "level" beyond which heading are
not customizable.

Is that how it works? I'm not finding a variable I can override if it is.

Re: Remembrance Agents

[George Mauer]

As far as I know the only thing remotely like that is the org-roam buffer
when you are in a file managed by org-roam. This would be simply a linkable
list of other roam notes which reference the currently viewed note

So not exactly what you're looking for I suspect but a similarish concept

How to get a block’s contents by name

[George Mauer]

I'm trying to figure out how I could fetch the contents of another block by
name from an elisp script

I've seen `org-sbe` but I just want to get the block contents, (ideally
with noweb and vars filled in - just as it would be tangled if we were to
tangle it)

How do I do that?

Cannot load om while trying to load org

[George Mauer]

This might be a spacemacs-specific error, but maybe people here can help me
out?

I am getting the following error on org load
> (file-missing "Cannot open load file" "No such file or directory" "om")

(full stacktrace below)

Indeed, I get this:

> (require 'om)
> *** Eval error ***  Cannot open load file: No such file or directory, om

Yet `describe-package` shows that om *is* installed

```
om is a dependency package.

 Status: Installed in ‘om-20200927.1406/’ (unsigned).
Version: 20200927.1406

Very possible that I don't know what I'm doing here, but it seems like
`require` should absolutely work should it not?

Control where files are emitted during block eval

[George Mauer]

I would like to create a playground.org file inside my node project where I
will put bits of code that I'm playing with during development.

The problem is that when I actually evaluate a source block it gets written
into a temporary location that I do not control - I therefore cannot
`require` my project's node modules as they will not be found.

Is there a way to control the location the temp file is written? Maybe -
assuming it uses `with-temp-file` - a way to control its directory and file
name generation algorithm via a header?

Re: Can you automatically noweb include?

[George Mauer]

For what its worth, I maintain (well maintain is a big word when I'm also
probably the only person to use it) this fork of xchrishawk/ob-racket:
https://github.com/togakangaroo/ob-racket

It seems to have more features than the wallyqs one supporting :var headers.
I can look at how prologue support works in others and add it, but I also
am surprised that this is up to the plugin authors *at all*. As you pointed
out, that means that it can't possibly support noweb expansion

Can you automatically noweb include?

[George Mauer]

Use case:

I'm using ob-racket  but this
would apply just as well to a few other workflows I have with python or js.

I would like to write a helper function in a src block and then
automatically have access to it in other src blocks further down the
document. I don't really want a stateful session (nor does ob-racket
support sessions) so I essentially want the equivalent of automatically
including it everywhere so I don't have to type it out all the time (and
have it screw up syntax coloring/indentation).

Is this currently possible? Does anyone have any ideas for how to extend
things so it is?

Updates to ob-racket mode, code review request

[George Mauer]

I'm a big fan of using org mode to learn languages and have been using it
for Racket (sorry Dr Racket, I just love emacs too much). It's been mostly
fine and I've made a few patches to the [`ob-racket`](
https://github.com/xchrishawk/ob-racket) I've been using. Recently I've
started to move into the build-your-own-language parts of Racket and found
that ob-racket didn't support custom language directives. So [I modified it
to support them](https://github.com/togakangaroo/ob-racket).

I'm pretty new at elisp, so would anyone be willing to give me a code
review to make sure I didn't do anything completely stupid? [It is a single
not-too-large file](
https://github.com/togakangaroo/ob-racket/blob/master/ob-racket.el).

Also looking for opinions on whether this is helpful enough/good enough to
be worth pushing to melpa.

Get generators working in an src block?

[George Mauer]

I prefer to use source blocks for pretty much all my language learning.

I am trying to figure out generators in emacs-lisp but can't seem to run it
in a block.

I have

```
#+begin_src emacs-lisp :results output
  (setq lexical-binding t)
  (require 'generator)

  (iter-defun my-iter (x)
(let (val (iter-yield (1+ x)))
  (iter-yield (1+ val)))
-1)

  (let* ((it1 (my-iter 5))
 (it2 (my-itr 0)))
(print (iter-next it1))
(print (iter-next it1 8))
(print (iter-next it2 nil))
(condition-case x
(iter-next it1)
  (iter-end-of-sequence
   (print (cdr x)
#+end_src
```

But running that gives me

> executing Emacs-Lisp code block...
> cl--assertion-failed: Assertion failed: lexical-binding

something else is needed?

Bug: Export to html not working [9.3.7 (9.3.7-2-g706970-elpaplus @ /Users/gmauer/.emacs.d/elpa/develop/org-plus-contrib-20200608/)]

[George Mauer]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

 https://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org mailing list.


I wrote the following literate-programming style org file
https://github.com/togakangaroo/daily-programmer/blob/master/get-directories/README.org

When I run org-export-dispatch on this and export it to an html file it
creates a single file which - aside from the footer - contains only a
single letter `n` as contents

Re: Get Grades Done: the joys of Org's simple power

[George Mauer]

You know...I believe some people have gotten emacs running in browser...
You could do it by compiling it to wasm. So in theory you could create a
completely in-browser emacs which is optimized primarily for org mode usage.

Would be kind of an awesome thing for someone to tackle as it would greatly
increase the reach of org. Not easy though. Could probably be a whole
thesis project.

Not sure how well it would work with screen readers and other accessibility
tech though. That would be even more work

How to supply multiples of a custom src block header arg

[George Mauer]

It would seem that `:var` in src blocks gets special treatment.

I am hacking on ob-racket trying to add the ability to require from a
header (the `:results value` mode wraps everything in a `let` so you need
something special to put requires at the top level).

I do this

```
#+begin_src racket :require rebellion/collection/list :require
rebellion/streaming/transducer :var foo=1 :var bar=2
  (transduce (in-range 1 10)
 (folding + 0)
 #:into into-list)
#+end_src
```

Note there’s two `:var` headers and two custom `:require` headers

Yet when in my `org-babel-execute:racket` function I log `params`

```
(defun org-babel-execute:racket (body params)
  "Executes a Racket code block."
  (message "==params %s" params)
  ...
```

I get

```
==params ((:var foo . 1) (:var bar . 2) (:colname-names) (:rowname-names)
(:result-params replace) (:result-type . value) (:results . replace)
(:exports . code) (:session . none) (:cache . no) (:noweb . no) (:hlines .
no) (:tangle . no) (:lang . racket) (:require .
rebellion/streaming/transducer))
```

Note that both `:var` headers have corresponding cons cells but only the
last `:require` header does

What is causing this behavior and how would I modify it?

How to both export html and show the code?

[George Mauer]

I would like to both render html and show a source block for the rendered
html (I am aware of ob-browser, but I want this to be dynamic html content,
not an image)

I would have thought the following would work, but noweb returns an empty
string

Well, this is solvable with css is it not?

#+name: challenge-1-solution
#+begin_export html

  
  
#gradient-colors div {
  width: 400px;
  height: 200px;
  animation: gradient 5s infinite linear;
}
@keyframes gradient {
  0% {
background-color: hsl(0, 100%, 50%);
  }
  25% {
background-color: hsl(90, 100%, 50%);
  }
  50% {
background-color: hsl(180, 100%, 50%);
  }
  75% {
background-color: hsl(270, 100%, 50%);
  }
  100% {
background-color: hsl(360, 100%, 50%);
  }
}
  

#+end_export
#+begin_src html :eval no :exports code :noweb yes
  <>
#+end_src

How to get all headings from current location up to the root

[George Mauer]

I feel silly that I can’t figure this out but how do I get the current
heading, its parent, its parent parent, etc via elisp?

Improving Org Mode for VSCode - Thinking Aloud

[George Mauer]

With VSCode becoming ever-popular it seems like there might be some value
in getting org mode working there simply as a way of promoting org as an
excellent literate coding notebook.

VSCode already has a halfway decent org-mode but it doesn’t support
anything from Babel. I’m trying to think of relatively easy ways of adding
that ability. Here’s a thought: Most of babel that technically works
against the document itself, it doesn’t really need much document
integration with the editor. So could you get it working in vscode so long
as someone has a properly configured version of emacs installed locally?
“Evaluate/Export/etc” would just write the document, then use emacs to run
the appropriate commands on it and refresh the document view.

Of course features like the separate editor for src blocks and
folding #results would be nice too, but if the basics could work that would
be a huge win for org.

Any thoughts on the feasibility of this?

results block doesn't get replaced when doing :results raw

[George Mauer]

I've seen this happening a lot in a variety of modes. When I do `:results
raw`, on subsequent  evaluations, rather than replacing the results block,
it gets appended to.

This is almost never what I want. I remember seeing some use of `:results
raw replace` in some manual or another but that never really seems to work
for me.

Is there a property or something that can be set to always replace?

Re: Powershell scripting with org-babel

[George Mauer]

> Micro$loth WindBlows is a computer virus

Well that's mature and appropriate.

I recently did an implementation of `ob-pwsh` for supporting powershell
core (it assumes there’s a pwsh command available on PATH though thats
configurable with `org-babel-command:pws`). Here’s the link
https://github.com/togakangaroo/ob-pwsh. Instructions for installing are in
the README

It works ok and even supports variables but was a 3 hour hack job, plenty
of features missing. I hadn’t even announced it on this list before. The
code is pretty small though - under 60 loc if you want to contribute to it,
I’m game.

I also saw this a while ago but haven’t really dug in
https://old.reddit.com/r/emacs/comments/dkz0n1/babel_with_powershell/?st=k5jqc8es=b464c181

Oh, and powershell is awesome. It’s 2020, we *should* have a runtime in our
terminal (eshell somewhat does this and is pretty good because of it). One
of the things that would be really nice to do some day would be some sort
of conversion between powershell and lisp structures so that we could pass
structured data as hashes and lists between languages - not just strings.

Have :var reference a value

[George Mauer]

I'm playing around with learning racket in an org buffer and I have a bunch
of blocks that look like this

   #+begin_src racket :var value="abbracadaabra"
   ...do stuff with value...
   #+end_src


   #+begin_src racket :var value="abbracadaabra"
   ...do other stuff with value...
   #+end_src

Is there a way to move the "abbracadaabra" string into a single location so
that I can just pull the var from that? I know I can put it in a table or a
list, but how about into a single value?

Re: “Literate” python?

[George Mauer]

I've used noweb references to actually assemble what will be tangled all at
once. See how I did it here

.

The reason why the "incorrect" block is outdented is that tangle
automatically tries to guess indentation level. (Take that as a handwavy
thing - I don't know exactly how it does that nor how configurable it is)
The solution I've found is noweb - basically you *wouldn't* tangle any of
those blocks, but would create another non-evaluated or exportable block
that has noweb references to the above blocks and how you want them
arranged. *This* is the block you tangle.

I haven't yet figured out how, but it should be possible to automatically
configure things to run autopep8 after tangling - that would take care of
indentation issues.

Also I'm pretty sure there's no :weave header arg...at least I haven't seen
it used and can't find it documented anywhere.

Re: Org export to HTML with encrypted information ??

[George Mauer]

Basic "I'm not too worried about it" level of security: stick it on a
webserver using .htaccess to demand a password. Make that password halfway
decent.

Better option: export to PDF by either exporting to HTML or latex and then
using that system's PDF export. Keep both PDF and original in a folder on
Google drive or Dropbox that is shared only with those who need access. (No
password needed at all so you won't have someone compromising you with a
crap password)

Best option: same thing but store those files in a respected password
manager like 1password or keepass. Train your family to use the password
manager. Use it as a vault for all sorts of "just in case, they should
know" info.

In theory, you could even automate things to work on a deadman's switch.
Have a system that pings you via email, SMS, or another communications
mechanism weekly. If you don't respond within a few days, it automatically
shares the aforementioned files using gdrive, Dropbox, 1password, etc (not
email though - email is not secure)
