Org user who relies heavily on the org-pretty-entities feature to display portions of equations and chemical formulas.
Recently, I created a custom dictionary for the purpose of using it with auto-complete.el and popup.el. I was curious if there is an existing Solution
to display UTF-8 characters in the auto-complete popup window that mimics the functionality of org-pretty-entities? If not, how could something
similar be accomplished? Thanks in advance.
Bonus Points:
I have dozens of formulas stored under ac-dictionary-files that utilize subscripts; E.g:
H_{2}O
H_{2}SO_{3}
H_{2}PO_{4}^{-}
Upon typing H_ the complete list of those that begin with H are shown (and will complete successfully), however, typing the opening bracket { causes the list to list to close and completion to fail.
Some of the entries ("H_" for example) have such a numerous amount of completions it would take more key strokes (repeatedly pressing the TAB key)
than to type the formula itself. What can be changed to enable the use and/or recognition of the { } characters by prediction?

In TeX-latex-mode under Emacs (26.1) using the reftex minor mode,
When pressing C-c (, the command reftex-label (found in reftex-mode-map, from reftex-ref.el) gives pretty good suggestions of label according to context for sections (with the default value of reftex-insert-label-flags).
When pressing C-c C-s, the command LaTeX-section (found in LaTeX-mode-map, defined in latex.el) offers to enter a label for the section, with no suggestion (other than a prefix based on the level of the section, which is useful but much less than the one based on the title section offered by reftex-label).
How can one configure LaTeX-section to make the same suggestions as reftex-label for sections?
The hook LaTeX-section-hook along with the variable LaTeX-section-label would seem the right candidate for that purpose, but the documentation states that
Some LaTeX packages (such as fancyref) look at the prefix to
generate some text around cross-references automatically. When using
those packages, you should not change this variable.
for one, I assume that reftex is one of such packages, and second, I was expecting to be able to give a function inside a hook, not a list of prefixes, I wonder if I misunderstood what a hook is?
I think that one would "just" need to get LaTeX-section to abstain from offering a label and to call the function reftex-label immediately after each LaTeX-section call, but if it is not LaTeX-section-hook, I do not know which one it could be?
Before starting programming something which could involve stuff as complicated as refactoring both latex.el and reftex-ref.el, I thought I would ask in case I was missing an easier solution!!!
I can't seem to find if there's a way to do it.
I use VScode for writing markdown text. I love the intellisense/autocomplete which builds my word lists and helps me write faster. The one thing I wish I could change is for the autocomplete word lists to show up AFTER I've typed a certain number of characters.
For e.g., let's say I really want the word "guarding"
I'd like the popup only after I've typed guar rather than at g, and then u, etc. This way, I'm utilizing it only for longer words. The popup for every letter from the beginning is kind of annoying.
Is there a way to do it? (I seem to be able to control the delay when to popup,
In VSCode, when you place cursor inside a symbol (variables, functions, etc), all occurrence of the same symbol will be highlighted.
This feature is somewhat useful but annoying as well. Even I can make it less obtrusive by customizing the color theme in settings.json, it will suppress the selection highlighting when you select a variable by double clicking it with mouse cursor.
I've learned that I can completely disable this feature by adding "editor.occurrencesHighlight":false in settings.json, but this feature is still useful because it can label occurrences of a symbol with different color, to represent read/write status of each occurrence.
So my question is: is there any way to disable the automatic semantic matching feature, and only enable it manually with keyboard shortcuts or commands ?
If you only need textual matches, you can select some text use the Select all occurrences of find match command. This will select every occurrence of the selected text in the current document (and also create a cursor at it)
For symbol based information, try using the Find all references or Peek references commands. The flow is different but it gives the same information.
Alternatively, use an extension like this one to create a keyboard shortcut that toggles editor.occurrencesHighlight
Having trouble finding a way to do this, maybe it is not even possible?
In my case, for testing flow of if-statements/user-interaction, am temporarily adding 40 lines of console.log('trigger-fired-1'); throughout our code.
However, to tell them apart would like each to end with a different number, so in this case, numbers one to forty like so:
In the screen recorded gif, to replicate what I am going for, all I did was copy/paste the numbers one to nine. What I really would like is a shortcut key to generate those numbers at the end for me to eliminate that step of typing out each unique number.
Am primarily coding in Visual Studio Code or Sublime Text, and in some cases shortcuts are similar, or at least have same support but for different shortcut keys.
There are a few extensions that allow you to do this:
Text Pastry
Increment Selection
NumberMonger
For Sublime Text, the solution to this problem is the internal Arithmetic command. Something similar may or may not be available in VS Code (possibly with an extension of some sort) but I'm not familiar enough with it to say for sure.
This command allows you to provide an expression of some sort to apply to all of the cursor locations and/or selected text.
By way of demonstration, here's the example you outlined above:
The expression you provide is evaluated once for every selection/caret in the buffer at the time, and the result of the expression is inserted into the buffer (or in the case of selected text, it replaces the selection). Note also that when you invoke this command from the input panel (as in the screen recording) the panel shows you a preview of what the expression output is going to be.
The special variable i references the selection number; selections are numbered starting at 0, so the expression i + 1 has the effect of inserting the selection numbers starting at 1 instead of 0.
The special variable x refers to the text in a particular selection instead. That allows you to select some text and then transform it based on your expression. An example would be to use x * 2 immediately after the above example (make sure all of the selections are still present and wrapping the numbers) to double everything.
You can use both variables at once if you like, as well as anything in the Python math library, for example math.sqrt(i) if you want some really esoteric logs.
The example above shows the command being selected from the command palette interactively, where the expression automatically defaults to the one that you want for your example (i + 1).
If you want to have this as a key binding, you can bind a key to the arithmetic command and provide the expression directly. For example:
{
"keys": ["super+a"],
"command": "arithmetic",
"args": {
"expr": "i+1"
},
},
Try this one ...
its not like sublime
but works g

When using "change all occurences" in VS Code, it will just search the whole file for matches and change them. Is there a similar feature doing the same thing, but limiting it to function or block scope?
Let's take an example where I would need that: I'm having a React file with several components and want to refactor a class component to a functional component, so I'm changing all occurences of this.props to props. However, I obviously don't want to change all the other class components as well that are supposed to stay class components. :-)
This seems like such a standard use case, but I'm not able to find it anywhere in VS Code. If it's not possible (yet, or for some good reasons) is there another way to achieve what I'm trying to do?
Check out the 'Add Selection To Next Find Match' functionality. It allows you to highlight the first occurrence you'd like to change, then using a keyboard shortcut, highlight the next occurrence and so on until you've selected all the instances you want to change. When all to-be-changed occurrences are selected, you can edit the selected text normally. Just remember to hit the escape key a couple times after editing to return to a single cursor!
Here are the keybindings for the command, it's Cmd+d on Mac:
https://code.visualstudio.com/docs/getstarted/keybindings
I find it very useful when renaming variables, there's also a shortcut to skip occurrences (Cmd+k Cmd+d) in case there is text you don't want to change in between.
