feature: Markdown-indemt-mode like org indent mode

[printfdebugging]

Is your feature request related to a problem? Please describe.

So I very much like the idea of this plugin, as markdown is a widely used format, but I find it very ugly when the concealing toggles for the whole file when changing b/w insert/normal modes. Maybe for one line would be fine.

Emacs has org-indent-mode, where each heading indents everything else by 2 spaces under it (other then same level headings). This way the document is formatted really nicely. Is it possible? I see we currently have left_padding for the code blocks, which doesn't let the cursor move any further. Maybe that can be extended similar to org-indent-mode.

I would love to have everything in markup. At max just the current line be shown as raw markdown. Is it possible?

If we have all these, then this plugin paired with mdeval will make up for a really great "standard" alternative for org-mode/other note taking apps. Neorg fits my needs, but it's not a widely used standard yet, and most static site generators use markdown.

Set win_options -> conceallevel -> default to 0, something like:

require('render-markdown').setup({
    win_options = { conceallevel = { default = 0 } },
})

See :h 'conceallevel' for more details on the values.

The concealcursor value we set (also in win_options) is what will allow concealing to only toggle for the current line.

You can change the modes that toggle concealing under the cursor by setting an appropriate concealcursor value, see :h 'concealcursor'.

More details on win_options in the Wiki here.

I can take a look into this, but my first thought is this would not be feesible. Mostly because the indenting would need to capture all block elements and indent them appropriately. Currently the plugin queries for a set of specific elements and modifies them. Applying something to all block children would be a pretty different thing to anything that currently exists. Depending on how much I like any solution I come up with will follow up and let you know.

Do you have a concrete description of what org indent mode indents exactly?

Is it every element under a heading including nested headings?

[printfdebugging]

Yes, all the elements including the codeblock, the paragraph, the lists. As if the left margin has been shifted as per the top level heading (toplevel in relative terms). Like every h2 and following one will be under h1 and 3 under 2 and so on.

# Heading 1
  ## Heading 2
    content for heading 2 
    - list item 1
    - list item 2
    ```cpp
    // comment here
    ```
# Heading 3
  content for heading 3

https://explog.in/static/images/org-indent-mode.png the left one is the org indent mode here. (this is an image from the internet.) Since you were able to do it for the codeblock, would it be hard for the rest? I mean it looks cool, gives the document a nice structure.

[MeanderingProgrammer]

I don't know about looks cool, but I can see why people would like it. Even in the example image whoever created it prefers only the headings to be indented over.

My personal preference it to stay close to the underlying buffer text to avoid large shifts in text when editing, but I don't mind providing the capability for others to use, hence all the padding options.

The short answer is this is either a really easy change or a nearly impossible one. It's easy if I can get everything within a heading section and apply an indent across all the lines. If I need to individually handle all node types and the potential ways they can be nested then it becomes nearly impossible.

[MeanderingProgrammer]

The section nodes made this not too bad, added some level of support here: 277ae65

This is an opt-in feature, to enable it:

require('render-markdown').setup({
    indent = { enabled = true },
})

This is great! Thank You!

[printfdebugging]

            require('render-markdown').setup({
                indent = {
                    enabled = true,
                    per_level = 2;
                },
                win_options = {
                    conceallevel = {
                        default = 0,
                    },
                    concealcursor = {
                        default = 'nvic',
                        rendered = 'nvic',
                    },
                },
            })

this is how it looks like. still I am getting the toggling when switching between normal and insert modes (for the whole file, instead of one line). I am doing it wrong probably.

[MeanderingProgrammer]

Try this:

win_options = {
    conceallevel = { default = 3 },
    concealcursor = { default = '' },
},

[printfdebugging]

Here's the problem., and it still pesists. as you see when I go into insert mode, all the concealing goes away.
