Feature Request: Highlight specific lines and/or line ranges

smerth commented 6 years ago

Hello, Thanks for such a great app. Typora is at the core of my daily workflow and I love it. I author md files that I pass to websites I have built or to an ebook authoring app. In both cases the md files are parsed and the code blocks are highlighted using prism.js

Prism has a feature called: Highlight specific lines and/or line ranges .

I can indicate which lines in a code block I want the reader to focus attention on by appending the lines the language specifier in the code block in the md file, for example...

```javascript{12-43}

wraps the lines 12 to 43 in a class I use to focus the reader on those lines within a code block

This will ensure that those lines get wrapped in a class that I can target with css to call them out to the readers attention.

Unfortunately this breaks the code highlighting in Typora...

If anything is appended to the language type specifier for the code block like {1, 25-27} Typora doesn't highlight the entire code block..

Can you implement this in Typora... Or, can you allow this kind of line specification in curly braces to follow the language specification for code blocks without breaking Typora highlighting?

Thanks, Smerth

I think this is what I am looking for also. If we can highlight in code fence that will be perfect

Just started using Typora and this is also the first thing I was searching for.

Hi, this is something I am also looking for. Would be great to be able to highlight text within a code block. Thanks

I look forward to it. I am using the prism highlighter with line highlight. If the typora has this feature, it would be great!!

I'd also find the ability to highlight within code fences very useful.

Just started using Typora, and it was the first feature I looked for. That would be great if you add it sooner.

If we can mark some code pieces in code fence. That will be a great feature !

Vote for this. Atom's Markdown Preview Enhanced has these feature supported.

```gas {.line-numbers, highlight=4}
targetFunc:
    stmdb   sp!, {r4-r12, lr}
    sub     sp, sp, #0x20
    add     r1, sp, #4
    str     r1, [sp, #8]
    ldr     r3, [sp, #8]
    ldr     r4, [sp, #0xc]
    add     sp, sp, #0x20
    ldmia   sp!, {r4-r12, pc}

Which yields the following result.
