(tw5) howto display c source code syntax highlighted in a scroll box with line numbers

[ch]

hi,

i started to use tw5 running on node.js to evaluate it as a wiki containing information about software development, for example:

1. links, like howtos, man pages, etc.

2. documents, like style guides, protocols, etc.

3. c source code examples, for educational purposes

it was pretty easy to manage point 1 and 2 above, but for point 3... i'am clueless.

basically, i want the following:

- create a tiddler which contain the raw c source code as plain text, then utilizing a new tiddler (transclude the source code tiddler...?) which can display the c source code, like this:

https://codemirror.net/demo/marker.html

i don't want to replace the built-in tw editor with codemirror (not yet) - i only want to utilizing the "viewing features" of codemirror.

- how do i accomplish that?

please note that i have no experience about the codemirror plugin, so a detailed step-by-step guide is highly appreciated.

kindly,

christian

ps. clicking the line-number gutter to add or remove 'breakpoints' - is a nice codemirror feature, which i also want...

Woudl it be enough to merely put the code within triple backticks

```

like this

```

I.e

empty line (!)

triple backticks on its own line

content

triple backticks on its own line

Hi ch

Have you tried the highlight plugin? It provides syntax highlighting for code blocks:

hi jeremy,

sadly, the highlight plugin doesn't support line numbers:

http://highlightjs.readthedocs.org/en/latest/line-numbers.html

codemirror seems to support all features i want:

1. syntax highlight

2. line numbers

3. display the c source code in a scroll box

4. mark/unmark a line by a little dot (codemirror call it "breakpoint")

https://codemirror.net/demo/marker.html

...but, i don't know how to use it with tw

kindly,

christan

Hi ch

sadly, the highlight plugin doesn't support line numbers:

You may be able to adapt this technique to use CSS to add line numbers:

https://gist.github.com/potch/1243028

> create a tiddler which contain the raw c source code as plain text, then utilizing a new tiddler (transclude the source code tiddler...?) which can display the c source code, like this:

You should be able to do something like this:

<$edit-text tiddler="my code tiddler" tag="textarea"/>

With the codemirror plugin installed, the textarea will be replaced by a full codemirror instance. But, it won't be read-only, so it would be very easy to accidentally corrupt one of your code samples

> i don't want to replace the built-in tw editor with codemirror (not yet) - i only want to utilizing the "viewing features" of codemirror.

The TW5 plugin for codemirror doesn't support being used in that way at the moment.

Best wishes

Jeremy.
