Raising this out of this thread to not digress too much.

Should svgbob allow the ability to style nodes? It would be nice to be able to do it so that diagrams can be represented in text and still support colour. The ascii version of the diagram is not very readable with styling information included in each node. @ivanceras gave an example of using single letters to represent colour, but I foresee potential use cases for additional styling.

I've copied a bit of the post and edited it to see what it may look like:

 .---------.            .-----------.
( Alice {a} )  ---->   / Bob {b,c} /
 `---------'          '-----------'

 .---------.            .----------.
( Apple {a} )  ---->   / Ball {b} /
 `---------'          '----------'

# Legend:

a: { color: red }
b: { color: blue }
c: { opacity: 0.5 }

Also, what about people wanting to style lines? Maybe we leave that as a separate topic.

In some cases svgbob will take a letter inside a word and transform it to a symbol instead for letting it be a character that's part of the word; the examples I have seen where mainly with V, inside a word, be transformed in a down arrow.

svg bob could do a first pass and mark, with the help of a dictionary, the character that are not to be transformed, it should also be possible to input wors or whole dictionary of word to use if one has a technical name not part of the dictionary or uses a foreign language.

What

Words should be able to contain underscores and dashes.

E.g. these should be rendered as text, not lines: product_id, 2019-10-31, +10-15V. A good test case is the product table in demo.bob.

How

This PR achieves this by

• adding all alphanumeric characters to ascii_map.rs and subsequently
• checking whether the characters to the left or the right are alphanumeric.

Result

Old product table: New product table:

Improvements in product table:

• product_id and other headers
• dates
• serial keys, somewhat

Selected other improvements:

• circuits.bob, demo.bob: +10-15V
• long.bob: Derived_A, FS-Cache, e-mails, 1M-1Watt

There are no negative effects for the examples.

Possible further improvements

• Extend to (, ), /, :.
• Do something smarter than adding all letters and digits to ascii_map.rs.
• Add proper tests.

Hello !

Is there a way to display crossing diagonals ? Example:

------------.                
             \ .-------------
              \              
             / '------------>
------------'                

The diagonal crossing is incomplete. It would be nice to have access to X for that job:

------------.                
             \ .-------------
              X              
             / '------------>
------------'                

Thanks,

I would like to make a pandoc filter that does basically what spongedown does with ascii drawings. But I can't find how to properly pass a multiline string to svgbob through the command line. How is this done ?

On Windows, I have tried things like : echo "+--+\n| |\n+--+" | svgbob but the \n are kept as they are, and trying to pass the raw string from python actually ends the command in the middle of the string, effectively yielding an echo of the first line of the drawing.

What would be useful would be a method of returning a svg image from a request URL containing the source text, similar to SciWeavers site to return an image from Latex text (http://www.sciweavers.org/tex2img.php?eq=\sum_{i=1}^{n}x_{i}^{2}&bc=cornsilk&fc=black&im=jpg&fs=24&ff=arev).

Normally one CJK character equal two english character width, the following will be closed.

+----+
| 一 |
+----+

If the line contains escape qutoe, the CJK character seems need 3 english character spaces to get the shape closed.

I am using svgbob 0.3.2.

Sometime a char is treated as diagram char when it was intended to be word char.

Example 1:

co-edit
single-person

Is rendered as: The hyphen after o is treated as a horizontal line.

Example 2:

(some remark)

some text
(some remark)
some text

Is rendered as: The open bracket between lines is rendered as a diagram which the close bracket is still rendered as text.

Hi,

I notice a different rendering of the sequence:

                      .      \ \ '--- The::Latest
                     /|       \ \      \
 With::Some::fantasy  '        \ \      '---- The::Latest::Greatest
                     /|         \ \
         More::Stuff  '          \ '- I::Am::Running::Out::Of::Ideas
                     /|           \
         More::Stuff  '            \
                     /              '--- Last::One
         More::Stuff 

in svgbob and https://ivanceras.github.io/elm-examples/elm-bot-lines/

In a terminal the use of quote "'" rather than dot "." looks better in ASCII. Could you unify the rendering so both render the same way

If you think I am picky and have an hawk eye, it's because I have drawn most of the example you use in the old version and they grabbed my eye today when I saw this project for the first time.

I think I may steal from you one or two stencils, I like the circles rendering, in fact I like this project very much.

Hi there! Awesome project. I wanted to ask if it is possible to somehow tell renderer that "this character is just text"? I am trying to render Ruby's object diagram from the official book:

                             +---------+             +-...

                 |       |   |         |        |    |
                 |    Module-|---------|--->(Module)-|-...
                 |       ^   |         |        ^    |
                 |       |   |         |        |    |
                 |     Class-|---------|---->(Class)-|-...
                 |       ^   |         |        ^    |
                 |       +---+         |        +----+
                 |                     |
    obj--->OtherClass---------->(OtherClass)-----------...

...and the SvgBobRus understands it pretty well, but replaces most of the "O"s with special symbols (note also it can't guess two arrows under the "Class" at the bottom):

Problem

With using rsvglib(as rsvg-convert) on Mac, conversion is not great; output is dropping "lines". I am not sure this is rsvglib matter or svgbob.

Conditions

• MacOS
• svgbob 0.3.1
• rsvg-convert version 2.40.16

Hey, just stumbled over this and it looks great! Wondering if one can change the color of the text easily. As far as I understood the configuration of a class like {foo} is applied to the shape. Could there be something like {text:foo} to be able to set color for the text?

Thanks a ton and feel free to close if not a good question (or I was simply to blind to figure things out!).

Here is a minimal example:

-- "(A)"

which gives

And this is a greater example:

                 o--------------o------o "(A)"
                /
    "(E)" o----o
                        o
                        |
                        | "(M)"


                                o------o "(A)"

To easier the trial, It would be nice to have a docker image. language-independent docker imege makes it much easier to use with CI. (e.g. gitlab, jenkins)

For users unfamiliar in Rust, getting started with svgbob takes a bit of work.

Until an official image registry is created, the following unofficial image registry has been prepared. If possible, an official image registry would be better.

Hi,

I've tried to fill a triangle, but it does not work.

This is my testcase:

+---+ +-----+ + +---------+ +
|{r}|  \{r}/ / \ \       / / \
+---+   \ / /{r}\ \ {r} / /   \
         + +-----+ \   / / {r} \
+-----+             \ / /       \
|     |              + +---------+
| {r} |
|     |
+-----+

# Legend:
r = {
    fill: red;
}

Would it be possible to extend the syntax to draw an arc?

        +
       / \            "This would draw a sharp corner"
      /   v

        .
       / \            "This would dar an arc (a dot at the point where edges meet)"
      /   v

        .-.
       /   \          "This is the current way to draw something like an arc"
      /     v
