GraphViz is a brilliant vendor-independent way of creating graphs and having them render into multiple formats such as SVG.

We can achieve stuff like this:

Just managed to map an #SBT project to an #SVG diagram. Clicking a node takes you to the project folder. https://t.co/IKr8eMkogp pic.twitter.com/9btcMAdKzk

Two options:

Render on the client-side

Can use Viz-JS (GitHub).

Very easy to use:

<script src="https://cdnjs.cloudflare.com/ajax/libs/viz.js/1.8.0/viz-lite.js"
    integrity="sha256-lLBbzF3IYSscIpBw/KgKjF1dDWMQdz1RWZnEdnNSDxA=" crossorigin="anonymous"></script>

    <script type="text/javascript">
    document.querySelector("#target").innerHTML = Viz(dotString, {format: "svg"});
    flw.innerHTML = image;
</script>
            
            

Render on the server-side

nidi3/graphviz-java

More powerful, can do XSL transforms, etc, etc, before serving SVG

Specific library however uses a V8 layer which seemed unstable to me.

Hub @ GitHub

Very useful utility, can just type hub push for example.

Scale stuff

Begin by using the non-scalable thing.

Then don't forget to scale.

These are just some ideas, non-committal I am.

Execute XSLT in one line

Using Saxon and Coursier

coursier launch net.sf.saxon:Saxon-HE:9.7.0-18 --main net.sf.saxon.Transform -- -s:source -xsl:stylesheet -o:output

Very useful when you want to run an XSLT transform..

Convert BPMN to SVG via command line

Not very pretty at all but could be improved with a better XSLT sheet. Way better than manual clicking:

$ wget https://raw.githubusercontent.com/trevershick/example-bpmn-dot-render/a1c1287bf19b1e1310cbbcfd37e767e71d651812/src/main/resources/xsl/bpmn.dot.xsl
$ coursier launch net.sf.saxon:Saxon-HE:9.7.0-18 --main net.sf.saxon.Transform -- -s:diagram.bpmn -xsl:bpmn.dot.xsl -o:diagram.dot
$ dot -Tsvg -o diagram.svg diagram.dot

I also filed an issue on bpmn-js.

Identity XSLT transform

wget -O test.xsl 'https://git.io/vHnat'

Also used the git.io Link Shortener for this.

Split a Git repository

Suppose you now want to split away a project but keep the commit history in Git.

$ git filter-branch --tree-filter 'mkdir new-repo; mv x y z new-repo || true' HEAD
...
$ git filter-branch --prune-empty -f --subdirectory-filter new-repo -- --all

Why does software take so long?

When a non-techie asks you why you take so long to get the thing done, this is what you tell them. #softwarehttps://t.co/dpB156iqpv

BlueGriffon Entity conversions

BlueGriffon converts entities to their direct characters, which then don't render.

To fix this, go to 'Preferences' > 'Source' > 'Serialization' > 'Output the following characters as entities' > 'All HTML4 special characters'.

JSON array to TSV?

Yep, doable with jq. Useful when you want to process data with CLI tools more easily.

Example:

curl -s 'https://actionfps.com/players/?format=json' | jq -r '.[] | [.id, .nickname.nickname] | @tsv'

#json array to #tsv with #jq: `curl -s 'https://t.co/NbmkSBPzSz' | jq -r '.[] | [.id, .nickname.nickname] | @tsv'` so nice.
