v0.6.3

D2 0.6.3 allows you to make your own and customize existing D2 themes. Here's an example with some random color codes.

See docs

Playground link

Features 🚀

• Themes can be customized via d2-config vars. #1777

Improvements 🧹

• Icons can be added for special objects (sql_table, class, code, markdown, latex). #1774

Bugfixes ⛑️

• Fix importing files that override an existing value with an array. #1762
• Fixes missing unfilled triangle arrowheads when sketch flag is on. #1763
• Fixes a bug where the render target could be incorrect if the target path contains "index". #1764
• Fixes ELK layout with outside labels/icons. #1776
• Fixes a bug where an edge could become disconnected with dagre layout and direction right. #1778

v0.6.2

D2 0.6.2 makes grid diagrams significantly more powerful. Namely, connections can now be made from grid elements to other grid elements. This enables diagrams like the following.

Source code

Playground link

Credit: this diagram is based off of a manually-drawn one from a blog post

In addition, another significant feature is that using the ELK layout engine will now route SQL diagrams to their exact columns.

Playground link

Note that all previous playground links will be broken given the encoding change. The encoding before 0.6.2 used the keyword set as compression dictionary, but it no longer does, so this will be the last time playground links break.

Features 🚀

• ELK routes sql_table edges to the exact columns (ty @landmaj) #1681
• Unfilled triangle arrowhead is available. #1711
• Grid containers customize label positions. #1715
• A single board from a multi-board diagram can be rendered with --target flag. #1725

Improvements 🧹

• Grid cells can contain nested edges #1629
• Edges can go across constant nears, sequence diagrams, and grids, including nested ones. #1631
• All vars defined in a scope are accessible everywhere in that scope, i.e., an object can use a var defined after itself. #1695
• Encoding API switches to standard zlib encoding so that decoding doesn't depend on source. #1709
• currentcolor is accepted as a color option to inherit parent colors. (ty @hboomsma) #1700
• Grid containers can be sized with width/height even when using a layout plugin without that feature. #1731
• Watch mode watches for changes in both the input file and imported files #1720

Bugfixes ⛑️

• Fixes a bug calculating grid height with only grid-rows and different horizontal-gap and vertical-gap values. #1646
• Grid layout accounts for each cell's outside labels and icons #1624
• Grid layout accounts for labels wider or taller than the shape and fixes default label positions for image grid cells. #1670
• Fixes a panic with a spread substitution in a glob map #1643
• Fixes use of null in sql_table constraints (ty @landmaj) #1660
• Fixes ELK growing shapes with width/height set #1679
• Adds a compiler error when accidentally using an arrowhead on a shape #1686
• Correctly reports errors from invalid values set by globs. #1691
• Fixes panic when spread substitution referenced a nonexistant var. #1695
• Fixes incorrect appendix icon numbering. #1704
• Fixes crash when using --watch and navigating to an invalid board path #1693
• Fixes edge case where nested edge globs were creating excess shapes #1713
• Fixes a panic with a connection to a grid cell that is a container in TALA #1729
• Fixes incorrect grid cell positioning when the grid has a shape set and fixes content sometimes escaping circle shapes. #1734
• Fixes content sometimes escaping cloud shapes. #1736
• Fixes panic using a glob filter (e.g. &a) outside globs. #1748
• Fixes glob keys with import values (e.g. user*: @lib/user). #1755

v0.6.1

The globs feature underwent a major rewrite and is now almost finalized.

Before

Previously, globs would evaluate once on all the shapes and connections declared above it. So if you wanted to set everything red, you had to add the line at the bottom.

x
y

*.style.fill: red

Now

*.style.fill: red

x
y

We still have one more release in 0.6 series to add filters to globs, so stay tuned.

You might also be interested to know that grid cells can now have connections between them! Source code for this diagram here.

Features 🚀

• UTF-16 files are automatically detected and supported #1525
• Grid diagrams can now have simple connections between top-level cells #1586

Improvements 🧹

• Globs are lazily-evaluated #1552
• Latex blocks includes Mathjax's ASM extension #1544
• font-color works on Markdown #1546
• font-color works on arrowheads #1582
• CLI failure message includes input path #1617

Bugfixes ⛑️

• d2 fmt formats all files passed as arguments rather than just the first non-formatted (thank you @maxbrunet) #1523
• Fixes Markdown cropping last element in mixed-element blocks (e.g. em and strong) #1543
• Adds compiler error for non-blockstring empty labels #1590
• Prevents multiple constant nears overlapping in some cases #1591
• Fixes crash from empty nested grid #1594
• d2fmt with variable substitution mid-string is formatted correctly #1611
• Fixes certain shape IDs not working with dagre #1610
• Fixes font-size adjustments missing from rendered code shape #1614

v0.6.0

D2 v0.6 introduces variable substitutions and globs. These two were the last of the features planned in the initial designs for D2, and v1 is now very close!

The power of variables and globs in a programming language need no introduction, so here's two minimal examples to get started:

Variables:

vars: {
  color: aquamarine
}

x.style.fill: ${color}

Globs:

x
y
z

*.style.fill: aquamarine

Both are live on D2 Playground so give it a try! Looking forward to your issues and iterating

Layout capability also takes a subtle but important step forward: you can now customize the position of labels and icons.

Features 🚀

• Variables and substitutions are implemented. See docs. #1473
• Configure timeout value with D2_TIMEOUT env var #1392
• Scale renders and disable fit to screen with --scale flag #1413
• null keyword can be used to un-declare. See docs #1446
• Develop multi-board diagrams in watch mode (links to layers/scenarios/steps work in --watch) #1503
• Glob patterns have been implemented. See docs. #1479

Improvements 🧹

• Display version on CLI help invocation #1400
• Improved readability of connection labels when they overlap another connection #447
• Error message when shape is given a composite #1415
• Improved rendering and text measurement for code shapes #1425
• The autoformatter moves board declarations to the bottom of its scope #1424
• All font styles in sketch mode use a consistent font-family #1463
• Tooltip and link icons are positioned on shape border #1466
• Tooltip and link icons are always rendered over shapes #1467
• Boards with no objects are considered folders #1504
• DEBUG environment variable ignored if set incorrectly #1505

Bugfixes ⛑️
