There are three important features that were in the initial design of D2 that have not been done and hold it back from 1.0: globs, imports, and vars. This release brings imports.
Imports open up a world of possibilities and works beautifully to modularize diagrams. See the new docs to try it out today.
As usual, many improvements and bug fixes accompany this release. D2 0.5 produces more legible diagrams by masking obstructions (e.g. arrow going through a label), has better error messages to guide you, is faster at certain tasks, and addresses many issues brought by community bug reports.
Features 🚀
- D2 files have the ability to import from other D2 files. See docs. #1371
sql_tablealternatively takes an array of constraints instead of being limited to a single one. Thanks @satoqz ! #1245
Improvements 🧹
- Use shape-specific sizing for grid containers #1294
- Grid diagrams support nested shapes or grid diagrams #1309
grid-gap,vertical-gap, andhorizontal-gapapply to padding on grid diagrams #1309- Watch mode browser uses an error favicon to easily indicate compiler errors. Thanks @sinyo-matu ! #1240
- Grid layout performance improved when there are many similarly sized shapes #1315
- Connections and labels are adjusted for shapes with
3dormultiple#1340 - Constraints in
sql_tablerender even if they have no matching abbreviation #1372 - Constraints in
sql_tablesheds their excessive letter-spacing and is padded from the end consistently #1372 - Duplicate image URLs in icons are only fetched once #1373
- In watch mode, images are cached by default across compiles. Can be disabled with flag
--img-cache=0. #1373 - Common invalid array separator
,usage in class arrays returns a helpful error message #1376 - Invalid
constraintusage is met with an error message, preventing a common mistake of omittingshape: sql_table#1379 - Connections no longer obscure outside labels #1381
- Container connections in
dagreare more balanced #1384 - Connections that go through shape labels are now masked translucently #1383
Bugfixes ⛑️
- Shadow is no longer cut off when
--padis 0. Thank you @LeonardsonCC ! #1326 - Fixes grid layout overwriting label placements for nested objects #1345
- Fixes fonts not rendering correctly on certain platforms. Thanks @mikeday for identifying the solution. #1356
- Fixes folders not rendering in animations (
--animate-interval) #1357 - Fixes panic using reserved keywords as containers #1358
- When multiple classes are change different attributes of arrowheads, they are
all applied instead of only the last one #1362 - Prevent empty block strings #1364
- Fixes
dagremis-aligning a nested shape's connection #1370 - Fixes a bug in grids sometimes putting a shape on the next row/column #1380
Breaking changes
@xyzis now reserved as a pattern for imports. If you previously had a key that started like that, it must either be renamed or quoted like"@xyz".- Likewise with
...@xyz(spread operator import)
