Spell Checking with cSpell
DitaCraft includes a pre-configured cSpell configuration with comprehensive DITA vocabulary to prevent false "unknown word" errors when using spell checkers.
Setup cSpell
Option 1: Automatic Setup (Recommended)
- Open Command Palette (
Ctrl+Shift+P/Cmd+Shift+P) - Type "DITA: Setup cSpell Configuration"
- Click the command
- DitaCraft will create a
.cspellrc.jsonfile in your workspace root with all DITA terminology pre-configured
Option 2: Manual Setup
- Copy the template
.cspellrc.jsonfrom the DitaCraft project repository - Place it in your workspace root folder
- The configuration includes:
- All DITA 1.3 elements (topic, titlealts, topicref, etc.)
- Common DITA attributes (href, conref, keyref, format, scope, etc.)
- Publishing terms (ditamap, bookmap, ditaval, etc.)
- Specialized configurations for
.dita,.ditamap,.bookmap, and.ditavalfiles
Why cSpell Configuration?
DITA includes many technical terms and element names (like titlealts, conref, keyref) that aren't recognized by standard spell checkers. The pre-configured .cspellrc.json prevents false "unknown word" warnings for these legitimate DITA terms while still catching actual spelling errors in your documentation content.
What's Included in the Configuration
The default cSpell configuration includes:
- DITA elements: topic, concept, task, reference, figure, table, section, and 100+ more
- DITA attributes: href, conref, keyref, conkeyref, format, scope, type, and more
- Map elements: ditamap, topicref, mapref, keydef, reltable, and more
- Bookmap elements: chapter, part, appendix, frontmatter, backmatter, and more
- Learning elements: learningBase, learningObject, learningContent, and more
- Specialized terms: ditaarch, xmlns, OASIS standards, and DITA-OT related terms

Workflows
Navigating Your Documentation Structure

.ditamapor.bookmapfile - Ctrl+Click (Cmd+Click on Mac) on any
hrefattribute value in<topicref>elements - The referenced topic file opens in a new tab
- Navigate back and forth between map and topics seamlessly
Example:
<map>
<topicref href="introduction.dita"/> <!-- Ctrl+Click opens introduction.dita -->
<topicref href="chapters/ch1.dita"/> <!-- Works with relative paths -->
<topicref href="overview.dita#intro"/> <!-- Handles fragment IDs -->
</map>
Publishing a Book
- Create bookmap:
DITA: Create New Bookmap - Create chapters:
DITA: Create New Topic(multiple times) - Edit bookmap to reference chapters
- Use Ctrl+Click navigation to quickly jump between bookmap and chapter files
- Validate:
Ctrl+Shift+V - Publish:
Ctrl+Shift+B→ Select format - Open output folder
Previewing Changes
- Open
.ditafile - Make edits
- Press
Ctrl+Shift+Hto preview - Preview auto-refreshes on save
- Toggle between source and preview

Known Limitations
Smart Navigation (v0.2.0)
The current implementation provides comprehensive navigation support. Minor limitations include:
Same-file Content References (
@conrefwith#) - e.g.,<ph conref="#v4.3/summary"/>- References starting with
#point to elements within the same file - Currently opens the file but doesn't scroll to the specific element
- References starting with
Conditional Key Definitions
- Keys with DITAVAL conditions may not be resolved correctly
- The key space builder uses the first definition found
External Key Scopes
- Keys defined in external key scopes are not yet supported
- Limited to keys within the workspace
What now works (NEW in v0.2.0):
- ✅
href="path/to/file.dita"- Direct file paths - ✅
href="file.dita#topic_id"- File paths with fragment identifiers - ✅
conref="file.dita#element_id"- Content references - ✅
keyref="key-name"- Key references resolved via key space - ✅
conkeyref="key-name/element"- Content key references - ✅ Automatic root map discovery and key space building
- ✅ Intelligent caching with 1-minute TTL
- ✅ File watcher debouncing (300ms) for performance

Troubleshooting
DITA-OT Not Found
Problem: Extension shows "DITA-OT not found"
Solution:
- Verify DITA-OT is installed
- Run "DITA: Configure DITA-OT Path" command
- Select DITA-OT installation directory
- Verify with "DITA: Validate Current File"
Validation Errors
Problem: Validation shows unexpected errors
Solution:
- Check XML syntax (closing tags, quotes, etc.)
- Verify DOCTYPE declaration
- Try switching validation engine:
"ditacraft.validationEngine": "built-in"
Publishing Fails
Problem: Publishing fails with error
Solution:
- Check DITA-OT logs in Output panel
- Verify output directory is writable
- Check for syntax errors in DITA file
- Try publishing with
--verboseflag:"ditacraft.ditaOtArgs": ["--verbose"]
Smart Navigation Not Working
Problem: Ctrl+Click on href attributes doesn't open files
Solution:
- Verify you're in a
.ditamapor.bookmapfile (check file extension in status bar) - Hover over the href value - it should be underlined if detected as a link
- Make sure you're clicking on the href value itself (e.g.,
introduction.dita), not the attribute namehref= - Check that the referenced file path is correct and file exists
- Try reloading VS Code window (
Ctrl+R/Cmd+Rin VS Code) - Verify extension is activated (look for "DitaCraft" in Extensions)
Example of correct usage:
<topicref href="introduction.dita"/>
^^^^^^^^^^^^^^^^^^^^
Ctrl+Click here (on the value)
Preview Not Showing
Problem: Preview panel is blank or shows error
Solution:
- Verify HTML5 output was generated
- Check output directory exists
- Look for JavaScript errors in Developer Tools
- Try republishing:
Ctrl+Shift+B→ HTML5
