Source browsing and refactoring for C and Java

Notes on the Xref-Speller tools: how the cross-reference file is built, how to browse sources as hypertext and how to refactor safely.

~/xref-tech

$ xref --list articles

# six articles, pick one

$

ls languages/

Two languages, one cross-reference

C

Full pre-processing and parsing of K&R and ANSI sources - and how pre-processor constructs keep their original position.

Java

Browsing Java sources as linked hypertext: what changed, and what the tool deliberately kept.

man xref

$ refactor

Refactoring after Martin Fowler - applied to C through the tool's source-browsing features.

$ generate

How the cross-reference file is generated from pre-processed, parsed sources.

$ browse

Source browsing as hypertext: jumping between definitions and uses.

$ about

What a 'program' means here, and where XREF fits in the tool chain.
