- casefold.c
- This is a perhaps silly utility that can be used to convert all parts of a
- file that are not in strings and not parts of comments to lower case. It has
- a list of exceptions for words that should NOT be folded to lower case.
- Its purpose is to make it possible to finalize the adaptation of Reduce
- from its original upper-case-only world to one where eventually we can
- make the system case sensitive.
- Anybody offended by the changes it has made to their code may either edit
- their files back to the state they want manually or they may add the mixed
- case words that matter to them to the list here and use this to apply
- changes systematically. In most cases where package maintainers had used
- mixed case at all I found multiple instances where they had not been
- consistent in its use.
- A harder issue is competing modules that use the same name but where there
- is disagreement as to the best case to use. Especially for local variables
- people ought really to be able to use whatever capitalization they like
- within their own package - but for simplicity I will apply global adjustments.
- The change I made that perhaps led me to need to alter most odd files was
- making the fully spelt out word COMMENT always appear in upper case in
- source files. This led to the need to adjust many log files. Note that
- "comment" and "Comment" will still be treated as introducing a comment
- if Reduce input has case-folding enabled. I believed that the bold word
- COMMENT was a better thing to standardise on than its lower case varient.
- When initially building this I will avoid processing anything in the redlog
- directory even though there are inconsistencies there so that the relevant
- authors can fix things up be hand! But otherwise I go something like
- for x in packages/*/*.red packages/*/*.tst
- do
- ./casefold $x
- done
- to standardise the bulk of Reduce. I then need to check and review all
- the .rlg files where they echo input that has been subjec to case change.
- I prefer to edit those individually as that helps ensure I have really
- considred log-file changes...
