Do not require space by the incrementation operator

[phoe]

Your reader macro, after collecting all the tokens, can iterate over all of them and check if any of them are of form FOO++ (same thing for ++FOO and --). If so, it can split that token into FOO and ++.

This should be enough to type the ++ operator in a more natural style - without any spaces between the variable name and the operator.

I see. I have thought only the reader splits and makes tokens.
Your suggestion is meaningful. I'll try to consider it. Thank you.

That is correct, the reader will see FOO++ as a single token. Nobody prevents you from adding a post-processing step though, that will accept raw input from the reader and split FOO++ into a pair of tokens that are FOO and ++ in the result.

Sorry, I am very late for responding.

I implemented a new pass for splitting token including ++, --, or unary *, &. (commit 7d87cea).
And I rewrote examples in README. The example of "Duff’s Device" now looks prettier.

Additionally, I plan to add some features in future:

• Extending this treatment for some operators; When I write C, I use !, ~, -> without spaces. I think they are good candidates.
• Trying to look local bindings using variable-information of CLtL2, because I want to use with-c-syntax in anywhere.

Thank for your suggestion!
