indent(1): add regression test cases These examples show expected behavior of indent(1). They are meant to be used together with a regression test mechanism, either Kyua, a Makefile or perhaps something else. The mechanism should in essence do this: indent -P${test}.pro < ${test}.0 > ${test}.0.run and compare ${test}.0.stdout to ${test}.0.run. If the files differ or the exit status isn't 0, the test failed. * ${test}.pro is an indent(1) profile: a list of options passed through a file. The program doesn't complain if the file doesn't exist. * ${test}.0 is a C source file which acts as input for indent(1). It doesn't have to have any particular formatting, since it's the output that matters. * ${test}.0.stdout contains expected output. It doesn't have to be formatted in Kernel Normal Form as the point of the tests is to check for regressions in the program and not to check that it always produces KNF.

indent(1): rewrite the integer/floating constant scanning part of lexi.c Remove procedural code that did the scanning, which was faulty and didn't support complex constants such as 0x1p-61. Replace it with a finite state machine expressed as a transition table. The table was rewritten by hand from lx's output, given parts of grammar expressed as regular expressions. lx is Katherine Flavel's lexer generator, currently available at https://github.com/katef/libfsm and the parts of grammar were taken from http://quut.com/c/ANSI-C-grammar-l-2011.html and extended to support binary integer constants which are a popular GCC extension.

indent(1): bug fix after r336333 The bug was that isalnum() is not exactly equivalent to previous code which also allowed characters "$" and "_", so check for those explicitly. Reported by: tuexen@ 2018-08-15 18:19:45 +00:00			`x._y = 5;`
