Make symbols case match definition

The fglcomp compiler can make all symbol names match their definition exactly.

The fglcomp compiler provides the --fix-case option, to make all symbols match exactly the name used in the definition of the symbol.

Tip:

Before refactoring all sources with --fix-case, use the -Wcase option of fglcomp, to find how many symbols do not match their definition exactly. To force a compilation error, add the -Werror option.

By default, the modified source is written to the standard output stream (stdout). No output is produced, if no modification is required. To replace the orignal source file directly, add the --inplace option. With the --inplace option, fglcomp makes a copy of the original source, using the .4gl~ file extension.

In the next example, the variable custid in the LET instruction should use the same "UpperCamelCase" naming convention, as in its definition:

MAIN
    DEFINE CustId INTEGER
    LET custid = 998
END MAIN

To fix this code, use

fglcomp
--fix-case

$ fglcomp --fix-case main.4gl
MAIN
    DEFINE CustId INTEGER
    LET CustId = 998
END MAIN

To replace the original file directly, use the --inplace option:

$ fglcomp --fix-case --inplace main.4gl
