indent

description

Indent script for SAS. The algorithm is supposed to be rather tolerable. Examples of the indenting results are shown as following: 1. For data step/proc sections, the script can properly indent with or without the closing run/quit statements.    (SAS does not require explicit closing statements for data step/proc sections.)    data female;       set total; where gender = 0;    data male;       set total; where gender = 1;    run;    proc sort data = new; by gender;    proc freq data = new;       table gender / missing;    endsas; 2. The script can also recognize which procedure supports run-processing and indent accordingly.    proc reg;       model y = x1-x5;    run;       model y = x1-x10;    run;    quit;       3. The indentation is properly managed when mixed with macros.    (Nesting macro is evil. Don't do it)    %macro test();       data new;          set old; where age >= 18;          format gender gender.;       proc freq;          table gender;    %mend; 4. Logic expressions.    data a;       set b; where age >= 18;       if numtx = 1 and not (pid > 0 and dcitag in (1, 2)) then strata = 3;       else if pid > 0 then do;          if dcitag in (1, 2) then do;             strata = 1; dcitype = 1;          end;          else if dcipsh1 = 1 then do;             strata = 1; dcitype = 3;          end;          else if numtx > 1 then strata = 2;       end;       else do;          if dcitag2 in (1, 2) then do; strata = 1; dcitype = 2; end;          else if dcipsh1 = 1 then do; strata = 1; dcitype = 3; end;          else if pid < 0 and dcipsh1 ~= 1 and numtx > 1 then strata = 2;       end;    run; Please also check out my SAS syntax script: http://vim.sourceforge.net/scripts/script.php?script_id=3522

sas.vim	3.0.1	2017-03-13	7.0	Zhenhuan Hu	Fix an issue in indenting macro %end.
sas.vim	3.0.0	2017-03-10	7.0	Zhenhuan Hu	Support proper indentation for run-processing procedures.
sas.vim	2.2	2016-08-09	7.0	Zhenhuan Hu	Change the behavior how ENDSAS is indented. Now it indents at the same level as the first non-blank line of the program instead of no indent.
sas.vim	2.1	2016-08-08	7.0	Zhenhuan Hu	Fix an issue when no indent is made at the end of a macro
sas.vim	2.0	2012-05-09	7.0	Zhenhuan Hu	Implemented a brand new algorithm for indenting. Now indenting will be correct with or without close data/proc section by run statement. Added enddata keyword.
sas.vim	1.1	2012-04-30	7.0	Zhenhuan Hu	Optimized the indenting approach. Added keyword QUIT.
sas.vim	1.0	2012-04-26	7.0	Zhenhuan Hu	Initial upload
