slint
Checks the Scilab code of given macros against a set of criteria
Calling Sequence
slint(files) slint(files, out) slint(files, conf, resFilename) out = slint(files, conf, print) out = slint(files, print)
Arguments
- files
- matrix of strings: the
.sci
files or the directories to analyze..sce
or other files are ignored. - conf
- a string: the name of the configuration file (by default it's
SCI/modules/slint/etc/slint.xml
). - resFilename
- a string: the path + name of the file of results.
- a boolean: if true the result is printed else the result is a struct.
- out
- a struct (if print is false).
Description
slint has been written to check the "quality" of the Scilab's code according to configurable rules.
Scripts that list Scilab instructions out of any function can be analyzed, provided that their files have the .sci
extension.
![]() | The Scilab code to be analyzed must show no error at compilation time. |
Examples
editor SCI/modules/slint/etc/slint.xml // Main configuration file for criteria editor SCI/modules/slint/tests/unit_tests/files/slint_sample.sci; slint SCI/modules/slint/tests/unit_tests/files/slint_sample.sci;
// File slint_sample.sci: function [a, r]=slint_sample(a, b, a) global param // 1: global keyword sin(abc) // 3: uninitialized abc not in this scope may have side effects // 3wrongname = 3 // invalid variable name => parse error => stops code-checking // 5: Duplicated function arguments: a. (reported after line #1) // 5: Function arguments used as output values: a. (reported after line #1) // 5: A function argument must be preceeded by a single space (a,b, a)(reported after line #1) // 7: function returned value might be unused: r (reported after line #1) a = 1; b = 2; // 9: Two instructions on the same line select a case "a" // 10: empty block case "b" b = 2; else b = 1; end mclose("all"); // 11: The instruction mclose("all") may have any side effects. // 12: McCabe code complexity a = 1d3 // 13: Bad decimal exponent: "e" or "E" instead of "d" or "D" printf("%s %3.2f %d", 3, "abc") // 14: too few data wrt expected ones printf("%s %3.2f %d", 3, "abc", %pi, %t) // 14: too many data wrt expected ones // 15: Maximum line length exceeded at lines #, #, ..
