function Result = ini2struct(FileName) %========================================================================== % Author: Andriy Nych ( nych.andriy@gmail.com ) % Version: 733341.4155741782200 %========================================================================== % % INI = ini2struct(FileName) % % This function parses INI file FileName and returns it as a structure with % section names and keys as fields. % % Sections from INI file are returned as fields of INI structure. % Each fiels (section of INI file) in turn is structure. % It's fields are variables from the corresponding section of the INI file. % % If INI file contains "oprhan" variables at the beginning, they will be % added as fields to INI structure. % % Lines starting with ';' and '#' are ignored (comments). % % See example below for more information. % % Usually, INI files allow to put spaces and numbers in section names % without restrictions as long as section name is between '[' and ']'. % It makes people crazy to convert them to valid Matlab variables. % For this purpose Matlab provides GENVARNAME function, which does % "Construct a valid MATLAB variable name from a given candidate". % See 'help genvarname' for more information. % % The INI2STRUCT function uses the GENVARNAME to convert strange INI % file string into valid Matlab field names. % % [ test.ini ]~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ % % SectionlessVar1=Oops % SectionlessVar2=I did it again ;o) % [Application] % Title = Cool program % LastDir = c:\Far\Far\Away % NumberOFSections = 2 % [1st section] % param1 = val1 % Param 2 = Val 2 % [Section #2] % param1 = val1 % Param 2 = Val 2 % % ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ % % The function converts this INI file it to the following structure: % % [ MatLab session (R2006b) ]~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ % >> INI = ini2struct('test.ini'); % >> disp(INI) % sectionlessvar1: 'Oops' % sectionlessvar2: 'I did it again ;o)' % application: [1x1 struct] % x1stSection: [1x1 struct] % section0x232: [1x1 struct] % % >> disp(INI.application) % title: 'Cool program' % lastdir: 'c:\Far\Far\Away' % numberofsections: '2' % % >> disp(INI.x1stSection) % param1: 'val1' % param2: 'Val 2' % % >> disp(INI.section0x232) % param1: 'val1' % param2: 'Val 2' % % ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ % % NOTE. % WhatToDoWithMyVeryCoolSectionAndVariableNamesInIniFileMyVeryCoolProgramWrites? % GENVARNAME also does the following: % "Any string that exceeds NAMELENGTHMAX is truncated".
