Should be faster too. (CHORNY) - Add option 'first_level_indent_only' to check only indent where previous line is empty. (CHORNY) 0.07 - ~40% faster since 0.05 0.06 - ~20-25% faster 0.05 - "skip_pod" option to parse() for skipping POD sections. 0.04 - Fix the MANIFEST of the distribution 0.03 - Rudimentary support for emacs local variables. 0.02 - Rudimentary support for vim modelines. 0.01 - Starting initial implementation Makefile.PL000644000000000000 37512637521237 16755 0ustar00unknownunknown000000000000Text-FindIndent-0.11use inc::Module::Install::DSL 1.10; all_from lib/Text/FindIndent.pm test_requires Test::More 0.80 license perl repository https://github.com/tsee/p5-Text-FindIndent use_ptar #Module::Install::PerlTar, to create correct archive on Windows MANIFEST000644000000000000 155312637521260 16147 0ustar00unknownunknown000000000000Text-FindIndent-0.11Changes inc/Module/Install.pm inc/Module/Install/Base.pm inc/Module/Install/Can.pm inc/Module/Install/DSL.pm inc/Module/Install/Fetch.pm inc/Module/Install/Makefile.pm inc/Module/Install/Metadata.pm inc/Module/Install/PerlTar.pm inc/Module/Install/Win32.pm inc/Module/Install/WriteAll.pm lib/Text/FindIndent.pm Makefile.PL MANIFEST This list of files META.yml t/01_compile.t t/02_check_indentation.t t/data/mixed3_1.txt t/data/mixed4_1.txt t/data/mixed4_2.txt t/data/mixed5_1.txt t/data/mixed7_1.txt t/data/mixed7_2.txt t/data/spaces2_1.txt t/data/spaces3_1.txt t/data/spaces3_2.txt t/data/spaces3_3.txt t/data/spaces4_1.txt t/data/spaces4_2.txt t/data/spaces4_3.txt t/data/spaces4_4.txt t/data/spaces5_1.txt t/data/spaces6_1.txt t/data/tabs8_1.txt t/data/tabs8_1_skippod.txt t/data/tabs8_2.txt t/data/tabs8_3.txt t/data/unknown_1.txt META.yml000644000000000000 123012637521265 16264 0ustar00unknownunknown000000000000Text-FindIndent-0.11--- abstract: 'Heuristically determine the indent style' author: - 'Steffen Mueller ' build_requires: ExtUtils::MakeMaker: '6.36' Test::More: '0.80' configure_requires: ExtUtils::MakeMaker: '6.36' distribution_type: module dynamic_config: 0 generated_by: 'Module::Install version 1.16' license: perl meta-spec: url: http://module-build.sourceforge.net/META-spec-v1.4.html version: '1.4' module_name: Text::FindIndent name: Text-FindIndent no_index: directory: - inc - t requires: perl: '5.00503' resources: license: http://dev.perl.org/licenses/ repository: https://github.com/tsee/p5-Text-FindIndent version: '0.11' inc000755000000000000 012637521270 15425 5ustar00unknownunknown000000000000Text-FindIndent-0.11Module000755000000000000 012637521270 16652 5ustar00unknownunknown000000000000Text-FindIndent-0.11/incInstall.pm000644000000000000 3021712637521263 21002 0ustar00unknownunknown000000000000Text-FindIndent-0.11/inc/Module#line 1 package Module::Install; # For any maintainers: # The load order for Module::Install is a bit magic. # It goes something like this... # # IF ( host has Module::Install installed, creating author mode ) { # 1.

Returns a letter followed by a number. If the letter is C, then the text is most likely indented with spaces. The number indicates the number of spaces used for indentation. A C indicates tabs. The number after the C indicates the number characters each level of indentation corresponds to. A C indicates that the indenation style could not be determined. Finally, an C followed by a number means that this many characters are used for each indentation level, but the indentation is an arbitrary number of tabs followed by 0-7 spaces. This can happen if your editor is stupid enough to do smart indentation/whitespace compression. (I.e. replaces all indentations many tabs as possible but leaves the rest as spaces.) The function supports parsing of C I. Those settings override the heuristics. The modeline's options that are recognized are C/C, C/C/C/C, and C/C. Similarly, parsing of C I is somewhat supported. C use explicit settings to override the heuristics but uses style settings only as a fallback. The following options are recognized: C, C, C, and C
