From 3248801a925449644071671dcd85e370303071b4 Mon Sep 17 00:00:00 2001 From: Nick Wellnhofer Date: Fri, 23 Jan 2015 17:04:14 +0100 Subject: Improve version information Add version number and string as macros and symbols. Version numbers can be easily compared, for example in the C preprocessor: #include #if CMARK_VERSION < 0x020200 #error Requires libcmark 2.2.0 or higher #endif Storing the version in a global variable allows to check the library version at runtime. For example: if (CMARK_VERSION != cmark_version) { warn("Compiled against libcmark %s, but using %s", CMARK_VERSION_STRING, cmark_version_string); } The version should be updated whenever the public API is changed. --- src/cmark.h | 33 +++++++++++++++++++++++++++++---- 1 file changed, 29 insertions(+), 4 deletions(-) (limited to 'src/cmark.h') diff --git a/src/cmark.h b/src/cmark.h index 8177fa8..faa5150 100644 --- a/src/cmark.h +++ b/src/cmark.h @@ -18,10 +18,6 @@ extern "C" { * ## Simple Interface */ -/** Current version of library. - */ -#define CMARK_VERSION "0.1" - /** Convert 'text' (assumed to be a UTF-8 encoded string with length * 'len' from CommonMark Markdown to HTML, returning a null-terminated, * UTF-8-encoded string. @@ -499,6 +495,35 @@ char *cmark_render_man(cmark_node *root, long options); */ #define CMARK_OPT_NORMALIZE 4 +/** + * ## Version information + */ + +/** Macro containing the library version as integer for compile time + * checks. + * + * * Bits 16-23 contain the major version. + * * Bits 8-15 contain the minor version. + * * Bits 0-7 contain the patchlevel. + * + * In hexadecimal format, the number 0x010203 represents version 1.2.3. + */ +#define CMARK_VERSION 0x000100 + +/** Macro containing the library version string for compile time checks. + */ +#define CMARK_VERSION_STRING "0.1.0" + +/** The library version as integer for runtime checks. + */ +CMARK_EXPORT +extern const int cmark_version; + +/** The library version string for runtime checks. + */ +CMARK_EXPORT +extern const char cmark_version_string[]; + /** # AUTHORS * * John MacFarlane, Vicent Marti, Kārlis Gaņģis, Nick Wellnhofer. -- cgit v1.2.3 From 3ed64d7568437e81a0746554af273faeaf2037b4 Mon Sep 17 00:00:00 2001 From: Nick Wellnhofer Date: Fri, 23 Jan 2015 21:26:49 +0100 Subject: Let cmake update version Add a new template cmark_version.h.in to generate cmark_version.h containing version information. --- CMakeLists.txt | 4 ++-- man/man3/cmark.3 | 33 +++++---------------------------- src/CMakeLists.txt | 8 +++++++- src/cmark.h | 18 ++++++------------ src/cmark_version.h.in | 7 +++++++ 5 files changed, 27 insertions(+), 43 deletions(-) create mode 100644 src/cmark_version.h.in (limited to 'src/cmark.h') diff --git a/CMakeLists.txt b/CMakeLists.txt index 6bf4cd6..a6caee6 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -8,8 +8,8 @@ endif() set(PROJECT_NAME "cmark") set(PROJECT_VERSION_MAJOR 0) -set(PROJECT_VERSION_MINOR 0) -set(PROJECT_VERSION_PATCH 1) +set(PROJECT_VERSION_MINOR 1) +set(PROJECT_VERSION_PATCH 0) set(PROJECT_VERSION ${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}.${PROJECT_VERSION_PATCH} ) add_subdirectory(src) diff --git a/man/man3/cmark.3 b/man/man3/cmark.3 index f03a3ae..4b24391 100644 --- a/man/man3/cmark.3 +++ b/man/man3/cmark.3 @@ -527,14 +527,14 @@ Version information .nf \fC .RS 0n -#define CMARK_VERSION 0x000100 +extern const int cmark_version; .RE \f[] .fi .PP -Macro containing the library version as integer for compile time -checks. +The library version as integer for runtime checks.
