* Back to old encoding of versions in binary filesRoberto Ierusalimschy2020-05-061-1/+1
| | | | | | (Undoing part of commit f53eabeed8.) It is better to keep this encoding stable, so that all Lua versions can read at least the version of a binary file.
* Fixed warning about casts between function pointersRoberto Ierusalimschy2020-04-291-1/+8
| | | | | | gcc now warns (with -Wextra) about casts between pointers to different function types. The type 'void(*)(void)' works as a 'void*' for function pointers, cleaning the warning.
* Several details about 5.4.0 rc1Roberto Ierusalimschy2020-04-231-2/+0
| | | | | Corrected several small details: added 'const', adjusts in tabs x spaces, removed unused #includes and #defines, misspellings, etc.
* Change in the prefix of messages from searchersRoberto Ierusalimschy2019-10-241-5/+9
| | | | | | The initial "\n\t" to properly indent a searcher message is being added by 'findloader' when building the error message, instead of being included in the original message by each searcher itself.
* Fixed a warning and other minor issuesRoberto Ierusalimschy2019-10-041-1/+1
| | | | Fixed some minor issues from the feedback for 5.4-beta rc1.
* Added macro 'luaL_pushfail'Roberto Ierusalimschy2019-08-161-4/+4
| | | | | | | | The macro 'luaL_pushfail' documents all places in the standard libraries that return nil to signal some kind of failure. It is defined as 'lua_pushnil'. The manual also got a notation (@fail) to document those returns. The tests were changed to be agnostic regarding whether 'fail' is 'nil' or 'false'.
* Avoid using addresses of static variables as unique keysRoberto Ierusalimschy2019-07-191-6/+5
| | | | | | The addresses of static variables may be different for different instances of Lua, making these instances incompatible if they use these addresses as unique keys in the registry (or other tables).

* Avoid the creation of too many strings in 'package'Roberto Ierusalimschy2019-05-031-31/+58
| | | | | | | | | Both when setting a path and searching for a file ('searchpath'), this commit reduces the number of intermediate strings created in Lua. (For setting a path the change is not relevant, because this is done only twice when loading the module. Anyway, it is a nice example of how to use auxlib buffers to manipulate strings in the C API.)
* 'require' returns where module was foundRoberto Ierusalimschy2019-04-171-6/+17
| | | | | The function 'require' returns the *loader data* as a second result. For file searchers, this data is the path where they found the module.
* Removed extra information from RCS keyword stringsRoberto Ierusalimschy2018-08-231-1/+1
| | | | | Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.
* 'searchpath' creates less temporary stringsRoberto Ierusalimschy2018-07-091-18/+34
| | | | | | | When creating error messages, package loaders may create dozens of temporary strings (one or more for each tried template). This change reduces the number of these strings, and avoid creating some of them if the search is successful.
