Simplify concatenation syntax by disallowing use of , and ; simultaneously #21

ViralBShah · 2011-05-12T09:18:02Z

Why don't we disallow combining comma and semicolon, and comma and space? In other words, the only allowed syntaxes are

[1,2,3,4] # 1d array
[1 2;
3 4] # matrix

Use the first one when you are thinking of arrays or lists, and the second one when you are thinking of matrices.

That seems very reasonable to me.

add compatibility for randexp (Julia PR #9144)

Added IO, show and copy tests.

When calling `jl_error()` or `jl_errorf()`, we must check to see if we are so early in the bringup process that it is dangerous to attempt to construct a backtrace because the data structures used to provide line information are not properly setup. This can be easily triggered by running: ``` julia -C invalid ``` On an `i686-linux-gnu` build, this will hit the "Invalid CPU Name" branch in `jitlayers.cpp`, which calls `jl_errorf()`. This in turn calls `jl_throw()`, which will eventually call `jl_DI_for_fptr` as part of the backtrace printing process, which fails as the object maps are not fully initialized. See the below `gdb` stacktrace for details: ``` $ gdb -batch -ex 'r' -ex 'bt' --args ./julia -C invalid ... fatal: error thrown and no exception handler available.

(cherry picked from commit 21ab24e)

When calling `jl_error()` or `jl_errorf()`, we must check to see if we are so early in the bringup process that it is dangerous to attempt to construct a backtrace because the data structures used to provide line information are not properly setup. This can be easily triggered by running: ``` julia -C invalid ``` On an `i686-linux-gnu` build, this will hit the "Invalid CPU Name" branch in `jitlayers.cpp`, which calls `jl_errorf()`. This in turn calls `jl_throw()`, which will eventually call `jl_DI_for_fptr` as part of the backtrace printing process, which fails as the object maps are not fully initialized. See the below `gdb` stacktrace for details: ``` $ gdb -batch -ex 'r' -ex 'bt' --args ./julia -C invalid ... fatal: error thrown and no exception handler available.
