In POSIX Base Definitions Section 8.1 Environment Variable Definition,
it is explained that the `COLUMNS` and `LINES` environment variables,
if present, take precedence over any other implementation-defined method
to determine the terminal size. This is useful, for example, to capture
output programmatically in simulations for various terminal sizes.
* std/bitops: Add explicit type masking for the JS target
Typecasts on the JavaScript backend do not function the same way as they
do on C and C++ backends, so for bitwise operations we may need to mask them
back down into their allowed range when they get shifted outside it.
Since they do work as expected on the other backends, a default bitmask
of all 1's is casted down into the target type as an easily optimizable
"& 0xFF" operation for these backends.
* Fixup: this should still be a func
* Run test case on js target
* Adapt testcase to contributor guide and best practices
* Simplify constrain logic and turn into actual no-op for the C side
This fixes a regression introduced in #20990 . When a group referencing
is used and one of the overloaded symbols is in `include`d file, then
`nim doc` crashes. The fix is in distinguishing (the index of) module
and file where the symbol is defined, and using only module as the
key in hash table for group referencing.
* document general use of `_`, error message, fixes
fixes#20687, fixes#21435
Documentation and changelog updated to clarify new universal behavior
of `_`. Also new error message for attempting to use `_`, new tests,
and fixes with overloadable symbols and
implicit generics.
* add test for #21435
* tuple unpacking for vars as just sugar, allowing nesting
* set temp symbol AST
* hopeful fix some issues, add test for #19364
* always use temp for consts
* document, fix small issue
* fix manual indentation
* actually fix manual
* use helper proc
* don't resem temp tuple assignment
`len` could contain side effects and may result in different values when
substituted twice in the template expansion. Instead, capture the result
of substituting `len` once.
closes: #21538
* Add a test case
There are way more test cases (See all branches of analyseIfAddressTaken but this covers at least a second branch
* Port analyseIfAddressTaken from semexprs to sigmatch
This was done since we cannot import sem or semexprs (circular import) but we need the rest of the logic. In needs to be done here since the converter isn't semmed afterwards and so we can't just leave the process til later use the version from semexprs
* Less hacky solution which has the checking be done in analyseIfAddressTakenInCall
This was done instead of the recommendation on removing it since sfAddrTaken is used in places other than the backend
* Remove weird whitespace
* Still check nkHiddenAddr if we are checking a converter
* Fix custom objects, fix handling of nil variables
* Rename because lldb complains about dashes in filename
* Add example of how to use custom type formatting from Nim
* Add synthetic objects with dynamic fields and add an example
* fix#18977 disallow change branch of an object variant in ORC
* check errors for goto exception
* fixes conditions
* fixes tests
* add a test case for #18977
