     1  # v2.5
     2  
     3  This release introduces a number of new builtins, fixes some regression bugs and supercharges the `select` optional builtin (which I plan to include into the core builtins for non-Windows users in the next release).
     4  
     5  ### Features:
     6  
     7  * `alter` now supports `--sum` where structures are merged and numeric values are added together
     8  
     9  * New builtin `count`. This has deprecated `len` however `len` will stick around as an alias for backwards compatibility
    10  
    11  * New operators added to `let`: `+=`, `-=`, `/=`, `*=`
    12  
    13  * New builtin `addheading` for adding headings to lists
    14  
    15  * Compiled profile will now always execute even if Murex flags set to ignore the modules/user profile. This is so that aliases like `len` get set and thus Murex can still move forward with changes to builtins but without breaking backwards compatibility
    16  
    17  * `autocomplete` now passes `ISMETHOD` variable to dynamic completions so those dynamic completions are aware if a command requesting auto-completion suggestions is being invoked as a method (mid-pipeline) or function (start of a pipeline)
    18  
    19  * Index, `[`, now supports inlining element, `[[`, lookups. eg `[ a b [/map/c] ]`
    20  
    21  * Dynamic auto-completions that include `@IncFiles` or `@IncDirs` will now automatically append files and/or directories to their auto-completion suggestions
    22  
    23  * New `autocomplete` directives: `IncExeAll` (like `IncExePath` but includes builtins, functions, aliases), `IncManPage` (include results from the `man` page parser -- usually suppressed when `autocomplete` config is set)
    24  
    25  * Disabled 'Loading default profile' message -- this was always pretty redundant but now that the compiled profile is being loaded all the time (eg `murex -c 'command'` or when called in a shebang), it's also now ugly too
    26  
    27  * `select` now supports passing a file in the **FROM** syntax. eg `select * FROM ./example.csv`. The caveat here is this breaks currently auto-complete on column names
    28  
    29  * `select` now supports multiple tables using either named pipes (eg `select * FROM <table1>, <table2>`) or variables (eg `select * FROM \$table1, \$table2`) passed in the **FROM** syntax. Variables should be escaped and you cannot mix and match between named pipes, file names nor variables. You can use any number of tables from 1 to 2^63-1 (64bit systems) or 1 to 2^31-1 (32bit systems). Which should be more than enough ;)
    30  
    31  * `config` option for `select` to define default output data type where multiple tables are imported
    32  
    33  * Lots of new and updated documentation!
    34  
    35  ### Non-user facing changes (internal changes to the Murex code base):
    36  
    37  * `open` functions can now be called by other functions to take advantage of auto-typing and auto gunzip etc.
    38  
    39  * `tmp.Close()` should return `err`. This isn't a bug but it might catch future bugs
    40  
    41  * `LazyLogging` created to speed up writing tests against data structures
    42  
    43  * `utils/List` package created to handle list / array / map functions. Also makes testing more complex routines easier
    44  
    45  ### Bug fixes:
    46  
    47  * Regression bug fixed where `prepend` was invoking `append`
    48  
    49  * `streams.ReadCloser` not setting context
    50  
    51  * `parameters.StringArray()` should copy values instead of a pointer to ensure the underlying parameters are immutable
