# Release Notes

# 1.9.1

## New:
- Implemented support for [envFile](https:/vadimcn/codelldb/issues/866).
- Added `breakpointMode` setting: when this is set to `file`, breakpoints will be resolved using file name only, which
is similar to how `breakpoint set -f <filename> -l <line>` command works in CLI LLDB. This relieves the need
of setting up `sourceMap`; however, this is at the expense of potentially hitting unexpectd breakpoints
if there is more than one source file of the same name in the project.
- `targetCreateCommands` and `processCreateCommands` are now allowed in for `launch` and `attach` requests. When
specified, these command sequences over-ride the default logic for target and process creation.

## Fixed
- #761: Error: there is no registered task type 'codelldb.cargo'
- #776: Error: there is no registered task type 'codelldb.cargo'
- #891: Incorrect matcher
- #904: Cannot see VecDeque values in "Variables" panel after insert
- #911: Vec in sidebar shows wrong (old) value
- #920: Rust: local variables not updated during debugging
- #915: Pick(My)Process not working

# 1.9.0

# Settings
## Default Launch Configuration Settings
These settings specify the default values for launch configuration setting of the same name.
When a setting is specified in both locations, the values will be merged depending on their type:
## Workspace Settings
The "Workspace Settings" term used in the document refers to the combined view of [VSCode User and Workspace settings](https://code.visualstudio.com/docs/getstarted/settings), merged according to the
[settings precedence](https://code.visualstudio.com/docs/getstarted/settings#_settings-precedence) hierarchy.
## Launch Configurations Settings
VSCode [launch configuration](https://code.visualstudio.com/docs/editor/debugging#_launch-configurations)
settings are distinct from workspace settings and are not subject to the usual settings merging described above.
However, since common defaults for all launch configurations in a project are often desired, the CodeLLDB extension
provides this feature via [`lldb.launch.*`](#default-launch-configuration-settings) setting group, which serve as defaults
for the corresponding launch configuration settings. When a setting is specified in both locations, the values will
be merged according to on their type:
- For lists, the resulting value will be a concatenation of both sources.
- For dictionaties, the resulting value will be a combination of key-value pairs from both sources. For equal keys,
the launch configuration value is used.
- For numbers and strings, the launch configuration value is used.
the launch configuration value takes precedence.
- For numbers and strings, the launch configuration value takes precedence.
### Variable Substitution in Launch Configurations
Before being sent to the debug adapter, launch configuration settings undergo expansion of
[variable references](https://code.visualstudio.com/docs/editor/variables-reference).
In addition to the standard expansions performed by VSCode, CodeLLDB also expands references to
[`${dbgconfig:<name>}`](#parameterized-launch-configurations) as well as [`${cargo:program}`](#cargo-support).
## LLDB Settings
The LLDB debugger engine also has a number of internal settings, which affect its behavior. These
may be changed using `settings set <key> <value>` command, which may be put into any of the
`*Commands` launch configuration sequences (usually `initCommands`).
The full list of LLDB settings may be obtained by executing `settings list` command during a debug session (or in LLDB command prompt).
