Changelog of BashSupport Pro 2.0

An annotated list of all changes is available in the release announcement.

General

Version 2.0 is a new major version. Make sure to use 1.x instead if you’re on a fallback license without renewal.

  • Added Compatibility with 2021.2.
  • Added Show notification with a link to the annotated list of changes at first start of version 2.0.
  • Added Bundle shfmt binary for Linux PowerPC devices (ppc64le). Due to a lack of hardware and emulators this is mostly untested, so far. ShellCheck for ppc64le isn’t included yet because it’s crashing.
  • Added Settings for project-level global variables, which are ignored by the “Unresolved reference” inspection. Please note, that this is only used when the inspection is enabled. ShellCheck, which is used otherwise, isn’t capable to use the predefined variables.
  • Added Wizard to simplify the initial setup of your IDE for best compatibility with BashSupport Pro. Before several notifications were shown and multiple restarts were necessary.
  • Added Action “BashSupport Pro: Open setup wizard” to launch the setup after the first start.
  • Added Initial implementation to support user-defined shellscript libraries. These libraries allow to work with complex shell projects where a lot of files are automatically sourced before a script is executed. The typical use case is collection of files, which provide many predefined functions. Tested with acme.sh and bashdb sources.
    You can configure the new libraries at Settings > Languages & Frameworks > BashSupport Pro > Shell Script Libraries.
    Improvements to the UI and to the ShellCheck integration will be part of the next beta.
  • Added Code style setting “Use \n UNIX line separator”. By default, new files created from the BashSupport Pro templates have UNIX line separators. An inspection detects mismatched separators in existing scripts. This code style settings allows you turn off this behaviour and use your project’s default line separators instead. This is like IDEA-221381, but works differently.
  • Added Changed the display names of BashSupport Pro’s script language and file type to “Shell Script”. It’s “Shell Script (BashSupport Pro)” if JetBrains Shell is enabled.
  • Added Bundle ShellCheck and shfmt binaries for Linux ARM devices (aarch64). Editing and debugging should work fine now. Please note that JetBrains isn’t officially offering full support of this platform.
  • Updated Bundle universal ShellCheck binary for macOS.
  • Improved “Find Usages” presentation, especially for function calls and variables declared by for or select.
  • Performance Use stub elements for files and functions, this reduces memory usage and also makes things slightly faster.
  • Updated Dropped support for IDEs with major version 2019.3.
  • Updated Built shared library for both Intel and Apple Silicon to prepare for native execution on Apple M1 systems.
  • Updated Update BashSupport Pro’s customized pty4j library to latest upstream code.
  • Updated Moved the shell interpreter settings into a separate configurable at Preferences... > Lanuages & Frameworks > BashSupport Pro > Shell Interpreters.
  • Updated Send os.arch and os.64bit with the optional, anonymous telemetry data.
  • Updated The optional, anonymous telemetry now sends the IP address as a request property. The value is used to retrieve the country of origin. The address value is then removed from the event before the event is stored. The same data is stored for events as before.
  • Fixed Shell files without extensions are now assigned to BashSupport Pro, even if JetBrains Shell is enabled.
  • Fixed Shell functions and variables shown in “Go To Symbol” have a better presentation now.
  • Fixed Fixed exception Project(...) already disposed, which was caused by the shfmt integration.
  • Fixed “Find usages” of a function call now displays “function call” instead of “unknown”
  • Fixed Resolving of variables declared in files also sourced by a sourcing file, e.g. show declarations of a.bash when editing b.bash if main.bash includes a.bash before b.bash.
  • Fixed Find usages of declarations in parameter expansions, e.g. ${varName:=default}.
  • Fixed Read/write access detection for parameter expansions, e.g. ${varName:=default} or ${varName}.
  • Fixed Exception Slow operations are prohibited on EDT when opening the View menu with a script editor opened.
  • Fixed Exception Slow operations are prohibited on EDT. when retrieving documentation for a variable reference.
  • Fixed Exception Incorrect CachedValue use: same CV with different captured context.

Editor

  • Added Quickfix to register an unresolved variable as global variable.
  • Added Show registered global variables in code completion.

  • Improved Changes default color configuration of “ShellCheck code” to “Document comment tag” to make it more visible.
  • Improved Language injection in markdown files with code fence language “bash” is now injecting Bash and not POSIX, i.e. Bash variables and commands are now supported in the injected files. Both JetBrains Markdown and Markdown Navigator are supported.
  • Updated Default to bold font style for shebang lines.
  • Performance Large files are highlighted faster, time-consuming inspections were optimized.
  • Fixed Automatic indentation when entering a linefeed in $() and $(()).
  • Fixed Automatically remove the closing } when entering a backspace in ${}.
  • Fixed Code completion inside ${}.
  • Fixed Highlight source and . commands as keywords. Previously, no highlighting was applied.

  • Added Support variables declared by printf -v VAR.
  • Added declare -p name, declare -F name, and declare -f name are not declaring variables.
  • Added Support files with binary content. Content after exit or exit 0 on the top-level is treated as unparsed, binary content now. This allows to edit scripts, which bundle archives, for example.
  • Added Support time and ! in command pipelines. Rename, etc. now properly works with such commands, e.g. time ! myFunc arg.
  • Added Support SRANDOM supported by Bash 5.1 for code completion, quick documentation, find usages, and more.
  • Added Find usages is now supported for positional parameters $1 to $10.
  • Added Support parsing of the coproc command, e.g coproc COPROC_HANDLES { my_command; }.

  • Improved Parsing of concatenated arguments, as in cmd prefix$arg. This is now one argument, and not two. Syntax-based selections now works as expected.
  • Improved Parsing of incomplete function definitions.
  • Improved Parsing of arithmetic expressions, which span multiple lines.
  • Improved Assignments with an assigned list, e.g. declare myVar=(a b), is now treated as an array variable.

Debugger

  • Added Hide the output of bashdb in the main console window when running on Windows. On Linux and macOS input and output are already handled by a separate bashdb console.
  • Added Show a “Got it” message to tell a user how to show environment variables in the variables panel.

  • Fixed #75: When using the add function comment in google style mode it thinks local variables are global.
  • Fixed Changes to the Google Shell Style Guide settings were not applied to open files.

File Support

  • Added Treat .bashrc, .bash_profile, .bash_logout, and .bash_aliases as Bash files

Run Configurations

  • Added New column “Interpreter arguments” in the shell interpreter settings. This allows a more correct and more flexible configuration of interpreters, especially for WSL on Windows. Now wsl.exe can be used for both Bash and POSIX interpreter types and it’s automatically detected on Windows.
  • Added Environment variables defined by the run configuration are now properly passed on to the WSL environment with the help of the WSLENV variable. Values of WSLENV defined in the run configuration or the system environment are retained.
  • Added Injected shell scripts now show a run icon in the gutter, just like regular scripts do. This allows to quickly run injected scripts as a run configuration with an inlined snippet.
  • Improved Run configuration can now be executed during indexing (aka “Dumb Mode”).
  • Updated The debug action is now hidden for run configurations, which have an inline source snippet
  • Fixed The line marker to execute an injected bash file now unescaped the content if the heredoc allows escape codes.
  • Fixed NullPointerException related to Windows path mapping in the run configuration UI.
  • Fixed Message Unable to locate interpreter when trying to debug a run configuration with configured OS interpreter type.

Inspections and Intentions

  • Added New inspection to highlight unused function arguments. It considers use of $*, $@, shift [n] and implicit usage by for and select.
  • Added New inspection “Function keyword” to highlight usage of the function keyword in POSIX scripts. It replaces ShellCheck’s SC2112 for less aggressive highlighting and also adds a quickfix to remove the keyword.
  • Added New intention to add a function keyword to functions in files, which support it.
  • Added New intention to remove the function keyword where both variants are supported.
  • Added All inspections can now be suppressed for files, functions, and statements using quickfixes. Either ShellCheck directives or a special # bashsupport disable=... comment is used, similarly to ShellCheck.
  • Added New Inspection “Unused global variable”, which is disabled by default for now. If enabled, then the equivalent ShellCheck rule is disabled.
  • Improved Inspection “Unresolved variable” is now treating variables in test commands in the same way as ShellCheck, e.g. [[ $unresolvedVar ]].
  • Improved Inspection “Unresolved variable” is now using the same code as ShellCheck for suppression: SC2154.
  • Added Inspection “Unresolved variable” now has a setting to suppress warnings for UPPERCASE_VARIABLES. It’s disabled by default, just as in ShellCheck.
  • Improved Inspection “Unresolved variable”. Variables in expansions with fallbacks are not highlighted, e.g. ${name:-fallback}. Operators :-, :?, :=, :+ with and without : are supported.
  • Updated Enable inspection “Non-constant path of source directive” by default.
  • Updated Disable ShellCheck’s equivalent test SC1091 if inspection “Non-constant path of source directive” is enabled.
  • Fixed Exception Argument rangeInElement (0,5750) endOffset must not exceed descriptor text range in inspection “Missing source file”.
  • Fixed Don’t show “Convert to quoted string” for words subject to tilde expansion, e.g. ~/$dir/file.txt.
  • Fixed Show quickfix to define a shellcheck source directive for values subject to tilde expansion, e.g. ~/data.
  • Fixed Settings of inspections were not properly saved.
  • Fixed Don’t show Variable could be local in files, which aren’t using bash.
  • Fixed Exception in inspection “Unused function argument” when shift $var was used in a function.

Language Injection

  • Bash is automatically injected into commands: elements of YAML files named codefresh.yml. Alternatively, # type=codefresh in a YAML file with a different name turns on Codefresh injection.
  • Bash is automatically injected into before_install:, script:, and after_success: elements of YAML files named .travis.yml. Alternatively, # type=travis in a YAML file with a different name turns on Travis injection.
  • Fix language injection with embedded sub-expressions
  • Fix an edge-case with the fragment editor of language injection into heredocs
  • Automatically escape $ when it’s entered in a fragment editor of unquoted heredocs
  • Enable ShellCheck for injected Bash scripted edited via “Edit Shell Script Fragment…”
  • New setting to control the automatic injection of Bash into Codefresh and Travis YAML files. Injection is disabled by default on 2020.2 and earlier, because the YAML plugin has bugs.

Spellchecker

  • Added Add “bashsupport” to bashpro dictionary. It’s used by suppression comments, for example.
  • Improved Spellchecking of function and identifier names in camelCase or split by separators such as ::.

Libraries

  • Added New flag “recursive” to library sources. By default script libraries are defined non-recursively.
  • Updated Improve user interface of the library settings.
  • Fixed Exception java.lang.IllegalArgumentException: only VirtualFileWithId are supported when using a shell script library with an injected shell script.
  • Fixed Libraries weren’t working properly on Windows.
  • Fixed “Find references” is now working properly for definitions in library sources, which are referenced by other library sources.

Misc

  • Added Track how many times ShellCheck and shfmt are executed, only the count is sent.
  • Added Open https://www.bashsupport.com/uninstalled in the browser when the plugin is uninstalled.
  • Added Sentry event “uninstalled” is sent when the plugin is uninstalled.
  • Updated Builtin Bash dictionary to accept Coprocess, BASH_VERSINFO, and SRANDOM.
  • Updated Builtin Bash dictionary to accept Coprocess, BASH_VERSINFO, and SRANDOM.
  • Fixed Rename refactoring in scratch files was sometimes setting the wrong name.
  • Updated Minor UI changes to the code style panel.
