2.0 -- UNRELEASED

This release moves the library to clj-commons, and changes the root namespace from io.aviso to clj-commons. It strips down the library to its essentials, removing the columns, component, and logging namespaces entirely.

• Stripped out a lot of redundant documentation
• Reworked the ansi namespace to primarily expose the compose function and not dozens of constants and functions
• ansi determines whether to enable or disable ANSI codes at execution time
• ansi now honors the NO_COLOR environment variable
• Stripped out code for accessing the clipboard from the repl namespace
• Some refactoring inside exceptions namespace, including changes to the *fonts* var
• Removed the logging namespace and dependency on org.clojure/tools.logging
• Removed the component namespace, but the example is still present in the documentation
• Ensure compatible with Clojure 1.10 and above (now tested in GitHub action)
• The "use -XX:-OmitStackTraceInFastThrow" warning is now formatted, and is output only once
• write-exception was renamed to print-exception
• write-binary and write-binary-delta renamed to print-binary and print-binary-delta
• compose can now pad a span of text with spaces (on the left or right) to a desired width
• Binary output now includes color coding

1.4.4 -- 20 Jun 2023

• Fixed: Incorrectly named font terms with compose
• Fixed: Incorrect ANSI codes for bright and bright background colors

Closed Issues

1.4.3 -- 24 May 2023

The compose function would collapse blank strings to empty strings.

Closed Issues

1.4.1, 1.4.2 -- 5 May 2023

io.aviso.ansi: Add support for faint, underlined, and not-underlined text, and improvements to docstrings.

Closed issues

1.4 -- 27 Mar 2023

A new function, io.aviso.ansi/compose uses a Hiccup-inspired syntax to make composing text with ANSI fonts (foreground and background colors, inverse, bold, and italic) easy and concise.

The override to enable or disable ANSI text has been amended: the first check is for a JVM system property, io.aviso.ansi.enable, then if that is not set, the ENABLE_ANSI_COLORS environment variable.

Closed issues

1.3 -- 20 Oct 2022

The default stack frame filter now terminates at any speclj.* namespace.

The io.aviso.ansi namespace now determines whether output is connected to a terminal, and disables fonts and colors if so; this can be overridden with the ENABLE_ANSI_COLORS environment variable.

Added a -main function to io.aviso.repl; this installs pretty exceptions before delegating to clojure.main/main. Thus, clojure -m io.aviso.repl -m org.example.myapp will ultimately pass any remaining command line arguments to org.example.myapp/-main.

The pretty replacement for clojure.repl/pst now writes to *err*, not *out*.

1.2 -- 30 Sep 2022

Output from write-exception is now buffered; this should reduce the interleaving of exception output when multiple threads are writing exceptions simultaneously.

Closed Issues

1.1.1 -- 15 Dec 2021

Prevent warnings when using with Clojure 1.11.

Closed Issues

1.1 -- 16 May 2021

Restore compatibility with Clojure 1.7.0.

1.0 - 16 May 2021

BinaryData protocol extended onto java.nio.ByteBuffer.

Closed Issues

0.1.37 - 30 Jan 2019

Incompatible Changes:

• Removed the io.aviso.writer namespace and changed many functions to simply write to *out* rather than take a writer parameter.

• It is now necessary to setup explicit :middleware in your project.clj, as Leiningen is phasing out implicit middleware. See the manual for more details.

Closed Issues

0.1.36 - 22 Dec 2018

Support Clojure 1.10.

Add support for highlighting application frames using io.aviso.exception/*app-frame-names*.

Closed Issues

0.1.35 - 28 Sep 2018

When printing sorted maps, the keys are presented in map order (not sorted).

The new namespace, io.aviso.component, can be used to produce concise output for systems and components that are pretty printed as part of exception output.

Closed Issues

0.1.34 - 28 Jun 2017

Added possibility to disable default ANSI fonts by setting an environment variable DISABLE_DEFAULT_PRETTY_FONTS to any value.

Closed Issues

0.1.33 - 28 Nov 2016

Closed Issues

0.1.32 - 18 Nov 2016

New functions in io.aviso.repl for copying text from the clipboard, and pretty printing it as EDN or as a formatted exception.

0.1.31 - 15 Nov 2016

Switch to using macros instead of eval to play nicer with AOT

Support all arities of clojure.repl/pst

Closed Issues

0.1.30 - 16 Aug 2016

Fix bad ns declaration and reflection warnings

0.1.29 - 19 Jul 2016

Fix an issue where the code injected by the plugin could get damaged by other plugins, resulting in a ClassNotFoundException.

0.1.28 - 15 Jul 2016

A warning is now produced when using pretty as a plugin, but it is not a project dependency.

Closed Issues

0.1.27 - 1 Jul 2016

Qualified keys in exception maps are now printed properly.

0.1.26 - 15 Apr 2016

To get around Clojure 1.8 deep linking, io.aviso.repl/install-pretty-exceptions now reloads clojure.test after overriding other functions (such as clojure.stacktrace/print-stack-trace).

Closed Issues

0.1.25 - 5 Apr 2016

The writer used in write-exception is now locked and flush on newline is disabled; this helps ensure that multiple threads do not write their output interspersed in an unreadable way.

0.1.24 - 26 Feb 2016

Internal change to how exception properties are pretty-printed.

0.1.23 - 11 Feb 2016

parse-exception can now handle method names containing < and > (used for instance and class constructor methods), as well as other cases from real-life stack traces.

Stack traces were omitted when the root exception was via ex-info; this has been corrected.

Closed issues

0.1.22 - 5 Feb 2016

Fixed a bug where parse-exception would fail if the source was "Unknown Source" instead of a file name and line number.

Closed issues

0.1.21 - 8 Jan 2016

Improved docstrings for ANSI font constants and functions.

Added support for invokePrim() stack frames. These are hidden as with Clojure 1.8 invokeStatic() frames.

Stack frames that represent REPL input now appear as REPL Input in the file column, rather than something like form-init9201216130440431126.clj.

Source files with extension .cljc (introduced in Clojure 1.7) are now recognized as Clojure code.

It is now possible to parse a block of exception text (say, copied from an output log) so that it may be formatted. Because of the wide range in which different JDKs may output exceptions, this is considered experimental.

Incompatible change: write-binary now expects an optional map (not a varargs of keys and values) for options such as :ascii and :line-bytes.

0.1.20 - 4 Dec 2015

Pretty will identify repeating stack frames (for example, from an infinite loop) and only print the stack frame once, but append the number of times it repeats.

Made an adjustment for Clojure 1.8's new direct linking feature.

Improved the way Pretty acts as a Leiningen plugin. Pretty exceptions reports are now produced for both REPL sessions and test executions.

The io.aviso.nrepl namespace has been removed.

Closed issues

0.1.19 - 27 Aug 2015

Print a blank line before the exception output, when reporting a clojure.test exception. Previously, the first line was was on the same line as the "actual:" label, which interfered with columnar output.

The built in stack frame filtering rules are now better documented, and speclj.* is now included as :terminate.

You may now add pretty to your Leiningen :plugins list; it will automatically add the Pretty nREPL middleware.

Closed issues

0.1.18 - 5 May 2015

io.aviso.repl/install-pretty-logging now installs a default Thread uncaughtExceptionHandler.

There's a new arity of io.aviso.columns/write-rows that streamlines the whole process (it can calculate column widths automatically).

The Clojure ExceptionInfo exception is now treated specially.

Closed issues

0.1.17 - 18 Feb 2015

Changed io.aviso.logging to always use the current value of *default-logging-filter* rather than capturing its value when install-pretty-logging is invoked.

Sometimes, the file name of a stack trace element is a complete path (this occurs with some testing frameworks); in that case, Pretty will now strip off the prefix from the path, when it matches the current directory path. This keeps the file name column as narrow as possible.

0.1.16 - 4 Feb 2015

io.aviso.exception/*default-frame-filter* has been added, and acts as the default frame filter for write-exception (previously there was no default).

Closed issues

0.1.15 - 2 Feb 2015

Starting in this release, the exception report layout has changed significantly; however, the old behavior is still available via the io.aviso.exceptions/*traditional* dynamic var.

A new namespace, io.aviso.logging, includes code to setup clojure.tools.logging to make use of pretty exception output.

Closed issues

0.1.14 - 9 Jan 2015

Closed issues

0.1.13 - 14 Nov 2014

It is now possible to control how particular types are formatted when printing the properties of an exception. This can be very useful when using (for example) Stuart Sierra's component library.

0.1.12 - 27 May 2014

The default stack-frame filter now excludes frames from the sun.reflect package (and sub-packages).

For exceptions added via io.aviso.repl/install-pretty-exceptions, the filtering omits frames from the clojure.lang package, and terminates output when the frames for the REPL are reached.

0.1.11 - 14 May 2014

It is now possible to specify a filter for stack frames in the exception output. Frames can be hidden (not displayed at all), or omitted (replaced with '...').

This can remove significant clutter from the exception output, making it that much easier to identify the true cause of the exception.
