News

Version 1.1.4 (March 25, 2019) HOTFIX for CRAN

  • Fixes the issue #41: Error when the tryCatchLog package was not attached first using library or depends (https://github.com/aryoda/tryCatchLog/issues/41)
  • Added simple unit test for issue #41
  • Restructured some unit tests since testthat with devtools has a known limitation required by some tests: "Can't detach package in tests" (https://github.com/r-lib/devtools/issues/1797)
  • Removed german umlaut from the DESCRIPTION file to keep it ASCII-only (required due to a new note produced by the winbuilder service)

Version 1.1.3 (March 21, 2019) HOTFIX (github only)

  • Release candidate to fix issue #41: Error when the tryCatchLog package was not attached first using library or depends

Version 1.1.2 (March 13, 2019) - published at CRAN (March 20, 2019)

  • Fixed issue #39: Dump files may be overwritten when multiple errors occur at the same second in the same or parallel processes. See: https://github.com/aryoda/tryCatchLog/issues/39
  • Creates a (hopefully) unique dump file name incl. milliseconds and the process id in the file name, eg.: dump_2019-03-13_at_15-39-33.086_PID_15270.rda

Version 1.1.1 (Dec. 24, 2018)

  • Added parameter and options to write dump files into a specific folder: See new write.error.dump.folder parameter and new tryCatchLog.write.error.dump.folder option. Contributed by Charles Epaillard. Closes https://github.com/aryoda/tryCatchLog/issues/37

    API breaking change: tryLog has a changed API due to the newly inserted parameter write.error.dump.folder at position 3. Adjust your source code if you call tryLog and pass arguments by position using more than 2 arguments).

  • Added new function get.pretty.tryCatchLog.options for a convenient way of printing and logging the current values of all options supported by the tryCatchLog package

Version 1.1.0 (June 02, 2018)

  • Implemented feature request #10 (allow injection of own logging functions): Added function set.logging.functions(). For details see: https://github.com/aryoda/tryCatchLog/issues/10
  • Removed hard dependency from package futile.logger (in Imports section of DESCRIPTION file) by implementing a package internal basic logging function log2console used as default if the package futile.logger is not installed
  • Dependency of package futile.logger is now only Suggests in the DESCRIPTION file, no longer Imports

Version 1.0.3 (May 21, 2018)

  • Fixes issue #29 (bug): limitedLabelsCompact does ignore maxwidth argument (logged call stack is too long)
  • Refactored R code to improve unit tests (via mocking)
  • Fixed typo in function documentation
  • Added AppVeyor CI to github repository for automatic builds on Windows (besides the existing ones on Linux)

Version 1.0.1 (May 5, 2018)

  • Vignette is using now rmarkdown::html_vignette as output to minimize the HTML file size
  • Refactored vignette doc into smaller reusable parts (for slides + "booklet").
  • Removed package revealjs from "recommended" section in DESCRIPTION file

Version 1.0.0 (April 26, 2018)

  • travis CI builds now against R3.2, current release, old release and devel (dev version)

Version 0.9.12 (Dec. 17, 2017)

  • Fixed R CMD check warning (Undocumented code objects: ‘build.log.output’)
  • Added github repository to travis CI (automatic building and testing)
  • Added github repository codecov.io code coverage report (with badge image in the readme file)
  • Improved code coverage (more unit tests)

Version 0.9.11 (Dec. 12, 2017)

  • Fixed bug (issue #21): Silent.warnings (and messages) in tryLog and tryCatchLog not working for bubbled-up warnings

Version 0.9.10 (Dec. 10, 2017)

  • SEMANTICAL CHANGE: Renamed tryCatchLog argument "dump.errors.to.file" to "write.error.dump.file" to be more precise. THIS BREAKS THE OLD INTERFACE (FUNCTION SIGNATURE!)

  • Fixed bug #18 (duplicated errors, warnings and messages in stacked tryCatchLog calls
  • Closes #20 (support for OS-specific newline characters in build.log.output)
  • Improved documentation of last.tryCatch.result
  • build.log.output: Added arguments for incl.timestamp + incl.severity as option to suppress redundant output if a logging framework is used
  • Open issue: R CMD check results in one warning (false positive: missing documentation entries for build.log.output)

Version 0.9.8 (Nov. 23, 2017)

  • Exported function build.log.output to create a single string suited as logging output from last.tryCatchLog.result
  • build.log.output extended to support not only one but many log entry rows at once
  • R CMD check results: 0 errors | 1 warnings | 0 notes: Undocumented code objects: ‘build.log.output’ -> is a false positive (reason still unclear)

Version 0.9.7 (Nov. 22, 2017)

  • SEMANTICAL CHANGE: last.tryCatch.result returns now a data.frame with separated logging items in columns
  • internal refactorings with more unit tests
  • R CMD check results: 0 errors | 0 warnings | 0 notes

Version 0.9.6 (Nov. 18, 2017)

  • SEMANTICAL CHANGES: Changed error handler semantics in tryCatchLog to be as close to tryCatch as possible
  • CHANGE OF SIGNATURE: Default value for error handler in tryCatchLog removed
  • Debugging error handler problem if used in RStudio (tryCatchLog(log("a"))
  • Renamed last.tryCatchLog.log to last.tryCatchLog.result (clearer und avoid R CMD CHECK problem)

Version 0.9.5 (Nov. 18, 2017)

  • Added: Function last.tryCatchLog.log to retrieve the log output of the call of tryLog or tryCatchLog
  • Fixed bug #17: tryCatchLog throws: Error in value[3L] : unused argument (cond)
  • NULL as value for error argument throws an explicit error (instead of an implicit deep down in R)

  • License: Added the copyright header to each R file to clarify the legal side
