Shell Environment Variables[Bearbeiten]
A number of shell environment variables are used (if present) by expecco and/or the underlying Smalltalk runtime system. Their existance is not a prerequisite to run expecco: default values will be used, if those variables are not present.
Temporary Files Folder[Bearbeiten]
Expecco (and Smalltalk) may create temporary files, which may outlive your session, in case of an abnormal termination (or in case a suite fails to cleanup temporary files correctly).
By default, temporary files are created inside a per-session temporary folder.
This per-session temporary folder is named "stx_tmp_xxxx" (where xxxx is a session/process-ID) and is created in the tempdir folder.
The tempdir folder is specified by any of: STX_TMPDIR, TMP_DIR, TEMP_DIR, TMPDIR or TEMPDIR,
whichever is found in the shell environment.
If none of the above is found in the shell environment, "/tmp" is used as tempdir.
All per-session temporary files are created in this one temporary folder, to make it easier to cleanup leftover session files.
Actually, if no expecco/Smalltalk is running, all temporary file folders named "stx_tmp_xxx" can be removed without danger (although temp-file cleanup is typically done automatically by the operating system in regular intervals)
The name of the temporary folder can be retrieved by evaluating and printing:
Filename tempDirectory
(doing a "printIt" in a Smalltalk workspace), or via a corresponding action block in the standardlibrary.
Script Interpreters for External Language Scripts[Bearbeiten]
If no script interpreter was defined in the settings dialog, fallbacks can be provided by the following shell variables:
- CMD_SHELL (batch scripts; defaults to "
cmd") - SHELL (shell commands and shell scripts; defaults to "
bash" or "sh", whichever is found) - POWERSHELL (powershell scripts; defaults to "
powershell" or "pwsh", whichever is found) - RUBY_SHELL (ruby scripts; defaults to "
ruby") - PYTHON_SHELL (python scripts; defaults to "
python") - PERL_SHELL (perl scripts; defaults to "
perl") - TCL_SHELL (tcl scripts; defaults to "
tclsh") - NODEJS_SHELL (node.js scripts; defaults to "
node") - GO_SHELL (go scripts; defaults to "
go") - GNUPLOT_SHELL (gnuplot scripts; defaults to "
gnuplot") - RSCRIPT_SHELL ('R' scripts; defaults to "
R.exe" on Windows, "r" on OSX, "R" on Unix/Linux)
