Variables controlling indentation style:
 simula-tab-always-indent
    Non-nil means TAB in SIMULA mode should always reindent the current line,
    regardless of where in the line point is when the TAB command is used.
 simula-indent-level
    Indentation of SIMULA statements with respect to containing block.
 simula-substatement-offset
    Extra indentation after DO, THEN, ELSE, WHEN and OTHERWISE.
 simula-continued-statement-offset 3
    Extra indentation for lines not starting a statement or substatement,
    e.g. a nested FOR-loop.  If value is a list, each line in a multiple-
    line continued statement will have the car of the list extra indentation
    with respect to the previous line of the statement.
 simula-label-offset -4711
    Offset of SIMULA label lines relative to usual indentation.
 simula-if-indent '(0 . 0)
    Extra indentation of THEN and ELSE with respect to the starting IF.
    Value is a cons cell, the car is extra THEN indentation and the cdr
    extra ELSE indentation.  IF after ELSE is indented as the starting IF.
 simula-inspect-indent '(0 . 0)
    Extra indentation of WHEN and OTHERWISE with respect to the
    corresponding INSPECT.  Value is a cons cell, the car is
    extra WHEN indentation and the cdr extra OTHERWISE indentation.
 simula-electric-indent nil
    If this variable is non-nil, `simula-indent-line'
    will check the previous line to see if it has to be reindented.
 simula-abbrev-keyword 'upcase
    Determine how SIMULA keywords will be expanded.  Value is one of
    the symbols `upcase', `downcase', `capitalize', (as in) `abbrev-table',
    or nil if they should not be changed.
 simula-abbrev-stdproc 'abbrev-table
    Determine how standard SIMULA procedure and class names will be
    expanded. Value is one of the symbols `upcase', `downcase', `capitalize',
    (as in) `abbrev-table', or nil if they should not be changed.

Turning on SIMULA mode calls the value of the variable simula-mode-hook
with no arguments, if that value is non-nil

Warning: simula-mode-hook should not read in an abbrev file without calling
the function simula-install-standard-abbrevs afterwards, preferably not
at all."

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
