0.7.0

Changes

• Default space mode is now light.
• Rework a lot of naming:
  • \def became \macro.
  • The convention for local variant of \command is \local_command, with an alias \lcommand.
  • All old names (\def, \defl, \def_local, \setl, \set_local, \default_local, \alias_local, and \aliasl) are deprecated, but work for now.
• Deprecate \redef and \redef_forced. Writing over existing macros will now just print a warning.
• The first parameter of \if, \elseif, \for, and \while must now be an eval block.
• You can now declare a Plume block inside a Lua block. (only works inside plume files for now, not in external Lua files)
• Change eval escape to $ from #. Code using # still works for now.
• Change comment syntax to \-- from //. Code using // still works for now.
• New option join for \for, which will insert a character between all iterations.
• ${x} will now render all x elements if x is a table.
• New flag no_table_join and new option join for macro $.

Explanations for the syntaxs changes:

Originally, # was chosen to adhere to the LaTeX macro syntax, \newcommand \double[1] {#1 #1}. However, it doesn't necessarily align with the broader use that Plume makes of it. Moreover, # is used by Lua, which makes some expressions unclear (e.g., #{#t} to print the size of a table) and prevents it from being used to declare plume blocks inside lua blocks. Finally, $ is much more associated with the evaluate function than #.

As for comments, the idea was to reduce the number of special characters to two in order to avoid the need for escaping as much as possible. (For example, // is used in URLs). So, start with \. It couldn't be \\ (because it prints the character \) and \$ was pretty weird, so \-- was chosen in alignment with the -- used by Lua.

Enhancement

• Plume comment will now work in Lua blocks.
• Remove useless lines from traceback.
• Warnings will be printed only one time per faulty code chunk.

Fixes

• Fix wrong space mode name.
• Plume no longer see a==4 as a statement.
• Fix an error causing Plume to crash if a for loop go over the iteration limit.
