MORIN Date: Sun, 8 Jun 2014 14:15:15 +0000 (+0200) Subject: support/scripts: introduce a symbol formatter to generate package lists X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fe696d7c658ee498ab07f1490588417e102e47f4;p=buildroot.git support/scripts: introduce a symbol formatter to generate package lists Currently, we can generate two different tables of packages: - a single-column table with the symbols' prompts, - a two-column table with the symbols' prompts and locations in the menuconfig. For virtual packages, this is not enough, since we will have to display more columns, with different content: - the virtual package name (but such symbols do not have a prompt) - the symbol name - the providers for the virtual package So, instead of having a single function that knows how to generate any table, introduce a formatter function that is passed as argument to, and called by format_asciidoc_table(). Such formatter functions are responsible for providing: - the layout of the table (number of columns, column arrangement), - the formatted header line, - a formatted line for a symbol. What the formatter should ouput depends on its arguments: - if none are passed, the layout is returned, - if the header label is passed, it returns the formatted header line, - otherwise, it returns the formatted line for a symbol. Two formatter functions are introduced in this changeset, to replace the current 'sub_menu' feature: - _format_symbol_prompt() to display a one-column table with only the symbols' prompts, - _format_symbol_prompt_location() to display a two-column table with the symbols' prompts and locations. This will help us to later introduce a new formatter to generate a table for virtual packages. [Thanks to Samuel for his pythonistic help!] Signed-off-by: "Yann E.
