feature Request: user tags window/list

Post by raz » Wed Aug 10, 2005 2:12 pm

One feature that I liked in jEdit was the plugin for the TODO / FIXME tag window. That is, it would parse the current buffer, and display all the user defined tags, with a brief or full synopsis of the tag.

For example, if I put this in my source code:

// TODO: add better error checking here


// FIXME: use return value!

// WARN: this is a hack

or whatever my set of tags are. They would show up in a window, sorted however I wanted (by group, by position in the file, etc), and clicking on them would move the cursor to the line in question.

Is this feature a possibility, or should I get off my lazy <expletive> and write a script to do this (is it possible?).

Thanks!

raz.

Hi Raz,
That is, it would parse the current buffer, and display all the user defined tags, with a brief or full synopsis of the tag.
Inknow the feature you are referring to. I will add it to the Zeus todo list, but at this stage I would say it might be quite some time off :(

This type of feature really needs a seperate tool window panel (ie docked at the bottom edge) to hold this and any other tool windows in some sort of tabbed panel.

But adding such a tabbed tool panel will require a lot of code rework and is definitely no simple task :(
Is this feature a possibility or should I get off my lazy <expletive> and write a script to do this (is it possible?).


In the mean time I have come up with a first draft macro script that does something similar.

My quick and dirty macro searches the current file for a set of patterns and displays the results in a tool window. Clicking on the items then takes you back to the original file at the correct line number:

Code: Select all

--
--        Name: Pattern Searching
--
--    Language: Lua Macro
--
-- Description: This macro searches the current file for a list of patterns
--              and displays the results in a tool window:
--

function create_results_file(filename, results, count)

    local result = 0

    -- try to create the file
    file_results = io.open(filename, "w+")

    if file_results ~= nil then
        local index = 0

        while index < count do
            local line = index + 1

            -- write out the text found
            file_results:write(results[index + 1])

            -- write out the CRLF
            file_results:write("\n")

            -- next line
            index = index + 1
        end

        file_results:close()

        result = 1;
    else
        -- failed to create file
        message_box(1, "Error creating file!")
    end

    return result
end

function find_pattern(pattern, results, count)

    local line_current = 0
    local line_total = get_line_count()

    -- the name of the current document
    local file_name = macro_tag("$fn")

    -- search the current file for the 'pattern'
    while line_current < line_total do
        -- get the text
        local line_text = get_line_text(line_current)

        local len = string.len(line_text)

        if len > 0 then
            -- look for all todo lines
            if string.find(line_text, pattern)~= nil then
                -- build up a full result text
                local result_text = "\"" .. file_name .. "\"" .. " [" .. line_current .. "]" .. line_text

                -- save the result into the table
                results[count + 1] = result_text;

                -- one more item found
                count = count + 1
            end
        end

        -- next line
        line_current = line_current + 1
    end

    return count
end

function key_macro()
    local count   = 0
    local results = {}

    local pattern = "todo:"

    -- search the current file for these patterns
    count = find_pattern("todo:" , results, count)
    count = find_pattern("hack:" , results, count)
    count = find_pattern("fixme:", results, count)

    if count == 0 then
        -- nothing found
        message("No pattern items found in current file!");
        beep()
    else
        local filename = "d:\\temp\\test.txt"

        -- create a temp results file
        if create_results_file(filename, results, count) == 1 then
            -- display the results in a tool window
            file_open_tool(filename, "My Todo List")
        end
    end
end

key_macro() -- run the macro
Cheers Jussi

Thanks for the script!
I'll try it out in the next few days and let you know.

Thanks!
