<p>Start by selecting your target system from the tree on the left.
The panel on the right will show the CPU that will be selected, as well
as the symbol files and extension scripts that will be loaded by default.
Move symbol file and extension script docs into manual Once upon a time, symbol files and extension scripts could only be defined in the RuntimeData directory, so having the documentation there made sense. Since both of these things can now be defined in project directories, the documentation belongs in the manual. (issue #27)

<p>The first time you save the project (with <samp>File &gt; Save</samp>),
you will be prompted for the project name. It's best to use the
data file's name with "<samp>.dis65</samp>" added, so this will be set as
the default. The data file's name is not stored in the project file,
so if you pick a different name, or save the project in a different

<p>SourceGen will try to open a data file with the project's name,
minus the ".dis65". If it can't find a file with that name, or if there's
something wrong with it (e.g. the CRC doesn't match), you will be given
the opportunity to specify the location of the data file to use.</p>
<p>If non-fatal problems with the file are detected, a warning will be
shown. If it's something simple, like a missing .sym65 or extension
script file, you'll be notified. If it's something more complicated,
e.g. the project has a comment on an offset that doesn't exist, you
will be warned that the problematic data has been deleted, and will be
Open damaged projects in read-only mode If we detect a problem that requires intervention during loading, e.g. we find unknown elements because we're loading a file created by a newer version, default to read-only mode. Read only mode (1) refuses to apply changes, (2) refuses to add changes to the undo/redo list, and (3) disables Save/SaveAs. The mode is indicated in the title bar. Also, flipped the order of items in the title bar so that "6502bench SourceGen" comes last. This allows you to read the project name in short window title snippets.

Add "uninitialized data" format type This allows regions that hold variable storage to be marked as data that is initialized by the program before it is used. Previously the choices were to treat it as bulk data (initialized) or junk (totally unused), neither of which are correct. This is functionally equivalent to "junk" as far as source code generation is concerned (though it doesn't have to be). For the code/data/junk counter, uninitialized data is counted as junk, because it technically does not need to be part of the binary.

Rename "hint" in UI and documentation Before: Hint As Code Entry Point Hint As Data Start Hint As Inline Data Remove Hints After: Tag Address As Code Start Point Tag Address As Code Stop Point Tag Bytes As Inline Data Remove Analyzer Tags The goal is to reduce confusion. The old nomenclature was causing problems because it's inaccurate -- they're directives, not hints -- and made it look like you need to mark data items explicitly. The new action names emphasize the idea that you should be tagging a single address for start/stop, not blanketing a region. This change updates the user interface, manual, and tutorials, but does not change how the items are referred to in code, and does not change how the program works. (issue #89)

In most cases this is equivalent to simply editing the various items and clicking the "default" format radio button, but the feature can be used to remove data formats that end up inside multi-byte instructions. Instructions with such formats cause warnings and were tricky to fix. Labels embedded in multi-byte items are also tricky to remove, so this clears those as well. It does not remove visible labels. This is done in a single pass, which means that labels that would become visible after the formatting is cleared will still be removed.

Minor changes to local variable tables Split "edit local variable table" into "create" and "edit prior". The motivation is to allow the user to make changes to the most recently defined table without having to go search for it. Having table creation be an explicit action, rather than something that just happens if you edit a table that isn't there, feels reasonable. Show table offset in LV table edit dialog, so if you really want to go find it there's a (clumsy) way to do so. Increased the maximum width of a variable from 4 to 8. (This is entirely arbitrary.)

The old nomenclature was causing problems because it's inaccurate -- they're directives, not hints -- and made it look like you need to mark data items explicitly.

Add "remove formatting" action This action removes operand formatting from all code and data in the selected range. In most cases this is equivalent to simply editing the various items and clicking the "default" format radio button, but the feature can be used to remove data formats that end up inside multi-byte instructions. Instructions with such formats cause warnings and were tricky to fix. Labels embedded in multi-byte items are also tricky to remove, so this clears those as well. It does not remove visible labels. This is done in a single pass, which means that labels that would become visible after the formatting is cleared will still be removed. Also, fix inclusion of address range end lines when restoring the selection. Their peculiar nature -- being associated with the offset of the last byte of multi-byte items -- was interfering with the selection save code.

Show "idx" for indexed accesses in References window Sometimes it's useful to know whether an address referenced by a function is a direct access, or is being used as a base address. (I'm somewhat undecided on this one, since it clutters up the list a bit. Giving it a try.)
2020-05-02 21:09:53 +00:00
<p>References from instructions that use indexed addressing
(e.g. <code>LDA addr,Y</code>) will also show "idx" to indicate that
the instruction is using the location as a base address.</p>
Show "ptr" for pointer use in cross-reference list Consider: LDA $00 loads a value from address $00 LDA $00,X might load from $00, or might not LDA ($00),Y dereferences $00 as a 16-bit pointer LDA ($00,X) dereferences a pointer, not necessarily from $00 When perusing the cross-reference list, it's useful to be able to tell whether an instruction is accessing the location, using it as a base address, or deferencing it as a pointer. We now show "ptr" in the list for pointer dereferences. (We already showed "idx" for indexed accesses.)
2020-09-04 20:26:41 +00:00
<p>References from instructions that treat the address as a pointer
(e.g. <code>LDA (dp),Y</code>) will show "ptr". This makes it easy

pointer from those that are reading or writing the pointer itself.</p>

Add Problem List Viewer to debug menu The analyzer sometimes runs into things that don't seem right, like hidden labels or references to non-existent symbols, but has no way to report them.

<p>When an equate directive (generated for platform and project
symbols) or local variable assignment is selected, the References
window will show all references to that symbol. Unlike in-file
references, only the uses of that symbol are shown. So if you have
both a project symbol and a local variable for address $30, they
will show disjoint sets of references. Furthermore, if you explicitly
format an instruction operand as hex, e.g. <code>LDA $30</code>, it will
not appear in either set because it's not a symbolic reference.</p>
<p>The cross-reference data is used to generate the set of equate
directives at the top of the listing. If nothing references a platform
or project symbol, an equate directive will not be generated for it.</p>

In most cases this is equivalent to simply editing the various items and clicking the "default" format radio button, but the feature can be used to remove data formats that end up inside multi-byte instructions. Instructions with such formats cause warnings and were tricky to fix. Labels embedded in multi-byte items are also tricky to remove, so this clears those as well. It does not remove visible labels. This is done in a single pass, which means that labels that would become visible after the formatting is cleared will still be removed. Also, fix inclusion of address range end lines when restoring the selection.

Add Navigate > Jump to Operand If you double-click on the opcode of an instruction whose operand is an address or equate, the selection jumps to that address. This feature is now available in the Navigate menu, with the keyboard shortcut Ctrl+J. While testing the feature I noticed that the keyboard focus wasn't following the selection, so if you jumped to an address and then used the up/down arrows, you jumped back to the previous location. (This was true when double-clicking an opcode to jump; it was just less noticeable since the next action was likely mouse-based.)

(or <samp>Stop Point</samp>). Because these indicate a transition

<p>For inline data that follows a

<p>Tip: while code start points and inline data tagging are both very

<h3 id="remove-formatting">Remove Formatting</h3>
Add "remove formatting" action This action removes operand formatting from all code and data in the selected range. In most cases this is equivalent to simply editing the various items and clicking the "default" format radio button, but the feature can be used to remove data formats that end up inside multi-byte instructions. Instructions with such formats cause warnings and were tricky to fix. Labels embedded in multi-byte items are also tricky to remove, so this clears those as well. It does not remove visible labels. This is done in a single pass, which means that labels that would become visible after the formatting is cleared will still be removed. Also, fix inclusion of address range end lines when restoring the selection. Their peculiar nature -- being associated with the offset of the last byte of multi-byte items -- was interfering with the selection save code. This does not add them to the selection when an address region deletion is undone, since technically they weren't part of the selection. Also, moved Edit Note higher in the Actions menu.

This removes the visible formatting as well as any formatting instructions

such things in the <a href="#messages">message list</a>.)</p>

Make hint application less annoying Two changes: (1) Code and data hints are now only applied to the first byte on each selected line. This allows you to slap a code hint on a string without lighting up the whole string. Inline-data hints and hint removal work as before. (2) Added a menu item (with Ctrl+D as shortcut) to toggle the state of the uncategorized data analyzer. This makes it easy to turn off the feature that put the code into a string in the first place.

You can exclude the table by removing it from the template, which right now you'd need to do anyway to get rid of the H2 header and other framing. To make this work correctly as an option we'd need to parse the "div" in the template file and strip the whole section, or split the template into multiple parts that get included as needed.
