Shawn O. Pearce	bea39c2ddb	git-gui: Remove empty blank line at end of blame The blame viewer has this silly blank line at the bottom of it; we really don't want to see it displayed as we will never get any blame data for that line (it doesn't exist in the source).

Shawn O. Pearce	d89a494fca	git-gui: Cleanup blame::new widget initialization A lot of this code was pre-class, which meant that I just sort of copied and pasted my way through it, rather than being really smart and using a variable for each widget's path name. Since we have a field for each path, we can use those throughout the constructor and make things a lot neater. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	a46fe1c1c0	git-gui: Add a 4 digit commit abbreviation to the blame viewer We now show the first 4 digits of each commit in the left most column of our blame viewer, before the line numbers. These are drawn as the data becomes available from git-blame --incremental, and helps the user to visually group lines together. I'm using only the first 4 digits because within a given cluster of lines its unlikely that two neighboring commits will have the same 4 digit prefix. Signed-off-by: Shawn O.

Shawn O. Pearce	b8848f7753	git-gui: Allow as few as 0 lines of diff context Johannes Sixt pointed out that dropping to 0 lines of context does allow the user to get more fine-grained hunk selection, especially since we don't currently support "highlight and apply (or revert)".

Shawn O. Pearce	905d9c9653	git-gui: Allow creating a branch when none exists If the user has no branches at all (their refs/heads/ is empty) and they are on a detached HEAD we have a valid repository but there are no branches to populate into the branch pulldown in the create branch dialog. Instead of erroring out we can skip that part of the dialog, much like we do with tracking branches or tags when the user doesn't have any. Signed-off-by: Shawn O.

Shawn O. Pearce	76486bbefb	git-gui: Format author/committer times in ISO format This is a simple change to match what gitk does when it shows a commit; we format using ISO dates (yyyy-mm-dd HH:MM:SS). Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	0511798f06	git-gui: Cleanup minor nits in blame code We can use [list ...] rather than "", especially when we are talking about values as then they are properly escaped if necessary. Small nit, but probably not a huge deal as the only data being inlined here is Tk paths. Some of the lines in the parser code were longer than 80 characters wide, and they actually were all the same value on the end part of the line. Rather than keeping the mess copied-and-pasted around we can set the last argument into a local variable and reuse it many times. The commit display code was also rather difficult to read on an 80 character wide terminal, so I'm moving it all into a double quoted string that is easier to read. Signed-off-by: Shawn O.

Shawn O. Pearce	a0db0d61fb	git-gui: Generate blame on uncommitted working tree file If the user doesn't give us a revision parameter to our blame subcommand then we can generate blame against the working tree file by passing the file path off to blame with the --contents argument. In this case we cannot obtain the contents of the file from the ODB; instead we must obtain the contents by reading the working directory file as-is. Signed-off-by: Shawn O.

Shawn O. Pearce	685caf9af6	git-gui: Convert blame to the "class" way of doing things Our blame viewer code has historically been a mess simply because the data for multiple viewers was all crammed into a single pair of Tcl arrays. This made the code hard to read and even harder to maintain. Now that we have a slightly better way of tracking the data for our "meta-widgets" we can make use of it here in the blame viewer to cleanup the code and make it easier to work with long term.

Shawn O. Pearce	28bf928cf8	git-gui: Don't attempt to inline array reads in methods If a variable reference to a field is to an array, and it is the only reference to that field in that method we cannot make it an inlined [set foo] call as the regexp was converting the Tcl code wrong. We were producing "[set foo](x)" for "$foo(x)", and that isn't valid Tcl when foo is an array. So we just punt if the only occurance has a ( after it. Signed-off-by: Shawn O.

Shawn O. Pearce	c74b6c66f0	git-gui: Convert browser, console to "class" format Now that we have a slightly easier method of working with per-widget data we should make use of that technique in our browser and console meta-widgets, as both have a decent amount of information that they store on a per-widget basis and our current approach of handling it is difficult to follow.

Shawn O. Pearce	1f07c4e5ce	git-gui: Define a simple class/method system As most of the git-gui interface is based upon "meta-widgets" that need to carry around a good deal of state (e.g. console windows, browser windows, blame viewer) we have a good deal of messy code that tries to store this meta-widget state in global arrays, where keys into the array are formed from a union of a unique "object instance id" and the field name. This is a simple class system for Tcl that allows us to hide much of that mess by making Tcl do what it does best; process strings to manipulate its own code during startup. Each object instance is placed into its own namespace. The namespace is created when the object instance is created and the namespace is destroyed when the object instance is removed from the system. Within that namespace we place variables for each field within the class; these variables can themselves be scalar values or full-blown Tcl arrays. A simple class might be defined as: class map { field data field size 0 constructor {} { return $this } method set {name value} { set data($name) $value incr size } method size {} { return $size } ifdeleted { return 0 } } All fields must be declared before any constructors or methods. This allows our class to generate a list of the fields so it can properly alter the definition of the constructor and method bodies prior to passing them off to Tcl for definition with proc. A field may optionally be given a default/initial value. This can only be done for non-array type fields. Constructors are given full access to all fields of the class, so they can initialize the data values. The default values of fields (if any) are set before the constructor runs, and the implicit local variable $this is initialized to the instance identifier. Methods are given access to fields they actually use in their body. Every method has an implicit "this" argument inserted as its first parameter; callers of methods must be sure they supply this value. Some basic optimization tricks are performed (but not much). We try to only upvar (locally bind) fields that are accessed within a method, but we err on the side of caution and may upvar more than we need to. If a variable is accessed only once within a method and that access is by $foo (read) we avoid the upvar and instead use [set foo] to obtain the value. This is slightly faster as Tcl does not need to lookup the variable twice. We also offer some small syntatic sugar for interacting with Tk and the fileevent callback system in Tcl. If a field (say "foo") is used as "@foo" we insert instead the true global variable name of that variable into the body of the constructor or method. This allows easy binding to Tk textvariable options, e.g.: label $w.title -textvariable @title Proper namespace callbacks can also be setup with the special cb proc that is defined in each namespace. [cb _foo a] will invoke the method _foo in the current namespace, passing it $this as the first (implied) parameter and a as the second parameter. This makes it very simple to connect an object instance to a -command option for a Tk widget or to a fileevent readable or writable for a file channel. Signed-off-by: Shawn O.

Shawn O. Pearce	cc1f83fbdf	git-gui: Allow shift-{k,j} to select a range of branches to merge I found it useful to be able to use j/k (vi-like keys) to move up and down the list of branches to merge and shift-j/k to do the selection, much as shift-up/down (arrow keys) would alter the selection.

Shawn O. Pearce	ebcaadabcb	git-gui: Use vi-like keys in merge dialog Since we support vi-like keys for scrolling in other UI contexts we can easily do so here too. Tk's handy little `event generate' makes this a lot easier than I thought it would be. We may want to go back and fix some of the other vi-like bindings to redirect to the arrow and pageup/pagedown keys, rather than running the view changes directly. I've bound 'v' to visualize, as this is a somewhat common thing to want to do in the merge dialog. Control (or Command) Return is also bound to start the merge, much as it is bound in the main window to activate the commit. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	1fc4ba86f8	git-gui: Include commit id/subject in merge choices When merging branches using our local merge feature it can be handy to know the first few digits of the commit the ref points at as well as the short description of the branch name. Unfortunately I'm unable to use three listboxes in a row, as Tcl freaks out and refuses to let me have a selection in more than one of them at any given point in time. So instead we use a fixed width font in the existing listbox and organize the data into three columns. Not nearly as nice looking, but users can continue to use the listbox's features.

Shawn O. Pearce	349f92e3a2	git-gui: Show all possible branches for merge Johannes Sixt pointed out that git-gui was randomly selecting which branch (or tag!) it will show in the merge dialog when more than one ref points at the same commit. This can be a problem for the user if they want to merge a branch, but the ref that git-gui selected to display was actually a tag that points at the commit at the tip of that branch. Since the user is looking for the branch, and not the tag, its confusing to not find it, and worse, merging the tag causes git-merge to generate a different message than if the branch was selected. While I am in here and am messing around I have changed the for-each-ref usage to take advantage of its --tcl formatting, and to fetch the subject line of the commit (or tag) we are looking at. This way we could present the subject line in the UI to the user, given them an even better chance to select the correct branch. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	a6c9b081b6	git-gui: Move merge support into a namespace Like the console procs I have moved the code related to merge support into their own namespace, so that they are isolated from the rest of the world. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	60aa065f69	git-gui: Allow vi keys to scroll the diff/blame regions Users who are used to vi and recent versions of gitk may want to scroll the diff region using vi style keybindings. Since these aren't bound to anything else and that widget does not accept focus for data input, we can easily support that too. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	a35d65d9c8	git-gui: Move console procs into their own namespace To help modularize git-gui better I'm isolating the code and variables required to handle our little console windows into their own namespace. This way we can say console::new rather than new_console, and the hidden internal procs to create the window and read data from our filehandle are off in their own private little land, where most users don't see them.

Shawn O. Pearce	f522c9b5ed	git-gui: Refactor into multiple files to save my sanity I'm finding it difficult to work with a 6,000+ line Tcl script and not go insane while looking for a particular block of code. Since most of the program is organized into different units of functionality and not all users will need all units immediately on startup we can improve things by splitting procs out into multiple files and let auto_load handle things for us. This should help not only to better organize the source, but it may also improve startup times for some users as the Tcl parser does not need to read as much script before it can show the UI. In many cases the user can avoid reading at least half of git-gui now. Unfortunately we now need a library directory in our runtime location. This is currently assumed to be $(sharedir)/git-gui/lib and its expected that the Makefile invoker will setup some sort of reasonable sharedir value for us, or let us assume its going to be $(gitexecdir)/../share. We now also require a tclsh (in TCL_PATH) to just run the Makefile, as we use tclsh to generate the tclIndex for our lib directory. I'm hoping this is not an unncessary burden on end-users who are building from source. I haven't really made any functionality changes here, this is just a huge migration of code from one file to many smaller files. All of the new changes are to setup the library path and install the library files. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
